This study aims to examine in depth the effectiveness of the application of the Children Learning in Science (CLIS) learning model in the Natural Science (Science) learning process. The background of this study stems from the problem of low active student participation in class, which is largely caused by difficulties in understanding abstract science concepts. The CLIS model offers a learning approach that emphasizes active student involvement through a series of systematic learning stages. The method used is a literature review with a qualitative descriptive approach. Analysis was conducted on 25 articles from national and international publications. Each article was reviewed based on relevance, research methods, main findings, and the suitability of CLIS application in various science learning contexts. The results of the study indicate that CLIS has proven effective in improving students' understanding of science concepts, developing science process skills such as observation, classification, measurement, and hypothesis testing, and encouraging active student participation during the learning process. In addition, this model is also able to improve critical thinking skills through exploration activities, experiments, group discussions, and reflection on learning outcomes. The CLIS stages, which include exploring students' prior knowledge, introducing new concepts through experiments, strengthening understanding through discussions, and strengthening concepts through reflection, enable students to construct knowledge independently and meaningfully. Based on these findings, CLIS is considered relevant and can be an effective alternative learning model to improve the quality of science learning at various levels of education.

This study aims to empirically examine the influence of the Internal Control System (SPI), Regional Financial Accounting System (SAKD), Government Accounting Standards (SAP), and Transparency on the quality of financial statements in the Regional Government of Purbalingga Regency. The problem of the quality of financial statements is still an important issue in regional financial management, because quality financial reports not only function as a form of accountability to the public, but also as a basis for strategic decision-making for local governments. The research method uses a quantitative approach with questionnaire instruments distributed to 61 respondents, consisting of local government officials involved in the process of preparing financial statements and have met the research criteria. Data analysis was carried out using the inner model and outer model approaches, which resulted in an R-square value of 0.743 for the financial report quality variable. This value shows that the independent variables in this study were able to explain 74.3% of the variation in the quality of financial statements, while the rest was influenced by other factors outside the research model. The results of the analysis show that the SAKD and Transparency variables have a significant influence on the quality of local government financial statements. This confirms that a good financial accounting system and transparency in public budget management are the main factors that can improve the reliability, relevance, and accountability of financial statements. On the other hand, the SPI and SAP variables did not have a significant effect, which shows that the implementation of both still needs evaluation and improvement in order to make a real contribution to the quality of financial statements.

This study explores the influence of information system quality, information technology sophistication, and personal technical capability on the effectiveness of Accounting Information Systems (AIS) in Village Credit Institutions (LPDs) in Jembrana Regency. The research adopts a quantitative approach, utilizing a survey method. Questionnaires were distributed to 63 employees from 21 LPDs that have already implemented computerized AIS. The study focuses on assessing how these three independent variables contribute to the effectiveness of AIS in the LPDs. Multiple linear regression was employed for data analysis, allowing the researcher to determine the relationship between the independent variables and the effectiveness of AIS. The respondents were selected from LPDs that had successfully integrated technology into their accounting systems. The primary objective was to understand whether system quality, IT sophistication, and personal technical capability played a significant role in improving AIS performance in these institutions. The findings of the study indicate that all three independent variables—system quality, IT sophistication, and personal technical capability—positively influence the effectiveness of AIS. Specifically, high-quality systems, advanced IT infrastructure, and employees with strong technical skills were found to enhance the operational effectiveness of AIS. This underscores the importance of these factors in ensuring the smooth functioning of AIS in LPDs. As such, LPDs are encouraged to invest in improving system quality, upgrading IT systems, and enhancing the technical skills of their staff to optimize AIS performance. Overall, the study contributes to the understanding of how technological factors can be leveraged to improve accounting processes in financial institutions, particularly in rural settings like LPDs in Jembrana Regency.

