<![CDATA[The ECOLORA (Eco enzyme for Environmentally Friendly Household Waste Processing) program aimed to improve the knowledge and skills of residents in RW 02, Nginden Jangkungan Village, Surabaya, in managing household organic waste. The program involved 20 participants consisting of housewives and micro, small, and medium enterprise (MSME) actors. The implementation methods included educational sessions, demonstrations and hands-on eco enzyme production, discussions, and evaluation using pre-test and post-test instruments. The results showed increased participant knowledge across six assessment indicators. The proportion of correct responses increased from 25–65% in the pre-test to 100% across all indicators in the post-test, with an average increase of 49.17 percentage points. The largest improvement was observed in understanding the fermentation process, which increased by 75 percentage points. The program demonstrates that participatory training can improve community knowledge of household organic waste management.]]>
