Warfarin (commonly known by its trade name, Coumadin) is an oral anticoagulant that has been widely used for the prevention and treatment of thromboembolic disorders. Despite its clinical benefits, warfarin therapy is complicated by a very narrow therapeutic index and wide inter-individual variability in dose requirements. This variability represents a major challenge for clinicians, as inappropriate dosing may lead to serious adverse outcomes such as bleeding or thrombotic events. A growing body of evidence suggests that genetic polymorphisms are among the most important factors contributing to this variability, particularly those involving the Vitamin K Epoxide Reductase Complex Subunit 1 (VKORC1) gene. VKORC1 encodes a key enzyme that functions as a bottleneck in the vitamin K cycle, playing an essential role in the regeneration of reduced vitamin K (VKH). This active form of vitamin K is required for the γ-carboxylation of vitamin K–dependent clotting factors, including prothrombin and other coagulation proteins. Polymorphisms within VKORC1 can significantly alter the enzyme’s expression and activity, thereby modifying an individual’s sensitivity to warfarin. One of the most clinically relevant variants is the -1639G>A (rs9923231) polymorphism, which reduces VKORC1 transcription and subsequently decreases enzyme activity. Patients carrying the A allele often exhibit increased sensitivity to warfarin and therefore require lower maintenance doses compared to those with the G allele. Understanding these genetic influences not only improves our knowledge of warfarin pharmacogenomics but also highlights the importance of personalized medicine in anticoagulant therapy. Incorporating VKORC1 genotyping into clinical practice could optimize dose prediction, minimize adverse events, and enhance the safety and effectiveness of warfarin therapy. This narrative review aims to provide an in-depth discussion of the complex role of VKORC1 in vitamin K metabolism and its impact on warfarin sensitivity, thereby underscoring the critical relevance of genetic factors in guiding individualized anticoagulation therapy.

This study evaluates the effectiveness of the SAP accounting information system in supporting the implementation of the Independent Learning–Independent Campus (MBKM) Internship Program at PT Japfa Comfeed Indonesia Tbk, Gedangan Unit. SAP, as an integrated Enterprise Resource Planning (ERP) system, was adopted to replace the previous desktop-based system, which had significant limitations, such as restricted local access, dependence on additional licenses, and lower integration capabilities across departments. The main objective of this research is to determine how SAP contributes to improving organizational efficiency while simultaneously providing practical learning opportunities for students participating in the MBKM internship program. A descriptive qualitative approach was employed, with data collected through direct observation of company operations, semi-structured interviews with student interns and field supervisors, and analysis of company documentation. The findings indicate that the use of SAP has enhanced efficiency, accuracy, and speed in recording and reporting financial transactions. Through their internship, students engaged directly in business processes, particularly in handling purchase requisitions, reimbursement procedures, and asset management activities. This exposure enabled students to develop a deeper understanding of integrated financial systems and the workflow of a large-scale agribusiness corporation. Although several technical challenges were encountered, particularly in the form of temporary network disruptions, such issues did not substantially hinder the system’s overall performance. The availability of prompt technical support from the company’s IT team minimized potential negative impacts and ensured system continuity. Beyond improving corporate financial governance, SAP also offered valuable experiential learning for interns, bridging theoretical knowledge acquired in academic settings with real-world industrial applications. Overall, the study concludes that SAP functions not only as a strategic enterprise tool for the company but also as an effective educational medium that supports the success of the MBKM internship program.

The Dandu Bridge is one of the important infrastructures that functions as a land transportation link on the Suko-Sowominangun section, Lamongan Regency. The current condition shows that the bridge surface has suffered a lot of damage in the form of holes that can interfere with the smooth flow of traffic and endanger the safety of road users. Therefore, regular maintenance is needed so that the function of the bridge as a public facility remains optimal. One of the maintenance methods used is the Detailed Bridge Inspection Report (LPMJ), which aims to identify the condition of the bridge components as a whole. Field work practices carried out by students of the Lamongan Institute of Technology and Business in March-April 2025 are a means to understand the factors that cause damage. The results of the observation show that the damage is not only caused by structural factors, but also by non-structural aspects such as lack of awareness of road users and lack of communication with the surrounding community. Therefore, intensive education is needed for the community regarding the importance of maintaining the sustainability of the bridge's function, including the installation of proper traffic signs to minimize damage. In the LPMJ method, the upper structure components examined include floor plates, girders, and joints. Meanwhile, the lower structure includes pillars, abutments, and foundations. The bridge equipment that was observed included sidewalks, waterways, and railings. Maintenance should not only be focused on physical improvements, but also on social management that involves the active participation of the community, especially in areas with high traffic intensity. In conclusion, the maintenance efforts of the Dandu Bridge require an integrated approach that combines technical improvements and social empowerment, so that the sustainability of its function can be maintained for the long term.

