PENGARUH PENAMBAHAN KULIT ARI KEDELAI TERHADAP PROSES PENGOMPOSAN SAMPAH ORGANIK PASAR DENGAN BIOAKTIVATOR EM4

Market is a place which couldproducethe organic waste in the number that was sizable. At Kulon Progo's Regency this waste from market had not been utilized yetthat it could cause pollution. Inthe other ones, agricultural farms got decreasetheirfertility zoom, becausethe farmers really cling to chemical manure and pesticide. One of the ways to settle both of about this problem wasby passing through composting process. The goals of this research were to knew how to influence the addition epidermis of soybean (Glycine maxepidermis) on the variousweights to organic waste from the market composting process, and knew the content of C, N, P, K, C/N ratio, pH, and water content of compost that wereproduced from organic waste from the market composting bases default (SNI 19-7030- 2004). This market organic waste was wet waste, so for composting it needs added by bulking agent that one of it is cow filt and also bioactivator. Bioactivator thatwas utilized in this research was EM4 1%, suitable to the label on the bottle. On this research it also addedepidermisof soybean as source of Nitrogen in composting process. Each day material of compost was measured its temperature and pH, meanwhile water content measurement and C/N ratio was done each 7 days. The temperature ofcomposting on the research result was first t = 30ºC, then temperature peaked on the conduct, continously are: 38ºC, 45ºC, 44ºC and49ºC. Temperature started down stables on 29th day and until the temperature 35th day it was as big as t = 30ºC. The appreciative C/N ratio without addition of soybean epidermis, with addition of soybean epidermis 10%, 20%, and 30% continously were: 15, 13, 13, and 11,had suited to SNI 19-7030-2004 was 10�20. The content of C, N, P, K, water content, and pH of compost hadsuitedwith SNI 19-7030- 2004 on the comparationC, N, P, K, water content, pH and C/N ratio with SNI 19-7030-200
