Abstract

Telah dilakukan penelitian pengukuran medan gravitasi untuk mengetahui pola sebaran anomali Bouguer dan mengidentifikasi struktur geologi di daerah selatan Pulau Buton. Pengukuran data medan gravitasi menggunakan satelit Global Gravity Model plus (GGMplus) dengan spasi antar titik pengukuran ~220 meter. Data yang digunakan berupa data medan gravitasi yang telah terkoreksi udara bebas, sehingga hanya perlu melakukan koreksi Bouguer dan koreksi medan untuk memperoleh anomali Bouguer lengkap di topografi. Selanjutnya dilakukan proyeksi ke bidang datar, kontinuasi ke atas, dan analisis Second Vertical Derivative (SVD). Hasil anomali Bouguer lengkap dan anomali lokal menunjukkan pola sebaran berarah timurlaut-baratdaya. anomali tinggi berada di bagian timurlaut dan baratdaya daerah penelitian sedangkan anomali rendah berada di bagian selatan, timur dan kawasan utara-baratdaya daerah penelitian. Anomali tinggi diduga disebabkan oleh keterdapatan potensi hidrokarbon berupa bitumen aspal yang berasosiasi dengan Formasi Tondo dan Formasi Sampolakosa. Anomali rendah di kawasan selatan disebabkan karena daerah tersebut didominasi oleh batuan yang berumur sangat muda (Formasi Wapulaka), sedangkan anomali rendah di kawasan utara-baratdaya mengindikasikan daerah cekungan yang berada di Selat Buton. Berdasarkan hasil analisis SVD pada anomali lokal, terdapat 10 sesar yang bisa diidentifikasi jenis sesarnya. Sesar A,B,E,G,H, dan I diidentifikasikan sebagai sesar turun, sedangkan sesar C,D,F, dan J diidentifikasikan sebagai sesar naik.

Abstract

Island of Buton is a region located in the Southeast Sulawesi region, Indonesia. The formation of Buton Island is the result of intense tectonic processes, resulting in diverse geological resources, including natural resources such as oil and natural gas accumulated in a sedimentary basin. Gravity field measurements have been conducted to interpret subsurface structures in the Muna-Buton Basin. The data used consist of free air gravity anomaly data, requiring corrections for Bouguer and terrain to obtain a complete Bouguer anomaly. Anomaly separation is performed using trend surface analysis method. Gradient analysis is conducted on residual anomalies to delineate basin structures in the research area using several methods, including horizontal gradient, total gradient, tilt-angle horizontal gradient, and improved logistic filter. Qualitatively, two sub-basins can be delineated: Sub-basin A is in the east and sub-basin B is in the west. Sub-basin A is estimated to be the Bulu sub-basin, while sub-basin B is the Buton Strait sub-basin. Based on subsurface modeling results, there is a basement layer indicated to be at an estimated shallowest depth of 2 km in the Buton Strait sub-basin and an estimated shallowest depth of 3 km in the Bulu Basin sub-basin. The depth of this basement layer increases towards the center of the basin, reaching more than 4 km.

Abstract

The management of Islamic education learning based on digital technology, adapts to Islamic values, recognizing that religious education cannot rely solely on digital tools. Therefore, teachers still play a guiding role in providing direct support to students. This research aims to analyze the management of digital technology use in Islamic Religious Education (PAI) Total Quality Management Perspective. The findings indicate that character-based PAI learning through digital technology encompasses four key elements: digital teaching modules and Learning Management Systems (LMS), digital technology-based learning infrastructure, teacher training, and support for character development in students. These four elements are accompanied by total quality management, so that PAI learning using digital technology accelerates the achievement of educational goals. This research is qualitative, descriptive, and analytical, utilizing a phenomenological approach. Primary data for this research was obtained directly from the Islamic Development Network (IDN) in Bogor.
