Abstract

NTT is an area with relatively dry climatic conditions where the rainy season only lasts 3-4 months and the dry season is 8-9 months so it needs an analysis of the availability of water in each water source, one of which is the Borong watershed. The purpose of this study is to calculate how many mainstay debits are in the Borong watershed and find out the need for clean water in the area entering the Borong watershed area. There are two climatological stations that are influential in the Borong watershed, namely Stamet Ruteng and Wae Bobo / Borong. The data used has a span of time for the last 10 (ten) years, namely from 2007 - 2016 with the average rainfall of the two stations is 2132 mm / year, while the average Q99% discharge obtained is 2.258 million m3 / month . To calculate water requirements, the population data is used for 5 (five) years and projected for the next 20 (twenty) years. From the projection results, the current water demand is 0.00003 million m3 / month, while in 2037 it is 0.0011 million m3 / month. The water balance for clean water needs is currently experiencing a surplus of 2.233 million m3 / month, while in 2037 it has a surplus of 2.20 million m3 / month. Of the remaining water that will be used for the needs of irrigation water with an assumption of 1 liter / second / ha, the total irrigation area that can still be utilized is 257 ha with a minimum surplus in October is 0.002 million m3 / month. Thus it can be concluded that the water in the Borong watershed is able to meet the needs of clean water that is available and can still be used for irrigation water needs.

Abstract

Semalat Irrigation Area (DI) is an irrigation area located in Sungai Betung District, Bengkayang Regency, West Kalimantan Province with an area of 51.91 hectares. So far, there has been no determination of optimum cropping patterns in accordance with agricultural conditions in Semalat. Therefore, there is a need for research on an analysis of the determination of optimum planting patterns from several alternatives. Determination of the optimum planting system pattern aims to maximize agricultural land that is irrigated by irrigation so as to obtain increased crop yields with the need for efficient irrigation water. The choice of a number of alternative planting patterns is based on the time of the start of the planting period. There are five alternative cropping patterns proposed in the Semalat Irrigation Area, the first is the existing cropping pattern by starting the first rice planting on November 1, the first alternative by starting the first rice planting on October 15, the second alternative by starting the first rice planting in November 15, the third alternative by starting the first rice planting on December 1, and the fourth alternative by starting the first rice planting on December 15. Of the five alternatives proposed in Semalat, the optimum cropping pattern is the existing cropping pattern starting with the first rice planting on November 1 with a total irrigation water requirement for 51.91 hectares of rice field area is 86.17 lt / sec / ha.
