Abstract

Electrical energy used in Manokwari, West Papua, is still dominated by fossil energy sources. One of the efforts to reduce the use of fossil energy is to utilize potential renewable energy sources in Manokwari. One of these sources is solar energy with irradiation of 4,859 kWh/m²/day. Rooftop PV is one application of the use of solar energy. In this study, the design of the rooftop solar power plant in the Faculty of Engineering, University of Papua was simulated using EasySolar and PVSyst software. With an azimuth angle of 36°, a roof slope of 35°, a roof area of 1,184.94 m², and an installed power of 66 kWp, it takes 220 panels with a capacity of 300 Wp, 2 inverters with a capacity of 33.3 kW. The layout of PV module on the rooftop is simulated using EasySolar software resulting a total of 220 modules on required a roof area of 594 m². In the simulation output using PVsyst software, it is obtained 99.07 MWh per year and the percentage of savings per year is 102.5%.

Abstract

The AFL (Airfield Lighting System) is a crucial part of the airport infrastructure that plays an important role in supporting aircraft operations. Using LED type lights allows for more efficient energy use and has a longer service life. Of course this would be an effective solution to dealing with energy waste. In this study this time will discuss the comparison of light intensity, and comparison efficiency of electric energy use of LED lamps with halogen lamps at Manokwari Rendani Airport, and Comparison of the cost of electricity consumer of LED light to halogen light at Manokwari rendani Airport. The power of the halogen lamps is 2.239.25 cd, while the light of the LED lamps with a reflection factor of 0.98 is 6.539.05 cd. This results in a threefold comparison between the alpha taxiway and the bravo taxiway. The use of halogen lights costs Rp. 3.557.429,28 per year, whereas the use of LED lights requires electricity costs of Rp 1.185.809,76 per year. You can see that the use of bravo taxiway lamps with LED type is more efficient in terms of energy consumption, light intensity and cost effectiveness compared to alpha taxiway lights with halogen type
