ORGANIC WASTE TRAINING FOR LIQUID FERTILIZER AND URBAN HOUSEHOLD CIRCULAR ECONOMY

Abstract

This article evaluates organic waste training for liquid fertilizer production in a dense urban neighborhood where kitchen waste remains mixed with residual waste. The activity addressed low source separation, dependence on municipal collection, weak composting habits, and limited knowledge of safe liquid organic fertilizer fermentation. The objective was to evaluate whether hands-on training can increase organic waste sorting, liquid fertilizer production skills, and household circular economy practices. A descriptive evaluative design with a one-group pre-test and post-test approach was used with 30 participants over six weeks. Data were collected through tests, observation rubrics, monitoring sheets, and reflection forms. The results showed improvement across four indicators: Sorting knowledge increased from 46 to 82, Fermentation skill from 39 to 76, Waste diversion from 31 to 62, and Circular practice from 35 to 71. Qualitative findings indicate that peer learning, guided practice, simple templates, and follow-up mentoring supported adoption. The study concludes that low-cost, practice-based assistance can strengthen local capacity when it connects technical skill with social support and simple monitoring routines.
