Waste management in West Nusa Tenggara Provincial Government focuses on two main things, namely the reduction and handling and providing of TPA which is still operated with an open dumping system. Application of an open system in TPA will cause many problems, including air pollution by methane gas and the greenhouse effect. This study aims to determine the potential methane gas content of the Kebon Kongok landfill as an alternative energy source by modelling using LandGEM. The data in this study consisted of the year of the TPA operation plan and the annual data on the waste generation of TPA. The results showed that the potential content of methane gas was 12,999,633.62 m3/year, or equivalent to 14,520.88 MWh/year, in the form of gas as much as 9,966.38 Megagrams of LPG/ year. Therefore, the Kebon Kongok TPA has the potential to be used as a power plant fuelled by methane gas and facilitates electricity connections for the surrounding community because when compared to other existing renewable energy plants in the Lombok Electricity System, the capacity of 1.66 Megawatts was already  equivalent to the power generation  capacity which are already operating commercially.

<p>Supit Urang landfill is landfill that collected and used methane as an alternative energy source. Methane gas was produced by garbage in dumped in landfill which undergo decay and under certain conditions. Therefore, the main purpose of this study is to measure the GHG emission reduction from the landfill through scavenging and distribution methane gas as alternative energy. The reduced waste tonnage was calculated for its GHG emission using methane emission calculation formula proposed by IPCC. Scavengers in Supit Urang landfill contribute to reduce 2, 3 % of paper, plastic and glass for about 0, 23 %, 0, 88 % and 0, 72 % respectively. The fraction of degradable waste sorted by the scavenger contribute to the GHG emission reduction for about 0.12 %. In 2018, estimate of potential methane gas are 5 828,90 ton CH4 and it will distribute to 319 households surrounding Supit Urang landfill as a fuel to cook. Manage the methane can reduce the risk of gas explosion and also can be solution to solve crisis of energy. Methane is a renewable energy, but just 0,7 % from total methane gas from Supit Urang Landfill that used by public. <br /><strong></strong></p><p><strong>Keywords</strong>: alternative energy; garbage; landfill; methane; reduce; scavenge</p>

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.

Energy harvesting through motion caused by wind is a unique way of finding an alternative energy source for several electronic devices. Piezo-electronic sensors, which harvest energy from small vibrations and movements, are investigated by many researchers nowadays. This paper conducted an experimental study to find an alternative energy source for diverse electronics with forced oscillations from a fan. The relations between the force applied by wind and the oscillation of a paper strip were studied.