The manual, paper-based election of the Student Council President faces various challenges, such as the lengthy vote counting process and the potential for errors in the recapitulation. To address these issues, this study designed a web-based e-voting information system at SMK Negeri 4 Tangerang Regency. This system was built using the Rapid Application Development (RAD) method, which emphasizes speed of development through iteration and prototyping based on user feedback. The development results indicate that e-voting can accelerate voting and vote counting, provide real-time results, and reduce paper usage. This system has been tested using blackbox testing, proving that all functions work as expected and are easily accessible to students. The study concludes that the implementation of web-based e-voting can improve efficiency, security, and transparency in the election of the Student Council President, with suggestions for system usage simulations and regular usability evaluations. Furthermore, this study also shows that the implementation of a web-based e-voting system can reduce the potential for fraud that often occurs in manual elections. With an automated and integrated system, every vote cast by voters is recorded accurately, reducing human error in the vote counting process. System security is also maintained through authentication mechanisms that ensure only authorized users can vote, as well as data encryption to protect sensitive information. This increases voter confidence in the election results, as the process is more transparent and free from manipulation. Furthermore, although the e-voting system has proven effective in increasing election efficiency and accuracy, the study also recommends the need for training for system users, both students and election committee members, to ensure they can utilize the system optimally. Continuous evaluation of the system's usability is also crucial to ensure that the interface remains user-friendly and easily accessible to all parties.

International trade involves cross-border buying and selling activities between countries, which in practice requires various transportation documents to ensure legal certainty and smooth operations. One of the main documents used is the Bill of Lading (Konosemen), which is a dated letter issued by the carrier as proof of receipt of goods to be transported to a certain destination and delivered to a specified recipient. The Bill of Lading has three essential functions: as a receipt of goods, as evidence of ownership, and as proof of a transportation contract. However, in practice, there are still frequent problems that hinder the optimal function of the Bill of Lading. One notable case is APL Co. Pte. Ltd. v. CV. Dua Sekawan Sejati, which involved discrepancies between the goods shipped and those stated in the Bill of Lading. This study adopts a normative juridical method by examining applicable legal provisions and theoretical concepts related to the law of contracts and transportation. The findings show that discrepancies between the goods shipped and those listed in the Bill of Lading constitute a breach of promise or default under Article 1320 of the Indonesian Civil Code. The Bill of Lading, in this case, serves as a legally binding transportation contract that obligates both parties to fulfill their respective responsibilities. Failure by one party to comply with the terms of the contract results in legal consequences in the form of claims for compensation by the aggrieved party. This research emphasizes the importance of accuracy and accountability in the issuance and use of Bills of Lading in international trade to avoid disputes and ensure legal certainty. Strengthening the regulation and enforcement of Bill of Lading functions is crucial for protecting the rights of parties engaged in cross-border trade.

