Premarital sexual behavior in adolescents is a public health issue influenced by various individual, social, and environmental factors. Changes in social norms, technological advancements, and limited reproductive health knowledge make adolescents a group vulnerable to risky sexual behavior. This study aims to examine the factors influencing premarital sexual behavior among adolescents based on the Health Belief Model (HBM) approach. The method used is a Systematic Literature Review (SLR), review national and international scientific articles published between 2013 and 2025. Data sources were abtained from Google Scholar and ScienceDirect, with inclusion criteria including articles in Indonesia and English, open access, full text, and relevant to HBM components. The study result indicate that factors such as perceived barriers, self-efficacy, and the quality of information play an important role in shaping adolescent sexual behavior. Low knowledge and limited perception oh the negative impacts of premarital sex increase the risk of engaging in risky sexual behavior. In addition, health promotion interventions based on the Health Belief Model (HBM) have been proven effective in improving knowledge, attitudes, and preventive behaviors regarding premarital sex among adolescents. Therefore, the HBM approach is recommended as a basis for developing comprehensive and sustainable adolescent reproductive health education and promotion programs.

This study examines the contribution of excise revenue from alcoholic beverages to Indonesia’s state revenue during the period 2021–2023. Alcoholic beverages are classified as excisable goods due to their potential negative impacts on public health and social order, making excise duty an important fiscal instrument for both revenue generation and consumption control. The objective of this research is to analyze the trend and magnitude of excise revenue from alcoholic beverages and its role in supporting national income. This study employs a quantitative descriptive method using secondary data obtained from official government publications, including reports from the Ministry of Finance and the Directorate General of Customs and Excise. The data are analyzed by comparing annual excise revenue figures and identifying their contribution to total excise and state revenue over the observed period. The findings indicate that excise revenue from alcoholic beverages showed a fluctuating but generally increasing trend from 2021 to 2023, reflecting post-pandemic economic recovery and adjustments in excise tariff policies. Despite its relatively smaller share compared to tobacco excise, alcoholic beverage excise consistently contributed to state revenue and demonstrated fiscal potential. The study implies that effective excise policy on alcoholic beverages can support state revenue while simultaneously serving as a regulatory tool to control consumption and mitigate social and health risks.

This study identificates the importance of singing national songs as an effort to foster a sense of patriotism among elementary school students in the era of globalization and the 4.0 industrial revolution. The weakening of nationalism among the younger generation today implies that strategies for strengthening nationalism in schools must be changed.

Therefore, optimal management of psychological, pedagogical, and technical factors is essential to improve the effectiveness of online learning for university students.

The relationship between religious doctrine and national identity remains a critical discourse in the Muslim world. The object of this research is Wasathiyatul Islam (Islamic Moderation) in Indonesia, which serves as a theological framework for balancing religious observance with social justice. However, the emergence of rigid transnational ideologies poses a significant challenge to this harmony, creating a potential disconnect between religious doctrine and local culture. To address this issue, this research aims to analyze how the values of Wasathiyatul Islam are transformed and harmonized within the dialectics of Indonesian society. The study employs a descriptive qualitative method with a phenomenological approach. Data were collected through literature reviews and social observations, then analyzed using an interactive model to interpret the "lived experience" of moderation. The results reveal that the harmonization process is manifested through four key indicators: national commitment, tolerance, anti-violence, and accommodation of local culture. A synthesis of these findings demonstrates that moderation in Indonesia is not merely a top-down state policy but an organic, bottom-up cultural practice where local wisdom serves as a vessel for religious values. In conclusion, Wasathiyatul Islam successfully functions as a unifying instrument, creating a "State of Consensus" where Indonesian Muslims practice their faith devoutly while maintaining unwavering loyalty to the nation.

The findings reveal that the most influential HR factors affecting Service Quality include competence, communication skills, work attitude, experience, and employee training. Furthermore, effective human resource management practices demonstrate a positive relationship with improved Service Quality. Nevertheless, the review identifies a lack of comprehensive studies integrating HR management and Service Quality within the specific Context of the Indonesian FnB industry, indicating opportunities for future research.

