Abstract

The objective of this study was to determine the order of priority for the development of potential springs as a source of irrigation water using the Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) method. This research was conducted in 11 locations of springs in Singosari District, Malang Regency. The spring potential assessment was carried out using 4 criteria consisting of water quantity, water quality, flow continuity, and irrigation area. The quantity of water at the research site is in the range of 8 liters/second – 45,180 liters/second. The water quality of the 11 springs is in the same class, namely C2-S1 with medium salinity hazards and low alkalinity hazards. There were 7 springs with annual flow and 4 springs with seasonal flow. The irrigated area in the study area ranged from 0.12 ha to 98 ha. The order of priority for the 3 highest springs to be developed based on the minimum discharge, namely Umbulan Spring, Sekaran Spring, and Pakisuceng Spring, while based on the maximum discharge, namely Umbulan Spring, Suko Spring, and Petung Wulung Spring.

Abstract

Mata air karst merupakan salah satu potensi sumber daya air di wilayah Kabupaten Tuban yang memiliki peranan penting sebagai pemasok kebutuhan air irigasi pada lahan pertanian. Tujuan penelitian ini adalah untuk mengkarakterisasi secara hidrokimia air dari mata air karst yang digunakan sebagai sumber air irigasi. Karaktrisasi hidrokimia yang dilakukan mencakup substansi identifikasi tipe kimia air dan penilaian kelayakan kualitasnya sebagai sumber air irigasi. Tipe kimia air ditentukan dengan menggunakan diagram trilinier Piper. Kelayakan kualitas air untuk irigasi dinilai berdasarkan potensi bahaya salinitas dan potensi bahaya alkalinitasnya. Berdasarkan hasil penelitian dapat ditunjukkan bahwa karakteristik hidrokimia air dari mata air karst di lokasi penelitian adalah memiliki tipe kimia Ca2+-Mg2+–HCO3–, potensi bahaya salinitas sedang, dan potensi bahaya alkalinitas rendah. Seluruh air dari mata air karst di lokasi penelitian merupakan air dengan kualitas yang baik untuk irigasi.

Abstract

The utilization of groundwater potential for irrigation has consequence for the high operational and maintenance costs of groundwater irrigation systems. One solution to these problems is the selection of high economic value crop types cultivated in groundwater irrigation lands. This study aims to determinate the alternative of types of agricultural crops that can be cultivated on groundwater irrigation land based on the quality of groundwater used as irrigation water based on the procedure: determination of groundwater quality index for irrigation, determination of types of agricultural crops based on criteria for tolerance to salt, adjustment of types of crop that have been determined with the criteria of high economic value crops, and adjustment to the types of crops that have been commonly cultivated by farmers in the local area. This procedure can be used as a solution to the absence of guidelines that can be used to determine alternative of types of agricultural plants on groundwater irrigation land. The results of this research showed the potential of ground water used as a source of irrigation water in the study site was dominated by groundwater with an index value of 70-85, where agricultural crops that could be recommended for planting were tolerant crops, moderately tolerant crops, and moderately sensitive crops to salt. The index value of groundwater quality for irrigation was mapped so obtained that zoning model of groundwater quality for irrigation and its suitability for the type of agricultural crops that can be cultivated.
