Abstract

Kupang City is the capital of East Nusa Tenggara Province located in Kupang Bay, based on historical data has encountered several of the earthquake that caused high tide. This study aims to obtain vulnerability of coastal society in land management of Kupang City coastal through those natural disasters, this study covers 15 villages located along the coast of Kupang City. Determination of the vulnerability using spatial analysis with GIS software Quantum Valmiera 2.2 and ArcGIS 9.3 , descriptive statistics, scoring systems and weighting limitation vulnerable areas under 10.5 meters above sea level, which is an overlay be physical vulnerability map. Physical vulnerability variable such as structured area, and the density of buildings.Non-physical vulnerability variable such economic area parameters, livelihoods, and population density. Environmental vulnerability variable parameters such as elevation, distance from the shoreline and coastal protection forest .There are three levels of vulnerability; high, medium, and low. From the resulting overlay of each variable and parameters obtained the vulnerability of coastal areas in Kupang City was dominated by the 9 villages with medium vulnerability, 1 village with high vulnerability, and there are no villages in the low vulnerability. 5 villages are safe from high tides.

Abstract

Cathodoluminescence (CL) is generated by visible light of minerals when they are bombarded with a beam of high energy electrons by a cathode gun. There are two types of chatodoluminescence, i.e., cold CL and hot CL. In the cold cathode microscopic equipment, the electrons are generated by an electric discharge between two electrodes under a low gas pressure, whereas in the hot CL microscope, the electrons are generated by heating a filament (2000-3000°C). This research to propose determine the growth of oolitic limestone’s cement by cathodoluminescence analysis and it’s implication to the engineering properties. Sectoral zoning and chevron-shape growth zoning exist in some coarse-grained calcite aggregates. The sectorial zoning of calcite as reflected by dull to bright CL color indicated as a water level fluctuation during cementation of the carbonate rocks, where the bright color of calcite indicating a shallower depth of water (oxidation) and dull to nonluminescence indicating a deeper level of the water (reduction). The results of this research, oolitic limestone (sample NS-1) showing sectorial zoning (chevron-shape) with at least 6 zonations, and have better engineering properties of other samples, according to SNI. 13-0089-87. Cathodoluminescence analysis is commonly used in the petroleum study, as evidenced in this research can be applied to determine the engineering properties of oolitic limestones in the study area.
