ANALISIS FAKTOR PENYEBAB DAN DAMPAK PERUBAHAN PENGGUNAAN LAHAN PERTANIAN PINGGIRAN KOTA YOGYAKARTA
Abstract: The problems of the
study are: (a) how the peri urban agricultural land use changes, (b) what
factors influence land use cahange, (c) how the impacts of the land use changes
on regional food lost, food availability, and the prospects of the farming
sustainability in the peri urban area ofYogyakarta city. The objectives of the
study are (a) to estimate the area and the rates of the peri urban agricultural
land use change, (b) to estimate the factors influencing the land use change,
and (c) to estimate the impacts of the peri urban agricultural land use change
to the regional food lost, regional food availability, and the prospects of the
farming sustainaibility in the peri urban area of Yogyakarta city..The data
collection methods used in this study are: (a) Landsat TM satellite Images
analysis, (b) digitally map overlaying on computer screen using Geographic
Information System (GIS), (c) documentation of secondary data, (d) interview
with quetionare as the guide, and (d) field observation. Data will be analyzed
by using the mathematics, statistics, and econometrics equations specially
multiple linear regression. Data will be presented as the table, diagram, curve
and map.The results and conclusions of this research are (a) the changed of
peri urban agricultural land use as long as 11 years from 1996-2007 are 922,17 ha
in Sleman; 1.888,60 in Bantul; and 1.082,79 ha involving 47 sample of villages;
the rates of land use changing is in negatif correlation with the the distance
from the city, (b) the used econometric model in this research indicate a
satisfaction goodness of fit with R2 of 0,895. Based on the analysis of
variance, F-test, and t-test can be conclude that some factors i.e. Exhange
Value of Agriculture Production (FPV), Technical Irrigated Agriculture Lands
(IRG), the Precentage of Built Area to the Agriculture Lands (BCPr), People
Density (Dens), Society Education (Edu), and the Agriculture Land Price (FLP)
significantly influence to the rates of agriculture land changes, but the other
factors i.e. the Precentage of agricultural lands to the village area (FLPr),
Agriculture Lands Tax (FLT), Dummy of Bantul (DB), and Dummy of Kulon Progo
(DKP) do not significantly at the α of 5-10%, and (c) the rates of agricultural
lands changes have negative impacts to the regional food lost, regional food
availability, and the prospects of the farming sustainability of peri urban
agricultural lands. The number of regional food lost equivalent with 703,443
people, and the decreasing of regional food availability is equivalent with
572.259 people.