This research is motivated by the fluctuation in the level of motor vehicle taxpayer compliance in Nganjuk Regency, which raises the need to evaluate the factors that influence it. Tax knowledge, quality of tax services, and service modernization through the e-Samsat system are considered important variables in improving compliance. In addition, taxpayer awareness is expected to strengthen the influence of these variables. The main objective of this study is to analyze the influence of tax knowledge, service quality, and e-Samsat system modernization on taxpayer compliance, by placing taxpayer awareness as a moderating variable. This study uses a quantitative approach with a causal-comparative research type. Data collection was carried out by distributing questionnaires to 100 respondents selected using a purposive sampling technique. The data analysis method used is Moderated Regression Analysis (MRA) with the help of SPSS software version 27. The results of the study indicate that tax knowledge has a significant influence on taxpayer compliance. In contrast, the quality of tax services and e-Samsat modernization do not have a significant influence on compliance. Furthermore, taxpayer awareness was shown to significantly moderate the relationship between tax knowledge and compliance, but did not act as a moderator in the relationship between service quality or e-Samsat system modernization and taxpayer compliance. This finding indicates that increasing taxpayer awareness can strengthen the effectiveness of tax education. However, administrative and digital approaches cannot optimally increase compliance without being accompanied by stronger awareness among taxpayers themselves.

This study aims to analyze the impact of internal control systems and service quality on accountability and work culture at LP3I Banda Aceh. Specifically, it investigates how internal control systems influence accountability and work culture, as well as the effect of service quality on both accountability and work culture. Additionally, the research explores the role of work culture as a moderating variable in the relationship between internal control systems, service quality, and accountability. The study involves two exogenous variables, namely internal control systems and service quality, and one endogenous variable, accountability. Work culture is treated as a moderating variable. The research population includes employees and lecturers at LP3I Banda Aceh, with a total of 53 respondents in the sample. The analysis was conducted using Structural Equation Modeling (SEM) with PLS 3.0 software. The findings reveal that both internal control systems and service quality partially affect accountability and work culture. More specifically, internal control systems have a positive effect on accountability, indicating that effective internal controls contribute to higher levels of accountability within the institution. Likewise, service quality also influences accountability, suggesting that improving the quality of services leads to better accountability outcomes. Furthermore, work culture is shown to have a significant impact on accountability, reinforcing the idea that a positive work culture fosters higher levels of accountability.

This indicates that a strong work culture can amplify the positive effects of internal control systems and service quality on accountability, contributing to the overall effectiveness of the institution.

This community service activity was motivated by the need for an efficient and structured library management system at MI Hidayatul Ulum. Previously, book recording, borrowing, and reporting were done manually, creating administrative challenges and limiting access to information for students and teachers. To address these challenges, the community service team implemented a web-based library information system designed to simplify collection management, facilitate book searches, and expedite the borrowing and return process. The implementation method included partner needs analysis, system design and installation, training for staff and teachers, and evaluation of implementation results. The system was designed to be accessible through the school's local network with a simple and user-friendly interface. Training was provided to ensure the school was able to utilize and manage the system independently. The results showed that the implementation of this information system improved library management efficiency and expanded user access to information. Teachers could more easily monitor book collections, while students found it easier to search for and borrow books. Furthermore, the system accelerated administrative processes and reduced the risk of recording errors. Another positive impact was the growth of a technology-based literacy culture within the madrasah. With the availability of faster book search and borrowing services, students' interest in reading increased. A participatory approach involving schools from the planning stage through evaluation ensures that the resulting solutions meet needs and can be implemented sustainably. This community service activity is expected to serve as a model for implementing simple technology that has a real impact on improving the quality of basic education services.

Slum settlements developing around Final Disposal Sites (TPA) represent a complex phenomenon that affects the quality of the urban living environment. In Karo Regency, the proximity of the TPA to residential areas has raised various issues such as air pollution, declining sanitation quality, and limited community participation in spatial planning processes. This study aims to analyze the influence of Distance to the TPA (X1), Length of Residence (X2), Community Participation (X3), Perception of TPA Impact (X4), and Household Income (X5) on the Quality of Slum Settlements (Y). A quantitative approach was applied using a multiple linear regression model, based on primary data from 200 respondents residing in areas affected by the TPA. The analysis revealed that, simultaneously, the four independent variables (X1–X4) significantly influence settlement quality, whereas household income does not show a significant effect. Partially, Distance to the TPA and Length of Residence have negative effects, while Perception of TPA Impact has a positive effect. Interestingly, Community Participation shows a negative influence, indicating ineffective engagement in environmental management. The R² value of 0.016 suggests that the model explains only a small portion of the variation, yet the F-test significance supports the overall model's relevance. Recommendations from this study include the importance of establishing a minimum 300-meter buffer zone between the TPA and residential areas, implementing sanitary landfill methods to replace open dumping systems, forming environmentally-based community forums with advocacy strength, and conducting community-based waste management training focusing on high-risk households. Strengthening participatory approaches through integration into village and sub-district spatial planning is essential for managing environmental impacts collaboratively and sustainably.

