Food waste is organic waste, the most significant component in Indonesia, which can be processed as raw material for composting. The composting process can be accelerated by adding an activator. Therefore, this study was conducted that utilized household food waste with the composition of leftover rice, leftover vegetables, and fruit peels as raw materials for composting to compare the compost yield with the addition of a bio activator of local microorganisms (LMO) with effective microorganisms (EM4) using the Takakura method. Composting was carried out in duplicate with five variations, namely, a variation I without the addition of activator, variation II EM4 activator, variation III LMO a mixture of tuna fish waste and shrimp waste plus leftover vegetables, variation IV LMO a mixture of coconut coir and leftover vegetables plus tuna fish waste, and variations V LMO a mixture of tuna fish waste and shrimp waste plus a mixture of coconut coir and leftover vegetables. The results showed that the maturity test (pH, temperature, color, texture, smell, humidity, and time of composting), and the quality test included physical elements (water content, pH, temperature, color, texture, odor) and macro elements (C-organic, nitrogen, C/N ratio, P2O5, and K2O) have complied with compost standards according to SNI 19-7030-2004. The result of the quantity test showed that mass reduction in the range of 46.97-53.46%. Based on the results of the scoring on the analysis of maturity, quality, and quantity, the best variation was found, namely variation V, with the fastest composting time of 11 days, and the compost yield was 4.6 kg from 9.24 kg of the initial weight of compost raw material with a mass reduction rate of 50.22%.
