Optimasi laju produksi dengan cara desain ulang sucker rod pump pada sumur “EP” lapangan “NM”

Background: In general the production method is divided into two, namely natural flow and artificial lift. Natural spray is a method of flowing fluid from the perforation zone to the surface of the well naturally, this is due to the reservoir pressure that drives the fluid up to the surface is still very high. Along with the time of production, a decrease in reservoir pressure will occur and this condition will reduce the level of production of the well, so to overcome this problem can be done by artificial lift. The purpose of the artificial lift is to help lift fluid from the well to the surface. Methods: One method of this appointment is the sucker rod pump. To increase the productivity of a pump sucker rod pump, it is necessary to pay attention to the pump production capacity, step length, pumping speed, and location of the pump depth. Finding: EP wells are oil and gas wells in the Kenali Asam Atas field, PT Pertamina EP Asset 1 Field Jambi. Based on Vogel's IPR curve analysis, the maximum production rate (Qmaks) for EP wells is 1089 BFPD. Conclusion: Based on the results of the analysis and optimization that has been done, the production rate that can be achieved by EP wells is 762 BFPD

The selection of critical angle in determining the magnitude of reactive power supply

Background: At this time electricity problems play an important role in increasing the demand for active and reactive power because the industry is increasing which requires increasing electrical power as well. Methods: One of the supporters of overcoming this problem will be an analysis of solving it. It is common for electrical engineering engineers to know about the stability of the power distribution system, which in the following analysis is an analysis of the selection of the critical angle of the power angle.

The three active power, reactive power, and apparent power are directly related to each other, meaning that active power is directly related to reactive power as well as directly related to apparent power. Conclusion: So the amount of active power is directly related to the size of the reactive power or directly related to the size of the apparent power. Novelty/Originality of This Study: This study presents a novel analytical approach to determining the critical power angle in power distribution systems, highlighting the direct interdependence between active, reactive, and apparent power to enhance system stability in response to increasing industrial electricity demand

Finding: Several policy recommendations based on the pentahelix scheme are proposed. The government should establish regulations and provide incentives for biomass energy from agricultural waste, as well as promote infrastructure investments. Private corporations should engage in technology development and partnerships with farmers. The community should be educated about the importance of agricultural waste management and encouraged to participate in biomass energy programs. Media should disseminate information and cover biomass energy projects. Academics should research new technologies and conduct training to enhance farmers' capacities. Conclusion: Therefore, biomass energy can be developed as a solution to achieve energy security and national economic development. Novelty/Originality of This Study: This study offers a novel integrative approach by applying the pentahelix model to formulate comprehensive policy recommendations for optimizing biomass energy utilization in Indonesia

Effect of immersion in ordinary water (PH7) with time variation on the bending strength of composite water gates

Background: Glass fiber reinforced polymer (GFRP) composites have a disadvantage in terms of bending strength. The use of unsaturated polyester (UP) can enhance the strength of GFRP. However, good mixing is required to ensure proper bonding between the UP and fiberglass as the filler. This study aims to investigate the effect of UP and mixing conditions on the bending strength properties of GFRP/UP composites. UP polymer, glass fibers, and methyl ethyl ketone peroxide (MEKP) (1wt%) and cobalt were used as the matrix, reinforcement, and compatibilizer, respectively, to fabricate the composite. Methods: MEKP (1wt%) and cobalt were mixed using a manual method. Finding: UP-glass fiber-MEKP (1wt%) and cobalt composites were made using the hand lay-up process. The hand lay-up technique is a common method for combining resin and fiber. Its main advantage is that it can be used to produce large and complex samples. Conclusion: The results of the study concluded that composites with UP-glass fiber-MEKP (1wt%) and cobalt did not perform well in withstanding bending strength. Significant changes in sample strength were observed with different mechanisms over periods of 360, 720, and 1080 hours. Novelty/Originality of this article: This study found that, although the addition of UP, glass fiber, MEKP, and cobalt offers potential for improving composite strength, the resulting material is not strong enough to withstand bending forces in practical applications

Finding: If in the free environment, air, temperature, and acidic substances are most commonly found as a factor causing corrosion. The increased corrosion rate is due to the higher concentration of the cause of corrosion. Conclusion: In this discussion, HCl as a concentration is used, and aluminum as a metal is tested

Pengaruh suhu, waktu perendaman, dan inhibitor alami terhadap laju korosi pada pipa tembaga di lingkungan asam HCL 0,1 N

oai:ojs2.journal-iasssf.com:article/735Background: A pipe is a cylindrical casing used to convey liquid or gas fluid. Methods: In this study, we experimented with creating a composite with an HDPE resin matrix, while its filler is CaCO3 with compositions of 0, 4, and 7 (per one hundred of resin). Finding: Based on standards in its production, pipes are typically based on their nominal diameter, usually having a fixed outside diameter (OD) value while their thickness uses the term schedule, which varies in value.
