Abstract

 PT. PLN Nusantara Power UP Tenayan is a company operating in the power generation sector and focuses on operating PLTUs Tenayan, Indonesia. One part of the machine that influences the operation of the generator is the boiler feed pump. Lack of optimal boiler feed pump instrumentation often results in failure in operating activities. This research uses the Failure Mode and Effect Analysis (FMEA) method with the research objective of finding out the causes of failures that occur, identifying the type of failure, and determining the RPN value and the impact that occurs. The analysis results, it shows that the Boiler Feed Pump instrumentation components still meet operating standards because the Risk Priority Number (RPN) value is below 200, even though the Speed Sensor has a fairly high RPN value but is still in the reliable category, the result of identifying the type of failure that occurs is that the indicator reading is not actual, the component is not functioning, the highest RPN value for the Boiler Feed Pump component is the Speed Sensor component with an RPN value of 160 and the lowest RPN value is for the pressure indicator component with an RPN value of 30. The most important recommended action for the Speed Sensor component is to carry out maintenance for 1 month very.Keywords – Boiler Feed Pump, FMEA, Keandalan, Pembangkit, RPN.

Abstract

The behaviors of motorcycle drivers are rarely studied, while their behaviors caused  considerable danger on driving safety. This study aims to identify risky behaviors of motorcycle drivers. This study was conducted in some roads in Jakarta and Bekasi by adopting the work sampling technique. The results showed that risky behaviors were mainly dominated by not wearing a helmet and by carrying more than one person. These behaviors were most commonly found in areas where it was perceived that there was no police and Electronic Traffic Law Enforcement (ETLE), especially in the Bekasi area. The presence of the police is crucial in preventing risky behavior of the drivers. Therefore, it is recommended to further ensure the presence of the police in areas prone to risky behaviors, especially when ETLE is not yet installed, or when it has not been fully applied. Keywords – Motorcycle, Passengers, Risky Behaviors, Work Sampling.

Abstract

PT. Kurnia Luwuk Sejati or PMKS Toili is one of the palm oil industries that processes fresh fruit bunches into Crude Palm Oil and Palm Kernel Oil. Due to high market demand, palm oil plantation workers are required to complete their tasks on time with a target of 8 working hours per day. Several workers have complained about the physically and mentally burdensome nature of their work, leading to harvest results that sometimes do not meet the desired quality standards. This research aims to determine the level of mental workload experienced by the workers using the SWAT and Work Sampling methods processed using the DosBox 0.74 application. The measurement results can indicate the extent of mental workload perceived by the employees, with three significant factors influencing the employees' mental workload: the time dimension accountsfor 67.16%, the effort dimension accountsfor 13.87%, and the stress dimension accounts for 18.97%. Recommendations for improvement need to be implemented to minimize and reduce the employees' workload, including improving working conditions and the work environment, increasing rest time, effectively distributing tasks, and increasing the number of operators or employees to achieve production targets.Keywords – Mental Workload, SWAT, Work Sampling

Abstract

The substantial development of the palm oil industry in Indonesia is evident in the high production of Crude Palm Oil (CPO) as the primary product and Palm Oil Mill Effluent (POME) as a byproduct in palm oil mills. POME waste contains emissions that can harm the environment, necessitating proper waste management. This issue can be addressed by transforming the waste into biodiesel, as it still contains Free Fatty Acids (FFA) and triglycerides. The utilization of biodiesel can reduce the reliance on fossil fuels and environmental pollution. The research aims to evaluate the quality of biodiesel based on the SNI 7182:2015 standard, considering parameters such as Free Fatty Acid (FFA), acid value, density, water content, and viscosity through experimental processes involving sulfuric acid esterification and basic catalyst transesterification. The study is expected to provide information on the potential of biodiesel as a vehicle fuel and energy source for colt diesel engines, along with an emission analysis during the transition from biodiesel to solar. The biodiesel produced meets the standards for FFA (0.26%), acid value (0.57 mg/KOH), and density (0.871 g/ml). The waste volume of 490 m3/day generates 5,096 liters/day of biodiesel, sufficient for 23 units of colt diesel engines with 55% efficiency, producing an energy output of 988,902.91 J. The transition to biodiesel fuel can reduce CO2 emissions by 20.4%, NOx by 50%, and HC by 40%.Keywords – Biodiesel, POME, Renewable Energy, Esterification
