This study examines the effectiveness of implementing a democratic classroom management model in enhancing student learning motivation at Jambu Public Elementary School 3. A descriptive qualitative approach was employed, with data collected through direct classroom observations and interviews involving teachers and students. The aim was to understand how democratic principles applied in classroom settings could influence students’ motivation, behavior, and engagement in learning activities. The findings reveal that adopting democratic leadership in classroom management creates an inclusive, respectful, and participatory learning environment. Students are encouraged to express opinions, collaborate in decision-making, and take ownership of their learning process. This approach significantly enhances intrinsic motivation, responsibility, and student independence. It also helps reduce passive behavior and fosters a sense of belonging and self-worth among students. The results are in line with several prominent educational theories. According to Self-Determination Theory (Deci & Ryan), autonomy and relatedness are key drivers of motivation, which are facilitated through democratic practices. Vygotsky’s Social Development Theory emphasizes the role of social interaction in learning, which is actively promoted in this model. Carl Rogers’ humanistic approach also supports the creation of a learning climate centered on empathy and student potential, while Rudolf Dreikurs’ Adlerian classroom model advocates for respectful teacher-student relationships and cooperative behavior. Overall, the implementation of a democratic classroom management model is considered effective in promoting both academic achievement and character development at the elementary level. The study recommends broader application of this model in primary education settings to support holistic student growth and to foster a learning culture rooted in mutual respect, responsibility, and student agency.  

Tempoyak is a traditional Indonesian fermented food made from the flesh of durian (Durio zibethinus Murr.), which undergoes spontaneous fermentation driven by indigenous microorganisms. The fermentation process generally occurs under anaerobic conditions and is primarily dominated by lactic acid bacteria (LAB), including species such as Lactobacillus, Leuconostoc, and Pediococcus. These bacteria play a crucial role in modifying the physicochemical properties of the product, including a significant reduction in pH, an increase in the concentration of organic acids, and the formation of volatile compounds responsible for tempoyak’s distinctive aroma and overall flavor complexity. In addition to enhancing its unique sensory profile, the fermentation process also extends the shelf life and introduces probiotic potential to the final product. This study aims to observe and analyze the microbiological and chemical aspects of tempoyak fermentation and to evaluate its potential as a local functional food with health-promoting properties. Laboratory tests and microbial analyses confirmed that the fermentation process not only retains essential nutrients but also promotes the growth of beneficial bacteria, provided the production conditions are hygienically maintained at all stages. The study emphasizes the importance of controlled fermentation techniques to ensure product safety and consistent quality. Furthermore, the findings reveal that tempoyak could serve as a promising probiotic-rich food that supports digestive health, contributing to the diversification of traditional Indonesian fermented foods. With its appealing flavor, cultural value, growing consumer interest, and potential health benefits, tempoyak holds significant promise for future development and commercialization, particularly in the field of functional food innovation rooted in indigenous culinary practices.

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.

Advances in information technology-based financial services are beginning to follow suit, in the form of peer-to-peer lending, which provides easy access to loans without the need for conventional financial institutions. However, this convenience brings new challenges, particularly regarding the protection of users' personal data. Many platform providers access excessive amounts of sensitive information, such as contacts, photos, and other personal data, which can be misused to the detriment of borrowers. Therefore, this study aims to identify and analyze regulations related to personal data protection, particularly in the field of peer-to-peer lending services in Indonesia. It also analyzes the role of financial institutions, namely the Financial Services Authority (OJK), in addressing potential violations committed by platform providers. Using a normative legal approach, the study shows that despite the existence of these regulations, implementation in the field is suboptimal, particularly in terms of monitoring illegal platforms. Furthermore, challenges to oversight include limited resources and a lack of digital literacy among the public, which results in many users not fully understanding the risks of sharing their personal data. This study also highlights the importance of collaboration between the OJK, the Ministry of Communication and Information Technology, and law enforcement agencies to strengthen oversight mechanisms and take action against violations. In addition, extensive public education regarding personal data security is needed to encourage greater vigilance in using digital services. Personal data protection must be a top priority in the development of financial technology to prevent privacy violations. Strict regulations and effective sanctions are expected to provide a deterrent effect and create a healthy and equitable fintech ecosystem in Indonesia. This study also recommends that the government accelerate harmonization between the Personal Data Protection Law (PDP Law) and financial services sector regulations, particularly regarding service providers' transparency obligations in managing consumer data.  

