Daerah Irigasi (D.I.) Krueng Jreu merupakan daerah irigasi kewenangan pemerintah pusat yang melayani areal seluas 4.547 hektar dan memiliki 246 aset strategis yang terdiri atas 12 jenis aset. Seiring bertambahnya umur infrastruktur dan meningkatnya kebutuhan pemeliharaan, penerapan manajemen aset diperlukan untuk mengetahui kondisi dan fungsi aset serta menentukan prioritas perbaikan secara objektif. Penelitian ini bertujuan melakukan inventarisasi aset jaringan irigasi, menilai kondisi dan fungsi aset, menentukan prioritas perbaikan aset, serta menganalisis perbedaan prioritas perbaikan antar jenis aset menggunakan uji Kruskal–Wallis.
Data penelitian diperoleh melalui observasi lapangan, dokumentasi, dan formulir survei berdasarkan Peraturan Menteri Pekerjaan Umum dan Perumahan Rakyat Republik Indonesia Nomor 12/PRT/M/2015. Jumlah sampel ditentukan menggunakan rumus Slovin dengan target minimal 72 aset dan berhasil dinilai sebanyak 73 aset yang mewakili 12 jenis aset. Penilaian kondisi (Ki) dan fungsi (Fi) dilakukan untuk memperoleh nilai prioritas perbaikan (Pi) berdasarkan kondisi, fungsi, dan luas areal layanan aset. Nilai Pi kemudian digunakan untuk menyusun urutan prioritas perbaikan, sedangkan perbedaan prioritas perbaikan antar jenis aset dianalisis menggunakan uji Kruskal–Wallis terhadap 62 aset dari enam kelompok jenis aset yang memenuhi syarat ukuran sampel minimum.
Kondisi aset jaringan irigasi di Daerah Irigasi Krueng Jreu secara umum tergolong baik. Penilaian kondisi menghasilkan 42 aset (57,5%) berkategori baik, 24 aset (32,9%) rusak ringan, 6 aset (8,2%) rusak sedang, dan 1 aset (1,4%) rusak berat. Penilaian fungsi menghasilkan 39 aset (53,4%) berkategori baik, 28 aset (38,4%) kurang berfungsi, 4 aset (5,5%) berkategori buruk, dan 2 aset (2,7%) tidak berfungsi. Nilai prioritas perbaikan (Pi) terendah diperoleh pengukur debit SPL 2–3 sebesar 2,40, diikuti pengukur debit BJKi 1c sebesar 3,50 dan bangunan inlet BI 2i sebesar 3,65 sehingga ketiga aset tersebut menjadi prioritas utama untuk diperbaiki. Bendungan BKL 0 memiliki nilai Pi sebesar 499,96 sehingga menjadi aset dengan prioritas perbaikan terendah. Uji Kruskal–Wallis memberikan nilai signifikansi 0,003 (p < 0,05), yang menunjukkan adanya perbedaan prioritas perbaikan antar jenis aset di Daerah Irigasi Krueng Jreu. Hasil penelitian ini dapat digunakan sebagai dasar dalam manajemen aset untuk menentukan urutan prioritas pemeliharaan dan rehabilitasi sehingga pengelolaan aset lebih terarah dan kinerja jaringan irigasi tetap terjaga.

Krueng Jreu Irrigation Area (D.I. Krueng Jreu) is an irrigation scheme under the authority of the central government, serving an irrigated area of 4,547 hectares and consisting of 246 strategic assets classified into 12 asset types. As the infrastructure ages and maintenance demands increase, the implementation of asset management is essential to assess the condition and functionality of irrigation assets and to determine maintenance priorities objectively. This study aimed to inventory irrigation network assets, evaluate their condition and functionality, determine asset repair priorities, and analyze differences in repair priorities among asset types using the Kruskal–Wallis test. The research data were collected through field observations, documentation, and survey forms based on the Regulation of the Minister of Public Works and Public Housing of the Republic of Indonesia Number 12/PRT/M/2015. The sample size was determined using Slovin’s formula, with a minimum target of 72 assets, and a total of 73 assets representing all 12 asset types were successfully assessed. Asset condition (Ki) and functionality (Fi) were evaluated to obtain the repair priority index (Pi), which was calculated based on asset condition, functionality, and service area coverage. The Pi values were then used to establish the repair priority ranking, while differences in repair priorities among asset types were analyzed using the Kruskal–Wallis test on 62 assets from six asset-type groups that met the minimum sample size requirement. Overall, the condition of the irrigation network assets in the Krueng Jreu Irrigation Area was classified as good. The condition assessment indicated that 42 assets (57.5%) were in good condition, 24 assets (32.9%) were slightly damaged, 6 assets (8.2%) were moderately damaged, and 1 asset (1.4%) was severely damaged. The functionality assessment showed that 39 assets (53.4%) were functioning well, 28 assets (38.4%) were functioning inadequately, 4 assets (5.5%) were in poor condition, and 2 assets (2.7%) were non-functional. The lowest repair priority index (Pi) was obtained by the SPL 2–3 flow measurement structure (2.40), followed by the BJKi 1c flow measurement structure (3.50) and the BI 2i inlet structure (3.65), making these three assets the highest priorities for repair. In contrast, the BKL 0 weir had the highest Pi value (499.96), indicating the lowest repair priority. The Kruskal–Wallis test produced a significance value of 0.003 (p < 0.05), indicating a significant difference in repair priorities among asset types in the Krueng Jreu Irrigation Area. The findings of this study can serve as a basis for asset management in establishing maintenance and rehabilitation priorities, thereby supporting more effective asset management and sustaining the performance of the irrigation network.
