Abstract

Regarding the importance of using fan motors in various industrial applications, such as ventilation systems and air conditioning systems. 3 Phase AC Fan Motor is one of the most frequently used components in HVAC systems because it has high reliability and efficiency in the use of electric power. However, in operation, a 3-phase AC fan motor requires speed control according to system requirements. Therefore, an appropriate and effective fan motor speed control system is needed. Variable Speed Drive VSD is an effective solution to control the speed of a 3-phase AC fan motor. Variable Speed Drive VSD is able to control the speed of the motor by adjusting the frequency given to the motor. In this research, a Variable Speed Drive VSD control panel will be designed and built to control the speed of a 3-phase AC fan motor. The test results were carried out after using the VSD control panel by setting the potentiometer for 6 conditions, namely when the frequency was set at 50 Hz, 45 Hz, 40 Hz, 35 Hz, 30 Hz, 25 Hz, the resulting rotation was 1449.5 RPM, 1347 RPM, 1206 RPM, 1059.2 RPM, 911.8 RPM, 764.4 RPM and the sound generated is 79.7 dB, 76.0 dB, 72.2 dB, 71.0 dB, 69.9 dB, 67.7 dB. By using the VSD control panel, the rotation of the 3-phase motor can be adjusted and adjusted according to the needs of the system, so that later it will have an impact on reducing sound levels and increasing user comfort.

Abstract

This study is an option for the safety system of residential electrical installations from the danger of electrical disturbances such as overloads, short circuits and electric shocks that can endanger our safety. Residual Current Breaker with Overcurrent Protection is a combined component of the MCB and ELCB that stops the flow of electricity when an overload, short circuit, or leakage current occurs. Therefore, the author presents the function of RCBO in this study and the research flow is also explained in this study. The In magnitude of the RCBO installed was In = 6 Ampere in this study with high sensitivity (30 mA). After RCBO testing is carried out on the overload used with In 6 Ampere with high sensitivity of 30 mA, the RCBO will be tested with a load current of 9.04 Ampere, then the RCBO will be trif. At the time of a short connection with a load power of about 800 Watts the RCBO trives, and an electric shock with a load of about 800 Watts the RCBO trif, and an electric shock with a load of about 800 Watts RCBO experienced a trif. To determine the rating magnitude of RCBO current (In), from the results of the current calculation at the load, which is 5.34 Ampere, RCBO with In = 6 Ampere is chosen because there is no RCBO that has a nominal current value of 5 Ampere.

Abstract

Geographically Indonesia as a tropical country located on the equator and is a maritime continent with a vast sea, relatively high rainfall causes relatively high air humidity, this causes lightning clouds containing electric charges to form very easily with destructive properties, seeing some of the damage that usually arises due to lightning strikes, then an effort to overcome the strike is known as lightning protection. In this type of research, a type of quantitative research is carried out with the processing and calculation of output data from observations including multi-storey building data, thunder days, specifications and types of lightning rods, lightning current conductors, and grounding systems with standard criteria based on the 1983 General Lightning Installation Regulations (PUIPP) and SNI 03-7015-2004. estimated risk of lightning strikes index value of 22, average annual strike frequency of 2.43 strikes and lightning strike efficiency value of 0.96 protection level I. minimum cross-sectional area 22.5 mm. Minimum cross-sectional area of 22.5 mm2, 2x35 mm2 coaxial cable installed and the total resistance value of multiple ground rod electrodes of 1.04Ω, a maximum of 2.5Ω is in accordance with the standard and in the air termination with the calculation of the radius of the rolling ball with a radius of 20 m lightning strikes each end of the building side are still exposed to the touch of the rolling ball. Because the air termination installed is conventional type, the calculation of air termination with electrostatic lightning rod protection Angle a is ∠42.06º with a lightning strike distance to the building as high as 134.15 m. Therefore, optimization is carried out using an electrostatic type lightning rod Flash Vectron FV6 brand with a radius of 140 m.

Abstract

In industrial processes, steam is widely used for heating, drying, and sterilization. However, manual or on–off steam control often leads to energy waste and unstable temperature. This study designs and implements an automatic control system using an RTD PT100 sensor, temperature transmitter, PLC (M221), and modutrol valve. A PID algorithm was applied to proportionally adjust the valve opening according to the actual temperature. The results showed that the system maintained a maximum deviation of ±2 °C from the 160 °C setpoint with a response time of less than 10 seconds. Steam consumption decreased significantly from 4,029 tons (January 2024) to 2,368 tons (May 2025), equivalent to about 41.24% savings. The estimated cost savings range from IDR 332 million to IDR 581 million per month. The system proved effective in improving thermal stability, energy efficiency, and reducing operator workload.

Abstract

The rapid advancement of technology has made daily life more efficient and practical. Technology has begun to replace conventional parking methods that lack real-time information and are prone to human error. This study introduces a smart parking system innovation based on the ESP32 microcontroller as a solution to the limitations of conventional parking systems that are unable to provide accurate real-time information. The objective of this research is to design and test an ESP32based smart parking system capable of providing real-time and precise information on parking slot availability. The method employed is prototype engineering with a descriptive approach, which includes device design, component testing, and documentation. The test results show that the smart parking system works optimally and responsively. Infrared sensors are able to detect vehicles and activate servo motors that operate for 5 seconds. The LCD displays real-time parking information, while ultrasonic sensors provide accurate readings at distances of ≤15 cm. A red LED lights up as an indicator when a parking slot is occupied (distance <15 cm), while a green LED lights up when the slot is available (distance >15 cm). Integration with ThingSpeak and ThinkView applications runs smoothly with a fast update interval of approximately ±15 seconds, and the ESP32-CAM successfully records vehicles entering and exiting with clear results. Component power consumption is stable, with voltage and current measurements in line with their functions: the infrared sensor recorded an average voltage of 3.7 V without load and 0.15–0.16 V with load, with currents ranging from 3.7–4.1 mA without load to 7–9 mA with load. The SG90 servo motor maintained a stable voltage of around 4.9 V both with and without load, while current increased from 2.7–2.8 mA to 1213 mA during operation. In conclusion, the ESP32-based smart parking system has proven effective in providing real-time parking information, with recommendations for large-scale implementation and the addition of a license plate recognition feature to further enhance functionality.
