Daftar Isi:
- The research was carried out in the coastal zone of Demak, Central Java Province. The research objectives were (1) to map existing condition of mangrove area and its changes in the coastal zone of Demak, (2) to describe the requirements of growth and development of mangrove ecosystems in the coastal zone of Demak which should be prioritized in treatment, (3) to determine the areas that should be a top priority in rehabilitation of mangrove ecosystems in the coastal zone of Demak, and (4) to determine the management strategy of mangrove ecosystem in the coastal zone of Demak. This research used a survey method. The data collection used sampling and the analysis data used qualitative analysis. The population is the overall of Demak coastal zone that consist of the land physical characteristics and the community characteristic. The sampling techniques of the land physical characteristics used purposive sampling method. While the sampling techniques of the community characteristics used simple random sampling method to determine the respondent. There are several kinds of data collection techniques that used in this research, namely: interpretation of multitemporal satellite imagery, map interpretation, analysis of secondary data, field observations and interviews. The variables of this research include physical factors, factors of community characteristics and vegetation factors. The techniques of data analysis applied Geographic Information System analysis which includes buffer analysis, scoring analysis and overlay analysis. The results show that the mangrove ecosystems in Demak coastal zone are 1,979.58 ha in 1994, 1,077.28 ha in 2002 and 1,159.23 ha in 2010. The requirements of mangrove growth and development of mangrove ecosystems in Demak coastal zone consist of: (1) marine landform, (2) rainfall 1000 � 3000 mm/year, (3) average salinity <0.01 � 33�, (4) water temperature 25�C � 33.3�C, (5) the soil substrates of silt and clay, (6) the soil texture of silty clay, (7) tidal range <2 m, (8) inundation height <2 m, and (9) land use of fish ponds and salt ponds. The priority areas of mangrove rehabilitation program in Demak coastal zone consists of: (1) the first priority occupy in Wedung Subdistrict, in greenbelt area that has not planted mangroves and in the very potential land for mangrove ecosystem
