Indonesian national food sovereignty is very dependent on the supply of rice from paddy fields in Java Island. Various factors influence the farmer's decision to continue using his farm. This study aims to analyze the sustainable use of paddy field, determinant factors and strategies for improving sustainability. The study was conducted in Karawang Regency, one of the centers of rice production in West Java. The methodology used is a multi-dimensional scaling (MDS) using 43 attributes of 5 dimensions (ecological, social, economical, technological and legal and institutional dimension). Against the sensitive attribute analysis resulting from MDS, a prospective analysis was conducted to determine the key factors of sustainability. Priority policies for improving sustainability are developed based on the location of the key factors in the prospective diagram. The research results showed that the land utilization for paddy field in Karawang is actually less sustainable. Increasing the sustainability can be done through intervention and improving performance, preferably on sensitive attributes resulting from leverage analysis, covering 16 attributes. Priority policies is directed in the 5 key factors resulting from prospective analysis. Policies suggested are the tightening of new permits for building, strict implementation of the official spatial land use planning and delineation of agricultural land for sustainable food crops, counseling the community, revitalizing the role of BULOG, provision of subsidies as well as capital assistance to farmers.

The high rate of economic growth has encouraged the development of Baubau City in various sectors of life. It has implications on the increase in space requirements. Rapid changes in land use often deviate from the spatial plan (RTRW) that has been legalized. This study aimed to evaluate the appropriateness and consistency of the land use plan and to investigate factors affecting the suitability and consistency of the land use growth with the spatial plan. The analysis has used GIS, Balance of Land Resources, Factor Analysis, and Multiple Regression Analysis. Based on the analysis, there are three forms of inconsistency from the spatial plan of Baubau, as follows: inconsistencies in the spatial plan itself, inconsistencies with the laws and regulations, and inconsistency in the utilization of the land use plan. The results have shown that the level of consistency to the land use plan is medium. The factors affecting the deviation of land use pattern from the plan are the ease of getting to service centers, the improved welfare, and the accessibility.

Spatial plan is the result of spatial planning which is done through the process and procedure of arranging and determining based on the prevailing laws and regulations. The phenomenon that often happens is the deviation of existing land use with spatial plan. Sumedang Regency is experiencing a fairly rapid development, so there is an increase in human resource activity that implicate the widespread space needs and consequently deviation of land use is very vulnerable. The purpose of this study to determine the extent of deviation of land use occurs as well as what factors affect the occurence of irregular use of land. The analysis used in this study using GIS approach, Principal Component Analysis and Multiple Regression Analysis. The result of analysis shows that there are 25 types of deviation of existing land use and the most dominant is deviation into wetland (18,364 ha), dryland field (8,405 ha) and widened land (7,741 ha). While the factors that influence the occurence of deviation of land use are population and settlement, availability of land, infrastructure and accessibility, and sosioeconomic condition of society

Revitalization of agriculture is basically putting back the importance of agriculture proportionally and urban contextual in both rural and urban areas. Considering the existing condition of agriculture in urban areas, especially Jakarta Province, and linkages with its various environmental problems, it is expected that the development of agriculture would not be sustainable. Thus, it needs designation and formulation of a comprehensive policy for sustainable development of urban agriculture. The study is aimed to analyze the sustainability of urban agriculture as well as the critical factors affecting the sustainability and policy of urban agriculture development. The methods of MDS (multi-dimensional scaling) and Rap-Ur-Agri (Rapid Appraisal for Urban Agriculture) technique are employed for analysis. Meanwhile, key factor analysis uses leverage factor followed by determination of sustainable indices, and policy scenarios that use a prospective analysis method. The results show that the sustainability status of agricultural development on the existing condition of urban areas has an index value of 48.70 percent (i.e., less sustainable). The urban agriculture has four sustainability key factors, while attributes of stakeholders' needs have also four key factors. These eight key factors are merged yielding six key factors that influence the development of urban agricultural systems. Policy for sustainable urban agricultural development of Jakarta Province has to use an integrative approach with consideration of six key factors of agricultural sustainability, namely: (1) Yard acreage, (2) The development of commodity and environmentally sound technology, (3) Extension and agricultural institutions, (4) Availability of land area, (5) Cooperation among stakeholders, and (6) Provision of agricultural incentives. Policy options would encompass extension of land and space for farming, commodities and environmentally-friendly technology development, and agricultural institutional development.

