The high volume of fishery waste often poses an environmental burden if not managed appropriately. Conversely, the circular economy concept offers sustainable solutions aligned with Maqasid Shariah principles in environmental preservation (Hifz al-Alam). This study aims to educate and implement the processing of fish waste into high-quality animal feed that meets halal standards (halalan thayyiban). This research employs a qualitative approach using the Asset-Based Community Development (ABCD) method. The stages include socializing the concept of Sharia circular economy, technical training on waste processing, and nutritional content testing of the feed. The findings indicate an 80% increase in community understanding regarding the economic value of waste. Technically, the fish waste processing successfully produced an alternative animal feed with high protein content, free from najis (impurity) through a purification process according to Islamic jurisprudence (fiqh). This education proves that the integration of circular economy and Sharia principles not only reduces environmental impact but also creates sustainable economic added value for local communities.

Amid intense market competition, the profitability of manufacturing companies is not solely determined by sales volume but is highly dependent on the precision of financial management, particularly in managing the working capital cycle and operating cash flow circulation. This study aims to evaluate the relationship between Working Capital Turnover (X1) and Operating Cash Flow (X2) on Profitability (Y) in consumer goods industry companies listed on the Indonesia Stock Exchange during the 2022–2024 period. Using a quantitative approach and multiple linear regression analysis, this study processes 77 observations that have passed purposive sampling and outlier testing. The partial test results reveal contrasting findings: Working Capital Turnover (X1) does not have a significant effect on profitability, while Operating Cash Flow (X2) is proven to be a strong positive determinant. However, simultaneously, both variables have a significant influence on the financial performance of companies (Fhitung 24,008 > Ftabel 3,08), with operating cash flow acting as the dominant driving factor of profit. The implications of these findings emphasize that to maintain profit stability, management should prioritize the availability of cash generated from core operations, while investors should be more attentive to cash flow trends as an indicator of fundamental financial health before making investment decisions.

Nahwu (Arabic grammar) is a fundamental discipline in learning the Arabic language, helping to prevent errors in speech and serving as a primary key to clearly understanding Islamic legal texts. However, in practice, the teaching of Nahwu often faces complex challenges, particularly the lack of active participation among female students and their uneven mastery of the subject. Therefore, this study aims to explore the problems in teaching Nahwu at Al-Madani Islamic Boarding School in Cikalong and to identify the factors causing these issues. This study aims to: (1) reveal the problems faced by second-grade female students of KMI in learning Nahwu at Al-Madani Islamic Boarding School in Cikalong, and (2) identify the contributing factors influencing the emergence of these problems. This research employs a descriptive qualitative approach. The researcher used three data collection techniques: classroom observation, in-depth interviews with the Nahwu teacher, and questionnaires distributed to the students. For data analysis, the researcher applied the Miles and Huberman model, which consists of data reduction, data display, and conclusion drawing. To ensure data validity, data triangulation techniques were used. The results of the study indicate that the problems are divided into two main aspects: (1) learning-related problems, including the gap between memorization of grammatical rules and their application (i‘rab), high levels of academic anxiety, and decreased classroom concentration; and (2) contributing factors, including methodological factors, linguistic-psychological factors, and classroom management factors. The researcher suggests that teachers adopt more interactive teaching methods and media, as well as innovative visual tools to reduce the abstract nature of Nahwu materials and enhance students’ functional understanding. Additionally, activating “Halaqah Nahwiyyah” (grammar study circles) in dormitories is recommended to overcome psychological barriers and improve students’ linguistic confidence.

The rapid development of the Industrial Revolution (IR) 4.0  and the transition towards Society 5.0 demand an increase in digital literacy and a basic understanding of technology systems starting from secondary education. The Community Service (CS) Program conducted by the Department of Electrical Engineering Universitas Presiden aims to introduce the concepts of logic gates and digital systems to students of SMA 1 Cikarang Pusat. This CS integrates theoretical explanations and simulation practice using the online platform Circuitverse. This CS was evaluated using a Likert scale (1–4) questionnaire instrument, namely Expectation (Importance) and Performance, with a total of 40 student respondents. The analysis results show that all indicators received an average performance score above 3.30, with satisfaction indices ranging from 82.50% to 90.62%, which falls into the very high category. The indicator for the use of appropriate technology received the highest score of 90.62%, indicating the relevance of the material to current technological developments.

