Farriansyah, Anang M. (2019) Model Ekualisasi Alokasi Air Untuk Sistem Sungai Dan Multiwaduk. Doctor thesis, Universitas Brawijaya.
Abstract
Surplus dan defisit neraca air di tiap simpul bangunan utama pengambilan air di sistem sungai membutuhkan optimasi alokasi air, agar porsi alokasi air (K) sebagai rasio pemberian air dan kebutuhan air dapat setara. Jika tidak direncanakan, maka alokasi air akan mengancam keberlanjutan operasional dan tujuan bersama. Karena Indonesia memandang air sebagai barang publik, maka digagas “Model Ekualisasi Alokasi Air” (MEQAA) agar tercapai K yang sama antar pengguna sejenis (irigasi). Pembangunan model diinspirasi dari ketidaksetaraan K antar daerah irigasi di wilayah sungai Lombok. Model menggunakan pemrograman berbasis Ms. Excel yang dibentuk dari pendekatan sistem, persamaan keseimbangan massa, dan fungsi optimasi, dengan kriteria keberlanjutan-efisiensi-keadilan. Berdasarkan uji coba dengan berbagai skenario skema sungai yang independen sampai dependen berikut data ketersediaan air dan kebutuhan air yang tunggal sampai seri, bahwa MEQAA dapat: i) melahirkan model spesifik untuk perhitungan alokasi air, ii) menyelaraskan kinerja multiwaduk sehingga berkelanjutan, iii) menghasilkan K setara namun kontras dengan operasional yang belum terkendali, iv) menghasilkan K setara namun tidak berbeda dengan eksekusi operasional yang terkendali, dan v) menghasilkan K lebih unggul di simpul yang terintervensi. MEQAA perlu dikembangkan untuk memodelkan sistem sungai interdependen, sekaligus meningkatkan fasilitas antarmuka. Untuk meminimumkan deviasi keluaran MEQAA dengan eksekusi operasional perlu memperhatikan faktor hirdologi, hidrolika bangunan air dan kemampuan operator lapangan.
English Abstract
Water surplus and deficit in every intake node in river systems require equalization of water allocation with water allocation portion indicator (K) as water realease and demand ratio. If it is not planned, then water allocation will threaten operational sustainability and common goal. Since Indonesia views water as public goods, it is initiated to create “Water Allocation Equalization Model” (MEQAA) so that K-equal between the same user (irrigation) is obtained. The model development was inspired by the inequality of K inter irrigation area in Lombok river basin. The model uses Ms. Excel-based program which is formed by system approach, water balance equations, and optimization functions, with sustainability-efficiency-equity criteria. Based on the trial with various independent and dependent river scheme scenarios including single and serial data of water availability and water demand, it is obtained that MEQAA can: i) produce specific model for water allocation calculation, ii) harmonize the performance of multi-reservoir storage and release, iii) produce output with K-equal that contrast with uncontrolled operation, iv) produce output with K-equal but not different with controlled operational execution, and v) produce output with equal and unequal K due to the application of intervention policy of water allocation operation in specific node. MEQAA needs to be developed to model interdependent river system and also to improve interface facilities. In order to minimize deviation of MEQAA output with operational execution, it is necessary to consider the external factors, such as hydrology, hydraulics structure, and the ability of field operators
