Pengendalian Pintu Air Untuk Mendapatkan Ketinggian Dan Debit Penampung Air Sawah Di Bangunan Pembagi Pada Kecamatan Sei Bingai Tampa Goni Kabupaten Langkat

Abstract

The floodgates at the Pasar IX dividing building Sei Bingai Subdistrict Tampa Goni Langkat Regency North Sumatra Province irrigates downstream one-door irrigation channels to irrigate the water reservoirs into rice fields with the problem of lack of control of the floodgates in the divider building well due to the distance of the building responsible for, lack of the resources that guard the flood gates, and the lack of knowledge of the residents in controlling the flood gates in getting the height and water discharge that is in accordance with the needs of paddy fields. The building has 5 sluice gates which are 4 sluice gates directly into the irrigation channel and 1 sluice gate leading to a paddy field with a 4.24 m /s discharge manually, from a paddy sluice having 3 sluice sluice gates out 1.25 m 3 /s. The scope of this study is to control floodgates to get the height and flow of water holding rice fields in the building dividers aimed at knowing how to control water in the building for manually becoming automatic discharge that comes out 5.29 m 3 /s which with the benefit of helping the person in charge of the building for and community in controlling the floodgates to the rice fields. Theoretical description supports the method in controlling floodgates with buoys including water discharge, buoy volume, buoy lift force, buoy tumbling force and gear to solve the problem of poorly controlled water discharge according to the needs of paddy fields.
