Solar Powered Peat Water Treatment Model for Achieving Sustainable Clean Water Independence at Nurul Jadid Islamic Boarding School Kubu Raya Regency

Abstract

Nurul Jadid Islamic Boarding School in Kubu Raya Regency is a social educational institution that provides free education for orphans and underprivileged children Its location within a peatland area presents significant challenges for clean water provision as the groundwater is acidic dark in color rich in organic matter and bacterially contaminated Limited electricity access further increases operational costs highlighting the need for an efficient economical and renewable energy based treatment system This study aims to design a solar powered clean water treatment plant WTP tailored to peat water characteristics and to prepare a cost estimation RAB for technical and financial planning

A quantitative approach was employed including water demand analysis raw water quality testing in accordance with Ministry of Health Regulation No 2 of 2023 design of treatment units in compliance with SNI 6774 2008 and estimation of investment and operational costs The findings show that the pesantrens water demand is 1 62 L per second 139968 L per day The treated water complied with drinking water standards with turbidity reduced from 107 NTU to 2 4 NTU color from 545 TCU to 5 12 TCU iron concentration from 5 71 mg per L to 0 23 mg per L and pH increased from 6 2 to 6 86 E coli and Coliform were completely eliminated 0 CFU per 100 mL From the energy perspective a 3 2 kWp solar panel system eight 400 Wp units generated 9 kWh per day with a 12 to 15 kWh battery reserve sufficient to meet the WTPs 1 5 kW demand The initial investment of IDR 178 1 million and a monthly operational cost of IDR 1 2 million confirm the technical and economic feasibility of sustainably providing clean water at the pesantren