This study aims to describe and analyze the implementation of inclusive education management at SMP Negeri 4 Babelan. Inclusive education is an educational approach that provides learning opportunities for all students without discrimination, including those with special educational needs (ABK). This concept emphasizes the importance of a friendly, adaptive, and responsive learning environment to student diversity. This study uses a qualitative descriptive approach with data collection techniques through in-depth interviews, participatory observation, and documentation studies. Informants in this study consisted of the principal, regular teachers, special assistant teachers, students with special needs, and their parents. The results of the study indicate that inclusive education management at SMP Negeri 4 Babelan has been implemented through four main management functions, namely: (1) strategic planning integrated into the annual school work program, including budget allocation for inclusion needs; (2) organizing an inclusion team involving teachers, education staff, and the school committee; (3) implementing adaptive learning based on a differentiation and individualization approach, adjusted to students' abilities and learning styles; and (4) evaluations conducted periodically to assess students' academic and social-emotional development, as well as the effectiveness of the inclusion program as a whole. However, this study also identified several obstacles, including a limited number of special assistant teachers, a lack of professional training for regular teachers, and a lack of supporting facilities such as therapy rooms or learning aids. Furthermore, factors supporting the program's success include the school leadership's commitment to mainstreaming inclusion, a collaborative spirit among teachers, and the support and active involvement of parents. Based on these findings, this study recommends several strategic steps, such as strengthening teacher training in inclusive classroom management and adding special assistant teachers as needed.

This study aims to analyze the factors that influence students' learning motivation in the Lathe Engineering subject in class XI of the Department of Machining Engineering at SMK Negeri 1 Padang. Several variables studied include learning interest, ideals, friendship environment, and family environment, each of which acts as an independent variable, while learning motivation functions as a dependent variable. The method used in this study is quantitative with a correlational approach, where the research sample consisted of 51 students selected using a saturated sampling technique, namely sampling that covers the entire population in the class. The instrument used in this study was a questionnaire with a Likert scale that has been tested for validity and reliability to ensure that the measuring instrument used is able to extract accurate and consistent data. The data obtained were then analyzed using multiple linear regression techniques with the help of SPSS version 26 to determine the effect of each variable on student learning motivation. The results of the study indicate that partially, learning interest and friendship environment have a significant influence on student learning motivation. Students who have a high interest in the Lathe Engineering subject tend to have better learning motivation, and positive relationships with their friends also increase their enthusiasm for learning. In contrast, the variables of ideals and family environment did not show a significant influence on students' learning motivation in the context of this study. Although ideals and family support are often considered important factors in education, the results of this study indicate that external factors such as friendships are more dominant in influencing students' learning motivation. Simultaneously, all four variables significantly influenced students' learning motivation, with the friendship environment being the most dominant factor.

This study aims to explore the relationship between work motivation and discipline on the performance achievement of Catholic Religious Education (PAK) teachers in the Semarang region. The research uses a quantitative survey approach, collecting data from 15 PAK teachers through a validated questionnaire. The instruments used to measure work motivation are based on Maslow’s hierarchy of needs for the motivational aspect, while discipline is measured using indicators developed by Rivai, and performance achievement is evaluated based on parameters defined by Robbins. The findings show that motivational drive contributes 50.5% to performance achievement (R² = 0.505, p = 0.003). This indicates that work motivation has a significant impact on performance, although its contribution is lower compared to discipline. In contrast, discipline contributes more significantly to performance achievement, accounting for 66.2% (R² = 0.662, p = 0.000). This suggests that discipline is a more dominant factor in improving the performance of Catholic Religious Education teachers, as discipline is critical in achieving optimal performance. Simultaneous analysis reveals that the combination of motivation and discipline explains 72.6% of the variation in performance achievement (R² = 0.726, F = 13.893, p = 0.000). This result indicates that both variables are significantly related to performance achievement when considered together. However, partial tests show that only discipline has a significant independent impact on teacher performance, with p = 0.121, while motivation does not have a significant effect when considered separately. This study concludes that discipline functions as the main mediator in the relationship between work motivation and performance achievement. Therefore, it is essential to strengthen discipline in efforts to improve teacher performance, particularly in the context of Catholic Religious Education.

