In this study, the temperature probe is assembled to control temperature of compost is in the optimum range 55 C to 65 C .

This is because most of the studies reported that the optimum temperature range for effective decomposition was at 50 C to 70

C. In thermophilic temperature, the dominant micro-organisms might attack rapidly soluble readily degradable compounds,
high content of available nutrients and relatively small size of organic fraction particles. It is also reported that composting

above 55 C could kill pathogen and sanitize the compost. Temperature of the composting must be below 75 C because higher
temperature cause denaturation of enzymes in microbial cells. (Mohd Ali Hassan et al 2010)
