Abstract

The aim of this research is to know soil permeable system in the field by Auger Hole method in the Secondary Block P17-6S Banyu Urip Village Tanjung Lago Telang II sub district of Banyuasin district. This research was conducted in the tidal lowland reclamation area on P17-6S Banyu Urip Village Tanjung Lago Telang II sub district of Banyuasin district from September 2011 until Maret 2012. The method used was detail survey method by using map scale 1: 25.000. The large of research area is 256 ha. The distance used to take sample is 2 ha / point of boring with grid method or line stripe by depth 0-120 cm. The result shows that soil texture was dominated by texture of sandy clay in the Banyu Urip Village and the highest of pour out rain happened between January 252 until June 158 mm bulan'1 and the lowest happened between July 26 until September 6 mm bulan'1. The system of water net in the Banyu Urip Village used ladder system by order of channel’s nam. They are Primer, SPD (channels rural areas), Tersier, SDU (Main Drainage Channels). The net condition, operation order and breeding cultivation handled by farmers. The result of measurement of soil hydraulic conductivity value in the field Auger Hole method is precisely, It’s caused by many factors that influence it such as water circulation, water road and soil condition in the field when boring that consist the rest of the plant roots and cracks. The average point of lst tertiary until 16* tertiary dominant with average criteria in range (2,18-6,29) cm/hr and the highest point consist of in 10* tertiary (6,29 cm/hr). the minimum point from lst tertiary until 16,h tertiary dominant with slow criteria in range (0,61-2,08) cm/hr and the highest point consist of 12th tertiary (2,08) cm/hr. the maximum point of lst tertiary until 16* tertiary dominant with average criteria in range 2,16 until 8,24 and the highest point consist of 3rd tertiary is 8,24 cm/hr. The lowest of soil hydraulic conductivity value at point 12 with the 0,61 cm/hr slow criteria consist of in 2nd tertiary, the condition is caused by dusty clay texture, always flooded so that the soil pore space occupied by the granules dissolved in water passing through the pore and steadfast color grayish brown. The highest soil hydraulic conductivity value at point 80 with the 14,15 cm/hr average criteria consist of 10* tertiary, the condition is caused by loamy clay texture have ability to hold water better than dusty clay and steadfast color grayish brown.