Urban waste management remains a major challenge in achieving a clean and sustainable environment, including in Bontoduri Sub-district, Makassar City. Waste banks, as a community-based waste management model, have significant potential to reduce waste generation while creating economic value. However, in practice, the role of waste banks has not been fully optimized due to limitations in institutional capacity, community participation, and managerial practices. This community service activity aimed to strengthen the role of waste banks in promoting a clean and economically valuable environment through participatory and community empowerment approaches. The methods employed included preparation, environmental education and socialization, waste bank management training, institutional mentoring, and activity evaluation. The program involved approximately 30 participants consisting of waste bank managers, local government representatives, and community members. The results indicated an increase in community awareness and understanding of waste segregation, improved managerial and administrative capacities of waste bank operators, and enhanced community participation in waste-saving activities. In addition, waste banks contributed to generating added economic value from household waste and reducing the volume of waste disposed of into the environment and landfills. This activity concludes that strengthening the role of waste banks through education, training, and continuous mentoring can serve as an effective strategy to support sustainable urban waste management based on circular economy principles.

The waste problem in Karanglewas Village, Kutasari District, Purbalingga Regency, continues to increase alongside agricultural, trade, and MSME activities, while the management system remains conventional, without sorting, resulting in environmental pollution and limited landfill capacity. This community service program aims to implement the Integrated Independent Waste Sorting and Processing Tool (PLASMA-T) as an innovative solution that processes organic waste into compost and melts plastic waste into paving blocks that are useful and economical. The activities are carried out in stages, including problem identification, socialization, technical training, operational trials, evaluation of results, and the handover of the equipment to the Mitra Sejahtera TPS, with ongoing assistance so that the community can operate the equipment independently. The expected outcomes include a reduction in waste volume at the TPS, increased community awareness and skills in waste management, and the creation of new business opportunities through compost and paving block products. Thus, this program not only addresses environmental issues but also strengthens the village's circular economy and has the potential to serve as a model for other regions.

The pretrial institution serves to regulate the use of coercive measures by authorized organizations during the investigation and prosecution stages. The establishment of this institution is a primary priority aimed at protecting the rights of suspects, particularly in cases involving unlawful arrest or detention, the termination of investigations and prosecutions, and other similar circumstances. However, several weaknesses remain in both the design and implementation of this institution within the judicial system, resulting in insufficient protection of human rights for suspects, despite its regulation under positive law, namely Law Number 8 of 1981. Efforts to safeguard the human rights of suspects during the investigation process constitute the main focus of this study, which examines the legal status of pretrial procedures within Indonesia’s criminal justice system, the challenges in their implementation as a means of protection, the effectiveness of pretrial rulings in this context, and their implications for subsequent investigations.

This community engagement program aims to strengthen the halal value chain of micro, small, and medium enterprises (MSMEs) in Hagu Selatan Village, Banda Sakti District, Lhokseumawe City through knowledge transfer based on the Indonesian halal value chain model. MSMEs play a vital role in regional economic development, yet many still face challenges in understanding halal–thayyiban principles, fulfilling certification requirements, managing production processes, and accessing Islamic financing. Limited adoption of digitalization also reduces their competitiveness in the rapidly growing halal industry. The program applies a participatory approach by involving universities, village authorities, and MSMEs. Key activities include needs assessment, training on halal value chain concepts, technical assistance for halal certification documents, workshops on digital business practices, and business clinics on Islamic financing. A Halal Value Chain Learning Circle is also established to support continuous collaboration and knowledge sharing. The program is expected to enhance MSME capacity, improve product quality, expand market access, and contribute to a sustainable halal ecosystem in Aceh.

This community service program aims to empower the community of Ujung Tanah District, Makassar City in circular economy-based waste management.

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 heart is a vital human organ that plays an important role in the circulatory system. Therefore, an understanding of the heart needs to be given from an early age, starting from basic concepts to more complex aspects. Every human being is created by God with a heart that functions to sustain life, so every individual has the right to gain knowledge about heart health. Adolescents, in particular, need to understand the function and workings of the heart early in order to lower the risk of heart disease in the future. This Community Service (PkM) activity aims to improve the understanding of cardiac physiology in adolescents through the use of digital media. The activity method used is health education about cardiac physiology and how to maintain heart health from an early age. The participants of the activity were 50 students of Madrasah Ibtidaiyah and Junior High School of the Ummul Quro Al-Hamidiyah Foundation. The activity began with the delivery of educational materials, then continued with an evaluation of students' understanding. The results of the activity showed an increase in student knowledge, which indicates that education is effective in forming awareness and early prevention of heart disease.

