RANCANG BANGUN TEKNOLOGI "DIGESTER" GAS BIO UNTUK MENGATASI KETERBATASAN ENERGI PERDESAAN DI DESA KEDUNGDOWO, KECAMATAN ARJASA, SITUBONDO, JAWA TIMUR

Design of iechnology "digester" to overcome the limitations of Bio Gas Energy Kedungdowo rural village, District Arjasa, Silubondo, worked in a Pilot Scale Plant with biomass raw material/Cow manure (Digester capacity of 3500 kg I Botch). This study aimed to study the effect of cow manure and water ratio end the number of microbial processes are added. The reactor used is the type Fited Dome (Fixed Dome) equipped with barriers and the piston which serves to keep the fluid turbulence (slurry) in a reactor. Biogas Production process is run on a variety of cow dung with water ratio and the number of microbial processes are added. Fermentation process is run for 16 days per batch by varying the variables that run. Furthermore, the hose 4 (four) days was observed, measured and recorded 1:1 the Reactor Pressure Digester, gcs products and analyzed the gas content is formed. Relatively good results obtained in cow manure and water ratio of 1 : 1 with the addition of 50 ppm with microbial fermentation time for 12 (twelve) days that produce products m3/Batch with 5.1 Gas concentration Methane Gas (CH4) in the range 74%, Gas Dioksid Carbon w'ioxide (C02) 19%, and Gas Time 7%. Product Biogas can be used to meet the needs of everyday household. It also tested for energy for rural electri