This study aims to examine creative strategies for fiction writing involving collaboration between humans and AI (ChatGPT) in the Kompasiana blogger community in Semarang. Using a qualitative approach, this study collected data through in-depth interviews with four informants active in AI-assisted fiction writing. The interviews revealed a shift in the role of AI, where AI no longer functions solely as a technical tool but rather as an imaginative partner collaborating with writers in the creative process. During the writing process, writers negotiated with AI regarding style and story structure, and reflected deeply on their creative process. They also faced ethical dilemmas, particularly regarding the originality and authenticity of their work, arising from the use of AI technology. While AI writers provided new ideas and inspiration, they also demanded further considerations regarding copyright and author credibility. These findings were analyzed using the theories of Extended Mind, Distributed Cognition, and Reflective Practice to understand the dynamics of human-machine interaction in a creative context. This study proposes a dialectical and symbiotic model of creative interaction, in which writers and AI influence each other in producing fictional works. This model emphasizes that AI-assisted fiction writing is not just about efficiency in producing work, but also a process of redefining creative agency. This research demonstrates how human-machine collaboration in digital literacy can change our perspective on creative roles and ethics in the world of writing. Furthermore, this research explores the impact of AI use on the learning process of writers within the blogging community. AI, in this case ChatGPT, not only contributes to the final product but also plays a role in broadening the writer's insight into writing techniques, idea exploration, and character development.

This study aims to describe the types and functions of directive speech acts found in Indonesian language learning interactions at SMP Negeri 3 Gianyar. Employing a descriptive qualitative research design, the data were obtained through note-taking and recording of teacher–student interactions during classroom activities. The analysis followed four main stages: data reduction, data collection, data display, data interpretation, and conclusion drawing. Directive speech acts, which are utterances intended to prompt the listener to perform a specific action, are an essential component of classroom discourse, as they directly influence student participation, classroom management, and instructional clarity. The findings reveal a total of 109 directive speech act utterances produced by both teachers and students. These utterances are categorized into six types: 18 requests, 52 questions, 22 commands, 3 prohibitions, 10 permissions, and 4 pieces of advice. Each type of directive speech act is used to achieve specific communicative purposes. Further analysis identified 11 distinct functions realized within these utterances, namely: requesting, inviting, pleading, asking, wishing, demanding, directing, instructing, prohibiting, permitting, and advising. For instance, teachers predominantly employed questioning and commanding functions to guide learning processes, check comprehension, and maintain classroom order, while students tended to use requesting and asking functions to seek clarification or assistance. The results of this research highlight the significant role of directive speech acts in facilitating interactive and goal-oriented communication in the language learning environment. Understanding the types and functions of such speech acts can provide valuable insights for educators in designing effective communication strategies that foster active learning, encourage student engagement, and create a positive classroom atmosphere. This study contributes to the broader field of pragmatics and educational linguistics by emphasizing the practical application of speech act theory in Indonesian language teaching contexts.

This study examines the phenomenon of the religious jargon “Go Berkah No Riba” (Go Blessed, No Interest) as a digital marketing communication strategy employed by entrepreneurs on social media, particularly Facebook. Using a descriptive qualitative approach and visual discourse analysis, this research seeks to understand how the jargon is interpreted, constructed, and widely disseminated in the context of product marketing and business opportunities. The findings indicate that “Go Berkah No Riba” functions not only as a marker of religious identity but also as a rhetorical device that combines spiritual values with aspirations for material success. Visual analysis of promotional materials, such as flyers and Facebook posts, reveals the use of hyperbolic language, symbolic imagery—such as the Kaaba and piles of money—and religious narratives designed to build credibility and persuade potential consumers. The integration of religious elements with economic appeal creates a sharia-compliant business image that simultaneously promises profitability. However, the study also uncovers ambiguity in the use of this jargon. On the one hand, it can strengthen the image of a business operating ethically according to Islamic principles. On the other hand, it risks being exploited merely as a marketing gimmick without a strong foundation in ethical business practices. This creates the potential for a gap between the religious message communicated and the actual business conduct. The findings underscore the importance of critical literacy in understanding religious communication strategies within the digital business sphere. Consistency between religious messaging and real-world business practices is crucial for maintaining consumer trust and avoiding the excessive commodification of religious values. Therefore, this study contributes to a deeper understanding of the dynamics of religion-based marketing communication in the era of digital transformation.

