The ground motion intensity caused by an M 6.3 earthquake that struck Mentawai Strait on September 1st, 2017 with epicenter -1.24 N and 99.75 E and depth 58 km were recorded on BMKG’s seismic and intensity network, the intensity was about III - IV intensity scale (MMI) and the acceleration was 2.8 g. The earthquake intensity calculation in Indonesia can also be calculate by using Ground Motion Prediction Equation (GMPE) such as Si and Midorikawa (1999), Mc Guire (1963), Donovan (1973) and Wu et al (2003) empirical equations. We conducted a research to compare the peak ground acceleration calculation between using empirical equation and by using data observed on BMKG’s intensity networks. The PGA result on every district of Sumatera Barat Province that shown on BMKG’s shakemap has a significant different comparing with the calculation using the equations. The PGA values by using the empirial equations were decayed through the hipocenter distance of the earthquake in every district of Sumatera Barat Province. Meanwhile base on the observed one, we found some anomalies of PGA value on some BMKG’s accelerograph station networks i.e. PDSI in Padang and PAPA in Padang Panjang with 14.35 g and 5.07 g respectively. But these anomalies were not impacted to the result of the intensity, because they have some filters that can elimunate these kind of anomalies to conduct an accurate result.

Publisher : Universitas Sebelas Maret

Mapping of rock resistivity value is useful for knowing the potential of the natural wealth contained in the earth. Investigation of resistivity value in Solok Regency is using 3 lines. The first line is at S 00055'0.7 "and E 100040'56.8" coordinates, the second line is located at S 00054'53.2 "and E 100041'00.9" coordinates, and the third line is coordinated by S 00055'20.5 "and E 100041'01.8". The method of mapping is using the Geoelectric method with Schlumberger Configuration and the Ares (Apparent Resistivity) tool. The data obtained is processed by using Res2Dinv software to be analyzed and interpreted. The results obtained on the first line have resistivity value of 3.95-641 Ωm which is interpreted by having a rock structure consisting of Groundwater, Clay, Dry Clay, Basalt and Andesite. Next on the second line, the resistivity values of 2.53-1560.5 Ωm are obtained consisting of layers of rock Groundwater, Clay, Dry Clay, Basalt, and Andesite. Finally on the third line have resistivity value about 6.85-113.5 Ωm having a Groundwater, Tuff, Sandstone, Clay, Dry Clay, Basalt, Andesite, and Lava rock structure. The Tuff rock layer is estimated as a geothermal reservoir because its resistivity value is 20.8-23.6 Ωm surrounded by more contrasting rock layers and is located between two solid rock layers.

Clay in West Sumatra has been developed as an industrial material, one of which is a natural dye for batik. The use of clay as a natural dye was previously known to have magnetic minerals contained in clay so as to produce color and resistance to fabrics. Currently, no one has investigated the types of magnetic minerals found in clay and their effect on color resistance in batik cloth, so this study aims to determine the types of magnetic minerals in clay and their effect on color resistance in batik cloth. Clay samples were taken from two areas in West Sumatra, namely Pesisir Selatan and Sijunjung. Samples were characterized from the extraction of clay using X-Ray Diffraction, where measurements were taken before and after the dyeing process on the fabric. The results showed that the types of magnetic minerals found in the clay before and after dyeing the fabric were Maghemite. In addition, the non-magnetic mineral found in clay is Quartz. The color resistance test on the CL-SPPS-210314-2 fabric sample did not change color, on the contrary, the CL-PSBSJJ-210421 fabric sample experienced quite a change from the original color of the fabric or before washing.

Clay in West Sumatra has been used as a natural dye for batik, so the batik is known as clay batik. The dyeing of the cloth is done by boiling and soaking the clay together with the cloth for 10 days. The color of the fabric is caused by certain elements present in the clay. Currently, no one has investigated the changes in elemental content due to the dyeing process. This research aims to investigate the changes in the concentration of the elements that affect the color of the fabric. Samples were taken from 4 areas, namely Solok, Sijunjung, Lima Puluh Kota, and Pesisir Selatan with a total of 8 samples, of which 4 samples were measured before the staining process and 4 more samples after the staining process. Changes in the elemental content of clay were investigated using X-Ray Fluorescence (XRF). The results of the study showed changes in the content of the dominant element, namely Al, Si, and Fe contained in samples CL-PYKLN 2A and CL-TJG GDG 210422. While the samples CL-PSB-SJJ 210421 and CL-SPPS 1 210314 the change in the concentration of the elemental content was not too significant. The elements that cause colored cloth are all elements in clay, but the dominant element in coloring cloth is Fe.

Sungai Limau is one of the sub-districts in Padang Pariaman Regency which was badly damaged by the earthquake on 30 September 2009. Geologically, the Sungai Limau area is included in the category of cambisol soil types in the form of layers of sand, making it vulnerable to liquefaction due to earthquakes. This research was conducted to analyze the liquefaction potential using the Multichannel Analysis of Surface Wave (MASW) method. The MASW method can produce 2D Vs profiles to describe the structure and types of rock-forming materials at each depth and layer. This method can detect underground surfaces Vs to a depth of 30 meters. Data collection was conducted at Sungai Limau using the sysmatrack-MAE tool with 4 observation tracks. Each measurement uses a distance between geophones of 4 meters. The Vs results from MASW will be compared with the classification of soil types from UBC 1997. The average results of the shear wave velocity at a depth of 30 m (Vs30) in this study are 322.9 m/s for the first track, 303 m/s for the second track, 311 m /s for the third and fourth track. The four tracks fall into the same classification, namely medium soil type (class D). The results of the liquefaction potential analysis using the MASW method show that the first line has a high level of liquefaction potential in the third layer with a value of Vs 337 m/s (class D). The second track has a high level of liquefaction potential in the third layer with a value of Vs 314 m/s (class D). The third track has a fairly high level of liquefaction potential in the second layer with a value of Vs 209 m/s (class D). The fourth track has a high level of liquefaction potential in the second layer with a value of Vs 198 m/s (class D). The fourth and fifth layers on the entire track have no liquefaction potential with Vs ranging from 400-550 m/s (Class C).
