3.3.2 Analysis of Existing Land Use Types
An inventory of existing land use was conducted using current land use and verified by field observation. Existing land uses were classified and
the extent of their acreage determined as depicted Figure 6
. The result of existing of land use analysis is used to the next analysis i.e., existing of rubber analysis.
In Figure 6, eight dominant existing land use types are identified: mixed gardens 136,666 ha, settlements 38,533 ha, mangrove forest 122,212 ha,
plantation 105,927 ha, shrub 351,588 ha, paddy field 198,472 ha, swamp 11,346 ha and bare land 26,573 ha. Map of land use in Banyuasin Regency
please see Figure 6. Based on the observation, it is known that mixed gardens could support
annual income; mangrove forest could supports soil erosion control; plantation provide rural employment and export commodities and soil erosion control; paddy
field support annual income and food availability; bare land supports food availability for livestock. Therefore, these land utilization types were selected as
proposed land use types to solve environmental and economic problems in the area. In Figure 7, shrub cover an area of 351,588 ha which should be developed.

3.3.3 Existing of Rubber Plantation
The Spot image was classified using Supervised Classification technique into several types of plantations. The classification processed was completed by
land use data, areas statistic data, which obtained from the Banyuasin local government.
In supervised classification the process was validated by defining the spectral characteristics of the classes by identifying simple areas training areas.
After that, all vector data required were extracted using spatial processing software. The existing of rubber plantation data resulting will be used for the next
spatial processing.