Honesty (ṣidq) is a fundamental moral value in Islam that serves as the foundation for personal integrity and social ethics. In the current era of globalization and growing materialistic culture, this value faces serious challenges as societal orientation shifts from moral virtue to economic achievement and social image. This study employs a narrative review method, analyzing recent literature on moral education, Islamic ethics, and contemporary social dynamics. The findings reveal that honesty functions not only as a personal virtue but also as a social force that strengthens public trust and national stability. However, the global wave of materialism has weakened the internalization of ṣidq, especially among younger generations. Restoring honesty as the moral identity of the nation requires synergy among character-based education, spiritual reinforcement, and public policies that promote transparency and integrity. The recontextualization of honesty through Islamic spiritual principles and Rokeach’s value theory offers a path toward moral recovery for Indonesian society amid the global challenges of the 21st century.

Production planning and inventory control are critical aspects of operations management, as they directly influence cost efficiency, resource utilization, and the continuity of the production process. Ineffective planning and inventory decisions may lead to excessive costs, production delays, or imbalances between supply and demand. The complexity of these problems, which often involve multi-period horizons and multi-stage decision-making processes, has encouraged the application of quantitative optimization methods, one of which is dynamic programming. This study aims to analyze and synthesize the application of dynamic programming in production planning and inventory control through a Systematic Literature Review (SLR) approach. The SLR process was conducted by systematically identifying, selecting, and analyzing 15 relevant national journal articles published between 2015 and 2024 and obtained from various recognized scientific databases. The reviewed literature indicates that dynamic programming is effective in supporting optimal decision-making by determining appropriate production quantities and inventory levels, minimizing total production and holding costs, and managing fluctuating demand conditions. In addition, this method helps reduce the risks associated with overstock and stockouts by considering sequential decision structures. However, the findings also reveal several limitations of dynamic programming, including high computational complexity, strong dependence on deterministic data assumptions, and limited flexibility in handling high levels of uncertainty. These constraints suggest the need for further methodological development or integration with other approaches to enhance practical applicability.

This study examines the impact of Dutch Military Aggression I (1947) and Dutch Military Aggression II (1948–1949) on the political development of Indonesia during the early years of independence. Employing the historical method (heuristics, source criticism, interpretation, and historiography) and a qualitative diachronic-synchronic approach, the research analyses primary and secondary sources concerning internal political dynamics and the Republic of Indonesia’s international relations in the period 1947–1949. The findings reveal that both Dutch military aggressions paradoxically served as crucial catalysts for the acceleration of national political consolidation and maturation in Indonesia. The First Aggression triggered international condemnation, transformed the Republic’s status from “rebels” to a sovereign state defending its independence, strengthened national solidarity, and gave birth to the integration of armed struggle and diplomacy—the precursor to the Total People’s Defense doctrine. Meanwhile, the Second Aggression, marked by the occupation of Yogyakarta and the arrest of republican leaders, led to the establishment of the Emergency Government of the Republic of Indonesia (PDRI), closer civil-military coordination, unification of political parties and societal organizations, and heightened global pressure that ultimately resulted in the recognition of sovereignty in 1949. Overall, Dutch military pressure expedited the transformation of political structures, bolstered the legitimacy of the Republican government, and secured both de facto and de jure recognition of Indonesian independence.

