The digitalization of the creative economy has opened up significant opportunities for the community to create innovative products that have high sales value and are environmentally friendly. One interesting innovation is the use of used cooking oil as a raw material for making aromatherapy candles. Used cooking oil, which is usually discarded and pollutes the environment, can be reprocessed into products with economic value, thus supporting the principles of a circular economy. This study aims to examine the potential of processing used cooking oil into aromatherapy candles, analyze digital-based marketing strategies to increase product competitiveness in the market, and examine the meaning of transforming waste into innovative products from the perspective of Immanuel Kant's philosophy of reality. The research methods used were literature studies and field observations of used cooking oil processing practices by the community. The results show that used cooking oil-based aromatherapy candles have good business prospects, especially when combined with digital promotion through social media and marketplaces. Digitalization helps expand marketing reach, create brand identity, and attract consumers who care about environmental sustainability. From the perspective of Immanuel Kant's philosophy of reality, the transformation of used cooking oil into aromatherapy candles can be understood as a phenomenon, namely a reality that is visible in the practice of the digital creative economy. Meanwhile, the values ​​of sustainability, ethical awareness, and social meaning contained therein reflect noumena, namely the deepest reality that is not directly visible but provides direction and meaning for human actions.

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 analyze the effect of the price of packaged cooking oil and bulk cooking oil on the elasticity of demand as one of the staple foods in Ciawitali Market, Garut Regency. The approach used is a quantitative descriptive method with a focus on associative analysis. Data were collected through observation and interviews in the period of September and October 2025. Then processed using simple linear regression analysis and demand elasticity analysis. The results show that the demand for both types of cooking oil is strongly influenced by price. For packaged cooking oil, it shows that 81.6% of the variation is influenced by price while the rest is influenced by other factors. For bulk cooking oil, it shows that 94.1% is influenced by price with an elasticity value of -6.346, which also shows elastic properties but lower than packaged oil which has an elasticity of -22.15. These results indicate that the increase in the price of packaged and bulk oil significantly reduces the amount of demand, with the greatest effect occurring on packaged oil because consumers tend to switch to more economical bulk oil.

This study explores the practice of participatory communication and creative production implemented by the Anggrek Waste Bank along the Ciliwung River as an educational strategy for flood disaster mitigation. The research aims to understand how community-based waste management initiatives can serve as platforms for environmental learning and social empowerment. Using a qualitative approach with a case study method, this study investigates social dynamics, interaction patterns, and meanings constructed by residents through collaborative waste management and creative production activities. Data were collected through observation, in-depth interviews, and documentation. The findings reveal that participatory communication is manifested not only in formal education, counseling, or campaigns, but also in everyday interactions, creative workshops, and collective community work. Creative products such as recycled crafts, soap made from used cooking oil, and eco enzymes function as symbolic communication media that persuasively convey ecological messages while providing tangible economic benefits. These practices foster a sense of ecological responsibility, strengthen social solidarity, and enhance community resilience to flooding. This study concludes that participatory communication integrated with creative production serves as an effective model for promoting sustainable behavior and community-based flood mitigation in urban environments.

This community service program was designed to empower the women’s group PKK RT 01 RW 08 in Tembalang, Semarang, through education and innovation in processing used cooking oil into eco-friendly floor cleaner. Household cooking oil waste, commonly known as “jelantah,” is often discarded and contributes to environmental pollution, while in fact it can be reused as a valuable resource.

During the activities, participants were introduced to the principles of green chemistry, practiced step-by-step floor cleaner production, and learned packaging and digital marketing techniques. As a result, the group successfully produced 65 bottles of “Lely Eco Floor” cleaner (260% of the initial target), distributed them for household use, and established an environmental movement group named “Lely Bersih Lestari.” Pre- and post-test scores indicated significant improvement in participants’ knowledge and skills. The program brought multiple impacts: reducing oil waste pollution, enhancing social cohesion, and opening opportunities for micro-scale entrepreneurship. Overall, this activity demonstrates how simple technology and community engagement can support sustainable development and women’s empowerment at the grassroots level.
