Parek Village is one of the Disadvantaged, Frontier, and Outermost (3T) areas in Landak Regency, West Kalimantan. This village is not reached by the PLN electricity network. To meet electricity needs, in 2011 a 40 kVA capacity PLTMH unit was built in Parek Hamlet and continues to operate until now. To ensure the success of the PLTMH construction in Parek Hamlet, it is necessary to evaluate the existing PLTMH. This evaluation aims to determine the physical condition of the PLTMH and the technical performance of the PLTMH. This study uses primary data, to obtain primary data, namely by survey and direct measurement to the field to obtain data on water discharge, waterfall height, current, and generator voltage and directly see the condition of the components used in this plant. The evaluation results for the dam, Intake, Forebay, Penstock, and Generator house are still in good condition. The overall condition of the main components such as generators and turbines is still working properly. From the results of the measurements taken, the water discharge from the average of each segment is 0.6824 m3/second and the height of the waterfall is 2,8038 m. The results of the calculation of the potential power that can be generated is 12,8384 kW from 32 kW of installed power. While the usage load used by the community is only 5,842 kW. The comparison of the power used by consumers or the local community with the power that can be generated theoretically is 45,5%. This is because the majority of people there have a low economic level. So residents who use electricity from PLTMH only use it for lighting.
