This research investigates the heavy metal contamination and water quality on the immune response (IL-1 β ) of wader fish ( Barbonymus gonionotus ) in response to the presence of contaminants in the waters of the Porong River. The location area was selected because of its diverse utilization surrounding the river, including residential areas, industrial zones, and agricultural practices. The research procedure includes water quality measurements, plankton analysis, heavy metals exposure, and immune response (IL-1β) detection by PCR. In general, the waters of the Porong River were found to be polluted based on the assessment of water quality, as indicated by the measurement of CO 2 , TDS, TSS, and salinity parameters surpassing the established threshold values. In the waters of the Porong River, the metals Cu, Hg, Cd, and Pb exhibited a descending order of penetrating power as follows: Cu > Hg > Pb > Cd. Conversely, in the sediment samples, the order of penetrating power was Cu > Pb > Cd > Hg. The PCR amplification results indicated the presence of IL-1β response in all examined fish, suggesting that it could be attributed to water contamination throughout the entire sampling site. In addition, the heavy metals contamination in the waters of the Porong River resulted in high expression of IL-1β in the fish sample. The findings lead to the conclusion that the waters of the Porong River are classified as polluted based on the measurements of water quality parameters, namely CO 2 , TDS, TSS, and salinity, which surpass the threshold values established according to Government Regulation (PP) of the Republic of Indonesia Number 22 of 2021.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the potential of depleted fields in the North West Java Basin as the target for CCUS-EOR in fulfilling the zero CO 2 emission program and boosting oil production. The study uses oil and gas field data to evaluate the CCUS potential both qualitatively and quantitatively. The Geographic Information System was applied through a clustering method with a 50 km and 100 km buffer from CO 2 emission sources. The calculation of CO 2 for EOR purposes with a 50 km buffer radius is 287.504 million tons, which could result in a 575.009 million stock tank barrel (STB) increase in oil production in the case of immiscible injection and 379.506 million tons for an increase of about 1.150 billion STB of oil production in the case of miscible injection. For a 100 km buffer radius, 632.541 million tons of CO 2 is required to increase 1.265 billion STB of oil production in the case of immiscible injection and 834.955 million tons of CO 2 for an increase of 2.530 billion STB of oil production in the case of miscible injection. These results are expected to be implemented as part of the program to reach the goal of producing 1 million barrels of oil per day by 2030 and achieving net zero emissions by 2060.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691565","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It functions as the center of the community's economy, used for the purposes of the entry and exit of goods and human activities in it. To be in accordance with its function, a port must have complete facilities. One of the ports that does not meet the criteria mentioned above is the Port of Pota. The port of Pota has not yet operated; one of the reasons is that it does not yet have a stipulation for shipping lanes. The process of making shipping lanes involves dredging in order to get the appropriate depth; it is very important to conduct an investigation of the suspension material. Therefore, research on sediment transport is the basis for the development of port development and aims to be able to determine the hydro-oceanographic conditions in the waters of Pota Harbor. Based on the results of sample testing, it shows that the highest sediment content is at low tide, reaching 0.0087 g/L and the lowest is at high tide, reaching 0.0057 g/L. The simulation results of sediment levels for 24 days show that there is an increase in concentration at Pota Harbor of 0.94 kg/m3. The waters of the Port of Pota have a dominant current direction that tends to be parallel to the shoreline, or it can be said that the currents that occur in these waters are tidal currents. There is a stirring of sediment on the shore, which is then transported by currents and settles as the current velocity decreases due to shallower depths.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The inverter is designated at an operating frequency as high as 13.56 MHz in line with regulations for the industrial, scientific, and medical radio band (ISM band). Since the power is transferred wirelessly from the source to the EV, a coupling capacitive was used as a transmitter and receiver of the system. In this paper, the inverter model was simulated and analysed using LTSpice software. Different load changes and power are injected into the system. Furthermore, in order to obtain a robust system, the switching frequency of 13.56 MHz is used with some Dead Time (DT). The system already uses GaN MOSFETs for reliability and performance at high frequencies, in addition to LC impedance matching. The result is that by operating at a resonant frequency of 13.56 MHz with a resistive load of 50, it is obtained with a power of 2.3 kW that has been successfully transmitted with an efficiency of 89%.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135691585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It entails establishing the best settings of control variables to minimize generating costs while meeting operational restrictions. Traditional optimization techniques often struggle to handle the complexities and uncertainties inherent in power systems. This paper introduces fuzzy systems' concepts and their integration with genetic algorithms. It then delves into the many possibilities for power system optimization problems. The first section introduces the fundamental ideas of fuzzy, while the second section explores its structure and components. The third section explores the genetic algorithm's synergism with the fuzzy technique. The suggested technique was evaluated on an upgraded IEEE 30-bus system, with an optimal solution indicating fuel cost reduction under various linear and non-linear constraints. The suggested methodology's results were compared to all those mentioned in the literature. The outcomes of the offered methodologies are encouraging, demonstrating the efficacy and resilience of the proposed procedures. The synergism of the fuzzy system with the genetic algorithm offers several advantages, including flexibility in handling uncertainties, adaptability to complex systems, and the potential for discovering innovative solutions. However, it is important to carefully design the fuzzy system's rule base and appropriately set the genetic algorithm's parameters for optimal performance.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For this purpose, initial and final water temperature were measured at nine different configurations, and then the thermal efficiency value at each configuration was determined. The reference test method for energy performance of LPG Gas Stove constituted in Indonesia National Standard SNI 7368:2011 was employed to determine the thermal efficiency of the LPG Gas Stove. A coverage interval method was applied to estimate uncertainties and to reliably compare the thermal efficiency measurement. It is found that the thermal efficiency values of temperature position variations are statically similar to the reference point. The interval level of estimated thermal efficiency values ranges from 2.49% to 2.65%. Furthermore, the temperature measurement is found to be the dominant contributor to coverage interval value of thermal efficiency estimation. Therefore, the temperature measurement of the water volume inside the vessel must be specified in the test method in the standard.","PeriodicalId":12085,"journal":{"name":"Evergreen","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135690310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
