Abstract
Biogas is renewable energy that can be seen from technical, economic, and social aspects which can be used to supply energy that comes from fossil fuels. Biogas contains methane (CH4) and carbon dioxide (CO2) as well as several other gasses, namely hydrogen sulfide (H2S), ammonia (NH3), hydrogen (H2) and nitrogen (N). Biogas can be made from livestock waste such as animal manure by ruminants, pseudoruminants and non-ruminants. Therefore, this study aims to compare the quality and quantity biogas before and after purification from different types of animal manure by condensation and multilevel adsorption method. Types of animal manure used in the research by cow dung, rabbit manure, broiler manure, and mix manure. The study was conducted in 7 treatments, namely cow dung (T0), broiler manure (T1), rabbit manure (T2), cow dung+broiler manure (T3), cow dung+rabbit manure (T4), broiler manure+rabbit manure (T5), and cow dung+broiler manure+rabbit manure (T6). Then all treatments will be purified with condensation and multilevel adsorption methods with 5 different adsorbents (roof tile waste (RW), CaO (CO), activated carbon (AC), Fe powder (FP), and zeolite (Z)). The methods were the preparation of feedstock, purification tools, biogas production. The parameters measured were volume, pressure, and biogas content before and after purification. The research design used was a Completely Randomized Design (CRD). The results obtained were tasted by One Way ANOVA followed by DMRT Test with a confidence 95% (α-=0.050. Furthermore, the effect of different types of animal manure on quality and quantity biogas is the highest CH4 and lowest CO2 content resulting from purification using A3 treatment of 98.73% CH4 and 0.70% CO2 with T6 (mixture of 3 animal manure). However, the pressure, flow rate and volume of biogas with different types of waste have different values every week.
