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

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 upstream of Cikapundung sub watershed is the high land which is located on the North of Bandung Area. The soil is fertile, therefore the land is used as farming. The agriculture land is slope and the farmers have not applied the technology of conservation yet, as the result the soil susceptible to erosion. Consequently it decreases the productivity of land. The objectives of study were: (1) to evaluate erosion (value and risk erosion) at the use of land existing and (2) to investigate soil destruction level by erosion and its impact to productivity of land at upstream of Cikapundung sub watershed. The research used survey method. The data consisted of secondary data and primary data. The secondary data was collected through desk study, whereas primary data was collected through interviewed farmers, the soil observation, and soil sample analyses that is included the contain of sand, dust, and clay; C-organic; and nutrient content (N, P, K, and Ca) at Laboratory. The data analysis was done according to descriptive. The result showed that the most soil erosion was at the type of vegetable land use which use intensively at slope 25-40%.Value erosion roundabout 22.57-597.76 ton ha-1 year-1 or 0.33-8.79 cm. Level of destruction soil by erosion at upstream of Cikapundung sub watershed majority was medium critic (the upper soil was loss >75%) and spread at some units land. During five years, the impact of erosion decreased C-organic 60.05%, N 44.7%, P 52.3%, K 24.7%, and Ca 27.2%. Productivity Potato decrease 60%, whereas cabbage 40%.
