Abstract

Foraminifera planktonik adalah salah satu proxy dalam penentukan iklim, termasuk iklim purba. Organisme ini memiliki sebaran geografi yang luas, dan beberapa spesies hidup pada kondisi iklim tertentu, sehingga keberadaan fosil ini sangat baik digunakan untuk interpretasi perubahan iklim dari masa ke masa. Formasi Tonasa memiliki sebaran yang luas di Sulawesi Selatan. Formasi ini disusun oleh batuan karbonat yang terbentuk dari mineral karbonat dan organisme laut diantaranya adalah foraminifera, yang dapat merekam kondisi iklim ketika batuan ini terendapkan. Pengambilan data singkapan menggunakan metode Stratigrafi Terukur pada perselingan napal dan batugamping di Barru (Lintasan Sungai Palakka) dan Jeneponto (Lintasan Karama B). Aktivitas selanjutnya adalah preparasi sampel, observasi, identifikasi dan determinasi umur berdasarkan pemunculan awal dan kemunculan akhir spesies. Hasil identifikasi foraminifera planktonik di daerah Barru diperoleh sebanyak 12 spesies: Globigerina senni, Globigerina ampliapertura, Globigerina soldadoensis, Globigerina yeguaensis, Globorotalia centralis, Globorotalia aragonensis, Globorotalia aspensis, Globorotalia bolivariana, Globigerina collactea, Hantkenina dumblei, dan Hantkenina brevispina, Globigerapsis index. Di Karama B sebanyak 6 (enam) spesies: Globigerina ampliapertura, Globigerina yeguaensis, Globorotalia kugleri, Catapsydrax dissimilis, Globorotalia siakensis, Globigerinoides immaturus, dan 1 sub-spesies Globorotalia opima opima. Analisis biostratigrafi Lintasan Sungai Palakka berumur P.9 – P.16 (Eosen Awal – Eosen Akhir), sedangkan Lintasan Karama B, berumur N.1 – N.7 (Oligosen Tengah – Miosen Awal). Hasil studi awal iklim purba menunjukkan bahwa beberapa genus/spesies di daerah Palakka dan Karama B hidup pada kondisi iklim Tropis – Subtropis, Sungai Palakka hangat (warm), sedangkan Karama B (cooling – warm). Berkurangnya variasi genus/spesies pada transisi umur Eosen ke Oligosen diakibatkan oleh perubahan iklim yang signifikan dari hangat ke dingin (cooling).

Abstract

The Walanae Formation has a wide distribution in the southern arm of Sulawesi, this rock formation was deposited during the formation of the basin due to the Walanae strike-slip fault. The Walanae Formation in the study area comprises sedimentary rocks and pyroclastic rocks, which give different soil characteristics. This study aims to determine the types of sandstones, rocks of origin, and provenance of sandstones in the study area by using spot sampling at representative stations and petrographic analysis. The sandstones of the study area are divided into two groups based on Folk (1974), namely arkose lithic and feldspathic litharenite. Based on the type of quartz, rock fragments, and associated minerals, the origin of the sandstones in the study area are plutonic igneous rocks, volcanic rocks, sedimentary rocks, and metamorphic rocks. The results show that the types of provenance sandstones in the study area are magmatic arc and recycled orogenic.

Abstract

The problem of clean water with high iron content significantly impacts the quality of life of people in Indonesia, including in Mangasa Village, Tamalate District, Makassar. Residents face reddish wells, tap water, and a metallic odor caused by geological factors or old and rusty pipes, which pollute water sources and endanger health. As a solution, Community Service activities by the Geological Engineering Department of Hasanuddin University socialize the use of limestone to reduce iron levels in water. This socialization results from a collaboration between the Community Service team and the capstone design team of geological engineering students at Hasanuddin University in designing clean water filters. The activity began with delivering educational materials regarding water quality problems and the benefits of limestone, accompanied by easy-to-understand visualizations. After a pre-test was conducted to measure initial understanding, the community service team presented and simulated limestone utilization, followed by an interactive question and answer session. Then, a post-test was conducted to evaluate the increase in participants' understanding, which was analyzed to measure the effectiveness of the socialization. The evaluation results showed a significant increase in participants' knowledge of clean water quality, the impact of iron content, and the use of limestone as a filter, which was 72%. This increase reflects the high enthusiasm and motivation of the community in adopting clean water treatment methods.

Abstract

This The Balikpapan Formation in the Lower Kutai Basin hosts a complex assemblage of fluvial-to-deltaic reservoir facies whose heterogeneity significantly influences reservoir quality and connectivity. This study integrates well-log interpretation, electrofacies classification, and quantitative petrophysical evaluation from six wells to assess the stratigraphic controls governing reservoir distribution. Three main facies associations are identified: channelised sandstones, mouth-bar to delta-front, and prodelta. Proximal channel sands exhibit the highest porosity (18–30%) and permeability (5–40 mD), but their limited lateral continuity results in poor interwell connectivity. Mouth-bar and delta-front sands display moderate porosity (12–25%) and permeability (<1–30 mD) and form laterally extensive, sheet-like bodies that enhance reservoir connectivity under increasing tidal influence. Thick prodelta mudstones act as regionally extensive vertical seals. The stratigraphic framework is characterised by repeated upward- coarsening parasequences bounded by marine flooding surfaces, reflecting alternating phases of delta progradation and transgression. These results demonstrate that depositional processes and stratigraphic architecture are the primary controls on reservoir heterogeneity in the Lower Kutai Basin.
