ABSTRACTThe off-grid PV system is an alternative power generator as a replacement for the conventional system which is currently still used in production operations at petroleum companies in Indonesia. The application of this offgrid PV system can support oil production operations for companies whose production areas are in remote areas or are still not reached by the PLN network and can reduce the consumption of fossil fuels to run generators so as to reduce greenhouse gas emissions and as a step to utilize the potential of Indonesia's sunlight. This research was carried out using a theoretical study method, namely by processing data obtained from the field using equations obtained from supporting references. This research shows that to meet the electricity needs of a centrifugal pump that operates 5 times a day with one operation of 7.5 kW for 1 hour and the total daily need is multiplied by 2 to calculate cloudy days, 75 kwh of energy is needed a day. The results of the research show that 40 solar panels with a capacity of 450 Wp each installed in series are needed and 80 LIFEP04 batteries made in battery banks totaling 20 banks with 4 batteries each, and 4 5000W inverters so that they can produce 75kWh of power and meet daily load requirements. Key words: offgrid PV system, Centrifugal Pump, parallel series

ABSTRACTThe Ambon Peaker Gas Power Plant (PLTMG Ambon Peaker) is an electrical infrastructure facility powered by gas turbines, located in Waai Village, Central Maluku Regency, Maluku Province. The fuel oil storage tank used by the Ambon Peaker since 2019 is situated directly near the coastline, making it very vulnerable to damage, particularly from corrosion on its metal plate walls. Therefore, maintenance is necessary to prevent any unwanted workplace accidents. This tank stores fuel oil. The author conducted calculations for minimum thickness and corrosion rate to determine the remaining lifespan of the tank. The results indicate that the critical point is located at course 1, with a remaining lifespan of 121 years. This can be influenced by various factors, such as environmental conditions and fluid characteristics. Tank maintenance also needs to be considered to ensure the tank's reliability, allowing it to operate longer and preventing the need for corrective maintenance. Keywords: storage tank, corrosion rate, wall thickness, remaining life.

Design of PLTS is an effort to enhance the reliability of electrical power, electrification ratio, and utilization of renewable energy in the oil and gas industry. The availability of electricity is extremely urgent to meet the production process requirements, particularly for the motor-driven SRP pumping system. Currently, the industry relies on PLN and genset electricity for daily production activities. However, the design of a centralized PLTS system is expected to meet the SRP electricity needs in the oil and gas industry. The power grid in the oil and gas industry is obtained from PLN and genset. Therefore, the need for a power plant is evident. Related to the research previously discussed with the title â€œDesign of Centralized PLTS as an Alternative Electricity Supply for Sucker Rod Pumpâ€ (Pinky Kartikasari, 2024), this study aims to determine the capacity of panels and batteries required for the development of a centralized PLTS in the oil and gas industry. The method used in this research is quantitative because it involves calculating the capacity of solar panels, daily energy needs, and numerical system analysis. The results show that the total energy requirement for SRP electricity supply is 264 kWh/day. The required capacity of panels is 106 kWp, with a total of 200 monocrystalline panels each with a capacity of 550 Wp. Additionally, there are 128 batteries with a capacity of 24V 200Ah. The inverter used is the PV1800 ECO Series 6.200W type, with 20 units in total. Keywords: PLTS (Solar Power Plant), SRP (Sucker Rod Pump), Oil and Gas Industry

Corrosion resistance is the most important criterion in determining both the service life (remaining life) and operational reliability of equipment in the oil and gas industry. So it is very important to monitor the performance of every equipment in this industry. As with storage tanks, during long periods of operation and use, performance will likely decrease or could be said to experience thinning, thereby posing a danger to the thickness and remaining life of the ultrasonic thickness measuring instrument. differences in steel thickness data from the beginning and the thickness carried out by researchers. The data collected is also data that determines the minimum value for steel thickness in order to calculate the useful life of the media that will be examined by tanks that carry out measurements and maintenance using API 653 standards. Take measurements at several points 1. From the results of the analysis of the 100KL Tank located at PLTD HARUKU Using the UTG-90 Ultrasonic Thickness Gauge tool for plate thickness in August 2024, the results were that for Course 1 3.3, Course 2 3.4, Course 3 4.1, and Course 4 4.0 and the remaining tank life for each -Course 1, Course 2, Course 3 and Course 4 respectively are 11.26 years, 11.86 years, 32 years, 27.8 years1. The 100KL tank needs to undergo a Remaining Life Assessment (RLA) in 2028 and a regular tank inspection routine must be carried out to prevent leaks in the tank at least once every 4 years.

Microalgae Navicula sp. TAD is a microscopic plant that has the potential to serve as an alternative source of pigments, requiring relatively short cultivation time, making it suitable for use as a sensitizer in dye-sensitized solar cells. This research aimed to isolate, characterize, and identify the photosynthetic pigments of Navicula sp. TAD, and subsequently test its photoelectric capability as a sensitizer material in solar cells. The study involved cultivating Navicula sp. TAD cells to obtain biomass, isolating pigments from dry biomass, purifying pigments using column chromatography techniques, characterizing pigments by scanning visible light absorption patterns, and fabricating solar cells with TiO2 paste, followed by testing the photoelectric capabilities of the solar cells. From the research, pigments such as β-carotene, chlorophyll a, xanthophyll, and chlorophyll c were obtained, with chlorophyll a and carotenoid contents of 29.9698 μg/mL and 18.4255 μg/mL, respectively. Solar cells sensitized with photosynthetic pigments showed the best photoelectric performance with crude pigment extract at a concentration of 30×10³ ppm, yielding Short-circuit current density (ISC) 1.93×10⁻⁵ A; open-circuit voltage (VOC) 0.0465 V; fill factor (FF).58; and efficiency (η) 8.33×10⁻² %. Meanwhile, variations in pigment concentration of chlorophyll and xanthophyll at a ratio of 0:100 yielded ISC 9.96×10⁻⁵ A; VOC 0.1004 V; FF 0.45; and η 7.24×10⁻¹ %.

Ambon Peaker 30 MW. These pipes are prone to corrosion, especially if not protected by a coating, which leads to thickness reduction and shortens the operational lifespan of the pipes. The thickness measurement will be carried out using an Ultrasonic thickness gauge to determine the corrosion rate and the remaining life of the pipe. The standards referenced in data collection are the American Petroleum Institute (API) 570 and the American Society of Mechanical Engineers (ASME) B31.4. The research will be conducted by the author from August 28, 2024, to August 30, 2024, at PLTMG Ambon Peaker 30 MW, Salahutu District, Central Maluku Regency, Maluku Province. The research results show that the minimum thickness reduction indicates a corrosion rate of 0.228 mm/year at Thickness Measurement Location (TML) 17 and 18, while the maximum thickness reduction shows a corrosion rate of 0.564 mm/year at Thickness Measurement Location (TML) 3. Pipes with lower corrosion rates have a remaining life of 5.4 years, while pipes with higher corrosion rates have a remaining life of up to 31.9 years. In conclusion, coating protection is essential to reduce the corrosion rate and extend the service life of the pipes. Keywords: Pipe thickness, Corrosion rate, Pipe remaining life, Ultrasonic thickness gauge.
