Abstract

The research design uses a descriptive quantitative approach, which explains the state of the efficiency of water distribution in Karang Bayan, Lingsar District, West Lombok Regency. The data used in the analysis are water flow velocity (VAV), cross-sectional area (A), channel flow rate (Q), water demand for plants and water requirements for each irrigation area, and the efficiency of irrigation water distribution in each channel (E). The results showed that the S3 and S4 channels did not meet the water needs in the irrigation area, while the discharge in the tertiary irrigation canals S1, S2, S5 and S6 was sufficient to meet the water needs of the irrigation area in Karang Bayan Village. Because the availability of water in the Mencongah Weir is very sufficient for providing water to the tertiary canal. Channel S1 which has an irrigation area of 36.64 ha and a channel length of 700 m with an actual discharge of 44.8 ltr/s has an irrigation efficiency of 60%. The S2 channel which has an irrigation area of 57,115 ha and a channel length of 900 m with an actual discharge of 67.9 ltr/s has an irrigation efficiency of 60%. In the S1 and S2 channels, the efficiency value is above 50-60%, then the channel can be said to be efficient

Abstract

Fresh water is one of most important and basic needs to support human life. With the growth of the population and the increasing rate of tourists in the KEK Mandalika area in Pujut District, there will be more and more need for fresh water every year.The purpose of this study is to determine the need and availability of fresh water for the KEK Mandalika area in Mertak Village and Kuta Village in Pujut District.  The results of the analysis shows that the population growth rate in 2027 in Mertak Village is 9,926 people and in Kuta Village it is 10,131 people.In this study, the total water needs are obtained at 131,992 lt/dt and the current water source is 481 lt/dt. Thus, the availability of water is surplus to water needs in Mertak Village and Kuta Village in the KEK Mandalika area, Pujut District and the needs of the ITDC until 2027
