Abstract

This study aims to analyze and map the peak ground acceleration using the approach of Probabilistic Seismic Hazard Analysis (PSHA) in the area. Earthquake catalog data obtained from BMKG, ISC and USGS began in 1914 until 2014. Declustering process using ZMAP ver.6 software. Identification and modeling of the seismic source uses three models of seismic sources: (1) to subduction earthquake source, (2) the source of the earthquake fault and (3) the source of the quake background. Parameters a-value and b-value is obtained by the Gutenberg-Richter recurrence law and maximum likelihood method, whereas the determination of the attenuation function and logic tree refers to the Revision Team of Indonesia Earthquake 2010. Peak ground acceleration values obtained using USGS-PSHA-07 software. The results showed that the value of the peak ground acceleration in the Kepahiang District for probability exceeded 10% and 2% in the 50 year design life of the building is 0.15 – 0.8 g and 0.25 – 1.3 g. Areas that are the red zone is the Ujan Mas Sub-district, Kepahiang Sub-district, Tebat Karai Sub-district, Seberang Musi Sub-district and Bermani Ilir Sub-district, while the regions are relatively safe from the red zone is the Merigi Sub-district, Kabawetan Sub-district and Muara Kemumu Sub-district. Red zone is an area adjacent to the Sumatran Fault of Musi Segment. Keywords: peak ground acceleration, PSHA, red zone and Sumatran Fault of Musi Segment.

Abstract

The determination of crystallography structure of AlMg2 alloy has been done by neutron diffraction. In fabrication process, it was addressed by rolling phases. The first by hot rolling with thickness follows: 8.35 mm; 7.00 mm; 5.6 mm; 2.60 mm; 1.65 mm ± 0.05 at  425 0C temperature extended by cold rolling: 1.65 mm to 1.30 mm ± 0,07 thickness at normal temperature. Counting of the data was started by activate of detector from 110 to 400 angle with 0.075 overstep and preset monitor count of 60,000 at 26 MW. Processing of the data using of microcomputer 16 bit NEC PC-9801 VM2. The results show that the AlMg2 alloy structure are FCC system with lattice parameter (a) = 4.0817 A0.   Keywords: AlMg2 alloy, neutron diffraction, and FCC

Abstract

Abstract The purpose of this research is to analyze of tectonic earthquake parameter value in Bengkulu Province based on single-station data of BMKG Kepahyang, Bengkulu and multi-station data of BMKG Center, Jakarta along with determine its distribution model from January 2005 until March 2009. The results show that distance difference of mean earthquake epicenter is 28.60 km. The distribution of earthquake in Bengkulu Province from January 2005 until March 2009 had majority distributed in Hindia Oceanic and its mean earthquake included shallow earthquake (<70 km).   Keywords: Earthquake parameter, single-station, multi-station, magnitude, and epicenter.
