Abstract

Penelitian mengenai identifikasi sesar di Kabupaten Sumbawa bagian selatan ini dilakukan dengan menggunakan metode gravitasi. Penelitian Data yang digunakan berupa data Free Air Anomaly (FAA) dan Topografi yang merupakan data citra saletit TOPEX. Data tersebut dilakukan koreksi Bouguer dan Terrain untuk diperoleh data anomali bouguer lengkap. Nilai Anomali bouguer lengkap dilakukan pemisahan anomali regional dan anomali residual dengan menggunakan filter Gaussian. Anomali regional memiliki rentang nilai 115.0 mGal sampai 164.2 mGal sedangkan anomali residual memiliki rentang nilai -8.8 mGal sampai dengan 6.8 mGal. Pada Anomali residual menunjukkan zona anomali rendah pada zona selatan bagian tengah yang dipengaruhi oleh densitas batuan di zona tersebut yang berupa alluvial dan endapan pantai. Anomali residual yang dihasilkan dilakukan analisis second vertical derivative (SVD) untuk mengidentifikasi jenis sesar/patahan di wilayah tersebut. Berdasarkan interpretasi, zona sesar/patahan berada pada nilai anomali rendah yang diapit oleh nilai anomali tinggi sehingga patahan yang berada di bagian selatan daerah penelitian relatif berarah Timurlaut-Baratdaya. Grafik hasil slicing menunjukkan nilai maksimum lebih kecil dibandingkan mutlak nilai minimum sehingga disimpulkan bahwa sesar di kawasan tersebut merupakan sesar naik.

Abstract

A daisiac rock with the presence of abundant corderite and garnet that is considered quite unusual and named ambonite after its island name (Verbeek, 1905 in Pownall, 2013). Dacite rocks are scattered on Ambon Island and its surroundings. The Research Area is located in Hila Village, Central Maluku Regency located on Ambon Island. This study aims to determine the characteristics of petrogenesis of dasite rocks and their tectonic order. The methods used are studio analysis, geomorphological analysis, and geological structure analysis and laboratory analysis methods in the form of petrographic analysis, and XRF (X-Ray Fluoresence) analysis. Dacite rocks have porphyritic, intersetal, poikilitic, and reaction rim mineral textures. It also has a plagioclate microtexture in the form of coarse sieve, oscillatory zoning, rounded zone corners and glomerocrysts. Geochemically, this rock has an affinity  for alkaline calc  magma because it has a moderate K2O content and a fairly high SiO2 content. Ambonite rocks undergo magma differentiation in the form of fractional crystallization as seen from the harker diagram of the main oxide element. Based on its magma affinity of calc alkaline and its TiO2 content of less than 1%, it is indicated that ambonite rocks were formed in the archipelago. This order is assumed to have formed as a result of convergent interactions during the late Miocene.

Abstract

Urban Heat Island (UHI) is a phenomenon of increasing temperature in urban areas influenced by reduced vegetation and increasing surface temperature. This study aims to analyze vegetation distribution, land surface temperature, and UHI intensity in Sirimau District using Landsat imagery from 2019 and 2022. The analysis was conducted using the Normalized Difference Vegetation Index (NDVI), Land Surface Temperature (LST), and Urban Heat Island (UHI) parameters. The results showed that NDVI values in 2019 ranged from −0.0127 to 0.8531, while in 2022 they ranged from −0.017 to 0.8309. Low NDVI values were generally found in the urban center, whereas high NDVI values were identified in areas with dense vegetation. LST values in 2019 ranged from 18.524 °C to 28.546 °C, while in 2022 they ranged from 15.359 °C to 25.382 °C. Higher surface temperatures were concentrated in urban and settlement areas, while lower temperatures were found in vegetated areas. UHI values in 2019 ranged from −1.946 °C to 2.555 °C, while in 2022 they ranged from −2.489 °C to 2.942 °C. The study indicates an inverse relationship between NDVI, LST, and UHI, where areas with low vegetation density tend to have higher surface temperatures and stronger UHI intensity compared to vegetated areas. These findings highlight the important role of vegetation in reducing surface temperature and mitigating UHI effects. The results of this study are expected to support sustainable urban planning, the development of green open spaces, and climate adaptation strategies in Sirimau District.