The digital era has revolutionized educational systems, making digital literacy a vital competency for the 21st century. As such, educational administration plays a pivotal role in driving digital transformation within schools. This study used a qualitative approach with a multi-case study design, examining 20 secondary schools to assess how effective educational administration practices contribute to the sustainable implementation of digital literacy programs. Data were gathered through in-depth interviews with 60 educational administrators, participant observations, and the analysis of policy documents. The findings reveal that educational administration, when proactive, collaborative, and data-driven, significantly boosts student digital literacy. In fact, schools employing these practices experienced an improvement in digital literacy by up to 65% within two years of program implementation. The success of these programs was largely attributed to key factors such as visionary leadership, strategic allocation of resources, continuous teacher capacity development, and robust monitoring systems. Additionally, the research highlights the importance of a comprehensive approach to digital literacy, where educational leaders understand the interconnections between various administrative functions and their impact on digital education. This includes integrating strategic planning, operational execution, developmental efforts, evaluation processes, and collaborative work between teachers and administrators. In response to these findings, the study proposes the Integrated Digital Literacy Administration Model (MALDT). This model offers a framework that can be adapted by educational institutions to enhance learning quality in the digital age. It emphasizes the need for a holistic approach to digital literacy administration, combining leadership vision with operational efficiency and continuous professional development. Ultimately, the adoption of such a model can help schools foster an environment where digital literacy is embedded into the core educational experience, ensuring students are adequately prepared for the challenges of the digital era.

This community service initiative aims to educate and assist in the implementation of an Internal Control System ICS at Minimarket Malika as a strategic effort to safeguard assets and enhance operational effectiveness and efficiency. The ICS applied includes a systematic recording process for inventory, purchase prices, and selling prices. These records are intended to ensure that all transactions are properly documented and accountable.Internal evaluations are conducted regularly through annual stock-taking activities, which involve verifying and matching inventory data recorded in the system with the actual physical stock in the store or warehouse. This activity serves as a critical benchmark for assessing business stability, the accuracy of inventory records, and the overall effectiveness of inventory management. Any transactional errors identified during sales operations are corrected immediately in real-time to prevent error accumulation and potential financial losses. The role of management is essential, particularly in maintaining business continuity through improved service quality and the timely fulfillment of customer needs. In response to intense competition and dynamic market changes, Minimarket Malika adopts adaptive strategies such as price adjustments, excellent customer service, and a broader product assortment to meet diverse consumer demands. To prevent fraud, the minimarket has installed CCTV cameras at strategic locations and provides training for employees on how to detect counterfeit money and suspicious behavior. The ICS also supports risk management in inventory by monitoring the movement of goods in real-time, allowing management to make accurate decisions about which products need to be stocked in accordance with current consumer demand trends.Through the consistent and comprehensive application of an internal control system, Minimarket Malika is expected to improve its competitiveness while maintaining the integrity and sustainability of its business operations amid ongoing economic challenges.

Pharmacist professionalism is a key component in ensuring the quality of pharmaceutical services, encompassing not only compliance with technical and scientific standards but also a deep commitment to moral and ethical principles. In the Indonesian cultural context, the concept of "medicine as a trust" (obat sebagai amanah) reflects a profound sense of responsibility, where medicine is viewed not merely as a commodity, but as a mandate that must be preserved with integrity and accountability in health care practices. This article conceptually explores the relationship between pharmacist professionalism and the moral value of trust within the framework of the Nusantara constitutional theory. This theory emphasizes the integration of legal, cultural, and moral dimensions in shaping professional conduct in Indonesia. Using a descriptive-critical approach through literature review, this study investigates how trust functions as both a legal expectation and a cultural imperative in the practice of pharmacy. The findings highlight that trust must be internalized as a core value in pharmaceutical services—manifested through ethical decision-making, transparency in drug management, and a commitment to prioritizing patient welfare. Pharmacists are not only required to uphold professional standards, but also to carry out their duties as custodians of public trust. To realize this vision, the integration of the value of trust into pharmacy education, legal regulations, and clinical practice is essential. Educational institutions, professional organizations, and regulatory bodies must work collaboratively to instill this value as part of a pharmacist’s identity. In doing so, the profession can contribute more effectively to building a health care system that is just, culturally grounded, and centered on the well-being of the people.

