Abstract

The purpose of this service is to participate in the maintenance of the Batujai dam, Central Lombok Regency. The method for carrying out this service is to be directly involved in dam maintenance, especially regarding gates, channels, vegetation, walls and flood control. The service carried out is limited to light, simple and short maintenance such as maintenance of secondary channel sluice gates. Sluice gate maintenance is limited to cleanliness and lubrication. Other maintenance that can be carried out is related to the vegetation around the dam. Large amounts of vegetation also cannot be carried out due to time, cost and equipment constraints. Maintenance of walls, channels and irrigation systems requires time, money and adequate tools so it cannot yet be realized

Abstract

Hydrological analysis is the most important measurement in determining runoff in order to find ways to overcome flooding. The flow rate that is the basis for calculating flood control and protection is the planned flood flow rate obtained from the sum of the volume of rain runoff and the flow rate of the water catchment area in question during a certain return period. This research is a case study using rainfall data for 10 years, namely 2014-2023. Rainfall prediction is an estimate of the amount of rain that will fall in a river basin. There are several methods for determining annual rainfall, the Gumbel distribution method, Pearson log type III, and the normal method. After analyzing the annual rainfall data obtained at the West Lombok Regency Meteorology, Climatology and Geophysics Agency office, using three methods, namely the EJ Gumbel method, the Log Person Type III method and the Normal method, where from the three methods the maximum rainfall difference was quite large, In the following table you can see the difference in the amount of maximum rainfall in the return period T years.
