ESTIMASI NILAI EKONOMI AIR ERSIH BAGI PERUSAHAAN DAERAH AIR MINUM UNTUK INISIASI KONSEP PEMBAYARAN JASA LINGKUNGAN DI KOTA PALOPO
Abstract
Latuppa stream, the most potential water supply to PDAM Palopo and irrigation to agricultural land, hasserious environmental degradation due to behavioural factors of local inhabitants in watershed area of Latuppa whocontinuously exploit forest area to produce woods, housing, and plantation. Those contribute to flood and landslide inrainy season and extreme dryness in dry season in Palopo. PDAM in municipality of Palopo encounters the mostsignificant impact to fluctuation of water debit in Latuppa stream that influences on the process of water production anddistribution. Therefore, protection of water management in Latuppa watershed uses Payment for Environmental Service(PES) to minimize destructive effect of water catchment area and to fulfill pure water supply of PDAM. Based on likertscale of mean score, to obtain data related to perception and people behavior in the headwaters area to rehabilitate watercatchment area , it is found that score 4,00 refers to the will of people in watershed area to rehabilitate water catchmentarea. Estimation of economical value of water supply to PDAM using residual imputation approach shows that obtainedscore of water rate is 4.230.898.496 after minus 28% of income tax. Economical contribution of its water supply isobjective consideration to decide the cost spent by PDAM to rejuvenate forest in headwaters area since it influences onwater production capacity of PDAM Palopo.References
