The Environmental Document Preparation and Land Acquisition and Resettlement Action Plan (LARAP) for Flood Control in Kali Langsur, Sukoharjo is a crucial initiative to mitigate the impact of recurrent flooding along the Langsur River, which flows through industrial and residential areas in Grogol and Sukoharjo Districts. This study was conducted as part of the readiness criteria for flood control infrastructure implementation.

The project focuses on hydrological and environmental studies, land acquisition assessments, and community engagement to ensure sustainable and socially responsible flood management solutions.

Key project components:

✔ Environmental impact assessment (EIA) and hydrological studies – Analyzing river sedimentation, flood patterns, and ecological conditions.

✔ LARAP implementation – Evaluating land acquisition, compensation schemes, and community resettlement strategies.

✔ Public consultation and stakeholder engagement – Ensuring local communities and affected parties are informed and involved in decision-making.

✔ Flood control design recommendations – Proposing river normalization, embankment strengthening, and water retention solutions.

✔ Regulatory compliance and permitting – Aligning the project with national environmental policies and obtaining necessary approvals.

This project plays a vital role in reducing flood risks, improving drainage efficiency, and ensuring climate resiliencein the region, ultimately enhancing the safety and well-being of local communities.

Status: 100% Completed – Ready for Implementation Phase

The Flood Forecasting and Warning System (FFWS) for BBWS Serayu Opak is an advanced initiative aimed at mitigating flood risks in the Serayu Bogowonto River Basin through the development of a real-time hydrological monitoring and early warning system. This project integrates hydrological, topographical, and environmental studies to design a data-driven flood prediction system that enhances disaster preparedness and response across multiple critical locations.

The system is designed to provide accurate, real-time flood predictions using a combination of automated river monitoring stations, telemetry sensors, and meteorological data analysis. These innovations enable authorities to anticipate flood events, issue timely warnings, and coordinate emergency responses effectively.

Key project components:

✔ Real-time flood forecasting system – Utilizing hydrological modeling and telemetry data from key monitoring stations.

✔ Installation of warning systems in flood-prone areas – Enabling early alerts for communities at risk.

✔ Hydrological and hydraulic analysis – Assessing rainfall patterns, river capacity, and flood dynamics in DAS Serayu, Tipar, and Ijo.

✔ Integration with regional emergency response systems – Ensuring coordinated actions between government agencies, disaster response units, and local communities.

✔ Community engagement and training programs – Strengthening local preparedness for flood events through workshops and simulations.

✔ Development of Standard Operating Procedures (SOPs) – Establishing protocols for emergency response, risk assessment, and flood mitigation measures.

✔ Data-driven decision support system – Providing predictive analytics to assist urban planning and infrastructure resilience efforts.

This project is a vital step in improving climate resilience and disaster management, ensuring that local authorities, residents, and businesses receive timely and accurate flood warnings to minimize damage and loss. By implementing advanced forecasting models and smart flood monitoring technologies, this initiative supports sustainable water resource management and long-term flood mitigation strategies in the region.

Status: 100% Completed – Ready for Implementation Phase

Effective operation and maintenance (O&M) of raw water infrastructure are crucial for ensuring sustainable water resource management. This project focuses on updating the O&M manual for raw water facilities across 12 key locations in Riau Islands Watershed (WS Kepulauan Riau). The initiative, conducted by Balai Wilayah Sungai Sumatera IV in collaboration with PT. Globetek Glory Konsultan KSO CV. Gumbel Engineering Consultant, aims to establish a standardized and data-driven operational framework to improve efficiency, longevity, and service quality.

The project includes hydrological analysis, infrastructure condition assessments, and technical operation planning, ensuring each facility meets regulatory standards such as Law No. 17 of 2019 on Water Resources. The manual outlines operational procedures, maintenance schedules, and emergency response strategies for reservoirs, intake structures, and distribution systems in Batam, Bintan, Karimun, Lingga, and Natuna.

By implementing a comprehensive O&M strategy, this project enhances system reliability, reduces operational risks, and ensures optimal water supply for communities and industries. The finalized manual serves as a critical guideline for long-term water infrastructure sustainability in the Riau Islands.

🔹 Status: 100% Completed – Ready for Implementation

The Gongseng Dam was constructed to enhance water resource management, support irrigation services, and strengthen food security in Bojonegoro Regency. Additionally, the dam plays a vital role in providing raw water for the surrounding community, while also contributing to flood mitigation and renewable energy potential. With the completion of its physical construction, an Operation & Maintenance (OP) Certification is required to ensure the dam can be fully operational and utilized efficiently.

The Gongseng Dam features a rock-fill structure with a vertical core, designed for long-term stability. It provides essential functions such as supplying irrigation water for 6,191 hectares of farmland, reducing flood risks by 176.44 m³/sec, generating microhydro power with a potential of 0.70 MW, and delivering 300 liters per second of raw water for domestic and industrial needs.

From a geological perspective, the dam is built on marl rock formations, requiring careful structural evaluation to ensure long-term stability and groundwater infiltration control. Given the potential for seismic activity, foundation reinforcement using grouting techniques is necessary to maintain structural integrity and prevent water seepage along fault zones.

Efficient operation of the Gongseng Dam depends on well-maintained hydromechanical equipment, which facilitates water discharge, regulation, and overall system performance. This includes gates, valves, and spillway control mechanisms, all of which require routine inspections and preventive maintenance to ensure optimal functionality. By integrating modern engineering solutions, proactive maintenance strategies, and regulatory compliance, the Gongseng Dam is positioned as a key water infrastructure asset, supporting regional development, water conservation, and disaster mitigation efforts.

📍 Key Specifications:

• Dam Type: Rock Fill with Vertical Core
• Main Dam Height: 34.00 m | Saddle Dam Height: 12.00 m
• Total Peak Length: 422.00 m
• Reservoir Capacity: 22.43 million m³ (Effective: 14.75 million m³, Dead Storage: 7.68 million m³)
• Inundation Area: 390.65 Ha | Water Catchment Area: 51.21 km²

Status: 100% Completed – OP Certification in Progress
