Abstract

This research analyzes how the reflection of sunlight intensity affects the power generated by a 100WP monocrystalline solar panel with the addition of various reflector tilt angles. An experimental method was used to conduct this analysis by comparing three tests: a solar panel without a reflector, with a 60° angled reflector, and with a 75° angled reflector. Data was collected at one-hour intervals from 09:00 to 16:00 WIB, measuring parameters such as temperature, intensity, voltage, current, and power. The results showed that the addition of a flat mirror reflector significantly improved the performance of the solar panel. With a 75° tilt angle, the total power generated was 373.32W, compared to the total power generated at 60° of 366.93W and without a reflector of 208.62W. The highest power peak was achieved at 13:00 WIB with the 75° reflector at 69.31W. This research demonstrates that a reflector tilt angle of 75° is the most optimal for increasing the efficiency of monocrystalline solar panels as it distributes sunlight more evenly across the panel surface. The recommendation for future research is the utilization of software-based simulations and IoT integration for real-time monitoring, to strengthen experimental data validation and expand the application of this technology at both industrial and household scales.

Abstract

Gondola is one of the facilities used in high-rise buildings that are used to access the outside of the building. Gondola has a maximum load limit that is safe to transport it. Gondola is also often damaged in the cage caused by collisions on the side of the building. Until now, the gondola control still uses buttons which also often experience problems. This study aims to provide monitoring of the cage load and provide information about the distance of the cage to surrounding objects. Gondola control through an android application also includes this research in order to provide an alternative if the buttons on the gondola control experience problems. The short-term goal of this research is to carry out an innovation in the gondola field by conducting experiments through prototypes. The medium term goal is to apply the results of this research into a gondola. The results of this study control and monitoring can function properly even though the results produced are not yet accurate due to the imperfect quality of components, materials and assembly.

Abstract

Turn ratio test is a comparison test of the number of secondary turns with the primary turns on the transformer. The turns ratio and group vector testing is one of the routine transformer tests. This test generally uses the Transformer Turns Ratio (TTR) test tool, the test equipment used sometimes experiences technical and non-technical problems so a comparative test method is needed to get a good analysis. The research method used is observational research and literature study, namely analyzing the transformer to be studied by conducting TTR testing in two ways, namely testing with test equipment and three-phase low voltage sources, aiming to obtain a very good level of accuracy. The test results were analyzed and compared with theory and calculations, with reference to the IEC 60076-1 standard. The results of the comparison of windings and group vectors using TTR 100 test equipment and a 3-phase low voltage source (TVR) show the same conclusions as the results of the analysis, where the first transformer sample is in normal condition and meets the requirements. SPLN D3.002-1:2007 or IEC Standard 60076-1. While the second sample transformer is in an abnormal condition in the W winding where the difference value is above 0.5%.

Abstract

Conventional transportation methods result in the release of harmful greenhouse gases into the environment. Electric vehicles offer an alternative to mitigate this environmental harm. Electric Vehicle Charging Stations (EVCS) are crucial infrastructure components for supporting electric vehicles.  Photovoltaics represents a facet that can be integrated into EVCS to improve eco-friendly power generation. Various factors, including temperature, humidity, and light intensity, influence electricity generation in photovoltaic (PV) systems. This research examines the consequences of temperature, humidity, and light intensity fluctuations within EVCS. During the system integration testing conducted between 09:00 and 16:00, it was noted that there is an inverse relationship between air humidity and temperature; when air humidity increases, temperature decreases, and vice versa. The solar panel exhibits its highest sunlight intensity reception between 09:30 and 15:30. The peak power output from the solar panel was registered at 13:00, with an air temperature of 40.40 °C, air humidity at 35%, and light intensity at 54.61 Cd, resulting in a solar panel power output of 146.1 Watts. Conversely, the lowest power output from the solar panel was observed at 16:00, with an air temperature of 31.80 °C, air humidity at 54%, and light intensity at 39.39 Cd, leading to a solar panel power output of 107.36 Watts. Anticipated findings from these analyses are expected to contribute to future technological advancements, enabling the creation of competitive products in the market.

Abstract

Fire is a disaster that is often encountered throughout the year. This research aims to protect and mitigate the worst possibility of a fire disaster. A PLC automatically creates the work system of this tool, using it as the controller. This tool utilizes two sensors: a smoke detector and a heat detector. Two smoke detectors and one heat detector automatically make the system, each providing input to the PLC. The system splits into two parts: Alarms 1 and 2. If any of the three sensors send input to the PLC, Alarm 1 triggers a buzzer and a yellow light. Alarm 2 occurs if 2 or 3 sensors provide input to the PLC and provide output as the bell lights up, the flash lights up, and the solenoid opens to release Co2 into the room.

Abstract

Currently, Indonesia's energy is running out andhas received serious attention so the Government targets thatby 2050 the role of renewable energy will be at least 31%. Thisencourages the production of various alternative energysources that are environmentally friendly and available, suchas solar power plants. However, solar intensity and a dynamicenvironment strongly influence the output power generated bysolar panels. So in this research, an asynchronous buckconverter design using MPPT will be made to track themaximum power point of solar panels with the fuzzy logiccontroller method which will be applied to Monocrystallinesolar panels with a capacity of 300WP. Fuzzy MPPT will adjustthe duty cycle by PWM Arduino Nano on the asynchronousbuck converter to keep reaching the maximum power point.The results show that the developed system can increase powerconversion efficiency and maintain output voltage stabilityunder various operational conditions. The implementation ofFLC as MPPT on Asynchronous Buck Converter successfullyoptimizes the power absorbed from solar panels, thussupporting the reduction of electrical energy consumption fromPLN in the Jakarta Global University student associationsecretariat building. This implementation is expected to be areference for the implementation of a smarter and moresustainable energy management system in the future.

Abstract

ABSTRACTFuel Oil (BBM) is one of the fuels that have been used to drive most of vehicles such as motorcycles. The authors did the research on motorcycles using electrical energy to be more environmentally friendly. Experiments were done by using the direct test method and analyzing the obtained data to determine how much power was released and how much battery capacity was used to drive an electric motorcycle with variations of the driver's weight as much 60 Kg, 90 Kg, and 125 Kg and speed variations such as 10 Km/Hour, 20 Km/Hour, 30 Km/Hour, and 38 Km/Hour. The experimental results shows that the greater the weight and the speed of the motorcycle, the greater the power and capacity of the battery, so that could be concluded that the use of the battery on the motorcycle becomes more wasteful and the battery life will be shorter.ABSTRAKBahan Bakar Minyak (BBM) menjadi salah satu bahan bakar yang digunakan untuk menggerakkan kendaraan seperti sepeda motor.

Abstract

The use of the 4–20 mA analog signal remains a foundational standard in industrial measurement and control systems, despite the continuous advancement of digital communication technologies. This study implements a hybrid validation approach that integrates the conventional 4–20 mA analog signal with HART (Highway Addressable Remote Transducer) digital communication for conducting Input/Output (I/O) loop testing on pressure transmitters. The primary objective is to ensure the accuracy and reliability of signal transmission from field instruments to control systems such as Programmable Logic Controllers (PLCs) or Flow Computers. Utilizing a HART modem and FieldMate software, analog signals are injected and digitally monitored to verify transmitter output against predefined tolerance standards. Test results indicate that all evaluated transmitters maintained an error level below the 0.25% threshold, in compliance with standards set by the Directorate of Metrology and ASTM/API guidelines. The integration of HART communication significantly enhances testing efficiency, diagnostic capability, and remote configuration flexibility, underscoring the critical role of hybrid validation approaches in modern industrial instrumentation systems