This type of research is research and development using the ADDIE model (Analysis, Design, Development, Implementation, and Evaluation). The research was conducted at SMA Negeri 1 Malinau with the research subject of class X-3 students totaling 35 students. Data collection was carried out using interview techniques, observation, e-LKPD validation sheets, pretest-posttest, and questionnaires. To determine the validity, the e-LKPD assessment sheet of material and media experts was used, practicality used student and teacher response questionnaires, and effectiveness used mathematics problem solving ability test questions and student self-confidence questionnaires. Data analysis consisted of qualitative data analysis and quantitative data analysis. Qualitative data analysis was conducted by analyzing the results of interviews, observations, and comments or suggestions given to make improvements to the e-LKPD products developed. Quantitative data analysis was conducted by converting quantitative data into qualitative data in the form of certain categories, normality test using shapiro-wilk, t-test with paired samples test, and N-Gain score. The results showed: (1) PBL-based e-LKPDs oriented towards mathematical problem solving skills and self-confidence of high school students on the material of quadratic equations and functions have been produced, (2) PBL-based e-LKPDs developed meet product feasibility, namely valid with excellent categories based on material and media experts; practical with very practical categories based on teacher responses and practical based on student responses; effective on math problem solving skills with classical completeness of 77%, the t-test results obtained a significance value of 0.000 <0.05 which means that there is a difference in the average ability to solve mathematical problems before and after learning using e-LKPD, the N-Gain result is 0.65 with moderate criteria, and effective on student self-confidence with an increase in the average score of each indicator before and after learning,  the N-Gain result is 0.49 with moderate criteria, and the t-test results with a significance value of 0.000 < 0.05.

The topics of morphology, anatomy, and physiology are integral to biology learning, yet they often present challenges for students due to their abstract and complex nature. Difficulties in understanding body structures and invisible biological processes lead to low student interest and engagement. This study aims to identify innovative learning approaches through an analysis of national scientific literature over the past decade. The results show that the integration of digital technology and student-centered learning methods can improve conceptual understanding and learning motivation. The most prominent innovations include the use of VR and AR-based media to clarify visualizations, the use of interactive videos and simulations to explain biological functions, and the application of contextual learning models such as Problem-Based Learning (PBL) and Project-Based Learning (PjBL). These approaches have proven effective in creating a more immersive learning experience that is relevant to students' needs.

In Indonesia, there are approximately 22.97 million people, or approximately 8.5 percent of the population, with the largest proportion being in the elderly group. One form of disability is physical disability, a condition in which limbs are imperfect due to defects that cause damage to bones, muscles, and joints, so that body functions cannot run normally. This condition often impacts not only the physical aspect, but also the psychological health of the sufferer. One of the main challenges faced by people with physical disabilities is maintaining resilience, namely the individual's ability to overcome depression, anxiety, pressure, and stress in living daily life. This study uses a literature review method to examine the results of previous studies relevant to the topic of resilience in people with physical disabilities. The data collection process was carried out through literature searches on the internet using sources from Google Scholar and Google Books. The criteria for selected literature include research that focuses on psychological interventions, especially reality therapy, and its effect on increasing resilience. Reality therapy is a counseling approach that emphasizes personal responsibility, awareness of choices, and the development of skills to face life's challenges effectively. The study results indicate that reality therapy has been shown to have a positive effect on increasing resilience in individuals with physical disabilities. Through a structured counseling process, this therapy helps individuals recognize their potential, develop positive attitudes, and develop adaptive coping strategies. Furthermore, reality therapy can increase motivation, self-confidence, and the ability to make constructive decisions when faced with physical limitations and social pressures. These findings indicate that the application of reality therapy can be an effective approach to supporting the psychological well-being of individuals with physical disabilities, while also contributing to more holistic rehabilitation efforts in Indonesia.

Health problems are a major problem in developing countries, including Indonesia. The Community Health Center (Puskesmas) is a first-level health service facility that organizes and coordinates promotive, preventive, curative, rehabilitative, and/or palliative health services in its working area. The purpose of this study is to understand the function of Puskesmas management in assessing the performance of Puskesmas in the working area of ​​the Mantup Puskesmas. The type of research used is qualitative descriptive research, the location of the study is the Mantup Puskesmas, Mantup District, Lamongan Regency, the informants in this study were the head of the Puskesmas, the person in charge of cluster 1, the person in charge of cluster 2, the person in charge of cluster 3, the person in charge of cluster 4 and the person in charge of cross-cluster Puskesmas Mantup. Data collection was carried out through in-depth interviews, observation and document searches, data analysis techniques using data reduction, data presentation, drawing conclusions. The results of the research for planning at the Mantup Puskesmas have been implemented well. Organizational efforts have been suboptimal, as some sub-health centers only have midwives as regional supervisors. Implementation is suboptimal due to limited staffing at sub-health centers. Supervision at Mantup Health Center has been functioning well and is being implemented regularly, but performance data is not yet available.Timely input into the existing application, considering the large number of applications that must be completed by service officers and program implementers at the Mantup Community Health Center. Suggestions included establishing a regional development team at the Assistant Community Health Center to optimize village activities, advising the Health Office on integrating health service applications at the Community Health Center, and innovations to improve Community Health Center performance.  

