Judul: Dinamika Pola Penggunaan Lahan dan Pengendalian Perubahannya di Kabupaten Klaten, Jawa Tengah
Abstrak: Increasing population and regional development lead to soaring demand of land, despite the resource is limitedly available. The increase urges land use conversion to cater the interest of parties. Uncontrolled agricultural land conversion to other uses poses detrimental impacts in economic, social as well as environmental deterioration, which in turn requires a substantial cost. Therefore, land conversion needs to be tightly regulated. This research aims to observe the dynamics of land use change, to analyze the affecting factors, to predict and assess 2013 land use through Markov Chain analysis and to identify the role of stakeholders in controlling land use in Klaten Regency. It was shown that paddy fields and upland decreased by 1 425.37 (2.04%) and of ha 290.47 ha (0.41%) during the research period (1995-2009). On the other hand, waterbody, mixture-uses and settlements experienced an increase of 28.47 ha (0.04%), 13 ha (0.03%), 1 669.03 ha (2.38%) respectitively. Extensive forests and open land remains on 1 854.70 ha (2.65%) and 103.61 ha (0.15%) throughout the period of analysis. In general, factors affecting land use change are the distance to the city centre, slope, soil type, population, social and economical facilities growth. The pseudo squared distance (Nagelkerke) was R2 0.78%. Markov Chain generated accuracy at 82.67% for land use prediction. Moreover, to control land use of Klaten Regency, stakeholders believed that permits mechanism was the most important aspect at 38% of weight, followed by monitoring (33.73%) and curbing (28.25%). According to stakeholders, land utilization control required participation of governments (33.99%), people (19%), higher education (19%), NGO (18.87%) and private (16%).

Judul: Keterkaitan Antara Penyimpangan Penggunaan Lahan Terhadap Alokasi Ruang Dengan Perubahan Tingkat Kekritisan Lahan (Studi Kasus Kecamatan Babakan Madang dan Klapanunggal)
Abstrak: The basic function of spatial planning is an instrument to direct and control land conversion. But in fact, we found lots of mismatching among actual used and plan. The deviation could be due to various environmental problems, for such as land degradation. Land degradation causes the emergence of unproductive areas. This study aims to (1) find out suitability of spatial utilization in Kecamatan Babakan Madang and Klapanunggal at year 2000 to 2010, (2) identify physical environment variables to characterize degradation level of land, (3) understand the relationship between spatial mismatch between plan and utilization and degradation level. Several methods employed in this study included: (1) overlapping of spatial utilization map with spatial plan of year 2000-2010 to determine of spatial mismatch, (2) discriminant analysis to determine physical environmental variables characterizing degradation level of land, (3) overlapping spatial mismatch with level of land degradation to find out relationship between spatial mismatch with degradation level of land. The spatial mismatch in Kecamatan Babakan Madang, ware 0.57% on protected forest areas, 27.41% on production forest areas, 100% on plantation areas, 24.33% on dryland farming areas, 23.38% on industrial areas. The mismatch in Kecamatan Klapanunggal, were 12.23% in production forest areas, 5.19% in wetland farming areas, 40.97% in dryland farming areas, 24.88% in industrial designation areas, and 3.64% in rural residential areas. Physical environmental variables characterized level of land degradation were erosion rate, surface rock, effective depth, and rock exposed. The spatial inconsistence were increasing level of degradation when production forest area were utilized as residential, up land, and C excavation areas. In addition, the inconsintence of utilization in other areas did not increase level of land degradation.
