| Abstrak/Abstract |
Land use planning based on land resource evaluation and spatial orientation of planning as part of GIS may
ensures appropriate land allocation in order to achieve sustainable agriculture. The combination of some land resource
evaluation can provide final results on rational land allocation and land utilization based on land capability and suitability.
Land capability evaluation (LCE) and land suitability evaluation (LSE) approach rooted from USDA and FAO was used in
this study to allocated arable land as agricultural developed areas and determine prime commodities spatially. The principle
of limiting condition was used for LCE to define land class and determine land availability for agriculture. While, for LSE,
procedure of matching between land quality/characteristics
and crop requirement will be scored according to limitation
method and class criteria of land suitability in order to define the most suitable crop considered as prime commodity. The
objective of this study was to determine prime commodities at developed areas on the basis of information of land
resources at regional scale of 250, 000. With GIS application, the result of evaluation were then integrated into spatial
information as basic consideration for agricultural land use planning and further spatial analysis for agricultural land
allocation as well. This study was conducted in Central Kalimantan province with total areas of 15, 451, 287 hectares in
order to support policy of Indonesian Government for agricultural development especially for spatial agricultural land use
planning. The results of this studies showed that based on LCE approach, almost 61.94% of total areas (9, 571, 231
hectares) is arable land indicating that lands geographicaly have an opportunity to be developed. While based on LSE
approach and GIS application, there are 3 (three) prime comm
odities including their geographical distribution pattern that
suitable to be developed in Central Kalimantan involving wetland rubber (7, 355, 390 hectares), rice (2, 141, 539 hectares),
and oil palm (1, 722, 806 hectares). Appropriate programs in the scoupe of land use planning can then be formulated to
support agricultural development at certain areas.
