Abstract

Clustering slope stability in the Pangkalan Koto Baru, West Sumatra has become one of priority in disaster management. The method used for this study are using the combination of structural lineament analysis, scanline with window sampling and Rock mass rating (RMR) calculations. The analysis results of the fourteen observed slope sites showed significant outcome, which seen in the structural lineament show dominant trend from northwest-southeast, which also correlate from the measurement of discontinuity by using scanline with window sampling. From RMR calculation, value showed range between 17 - 42 which belonged to class V (Very Poor Rock) - class III (Medium Rock ). Integration data of structural lineament, scanline method and RMR analysis suggested that 1 slope included in the very poor rock category, 12 slopes are poor rock category, and 1 slope in the medium rock category. So, it can be ascertained that most of the slopes will potentially be prone to landslides. Keywords: Slope Stability, RMR, Structural Lineament, Pangkalan Koto Baru, West Sumatra.

Abstract

The research area was conducted in Ulu Melaka Village, district of Langkawi, Kedah Province, Malaysia. Coordinate of research area around latitude 99°45'97" to 99°45'04" N and longitude 06°25'05" to 06°20'00"E, with coverage area around 7 x 5 km. This research area is a suspected meteorite impact crater. The analysis begins by taking 7 rock sediment samples spread around the research area. The aim of research to find evidence of meteorite impact has fallen around research area use geochemistry method refer to the content of Rare Minerals of rock samples in the study area. Rock samples were processed using an X-ray diffraction (XRD) machine and run by EVA Software. Rock samples which have been analyzed were S1, S2, S3, S4, S5, S10, S19. Result of the analysis found four types of minerals formed by a meteorite impact consist of Jagoite, Dickite, Rubidium and Germanium Silicate Zinc Sulfide Diaminopropane. Jagoite and Dickite found in sample S2, Rubidium Germanium Silicate in sample S4 and Zinc Sulfide Diaminopropane in samples S10 and S19, respectively .
