- Abstract
Operation and maintenance of a dam that does not follow established procedures will not only reduce the effectiveness of the dam in question. However, they can also endanger the safety of the dam. The fact that the risk of a dam is mostly caused by inadequate exploitation and maintenance. The Palasari Dam has been in operation for 36 years since 1989. It utilizes the waters of the Tukad Sanghyang Gede River, which has a river basin area of 42.30 km2 and an average annual rainfall potential of 1,800 mm. The Palasari Dam has a total water volume of 8,000,000 m3 and is operated to meet the irrigation water needs of a 1,300 ha area. The stages of risk management include risk management planning, risk identification, risk analysis, risk handling, and risk monitoring. Risk identification is the initial step in implementing risk management. The results of the study showed that there were 35 risks identified in the operation and maintenance of reservoirs in Bali Province. There are 10 major risks (28.57%) occurring in the operation and maintenance of the Palasari Dam, and 25 minor risks (71.43%). The shallowing of the Palasari Dam is also due to sediment, resulting in a decrease in the benefits and functions of the Palasari Dam. Sediment control measures in the reservoir include technically inhibiting sediment upstream through the construction of check dams and embankments, dredging sediment based on echosounding measurement volumes, and managing the dam area with a land conservation concept.
