Penilaian dan Evaluasi Kinerja Daerah Irigasi Parung di Kecamatan Janapria Kabupaten Lombok Tengah

Abstract

Abstract: Irrigation networks are essential infrastructure for supplying and distributing water to support agricultural activities; therefore, their physical condition must be maintained through continuous operation and maintenance. The Parung Irrigation Scheme (DI Parung) in Janapria District, Central Lombok Regency, plays a strategic role in supporting agricultural productivity. However, several infrastructure components have experienced deterioration due to the age of the structures, sedimentation, channel damage, and suboptimal maintenance activities. Therefore, an assessment and evaluation of the physical infrastructure performance are required as a basis for determining operation and maintenance priorities for the irrigation network. This study aims to assess and evaluate the performance of the physical infrastructure of the Parung Irrigation Scheme based on the Regulation of the Minister of Public Works and Housing No. 12/PRT/M/2015. The study employed a descriptive method with a field survey approach. Data were collected through field observations, documentation, and secondary data obtained from relevant institutions. The assessment focused on the main structures, conveyance channels, structures along the conveyance channels, drainage channels and associated structures, inspection roads, as well as offices, staff housing, and storage facilities. The results indicate that the physical infrastructure of the Parung Irrigation Scheme generally remains capable of supporting irrigation water delivery effectively, although several defects were identified in the channels and ancillary structures that may reduce water distribution efficiency. Therefore, routine maintenance, rehabilitation of damaged components, and improved coordination between the managing institutions and the Water User Farmers Association (P3A) are required to maintain the optimal, effective, and sustainable performance of the irrigation network.

Abstrak: Jaringan irigasi merupakan prasarana penting yang berfungsi menyediakan dan mendistribusikan air untuk menunjang kegiatan pertanian sehingga kondisi fisiknya harus dipertahankan melalui operasi dan pemeliharaan secara berkelanjutan. Daerah Irigasi (DI) Parung di Kecamatan Janapria, Kabupaten Lombok Tengah memiliki peranan strategis dalam mendukung produktivitas pertanian, namun beberapa komponen prasarana mengalami penurunan kondisi akibat usia bangunan, sedimentasi, kerusakan saluran, dan kurang optimalnya kegiatan pemeliharaan. Oleh karena itu, diperlukan penilaian dan evaluasi kinerja prasarana fisik sebagai dasar dalam menentukan prioritas operasi dan pemeliharaan jaringan irigasi. Penelitian ini bertujuan untuk menilai dan mengevaluasi kinerja prasarana fisik jaringan irigasi DI Parung berdasarkan Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat Nomor 12/PRT/M/2015. Metode yang digunakan adalah deskriptif dengan pendekatan survei lapangan. Data dikumpulkan melalui observasi, dokumentasi, dan data sekunder dari instansi terkait. Penilaian difokuskan pada komponen bangunan utama, saluran pembawa, bangunan pada saluran pembawa, saluran pembuang beserta bangunannya, jalan inspeksi, serta kantor, perumahan, dan gudang. Hasil penelitian menunjukkan bahwa kondisi prasarana fisik jaringan irigasi DI Parung secara umum masih mampu mendukung pelayanan air irigasi dengan baik, meskipun masih ditemukan beberapa kerusakan pada saluran dan bangunan pelengkap yang berpotensi menurunkan efisiensi distribusi air. Oleh karena itu, diperlukan pemeliharaan rutin, rehabilitasi pada bagian yang mengalami kerusakan, serta peningkatan koordinasi antara instansi pengelola dan Perkumpulan Petani Pemakai Air (P3A) agar kinerja jaringan irigasi tetap optimal, efektif, dan berkelanjutan.
