Karakterisasi Kompos Hasil Dekomposisi Sampah Organik Perkotaan dengan Biodekomposer EM4, Orgadec dan Biodek

Abstract

The research is to examine characterization of compo~t on the production of municipal organic waste decomposition with biodecomposer of EM4, Orgadec, and Siodek. This organic waste was chopped, ther:l it was mixed with biodecomposer Clnd put Il1tO composting container. The parameter it self consist of the change of temperatur, pH, humidity, ratio oi C/N, mineral content and heavy metal. The result of CClmposting of municipai oiganic waste to indicated that blodecomposer of EM4 (K2) is better than Orgadec (K1), Biodek (K3), and unbiodecomposer (KO). The result of this analysis of the change temperature on the 1.1 day is ir.dicated the increment of the temperature for aU corl'lposted, and the highest temperature were analyzed at the treatment K2, the average is starting from 32.17 to 49.17 °c. All of the pH average trend was increased after 3rd days, and it was decreased afterwards. The pH decrease of it self quite significant at treatment K2 there was 8.30 at 3rd days and 7.07 at 7th days. At 10th days, composting and all treatment indicated that reduce of the raw materials of compost. The highest reducer of the raw materials of compost was analyzed at K2 treatment is 24.88% compare with the average treatment which is valeu 18.85'0' The result of the research on 30th days of composted, only K2 treatment produce done compost, the characteristic consist of the average is ratio of C/N 10.67, temperature of 27.S7 °c, humidity of 73%, crumbs characteristic with color brown and blackies. On other hand, the mineral content and heavy metal on the compotiting Standard
