Biogas is a gas produced from biological activities in anaerobic fermentation process and as a renewable energy. This research is to find out the effect between elephant manure, elephant urine,water and starter to reduce biogas production and assess kalor. This research divided into three groups based on the row material, i.e., elephant manure, elephant urine, water and starter as independent variabe. Observation consist of volume of biogas production and assess kalor. This result showed that 4 kg raw material in 21 days, elephant manure mixture with elephant urine (1 : 2) is the best raw material to produce biogas reached 60800 ml and assess kalor reached 5345,39 kal/lt. elephant manure with elephant urine and water can also prodece biogas, but it is a little reached 20907 ml and assess kalor 4785,69 kal/lt.
