Abstract

The use of solar energy has become increasingly popular in recent years due to sustainability and environmental benefits. Universitas Samudra is designing the centralization of water distribution using solar energy as an energy resource. By using solar energy, universities can reduce their carbon footprint and energy costs while improving access to clean water for students, staff, and the surrounding community. This paper explores the benefits, challenges, design, and optimization of solar energy in pure water distribution, focusing on the technical and optimization of implementing such systems. The optimization is based on the water demand analysis and water source regarding the rainwater harvesting, then distribution points, including time patterns, peak demands, and seasonal fluctuation. The analyzing variables include the flow and residual head at each point distribution, pressure drop, pipe sizing, storage tank sizing, and water supply capacity input to each storage tank. The data is also based on the university's master plan and blueprint for the next 30 years of Development. Furthermore, the data will be analyzed and calculated to obtain optimum distribution pump capacity and pump working hours. The system was Analysed and calculated using Epanet hydraulic modeling software. The calculations result are that the distribution pump capacity is 16 L/s, the head is 30 M, the works for five hours a day, the power is 4.7 kW, the total energy is around 23.5 kWh per day, and The solar panel is eight kWp

Abstract

UIN Raden Intan Lampung is an Islamic university located at the southernmost tip of Sumatra. The area receives a rainfall ranging between 77-317 mm3 in 2022, and this rainfall must be harnessed and conserved as water reserves for daily needs. The university has a total area of 45 hectares, and it is home to a population of 34,482 individuals. The soil texture in the UIN Raden Intan Lampung campus area is predominantly clay, and the dense soil particles make it challenging to absorb water. Consequently, measures are required to regulate soil moisture levels to facilitate optimal water absorption. One strategy to preserve the water supply on campus is the construction of artificial ponds that capture rainwater. Ten such ponds have been built, covering 21.54% of the total green open space owned. Furthermore, around 8,000 biopore infiltration holes have been installed to maintain groundwater availability and improve soil fertility. The campus also conducts campaigns to promote water conservation and uses water-saving equipment technology. Treated wastewater from ablution activities in mosques is employed for secondary needs such as fish farming activities and irrigation. Ultimately, the preservation of water resources on campus must be sustainable, given the large population of people who depend on water for their daily needs, and ensuring water availability for the future is critical.