Cyberattacks on critical infrastructure have become a major challenge in the era of global digitalization. The problem formulation in this study is how international law is applied to address cyberattacks on critical infrastructure in Indonesia, what challenges Indonesia faces in enforcing international law regarding cyberattacks on critical infrastructure, and what efforts are made to overcome these challenges in enforcing international law related to cyberattacks on critical infrastructure in Indonesia. The research method used in this study is normative legal research. The research results show that the enforcement of international law against cyberattacks on critical infrastructure in Indonesia faces significant challenges, such as unclear regulations, issues of state sovereignty, and disagreements between countries. Although Indonesia has participated in international initiatives such as the Budapest Convention and UNGGE, the international law enforcement mechanism is still ineffective in addressing cross-border cyberattacks. Indonesia's domestic law, such as the ITE Law, is still limited in dealing with threats from abroad. Therefore, closer international cooperation, updating domestic policies, and strengthening domestic legal and technological capacities are necessary to ensure more effective and responsive protection against cyber threats.

This study aims to analyze the efforts made by the Sukabumi City Civil Service Police Unit (Satpol PP) in enforcing Mayor Regulation Number 05 of 2014 concerning restrictions on the operating hours of night entertainment venues. The regulation was implemented to maintain public order, reduce social disturbances, and ensure community comfort, particularly during nighttime hours in urban environments. Using a sociological legal approach with qualitative methods, data were collected through interviews with relevant stakeholders, field observations, and literature reviews. The findings reveal that Satpol PP has undertaken various enforcement efforts, including routine patrols to monitor venue compliance, educational outreach to business owners regarding regulations, and administrative sanctions such as written warnings and temporary closures for violators. Despite these initiatives, several challenges hinder the optimal enforcement of the regulation. These include limited human resources and operational infrastructure within Satpol PP, inconsistent public awareness of the regulation, and resistance from certain business actors who view the regulation as a barrier to economic activity and local tourism development. Moreover, coordination between relevant agencies, such as tourism and licensing departments, remains suboptimal. This study emphasizes the need for stronger inter-agency synergy, increased budget allocation, and ongoing public education to foster better compliance. It also suggests capacity-building programs for enforcement officers and the implementation of community-based monitoring systems to enhance transparency and support. In conclusion, although Satpol PP has shown commitment to implementing the regulation, the effectiveness of enforcement can be significantly improved through strategic resource optimization, cross-sector collaboration, and a participatory approach involving both authorities and the community.

The Korean drama True Beauty portrays a vivid reflection of the social reality where beauty standards significantly influence how women are treated in society. This study investigates how these standards lead to discrimination against individuals who do not align with socially constructed ideals of appearance. Specifically, it focuses on the representation of such discrimination in the character of Im Ju Kyung, a high school student who is constantly judged for her natural look. Utilizing a qualitative approach with Roland Barthes' semiotic theory, this research deciphers three levels of meaning—denotative, connotative, and mythological—embedded within selected scenes from episodes 1 and 3. The findings indicate that Ju Kyung encounters six distinct forms of appearance-based discrimination: verbal bullying, physical bullying, non-verbal bullying (such as gestures or facial expressions), social exclusion, beauty privilege (where attractive individuals receive favorable treatment), and internalized social pressure to conform. Each discriminatory act is not only rooted in visual representations but also carries deeper ideological implications—suggesting that physical beauty is a prerequisite for social acceptance and personal value. Although True Beauty critiques the culture of appearance-based discrimination, it simultaneously perpetuates the myth that transformation through makeup or cosmetic procedures is a viable solution to gain acceptance. This duality reflects the complex role of media as both a mirror of societal norms and a tool that reinforces dominant ideologies. In doing so, the drama raises critical questions about the ethical responsibilities of popular culture in shaping perceptions of gender, identity, and worth based on physical appearance. Through this analysis, the study contributes to discussions on media literacy and body politics in contemporary Korean pop culture.

This study explores the meaning of love and courage in the lyrics of Nadin Amizah's song "Taruh". Music serves as a cultural medium that reflects the construction of social reality, and song lyrics often become a space for expressing personal and collective experiences. The song "Taruh" illustrates the emotional complexity present in human relationships, particularly in interpreting the feelings of love intertwined with acts of bravery. This research employs Ferdinand de Saussure's semiotic theory by examining the syntagmatic and paradigmatic relations within the song's lyrics. The descriptive qualitative method is applied, with data obtained through non-participant observation and literature study. The findings indicate that the lyrics of "Taruh" do not portray an idealized version of love; instead, they express a more realistic view of love as something that includes pain, vulnerability, and imperfection. Interestingly, within those imperfections, there is a profound sense of courage—a willingness to endure, to remain, and to accept wounds as a part of emotional life. The syntagmatic analysis highlights how the arrangement of words in each stanza reflects stages of emotional struggle, longing, acceptance, and resilience. On the other hand, the paradigmatic analysis reveals that while alternative words could have been chosen, the selected diction intensifies the emotional nuance without shifting the central message of the narrative. Overall, the song constructs a layered narrative of love, where courage is found not in grand gestures but in silent endurance. This study shows how popular music, through its poetic structure, can communicate complex emotional truths and contribute to deeper cultural understandings of human emotion.

