Abstract

The main issue in the operation of reservoirs is sedimentation. This can lead to silting and affect the reservoir's storage capacity. The distribution of sediments needs to be understood in order to gain an overview of their spread, so that measures can be taken to address sediment-related issues in the Jatibarang Reservoir. The analysis was conducted using sediment data from previous studies, which reported a total sediment volume of 6.64 million mÂł over a period of 50 years. Based on topographic data, it was found that the Jatibarang Reservoir is classified as Type III, with a "hill" classification. The analysis results showed that the dimensionless factor F is 0.22, with a relative depth p of 0.53. Based on the sediment distribution analysis of the Jatibarang Reservoir with Empirical Area Reduction Method, it was found that after 50 years of operation, the new zero elevation of the reservoir would be at an elevation of +126.82 m. In comparison with the low water surface elevation at the existing dead storage of the Jatibarang Reservoir, which is at +136 m, it can be concluded that the Jatibarang reservoir can operate according to the planned lifespan and can still function for more than 50 years

Abstract

Risk management is defined as a systematic process that includes planning, organizing, leading, and controlling organizational activities to minimize the likelihood of revenue loss. PT Mustiko Klopo Jati faces challenges related to improving construction risk management practices. The implementation of this activity is carried out in the Bulog Warehouse Construction Project. The objective of this community service program (PKM) is to provide risk management training with a focus on the preparation of the Construction Safety Plan (RKK). This training aims to enhance participants’ knowledge in preparing RKK documents in accordance with the latest regulatory standards. Before the training, 48% of participants had a limited understanding of the RKK preparation process; following the training, the level of understanding among construction practitioners increased to 85%. It is expected that this activity will provide solutions to the identified problems and foster effective collaboration with industry partners, thereby contributing to innovation in the implementation of efficient and appropriate construction practices.
