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: Dinamika Perubahan Penggunaan Lahan dan Kecukupan Usahatani di Kabupaten Subang
Abstrak: Subang regency is located adjacent to Jakarta on the north coast of West Java. This strategic location has positioned Subang for having an added value of easy access. Therefore, it is exposed to increasing regional growth and development. Approximately 11,250 ha of the area have been allocated in a spatial plan as industrial area. The allocation causes land alteration, primarily in agricultural fields. Considering its significant impact, land conversion needs to be controlled. This research aims to observe the patterns of agricultural land use change in Subang during 2007-2013, as well as to study factors affecting land conversion by using logistic regression and to identify farmer’s interest to maintain their agricultural land. Analysis of land use conversion in 2007-2013 indicates that mixed garden and built-up increased considerably. These rises consume other land use types, including plantations, rice fields, and dry land agriculture. Other land use types remained constant. Logistic regression analysis concluded that the change of agricultural fields to built-up was influenced by several factors, including soil type, spatial plan and distance to the capital city. While factors affecting the interests of farmers were net agricultural income, total production and landrent. The Markov Chain accuracy in predicting land use of 2013 in Subang regency as much as 96.4%. This method is fairly accurate in predicting the use of mangroves, ponds, and forests