Abstract

With the advancement of technology in the earth sciences, the identification, investigation, and interpretation of subsurface conditions to identify natural resources beneath the surface has become easier. Geophysical technology is a powerful method to support this process. Using currently popular geophysical methods, this is not difficult to accomplish. The geomagnetic method, in particular, is a well-established geophysical method in the exploration world. This method is highly sensitive to vertical changes in the subsurface, making it highly suitable for application, particularly in geophysical fieldwork, to identify hot springs. It is hoped that students, the community service team, the community, and the Tulehu regional government will experience the positive impact of this program. As is known, the Tulehu region boasts abundant natural resources, yet they remain largely unexplored. Therefore, through the implementation of geophysical fieldwork as a community service activity, these manifestations can be properly investigated. In fact, with the application of geophysical applications, hot springs have been identified at several locations. This location has become iconic in education (geological-geophysical studies) and for tourism (geotourism) as a learning reference. In the future, the community service team hopes to continue developing other activities and innovations using a geophysical approach so that they can have a positive impact on various general audiences.

Abstract

The Kuta region is one of the most developed tourism areas in the Central Lombok Regency. This development impacts the population that continues to increase in the area, thereby influencing the increasing need for groundwater. However, the study area tends to be dry, especially in the dry season and rainfall is very low. This is quite difficult for residents to find good aquifers for groundwater exploration. From this, subsurface lithology identification is carried out to determine the lithology of the subsurface layers to obtain potential aquifers. The method used is geoelectric vertical electrical sounding which is carried out at two location points with a track length of 500 meters and a spacing of 10 meters. From the analysis of the 1D resistivity curve produced in this survey, information on subsurface lithology at the measurement point, consisting of layers of clay, sandstone, and breccia, was obtained. At the MR-1 line there is sandstone lithology at a depth of 53-84.3 meters which is thought to have the potential to be an aquifer, while at the MR-2 line, the presence of sandstone lithology is at a depth of 67.5-110 meters. Therefore, this measurement location shows the prospect of the existence of an aquifer which is characterized by a layer of sandstone which is a rock with good porosity and permeability

Abstract

Telah dilakukan penilitian di Lapangan “Aru” yang merupakan lapangan migas di Cekungan Jawa Barat Utara. Penggunaan data konvensional untuk identifikasi potensi reservoar batupasir dan sebarannya di daerah penelitian masih kurang optimal sehingga analisa dilakukan menggunakan atribut RMS Amplitude. Penelitian bertujuan untuk mengidentifikasi sebaran reservoar batupasir yang berpotensi sebagai penyimpan hidrokarbon di daerah penelitian. Data yang digunakan adalah data seismik dan data sumur. Data seismik berupa data sekunder 3D pre-stack time migration (PSTM) yang terdiri atas 381 lintasan inline dan 859 crossline dengan sampling rate 2 ms. Digunakan pula empat data sumur yang dilengkapi properti fisik dan marker reservoar kajian. Pengolahan datanya diawali dengan pembuatan sintetik seismogram untuk menyamakan horizon seismik dalam skala waktu dari data seismik terhadap posisi kedalaman sebenarnya pada data sumur. Pembuatan time structure map untuk analisa struktur tinggian dan rendahan sebagai potensi jebakan hidrokarbon. Tahap akhir pengolahan yaitu analisa sebaran reservoar batupasir yang berpotensi menyimpan hidrokarbon melalui peta anomali atribut RMS amplitude. Hasil interpretasi time structure map dari penampang reservoar 39A dan 39C secara struktural menunjukkan sumur B1 dan A4 terletak pada area tinggian dengan nilai surface elevation yaitu -1175ms sampai -1025ms. Hasil ini dikorelasi dengan peta anomali atribut RMS amplitude dari penampang reservoar 39A dan 39C namun ditunjukkan bahwa hanya area sumur B1 yang memiliki kontras yang ekstrim terhadap anomali amplitudo tinggi dengan nilai -103 hingga -303 yang penyebarannya hingga ke arah Utara. Kontras anomali amplitudo tinggi ditafsirkan sebagai litologi batupasir terisi hidrokarbon. Hasil ini berkorelasi juga dengan well test sumur B1 yang terbukti mengandung hidrokarbon.

Abstract

Ambon City, located in the Maluku Province, is experiencing rapid development. This rapid development has resulted in an increasing number of areas that should absorb water being covered by roads and buildings, leading to a decrease in water absorption into the ground and frequent flooding in several areas around the coast. This is due to the drastic increase in rainwater volume, which exceeds the capacity of drainage channels (culverts) and ultimately leads to flooding in rivers. Identifying flood-prone areas is crucial for estimating the potential impact of flooding. The results can be one of the flood mitigation efforts in the area. Geographic Information Systems (GIS) can be a solution for obtaining information on identifying and predicting flood-prone areas by creating, transforming, and analyzing field observation data into maps that show flood-prone areas. In this study, various factors and variables were collected and adjusted with specific considerations drawn from multiple references and reference materials to identify and predict flood vulnerability in the area. The analysis indicates that 5.98% of the coastal area in Teluk Ambon Baguala District has a very high vulnerability to flooding, while 58.89% of the coastal area is characterized by a high level of vulnerability to flooding.
