Abstract

Energy and Mineral Resources Ministry's 2018 Electricity Statistics data shows that the installed capacity of Solar Power Plants (PLTS) only reaches 0.09 percent of the national generating capacity. This means that if the national generating capacity in 2018 reaches 64.92 gigawatts (GW), then PLTS only has a share of around 58.43 megawatts (MW). This value is very small considering the potential for solar energy in Indonesia can reach 207 GW. The majority of power plants in Indonesia are still dominated by PLTU which reaches 42.34 percent or around 27.49 GW. In testing the characteristics of solar panels, the method used is to install prototype materials and equipment for 100 WP Polycristalline solar panels and collect data through direct measurements. The method of observation is to collect data related to temperature variations that are happening at certain times and conditions that can affect the size of the power. The equipment used for this measurement includes: a thermometer used to measure temperature, a Charge Controller Module (SCC) as a control for charging the battery as well as measuring the amount of DC electricity that is always displayed, a camera for documenting the measurement results, a battery as a store of electrical power and a dc wattmeter as a measurement tool. the amount of electricity from the solar penel as well as connecting cables and other auxiliary equipment. The results of this study include: the pattern of power characteristics on a Pollycrystalline 100 WP solar panel at a temperature of 25˚C to a temperature of 39˚C is directly proportional to temperature, with a minimum value of 2.7 Watt at a temperature of 25˚C until it reaches a maximum power of 28, 5 Watt when the temperature reaches 39 C, the SUNSIA brand of Pollycrystalline 100 WP solar panel can produce effective electrical energy when the temperature is above 34 C, from the power generated by the solar panel to charge a 12 V 32A battery with an initial voltage of 5.1 Volts until it reaches a voltage of 13.8 Volts takes 8 hours.

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

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

Efficient use of energy is a top priority in the oil and gas industry, the aim is to reduce operational costs, one of these efforts can be done by utilizing the heat from the process to heat the feed before it is heated in the furnace, as is the case with heat exchangers. The effectiveness of the heat exchanger indicates the performance of the heat exchange process in the heat exchanger, both by convection and conduction. Over time, the effectiveness of the heat exchanger will decrease due to fouling formed and other things that can reduce the effectiveness of the heat exchanger. Through the performance evaluation, the performance of the heat exchanger can be indicated which can be used for future maintenance and repair plans. Thermal effectiveness was calculated using the dirt factor and pressure drop methods, and the calculated operating fouling factor was 0.002 Btu.ft2.°F /hr, this condition exceeded the maximum allowable design limit of 0.005 Btu.ft2.°F/hr, while the calculated pressure drop is 2,72 psi. This condition is still below the maximum allowable design limit of 10 psi, so this heat exchanger is still feasible to use. Calculation of the effectiveness of the heat exchanger results in an effectiveness of 34,075%.

Abstract

PPSDM Migas has an oil refinery with a capacity of 600 m3 per day where the crude oil produced will produce various products, such as pertasol CA, pertasol CB, pertasol CC, naphtha, diesel, and residue. One of the operating units used in this production process is a heat exchanger which aims to minimize the use of fuel in the furnace heating process. Of the five heat exchangers in the field, one of the heat exchangers was damaged, namely HE-05. Therefore, an analysis of the causes of damage to HE-05 was carried out with research methods in the form of field studies and literature studies, such as data collection on operating conditions in the Distributed Control System (DCS) and directly in the field using the Piping & Instrumentation Diagram (P&ID) so that it can calculate overall mechanical energy balance. Based on the results of the analysis, it can be concluded that the water content in crude oil exceeds the threshold (< 0.7%) of 5.5%. High water content will affect the steam fraction of crude oil which results in an increase in operating pressure. Then, the safety valve on the stabilizer did not work so that the gasket of the HE-5 was unable to withstand the high pressure in this incident. In addition, inaccurate pressure and temperature sensor readings cause operator delays in dealing with these incidents. Keywords: Crude oil, heat exchanger, water content

Abstract

The ignition quality of diesel fuel in diesel engines is expressed by the cetane number. In this study, the cetane number was determined using an empirical correlation between density and distillation temperature using the Calculated Cetane Index (CCI) ASTM D 4737 standard. Cutting the boiling point of refinery diesel is carried out to determine its effect on the Calculated Cetane Index (CCI) value. Cutting the boiling point route is done by cutting distillation into 3 variations. The Calculated Cetane Index is measured by calculating the density data of ASTM D 4052 and ASTM D 86 distillation. Solar Feed, which initially had a CCI value of 46, was cut by its heavy fraction in stages to variation 2, the value decreased to 41.6. In variation 3, the light fraction was cut in stages, the result showed that the CCI value increased to 55.2. The results of the Fourier Transform Infrared Spectroscopy (FTIR) characterization showed the presence of C-H stretching and C-H bending functional groups at wave numbers 2900 cm-1 and 1456 cm-1 The higher the hexadecane composition, the higher the CCI value. The results of the analysis using the Gas Chromatography-Mass Spectrometry (GC-MS) instrument proved that Solar 3.4 has the highest hexadecane composition of 10.19%. Solar Feed has a hexadecane composition of 6.45% while Solar 2.4 has the lowest hexadecane composition of 4.56%. Keywords: Diesel Fuel, Cetane Number, Calculated Cetane Index, Distillation