This study aims to analyze the application of accounting information systems in cash receipts and expenditures and assess their contribution to the effectiveness of internal control at the Sekoto Putro Showroom in Kediri. The research methodology employed is a qualitative approach, with data gathered through interviews, observations, and documentation. The findings reveal that the current accounting information system is still manual and lacks standard operating procedures (SOPs). The process of cash receipt and disbursement is managed by the finance department under the direct supervision of the owner, who also functions as the primary controller. The owner’s consent is required for all large transactions, and internal control is implemented informally through cash checks and transaction authorizations. However, there are notable weaknesses, including the absence of a clear separation of duties and a lack of a well-documented recording and authorization system. These weaknesses pose risks to the efficiency and reliability of financial management and internal control. Consequently, this study recommends the implementation of a computer-based accounting system, the creation of written SOPs, and a more defined separation of financial duties. Such changes are expected to enhance the effectiveness of internal control, improve operational efficiency, ensure more accurate record-keeping, and minimize the risk of financial losses in showroom cash management. By transitioning to a formalized and computerized system, the showroom can streamline its processes and safeguard its financial resources, ensuring long-term sustainability and growth. This research highlights the need for modernizing accounting practices to foster better financial governance and strengthen internal controls in small to medium-sized businesses.

This study aims to examine the differences and similarities between continental and local Indonesian cuisine, focusing on the case studies of Beef Stroganoff and Rendang. The study covers aspects such as ingredients, cooking techniques, presentation, and the cultural values embedded in these dishes. The research employs a qualitative descriptive case study approach, collecting data through observation, interviews, and literature review. The results indicate that continental cuisine emphasizes the use of high-quality ingredients, often favoring simplicity and freshness, and applies quick cooking techniques such as sautéing or grilling. Presentation is also a key element, with attention to aesthetic appeal and portion control. Beef Stroganoff, for example, is known for its creamy texture and elegant plating. In contrast, local Indonesian cuisine, as exemplified by Rendang, is characterized by its complex spice blends and slow cooking methods, often taking hours to achieve the desired taste and texture. Rendang holds deep social and cultural meanings, commonly served at ceremonial events or traditional gatherings, symbolizing patience, generosity, and respect for tradition. Despite these differences, both types of cuisine share similar functions in society: they both aim to fulfill nutritional needs, express cultural values, and strengthen social bonds. Food, in both contexts, becomes more than just sustenance—it is a form of identity and communication. This study recommends integrating local culinary studies into the culinary education curricula, especially at vocational and higher education levels. By doing so, students not only learn technical skills but also develop an appreciation for the cultural heritage embodied in Indonesian cuisine. This is essential in the era of globalization, where local identities risk being overshadowed by global culinary trends. Preserving and promoting traditional dishes like Rendang is vital for safeguarding Indonesia’s gastronomic identity and fostering pride in national culture.