Infant growth and development are crucial issues that require serious attention, particularly during the early childhood phase, which is crucial for a child's future development. The golden age of infants is the most sensitive period to various forms of stimulation that influence their motor, sensory, cognitive, and emotional development. However, not all parents, especially mothers, fully understand the importance of appropriate and safe stimulation in supporting infant growth and development. One form of stimulation that is relatively easy to perform, has no side effects, and can be applied independently at home is gentle touch therapy. Gentle Touch Therapy is a complementary therapy method that involves gentle, affectionate touch on the baby's body, aimed at stimulating the nervous system, strengthening the emotional bond between mother and child, and increasing comfort and relaxation in the baby. Several studies have shown that this gentle touch can improve sleep quality, accelerate weight gain, relieve stress, and encourage infant neuromotor and socio-emotional development. This community service activity was carried out as an effort to increase mothers' awareness and skills in providing stimulation through gentle touch. The activity was carried out at the Andina Independent Midwife Practice (PMB), Palembang City, in June 2025. The main target of this activity was mothers with babies aged 0–12 months. The implementation method included providing education through interactive lectures, demonstrations of touch therapy techniques by health professionals, and direct practice by mothers accompanied by facilitators. The results of the activity showed a significant increase in mothers' understanding of the importance of growth and development stimulation, especially through gentle touch therapy. The participants showed high enthusiasm in participating in the activity and were able to practice gentle touch techniques correctly and confidently.

This study aims to explain and analyze the quality of public services at the Leihitu Barat District Office. Quality public service is a key indicator in assessing the performance of local governments, particularly at the sub-district level, which directly provides services to the community. This research uses a descriptive method with a qualitative approach to gain an in-depth understanding of the current service conditions. The informants in this study totaled 10 people, consisting of district officials and community members who use the services. Data were collected through in-depth interviews, observations of service activities at the sub-district office, and documentation of relevant supporting documents. The collected data were analyzed using descriptive qualitative analysis with a case study approach, providing a comprehensive picture of existing problems and potentials. The assessment of service quality is based on Zeithaml’s theory, which includes five main dimensions: tangibles, reliability, responsiveness, assurance, and empathy. The research findings indicate that the quality of public services at the Leihitu Barat District Office has not yet met optimal standards. In terms of tangibles, it was found that physical facilities such as waiting areas, service desks, and supporting equipment are still very limited. The reliability dimension is also not well fulfilled, as the service processes are often inconsistent and not timely. The assurance dimension reflects a lack of professional ability and attitudes among officials in providing a sense of security and trust to the public. However, the dimensions of responsiveness and empathy show relatively positive developments. Some officials have demonstrated responsive and empathetic attitudes in addressing the needs and complaints of the public. Nonetheless, comprehensive improvements are still necessary. These include enhancing the quality of human resources, increasing the availability of physical infrastructure, and improving service management systems. By addressing these areas, public services at the Leihitu Barat District Office can become more effective and better aligned with community expectations.

This study aims to analyze the influence of the lifestyle of credit relationship managers (RMs) and the potential for fraud on the occurrence of non-performing loans in the banking sector. Relationship managers are the spearheads of credit distribution, interacting directly with customers, so their behavior, lifestyle, and integrity have a significant impact on the quality of a bank's credit portfolio. This study uses a qualitative descriptive method with a systematic literature review approach, reviewing various recent studies related to bank employee lifestyles, factors driving fraud, and their correlation with non-performing loans. The results indicate that a consumptive lifestyle disproportionate to income can increase the risk of fraudulent behavior, such as manipulation of credit analysis or collusion with customers, which ultimately results in an increase in non-performing loans. Furthermore, weak internal control systems, pressure to achieve credit targets, and moral hazard exacerbate this risk. A lifestyle that prioritizes social symbols and self-image can also encourage employees to engage in deviant behavior to maintain this lifestyle. Several studies have shown that RMs trapped in a hedonistic lifestyle are more vulnerable to conflicts of interest and violations of professional ethics. Meanwhile, the potential for fraud in banking practices is also influenced by employees' weak personal financial literacy, as well as limited training in risk management and ongoing work ethics. In an organizational context, a work culture oriented toward achieving targets without regard for the quality of credit analysis has the potential to create a work climate that is permissive of irregularities. This study recommends strengthening a culture of integrity through the establishment of a firm code of ethics, technology-based supervision (such as an AI-based fraud detection system), and regular training on a healthy financial lifestyle and risk management for RMs.

