Abstract

The exposed sandstone unit in the research area located in the Kedungwringin area, Sempor District, Central Java Province is included in the Waturanda Formation. At the research location, there are 4 exposed rock units, namely Tuff Unit, Sandstone Unit, Breccia Unit, and Alluvial Unit. The sandstone unit in the study area has a type of Arkosic Wacke Sandstone. Measurable stratigraphic measurements were carried out on the three tracks and it was found that the research area was stratigraphically in the sandstone unit and the breccia unit in the south of the study area, and had a southwest-southeast current direction which was obtained based on measurements of sedimentary structures that developed in the study area.

Abstract

Energy is one of the essential needs in the household sector. Sukasari Village in Rumpin District is one of the areas in Bogor, West Java, where some residents still use kerosene or firewood for their daily household needs. Burning kerosene or firewood will produce carbon emissions and can damage the environment. There needs to be an alternative source of clean energy that is both environmentally friendly and economical. Many goat farming operations in the Rumpin area generate waste, which has the potential to be converted into biogas and used as a source of clean energy. Based on the survey, the goats' waste is only processed into fertilizer. A solution for providing clean energy sources while utilizing goat waste is to create useful products for everyday live through training and socialization in the construction of biogas digester. Based on the activities, residents can understand the solution to providing clean energy sources through using goat manure waste and are interested in using biogas from goat manure waste for their daily household needs.

Abstract

The city of Depok supports the capital city of Indonesia and experiences rapid population growth. As the population grows, the need for clean water becomes a significant concern in the area. According to data collected from 12 water samples in Cilodong District, Depok, all of them were found to be acidic and unsuitable for drinking. This community service initiative aims to provide the public with knowledge about techniques for building septic tanks that comply with regulations. Additionally, the public is educated on how to determine the characteristics of groundwater suitable for consumption. Counseling sessions were conducted at the Meruyung Village Office in Limo District, Depok City, and were attended by 26 Meruyung Village residents. The results of the program demonstrated an increase in public understanding of groundwater quality, rising from 74.5% to 89.5%.

Abstract

Geokimia migas merupakan ilmu untuk mengkorelasi keterdapatan suatu senyawa kimia dalam kegiatan eksplorasi cekungan berdasarkan karakteristik senyawa kimia dan sumber material organik. Komponen senyawa kimia seperti karbohidrat, protein dan lipid digunakan untuk mengamati perubahan material organik pada proses sedimentasi. Tumbuhan tingkat tinggi (higher plants) memiliki kelimpahan lignin yang merupakan komponen utama pada jaringan pendukungnya. Geologi regional daerah penelitian memiliki pola sesar naik yang terjadi pada back-arc basin. Konfigurasi Cekungan Jawa Barat utara dipengaruhi oleh block faulting dengan orientasi arah utara - selatan yang mempengaruhi pembentukan cekungan dan pola sedimentasi. Analisis kualitatif digunakan untuk menginterpretasikan karakteristik senyawa hidrokarbon batuan induk. Sampel cutting diekstraksi dan dianalisis dengan metode kromatografi. Keempat sampel yang berumur Oligosen Akhir – Miosen Tengah dengan interval kedalaman 950m - 950m, 2000 - 2005m, 2150m - 2152m, dan 2200m - 2202m didominasi oleh sterana karbon ganjil sehingga diinterpretasikan terendapkan di lingkungan darat dengan suplai material terrigenous dalam kondisi oksik. Sampel pertama dinyatakan jenuh, sampel ketiga dan keempat dinyatakan tidak jenuh berdasarkan persentase senyawa triterpana. Konfigurasi ikatan stereoisomer keempat sampel memiliki energi aktif yang berbeda sehubungan dengan keterdapatan senyawa hopana dan triterpana yang dapat menentukan sifat geometris hidrokarbon

