Abstract

Interaction between mainland and ocean are not balance. That means condition in mainland will higher affect the ocean, but not vice versa. Indonesia as a tropical island country has very long beaches and many rivers flow into the sea. The increased population in each province will have an impact on increasing contaminant into the river, so those are will cause the contaminant into the sea increasing. The problem statement is at what level of the marine environmental vulnerability in each province? Using methods of spatial analysis those find the spatial pattern of the marine environmental vulnerabilities in Indonesia. Level of the marine environmental vulnerability is generated based on numbers of regency along the coast line, including the total of population and population growth in each province and the number of rivers along the coast line. Conclusion in this research is province with the very high level of the marine environmental vulnerability is eleventh provinces, fifteenth provinces with high level, five provinces with moderate level, and two provinces with the lowest level. The province with very high level is caused by variation combination from the high number of regency along the coast line, including the highest number of population and population growth and the highest number of river. Such conditions may cause high vulnerability in some provinces such as Nanggroe Aceh Darusallam, Bangka Belitung, Kepulauan Riau, Banten, Bali, Nusa Tenggara Barat, Nusa Tenggara Timur, Sulawesi Utara, Sulawesi Tengah and Sulawesi Tenggara.Keywords: Vulnerability, marine environmental, spatial analysis

Abstract

Indonesia is known as a country with a strong in shipping, both nationally and internationally, which is shown by the number of coastal cities in Indonesia. Population growth in coastal cities in line with history of civilization who lived along the coast of Indonesia. Population growth led to expansion of the coastal cities in Indonesia, this increase affect land use change. Changes in land use, especially use of forest, will increase the use of setlement and agricultural caused an impact on increasing the contaminant throw into the river body or water body. Eventually cause contamination into the sea also increase, mainly going to affect the coastal environment around the coastal city. The objective is to find out coastal environmental vulnerability on coastal cities in Indonesia using spatial analysis method. First, count the number of population growth per year as index of population. Second, the number of land use change will be used as in index of change of land use. Third, count the number of river through the city and towards the sea coast, the results will show the index number of rivers. Index of population growth, land use change index and index number of rivers are combined and used to calculate the level of vulnerability of coastal environment around the coastal city spatially. The conclusion was that the higher the number of population growth, the higher of the landuse change and the most of rivers in the coastal city, that’s the higher the level of vulnerability of coastal environments.Keywords: coastal city, land use, river, environmental vulnerability

Direct collection for air surface temperature conducted by surveyingsome location collect in 24 hour period (April 2012) and another location by rapid 10 – 15 minute in day time(April, July, August and September 2012). This technique employed mobile temperature and humidity tools.Secondary air surface temperature data (24 hour period) during 2009-2012 also use in this study. Indirect dataemployed Landsat TM only two year data 2001 and 2012 for land surface temperature. Satellite data employedto identify land cover change to get information about land use change. The result shown that the temperaturecondition, both air surface and land surface temperature, were changed. UHI phenomenon in Tangerang Cityindicated by temperature higher than 300C. Based on land surface temperature, UHI phenomenon in 2001already occurred at small area. UHI phenomenon in 2012 almost covered the Tangerang City area. UHI Indexin 2009 is 3.60C, in 2011 is 1.50C and then 2012 become 1.20C. This study concludes that UHI phenomenafound since 2001 and trend of UHI Index AST since 2009 with average UHI Index AST of 20C. UHI Index LSTin 2001 is 9.780C and 2012 is 13.960C

Abstract

Peneliti Indonesia mengalami kesulitan dalam mencari referensi untuk jurnal atau paper yang ditulis oleh peneliti Indonesia sendiri. Hal ini disebabkan oleh kurangnya website yang menyediakan kutipan untuk paper Indonesia. Kurangnya komunikasi peneliti yang memiliki bidang yang sama juga berkontribusi untuk masalah. Gudangpaper.net adalah website yang memfasilitasi penyediaan makalah yang ditulis oleh peneliti indonesia. Untuk memecahkan masalah yang ada fitur social Network harus ditambahkan ke situs GudangPaper yang memungkinkan komunikasi dan membangun komunitas antara peneliti bidang sejenis di Indonesia. Protokol OpenSocial digunakan untuk juga mendukung komunikasi dan berbagi paper dan metadata paper dengan situs lain. Fitur jejaring sosial yang disarankan oleh paper ini adalah interaksi sosial antara penulis, membuat kelompok dan peneliti dapat berbagi kertas.
