Abstract

Abstract— Factors that influence comfort on trains are thermal comfort factors. Thermal comfort is a thermal interaction between humans and their surroundings that satisfies the human mind. The principle of thermal comfort itself is related to the surrounding body temperature. Because if the human body temperature and the environment have a significant temperature difference, discomfort will occur. Research aims to design an effective air conditioning system to produce a better air supply so that it can overcome the problem of thermal comfort in trains. The first methodology for this research was collecting primary and secondary data. Primary data includes data on train size, construction, type of equipment, and number of passengers. While secondary data is data on design conditions. To determine the value of the cooling load, it is necessary to analyze the heat load in the train which includes sensible heat load and latent heat load. The results of this research obtained a total sensible heat value of 86371.19 Btu/hr. And the total latent heat is 73855.839 Btu/hr. Based on the results of research that has been carried out, it can be Conclusions were drawn from the calculation of the cooling load on the Type K3-438 Passenger Train with a capacity of 94 passengers. It was concluded that the minimum cooling load required was 40412.48 kcal/hr. Keywords: Cooling Load, Thermal Comfort, Passenger Train, Thermodynamic Physics

Abstract

This research presents the design and testing of an automatic color detection system using TCS3200 color sensor integrated with Arduino Uno microcontroller. The system was developed and tested using Wokwi virtual simulation platform before physical implementation. The TCS3200 sensor converts RGB light intensity reflected from objects into frequency signals, which are processed by Arduino Uno to classify colors into red, green, and blue categories. The system incorporates audio feedback using DFPlayer Mini module to provide sound notifications for detected colors. Testing results show that the system can accurately detect and classify primary colors with frequency-based thresholds: red (R<48 &R>37 & G<95 & G>85), blue (G<75 & G>65 & B<33 & B>23), and green (R<55 & R>40 & B<25 & B>5). The simulation validation demonstrates stable performance with consistent color recognition capabilities, making it suitable for industrial sorting applications and assistive technology for visually impaired individuals.

Abstract

The Gas and Steam Power Plant (PLTGU) utilizes exhaust heat from gas turbines to produce steam, which is then used to drive steam turbines. One of the critical processes in this system is seawater desalination, which requires reliable measuring instruments to ensure the continuity and quality of the water supply. The Differential Pressure Flow Transmitter type Azbil JTD920S is used to measure fluid flow rates at four main points: Sea Water Flow (feed), Distillate Water Flow, Condensate Water Flow, and Sea Water to Ejector Condenser Flow. A decline in transmitter performance may occur due to environmental factors, corrosion, and high workload, making periodic preventive maintenance (PM) essential. This study aims to analyze the transmitter’s performance by comparing PM data with the manufacturer’s maximum specifications using literature studies, direct observation, and interviews. The calculation results show that the highest performance levels are found in the Distillate Water Flow (73.53%) and Sea Water to Ejector Condenser Flow (73.87%) lines, while the lowest is in the Condensate Water Flow (49.00%). These findings emphasize the importance of close monitoring of high-performance transmitters to prevent premature failure and maintain the efficiency of the desalination process.

Abstract

This research focuses on analyzing the performance of a vacuum pan automation sistem using solenoid valves at PT. Duta Sugar International as an effort to improve the efficiency and quality of refined sugar production. The vacuum pan is the main tool in the sugar crystallization process that functions to evaporate the sugar solution under low pressure. Problems faced in the manual sistem are temperature instability and high dependence on operators, which impact time inefficiency and decrease product quality. The purpose of this research is to design and analyze the implementation of an automatic control system based on a Distributed Control Sistem (DCS) with the integration of solenoid valve actuators to optimize temperature stability and cooking process efficiency. The research method was carried out using qualitative and quantitative approaches through direct observation, technical interviews with the automation team, and supporting literature studies. The results showed that the automatic system was able to maintain a stable cooking temperature in the range of 78°C–85°C, lower and more efficient than the manual system which fluctuates between 90°C–100°C. In addition, cooking time was reduced by 10–15 minutes per cycle, and the crystallization process became more uniform with more efficient energy consumption. The results showed that the implementation of DCS-based automatic control with solenoid valves significantly improved operational stability, productivity, and energy efficiency. Thus, this automation sistem proved to be an effective solution for optimizing vacuum pan performance in the modern sugar industry.

Abstract

The industrial world, particularly the petrochemical industry, is currently experiencing significant growth and advancement. With this rapid development, companies need to pay close attention to the equipment used in the production process, one of which is the boiler. Boiler is one of the main components in the petrochemical plant, as it serves as the equipment responsible for generating steam. Over time, the boiler’s performance will naturally decline due to continuous operation. Therefore, it is necessary to apply a method to evaluate the boiler’s performance. The performance of a boiler is represented by its efficiency value. This value is essential to determine how effectively the boiler produces steam. The higher the efficiency, the better the boiler’s performance. The boiler at the petrochemical plant under study is of the fire tube type. The boiler efficiency analysis in this study was carried out using the input-output method, also known as the direct method. The analysis was performed by comparing the energy obtained from the working fluid (water and steam) with the energy contained in the boiler fuel, represented by the Gross Calorific Value (GCV). Based on the analysis, the highest boiler efficiency was obtained on August 11, 2025, at 65.326858%, due to the high steam temperature of 224.0875°C. Meanwhile, the lowest efficiency was recorded on August 8, 2025, at 45.810117%, which occurred because the boiler had just restarted after a seven-day shutdown.

Abstract

This study evaluates the consistency of transmitter level performance through calibration data obtained from the Instrumentation Maintenance Unit of the Cilegon PLTGU. The purpose of this study is to determine the accuracy, linearity, and stability of transmitter output against standard reference values. Qualitative methods were used, including direct observation, interviews, and literature studies to support the analysis of calibration procedures. Calibration data from the Masoneilan 12420-51 and Yokogawa EJA210E transmitters were analyzed using a comparative approach between normal and abnormal calibration results. Classification was based on the difference between the actual output and the 4–20 mA standard signal, with a tolerance limit of ±0.25% in accordance with ISA and IEC calibration standards. The results of the study show that the Level-3 Deaerator Storage Tank transmitter operates within the normal range, with excellent linearity and accuracy, while the Flash ST Tank Level transmitter shows minor deviations outside the tolerance limit, categorized as abnormal. These deviations suggest the potential for drift or zero shift influenced by environmental factors and aging. This study concludes that periodic calibration is necessary to maintain tranmitter performance reliability and ensure accurate signal transmission in the automatic control system at the Cilegon PLTGU facility.
