Increased production in the lubricant industry has become a significant issue because it generates production waste in the form of packaging, plastic, and paper waste as a direct consequence of manufacturing activities. Proper and systematic waste management is essential to reduce environmental impacts, comply with regulations, and support responsible and sustainable business practices. Lubricant production waste can damage the ecosystem and surrounding environment if not managed properly, so continuous innovation is needed to minimize environmental risks and reduce potential economic losses for the company. This study aims to analyze and implement effective waste management strategies using a combination of qualitative and quantitative approaches, including in-depth interviews with relevant stakeholders and analysis of secondary data obtained from company records. The waste management process begins with several waste reduction programs applied during the production stage to limit waste generation. Furthermore, the waste storage facility (TPS) available on the company’s premises, covering an area of 59 m², is capable of accommodating approximately 60% of the total waste that must be processed internally before further treatment or disposal.

The danger of cadmium contamination in water sources remains a crucial environmental issue due to its persistent nature and high toxicity level, which poses serious risks to human health and ecosystems. Cadmium is a non-biodegradable heavy metal that can accumulate in living organisms over time. The presence of these toxic Cd²⁺ ions is known to trigger damage to vital organs such as the liver and kidneys; therefore, reducing their concentration in aquatic environments is of paramount importance for environmental protection and public health safety. Among various treatment methods, adsorption is considered one of the most effective and economical techniques for removing heavy metal ions from contaminated water. In this study, the capability of mesoporous silica MCM-48-NH₂ as an adsorbent for Cd²⁺ ions was systematically evaluated. The adsorption performance was examined by investigating several important parameters, including contact time, solution acidity level (pH), and initial Cd²⁺ concentration. Furthermore, the adsorption mechanism and interaction between Cd²⁺ ions and the adsorbent surface were analyzed using Langmuir and Freundlich isotherm models. The results demonstrate that the adsorption process of Cd²⁺ ions onto MCM-48-NH₂ tends to follow the Langmuir isotherm model, indicating monolayer adsorption behavior, with a maximum adsorption capacity of 0.66 mmol g⁻¹.

This research analyzes the legal status of zakat within the state financial system and explores its potential integration as a sharia-based fiscal instrument in Indonesia through a comparative study with Malaysia. In Islamic law, zakat functions both as a religious obligation and as a mechanism for wealth redistribution aimed at achieving social justice. However, under Indonesia’s positive law framework, zakat is still treated as a socio-religious institution outside the formal state fiscal system, as stipulated in Law Number 23 of 2011 on Zakat Management. In contrast, Malaysia has successfully integrated zakat into its Islamic fiscal policy through the authority of the State Islamic Religious Council (MAIN), which holds legal legitimacy as a regional public body. This study adopts a normative and comparative legal approach by examining statutory regulations, Islamic legal doctrines, and zakat institutional practices in both countries. The findings indicate that the integration of zakat into Indonesia’s fiscal system is constitutionally permissible and does not conflict with Article 23A and Article 34 paragraph (1) of the 1945 Constitution, as it aligns with welfare state principles and the state’s responsibility toward poverty alleviation. The legal implications of such integration include the establishment of lex specialis regulating zakat as a sharia fiscal instrument, harmonization with state finance laws, and the strengthening of institutional legitimacy and accountability in zakat management. Therefore, zakat holds significant potential to become a core pillar of Islamic economic law that supports economic equity and enhances national fiscal resilience.

Mosque-based community economic empowerment activities have significant potential to improve community welfare, particularly for small businesses in the mosque's immediate vicinity. However, implementation is still largely conventional and lacks a data-driven approach, resulting in suboptimal beneficiary identification and activity evaluation. This community service initiative aims to promote a data-driven approach to mosque-based community economic empowerment through sharia bazaar activities. Implementation methods include initial observation, outreach and education for mosque managers and business owners, technical assistance for sharia entrepreneurship, and activity evaluation. The results demonstrate an increased public understanding of the importance of data use in determining beneficiaries, managing bazaar activities, and developing businesses based on sharia economic principles. The outcomes of this initiative include improved data management literacy, a simple data collection format for sharia bazaar activities, and recommendations for developing a mosque-based data collection system. It is hoped that this initiative will be the first step in building a sustainable, transparent, and data-driven community economic empowerment model within the mosque environment.

