Abstract

Desa Labanasem Kecamatan Kabat Kabupaten Banyuwangi mempunyai permasalahan infrastruktur drainase yang kurang layak untuk mengalirkan air ke sawah serta kondisi pada saat musim hujan mengalami genangan air tinggi akibat tidak adanya saluran pembuangan air. Tujuan dari kegiatan ini untuk menerapkan U-Ditch Precast dan Buis Beton untuk mengatasi permasalahan infrastruktur drainase. Kegiatan meliputi survei dan observasi lokasi, melakukan dialog dan kerja sama dengan kelompok tani, melaksanakan pemasangan saluran U-Ditch Precast dan Buis Beton yang dilakukan secara swadaya masyarakat dan kelompok tani. Solusi yang efisien dilakukan dengan penerapan pemasangan U-Ditch Precast sepanjang 15 m dengan kebutuhan 25 unit untuk mengatasi genangan air tinggi saat musim hujan karena tidak adanya saluran air dan Buis Beton sepanjang 15 m dengan kebutuhan 15 unit untuk mengatasi saluran irigasi sawah yang tidak layak.

Abstract

The Badeng River in Banyuwangi, Indonesia, has experienced rapid sediment re-accumulation after the 2022 normalization works. This study evaluates post-normalization sedimentation using a one-dimensional HEC-RAS sediment transport model supported by field surveys, sediment sampling, river geometry data, and dredging records. The model predicted annual sediment accumulation of 4,494.88 m³/year at Pakel and 4,380.02 m³/year at Garit. Comparison with dredging records produced a mean absolute error of 1,271.27 m³, corresponding to a deviation of approximately 38–42%. This deviation reflects combined uncertainty from DEM-derived channel geometry, localized excavation records, and excavator-bucket-based dredging volume estimation. Despite this uncertainty, the simulated deposition pattern was consistent with field observations and confirmed substantial sediment recovery within three years after normalization. The results indicate that 1D HEC-RAS is suitable as a decision-support tool for identifying sedimentation-prone reaches, planning dredging intervals, and supporting sediment management in data-limited tropical rivers.
