Aplikasi Tata Air Sistem Elbow (TASEL), Saluran Keliling, dan Kemalir untuk Konservasi Air di Lahan Rawa: Studi Kasus Lahan Bergambut di Desa Talio Hulu

Abstract

Conservation of water and water level regulation is an important key to successful agricultural development in swampland. Several techniques to create embankments, blocks, and sluices are available and their application in the field is determined by hydrological conditions and characteristics of the area. Elbow Water System Application (TASEL) is a technique to create blocks and sluices for water conservation and regulation in tidal swampland. TASEL uses pipes as culverts and elbows as sluices. This paper discusses the application of the TASEL system in tidal swamp rice fields in Talio Hulu Village, Central Kalimantan Province. The location of this study is in secondary areas (ray) 39, 40, and 41 as a part of tidal rice fields. This area has been abandoned by farmers for 10 years, and the rice fields have been covered by various grasses and long-leaved paperbark (Melaleuca leucadendra), frequent floods, and fires. Soil type is dominated by peaty soil. The hydrological survey was carried out to determine the condition of the canals and inundation conditions in the plots of land. Furthermore, the pipe requirements, elbow requirements, and TASEL installation locations are formulated. As a result, 2 pipes and elbows were required for each hectare of land and were installed on the left and right of the rice fields. In addition, the perimeter ditches and micro ditches are made to facilitate the circulation of water in the rice fields. The combination of TASEL, perimeter ditches, and micro ditches can conserve water, regulate water levels, and provide water for plant growth.
