Abstract

Telah dilakukan pengukuran gayaberat di daerah Lombok Tengah dan Lombok Timur yaitu dari Jonggat hingga Pringgabaya. Penelitian ini bertujuan untuk mengetahui ketebalan sedimen daerah Lombok Tengah dan Lombok Timur dengan menggunakan analisis spektrum pada data gayaberat. Dalam penelitian ini analisis spektrum dilakukan dengan cara mengubah data dari domain ruang ke dalam domain bilangan gelombang. Pada peta kontur complete bouguer anomaly daerah penelitian dibuat dua macam slicing yaitu slicing horizontal dari arah barat hingga timur daerah penelitian dan slicing vertikal dari arah utara hingga selatan daerah penelitian. Dari slicing arah horizontal didapatkan rata-rata ketebalan residual yang merepresentasikan ketebalan sedimen dari arah utara hingga selatan daerah penelitian sebesar (2154,47±1231,83) meter, sedangkan dari slicing arah vertikal didapatkan rata-rata ketebalan residual yang merepresentasikan ketebalan sedimen dari arah barat hingga timur  daerah penelitian (790,73±260,53) meter. Dari nilai ketebalan sedimen yang didapatkan menandakan daerah Lombok Tengah dan Lombok Timur memiliki tingkat keamanan dan ketahanan bangunan terhadap gempabumi lebih besar dibandingkan dengan daerah Lombok bagian utara. Hal ini dapat dilihat dari setelah terjadi gempabumi, kerusakan di daerah Lombok Tengah dan Lombok Timur lebih ringan dibandingkan dengan daerah Lombok bagian utara.

Abstract

One of the impacts of waste management is the presence of side-residual landfill waste that causes pollution potential of pollutants results in the form of decaying garbage leachate. This contamination occurs around the landfill Kebon Kongok impacting environmental degradation around the landfill area. To determine the extent to which and how the subsurface conditions around the landfill Kebon Kongok it will do the mapping and modeling using 3-dimensional (3D) geoelectrical method. The study was conducted on 3 pieces of lines are trending relative Southwest-Northeast. Each track has a length of 150m and retrieval of data using a dipole – dipole configuration-with spacing of 10m length. Resistivity measurements carried out with resistivitimeter GL-4100 GSound type and processed with software Res3Dinv. From the analysis it can be concluded that the entire study area has been contaminated by leachate polution, especially in the surface layer to a depth of 13.9 meters.

Abstract

Studies have been conducted to identify the occurrence of subsidence, a decline of groundwater, and to model the causes of subsidence in areas of Jakarta based on response of microgravity anomaly and vertical gravity gradient over time. Based on the processing and interpretation of gravity data advance of the time concluded that by using a combination of time lapse microgravity and its vertical gradient have been able to localize the source of the gravity anomaly and the results are strongly support the results of filtering to separate the source of the anomaly. The subsidence that occurs predominantly due to resettlement (in West and North Jakarta), caused by the extraction of groundwater and resettlement (in Central and East Jakarta), and dominated due to the extraction of groundwater (in South Jakarta).Keywords : Groundwater, time lapse micogravity, time lapse vertical gradient, resettlement, subsidence

Abstract

Based on the BMKG report on Wednesday, July 29, 2018, at 05.47 WIB, an earthquake with a magnitude of 6.4 SR occurred at the epicenter at a depth of 24 km and was 47 km northeast of the island of Lombok. They are allegedly originating from the Back Arc Thrust Flores, the interaction between the Indo-Australian Plate and the Eurasian plate. This study aims to analyze the subsurface structure of the island of Sumbawa and Flores sea based on the distribution of density values. The analysis was carried out by modeling the subsurface structure based on regional gravity field anomaly data. The data used is secondary data downloaded from the topex.ucsd.edu page 18,400 measuring points. Data processing consists of data correction, separation of anomalies, determination of the Second Vertical Derivative (SVD) value, and 3D and 2D inversion modeling. The data corrections performed are Bouguer correction and terrain correction to produce the total gravity anomaly value. Upward continuation is used to separate regional anomalies and residual anomalies. Analysis of the Second Vertical Derivative (SVD) value was carried out to identify rock contact positions and fault structures. The 3D inversion modeling is done by making a mesh model, and to get a 2D cross-section, six slices are used in the 3D model. The results of the 3D model and 2D cross-section, namely the island of Sumbawa to the Back Arc Thrust zone of Flores, consists of 3 main layers comprised of the upper crust with a density of 2.29 gr/cc - 2.63 gr/cc, the middle crust with a density of 2.64 gr/cc - 2.90 gr/cc, and the lower crust with a density of 2.91 gr/cc - 3.14 gr/cc, and based on the model and SVD value, it shows that the Flores back fault, the reverse fault type, starts at a depth of ± 26 km
