Abstract

Penelitian ini merupakan penelitian pengabdian masyarakat dalam memanfaatkan limbah minyak jelantah sebagai bahan baku pembuatan sabun padat. Hal ini bertujuan untuk mengurangi limbah minyak jelantah dan memberikan edukasi mengenai pengolahan minyak jelantah menjadi produk yang bernilai ekonomis. Objek pada penelitian ini adalah siswa dan siswi SMPN 16 Malang dari ekstrakurikuler OSIS dan KIR. Metode yang digunakan yaitu ceramah dan diskusi untuk memberikan pengetahuan bahaya minyak jelantah, praktik dan demonstrasi dalam pembuatan sabun padat dari minyak jelantah serta evaluasi untuk mengukur efektivitas pelatihan dengan melakukan pre-test dan post-test. Hasil kegiatan menunjukkan bahwa siswa dan siswi sangat antusias dalam memahami materi yang disampaikan dan berhasil mempraktekkan pembuatan sabun padat dari minyak jelantah secara berkelompok dengan baik. Berdasarkan survei kepuasan, 90% responden menyatakan sangat puas terhadap pelatihan pembuatan sabun padat dari minyak jelantah. Selain itu terdapat kenaikan sebesar 34% dari hasil pre-test dan post-test yang diberikan. Maka dapat disimpulkan bahwa penyampaian materi terkait cara mengurangi limbah minyak jelantah menjadi barang yang bernilai ekonomis kepada siswa SMP efektif untuk dilakukan dan dapat diterima dengan baik. Kata kunci— Minyak Jelantah; Sabun Pada; Siswa SMP; Pengabdian Masyarakat

Abstract

Water is one of the most fundamental basic needs for human life. However, disparities in the availability of clean water remain a significant challenge in Indonesia. This study aims to develop a water purification device to address this issue. The research method employed was the ADDIE model, which consists of five stages, with this study focusing on analysis, design, and development, which serve as scope of this study. The result of a water purification, named HydroTechPure, utilizes a dual filter system with high quality absorbent materials and is constructed from acrylic materials, enhanced by 3D design technology and Arduino integration. The development of this device aligns with the sixth goal of the Sustainable Development Goals (SDGs), which emphasizes ensuring access to clean water and sanitation for all. HydroTechPure was developed at FabLab Edu UPI. Beyond its primary function, HydroTechPure is envisioned as a tool for integrating STEM based learning, aiming to foster students’ motivation and environmental awareness.

Abstract

This study aims to measure the content validity of an AI-based automatic assessment system for scientific literacy instruments on green chemistry integrated with ethnochemistry using Aiken’s V index. The research design adopts the R&D model with the ADDIE approach, limited to the analysis, design, and development stages. A combination of quantitative and qualitative descriptive methods was utilized through purposive sampling, engaging 10 experts—chemistry education lecturers from UNS, UNY, UM, and high school chemistry teachers in Surakarta. Data were obtained through Focus Group Discussions (FGD), focusing on three aspects: context, language, and construct. Essay-based instrument items were rated using four relevance categories: irrelevant, less relevant, quite relevant, and relevant. Items with an Aiken index ≥ 0.73 were considered valid. The results showed that 1 question item had moderate validity and 14 question items had high validity, making them suitable for further testing. The questions were designed to assess students’ understanding of green chemistry principles and their ability to relate these to ethnochemistry practices—local cultural knowledge that supports sustainability. The formulation of the questions also demonstrated how the application of local culture can be interpreted through green chemistry to enhance scientific awareness and environmental responsibility. Based on the content validation results and subsequent revisions, the instrument is deemed ready to move forward to the limited trial stage.
