Abstract

Socialization activities for processing tofu waste into alternative energy were carried out at the Serasi Tofu Industry, Bandungan. This activity aims to provide understanding and skills to tofu entrepreneurs and the surrounding community regarding managing tofu waste into a more environmentally friendly energy source. This outreach includes an introduction to waste processing techniques, such as anaerobic fermentation to produce biogas, and solid residue as organic fertilizer. Through this activity, participants can apply this waste processing technology, thereby reducing the negative impact of tofu waste on the environment and at the same time providing a sustainable energy alternative. The results of the socialization show an increase in awareness and readiness of tofu entrepreneurs to adopt the waste processing methods that have been presented.

Abstract

Cangkang rajungan merupakan limbah yang dihasilkan dari industri pengalengan rajungan dan menjadi limbah yang belum tertangani dengan maksimal. Oleh karena itu untuk meningkatkan nilai ekonomisnya, cangkang rajungan dijadikan sebagai bahan baku gelatin. Gelatin adalah derivat protein dari serat kolagen dari serat kolagen pada kulit, tulang, dan tulang rawan. Fungsi gelatin adalah sebagai pengemulsi (emulsifier) dan penstabil (stabilizer) dalam sistem emulsi. Tujuan penelitian ini adalah mengetahui variabel yang paling berpengaruh dari suhu, waktu, dan perbandingan ossein dan aquadest, mengetahui kondisi optimum dari variabel yang berpengaruh, mengetahui kondisi optimum dari variabel yang berpengaruh, mengetahui karakteristik gelatin yang diperoleh sesuai dengan standar mutu gelatin (SNI), dan mengetahui kemampuan gelatin yang dihasilkan sebagai emulsifier. Penelitian ini menggunakan metode experimental design two level untuk menguji variabelvariabel yang berpengaruh berupa suhuhidrolisis (A) 60°C dan 80°C, waktu hidrolisis (B) 4 jam dan 6 jam, dan perbandingan ossein : aquadest (C) yaitu 1 : 2 dan 1 : 4. Hasil penelitian ini menunjukkan bahwa suhu hidrolisis merupakan variabel yang paling berpengaruh,dengan persentase yield gelatin optimum sebesar 3,05% pada suhu 60°C. Gelatin yang dihasilkan pada suhu 60°C memiliki rendemen gelatin sebesar 1,23%, pH 6, viskositas 0,399 cPs, kadar air 16%, kadar abu 1%, dan berdasarkan FTIR gelatin cangkang rajungan, gugus fungsi yang dapat diidentifikasi adalah OH, C-H alkana, C=C alkena, C=C aromatik, dan C-N.

Abstract

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. The program aimed not only to provide technical skills but also to increase environmental awareness and promote sustainable household practices. The implementation took place over three months (June–August 2025) using a participatory approach that included socialization, training, mentoring, and evaluation. 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.
