Abstract

Waste Cooking Oil (WCO) is the waste that came from household. WCO become a threat to community because it will come back to food chains again as residual bulk oil that have cheaper price than branded cooking oil. Lintas Winongo Waste Bank in Bumijo, Jetis, Yogyakarta City are trying to manage the waste cooking oil into recycled products. One of their products is aromatherapy candles. However, they had problem to produce the candles and sell it. They also faced problem about the odor of candle that came from WCO as raw material. The purpose of community service were to provide knowledge and skills to produce aromatherapy candles and to calculate the Cost of Goods Sold (CoGS). The methods in this activity were carried out in two stage. The first activity has organized by training and assistance in producing aromatherapy candles that mixed WCO and other ingredients. The second activity focused in calculating CoGS of candles. The results from these community service activities were increased knowledge and skills about producing aromatherapy candles. There were also increased knowledge about manage CoGS of their products

Abstract

Industrial and biological wastes are major contributors to environmental pollution and contain high levels of organic matter that can generate short-chain fatty acids (SCFA) through microbial fermentation. SCFAs are important not only as bioenergy precursors in industrial waste management but also as key biomarkers of gut microbiota activity in biological samples. This review provides a comparative analysis of analytical methods used to detect SCFAs in both industrial and biological matrices, focusing on High-Performance Liquid Chromatography (HPLC), Gas Chromatography with Flame Ionization Detection (GC-FID), and Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS). The findings reveal that HPLC—particularly Ion-Exclusion HPLC—is most effective for analyzing complex industrial waste samples such as waste-activated sludge (WAS) and palm oil mill effluent (POME), whereas GC-FID is more suitable for volatile-rich wastes like vinasse. Meanwhile, LC-MS/MS demonstrates exceptional accuracy and sensitivity for biological matrices such as feces, serum, and urine, allowing detection at ultra-trace concentrations. These insights underscore the need for optimized, waste-specific detection techniques to enhance environmental monitoring, waste valorization, and health-related SCFA research. Future studies should focus on developing rapid, cost-effective, and IoT-integrated detection systems to support real-time monitoring of both industrial and biological wastes.
