Abstract

A decline in irrigation system performance is generally caused by infrastructure degradation and suboptimal management, which affect the effectiveness of water distribution to agricultural land. This study aims to evaluate the physical and functional performance of the irrigation network in the Gesang Irrigation District in Malang Regency as a basis for determining appropriate maintenance strategies. The research method employed a field survey approach and an irrigation performance index assessment based on parameters including physical infrastructure, crop productivity, supporting facilities, personnel organization, documentation, and the institutional framework of water-user farmers. The assessment was conducted on 33 sections of primary canals through observation of structural conditions and calculation of performance weights. The results of the study indicate that the physical condition of the infrastructure exhibits varying degrees of damage, with the following proportions: Good at 33.33%, Slightly Damaged at 33.33%, Moderately Damaged at 21.21%, Severely Damaged at 9.09%, and Natural at 3.03%. The overall performance score for the physical infrastructure reached 73.16%, which falls into the Moderately Damaged category. The component with the lowest score was the control structures at 67.50%, due to malfunctions in the distribution gates and intake structures. These conditions indicate that water distribution functions are beginning to be disrupted, necessitating rehabilitation at points of severe damage as well as intensive preventive maintenance to ensure the sustainability of irrigation services.

Abstract

The agricultural sector relies heavily on the reliability of irrigation infrastructure to ensure food production stability. This study aims to evaluate the physical performance of irrigation infrastructure in the Santren Irrigation District (DI), located in Jatisari Village, Tajinan Subdistrict, Malang Regency. The Santren IR serves 50 hectares of agricultural land supported by a network of primary canals spanning 2,488.45 meters, secondary canals 198.71 meters, and tertiary canals 167.87 meters. The research method employed was quantitative descriptive, involving an inventory of damage through field surveys and visual inspections of structures and canals. Performance assessment was based on the Irrigation System Performance Index (IKSI) criteria in accordance with Ministry of Public Works and Public Housing Regulation No. 12/PRT/M/2015, which covers the physical condition of main structures, conveyance channels, control structures, and other supporting facilities. The research results indicate that the physical infrastructure at the Santren Irrigation District is generally in adequate condition. Based on calculations, the total Irrigation System Performance Index (IKSI) score was 85.29%. This score places the performance of the Santren Irrigation District’s irrigation system in the “Still Functioning Well” category. However, several technical issues were identified in the field, such as minor cracks in the concrete wall structures, corrosion on the water gates, and sediment accumulation in the sediment traps and outflow channels, which have the potential to hinder the smooth distribution of water. Based on these findings, it is recommended that the managing authority (the Public Works and Water Resources Agency of Malang Regency) implement more systematic routine maintenance, particularly sediment dredging in sediment traps and functional repairs to corroded floodgate components. In addition, improvements to the quality of inspection roads are necessary to ensure unimpeded operational access and the sustainable monitoring of the irrigation network.
