Marginalization issue of green open space (ruang terbuka hijau/RTH) with a high level of land conversion to built space in urban area shows that there is no commitment of regional government on a sustainable urban development. Political commitment on the regional government is indicated among others by the weak support of green regional budgeting (APBD) related to RTH. The research was conducted in Bekasi City. The purpose of this research was to determine a model of environmentally sound regional budgeting policy strategy related to allocation of public RTH by using a hard systems and a soft stems approaches. The former was conducted by landuse changes analysis with the factors influencing them, by designing a regional budgeting based on RTH  allocating model structure by using a dynamic system approach and to formulate the direction policy using focus group discussion (FGD) and  analytical  hierarchy process (AHP). The results of landuse change analysis showed that there was an increase in built land area from 5,5% (1.157,77 ha) in 1989 to 70,7% (14.879,85 ha) in 2009. The determinants of landuse changes in RTH were population, educational facilities, markets, supermarkets, ettlements, industries, restaurants, hotels, and inns (R2 = 99,8%). The dynamic model also designed three scenarios of RTH  allocating  policy strategy  (pessimism,  moderate, and optimism) with a early simulation in 2010. The  optimism  scenario was considered as  being capable of accommodating the fulfillment of city  RTH need  really on an assumption of considerable long multiyears budgeting so that in 2030 the target of 20% public RTH would  be achieved. The  results of analysis by AHP and FGD approaches  showed that alternatives were on 2 main policies, namely: agriculture/RTH infrastructure development and RTH land acquiremen.

Planning analysis to increase rice production either through intensiḀcation of existing paddy Ḁeld area or ex-tensiḀcation in potential land area was conducted in West Lombok Regency, West Nusa Tenggara Province, Indonesia. Existing paddy Ḁeld was delineated using high-resolution data from IKONOS imagery of 2012. Land use and land cover outside existing paddy Ḁeld were interpreted using SPOT-5 imagery of 2012. ἀe Automated Land Evaluation System (ALES) was used for land suitability analysis for paddy. ἀe results are interpreted in terms of the potential of paddy Ḁeld intensiḀcation in existing paddy Ḁeld area and the potential of extensiḀcation in land potentially used for paddy Ḁeld. ἀe result of analysis showed that in West Lombok Regency, there are still possible to do intensiḀcation and extensiḀca-tion of paddy Ḁeld to increase rice production in order to improve regional food security.

Mangrove ecosystem has role of interface ecosystem between land and sea. Some anthropogenic factors are responsible for the damage of mangrove ecosystem. The purposes of this research are to explore the performance of the biophysical mangrove ecosystems at Birem Bayeun and Rantau Selamat Sub-District, East Aceh. Some analyses done in this study are: the analysis of vegetation, environment properties, and analysis of area and distribution of mangrove. The results show that mangroves in the study area consist of 10 species, in which R. apiculata and B. gymorrhiza have dominant species in the study area, Importance Value Index (IVI) that is higher than the other species. Based on the interpretation of citra image, width of mangroves in the study area has been reduced. Biophysical properties of the mangrove area were suitable for mangrove growth (Physical-chemical properties of the soil, the chemical properties of water (salinity), inundation class and the frequency of tidal).Key words : anthropogenic, biophysical, ecosystem, mangrove.
