Waste Power Generation System at The Institute Technology of Sumatera, Lampung, Indonesia

The Sumatera Institute of Technology (ITERA) is a public university based in Jati Agung, South Lampung Regency, Lampung Province. Based on the assignment from the Ministry of Education and Culture, in the early stages of development and implementation it will be carried out by the Bandung Institute of Technology in collaboration with the Regional Governments throughout Sumatera. Furthermore, on October 6 2014 and promulgated on October 9 2014, the Sumatera Institute of Technology (ITERA) was established. One of them is pollution, including water, air and land pollution. In general, most of the waste produced at ITERA is domestic waste, accounting for 20-30% of the total waste volume. The objectives of our study are (1) to determine the quality and quantity of ITERA solid waste (2) to identify potential solid waste into environmentally friendly energy. Data processing and analysis is carried out descriptively based on the data that has been obtained, then the data is processed by calculating the potential for waste to become electrical energy. Waste generation data is needed to calculate the amount of waste stock that will later be used as fuel and will be related to the continuity of electrical power supply and the amount of energy that will be produced (KWh) and calculate the amount of energy potential. Quality and quantity of ITERA solid waste are food waste has the largest percentage, namely 24.11%, where the largest composition comes from food waste. The high level of food waste produced is due to students' habits of consuming excessive food without managing the waste. The total projected waste generation at ITERA in 2022 is 528,428 kg/day or 3,236 L/day. Calorific value is found in food and market waste, namely 1,295.98 Kcal/kg. The Potential production results from the direct combustion (Incineration) technology process carried out by PLTSa produce a potential electrical power of 1,862.6112 kWh/day, if operated for 1 year the potential electrical power produced is 679,853,088 kWH/year or 679.85308 MWh/year.