This research employs a qualitative approach with a case study design, involving data collection through in-depth interviews, observations, and analysis of policy-related documents. The findings reveal that the implementation of Kampus Merdeka during the pandemic has encouraged increased student creativity, interdisciplinary collaboration, and more contextual learning experiences beyond the classroom. The policy also provides opportunities for students to develop their potential in a more flexible and adaptive manner. This study concludes that Kampus Merdeka, as a government policy, holds significant potential in shaping a higher education system that is more relevant and resilient to changing times, particularly in the context of a global crisis.

In the academic world, proper and efficient reference management is essential to ensure the quality and credibility of scientific writing. However, many lecturers and education practitioners, particularly early childhood education teachers, still encounter difficulties in managing references according to established academic standards such as APA and MLA citation styles. This challenge often hinders the process of academic writing and decreases the quality of scholarly outputs. To address this issue, a structured training program was conducted focusing on the use of Mendeley, a digital reference management tool designed to simplify citation and bibliography management automatically. The objective of this training was to enhance participants’ technical competence, digital literacy, and their ability to integrate Mendeley into the process of preparing scientific papers. The training activities were carried out using a series of steps, including needs assessment of participants, collaborative planning, hybrid training implementation (both online and offline), and continuous assistance through follow-up forums. Throughout the program, participants were guided step-by-step on how to install, use, and integrate Mendeley into word processing applications for academic writing. The results of the evaluation showed a significant increase in participants' knowledge and practical skills, with an N-Gain score of 0.70, which falls into the high effectiveness category. The training not only improved the quality of reference management in scientific papers but also promoted greater professionalism and academic accountability. Moreover, it supported the broader goal of integrating technology into educational development. Overall, this initiative is expected to encourage more systematic, efficient, and digitally literate practices in academic writing among educators, ultimately contributing to improved educational quality in higher education settings.

This study aims to understand, review, explore, and describe the implementation of policies regarding the enforcement of teacher and student discipline in elementary schools and is expected to find policies that support the success of enforcing teacher and student discipline. This study was conducted using a Systematic Literature Review (SLR) in journals that are appropriate for Elementary Schools, subjects consisting of principals, teachers, educational staff, and students. Data in this study were obtained through Identification of Literature Sources, Determination of Inclusion and Exclusion Criteria, Tools (Mendeley). The findings of the study conducted by the author indicate that the enforcement of teacher and student discipline is carried out through a number of policies, namely: 1) Policies related to the enforcement of teacher and student discipline, 2) Establishing rules at school and in the classroom, 3) Monitoring the disciplinary behavior of teachers and students by making a monitoring book of their daily activities, 4) Imposing sanctions for violations, 5) Involving the principal, teachers, and educational staff. Furthermore, parental involvement and collaboration with external parties are also supporting factors in creating an orderly, safe, and conducive learning environment. Regular evaluation of implemented policies is also crucial to ensure their relevance and effectiveness. Fair and transparent reward and punishment practices contribute to increased student awareness and motivation to comply with school regulations. A culture of discipline consistently cultivated from an early age significantly contributes to positive character development and the overall improvement of the quality of basic education. Implementation requires ongoing training and mentoring for teachers and other educational staff to equip them with the capacity to implement a humanistic yet firm approach.