This article examines the effectiveness of fermented kombucha drinks in enhancing the immunity of menopausal women through an evidence-based nutrition approach. Additionally, the study highlights how community-based kombucha production and consumption programs can be part of non-military health diplomacy, supporting community resilience, especially for vulnerable groups like menopausal women who experience immune function decline due to hormonal changes. Using the Systematic Literature Review (SLR) method, the study analyzes 30 relevant articles published between 2018–2025 from reputable sources such as Scopus, PubMed, and others. The findings show that (1) kombucha improves immunity through cytokine modulation and increased antioxidant activity, (2) kombucha normalizes gut microbiota, contributing to the immune health of menopausal women, (3) fermentation variations and microbial composition affect kombucha's effectiveness, and (4) community-based kombucha production programs have potential in enhancing health literacy and local economic empowerment. This study provides a basis for local governments, health centers, and communities to integrate kombucha as a preventive health intervention, while also strengthening community resilience through nutrition education and functional food entrepreneurship. The article also offers a new conceptual model, “Kombucha Intervention – Immunity – Health Diplomacy,” that connects biological evidence, community health, and non-military resilience integratively.

This study analyzes the contribution of the nighttime economy to the development of micro, small, and medium enterprises (MSMEs) in Pekanbaru City, particularly the culinary sector, which dominates nighttime economic activity. This research is motivated by the increasing public consumption at night, which shapes urban economic dynamics and requires effective public governance. The research method uses a qualitative approach through literature review and in-depth interviews with nighttime MSMEs to describe business conditions and governance challenges. The analysis is based on Adam Smith's Theory of Economic Growth, emphasizing capital accumulation, population growth, and technological advancement. The results show that nighttime economic activity generates high levels of consumption, which increases MSME income and enables capital accumulation for business development and product quality improvement. Urban population growth and the use of digital technology, including social media, delivery services, and digital payment systems, contribute to expanding market reach and improving business efficiency. However, MSME development in the nighttime economy remains constrained by limited access to capital, inadequate public infrastructure, and regulatory uncertainty. This study emphasizes the need for integrated local government policies.

The phenomenon of the dual role of wives is a complex social reality amidst the patriarchal culture that is still deeply rooted in Indonesian society. In this social system, women often bear the double burden of domestic responsibilities as well as public roles, which often gives rise to gender inequality, role conflict, and psychological stress. This article aims to analyze the dual role of wives in a patriarchal culture using a gender perspective and maqasid sharia as an analytical framework. The research method used is a literature study with a qualitative-descriptive approach to various relevant literature. The results of the study indicate that patriarchal culture tends to limit access and recognition of women's roles, thus contradicting the principle of gender justice. Meanwhile, maqasid sharia emphasizes the values ​​of balance, justice, and benefit in husband-wife relations. The principles of hifz ad-din, hifz an-nafs, hifz al-aql, hifz an-nasl, and hifz al-mal provide theological legitimacy for women's social and economic roles as long as they are carried out within the framework of justice, shared responsibility, and family harmony.  

The objective is to analyze the competitiveness of modern retail through the integration of SWOT analysis as a basis for formulating more targeted strategies using qualitative descriptive methods. This paper identifies the strengths, weaknesses, opportunities, and threats that drive the performance of modern retail based on literature and empirical findings from various previous studies.

Meanwhile, weaknesses arise from suboptimal digitization, minimal online promotion, limited service innovation, and outdated inventory management. Meanwhile, opportunities arise from changes in digital-based shopping behavior, while threats emerge from the dominance of large retailers, e-commerce competition, and economic fluctuations. Based on the SWOT integration, a strategy is formulated that includes strengthening digitalization, optimizing online marketing, improving service quality, and modernizing operational systems to support long-term competitiveness.

