Cooking oil is a staple food widely used in daily cooking. However, repeated use of cooking oil, resulting in its conversion into used cooking oil, can have negative impacts on both health and the environment. Used cooking oil that has changed color and quality is carcinogenic and has the potential to increase the risk of cardiovascular disease if consumed again. Furthermore, improper disposal of used cooking oil can cause environmental pollution because it is difficult to decompose. This study aims to examine the wise management of household waste, especially used cooking oil, by utilizing it into products with utility value. One form of utilization is processing used cooking oil into environmentally friendly soap for laundry purposes. This activity was carried out as a form of community service through training in making soap from used cooking oil with the addition of essential oils for aromatherapy for residents of Pasar Rawa Village, Gebang District, Langkat Regency. The research method used was qualitative, with observation and direct participation in the training activities. The results showed that participants, particularly housewives, demonstrated high enthusiasm and were actively involved in both the presentation and the soap-making practices. This activity not only raised public awareness of the importance of managing used cooking oil waste but also provided new skills that have the potential to support family economic growth.

This study aims to understand behavioral considerations in decision-making regarding business equipment procurement at UMKM Sido Maju Marsudi. This research applies a qualitative method with a case study approach. Primary data were collected through semi-structured interviews with the business owner. The findings reveal that equipment procurement decisions are not solely influenced by economic rationality but also by behavioral factors such as intuition, experience, and social values. The business owner balances financial benefits with non-financial satisfaction, including customer trust, product quality, and maintaining the traditional identity of “roti kering jadul.” The decision-making process is simple, experience-based, and guided by social recommendations, reflecting bounded rationality. Evaluations are carried out informally by observing production outcomes and customer feedback. This study concludes that behavioral and experiential aspects play a crucial role in shaping adaptive and sustainable business decisions among micro and small enterprises

This study aims to analyze the definition and concept map of Islamic Education (IPI) within the philosophical framework of Prof. Dr. Hasan Langgulung. IPI is strategically positioned as a discipline that bridges theoretical studies and educational practices in responding to contemporary challenges, while also serving as a foundation for character formation. The method used is library research with a qualitative approach, analyzing primary and secondary documents to synthesize a complete IPI concept map. The results of the study show that Langgulung defines IPI comprehensively as a normative field of science, exploring the process of multi-dimensional human growth (physical, soul, mind, spirit), and utilizing integrative sources of knowledge (revelation, reason, experience). This approach is based on three solid philosophical pillars: Ontology (human nature and fitrah), Epistemology (integration of revelation, reason, and experience), and Axiology (utility values to form a perfect human being). Langgulung's thinking elevates the discussion of IPI from the operational level (Tarbiyah, Ta'lim, Ta'dib) to the philosophical level, providing a solid foundation for IPI as a complete discipline.The ultimate goal is to produce a perfect human being capable of fulfilling the balanced roles of 'Abdullah (servant of God) and Khalifatullah fil Ardh (leader on earth), by optimizing the full potential of human nature. This educational model is considered relevant in contemporary discourse to integrate religious and general knowledge and address the moral crisis.

Ngarip Village, Ulubelu District, is one of the coffee-producing areas in Tanggamus Regency. Some residents process the harvested coffee into various micro, small and medium enterprises (MSME) products. This activity produces a byproduct in the form of coffee grounds. Coffee grounds have characteristics that allow them to be processed into products with utility and economic value. This community service activity aims to provide knowledge and skills to the Ngarip Village community on how to process coffee grounds into aromatherapy candles that are attractive, useful, and have the potential to be developed as a creative economy product. The implementation method includes literature studies, field observations, preparation of tools and materials, and socialization and training that includes material presentations, discussions, demonstrations, hands-on practice, and documentation. This training provides knowledge on the concept of 3R-based waste management and techniques for making aromatherapy candles using coffee grounds as an additional ingredient. The implementation results showed that participants were able to understand the process of making aromatherapy candles, from drying coffee grounds, melting wax, mixing ingredients, to the molding stage. Participants also gained knowledge about the benefits of aromatherapy candles for health, the environment, and their economic potential. This training can improve the community's ability to process waste into useful products, while also opening up sustainable home business opportunities. Overall, this activity has a positive impact on increasing public insight, creativity, and awareness regarding organic waste management, as well as encouraging innovations that support local economic independence.

This research explores the symbolic consumption patterns of Generation Z in engaging with local products during the digital hyperreality era, emphasizing the roles of ethical consumption, hyperreality values, and digital identity in shaping purchase intentions. Using a quantitative design through PLS-SEM complemented by qualitative evidence, the study shows that both ethical consumption and hyperreality significantly shape digital identity (β = 0.42; β = 0.53, p < 0.001). Digital identity strongly drives purchase intention (β = 0.65, p < 0.001), while ethical consumption does not directly affect it. Mediation analysis demonstrates that digital identity fully mediates the relationship between ethical consumption and purchase intention, and partially mediates the impact of hyperreality. Qualitative findings highlight that Gen Z’s buying decisions are influenced by symbols and imagery showcased on social media, where ethical aspects only become relevant when they align with digital aesthetics. These results strengthen the postmodernist perspective that consumption in the digital era is primarily about signs, images, and symbols that go beyond mere utility. The study suggests that MSMEs should strategically embed symbolic narratives, ethical dimensions, and visual aesthetics into digital marketing to appeal to Gen Z while promoting sustainability.

The problem of plastic waste in Gandan Hamlet, Pogalan Village, is becoming an increasingly urgent environmental issue that requires sustainable management. Unmanaged waste can pollute the soil, air, and water, and threaten public health. In response to this situation, Tidar University Community Service (KKN) students implemented an innovative community-based waste management program. The main focus of this program is to utilize plastic waste into products with utility and sales value, namely plastic-filled pillows and Eco-Paving Blocks. This activity was carried out through a participatory approach by actively involving the community at every stage, from outreach and education to technical training on the collection, sorting, and processing of plastic waste. The education provided concerns the dangers of plastic waste to the environment and the importance of recycling as an alternative solution. Making pillows from plastic filling was chosen because the process is simple, inexpensive, and can be done by housewives. Meanwhile, Eco-Paving Blocks are the result of utilizing mixed plastic waste as an environmentally friendly and durable building material. This program has succeeded in reducing the volume of plastic waste in the surrounding environment, while raising public awareness of the importance of environmental conservation. Furthermore, this activity opens up new economic opportunities for the community by creating creative products from waste. Evaluation results show that the community-based waste management model is effective in fostering community independence in waste processing, creating a cleaner environment, and encouraging a culture of sustainable living at the village level. The success of this program is expected to serve as an example for replication in other areas with similar challenges. Continued support from the village government and cross-sector collaboration are key to this initiative's continued growth and long-term impact.
