Cekungan Bandung Urban Region is a national strategic area from the point of economic interest. Rapid economic growth in the region has led to increased population growth and Built-up land use. Increased use of built up land in urban areas can cause urban sprawl which can have serious impacts that will damage the structure and function of urban area ecosystems, thus hampering the development of regional sustainability. Landscape Metrics can be used to analyze the urban form of the Cekungan Bandung Area in time series from 1983-2015 so that it can identify the changing trends. The results of the analysis show that during this period urban growth in the Cekungan Bandung Area showed a positive trend with a compact, connected, un-fragmented and near-square urban form. Being a concern of Patch Density (PD) and CONTIG values because it shows an increasing number of patches so that patches are more fragmented and the distance between the built up patches shows the trend is increasingly scattered on the edges of the Cekungan Bandung Area which can cause urban sprawl.
The Bogor-Depok-Bekasi (Bodebek) region is a suburb of the Capital City of Jakarta located in West Java Province and part of the West Java development area (WP) 1, this region has experienced rapid regional development and economic growth due to the urbanization process in Jakarta. The development of this region was marked by the growth of Gross Regional Domestic Product (GRDP) of 42.08% and population increase of 19.54% during the period 2010-2016. However, developments in the Bodebek region have led to the formation of sprawl areas in several areas, leading to unsustainability and leading to the conversion of agricultural land. This study aims to 1) Identify and project Gross Domestic Regional Products (GDRP) growth and population based on a growth model approach using using simple regression equation; 2) Identify the spatial pattern of built-up areas in the Bodebek region by using the Moran index and the Local Indicator of Spatial Association (LISA); and 3) Identify development patterns in the Bodebek region using cluster analysis. The results of this study indicate that built-up areas in the Bodebek region are concentrated (clustered) in the core urban area of the Bodebek Region and its surroundings. In addition, population and GDRP growth in the Bodebek region follow the saturation growth model. Based on the result of cluster analysis, there are 3 clusters in the Bodebek region based on social, economic, population and land use data.
Robusta coffee is one of the focuses for realizing Desa Emas program in Mekarbuana Village, Tegalwaru Sub-District, Karawang Regency. The West Java Provincial Government choose Mekarbuana Village as one of the 20 target villages of Desa Emas (Enterpreneur, Mandiri, Adil and Sejahtera) in 2016. Robusta coffee production in Mekarbuana Village still fluctuates annually and certainly has an impact on the income of coffee farmers. A recommendation is needed in the direction of coffee development that considers various aspects of robusta coffee in the context of developing coffee commodities. The purpose of this study is to analyze the land suitability of Robusta coffee based on measurable soil chemical properties and provide recommendations for the direction of the robusta coffee development in an effort to realize the Desa Emas program. The land suitability analysis measured by taking disturbed soil samples to analyzed for the chemical properties of the soil and then conducted a land suitability analysis. Recommendations for the direction of the robusta coffee development are carried out by identifying strengths, weaknesses, opportunities and threats for the development of robusta coffee using SWOT analysis based on the results of land suitability analysis and interview result with coffee farmers in Mekarbuana Village. The results of the land suitability analysis indicate that actual land suitability has limiting factors, they are pH, slope, organic C levels, and water availability. Based on the SWOT analysis, increasing the quantity and quality of robusta coffee production in Mekarbuana Village requires various improvements in land input and maintenance.
