Abstract

Field or Field Marley is one of the fields in the work area of ​​PT. Pertamina Hulu Rokan, which is located in Riau Province, has entered the brownfield phase and has a high water cut rate. This condition made the company start a new step by making a size-up on the pump in the Marley well. However, after the Size-Up program was carried out there were several wells that failed, therefore in this study, the researcher will do a re-calculation to find out how far the success of the Size-Up program has been. After the Size-Up program was carried out at the Asmud well in the Marley field, the results obtained as much as 68% success, which is below the minimum target which should be above 100%. It is known that the pump installed in the Asmud well is a Centrilift 400P10 pump with a pump range of 650-1400 bfpd specifications, motor power 42 HP, electric current 53 A, voltage 475 V, and efficiency of 88.4%. Well data can be in the form of a 93% water cut, with an sfl value of 184 ft and a wfl of 307 ft, a pwf of 383.33 psi, and an API value of 34. Based on these parameters, the Inflow Performance Relationship (IPR) curve can be analyzed. it is analyzed that the Asmud well is in a down thrust condition where the pump is in the minimum range. Therefore, the researcher suggests that a Size-Down pump be carried out using a Centrilift 400P8 60 Hz pump with a specification range of 550-1200 bfpd which is in accordance with the production capacity of the Asmud well.

Abstract

Sel surya merupakan perangkat yang dapat mengubah sinar matahari menjadi energi listrik. Diketahui sel surya yang dominan digunakan saat ini memiliki kelemahan yaitu daya yang rendah, harga yang relatif mahal ditambah posisi dan sudut pemasangan yang konstan. Untuk itu perlu dilakukan suatu upaya agar kinerja sel surya dapat meningkat, upaya yang dilakukan adalah dengan menambah peralatan pendukung berupa solar tracker, reflektor, dan lensa fresnel pada sel surya. Kajian ini bertujuan untuk mendapatkan pengaruh peralatan pendukung pada sel surya terhadap kinerja sel surya dan mendapatkan peralatan pendukung terbaik untuk membantu meningkatkan kinerja sel surya. Pengujian dilakukan dengan memvariasikan 3 peralatan pendukung pada solar cell. Solar tracker adalah peralatan dan sistem yang dapat melacak sinar matahari terkuat, sedangkan reflektor dan lensa Fresnel berfungsi untuk meningkatkan intensitas sinar matahari melalui efek lensa. Hasil dan analisis uji kinerja yang telah dilakukan menunjukkan bahwa semakin lengkap peralatan pendukung yang ditambahkan, maka semakin baik pula kinerja yang dihasilkan oleh sel surya. Performa sel surya terbaik diperoleh pada peralatan pendukung pada hari ke-5 yaitu perangkat V dengan menggunakan solar tracker yang dilengkapi dengan lensa fresnel dan reflektor (STFR).

Abstract

This study aims to determine the of heat transfer absorbed by the high temperature superheater (HTS) and low temperature superheater (LTS) in boiler unit before and after the soot blower. This research uses 3 methods, namely, literature study, field observation, and interviews. The results of analysis show the heat transfer rate absorbed by the high temperature superheater (Q_HTS) increases after 1 hour soot blower, which is 72240 MJ/hour from (Q_HTS) 1 hour before soot blower, which is only 65434 MJ/hour, (Q_HTS) increases after 2 hours soot blower, namely 72575 MJ/hour from (Q_HTS) 2 hours before soot blower only 66886 MJ/hour and (Q_HTS) increased after 3 hours soot blower which is 73903 MJ/hour from (Q_HTS) 3 hours before soot blower only 69545 MJ/hour, then rate heat transfer absorbed by the low temperature superheater (Q_LTS) increased after 1 hour soot blower, which was 91797 MJ/hour from (Q_LTS) 1 hour before soot blower was only 89625 MJ/hour, (Q_LTS) increased after 2 hours soot blower being 92208 MJ/ hours from (Q_LTS) 2 hours before soot blower which was only 90267 MJ/hour and (Q_LTS) increased after 3 hours soot blower which was 92582 MJ/hour from (Q_LTS) 3 hours before soot blower only 90536 MJ/hour.

Abstract

Indonesia's electricity plants mostly use off-renewable resources to meet the electricity needs of people or industries such as coal. This crisis problem requires that we seek a fuel alternative to replace coal or at least reduce coal consumption. One of them biomass fuel by applying co-firing methods. The co-firing process aims to raise thermal energy in the boilers, and therefore it is expected to raise the heat rate of the boiler fuel. The application of research uses a comparative analysis method that will compare heat rate using co-firing method with heat rate without the co-firing method. Analysis shows the impact of adding biomass waste as a boiler fuel to create a heat rate with co-firing increased by 19810.41 kkal/kWh compared to the time without co-firing 19207.08 kkal/kWh. The test also affected its carbon content of 57.62% increased 57.88%, while in total sulfur from 0.20% to lower by 0.19%.

Abstract

The lack of maximum use of alternative energy, especially water energy, so this research will be carried out with water turbines, namely vortex turbines. This turbine utilizes a water vortex to drive the blade and can operate at a relatively low head. This study aims to determine the effect of blade type on the power and efficiency of a more optimal turbine and get the best analysis results on the comparison of straight and curved blade type impellers on the power and efficiency of a 205 mm, 210 mm, and 215 mm high impeller vortex turbine with a total of 9 blades. The method used in this research is literature study, preparation of tools and materials, data collection then data processing and analysis. The results of this study compared to the straight blade impeller, the curved blade impeller gets the highest value of turbine power and efficiency. more details the curved blade impeller with a height of 215 mm and the number of blades of 9 pieces produces the highest turbine performance in this study. The resulting turbine power (Pt) is 46.77 watt and the resulting turbine efficiency (ht) is 13.41%. While in the straight blade type impeller the turbine power and efficiency results are lower than the curved blade type impeller. Especially the 205 mm straight blade impeller with 8 blades has the lowest power and efficiency results.

Abstract

This study discusses the percentage comparison of fiber and palm shell fuel mixtures by having several different percentages, so that the best percentage of fuel for boiler performance is obtained. In this case the calorific value of the fuel plays an important role in determining the efficiency of the boiler, where the higher the calorific value, the less fuel is used. So that it greatly affects the performance of the boiler and is more economical in saving fuel. Retrieval of boiler data at PKS PTPN V Sei Galuh. In the form of fuel composition and boiler unit parameters obtained using water and steam properties software which is then carried out research to find the best percentage of boiler fuel. Based on the results of the research that has been done, the best results are obtained at the percentage of 75% fiber fuel and 25% palm shell with 86% efficiency, fuel consumption of 759 kg/hour, boiler capacity of 40.091,8 kg/hour, consumption combustion air of 8.500,401 kg.air/kg.fuel, and the heat generated is 23.213.235,24 kcal/hour or 23.21×106 kcal/hour. With the results of this study, the boiler can produce electrical energy of ± 1 Megawatt with electricity requirements to run the entire performance of the machine for one day of ± 0,8 Megawatts.
