Time and Location Determination of Swamps Area Suitable for Paddy Field Using Remote Sensing Approach in Banyuasin Regency, South Sumatera Province

III. METHODOLOGY

3.1 Time and Location

This research was conducted from February until July 2011 in part of the swamps reclamation area in Banyuasin Regency which geographic location between 2 o 16 ’ 48’’ - 3 o 13’48’’ South and 104 o 46 ’ 48’’ - 105 o 32 ’ 24’’ East. Swamps reclamation areas in Banyuasin Regency consist of several locations that can be seen in Table 6.

This area is crossed by Anak Telang, Anak Kumbang and Anak Musi River. The detail of area of research can be seen in Figure 4. Research area Figure 3 Research area Figure 4 Detail of area of interest 20 The climate type of the area is tropical monsoon, hot and humid throughout the year maximum temperature ranging from 29 o C - 32 o C, minimum temperature from 21 o C - 22 o C and humidity around 84 - 89. The wet months over 200 mm rainfall per month occur during November – April and average driest month is August less than 100 mm rainfall per month. Average annual rainfall is about 2.400 mm. According to the Oldeman classification, the agro climate is C-1, with the 5 to 6 wet months rainfall over 200 mm and 0-1 dry months rainfall less than 100 mm. The climate and rainfall type supports a range of crops. The macro topography is generally flat or gently sloping towards natural drainage outlets. At micro level, the topography is very irregular and disturbed as a result of reclamation activities, e.g. the subsidence of mineral soils and the oxidation of peat. Human activities such as leveling and construction of sorjans further contributed to the disturbance of the original topography.
