Abstract:
PPSDM Migas Cepu processes crude oil from PT.  Pertamina EP Asset 4 Cepu Field becomes Pertasol CA, Pertasol CB, Pertasol CC, Solar and Residue, through the Crude Distillation Unit (CDU) process in the refinery unit.  In the early stages of the process, the raw material in the form of crude oil is heated in a heat exchanger and then reheated in the furnace until it reaches a certain temperature to flow to the next stages.  A heat exchanger is a heat transfer device between a hot fluid and a cold fluid, without the need to mix the two fluids.  HE-002 shell and tube type is one of five heat exchanger units owned by the PPSDM Migas Refinery unit.  HE-002 plays a role in heating the cold fluid in the form of crude oil which is placed in the tube and flows the hot fluid in the form of diesel fuel through the shell.  Heat transfer can occur due to temperature differences between fluids.  However, in actual conditions, the amount of heat released by diesel and the heat received by crude oil is not of the same value.  This study aims to determine the heat transfer efficiency on the HE-002 by comparing the heat changes in the hot fluid and cold fluid.  After data collection and calculations, the efficiency of the HE-002 PPSDM Migas Refinery unit was 94.463% with a heat loss percentage of 4.753%.

Abstract:
Energy is an important factor for the sustainable development of a country. The political crisis that occurred between Russia and Ukraine has had a significant impact on trade and commodity price fluctuations, especially in the energy sector. The sanctions imposed on Russia caused global supply cuts from that country which resulted in limited availability of commodities so that prices rose. The increase in global commodity prices also had an impact on the country of Indonesia. This study aims to analyze the impact of the Eastern European crisis on Indonesia, especially trade and commodity price fluctuations in the energy sector. The method used in this research is a literature study so that relevant information is obtained. then the information is analyzed as Strengths, Weakness, Opportunities, and Threats. The results of the study show Indonesia's economy is currently still quite good, the increase in oil energy commodity prices is detrimental while gas, coal, and CPO are profitable for Indonesia. The crisis that has occurred has had a beneficial or detrimental impact on the Indonesian state.

Abstract:
Heavy oil is generally composed of hydrocarbons as the main component and several types of impurity compounds in small amounts.Cracking with aquathermolysis method is one way to reduce the physical properties of petroleum residues. Aquathermolysis utilizes water as a solvent at temperatures above the boiling point of water with the help of active materials as cracking agents. This research examines the effect of NiO/Fe3O4 catalyst which is synthesized by coprecipitation method in aquathermolysis reaction of Oil and Gas PPSDM Residue.The aquathermolysis reaction was carried out in a stainless steel batch reactor system.The results shows that the catalyst which is obtained is trevorite crystal Fe1,7Ni1,43O4 and has shown having catalytic activity in the aquathermolysis reaction of Oil and Gas PPSDM Residue. The aquathermolysis reaction to the uncatalyzed residue increased the aliphatic content and decreased the aromatic content in the residue, while the reaction with the catalyst decreased the aliphatic and aromatic hydrocarbon content.Both reactions increase the levels of heteroorganic compounds. If  the ratio of the catalyst to the reactants getting weighter,cause the viscosity of the reaction products getting lower.When compared with the initial residue, the decrease in the viscosity of the reaction product without catalyst, catalyst/reactant = 0.002 ; and catalyst/reactant = 0.01 3.00%, 3.33%, and 6.00%, respectively. The greater the ratio of residual

Abstract:
Minyak dan gas mememiliki potensi yang besar, tetapi pada kenyataanya industri hulu minyak dan gas merupakan usaha yang membutuhkan modal sangat besar dan beresiko tinggi khususnya di tahap eksplorasi, sehingga untuk pelaksanaannya memerlukan peran para investor. Upaya yang dilakukan untuk peningkatan iklim investasi tersebut dilakukan mulai dari penyederhanaan regulasi, jaminan keamanan, termasuk intensif yang diberikan kepada investor. Pemerintah melakukan usaha dengan menarik investasi melalui intensif pajak agar para investor tertarik melakukan penanaman modal meskipun dihadapkan dengan resiko yang besar khusunya pada tahap eksplorasi. Intensif pajak bagi investor dibagi menjadi dua jenis, dalam bentuk investment allowance dan tax holiday. Salah satu alasan investor tidak berinvestasi yaitu akibat penurunan keekonomian proyek akibat pengembangan migas kian sulit, contohnya cadangan saat ini banyak berada di deepwater sehingga memerlukan teknologi yang mahal dengan pajak yang tinggi, inilah alasan pemerintah memberikan insentif pajak. Disebutkan pada PP Nomor 27 Tahun 2017 sebagai pembaharuan dari PP Nomor 79 Tahun 2010 tentang Biaya Operasi yang Dapat Dikembalikan dan Perlakuan Pajak Penghasilan di Bidang Hulu Migas, bahwa setidaknya terdapat tujuh insentif pajak yang ditawarkan oleh Pemerintah Indonesia. Maka dengan adanya PP Nomor 27 Tahun 2017 dan Invesment Credit (Insentif Pajak) dapat menjadi solusi yang tepat bagi kedua belah pihak dan dapat menarik minat investor untuk berinvestasi di industri migas di Indonesia.