Intellectual Property Rights (IPR) are the result of human thought that have economic and social value and play a significant role in encouraging creativity, technological innovation, and sustainable national development. IPR protection not only aims to provide legal certainty for creators and rights holders, but also serves as a strategic instrument in strengthening the creative economy. However, low public awareness of the importance of IPR protection and the gap between legal norms and practices in the field result in frequent violations of intellectual works. This study uses a normative-juridical approach combined with a participatory-educational approach, in accordance with the characteristics of community service activities in the legal field. This approach aims to integrate normative legal analysis with legal education activities for the community, thereby producing both conceptual understanding and practical benefits. The results of the activities show a significant increase in public understanding of the relationship between constitutional principles and IPR protection in Indonesia. Through educational activities and legal dialogues, it was revealed that the integration between constitutional principles and the IPR legal system has not been optimal, not only due to limited regulations, but also weak public legal awareness and the application of substantive justice as mandated by the 1945 Constitution. These findings emphasize the importance of integrating constitutional values ​​in the IPR protection system.

The policy of involving expatriates in the board of directors of State-Owned Enterprises (SOEs) has become a debated issue, particularly regarding its implications for corporate governance and national workforce interests. The main problem discussed in this article is how the policy of expatriate involvement in the board of directors of PT Garuda Indonesia is viewed from the perspective of Good Corporate Governance (GCG). This study aims to analyze the suitability of the policy with GCG principles and its implications for corporate governance and company performance. The research method used is a literature review by examining laws and regulations, academic journals, policy reports, and other relevant secondary sources. The analysis is conducted based on five main GCG principles, namely transparency, accountability, responsibility, independence, and fairness. The results show that the involvement of expatriates in the board of directors of PT Garuda Indonesia has the potential to strengthen corporate governance through the adoption of global managerial standards, improvement of institutional credibility, and acceleration of organizational transformation and efficiency. However, this policy also faces challenges, especially related to transparency in the selection process and the assurance of knowledge transfer to local human resources. It can be concluded that the expatriate involvement policy will provide optimal benefits if it is implemented consistently with GCG principles and accompanied by a strong commitment to strengthening local managerial capacity.

Global social inequality remains one of the fundamental challenges in the contemporary world economic system. The dominance of capitalist economic structures, which emphasize growth and capital accumulation, has proven effective in stimulating economic progress; however, it has simultaneously widened the gap between wealthy and disadvantaged groups at both national and global levels. Meanwhile, socialist economic systems that prioritize income equalization continue to face limitations related to efficiency and innovation. This article aims to examine the role of Islamic economics as an alternative economic framework capable of addressing the challenge of global social inequality. The study employs a qualitative descriptive approach through a literature review of classical and contemporary sources related to global economic systems. The findings indicate that Islamic economics offers a more balanced paradigm by integrating principles of distributive justice, ethical values, and social responsibility within economic activities. Instruments such as zakat, infaq, sadaqah, waqf, along with the prohibition of riba and other exploitative economic practices, serve as essential mechanisms for reducing social inequality. Therefore, Islamic economics holds significant potential as both a normative and practical solution for promoting sustainable global economic justice.

Pulmonary tuberculosis (TB) remains a major public health problem in Indonesia. Despite the implementation of national TB control programs through the Directly Observed Treatment Shortcourse (DOTS) strategy, treatment success continues to face significant challenges, particularly related to patient adherence to anti-tuberculosis drug (ATD) therapy. Non-adherence to TB treatment can lead to treatment failure, disease relapse, and the development of drug-resistant tuberculosis, thereby increasing the overall burden of the disease.Treatment adherence in TB patients is influenced not only by medical factors but also by social and behavioral determinants. Family support plays a crucial role in encouraging patients to comply with treatment regimens by providing motivation, reminding medication schedules, and offering emotional support throughout the long duration of therapy. Patients who receive adequate family support tend to demonstrate higher levels of treatment adherence compared to those with limited support.In addition, the use of herbal medicine as a preventive and supportive health measure is common among the Indonesian population. Herbal medicine is often utilized to enhance immune function, reduce medication side effects, and improve patient comfort during TB treatment. However, the use of herbal remedies without proper medical guidance may lead to misconceptions regarding standard TB therapy.Therefore, it is important to examine the relationship between family support and the use of herbal medicine as preventive measures with treatment adherence among pulmonary TB patients in primary healthcare settings. Such evidence is expected to support a comprehensive family medicine approach and strengthen TB control programs in primary care services.