Tuberculosis (TB) is an infectious disease caused by infection with bacteria from the Mycobacterium tuberculosis complex group. TB prevention efforts are crucial, especially for individuals at high risk of exposure, to disrupt the chain of transmission of this disease. The intervention aimed to increase community understanding of TOSS TB (Find, Treat, Treat Until Cured) so that it can be applied in daily life. It is expected that after the intervention, participants' knowledge will increase, as will their ability to demonstrate the practices taught appropriately. Data collection was conducted through a mini-survey of the community in the local Community Health Center (Puskesmas) working area. The data obtained were then analyzed using the Blum Paradigm to identify factors contributing to the problem. Problem prioritization was carried out using the non-scoring Delphi method, while root cause analysis was conducted using a fishbone diagram. During the intervention process, pre- and post-tests were conducted to evaluate changes in the level of knowledge of villagers before and after the intervention. For program monitoring and evaluation, the PDCA (Plan-Do-Check-Act) cycle approach and a systems approach were used. The analysis using the Blum Paradigm showed that lifestyle was the primary contributing factor to the problem. After the intervention, three participants were able to repeat the material effectively, demonstrating a better understanding of TB prevention. Based on these results, it can be concluded that the intervention was successful and is expected to encourage improvements in public health in the village. Furthermore, this program is also expected to serve as a model for other public health interventions, thereby expanding the positive impact of TB control efforts in other areas. Thus, public awareness and knowledge about TB can continue to increase, which in turn will contribute to reducing TB incidence in Indonesia and improving the overall quality of life of the community.

Indonesia, as the country with the largest Muslim population in the world, has a significant demand for halal products, including pharmaceuticals. Halal certification serves not only as a regulatory compliance requirement but also as a strategic tool to build consumer trust, ensuring that products meet both religious and quality standards. This article aims to descriptively examine the process and challenges of preparing for halal certification in the pharmaceutical industry, focusing on the evaluation of active pharmaceutical ingredients (APIs) and excipients. The study is based on firsthand experience during a pharmacist professional practice (PKPA) at a national pharmaceutical company. Key areas of focus include material flowchart analysis, identification of critical non-halal points, and the implementation of the Halal Product Assurance System SJPH, in line with Indonesian halal regulatory frameworks. The findings highlight the importance of systematically identifying critical points, especially in evaluating the origin and status of materials such as alcohol, enzymes, and activated carbon, which frequently raise concerns in halal compliance. Furthermore, successful implementation requires comprehensive documentation, revision of standard operating procedures (SOPs), and staff training to ensure traceability and consistency throughout the supply chain. Collaboration with the Indonesian Ulema Council (MUI) and the Halal Product Assurance Organizing Agency (BPJPH) is also vital for technical guidance and certification processes. The study concludes that a structured and integrated approach to halal assurance not only facilitates certification but also enhances operational quality and market competitiveness. This study is expected to provide practical insights for pharmaceutical industries in effectively and sustainably implementing halal regulations, contributing to broader consumer protection and industry accountability.

Reverse engineering is the process of reproducing or recreating an existing model—whether it is a component, subassembly, or complete product—without relying on the original design documentation or CAD data. One of the key techniques that supports this process is photogrammetry, a method that utilizes a series of photographic images to identify, capture, and reconstruct the geometry of physical objects in three dimensions. Photogrammetry offers advantages such as low cost, portability, and non-contact data acquisition, making it a valuable tool in various engineering and industrial applications. This study aims to analyze the influence of two important factors—namely, the number of photographs taken and the intensity of lighting—on the dimensional accuracy or deviation of 3D models produced through photogrammetry-based reverse engineering. A quantitative experimental approach was used, where both variables were systematically varied to evaluate their effect on model precision. Data analysis was conducted using a Two-Way ANOVA factorial test to determine the statistical significance of each factor and their interaction. The experimental results revealed that using 54 photographs yielded the lowest average dimensional deviation among all tested conditions, although the difference was not statistically significant. Similarly, variations in light intensity showed no statistically significant effect on accuracy, but visually, an illumination level of 200–250 lux tended to provide more consistent and stable model outputs. No significant interaction was found between the two variables, indicating that they operate independently in affecting model accuracy. Overall, the combination of 54 photographs and a light intensity of 250 lux was visually identified as the most effective setup. The findings of this research contribute to the optimization of photogrammetry workflows in reverse engineering, offering practical insights for producing high-quality CAD models for use in design, prototyping, and manufacturing processes.
