Abstract

Daerah Irigasi (DI) Blimbing mengairi lahan pertanian sebesar 319 Ha. Kondisi fisikjaringan irigasi banyak mengalami kerusakan yang mengakibatkan menurunnya fungsijaringan irigasi. Sehingga diperlukan pemeliharaan untuk mengembalikan fungsi jaringanirigasi ke kondisi semula. Tujuan dari penelitian ini adalah untuk memperoleh strategipemeliharaan jaringan irigasi DI Blimbing yang optimal, dengan memperhatikan biaya.Tahap awal adalah mengidentifikasi, menilai kondisi fisik dan fungsi bangunan irigasi danmembuat urutan prioritas pemeliharaan jaringan irigasi. Kemudian menghitung Benefitand Cost untuk menilai kelayakan. Penelitian ini menggunakan Metode Linier Programmingyang terdiri dari fungsi tujuan dan kendala. Sebagai fungsi tujuan adalahmemaksimumkan nilai prioritas/nilai manfaat, sedangkan untuk fungsi kendala yaituketerbatasan biaya. Mengacu biaya sebesar Rp. 100.000.000, permodelan/optimasipemeliharaan yang dikaitkan untuk memaksimalkan nilai prioritas atau nilai manfaatdiperoleh ruas yang dapat diperbaiki sebanyak 7 ruas dengan anggaran sebesar Rp.99.998.877. Hasil optimasi dengan memaksimalkan nilai prioritas sama dengan hasiloptimasi dengan memaksimalkan nilai manfaat.

Abstract

Ampal Catchment Area has 25.273 km2 area and 4.699 km main river length, which planned to have 13 flood control construction. Until 2017, this catchment area has only three flood control construction. The watershed has only three built-in batters that are used to reduce the amount of flood discharge flowing on the Ampal river. Based on these conditions, it is necessary to analyze the magnitude of the difference of flood peak discharge on the existing condition (three bendali) compared with the condition of the plan (thirteen bendali). Therefore, analyzed the function and influence of flood control construction in Ampal Catchment Area by counting the flood peak discharge in each condition. From the analysis result, obtained the amount of peak discharge flowing in Ampal river existing condition is equal to 170,40 m3/s while at the condition of plan is equal to 83,80 m3/s. From the results of analysis, it is stated that the magnitude of the decrease of debit (?Q) after all the builds is 86.60 m3/s.