The Indonesia–European Union Comprehensive Economic Partnership Agreement (IEU-CEPA) signed in September 2025 opens significant economic opportunities through the elimination of 98% of tariffs and broader access to the European Union market. However, the implementation of this agreement poses serious challenges for Micro, Small, and Medium Enterprises (MSMEs), which contribute 60% of GDP and absorb 97% of the national workforce. This research analyzes the readiness of Indonesian national law in supporting MSME participation in facing IEU-CEPA implementation using normative juridical methods with statutory and conceptual approaches. The research findings show that although IEU-CEPA offers 0% tariffs for 95% of Indonesian products, MSMEs face barriers in meeting European Union technical standards such as Technical Barriers to Trade (TBT), Sanitary and Phytosanitary Measures (SPS), and European Union Deforestation Regulation (EUDR). National regulations such as Law Number 20 of 2008 and Government Regulation Number 7 of 2021 have not yet regulated mechanisms for assisting MSMEs in meeting international standards, traceability systems, and special legal protection. The research recommends comprehensive legal harmonization and reform strategies including regulatory revision, establishment of an IEU-CEPA Task Force for MSMEs, adequate budget allocation, capacity building programs, and strengthening legal protection mechanisms to ensure MSMEs optimally utilize IEU-CEPA opportunities.

Brebes Regency is one of the main national centers of shallot production in Indonesia, where agricultural land dynamics play a crucial role in sustaining production performance. Rapid infrastructure development and land-use change have raised concerns regarding the sustainability of shallot cultivation areas. This study aims to analyze spatial–temporal changes in shallot cultivated area and production in Brebes Regency during 2023–2024 and to examine the relationship between land area changes and production levels at the sub-district scale. A descriptive quantitative approach based on spatial analysis was employed using Geographic Information Systems (GIS). Spatial data consisted of administrative boundary maps, while non-spatial data included shallot cultivated area and production data obtained from the Brebes Regency Office of Agriculture and Food Security. Data integration and analysis were conducted using QGIS through attribute joining and inter-annual comparison. The results indicate that total shallot cultivated area increased from 26,331 ha in 2023 to 28,628 ha in 2024, accompanied by a significant rise in production from 289,942.05 tons to 409,106.90 tons. Spatial analysis reveals that major production centers remain concentrated in the central and northern sub-districts, particularly Wanasari, Larangan, Bulakamba, and Tanjung. Although a positive relationship between land expansion and production increase is evident, variations among sub-districts suggest that productivity and local conditions also play important roles. The findings highlight the effectiveness of GIS-based analysis in supporting spatially informed agricultural land management and policy formulation.

The phenomenon of unregistered marriages in Indonesia is a complex issue that continues to spark debate between religious legitimacy and legal validity under national law. From an Islamic legal perspective, marriage is considered valid if it meets the essential pillars and requirements, such as the presence of a guardian, two witnesses, a dowry, and the consent (ijab qabul) both the bride and groom. However, according Indonesian national law, specifically Law Number 1 of 1974 concerning Marriage and the Compilation of Islamic Law (KHI), every marriage must be officially registered to receive legal recognition and protection. This discrepancy between the two legal systems raises serious problems, particularly regarding the legal status of wives and children, inheritance rights, and legal protection for women in both the private and public spheres. This study aims analyze the issue of unregistered marriages in Indonesia from the perspectives of Islamic law and national law, and to identify the social and legal impacts unregistered marriages. The approach used is normative-juridical, by analyzing legislation, classical and contemporary Islamic legal literature, and empirical case studies in the community. Research findings indicate that although unregistered marriages are considered valid religiously, they lack legal force the eyes of the state, leading to unequal rights for women and children. This situation results in difficulties obtaining birth certificates, inheritance rights, and legal protection cases divorce or domestic violence. This research emphasizes the need for synchronization between Islamic and national legal systems through strengthening regulations and public education regarding the importance of marriage registration.
