KAJIAN KESESUAIAN LAHAN IRIGASI RAWA PASANG SURUT BERDASARKAN POLA RUANG DI DELTA TELANG II KECAMATAN TANJUNG LAGO KABUPATEN BANYUASIN

Abstract

Indonesia has over large lowland areas with an estimated average of about 34 million ha, out of which about 20 million ha is tidal lowland spread throughout most of the Indonesian archipelago. The lowlands of Sumatra and Kalimantan started reclaimed in the early 1970s and 1980s with the main objectives to support the transmigration program. One of provinces with promising potential tidal lowland is South Sumatra, where Delta Telang II is one of several existing tidal lowland irrigation scheme. Delta Telang II is a sedimentation land of two rivers in Tanjung Lago Sub-district consisting of 12 transmigration villages. The purpose of this study is to review spatial plan based on land suitability in the tidal lowland area of Delta Telang II, Tanjung Lago. The method applied in this study is the method of mix method, adapted to the characteristics of the research approach and technique analysis. Result of a comparison between land suitability map and spatial plan of RTRW Kabupaten Banyuasin shows a significant difference. Recommended land use in spatial planning of Kabupaten Banyuasin mainly propose  for paddy fields with an area of 9,631.47 ha, while based on the result study dominantly propose for palawija with approximate area of 7,328 ha. This is happen due to the higher topography compared with mean high water level in Banyuasin river.
