Composting with the conventional method takes a long time so it is less effective to overcome the problem of accumulation of organic waste. Therefore, it is necessary to find another method or method of composting that is more effective to overcome this problem. Currently, it has been found EM4 (effective microorganime 4) by Prof. Teruo Higa from Japan's Ryukyus University. This EM4 solution contains fermenting microorganisms and can work effectively in accelerating the composting process compared to conventional methods. According to Mirwan's research in the journal Environmental Engineering Vol. 04 No.01 which uses aeration and cow dung with the final result of C/N quality compost of 4.144. However, from these studies, the quality of the compost formed for the C/N ratio parameter has not met the C/N ratio standard according to the SNI 7763:2018. Therefore, the aim of this research is to analyze the performance of composting from organic waste using EM4 and cow dung using the takakura method with sieve diameters of 3 mm, 4 mm and 5 mm. In this way, it is hoped that the composting process can run more effectively and produce quality products. The results of the study on the effectiveness of compost processing with a sieve diameter of 3 mm with composting time of 15 days, yielded Organic C of 31.12%. Macro Nutrients (N + P2O5 + K2O) 4.51%. C/N 20.49. And the average pH was 6.6–7.3. The results of the study on the effectiveness of compost processing with a sieve diameter of 4 mm with composting time of 15 days, yielded Organic C 31.12%. Macro Nutrients (N + P2O5 + K2O) 5,46%, C/N 20. And the average pH was 6.6–7. The results of the study on the effectiveness of compost processing with a sieve diameter of 5 mm with composting time of 15 days. Yielded Organic C 31.05%, Macro Nutrients (N + P2O5 + K2O) 6 .56%. And the average pH was 6.6–8. The quality of the compost in this study complied with SNI 7763:2018. Leachate as much as 4 l on a sieve diameter of 3 mm, a sieve diameter of 4 mm as much as 5.5 L and 6.5 L in a diameter of 5 mm. Days compared to the composting time of 20 days and 25 days. Leachate produced from the composting process needs to be analyzed to determine the quality of Nitrogen, Phosphorus and Potassium (NPK) leachate, so that leachate can be used as liquid fertilizer.