The rapid development of digital media has created a communication pattern in which information spreads quickly and often without verification. In this situation, hoaxes and disinformation have emerged as a serious threat that affects social trust, religious harmony, and individual behavior in online spaces. This study aims to explore Qur’anic principles that are relevant for building critical awareness, especially through the momentum of Nuzul Qur’an as an illustration of revelation that guides people in understanding messages accurately. The research uses a qualitative descriptive-analytical design with a thematic tafsir approach to examine verses related to verification, prohibition of false speech, and speaking truth. Primary sources consist of the Qur’an and classical as well as modern commentaries, while secondary sources include books and scientific articles on digital literacy and misinformation. The findings show that Qur’anic principles such as tabayyun, avoidance of false accusation, and responsibility in communication are aligned with core elements of digital literacy that require users to identify reliable sources and evaluate messages before sharing. The conclusion suggests that integrating Qur’anic ethical values into digital literacy programs can reduce the circulation of hoaxes and strengthen a culture of truth in digital interaction.

The concept of money in Islamic economics is grounded in the understanding that money is not merely a medium of exchange but a trust that must be managed according to the principles of justice, benefit, and ethical conduct. In this perspective, money cannot be treated as a commodity traded solely for profit without supporting real economic activities, making practices such as usury (riba), excessive uncertainty (gharar), and hoarding incompatible with Islamic values due to their potential to create inequality and economic instability. Islamic economics emphasizes that the circulation of money must be connected to the real sector to generate added value and support sustainable economic growth. Furthermore, the management of money aims to promote fairness and social balance through mechanisms such as zakat, infaq, and charity. Thus, the Islamic view of money provides an ethical foundation and practical framework for developing a financial system that is stable, inclusive, and oriented toward societal well-being.

Organic waste management at Yogyakarta International Airport (YIA) is still not optimal, even though organic waste production averages 1,264 kg per month. This community service activity aims to develop technological innovations through the utilization of eggshell waste and Black Soldier Fly (BSF) maggots into economically valuable pellet feed products. The activity was carried out from October 8 to 15, 2025, involving three workers from the Temporary Processing Site (TPS) of PT Angkasa Pura Indonesia YIA. The implementation methods included an initial survey, education, demonstration of pellet production, and evaluation of participants' skills and product quality. The production process involved drying, grinding the ingredients, mixing the ingredients, molding, and drying the pellets. The results showed that the workers were able to independently carry out the production process and produce pellets with good physical quality. Cost analysis showed that the cost of production was IDR 47,989/kg, with a potential profit margin of 30% and an estimated return on investment within ±7 months. This innovation has proven effective in reducing waste volume, increasing the added value of organic waste, and supporting the principles of zero waste and circular economy in the airport area. This program has the potential to be further developed as a model for sustainable organic waste management.

This study explores the implementation of circular economy principles within Safina Quilt, an MSME in Balikpapan that transforms textile waste—such as fabric scraps and discarded clothing—into value-added products. Safina Quilt applies the concepts of reduction, reuse, and upcycling throughout its production processes using quilting techniques, while simultaneously establishing an inclusive supply chain that engages local tailors, individuals with disabilities, and homemakers. This business model not only delivers economic gains by increasing profit margins and expanding market reach but also generates substantial social benefits by empowering vulnerable community groups. Although challenges remain, including limited access to supporting materials, constraints in production capacity, and insufficient digital marketing efforts, Safina Quilt demonstrates how MSMEs can successfully integrate environmental, economic, and social sustainability. Strengthening supply chain mechanisms, enhancing production capabilities, and improving digital marketing strategies are essential for scaling up and ensuring long-term business sustainability.

This study analyzes the mechanism of money creation in Islamic financial institutions by highlighting its relationship to the principle of prudence and the intermediation function. The research background is based on the growth of Indonesia's sharia capital market which by 2025 will reach a capitalization of IDR 5,060 trillion, but still faces conceptual challenges regarding how money is created according to the principles of maqashid al-shariah. The method used is Systematic Literature Review (SLR) with PRISMA guidance on 38 relevant scientific articles. The results of the study show that money creation in the sharia system only occurs through real asset-based economic activities, in contrast to the conventional system that relies on credit and interest expansion. The intermediation function is carried out through partnerships that prioritize proportional sharing of risk and profit, while the prudential principle ensures that monetary expansion remains under control. In addition, research has found that sharia contracts such as murabahah, mudarabah, and musharakah play a role in encouraging productive money circulation while suppressing speculative activities. This study concludes that the integration between the moral and economic dimensions forms a just, stable, and sustainable Islamic monetary paradigm. These findings make a conceptual contribution to strengthening Islamic financial policy in Indonesia, especially in formulating a monetary regulatory framework that is in line with the principles of distributive justice, transparency, and protection of the stability of the national financial system.
