ANALISIS WATER CREDIT PADA UNIT PRASARANA KONSERVASI AIR DI DAERAH ALIRAN SUNGAI (DAS) PRUMPUNG, KABUPATEN TUBAN, JAWA TIMUR
Abstract: Water credit is the
activity to increase groundwater by increasing infiltration. The purpose of
this research were to design and to analyse water credit of water conservation
infrastructure unit in Prumpung DAS. The research consisted of prediction
rainfall analysis, designing and water credit analysis of each water
conservation infrastructure. The result showed that water credit of single
artificial well unit were Rp 6.160.832 to Rp 9.555.674 per m3/year for
mediterranean soil, Rp 30.804.158.249 to Rp 47.946.013.645 per m3/year for
grumosol soil, and Rp 10.589 to Rp 16.464 per m3/year for regosol soil. Water
credit of communal artificial well unit were Rp 10.498.475 to Rp 11.200.082 per
m3/year for mediterranean soil, Rp 52.492.374.552 to Rp 56.443.974.147 per
m3/year for grumosol soil, and Rp 17.426 to Rp 19.194 per m3/year for regosol
soil. Water credit of rorak unit were around Rp 198.701 per m3/year for
mediterranean soil and Rp 993.514.151 per m3/year for regosol soil. Water
credit of water retention unit were around Rp 14.16 per m3/year for
mediterranean soil, Rp 2.125 per m3/year for grumosol soil and Rp. 850 per
m3/year for regosol soil.
