Northern part of Masalima Trench Basin is located in the southern part of the Strait of Makassar, which includes Masalima Trough and Massalima High. The area of research is an extension of the South Makassar Basin which extends from South Makassar Basin to the Northeast part of Java Sea. Subsurface data are used such as 2D seismic sections (21 lines) and data drilling wells (2 wells) to understand the tectonic structure in the basin formation and understand the stratigraphic order of basin. Based on well data can be known that Northern part Masalima Trench Basin is aborted rift because marked by post rift phase. Northern part Masalima Trench Basin was formed by normal faults which have trend northeast-southwest with  pre rift, early syn rift, late syn rift, and post rift sediment geometry. Early syn rift sediment was Middle Eocene, late syn rift sediment was Middle Eocene till Early Oligocene and post rift sediment was Early Oligocene till Early Miocene. The Depositional environment of early syn rift phase such as beach, shallow marine, and land. The Depositional environment of late syn rift phase such as beach till deep marine, and the depositional environment of post rift is deep marine.

Groundwater research for drinking purpose was very important to be done at ITERA campus and its surroundings. It is caused the area is very close to social activities, especially for students. The hydrogeochemical analysis was done with integrating Piper diagram plotting result, X-Y plotting result for some cations and anions, and Gibbs diagram plotting result. Groundwater assessment for drinking purpose referred to Peraturan Menteri Kesehatan Republik Indonesia No. 492/MENKES/PER/IV/2010. There were 14 samples that were taken from nine dig wells and five drill wells. The groundwater facieses were dominated by Facies Na-HCO3-Cl (35,71%) followed by Facies Na-Cl (21,43%), Facies Na-HCO3 (21,43%), Facies Na-SO4-Cl (14,29%), dan Facies Ca-Mg-HCO3 (7,14%). Generally, Groundwater hydrogeochemical of research area shows that groundwater chemistries are controlled by minerals weathering, evaporation, and precipitation. There are eight wells that not proper for drinking and six wells that proper for drinking. Integration lab result, stratigraphic analysis, and depth aquifer show that groundwater that proper for drinking comes from confined aquifer while that not proper for drinking comes from unconfined aquifer

Way Huwi Village is located in South Lampung, near the Institut Teknologi Sumatera (ITERA). The purposes of this research is to know the unconfined groundwater flow pattern and groundwater facies changes. We measured the depth of water table at nine dig wells, analyzed piper diagram for groundwater facies identification. Then, we integrated groundwater flow patterns and groundwater facies from each well to analyze groundwater facies change pattern in research area. The result indicated that the unconfined groundwater flows from SW to NE of research area, following higher (SW) to lower elevation (NE). There are six patterns of unconfined groundwater facies changes: from Facies Na-Cl to Facies Na-HCO3-Cl, Facies Na-HCO3-Cl to Facies Ca-Mg-HCO3, Facies Na-HCO3-Cl to Facies Na-Cl, Facies Na-HCO3-Cl to Facies Na-SO4-Cl, Facies Ca-Mg-HCO3 to Facies Na-SO4-Cl, and Facies Ca-Mg-HCO3 to Facies Na-HCO3-Cl. ABSTRAK - Pola aliran airtanah tidak tertekan dan perubahan fasiesnya di Desa Way Huwi, Lampung Selatan. Desa Way Huwi terletak di Lampung Selatan, di dekat Institut Teknologi Sumatera (ITERA). Tujuan dari penelitian ini adalah untuk mengetahui perubahan pola aliran airtanah dan fasies airtanah yang terjadi. Kami mengukur kedalaman muka airtanah pada sembilan sumur gali, menganalisis Diagram Piper untuk mengetahui fasies airtanah. Kemudian kami mengintegrasikan pola aliran airtanah dan fasies airtanah setiap sumur untuk mengetahui pola perubahan fasies air tanah. Hasil analisa menunjukkan bahwa airtanah tidak tertekan mengalir dari Barat Daya ke Timur Laut mengikuti ketinggian yang lebih tinggi (SW) ke ketinggian yang lebih rendah (NE). Ada enam pola perubahan fasies airtanah tidak tertekan: dari Facies Na-Cl ke Facies Na-HCO3-Cl, Facies Na-HCO3-Cl ke Facies Ca-Mg-HCO3, Facies Na-HCO3-Cl ke Facies Na-Cl, Facies Na -HCO3-Cl ke Facies Na-SO4-Cl, Facies Ca-Mg-HCO3 ke Facies Na-SO4-Cl, dan Facies Ca-Mg-HCO3 ke Facies Na-HCO3-Cl

