The increasing consumption of fossil-based energy especially LPG (Liquid Petroleum Gas) that is not balanced with the availability of energy source, required a development of alternative energy with abundant amount and environmentally friendly. One of alternative energy source feasible to develop is the one from biomass waste that is livestock manure. Magelang becomes one of potential area in Central Jawa as biogas development. Biogas is produced by using digester anaerobically. Magelang has livestock about 142.127 with potency of gas production about 86.690 m3. The resulted biogas production equals to 43.345 kg of LPG or 14.448 of LPG 3 kg which is can fullfill the cooking needs for about 278 households in one year.

Coconut Coir

Biomass waste can be used as raw material for bio-oil manufacture. One of the biomass is coconut coir and shell waste, commonly used as a substitute for firewood and handicraft materials. Therefore it takes effort to use coconut coir and shell to increase its economic value. One of the waste processing efforts is through pyrolysis process. Pyrolysis is the heating process of a substance in the absence of oxygen and produces products of solids, liquids and gases. The product of pyrolysis liquid is called bio-oil which can be used as alternative energy source. In this study, coconut coir and shell was pyrolysed as bio-oil. It also studied pyrolysis operating temperature and the amount of yield of bio-oil produced. The pyrolysis process was carried out in a reactor with a pressure of 1 atm and a varying operating temperature of 150 °C, 200 °C and 250 °C for 60 minutes. The reactor was equipped with a condenser as a cooling column. The mass of raw materials used was 500 grams with a size of 0.63 mm. The results of the research show that the higher the temperature, the more volume of bio-oil produced. For coconut coir pyrolysis it was obtained the highest yield of 34.2%, with density of 1.001 g/ml and viscosity of 1.351 cSt. As for coconut shell pyrolysis it was obtained highest yield of 45,2% with density of 1,212 g/ml and viscosity of 1.457 cSt. From the result of analysis using FTIR, the functional group of bio-oil was the most compound of phenol and alkene.

This article covered a wide range of questions on the topic of production and use of biogas as alternative energy source. Biogas is produced by anaerobic digestion of biomass due to the breakdown of fats, proteins and carbohydrates, which constitute the bulk of organic matter. The article describes the most common methods of biogas production, their stages and characteristics. In addition, the article describes some of the possible areas of application of biogas on example of different countries. The article also provides information about key environmental and economic benefits in the case of use of biogas: prevention of methane emissions and lower emissions of carbon monoxide and nitrogen oxides into the atmosphere; the possibility of using secondary raw materials to generate electricity.

Tofu wastewater is a pollutant when discharged into the aquatic environment because it can cause foul odors, diseases and reduce the concentration of dissolved oxygen. On the other hand, tofu wastewater can be used as an alternative energy source, namely biogas. The study aims to determine the effect of fermentation time, substrate ratio and stirring on biogas production and methane gas. Variables used in the experiment included: volume ratio of starter (10, 20, 30, and 40% ); stirring (1, 7, and 14 days), fermentation time (5, 10, 15, 20, and 25 days). The research was conducted using a digester that has a volume of 50 liters filled with starter as much as 10, 20, 30 and 40% (v/v). Then the digester is flowed with N2 gas until the digester is in anaerobic condition then stirring (1, 7, and 14 days) or without stirring. Every 5 days to 25 days a sample is taken and the amount of biogas and methane gas produced is measured. Measurement of methane gas concentrations using a gas analyzer. The experimental results show that the highest volume of biogas and methane gas produced during fermentation time of 20 days, with a stirring of 14 days, and a starter of 30% which can produce biogas and methane gas respectively of 5,000 ml and 540 ml.

The study was carried out to find out if it is feasible to use guinea pig excretions for the generation of biogas as an alternative energy source at altitudes above 2,500 meters above sea level. Two types of biodigesters were investigated, one discontinuous and the other Taiwanese. The biogas was subjected to a gas chromatography analysis, which showed the concentration in weight and moles of CO2, methane, nitrogen and water, relative density, molecular weight and caloric value. The gas from the discontinuous biodigester was the one with the best results, since its composition had 50.10 % mol of methane.