This study examines the optimization of military defense in North Sulawesi as a supporting pillar for Indonesia’s new import gateway. Positioned strategically on the Pacific rim, North Sulawesi is expected to become a hub for imported goods to support national economic equalization. However, this import route shift also brings security challenges, including military and non-military threats such as smuggling, maritime crimes, and potential infiltration by terrorist groups. This research employs a qualitative descriptive method based on literature study, focusing on the analysis of naval and air defense strategies, modernization of main weapon systems (alutsista), and the enhancement of human resources within the Indonesian National Armed Forces (TNI). The results indicate that strengthening defense infrastructure, including the addition of warships, patrol vessels, and modern fighter aircraft, is urgently needed to maintain regional stability. Furthermore, the application of the smart defense concept, integrating advanced technology with local community empowerment, can sustainably enhance maritime resilience. Investment in the defense sector has been shown to create a conducive climate for international trade, boost investor confidence, and strengthen Indonesia’s economic connectivity with the Asia-Pacific region. This study recommends synergy between the Ministry of Defense, TNI, and the national defense industry to accelerate the modernization and maintenance of alutsista, while ensuring the security of trade routes in North Sulawesi. With these measures, North Sulawesi can function optimally as a strategic import gateway that supports national economic growth and reinforces state defense.

This study investigates the strategic strengthening of the rambak cracker industry as an instrument for local economic development in Penanggulan Village, Pegandon District, Kendal Regency. Rural agro-processing enterprises have increasingly been recognized as territorially embedded production units capable of generating value-added outputs and absorbing surplus labor within localized economic systems. Field-based empirical observations reveal that rambak production in the village operates through household-managed processing systems characterized by traditional production techniques, informal managerial practices, and limited digital marketing adoption despite contributing significantly to community income generation. Data obtained from expert respondents were analyzed using the Analytical Hierarchy Process to identify strategic priority determinants influencing industrial competitiveness and sustainability. The results indicate that product innovation and quality improvement constitute the primary strategic priority, followed by digital marketing development and institutional partnership strengthening, while production capacity expansion remains comparatively less influential in enhancing market competitiveness. These findings suggest that adaptive innovation and digitally enabled commercialization pathways function as critical mechanisms for improving value-chain integration and expanding market accessibility among rural food-processing industries. Strengthening innovation ecosystems within the rambak sector may therefore contribute to employment creation, income diversification, and sustainable community-based economic transformation in rural production clusters.

This study aims to analyze the role and effectiveness of Islamic monetary policy in Indonesia in facing digital transformation, particularly through the instruments of Sertifikat Bank Indonesia Syariah (SBIS) and Sukuk Bank Indonesia (SukBI). The digital transformation of the national financial system demands an adaptive monetary policy that remains grounded in the principles of maqashid shariah. In the context of Islamic economics, monetary policy not only functions to regulate the money supply and maintain price stability but also ensures the realization of justice and economic welfare. This research employs a descriptive qualitative approach, using literature-based data collection from official publications of Bank Indonesia, the Financial Services Authority (OJK), and relevant academic references on Islamic monetary policy. The analysis adopts an inductive approach by examining the roles of SBIS and Sukuk BI in supporting the stability of the Islamic financial system and their alignment with maqashid shariah values such as al-‘adl (justice), al-wudhuh (transparency), and ar-rawaj (circulation of wealth). The findings indicate that digitalization has positively impacted the efficiency and transparency of Islamic monetary instruments, where SBIS plays a role in regulating the liquidity of Islamic banks in a non-usurious manner, while Sukuk BI serves as an essential instrument in maintaining national economic stability. Nevertheless, challenges remain, including the limited digital infrastructure for Islamic finance and the need to strengthen regulations to ensure that digital monetary systems remain consistent with sharia principles.

This community service program aims to empower the community of Ujung Tanah District, Makassar City in circular economy-based waste management. Ujung Tanah District as a coastal area with high population density faces complex waste problems, especially waste that ends up in the sea and disrupts the coastal ecosystem. The activities were conducted in four urban villages, namely Ujung Tanah, Tabaringan, Pattingalloang, and Pattingalloang Baru, involving 120 households as direct participants. The implementation methods included socialization and education, waste sorting and processing training, establishment of Waste Banks, mentoring for recycled product creation, and marketing system development. The results showed a significant improvement in community knowledge about waste management, with average scores increasing from 45.2 to 82.6. Four active Waste Bank units were established with a total of 320 household customers. The managed waste volume reached 2.4 tons per month with an economic value of IDR 8,500,000 per month. Recycled products include ecobrick crafts, bags from plastic packaging, and compost fertilizer. This program successfully changed the community paradigm from dumping waste into the sea to managing waste as a source of income.

