Abstract

The Kreasi Tani Group in Bunton Village, Cilacap Regency, faces two main challenges in developing oyster mushroom cultivation and pioneering shallot cultivation. First, the significant water requirement for mushroom spraying and shallot seedling watering causes quite burdensome electricity costs for water pump operations. Second, the farmer group does not yet have an adequate financial bookkeeping system, making it difficult for them to accurately monitor financial conditions and make strategic considerations for future business development. This community service activity aims to implement two technological solutions. The first solution is to design and install a Solar power plants system to operate the water pump. Solar power plants system uses 2 200 Wp photovoltaic units, 1 1500 VA inverter unit, and 2 60 AH batteries. The second solution is to develop and train the use of an Android-based mobile bookkeeping application (created with MIT App Inventor) designed to record production results, prices, and summarize sales results of oyster mushrooms and shallots periodically (weekly or monthly). The implementation of Solar Power Plant system can significantly reduce production costs through electricity savings. Meanwhile, mobile bookkeeping applications make it easier for managers to create financial reports, provide accurate data sources, and support strategic decision-making for future business development.

Abstract

Indonesia has a large solar energy potential, with an average radiation of 4.5-4.8 kWh/m² every day. Politeknik Negeri Cilacap (PNC) can take advantage of this opportunity to develop a Solar Power Plant. This study examines the possibility of building an on-grid rooftop solar power plant in the Department of Electrical and Mechatronics Engineering. This study uses Homer to simulate the solar power plant design. The parameters discussed are total energy production (kWh/year), renewable fraction, net present cost/NPC (Rp) which is all costs used in construction, both in installation and operation of the solar power plant and Cost of energy/COE (Rp/kWh) which is the cost incurred to produce electrical energy per 1 kWh. The results of the study include an average solar energy at PNC of 4.66 kWh/m²/day. Based on Homer's simulation results, the total energy generated by the solar power plant is 149,056 kWh/year, with 68,599 kWh/year from photovoltaic and 80,457 kWh/year from the PLN grid. The renewable fraction is 44.8%. The NPC is Rp 1,880,000,000, and the CoE is Rp 1,000/kWh.
