| dc.description.abstract | Nowadays, the population of the world is growing dramatically. Under
present situations, where the land is a limiting factor, it is impossible to bring
more area under cultivation (extensive farming), so farming community should
tackle this challenge of producing more and more food with the available land
only (intensive farming).
Bantul regency which one of the food source in Yogyakarta has
undergone rapidly tremendous economic growth during last few years. This
condition caused the decreasing of agricultural areas to industrialized, tourism and
settlement areas.
The objective of this research is to explore the geographic information
systems on defining potential agricultural area based on land suitability and
revenue cost analysis in Bantul Regency.
Land suitability analysis is a prerequisite for sustainable agricultural
production. It involves evaluation of the criteria ranging from soil, terrain to
socio-economic, market and infrastructure. Many of these factors are vaguely
defined and characterized by their inherent vagueness. Multicriteria decisionmaking
techniques like weighting, ranking, rating etc. are employed for suitability
analysis. Simple Additive Weighting (SAW) or Weighted Linear Combination
(WLC) is the most often used technique in multi-criteria decision making. As this
process incorporates expert knowledge and judgment by decision makers at
various levels, it is very much subjective in nature. Revenue cost analysis is
needed in this research for determining agricultural potential area, in order to get
the maximum benefit out of the land in the research area which had several land
suitability level of several crops.
The result of this research showed how land suitability and revenue cost
analysis approach were very useful to determine the agricultural potential area in
Bantul Regency. The agricultural potential area consists of potential area for corn,
rice, soybean, and peanut. | id |