Abstract. Infrastructure development does not only affect the economic aspect, but also social and environmental, those are the main dimensions of sustainable development. Many aspects and actors involved in urban infrastructure development requires a comprehensive and integrated policy towards sustainability. Therefore, it is necessary to formulate an infrastructure development policy that considers various dimensions of sustainable development. The main objective of this research is to formulate policy of sustainable infrastructure development. In this research, urban infrastructure covers transportation, water systems (drinking water, storm water, wastewater), green open spaces and solid waste. This research was conducted in Bandarlampung City. This study use a comprehensive modeling, namely the Multi Dimensional Scaling (MDS) with Rapid Appraisal of Infrastructure (Rapinfra), it uses of Analytic Network Process (ANP) and it uses system dynamics model. The findings of the MDS analysis showed that the status of Bandarlampung City infrastructure sustainability is less sustainable. The ANP analysis produces 8 main indicators of the most influential in the development of sustainable infrastructure. The system dynamics model offered 4 scenarios of sustainable urban infrastructure policy model. The best scenario was implemented into 3 policies consist of: the integrated infrastructure management, the population control, and the local economy development.

Abstrak : Pengendalian laju perubahan penggunaan lahan sangat diperlukan agar keberlanjutan lingkungan dapat tetap terjaga. Salah satu upaya untuk menjaga keberlanjutan tersebut adalah dengan mempelajari perubahan yang terjadi beberapa tahun sebelumnya.Perubahan ini dapat dipelajari dengan pendekatan model Markov -Cellular Automata.Kabupaten Cianjur merupakan salah satu kabupaten yang rawan terhadap bencana longsor, sehingga perlu dilakukan pengendalian perubahan penggunaan lahan agar dapat terwujudnya keberlanjutan lingkungan yang sesuai dengan arahan tata ruang yang telah ditetapkan. Tujuan penelitian ini adalah mengetahui perubahan penggunaan lahan yang terjadi dan mengevaluasi penggunaan lahan tersebut terhadap RTRW serta menyusun arahan pengendalian perubahan penggunaan lahan. Hasil analisis menunjukkan Kabupaten Cianjur mengalami penurunan luasan hutan yang cukup besar yaitu sebesar 10,3% dan ketidaksesuaian penggunaan lahan dengan RTRW sebesar 10,4%. Hasil prediksi memperlihatkan bahwa perubahan tanpa ada skenario menyebabkan persentase ketidaksesuaian penggunaan lahan meningkat drastis menjadi 20,5%. Skenario dimana dilakukan pengembalian fungsi hutan dapat menekan persentase ketidaksesuaian menjadi 16,6%.Kata Kunci: Pengendalian, Perubahan Penggunaan Lahan, Markov -Cellular Automata Abstract : Controlling the rate of land use change is necessary due to maintaining environment sustainability. One of the efforts is studying the changes that occur in the past few years. These changes can be studied by Markov -Cellular Automata model. Cianjur is one of the regency that has a high risk of landslide hazard, so it is necessary to control land use change in order to realize environmental sustainability in accordance with the spatial plan of Cianjur regency (RTRW). The purpose of this study was to see land use changes that occurred and evaluated with the spatial plan (RTRW) and also to conduct controlling scenarios of land use changes. The analysis showed that Cianjur regency has drastically decreased in forest area up to 10,3% and landuse inconsistency of 10,4%. The prediction results showed that landuse change without intervention would dramatically increase inconsistency up to 20,5%. Land use scenario of restoring forest could reduce inconsistency up to 16,6%.
