Prospek dan Potensi Biogas sebagai Energi Alternatif Menghadapi Krisis Energi
Energy plays an important role in almost all human activities and cannot be released in human life. Excessive utilization of non-renewable energy can create energy crisis problems. Biogas is a gas resulting from the fermentation process of organic materials. These organic materials, for example, manure, agricultural waste, kitchen waste, and Biogas organic waste are produced by bacteria from organic matter in vacuum (anaerobic) conditions. Biogas consists of methane (CH4) 50 – 70%, carbon dioxide (CO2) 30 – 40%, and other gases with a small percentage. At the end of the fermentation process, biogas is produced which can be used as fuel and power generation, heat that can be reused, and the remaining decomposition of raw materials for making biogas can be used as fertilizer for use in agricultural land and plantations. The potential for biogas development in Indonesia is still quite large, considering the large number of farms in Indonesia and the large amount of household waste that can be used as raw material for making biogas. The use of organic waste into biogas plays an important role in waste management because it reduces direct generation and reduces the greenhouse effect indirectly because compare to carbondioxide, methane contribute more in increasing the green house effect.

Large rainfall is a great potential in supporting various needs for farming, raising livestock, daily needs to meet the needs of electric power. On the other hand, high rainfall also has the potential to increase the occurrence of floods, especially if the rains that occur last for a long period of time. Flooding is also affected by the soil's ability to absorb a certain amount of rainwater that falls. Soil absorption or infiltration is influenced by various causative factors, such as land use patterns dominated by concrete structures, low levels of lengas in the soil, or loss of vegetation on the land surface and water storage capacity and drainage systems that are not optimal. To solve this problem, PT Semen Baturaja, created an artificial swamp. There are 4 (four) artificial swamps located in the area of PT Semen Baturaja. An artificial swamp is a pond-shaped excavated land that is made as a substitute for the function of the infiltration land which is estimated to no longer be able to carry out its function optimally due to various reasons. For example, closed land, infiltration land that has changed its function to become residential and office areas and several other causes. The main function of artificial swamps is to withstand the large rate of flood peaks in the river so that the overflow of clove water (over topping) can be reduced to avoid embankment failure. Another important benefit of artificial swamps is as a water saving (water conservation) with increasing groundwater reserves at the site