Abstract:
The present study main focused on reservoir Characterization of the Upper Cretaceous Kawagarh Formation from Qamar Mela Section, Nizampur Basin. The samples were collected from the field by using standard procedures involving section measurement, lithological logging and photography. The collected samples were used to prepare the thin sections followed by petrographic analysis using Optika microscope in the laboratory. To explore the reservoir potential, we studied the impact of diagenesis on reservoir potential, supplemented by plug porosity and permeability, and SEM analysis. The outcrop is mainly composed of limestone and marl. Fifteen samples were studied from 45m thick section and two main microfacies were identified. The microfacies includes; (1). Mudstone microfacies (planktonic foraminiferal mudstone and dolomitic mudstone sub-microfacies), (2). Radiolarian bioclastic planktonic foraminiferal wackestone microfacies. The environment of deposition interpreted on the basis of microfacies for Kawagarh Formation is inner ramp to outer ramp and deep basinal settings. The Kawagarh Formation is also modified by various diagenetic features including compaction, dolomitization, dissolution, pyrite precipitation, cementation and spar filled fractures representing meteoric to marine phreatic with mixing zone and burial diagenetic environments. Dissolution, fracturing and dolomitization are the diagenetic processes which enhanced the porosity while cementation, pyrite precipitation and compaction decreased the porosity. Plug porosity and permeability of four rock samples averages 1.69% and 0.267 Ka/md, respectively. SEM analysis shows different types of porosity includes vuggy, shelter and intergranular. The low porosity and permeability levels of Kawagarh Formation suggest only a modest reservoir potential.

Abstract:
Sumur tua minyak bumi yang ada di Indonesia mencapai 13.824 sumur dan 745 sumur masih aktif. Di beberapa tempat sumur tua ini di eksploitasi dengan cara tradisional salah satunya lapangan minyak di desa Wonocolo. Penambangan minyak yang dilakukan masyarakat masih menggunakan peralatan sederhana. Penambangan tradisional minyak bumi selain memberi dampak positif dalam peningkatan produksi minyak bumi nasional dan pendapatan masyarakat, tetapi juga memiliki dampak negatif yang ditimbulkan yakni pencemaran lingkungan. Limbah utama yang dihasilkan dari kegiatan penambangan minyak adalah air terproduksi, terutama pada sumur tua yang memiliki water cut diatas 90%. Penelitian ini bertujuan menganalisis kualitas air sungai penerima air limbah kegiatan penambangan tradisonal minyak bumi di Desa Wonocolo berdasaran PP Nomor 82 Tahun 2001 dengan fokus pembahasan parameter DO, COD, BOD dan minyak dan lemak. Hasil penelitian menunjukkan kualitas air sungai pada daerah hulu kondisinya masih baik, sedangkan pada daerah hilir beberapa parameter nilainya diatas baku mutu air kelas II.

Abstract:
This study examines the performance of a solar power plant with a total capacity of 125 KWp, which operates for one year in Blora, Central Java. The ability of this power plant is a total of PV modules with 20 kWp, ten kWp, and five kWp capacities spread across eight locations. The annual performance of the rooftop solar power plant is measured automatically by the converter installed in each module. The resulting data from inverters are compared to the meteorological conditions from the meteorological agency. This research will investigate the influence of climate on the power generated, the efficiency of the equipment in a power plant, and the effect of pseudo motion of the sun. It was found that there were variations in energy output throughout the year, and it was concluded that the maximum annual energy was produced in July-August. In addition to weather, other factors need to be investigated further to determine the causes of variations in solar PV output.