Abstract

The Kutai Basin is a significant hydrocarbon potential basin with up to 15 km thickness of Tertiary sediments. It is dominated by a complex deltaic system to a marine shelf environment. Thus, it is crucial to understand the facies distribution in the area. This study was carried out to assess, correlate, and reconstruct the paleoceanographic evolution of the basin using lithological and microfossil data obtained from five exploration wells. The lithostratigraphic analysis was used to identify lithological units of each well, while the calcareous nannofossils biostratigraphy was applied to estimate the age and benthic foraminifera was analysed for paleoenvironmental interpretation. The findings reveal that the study region consisted of claystone, siltstone, shale, coal, and sandstone of the Gelingseh and Kelandasan Formation. The age of these lithological units is assigned from the Middle to Late Miocene epoch (NN6-NN11), based on the presence of some nannofossil index fossils such as Catinaster coalitus, Discoaster hamatus, Discoaster quinqueramus, Discoaster calcaris, and Coronocyclus nitescens. Benthic foraminifera assemblages are primarily composed of arenaceous species such as Trochamina spp. and Haplophragmoides spp., indicating a transitional environment, though some species such as Elphidium spp. and several planktonic foraminifera species appeared, which reflect marine influence on the research area. Based on the biofacies analysis; mudflats, tidal flats, delta front, prodelta-marine shelf, and fluvial plain were formed during the Middle to Late Miocene in the studied area.

Abstract

A functional hydrocarbon system relies on three key elements: source rock, reservoir rock, and seal rock. These components are essential in assessing the hydrocarbon potential of a region. In South Sulawesi, the Makassar Basin shows promise for petroleum development, particularly with the Mallawa Formation an Early to Late Eocene unit serving as a potential source rock. Source rocks play a critical role in generating and storing hydrocarbons. Indonesia’s frequent oil and gas exploration activities are driven by the presence of numerous prospective hydrocarbon-bearing areas. It's crucial to recognize that source rocks typically form within sedimentary basins. The Makassar Basin, a land-based Tertiary sedimentary basin situated along western and southern Sulawesi, originated from tectonic activity, specifically the widening of the Makassar Strait, which began no later than the Early Paleocene. This tectonic evolution significantly affected the thermal maturation of the basin’s source rocks. This study applies geochemical analysis of cutting samples to evaluate the maturity of these rocks. The findings contribute valuable understanding to hydrocarbon exploration in South Sulawesi, a region characterized by a complex tectonic framework. The results of laboratory analyses show that sustainable hydrocarbon exploration may be possible in South Sulawesi, especially in Balangbaru Formation, which is believed to be a potential source rock, in addition to the Mallawa Formation.

Abstract

Formasi Jatiluhur sering digunakan sebagai analogi reservoir untuk sistem minyak dan gas di Cekungan Jawa Barat Utara. Penelitian ini berfokus pada Formasi Jatiluhur, bagian dari batuan sedimen berumur Miosen Tengah yang tersingkap di bagian utara Cekungan Bogor, khususnya di wilayah Bogor dan Cianjur. Formasi ini berumur ekuivalen dengan Formasi Cibulakan yang terdapat di Cekungan Jawa Barat Utara. Tujuan utama penelitian adalah untuk mengidentifikasi litofasies dan sistem pengendapan Formasi Jatiluhur di sekitar Sungai Cikeruh, Sentul, Bogor. Metode yang digunakan meliputi observasi lapangan terhadap batuan sedimen, pengambilan 70 sampel untuk analisis laboratorium (mikropaleontologi dan sedimentologi), serta pencatatan litologi dan struktur sedimen. Hasil penelitian menunjukkan keberagaman litofasies, seperti batupasir dan batulempung, yang mencerminkan mekanisme pengendapan turbidit dalam lingkungan neritik luar hingga batial, dengan pola pengendapan yang berulang. Temuan ini diharapkan dapat memperkaya pemahaman mengenai sejarah geologi dan dinamika sedimentasi di wilayah Cekungan Bogor.
