Abstract

The composting process commonly takes place within the quite long time, thus the Purpose of this Research was intended to accelerate the composting time and to obtain the good compost quality with the activator use concentration as efficient as possible. In this research the Composting Process was conducted in the lab scale using the mixture between the EM4 activator and Star Bio by staged method with the proportion of activator use 1 : 1 in which the activator use volumes variable were as much as 60 ml, 70 ml, 90 ml, 100 ml and the times variable researched were 5,10, 15, and 20 days with the aerobic process. Of the analysis results obtained the activation use concentration of 100 ml was effective to lower the C/N ratio (compost maturity level) from the initial C/N ratio concentration of 58 dropped to 11 in the composting time length of 10 days with the contents of organic C (37.13), N value(3.43), K value (1.19) and P value (9.4). This case indicated that the obtained results were good enough. Due to it has already entered in the SNI standard 19-7030-2004. Key words : Compost, EM4 and Star Bio combination, staged method
