The Kali Jajar Rubber Dam Project is a Detail Engineering Design (DED) initiative aimed at developing sustainable water management infrastructure in Pekalongan City, Central Java. The project responds to the region’s growing need for reliable raw water sources, flood control, and improved irrigation efficiency.
The consultant team prepared a comprehensive design package that includes:
Hydrological and hydraulic analysis for water flow management.
Geotechnical investigations to ensure structural stability and safety.
Structural and architectural design of the rubber dam and its supporting facilities.
Environmental and social considerations to minimize impacts and enhance community benefits.
Cost estimation and work planning for effective implementation.
Throughout the study, multidisciplinary experts collaborated to produce a design that balances technical feasibility, economic efficiency, and environmental sustainability. The rubber dam is expected to improve water supply reliability, reduce flood risks, and support agricultural productivity in Pekalongan.
This project represents a crucial step in strengthening regional infrastructure by delivering a comprehensive, forward-looking design solution that will serve as the foundation for future construction works.
The Semarang Barat Raw Water Supply Improvement Project is a strategic infrastructure initiative aimed at strengthening the reliability of water resources for the region. The supervision services were carried out by a dedicated team of professional engineers and technical experts, ensuring that every stage of the project adhered to the highest standards of quality, safety, and environmental compliance.
The scope of work includes:
Pipeline Transmission System – covering procurement, installation, pressure testing, and supporting structures such as thrust blocks and accessories.
Inspection Roads and Bridges – to ensure accessibility and long-term operational reliability.
Drainage Structures – including cross-drain systems to enhance water flow management.
Field Supervision and Design Review – aligning technical designs with on-site conditions and conducting adjustments when necessary.
Quality and Safety Monitoring – enforcing strict compliance with construction safety regulations and technical specifications.
Progress Evaluation and Reporting – documenting activities, challenges, and solutions in monthly reports.
During the first reporting period (February – March 2024), key achievements included:
Mobilization of personnel, equipment, and supporting facilities.
Execution of topographic surveys and initial soil investigations.
Review and verification of construction drawings.
Coordination meetings and design review discussions with stakeholders.
Preparation of preliminary and monthly supervision reports.
The consultant team was structured into specialized roles including Team Leader, Supervision Engineer, Quality Engineer, Quantity Engineer, HSE Engineer, and supporting staff, ensuring well-coordinated supervision across all technical aspects.
Through this project, the supervisory consultant plays a critical role not only in monitoring construction progress but also in providing proactive solutions to challenges in the field. The work is expected to deliver a reliable and sustainable raw water supply system, supporting both the community and long-term regional development.
