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.

Growth of Makassar City as metropolitan have been increasing urban economic growth and social community change, however, it caused problems non-bus public passenger transport management policy not integrated with urban spatial planning policy as one unity. Research objectives are aimed to design model of sustainable transportation management for non-bus public passenger transport integrated with urban spatial planning, to evaluate existing route pattern performance and to identify and to manage potentially polluted corridor from emission gas. Research methods consist of three phases namely valuating of route performance with descriptive analysis, identifying gas emission and zoning management with level of services, hierarchy analytical process (AHP), and designing priority policy model with geographic information system (GIS) and exponential comparative method (MPE). The results are: (i) the road level of services performance with the bigger traffic composition are motorcycle and non-bus public passenger transport and densities of primary roads as compared to secondary roads with level of services of C, B, and A for variation between collector and artery roads; (ii) vehicle emission as standard of very small as compared to step over standard and gas ambient by CO are sedan/jeep, kijang, pick-up, bus, non-bus public passenger transport and mini bus, and mini truck on the artery road, (iii) the priority alternatives on zoning arrangement are first for environmental facility improvement, vehicle arrangement, location decision, and institutions arrangement; (iv) model of sustainable transportation management with GIS is spatial database and transportation maps of selected route and zoning arrangement whereas policy priorities are regarding management aspect improving level of service which consider road capacity, real speed, and volume ratio and regarding policy aspect ascertaining spatial plan as a dominant factor for zoning arrangement in relation to vehicle pollution. Key words: non-bus public passenger transport, sustainable, spatial, route, emission

In the framework of regional development, only few of villages which developed by transmigration program expands as Indonesian government expected. Some problems are remote location with poor access, unfertile soil, and lack of supported socioeconomic infrastructure to develop farm enterprises. This research aims to analyze a growth of countryside level, agriculture activity, a society participation and aspiration, and to compile an area development instruction. The result shows that Bukit Makmur countryside has the highest hierarchy. As far as village area from the service center, it has a lower growth of countryside level. Most of people in the village hope to participate in development of their region, especially in developing of prime commodity such as oil palm which is plant in second arable land through a partnership with some investors which is facilitated by the government. East Kutai local government policy in developing area stated that Kaliorang transmigration area as a part of development area of Sangsaka Agropolitan. Infrastructure especially in transportation is a main problem, because of in developing area as an agribusiness district needs a supporting infrastructure upgrading and development and transportation facilities. Key words: Kaliorang transmigration area, prime commodity, infrastructure development

Optimization of dry land utilization in Indonesia including in Bogor Regency is generally still has a lot of constraints. One of the causes is land degradation. At the moment, land degradation inventory is still resulting tentative acreages, since the criterion and overcome priority were different among institutions. This research aims (1) to know variables affecting level of land degradation, and (2) to compose criterion (classes range) andclassification of land degradation level in dry land both for reconnaissance and semi-detail scales based on variables affecting level of degradation. The research was conducted at three subdistricts, namely Sukamakmur, Babakan Madang and Cigudeg subdistricts. Data was collected on surveys through a case study. Biophysical data and soil samples were collected at60 key regions (derived from 3 subdistricts x 5 land critical levels x 4 replications). On each key region, undisturbed and composite soil samples were collected, altogether 60 undisturbed and 60 composite soil samples. The data were analyzed using discriminant analysis and cluster analysis. This research was resulting three criterions (range of classes) for five variables determining level of land degradation for reconnaissance and eight variables for semi-detail scales. The five variables for reconnaissance scale were type of bedrock, slope, conservation practices (P-value), silt percentage, and land use/vegetation (Cvalue). The eight variables for semi-detail scale were type of bedrock, slope, conservation practices (P-value), silt percentage, land use/vegetation (C-value), P-available, exchangeable Al, and H. This research had also generated three degradation levels for reconnaissance and semi-detail scales. The classification of land degradation for reconnaissance scale were (1) slightly degraded land (score <16), (2) moderately degraded land (score 16-39),and (3) strongly degraded land (score >39). Whilst, the classification of land degradation for semi-detail scale were (1) slightly degraded land (score <15), (2) moderately degraded land (score 15-38), and (3) strongly degraded land (score > 38).

This study aims : (1) to analyze the status of coastal ecosystems, (2) to analyze factors that affect the quality of coastal ecosystems, and (3) to prepare the direction on spatial planning in coastal areas of Ambon Bay Area.The analytical method used in this study is the analysis of ecosystem status, principal components analysis, analysis of Geographic Information Systems (GIS) and analysis of dynamic systems.The results showed that the condition of ecosystem status damaged in 2008, whereby, the status of mangrove ecosystems is moderate with a density of 1100 trees/ha, the status of seagrass ecosystems damaged by percentage cover of 38,76%, and the status of coral reef ecosystems are damaged by the percentage of live coral is 42,27%. Ecosystem conditions in Ambon Bay Area is affected by land use on land, namely forest area and population.Refferral of land use planning in Ambon Bay Areas wich recommended in this study for a period of 20 years of protected areas and cultivated areas. Protected areas is aimed at 9.480,70 ha or 41,21% of land area, while the allocation of space for the cultivation area is 10.416,30 ha (58,79% of land area). To reduce the pollutant into the waters, planned buffer zones (coastal and riverine border for 11,69% of land area), which serves to absorb pollutants and protect the inland waters of the tidal influence, while still controlling the waste coming into waterBy using dynamic systems analysis, created the scenario of land use planning in Ambon Bay Area that integrates land and wet land. The scenario used in this study is the optimistic, pessimistic and moderate scenarios. The variable that is used to determine of policy scenarios spatial planning based on the rate of population growth is 2,5% per annum, while variable forest area of at least 30% of the area. Of the three scenarios, the scenario chosen for the land use planning policy in Ambon Bay Areas in the future is to use the moderate scenario. The simulation results moderate scenario, the status of coastal ecosystems is improved from the criteria of the coastal ecosystem damaged by coastal ecosystems index 44,44% in 2008 turned into good condition with the index of coastal ecosystems 88,89% in 2029

Landuse is a manifestation of relationship between human activities and environmental changes, like erosion. Impact of landuse change to erosion was already happened, such as decreasing of soil fertility, flood at low land. An anticipation of landuse change was one of several alternatives that can minimize erosion. The objectives of this research were to analyze the impact of landuse change and to create the recommendation of landuse that can minimize erosion. Prediction map of landuse on 2018 and 2030 were obtained from previous research. Erosion rate were caluculated based on Universal Soil Loss Equation (USLE). This research predicted that landuse change could increase erosion rate, with asumsion if no change in term of RKLS values. The actual erosion rate (A) were 149,7 t ha-1 year-1 (2006), 154,4 t ha-1 year-1 (2018), and 159,2 t ha-1 year-1 (2030). This erosion rate were 3,7-4,9 times bigger than the tolerable erosion rate (TSL = 40 t ha-1 year-1). Modification of C and P values could minimize the actual erosion rate (A) until less than the tolerable erosion rate (A<TSL). Results of this research could be used as input for landuse planning, especially for landuse that would increase erosion rate.
