Abstract

This study is motivated by the high consumption of cooking oil in the Micro, Small, and Medium Enterprises (MSMEs) sector, which is often constrained by operational costs, triggering the repeated use of waste cooking oil (jelantah) that poses carcinogenic health risks. This study aims to design and build a portable waste cooking oil filtration machine for households/MSMEs to provide a preventive solution to health risks while supporting economic efficiency. The research method uses a Participatory Ergonomics approach, involving active stakeholder participation including users, chemists, and manufacturing practitioners in identifying design needs. The design development results transformed the initial concept relying solely on gravity into an integrated four-stage purification system, namely: initial filtration using 100 mesh, heating process to reduce viscosity, water and odor absorption using zeolite adsorbent, and final filtration. The realization of the prototype with dimensions of 36 × 35 × 67 cm shows that this system is effective in separating solid contaminants, reducing water content and rancid odor, and producing visually clearer and usable oil. However, this study is limited to qualitative evaluation of oil clarity, odor, and water content reduction, and has not yet included quantitative laboratory analysis of free fatty acid levels.

Abstract

Visually impaired students in Banyumas face significant challenges in accessing inclusive education due to the scarcity of adaptive learning media. Most students rely heavily on conventional Braille and constant teacher assistance, which hinders their independent learning capabilities. This community service aims to empower teachers and students at SLB Kuncup Mas Banyumas through the socialization and training of BraillTek, a bilingual RFID-based assistive device designed to support independent literacy. The method employed was a participatory approach involving 30 participants, consisting of teachers and students. The activities were conducted on December 9, 2025, encompassing socialization of disability rights, direct demonstration of the device, and hands-on training where students practiced using BraillTek while teachers were introduced to AI-based educational tools. The results indicated high program effectiveness, with evaluation data showing that 100% of participants agreed the material was highly relevant to their needs. Students demonstrated the ability to operate the device independently after a single session, effectively learning vocabulary without constant supervision. The program successfully introduced a viable solution for inclusive education, significantly reducing student dependence on teachers and improving teacher competency in utilizing assistive technology.
