5.5.4 Landuse Suitability
Landuse suitability is determined by the sum of the scoring soil type, precipitation scoring and land slope scoring. Scoring and criteria for the results of land suitability
recommendation can be seen in the Table 5-6. Table 5-6 Landuse Suitability Scoring Ditjen RLKT, 1986
Land Suitability Recommendation
Scoring and Criteria
Protected Forest A Total scoring 174, or
Elevation 2000 m, or Slope 40 , or
Slopes 15 and soil type susceptible to
erosion Buffer Area B
Total scoring 125 – 174, or Nature Preservation Forest and Tourism Forest
Settlement D Total scoring 125, or
Do not have a system or having a potential for
agricultural development The result of landuse suitability analysis can be shown as a Figure 5.30 :

Based on the analysis, it is found that some of the recommendations are buffer area of 4.17 km

, protected forest area of 7.35 km

and the rest is recommended as a settlement area in the downstream of Buper Watershed.

0,04 Based on the land characteristics of non- groundwater basin, which have a
thickness of thin soil, its sensivity to erosion and a few kind of plants that can survive in the savanna area. Plants that survive are the plants that able to live with the condition of the
thin soil layer. Here are some plants that can grow and hard to grow areas of savanna Buper Watershed :
A. Eucalyptus can lives and grow well.
B. Crop is failed to grow properly
Figure 5.31 Vegetation of Buper Watershed In the buffer area which is located in the savanna, not all plants can grow well. This
has been proved by Forest Departement program which has failed in crop planting. The trees were failed to grow properly. But the local native plants such as eucalyptus can grow
in Buper Watershed, so that the buffer area in savanna land cover is not appropriate for crop planting.
