Abstract

Compressors and compressed air systems are important areas for improving energy efficiency in industrial plants. The compressor engine is one of the machines that are included in the top 5 machines with the highest energy consumption. Based on the results of the analysis, the old compressor with a capacity of 90 KW only had a load of 70%, so another 30% wasted energy during the unload condition. The compressor engine which previously used high enough energy was replaced with a compressor engine type AF OPC 55-10 which uses more energy efficiently than the previous type because its capacity is only 55 KW. Through the use of this compressor, the compressor load can reach 90% and is more efficient in energy use. Thus, the potential for energy savings from the utilization of the compressor engine, reaches 306,600 kwh/year. or a potential cost savings of Rp. 442,945,020 per year. With a temperature of 50oC when operating (load) the motor output power is 193 KW and when not operating (unloaded) at a temperature of 45oC the motor output power is 186 KW from the nameplate data of 200 KW. The percentage of leaks in the compressed air system on the blow molding machine is > 10%.

Abstract

Hindu religious ceremonies in Bali in their implementation produce a lot of banten waste. Banteng waste is difficult to decompose as compost. Utilization of waste as fuel or Refuse Derived Fuel (RDF) is one option in overcoming the problem of waste waste in Banten in Bali. There are various processes that can be applied to produce RDF, including through biodrying. Biodrying is one part of Mechanical-Biological Treatment technology which aims to reduce the water content of waste by utilizing the heat generated from the activity of microorganisms in degrading organic matter so that an increase in calorific value is expected. RDF refers to the separation of the fraction which has a high calorific value from the separation process. RDF production is designed to convert the combustible fraction of municipal solid waste into fuel. In the process of making RDF, the residual waste from the former offerings goes through various stages of heating and printing. The resulting RDF is of high quality and has been tested with a yield of 4.000 kcal/kg. The finished RDF can be used as fuel, one of which has been used as boiler fuel in a laundry business in Badung Bali. The use of RDF can replace non-renewable energy sources that have started to run out and are replaced with new renewable energy with the concept of waste to energy.
