The processing of markets’ organic wastes in Indonesia, especially in Yogyakarta, is still done conventionally, that most of it, is directly composted at the Landfill or sometimes even directly dumped without going through the composting process. This research was conducted to maximize the processing of the organic waste that was generated by the local market, using continuous flow bin and vermicomposting to make it more economically beneficial to the community and to test the chemical parameters like Carbon / Nitrogen, Phosphor, and Potassium level from the vermicast, which is the after-product of vermicompost process. The research process goes through several stages: the acclimatization stage, the feeding stage or the vermicompost process, and the testing stage. Carbon/Nitrogen ratios, Phosphor, and Potassium values in the final results of the three reactors in the composting process meet the composting criteria according to SNI 19-7030-2004. The Carbon/Nitrogen measured in the three reactors were 10.2%, 16.6%, and 11.54%, respectively. The phosphorus levels (P) available in the three reactors were 0.32%, 0.35%, and 0.33%. Potassium (K) levels available in the three reactors were 0.26%, 0.58%, and 0.67%. The K values in reactors 2 and 3 meet the compost criteria or standards from SNI 19-7030-2004 because it is more than 0.20%, while for reactor 1 it is still below the criteria standard.
