Abstract

El Nino and La Nina in Indonesia are one of the reasons that caused climate changes, which has possibility of drought and flood disasters. Sragen Regency wherethe dry season occurs, drought happened meanwhile other areas experience floods and landslides. A study on drought needs to be carried out so as to reduce the risk of losses due to the drought hazard. This study is to determine the drought index in Sragen Regency based on several methods and the correlation of each methods and its suitability to the Southern Oscillation Index (SOI) and rainfall. Drought was analyzed using several methods such as Palmer Drought Severity Index (PDSI), Thornthwaite-Matter, and Standardized Precipitation Index (SPI) then correlated with SOI to determine the most suitable method for SOI. The variables are applied in this method are rainfall, temperature, and evapotranspiration. The results showed that the drought potential of the Palmer method is only in Near Normal conditions, which is 1%, Severe drought conditions are 29% for the Thornthwaite-Matter method, and Extreme Dry conditions only reach 1,11% for the SPI method. The PDSI and SPI methods are inversely proportional to the Thornthwaite-Matter method and the most suitable method for SOI values or rainfall is the SPI method. These three methods can be identified the potential for drought with only a few variables so that they could be applied if they only have those data.Keywords: Drought, PDSI, Thornthwaite-Matter, SPI, SOI

Abstract

Berdasarkan PP No. 16 Th. 2006, pembangunan tata air menjadi tanggung jawab pemerintah daerah oleh BUMD. Pelayanan PDAM Depok tahun 2017 sebesar 16,38% dan target tahun 2021 sebesar 30,10%. Tujuan dari penelitian ini adalah untuk mengkaji potensi ketersediaan air bersih Kota Depok tahun 2021 berdasarkan strategi RPJMD Kota Depok 2016-2021 untuk mencapai target PDAM Depok. Metode yang digunakan dalam penelitian ini adalah dengan melakukan proyeksi jumlah penduduk, proyeksi kebutuhan air serta analisis potensi ketersediaan air berdasarkan RPJMD Kota Depok 2016-2021. Hasil analisis, potensi ketersediaan air Kota Depok tahun 2021 berdasarkan RPJMD Kota Depok 2016-2021 masih di bawah target PDAM Depok sebesar 28,80%.
