IV. RESULT AND DISCUSSION
This research is divided into three major parts: land suitability analysis for rubber plantation, productivity rubber analysis, and multi criteria analysis.
4.1 General Condition of the Study Area
4.1.1 Topography
The most important elements in topography are reliefslope and elevation. The relief is related to land management and erosion hazard, while elevation is
related to temperature and solar radiation and thus closely linked to plant requirements. According to the topography, Banyuasin Regency consists of 80
lowland in the form of coastal area, tidal swampy area are lowland at Banyuasin river stream consisting 20 of plateau and hilly area with a height ranging from
20 to 140 meter of above sea level.
4.1.2 Climate
Air temperature and rainfall data will be obtained from BMKG in Jakarta. The average air temperature in South Sumatra Province ranges from 25 to 27
C. Rainfalls throughout the year, the heaviest rainfall occurred during the rainy
season which lasts from November to April. For land evaluation, the required data
are annual rainfall and the number of dry and wet months. Oldeman 1975 climatic classes are based on the number of consecutive wet months and dry
months. The wet months are the months. This criterion is more applicable for annual crops. In the study area has tropical climate with variation of rainfall 1.97
mmyear – 13.32 mmyear.
4.1.3 Land Use and Land Cover
The main activity of traditional people in the study area is farming. More than half of the regency areas is utilized for agriculture, while the rest, less than
half of the area for non-agriculture including buildings, lawn and settlements. The width of agriculture area is 719.917 ha consisting of rice fields 270.548 ha, farms
33
197.452 ha; forests 57.627 ha; irrigation 77.050 ha, non-irrigated dry field and farm 50.258 ha unused land 99.982 ha.
4.1.4 Demography Condition
The demography conditions of study area is based on the population, total villages, total areas and average population per square Km as shown in Table 11.
