Judul: Spatial modeling of land use change in relation to spatial planning in Sukabumi Regency
Abstrak: Sukabumi Regency population growth of 1,14% per year have implies a growing demand of land to be used as built up area and other urban activities. The increase in housing needs have resulted in land use change from productive agriculture into built up area. This study aims to: (1) analyze land use changes in the period 2000-2010, (2) analyze the factors that drive the land use changes, (3) predict the use of land in 2032 using spatial models of land use change, (4) formulate directives refinement for regional spatial planning (RTRW) Sukabumi Regency. CLUE-S was used to simulate land-use change based on the driving factors. The results of the analysis showed there is changes in land use in the 2000-2010 period. The most extensive land use decline is rice field that decreased by 15,8%, the land use that decreased too is oil 0,4%, forest 0,5%, and others 2,7%. On the other hand, the land use that extensively increase is built up area that rise to 23,9% and dry land that increased 3,4%. The main pattern in land use change is from rice field into dry land or built up area. CLUE-S prediction produced an accuracy of 91,25%. Alternatives of policy that selected based on the study for the refinement of regional spatial planning is : (1) environmental oriented policies can reduced 4,54% of the incompatibility between land use and regional spatial planning, (2) food security-oriented policies can reduced 4,64% of the incompatibility between land use and regional spatial planning, and (3) combining environmental oriented policies and food security-oriented policies can reduced 4,65% of the incompatibility between land use and regional spatial planning.

Judul: Perubahan Penggunaan/Penutupan Lahan dan Faktor yang Mempengaruhinya (Studi Kasus: Kota Sukabumi, Jawa Barat)
Abstrak: The strategic position of Sukabumi City between Jabodetabek and Bandung Raya intensified the development in this region. It implied to the high of land use/land cover change (LUCC) in Sukabumi City. We utilized IKONOS in 2010 and 2012 to determine LUCC pattern. Furthermore, multiple regression was employed to find out affecting factors of LUCC. Skalogram analysis was then utilized to find out the level of regional development, descriptive analysis to correlate LUCC and level of regional development, and benchmarking of current utilization to evaluate the conformity of current land use/land cover with Spatial Plan (RTRW). The spatial analysis showed that within two years, built up area of Sukabumi increased at 2.8% while rice field and unproductive land decreased at 1.2% and 1.9% respectively. Factors affecting of LUCC in Sukabumi City were the availability of land; distance to CBD, allocation of Spatial Plan (RTRW); distance to economic, education, and medical facilities; regional development index; and the increase of population. Unproductive land change into agricultural land occured in 2nd hierarchy and 3rd hierarchy, whereas agricultural land change into built up area and unproductive land change into built up area occured in all of the hierarchy. Land use/land cover in 2012 conformed with RTRW was 36.6%, while 45.1% was undeveloped, and 2.3% was unconfirmed the plan.
