Pranantya, Vanadani (2019) Penentuan Skala Prioritas Pengembangan Potensi Mata Air Untuk Irigasi di Kabupaten Tuban Dengan Menggunakan Metode Analytic Network Process. Sarjana thesis, Universitas Brawijaya.
Abstract
Potensi mata air di wilayah Kabupaten Tuban yang terdata di Dinas Pekerjaan Umum dan Penataan Ruang sejumlah 57 mata air. Mata air digunakan sebagai sumber air untuk irigasi oleh para petani. Mata air yang diteliti sejumlah 10 mata air. Penelitian ini dilakukan untuk mengetahui urutan skala prioritas pengembangan potensi mata air untuk irigasi. Urutan skala prioritas dihitung dengan menggunakan metode Analytic Network Process (ANP). Pemodelan ANP dilakukan dengan menggunakan bantuan paket program komputer Super Decision 2.10.0. Identifikasi potensi mata air dilakukan berdasarkan 3 aspek pengembangan sumber daya air yaitu aspek kuantitas air, aspek kualitas air, dan aspek kontinuitas aliran. Aspek kuantitas air diidentifikasi berdasarkan nilai debit air di tiap-tiap mata air. Aspek kualitas air diidentifikasi berdasarkan nilai daya hantar listrik pada suhu 25⁰C (DHL25⁰C) dan rasio serapan natrium (SAR). Aspek kontinuitas aliran diidentifikasi berdasarkan sifat aliran dari mata air. Hasil dari identifikasi potensi mata air digunakan sebagai data pemodelan ANP. Pemodelan ANP dilakukan dengan cara menentukan struktur alternatif, kriteria, dan sub kriteria dan pembobotan tiap alternatif, kriteria, dan sub kriteria. Bobot yang diberikan dalam rentang nilai 1 sampai dengan 9 digunakan untuk menghitung skala prioritas. Berdasarkan hasil penelitian ini dapat ditunjukkan kondisi mata air berdasarkan aspek kuantitas air, kualitas air, dan kontinuitas aliran. Aspek kuantitas air berada pada Kelas 2 (1.000 – 10.000 liter/detik) sampai Kelas 4 (100 – 1.000 liter/detik). Aspek kualitas air berada dalam kategori C2 – S1 (potensi bahaya salinitas sedang dan potensi bahaya alkalinitas rendah). Mata air di lokasi penelitian bersifat musiman. Urutan skala prioritas di lokasi penelitian meliputi Mata Air Bektiharjo, Mata Air Srunggo, Mata Air Ngerong, Mata Air Kerawak, Mata Air Beron, Mata Air Bangkok. Mata Air Jadi, Mata Air Mejiret, Mata Air Ngajaran, dan Mata Air Lanang.
English Abstract
Potential springs in the area of Tuban regency recorded in the Department of Public Works and Spatial Planning are 57 springs. Springs are used as a source of water for irrigation by farmers. The springs studied in 10 springs. The study was conducted to determine the order of priority scale development of potential springs for irrigation. The priority scale is calculated using Analytic Network Process method (ANP). ANP modeling is done using the help of a computer program package Super Decision 2.10.0. The identification of potential springs is based on 3 aspects of water resource development, namely aspects of water quantity, aspects of water quality, and aspects of flow continuity. The water quantity aspect is identified based on the water discharge value at each spring. Water quality aspects are identified based on the value of electrical conductivity at temperatures 25⁰C (DHL25⁰C) and sodium absorption ratio (SAR). Aspects of flow continuity are identified based on the nature of the flow from the spring. The results of the identification of potential springs are used as ANP modeling data. ANP modeling is done by determining alternative structures, criteria, and sub-criteria and weighting of each alternative, criteria, and sub-criteria. Weights given in the range of values from 1 to 9 are used to calculate priority scales. Based on the results of the study can be shown the condition of springs based on aspects of water quantity, water quality, and flow continuity. The water quantity aspect is in Class 2 (1000 – 10000 liters/second) to Class 4 (100 – 1000 liters/second). Water quality aspects are in the C2 – S1 category (potential danger of medium salinity and potential danger of low alkalinity). The springs at the study site are intermitten. The priority scale at the study sites included Bektiharjo Springs, Srunggo Springs, Ngerong Springs, Kerawak Springs, Beron Spring, Bangkok Springs, Jadi Springs, Mejiret Springs, Ngajaran Springs, and Lanang Springs.
