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

DOI:10.17014/ijog.9.3.303-314The eastern part of the Makassar Strait has not achieved significant success in the petroleum exploration stage. In general, exploration wells in this area have not found hydrocarbons to date. Most of the problems experienced by these wells are geochemical-related, including the absence of a source rock where the hydrocarbon is formed, immature source rock, and low volume of hydrocarbon. Therefore, this study aims to find potential Eocene source rock in West Sulawesi. It commenced by determining the paleofacies followed by the geochemical analysis of well cutting and surface samples. The geochemical analyses conducted are total organic carbon (TOC), rock eval pyrolysis (REP), kerogen type, vitrinite reflectance (VR), and gas chromatography/mass spectrometry (GC/MS). The samples that have a potential as an Eocene source rock were coal, as well as carbonaceous and marine shale. Based on the plotting of relative abundance for sterane (C27 - C29), the coal and carbonaceous shale had the input from terrestrial organic material with a contribution from marine, while marine shale had the input from marine organic material and contribution from terrestrial. Furthermore, coal and carbonaceous shale had a relatively high proportion of C29 sterane compared to C27 and C28, while marine shale had a relatively high proportion of C27 compared to C28 and C29. The higher plants also contributed to the organic matter in carbonaceous shale and coal samples, as indicated by the abundance of oleanane/C 30 hopane and the other significant content of resin biomarker. In accordance with the objectives of the study, it was found that during the Eocene, the type of source rock in the eastern side of the province varied, starting with coal and carbonaceous shale in the upper intertidal-fluviodeltaic environment, and marine shale sediments from the source facies of marine algal.

Abstract

Cooking oil that is no longer utilized can be used as a basic ingredient in the production of soap bar, and other products that can be used in daily life, such as washing clothes or kitchen utensils. The remainder of cooking oil, also known as waste cooking oil, is typically poured down the drain, where it can plug the drain since the oil freezes at low temperatures, causing environmental pollution. Based on this issue, the FTKE Universitas Trisakti community service team taught inhabitants of 07 Area, Duri Pulo Sub-district, Jakarta how to make bar soap from waste cooking oil. However, waste cooking oil cannot be used directly as an ingredient for creating soap because of the color and aroma, therefore it must be cleaned first by adding activated carbon, namely charcoal as an adsorbent, into the waste cooking oil to absorb the color and aroma. Later on, mix the oil and lye (a combination of NaOH and water), stir until the mixture resembles liquid soap, and then add around 1 ml of fragrance. Put the mixture in the drain. Leave the soap in the mold for 24 hours until it solidifies and hardens, then remove from the mold. It is intended that with this training, locals would be able to better their economic standing by saving more money while simultaneously helping to save the environment.

Abstract

ABSTRACTNumerous oil and gas seeps occur at onshore West and South Sulawesi. These may indicate the presence of active petroleum system in subsurface hence the area is worthy for further exploration. No discovery well so far in this area. Therefore, the seeps provide significant data to build integrated petroleum system analysis.A number of geochemical analysis were conducted on the oil seeps and rock samples from outcrop and well cuttings to reveal the source rocks that generate the oils. Triterpane m/z 191 shows low content of tricyclic terpane, low norhopane to hopane, and abundant oleanane. Sterane m/z 217 and bicyclic alkane m/z 123 show dominant C29 sterane and bicadinane. These biomarkers indicate that the source of oils are coals and/or coaly shales deposited in fluvio-deltaic setting. Contribution from marine input is shown in Karama region to the south.Based on stratigraphic setting of West and South Sulawesi, the best candidate for the source of oil seeps is Eocene coals or coaly shales of Toraja or Kalumpang Formation. The Eocene coal samples have been characterized and show similar GC alkane distribution with the oil seeps. Contribution from marine facies, which may age-equivalent to these coals are shown in Karama region.Aromatic methyl phenanthrene m/z 178 and m/z 192 were also analyzed to know their maturities and they were generated at maturity level equivalent with Ro 0.8-1.0 %.Based on geochemical constraints and geologic data, a paleogeographic setting of Eocene Toraja/Kalumpang Formation was built to know better about the paleo-source facies of the oils and its geochemical characteristics. Keywords: Biomarker, coaly shales, Toraja/Kalumpang Formation

Abstract

The study area is located in the Offshore North West Java (ONWJ) Working Area, with research conducted on the AFR-1 well. Aims: to characterize the geochemical properties of source rocks and develop a 1D burial history model of the research area. The methodology: includes analysis of organic content through Total Organic Carbon (TOC), Rock-Eval pyrolysis, vitrinite reflectance, and heat flow measurements on samples. The primary source rock is identified within the Talang Akar Formation. Conclusion: The research results indicate that the source rock in Well AFR-1 has a TOC content ranging from 0.15% to 63.08%, with S1 and S2 values suggesting hydrocarbon generation potential. The hydrogen index (HI) and oxygen index (OI) reveal a dominance of Type II/III kerogen, indicating the ability to generate both oil and gas. Thermal maturity based on Tmax shows that the source rock has entered the oil and gas window. 1D basin modeling using geochemical data from Well AFR-1 demonstrates that the Talang Akar Formation, composed of shale, sandstone, and coal lithologies, can act as a source rock, with hydrocarbon expulsion in the Deltaic Talang Akar Formation beginning at 2.26 Ma (Pleistocene). This study provides deeper insights into the source rock potential and its implications for hydrocarbon exploration in the ONWJ (Offshore Northwest Java) working area.