This study aims to uncover, analyze, and document the cultural values embodied in the paca or belis tradition in Manggarai community weddings in Golo Wangkung Village, Congkar District, East Manggarai Regency. The belis tradition is understood as an important element in wedding customs that symbolizes the groom's family's respect for the bride's family for their services in raising and educating their daughter until she is ready to start a household. This study uses a qualitative approach with descriptive methods, utilizing data collection techniques through participatory observation, in-depth interviews with traditional leaders, the bridal couple, and local residents, as well as documentation of the traditional procession. The results show that belis not only contains economic value through the provision of material or livestock, but is also full of social, cultural, and spiritual meaning. The main values identified include respect for parents and ancestors, the responsibility of the groom's family for the continuity of family relationships, strengthening social ties between two extended families, and a symbol of the legitimacy of marriage according to Manggarai customs. The belis tradition also functions as a mechanism to maintain harmonious relationships between families and strengthen social networks within the community. Furthermore, this tradition plays a strategic role in maintaining local cultural identity amidst modernization and changing social values. However, challenges arise when the economic value of belis experiences inflation or a shift in meaning, potentially triggering financial burdens and conflict. Therefore, preserving the belis tradition requires adjustments to its values and implementation mechanisms to maintain its relevance, without losing the essence of respect and togetherness that are at the heart of Manggarai culture. This research makes an important contribution to the documentation and preservation of cultural heritage, and serves as a reference for local governments, traditional leaders, and the community in maintaining the sustainability of the paca or belis tradition.

This study examines the practice of reciprocity within the persatuan barang (goods-sharing) group during the implementation of the rewang tradition in Desa Banglas, Kecamatan Tebing Tinggi, Kabupaten Kepulauan Meranti. The main focus of the research is to identify the various forms of exchange that occur, whether in the form of money, goods, or labor. A narrative qualitative approach was used, with data collected through in-depth interviews, non-participant observation, archival review, and documentation of bookkeeping records. The subjects of this research are members of the persatuan barang group who actively participate in social and cultural events in the village. The findings reveal three types of reciprocity: generalized, balanced, and negative. Generalized reciprocity is evident in voluntary contributions without expecting immediate return, often practiced among close kin or neighbors. Balanced reciprocity is demonstrated through exchanges of equal value with a certain expectation of timely return, particularly during communal events like weddings or funerals. Negative reciprocity, although rare, involves unequal exchanges that may lead to social tensions or perceptions of unfairness. These findings indicate that the persatuan barang group functions not only as an informal economic mechanism but also as a cultural institution that fosters mutual assistance, reinforces social cohesion, and preserves traditional values. The exchange systems operate within an implicit moral economy that prioritizes collective welfare over individual gain. Additionally, the tradition of rewang and the organizational role of persatuan barang highlight the resilience and adaptability of indigenous practices in supporting rural livelihoods amid changing socioeconomic conditions. The study suggests that such local systems of reciprocity play a vital role in sustaining social capital, strengthening community identity, and ensuring social security in the absence of formal welfare structures. Further research is recommended to explore the long-term impact of these practices on community resilience and rural development.  

The management of blood glucose levels in individuals diagnosed with diabetes mellitus is a multifaceted process that involves the integration of pharmacological therapy and evidence-based nutritional interventions. Among these strategies, nutritional therapy plays a pivotal role in achieving optimal glycemic control and preventing diabetes-related complications. The success of nutritional therapy is closely tied to the individual’s adherence to prescribed dietary guidelines and the ability to meet adequate protein intake as recommended by healthcare providers. Protein is essential not only for maintaining muscle mass and supporting metabolic functions but also for its role in stabilizing blood glucose levels through slower glucose absorption and enhanced satiety. This study was conducted to investigate the relationship between dietary adherence and adequate protein intake with fasting blood glucose (FBG) levels among outpatients diagnosed with type 2 diabetes mellitus at RSUD dr. Iskak Tulungagung. A quantitative research method with a cross-sectional design was employed, involving 26 respondents selected using a non-probability sampling technique. Data collection utilized structured questionnaires to assess dietary compliance, interview forms to capture dietary behavior and protein intake patterns, and medical record documentation to obtain accurate FBG measurements. Statistical analyses included Pearson correlation tests for normally distributed data and Spearman rho tests for non-normally distributed data, ensuring appropriate analytical rigor. The results indicated a significant negative correlation between both dietary adherence and adequate protein intake with fasting blood glucose levels. This finding suggests that individuals who consistently follow dietary recommendations and consume sufficient protein tend to exhibit lower FBG values, indicating better glycemic control. Such results underscore the importance of not only emphasizing dietary compliance but also ensuring protein adequacy in daily nutritional plans for type 2 diabetes patients. These findings have practical implications for diabetes management programs, highlighting the necessity of sustained patient education, regular counseling, and individualized meal planning.
