Abstract

Styrofoam is widely used as packaging for food, drinks and electronic goods. Usually stirofoam is only used once and thrown away. Styrofoam causes environmental problems, so efforts are needed to degrade it. Using larvae Tenebrio molitor is expected to be an innovative and environmentally friendly solution. The larval stage is used because larvae require large amounts of food for their growth. The larvae's food consists of organic waste such as fruit, vegetables, leaves, rice and others. In fact, stirofoam is considered organic waste because it is made from petroleum which contains hydrocarbons. T. molitor were chosen because they are not consumed by humans. This research aims to analyze the ability of T. molitor to be biodegradation agents for stirofoam. The research stages include cultivating T. molitor for 30 days and analysis which includes viability analysis and larval content using FTIR. The research method used is an experimental method with quantitative data collection. The results of the study showed that even though there was chewing activity, there was no stirofoam content in the bodies of T. molitor.

Abstract

Peron Village, Kendal Regency, is one of the coffee production centers in Central Java that generates large amounts of coffee husk waste. This waste has the potential to cause environmental problems if it is not properly managed. Coffee husks can be processed into cascara, a value-added product that supports the concept of a circular economy. This article aims to describe efforts to optimize coffee plantation waste into certified cascara products through assistance in fulfilling food safety standards and business legal requirements. This activity is part of the Student Organization Capacity Building Program (PPK Ormawa) implemented in Peron Village, involving the Sekar Group as a partner. The implementation method employed a participatory approach through several stages, including problem identification using Participatory Rural Appraisal (PRA), assistance in the cascara production process, socialization on the importance of SP-PIRT certification, technical and administrative assistance, sanitation counseling, as well as monitoring and evaluation. The indicators of success for this activity included active member participation, administrative readiness, successful processing of coffee husk waste, a more hygienic and standardized production process, increased understanding of food safety, and the issuance of an SP-PIRT certificate (one document). The results show an increase in the partners’ capacity for the hygienic and sustainable processing of coffee husk waste, improved understanding of food regulations, and enhanced business administrative readiness. This assistance successfully facilitated the issuance of an SP-PIRT certificate for the cascara product “Peronara Tea,” which has contributed to increased consumer confidence and expanded product marketing opportunities. Thus, the optimization of coffee husk waste based on a circular economy approach, supported by business legality, has proven to strengthen the competitiveness and sustainability of community-based MSMEs.
