Abstract

Laboratory analysis has proven the Talang Akar Formation as a source rock that is relatively rich in organic content, but the availability of laboratory data is very limited to determine the quantity of organic material in a regional basin area, which is the main objective in this research. Therefore, a simple proven and accurate method is needed to model the TOC (organic carbon content) throughout the borehole is needed. TOC log modeling was performed using the Passey method, multilinear regression and neural network. Based on the modeling results, the multilinear regression method got better results to be applied to the Talang Akar Formation.

Abstract

Seiring berkembangnya teknologi dan industri di dunia memberikan beberapa dampak positif dan juga ada dampak negatif. Salah satu dari dampak negatif itu adalah meningkatnya kebutuhan akan energi listrik yang mengakibatkan meningkatnya penggunaan bahan bakar fosil. Penggunaan bahan bakar fosil dapat berdampak pada lingkungan. Oleh karena itu pengembangan sumber daya alternatif seperti MFC (Microbial Fuel Cell) ini sangat di butuhkan demi mengurangi konsumsi bahan bakar fosil. MFC adalah bioreaktor yang mengubah energi kimia senyawa menjadi energi listrik melalui reaksi katalitik mikroorganisme dalam keadaan anaerob. Berdasarkan beberapa penelitian, banyak bakteri yang memiliki potensi besar untuk menghasilkan listrik dengan menggunakan metode ini.Penelitian ini bertujuan untuk mengkaji jenis bakteri pada larutanEM4 terhadap  Cr(VI),pengaruh jenis dan konsentrasi bakteri yang digunakan pada produksi bio-listrik. Penelitian dilakukan dalam skala laboratorium. Hasil yang diperoleh dianalisa dengan multimeter agar diketahui power density dan spektrofotometer Uv-vis untuk identifikasi logam Cr(VI) yang tereduksi menjadi logam Cr(III).

Abstract

The boiler is in charge of generating steam. The steam produced can be used for several purposes, among others: as a working fluid to drive steam engines such as turbine engines and compressor piston engines, as a heating medium for heating liquids so that they are always at a set temperature, as an auxiliary medium for processing and so on. . In the context of energy conservation today, energy use is very much taken into account, because energy consumption is closely related to operating costs. In principle, the more energy consumed means higher operating costs. For energy savings, it is expected that fuel consumption in the operation of the HHP Boiler is as optimal as possible, so as to provide the appropriate heat. To find out the above, it is necessary to calculate the performance of the boiler. In this case the compilers use the Heat Loss method with dual fuel (fuel oil and fuel gas). From the evaluation results of the HHP Boiler with a heat balance, the efficiency is 89.53%.

Abstract

The carbonate in the Oliver formation is a potential reservoir in Browse Basin, Australia. The limited data is the main challenge in getting better knowledge about Oliver's carbonate. In this paper, the author will generate some geophysical and geological methods to solve the problem. The aim of this study is reservoir characterization using seismic attributes, describing the internal architecture, and determining the depositional model of Oliver carbonate.This study utilized 3D seismic data and one well data. The sensitivity analysis had been generated between resistivity vs P-Impedance log. Based on cross plot analysis, AI (acoustic impedance) log can be used to differentiate porous and non-porous carbonate in Oliver formation. Vertically, based on AI volume, Oliver carbonate can be divided into 3 phases: phase-1 carbonate is indicated by carbonate build-up with low AI (high porosity), phase-2 carbonate is indicated by carbonate build up with high AI (low porosity), and phase-3 carbonate is indicated by pro grading platform with low AI (high porosity).The conclusions of this study are 1) AI inversion method can be used to know the carbonate distribution related to facies, porosity, and depositional model in Oliver formation, 2) The potential reservoirs in this study area are in carbonate build-up and pro grading platform oriented to the southeast (carbonate B, carbonate C, and carbonate D). Carbonate A with unique geometry (elbow) influenced by the current trend had potential reservoirs in carbonate build-up and pro grading platform in phase 3 oriented to SW – NE. Carbonate E is located on an extensional platform that had a potential reservoir in the carbonate build-up.

Abstract

The physical properties of plastic waste that is not easily biodegradable is a serious problem in pollution on land and at sea. Therefore, technology to be able to solve these problems needs to be developed. This study aims to understand at what temperature plastic waste can produce fuel oil. The type of waste used in this research is polyethylene terephthalate (PET), which is a type of plastic that uses drink bottles. The design of the device to convert plastic into fuel oil in this study consisted of 3 components, namely a valve which functions to regulate the flow of steam from the reactor tube to the condensate tube, the temperature gauge functions to measure the temperature contained in the reactor tube, and the heat blanket functions as a coating, this can reduce excessive heat in the reactor tube. The results revealed that at a temperature of 100ºC to 150ºC with a variation of time (26.3, 27.3, and 28) minutes did not produce oil. At a temperature of 200ºC to 250ºC with time variations (33, 34, and 35) minutes, the condensate tube begins to produce fuel above the water surface.

Abstract

Foraminifera fossils will provide information on the relative age and depositional environment in the rock layers. foraminifera Fossil itself consists of two types, plankton and benthic foraminifera, which in a rock cannot be determined easily. Required methods are used to be able to decipher fossil foraminifera in the rock bodies. This method is called microfossil preparation. The precision in the execution process of the preparation will be very helpful in the process of further analysis of the fossil, which is the stage of determination. This stage will determine genus to species (taxonomy) of an organism based on the characteristics of each foraminifera. Each of the characteristics of foraminifera will show a unique tendency, both in the habitat when the organism is still alive until it can undergo fossilization.

Abstract

Cipluk Field is located in Klantung, Kendal, Central Java. It is an oil field in Indonesia. This field has abandoned status but until now oil seeps are found in the rocks around the field. Based on regional geology by Thanden et al. (1996), the estimated reservoir is Kerek Formation. The formation is exposed around and south of the field, around Lutut River. This research was conducted to determine the rock characteristics of Kerek Formation and to be analog to determine reservoir rock characteristics of the Cipluk Field petroleum system. This research is based on field evaluation data. Data were obtained through direct field investigations aimed at knowing the geological conditions of the research area. The main data used consisted of field observation data, rock samples, SRTM images, seismic data, and well data. Kerek Formation in the study area is divided into three members and only two members are exposed on the surface, Middle Miocene Kerek Formation and Late Miocene Kerek Formation. Middle Miocene Kerek Formation has characteristics with interbedded claystone-sandstone dominantly with limestone on the bottom and dominantly with sandstone on top. This member has a fairly good character as a reservoir for the Cipluk Field petroleum system based on its rock composition and geometry.

Abstract

Knowledge of explosion thresholds is essential to ensure a safe area. Fire or explosion may occur spontaneously if conditions in the area exceed the limits. Low explosive limit (LEL) measurements for 31 days have been carried out at Korpri Housing, precisely at Jl. Wilis Mukti 1, RT. 26, Kelurahan Sepinggan, Kecamatan Balikpapan Selatan, Balikpapan City, East Kalimantan. Measurements were conducted using a multimeter gas detector (compound gas monitor WT8811) for 31 days at three points, namely the first point was located about 5 m from the gas source, the second point was located at the gas source, and the third point was located around 20-25 m from the gas source. The measurement results revealed that the highest LEL value was at the second point with an average value of 4.79% LEL. The highest measurement results occurred on April 6, 2021 with measurement results in the morning at 09.00 WITA 14.8% LEL, afternoon at 12.00 WITA 13.8% LEL, and at 15.00 WITA 11.6% LEL. The results revealed that at the second point has the highest potential for an explosion.