Micro,Small, and Medium Enterprises (MSMEs) are a vital pillar of the national economy, significantly contributing to employment, innovation, and regional economic development. However, in the ever-evolving digital era, many MSMEs have yet to optimally utilize digital promotional technologies and trends, leading to limited market reach and business growth. This community service activity aims to improve MSMEs' understanding and skills in building and developing their businesses through digital-based promotional strategies. The methods used in this activity include interactive outreach, hands-on training, and mentoring focused on the use of social media, online marketplaces, and other relevant digital platforms. The activity was conducted in collaboration with the MSME community using a participatory approach, enabling participants to actively engage in learning and directly apply the materials provided. The results of the activity indicate that participants showed a significant increase in knowledge and awareness regarding the importance of digital branding, designing attractive and effective promotional content, and utilizing various digital tools to expand market access. Additionally, many participants expressed greater confidence in managing digital platforms to promote their products and services independently. This increase in digital literacy is crucial in helping MSMEs remain competitive and adaptive to market changes brought about by technological advances. By equipping MSMEs with relevant digital promotion skills, this initiative contributes to the broader goal of supporting the growth of resilient, sustainable, and innovative small businesses. In the long term, such community-based empowerment efforts are expected to foster economic resilience and inclusiveness in the face of ongoing digital economic transformation.

This article explains the Bakaua ritual at sacred graves, a tradition of the Nagari Sungai Limau community that has deep theological value. This research aims to analyze the meaning of theological values in the Bakaua ritual and how its practice can strengthen people's spiritual relationships. Using a descriptive qualitative approach, this research examines the spiritual, social, and cultural aspects inherent in the Bakaua tradition. The research results indicate that this ritual serves not only as a means of prayer and respect for ancestors but also as a medium for strengthening social relations and preserving local wisdom. Apart from that, the Bakaua ritual is seen as a form of asking for protection, expressing gratitude, and fulfilling vows, which reflects the close relationship between culture and theology in the life of Minangkabau society. The method used in this research is qualitative, encouraging a different approach from previous research, which only discussed Bakaua dramaturgy in the Minangkabau society. However, this paper places more emphasis on aspects of theological values in the Bakaua ritual tradition at sacred graves. This study highlights how theological meaning is embodied through symbolic practices, offerings, and communal prayers that represent submission to divine will. It also reveals how the ritual facilitates intergenerational transmission of spiritual values, maintaining continuity of belief systems in modern contexts. By analyzing community participation and oral narratives, the research uncovers deep spiritual motives rooted in Islamic beliefs intertwined with local cultural expressions. In addition, the findings underscore the community’s resilience in preserving traditional theology-based rituals despite the influence of modernization and shifts in religious interpretations. The Bakaua ritual thus becomes a cultural-theological bridge that binds generations and sustains spiritual identity within the dynamic life of the Minangkabau people.

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.

This study aims to improve student learning outcomes through the implementation of the cooperative learning model of the jigsaw type in science instruction for Grade V students at SDN 76/IX Muaro Jambi. This research is a Classroom Action Research (CAR) using the Kemmis & McTaggart model, which consists of four stages: planning, action, observation, and reflection. The research was conducted in two cycles to measure progressive improvements in student learning outcomes. Data collection techniques included observation, interviews, and documentation. The subjects were all 20 students of Grade V at SDN 76/IX Muaro Jambi. In the pre-cycle stage, before the intervention, only 25% of the students achieved satisfactory learning outcomes, which was categorized as "not yet meeting expectations." After the implementation of the first cycle, student achievement improved to 50%, falling into the category of "approaching fairly successful." However, this result had not yet reached the expected level of success. In the second cycle, the application of the jigsaw-type cooperative learning model was further optimized. The results showed a significant increase, with 80% of students achieving successful outcomes, which was categorized as "approaching highly successful." This improvement demonstrates that the jigsaw model effectively enhances student engagement, individual and group accountability, and conceptual understanding in science learning. Therefore, this study concludes that the cooperative learning model of the jigsaw type has a positive impact on improving student learning outcomes in science. The researcher recommends that teachers, especially in science and religious education (PAI), adopt the jigsaw learning model as a strategic alternative to foster an active, enjoyable, and meaningful learning process. The collaborative nature of the model encourages students to take responsibility for their own learning and for helping their peers, creating a more supportive and productive classroom environment.