The Age majority of regional geological maps that have been referenced by geologists in Indonesia are about 20-30 years old. One of them is Tanjung Karang Geological Map. Our opinion is that the map is old enough. Some faults features are doubted in the aspect of existence and its trend. It is represented by the dashed line symbol in the maps. Therefore, this research was carried out to provide a more detailed reinterpretation of faults in the Way Huwi area using the Gravity method. This area was selected because it is the new education center and economy in the eastern part of Bandar Lampung. This research was also carried out as part of disaster mitigation. The faults within this research area were identified with Horst-Graben type and formed before Lampung Formation was deposited. The trend of these normal faults is Northeast-Southwest. it is very different from the fault interpretation on Tanjung Karang regional geology map with the Northwest-Southeast direction. The genesis of the Way Huwi Fault is indirectly part of the extensional Sunda Strait.

Bandar Lampung merupakan salah satu kota besar di Indonesia. Kebutuhan air bersih Bandar Lampung meningkat seiring dengan bertambahnya jumlah penduduk dan kegiatan industri. Suplai air yang dilakukan oleh PDAM Way Rilau hanya dapat melayani 32% dari total penduduk Bandar Lampung. Hal ini mengindikasikan bahwa sebagian besar penduduk Bandar Lampung mengambil air tanah untuk memenuhi kebutuhan air sehari-hari. Penelitian ini dilakukan untuk mengetahui kondisi air tanah di CAT Bandar Lampung, baik kuantitas maupun kualitas. Jumlah sampel yang digunakan yaitu sebanyak 15 sampel. Berdasarkan hasil analisis kimia air tanah yang diplotkan dalam diagram piper, diketahui bahwa fasies hidrogeokimia pada daerah penelitian terdiri dari dua jenis yaitu berjenis natrium bikarbonat dan magnesium bikarbonat. Tipe air bikarbonat mengindikasikan air tanah berasal dari air tanah yang dangkal. Sedangkan kation berupa magnesium dan natrium mengindikasikan air tanah tersebut mengalir melalui jenis batuan yang berbeda. Kandungan nitrat hasil analisis memiliki nilai maksimal sebesar 0,85 mg/L, sedangkan nilai minimal sebesar 0,24 mg/L, dan nilai rata-rata sebesar 0,6 mg/L. Berdasarkan nilai kandungan nitrat tersebut, air tanah pada sample yang diambil berada di bawah nilai baku mutu mengacu pada Permenkes No. 492/MENKES/PER/IV/2010 sebesar 50 mg/L.

Locating geodiversity hotspots across large areas poses a challenge for further geopark development in Indonesia, especially on Lombok Island, which spans 5,435 km². A geodiversity hotspot is an area rich in unique geological features that need to be determined. Therefore, this study's objective is to track and assess the potential of geodiversity on Lombok Island. The methods employed a grid-based spatial indexing method to pinpoint potential geodiversity hotspots in Lombok. The entire island was covered using 238 grids of 5×5 km² for this study. The technique applied these equal weight parameters: relative drainage density (20%), diversity of topographical slope (20%), elevation (20%), diversity of geological formation (20%), and soil characteristics (20%). The identified geodiversity hotspots were validated through ground checking. The results show significant geodiversity hotspots: Gangga (116°12'13.122"E;8°21'24.154"S), Sikur (116°24'32.015"E;8°29'23.597"S), Bayan (116°32'33.211"E;8°16'22.39"S), Sembalun (116°29'18.063"E;8°23'22.156"S), Sambelia (116°35'40.856"E;8°24'1.371"S), and Gerung-Kuripan (116°8'20.085"E;8°41'46.513"S). These hotspots showcase a range of lithologies from the Oligo-Miocene to the Plio-Pleistocene, along with terrestrial and marine fossils, minerals, geothermal activities associated with the Rinjani Volcano, and diverse soil types that support rich biodiversity. The dense drainage systems in these regions create stunning waterfalls and distinct elevational ecosystems. Tourism is primarily concentrated in well-known sites like Sembalun and Gerung-Kuripan, while lesser-known areas such as Sambelia, Gangga, Sikur, and Bayan remain underexplored. The natural drainage systems in these hotspots play a crucial role in hydrology and contribute to the beautiful landscapes. This study concludes that Lombok Island has six significant geodiversity hotspots, which hold geological importance for supporting the geoheritage of the Rinjani-Lombok UNESCO Global Geopark. The findings contribute to promoting local development by integrating cultural aspects and ensuring sustainability in line with global sustainable development goals. Additionally, the study provides new insights into the geotourism potential that can support sustainable development within the Rinjani-Lombok UNESCO Global Geopark.
