The Flood Alert Level Review for Cirarab River was conducted to assess the causes of severe flooding in Tangerang and to formulate effective mitigation strategies. The study identified key issues, including obstructed river flow due to bridge structures, inadequate embankment elevation in Gelam Jaya Village, and sedimentation and narrowing near Akong Factory in Sepatan District. These factors significantly contributed to prolonged flooding, necessitating urgent river normalization and infrastructure improvements. The study also revealed that six out of sixteen drainage gatesalong the Cirarab River embankment were non-functional, limiting the flood drainage capacity, especially in Villa Permata Tangerang. Additionally, the Sarakan Dam, located on the border of Gitung Village and Kosambi Village, remained structurally intact but had three damaged floodgates that were temporarily replaced with wooden partitions.

The evaluation covered existing water resource infrastructure, including water level monitoring posts, water pumps, drainage gates, and embankments. It was found that only one out of three water monitoring posts was integrated with an online early warning system managed by Tangerang BPBD, while the others functioned as manual Water Guessing Posts (PDA) at the Ledug River Estuary and Situ Bulakan Estuary. The study also recorded nine operational water pumps, strategically placed for lake discharge, drainage, and river estuaries. Most embankments along Gelam Jaya Village in Pasar Kemis District were in good condition, but some sections showed visible cracks requiring maintenance.

To enhance flood preparedness, flood discharge calculations were performed using three different methods: the HSS method, HEC-HMS software modeling, and AWLR data analysis. The insights gained from this study provide a comprehensive foundation for flood risk reduction, infrastructure improvement, and sustainable urban resilience planning in the Cirarab River basin.

The agricultural sector remains a top priority for national development, with stable food security being a key objective of the current government program. However, challenges such as land conversion for plantations, increased rice demand, and the influx of imported rice pose significant threats to domestic agricultural sustainability. Based on the North Halmahera WS PSDA Pattern (2020), several potential irrigation areas have been identified for development, yet they are not included in Ministerial Regulation No. 14 of 2015. To support the expansion of irrigation infrastructure, the 2023 Budget Year has allocated resources for the Planning Review of DI. Soamaetek (223 Ha), DI. Kusuri (178 Ha), and DI. Paca-Leleoto (159 Ha). These areas, located in North Halmahera Regency, possess excellent soil conditions, favorable topography, and abundant water resources, making them highly suitable for irrigation enhancement.

In the supplementary irrigation channel, an existing water gate is used to regulate water flow for rice fields in Leleoto Village. However, local farmers have reported that during heavy rainfall, the channel cannot accommodate excess water, causing overflow into the rice fields. Additionally, the small size of the water gate restricts water flow, leading to inefficiencies in irrigation and flood mitigation. Farmers have requested the removal and enlargement of the water gate to ensure smoother water distribution. Since the asset belongs to the Agriculture Service of North Halmahera Regency, any modifications require official coordination. As a solution, it is recommended that the existing water gate be replaced with a larger structure, designed to improve water regulation, prevent flooding, and enhance agricultural productivity.

Status: Ongoing – Planning & Coordination Phase