Therefore, the company needs to pay attention to both factors to improve employee performance.

In the rapidly evolving digital era, data breaches have emerged as a serious threat, particularly in the e-commerce sector which handles vast amounts of customers’ personal data. The protection of personal data has therefore become a crucial issue, requiring effective regulation to ensure digital privacy. In response to this growing concern, Indonesia enacted the Personal Data Protection Law (UU PDP) in 2022 as a significant step toward strengthening digital privacy and security. This study aims to evaluate the effectiveness of the 2022 PDP Law in addressing customer data breach incidents on e-commerce platforms in Indonesia. Using a qualitative approach and case study method, this research analyzes several high-profile data breach cases involving major e-commerce companies in the country. The findings indicate that, although the PDP Law has established a clear legal framework regarding the obligations of reporting and managing data breaches, its implementation still faces multiple challenges. Some companies have not fully complied with the legal timeframes for notifying users, and there is a general lack of transparency in how data breach incidents are managed. These shortcomings reveal a gap between the regulatory framework and practical enforcement in the field. Furthermore, the study highlights the limited public awareness and the insufficient preparedness of some companies in responding to data security incidents in accordance with the law. As a result, the rights of consumers to be informed and protected are not always upheld effectively. This research recommends stronger supervision by relevant authorities to ensure stricter enforcement of the PDP Law. It also underscores the need for ongoing education and intensive training for e-commerce companies to enhance their capacity to prevent, detect, and respond to data breaches in compliance with the legal standards. By reinforcing regulatory implementation and organizational readiness, Indonesia can better safeguard digital consumer rights in the growing e-commerce landscape.

This study aims to examine the relationship between a company's value (firm value) and three key variables: environmental performance, capital structure, and management ownership. The research focuses on companies listed on the Indonesia Stock Exchange during the period from 2022 to 2024. The objective is to understand how these internal and external factors contribute to shaping a company’s market valuation and overall financial health. Using a panel data regression analysis with a fixed effect model, the study provides empirical evidence based on secondary data drawn from company financial reports and sustainability disclosures. The results indicate that capital structure, measured by the proportion of debt to equity, has a significant negative impact on firm value. In contrast, both environmental performance and the proportion of shares owned by management have a positive and significant effect on firm value. These findings suggest that while excessive debt may erode investor confidence and reduce a firm's valuation, strong environmental commitments and management ownership foster positive perceptions in the eyes of stakeholders, including investors and customers. Theoretically, this research supports stakeholder and agency theories by highlighting how internal governance and ethical responsibility play a role in corporate success. Pragmatically, the results offer important insights for companies, especially in emerging markets like Indonesia, to align sustainability and ownership strategies with financial management to boost firm value. Companies are encouraged to optimize their capital structures, strengthen their environmental reporting practices, and promote management ownership as a way to align interests and enhance long-term performance. Overall, this study contributes to the literature on corporate governance and sustainability by providing current, context-specific evidence relevant to stakeholders in the Indonesian capital market.

Profitability is one of the key indicators in assessing a company's ability to generate profits and plays a crucial role in financial decision-making. According to the pecking order theory, companies with high profitability tend to prefer using internal funds and reduce reliance on debt. This study aims to analyze the effect of profitability on debt policy, as well as to examine the role of dividend policy as a moderating variable in this relationship. The study employed Slovin’s formula for sample selection and analyzed 263 non-financial publicly listed companies on the Indonesia Stock Exchange (IDX) in 2023. The data used in this research were secondary data obtained from annual financial reports published on the official website of the IDX or the respective company websites. Profitability was measured using return on assets (ROA), debt policy was measured by the debt-to-equity ratio (DER), and dividend policy was measured by the dividend payout ratio (DPR). The analytical method used in this study was multiple linear regression analysis with the help of the SPSS software. The results indicate that profitability has a negative effect on debt policy, meaning that the more profitable a company is, the less likely it is to depend on debt financing. Additionally, the findings suggest that dividend policy does not significantly moderate the relationship between profitability and debt policy. This implies that whether a company distributes dividends or not does not meaningfully influence how profitability affects its debt decisions. These results are in line with the pecking order theory and provide insight for corporate financial managers in planning funding structures. It also emphasizes the importance of internally generated funds for companies with strong earnings performance.

