The implementation of operations and maintenance on rivers, including their facilities/infrastructure, plays an important role in the life cycle of River Basin infrastructure. In the process, a River infrastructure needs to be assessed for performance in order to carry out improvements/maintenance and refinement of the operational process on an ongoing basis in order to obtain optimal river infrastructure performance. Performance assessment is a process of identifying problems, analyzing, and evaluating which is carried out independently, objectively and professionally based on observations in the field to assess the reliability of the performance of an infrastructure system. In this case, an assessment is carried out on existing river facilities/infrastructure and comparing them with standard performance indicators. By carrying out performance assessment activities, we can obtain real data on river infrastructure in the field and its problems. The Real Operation and Maintenance Needs Figure (AKNOP) provides justification and estimation of the operation and maintenance activities to be carried out including the cost components. AKNOP is a reference for the implementation of operation and maintenance activities of river infrastructure. The diversity of infrastructure, scope of OP activities and differences in unit prices in each region are separate problems in the preparation of AKNOP. Formulation of problems and application of solutions to problems in the field are part of the process of increasing river utilization as well as utilization of water resources. In relation to the above, the Ministry of Public Works and Public Housing through the Sulawesi I River Region Office, Sulawesi I SDA Operation and Maintenance Work Unit, considers it necessary to have activities to Prepare Performance Assessments and River AKNOP in Manado City, Minahasa Regency, North Minahasa Regency with the hope that in the process of operation and maintenance of river facilities and infrastructure function optimally and sustainably
Based on the conclusions obtained from the work of the River Performance Assessment and AKNOP Compilation Work in Manado City, Minahasa Regency, and North Minahasa Regency, several things that can be immediately followed up as recommendations for this work are as follows:
- It is necessary to immediately form a river management institution in Manado City, Minahasa Regency, and North Minahasa Regency which is fully responsible for the Operation and Maintenance (OP) activities of rivers in Manado City, Minahasa Regency, and North Minahasa Regency.
- Maintenance activities for river facilities and infrastructure in Manado City, Minahasa Regency, and North Minahasa Regency can be immediately followed up with Detailed Rehabilitation Design activities, both independently and contractually