The rapid development of urban areas has created significant challenges in mobility, particularly the increasing use of private motor vehicles, which contributes to traffic congestion, air pollution, greenhouse gas emissions, and a decline in the quality of urban life. Sustainable transportation emerges as a solution by emphasizing the balance between environmental, social, and economic aspects through the use of eco-friendly modes such as public transport, walking, and cycling. However, the adoption rate of these modes remains relatively low due to perceptions of convenience, car-oriented culture, and limited environmental awareness. This study aims to analyze the implementation of sustainable transportation education as a strategy to raise urban communities’ awareness of eco-friendly mobility. The research employs a qualitative approach with descriptive analysis based on literature studies. Findings indicate that the use of digital media, social campaigns, and community participation plays a crucial role in shaping positive attitudes, new social norms, and pro-environmental behavior. Effective education not only delivers information but also builds values, norms, and new habits that support sustainable mobility. Furthermore, multi-stakeholder collaboration among government, communities, and the private sector strengthens the effectiveness of educational programs. Evaluation results show that continuous education enhances transportation literacy, ecological awareness, and urban quality of life. Thus, the implementation of sustainable transportation education serves as a strategic foundation for transforming urban mobility toward a healthier, inclusive, and equitable transportation system.

This research extends the previous work of Tsaqila, Winiarti, and Widaningrum (2024), who applied the Complex Proportional Assessment (COPRAS) method within a decision support system for supermarket branch location selection. Unlike the prior study, which focused on Ponorogo through a web-based framework, this study expands the implementation of COPRAS to the Medan Area, Medan Kota, Medan Polonia, dan Medan Maimun districts, adapting it to local urban, social, and economic characteristics. The main objective is to identify the most strategic site for a new supermarket by analyzing multiple criteria, including land cost, population density, accessibility, safety, cleanliness, and disaster risk. Data were collected from both field surveys and official government publications. The findings reveal that the COPRAS method provides reliable and objective assessments among the evaluated alternatives, with Medan Area emerging as the most suitable location for supermarket development. Overall, this study broadens the practical scope of the COPRAS method in a different regional context and reinforces its reliability and adaptability as a multi-criteria decision-making tool in the modern retail industry.

Food tourism is increasingly recognized as a strategic component in enhancing the competitiveness of tourism destinations, particularly thru the development of local cuisine based on local wisdom. However, most research still views digital platforms as partial promotional tools and has not yet studied how to use them systematically to build a sustainable culinary tourism ecosystem. The purpose of this study is to examine how digital platforms contribute to the development of local cuisine and how they contribute to the strengthening of sustainable culinary tourism. This is the culinary tourism destination that is the subject of this study, which was conducted using the case study method. Data was collected thru in-depth interviews with culinary MSME producers, destination managers, and tourists, as well as online observations via social media, travel review platforms, and culinary markets.

The latest finding in this research is the development of a multi-platform digital integration model that serves not only as a marketing tool but also as a collaborative ecosystem that helps local economic growth, preserves culinary cultural heritage, and enhances the competitiveness of tourist destinations. The results of this research contribute conceptually and practically to building sustainable digital-based culinary tourism strategies.

The increasing number of children facing the law in Indonesia indicates that the repressive legal approach has not been fully effective in addressing juvenile crime. Children, as subjects of law, have social and psychological characteristics that differ from adults, so law enforcement against them must consider humanitarian and educational aspects. This research aims to analyze the factors causing children to commit criminal acts and formulate a model for addressing them based on developing a legal culture rooted in Pancasila values. This research employs a normative juridical method with conceptual and legislative approaches, and analyzes data qualitatively thru literature review and positive legal norms. The research findings indicate that the causes of children committing criminal acts are multidimensional, encompassing family factors, social environment, education, economics, and psychological factors. Therefore, mitigation efforts cannot be done partially, but must be thru a preventive, educational, and restorative approach. This research offers a model for overcoming challenges thru the development of a legal culture based on five main pillars: family, education, society, the state, and the legal system. This model emphasizes the importance of synergy between law enforcement and moral development in accordance with the values of Divinity, Humanity, Unity, Deliberation, and Social Justice. Thus, the development of Pancasila legal culture is expected to realize a child criminal justice system that is humanistic, substantively just, and oriented toward social rehabilitation in accordance with the legal ideals of a Pancasila state of law.