This study explores the key determinants of field engineer efficiency in the field service industry by analyzing the impact of self-efficacy, resource management, and time management on operational performance. Employing a quantitative research approach, data were collected using saturated sampling from 102 field engineers and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM) with SmartPLS 4.0. The measurement model showed robust psychometric properties, satisfying the thresholds for convergent validity, discriminant validity, and internal consistency reliability. The structural model results indicate that all three independent variables significantly influence field engineer efficiency. Self-efficacy was found to have the strongest effect (β = 0.421, p < 0.001), followed by resource management (β = 0.347, p < 0.001) and time management (β = 0.289, p < 0.001). The model accounts for 68.7% of the variance in field engineer efficiency, reflecting strong explanatory power and predictive accuracy. Among these variables, self-efficacy emerged as the most dominant factor, suggesting that field engineers' belief in their ability to perform tasks is a critical driver of operational success. High self-efficacy enhances motivation, resilience, and effective problem-solving under pressure, making it essential in dynamic and unpredictable field environments. Resource and time management also play crucial roles in supporting engineers' ability to complete tasks efficiently by ensuring optimal allocation of tools, equipment, and time. The findings provide practical implications for field service organizations aiming to improve workforce performance. Investing in training programs that strengthen self-efficacy, combined with systematic improvements in resource and time management practices, can significantly enhance operational outcomes. By prioritizing these factors, organizations can boost engineer efficiency, reduce operational costs, and improve service delivery, ultimately gaining a stronger competitive advantage in the industry.

This study examines the influence of store atmosphere, service quality, word of mouth (WOM), and price perception on consumer purchasing decisions at Cahya Busana's Canggu branch, a local Balinese MSME specializing in high-quality traditional Balinese clothing for men, women, and children. With an increasing demand for traditional attire, understanding the factors that influence consumer decisions is vital for business growth. The study targeted consumers who had purchased traditional clothing at the Canggu branch, using non-probability sampling to select 110 respondents. The data analysis was conducted through multiple linear regression, assisted by SPSS software, to evaluate the relationship between the independent variables (store atmosphere, service quality, WOM, and price perception) and the dependent variable (consumer purchase decisions). The findings indicate that all four factors—store atmosphere, service quality, WOM, and price perception—positively and significantly impact consumers’ purchasing decisions. Specifically, a pleasant store atmosphere, high-quality service, positive word-of-mouth recommendations, and favorable price perception were found to enhance consumers' likelihood of purchasing traditional Balinese clothing. The results suggest that MSMEs, particularly in the traditional clothing sector, can leverage these factors to boost consumer confidence and drive sales. This study contributes valuable insights for businesses aiming to improve their purchasing processes by focusing on these key variables to increase consumer satisfaction and decision-making. By understanding these influences, Cahya Busana and similar businesses can optimize their strategies to attract and retain customers, ultimately improving their market position.

The F-test results yielded an F-count of 24.591, which is greater than the F-table of 3.191, with a significance value of 0.000, indicating that both variables have a significant influence. The coefficient of determination indicates that price and product quality contribute 51.1% to consumer purchase intention, while the remaining 48.9% is influenced by other factors not examined in this study.

The global demand for energy, particularly fuel oil, continues to increase along with the growth in the number of vehicles and industrial activity. However, limited fossil fuel reserves and the environmental impacts of their use have prompted various studies to find alternative fuels that are more environmentally friendly, efficient, and sustainable. In this context, ethanol and xylene have emerged as two potential fuel additive candidates. Ethanol is known as a biofuel derived from renewable sources and has a high octane rating and oxygen content that can support a more complete combustion process. On the other hand, xylene is an aromatic compound with a high octane rating that can improve combustion stability and reduce the risk of knocking or detonation in engines. This study aims to evaluate the effect of ethanol and xylene additions on the flame characteristics of Pertamax fuel, particularly in terms of flame duration and height. Through a laboratory experimental approach, observations were made on the combustion process of pure Pertamax and several fuel blends with varying ethanol and xylene contents. The results showed that pure Pertamax produced a flame with an average duration of 0.734 seconds and a flame height of 4.5 cm, while one of the best blends, namely the fourth blend containing ethanol and xylene, produced a flame duration of 1.084 seconds and a flame height of 5.7 cm. These findings indicate that the addition of ethanol and xylene can significantly improve combustion performance. These results not only enrich knowledge regarding the combustion characteristics of blended fuels, but also open up opportunities for the development of alternative fuel formulations that are more environmentally friendly, energy efficient, and support reducing dependence on fossil fuels in the future.
