This project aims to reassess the design of the Akelamo Weir and Irrigation Network to ensure its capacity and efficiency in supporting food security and increasing farmers’ income in East Halmahera Regency, North Maluku Province. The Akelamo Irrigation Area covers 3,600 hectares of farmland, with its main water source from the Akelamo River, divided into D.I. Akelamo Kiri (800 Ha) and D.I. Akelamo Kanan (2,800 Ha).

The project is conducted by PT. Globetek Glory Konsultan under the direction of Balai Wilayah Sungai Maluku Utara, with a duration of 210 calendar days. A design review is necessary due to changes in paddy field areas, rising material costs, and the discovery of porous soil in the irrigation network, which may cause leakage. Additionally, changes in the catchment area could affect the weir’s dependable discharge, requiring further analysis.

The scope of the review includes technical investigations, hydrological surveys, sedimentation analysis, and geotechnical and soil mechanics evaluations. Furthermore, a redesign is conducted to optimize channel capacity, improve water distribution structures, and ensure the effective functioning of sediment flushing systems. With an approach based on national standards, this project is expected to enhance irrigation system efficiency, strengthen weir infrastructure, and support sustainable agriculture in East Halmahera.
