Abstract

This research focuses on designing an automatic chicken feeding device based on Arduino Uno which is designed to increase efficiency and regularity in feeding. This system uses an Arduino Uno as a controller, a servo motor for the feeding mechanism, an infrared sensor to detect the presence of feed, and an I2C LCD to display status and monitoring data. When the sensor detects the feed bin is empty, the servo motor is activated to open, fill the feed, and close the feed bin again. Tests show that this system is able to manage feeding 500 grams of feed to the silo well. The average feed spilled when the servo motor is open is 42.75 grams at a 30° angle, 84.75 grams at a 45° angle, 100 grams at a 65° angle, and 177.75 grams at a 90° angle. This system reduces human involvement and ensures feed is provided evenly and regularly. The infrared sensor has high accuracy, and the servo motor functions well in the feeding mechanism. In addition, feed status can be monitored in real-time via LCD and Serial Monitor. In conclusion, this tool is effective for increasing the productivity and efficiency of chicken farming. Further development is suggested for IoT integration and adaptation for different types of poultry as well as environmental conditions.

Abstract

Electric switches are vital components in railway signaling systems, responsible for directing train tracks. At Jakartakota Station, single electric switches are prone to disturbances caused by high reverse voltage, which can blow 4 A fuses and halt operations. Based on this issue, this study analyzes the effect of using a 10 Ohm 100Watt resistor as a reverse voltage suppression solution. The title was chosen to reflect the specific component specifications, the type of switch system studied, and the precise research location, ensuring a clear research focus. The methodology included measuring current and voltage before and after resistor installation, analyzing system performance under both normal and obstructed conditions, and evaluating effectiveness without major modifications to indoor systems. The results show that installing the resistor reduced detection current from 4.1 A to 1.9 A, preventing fuse failures. Detection voltage remained within the relay’s operating range, while power voltage was unaffected. Compared to previous studies, the novelty of this research lies in its direct testing within an active operational environment, the use of resistor specifications tailored for high-current loads and outdoor conditions, and a practical approach that can be implemented without overhauling the entire system design. Thus, the use of a 10 Ohm 100Watt resistor is proven effective in enhancing the stability and reliability of electric switch systems, extending component lifespan, and supporting operational safety in Indonesia’s railway sector.

Abstract

In industrial manufacturing, electricity is one of the most critical resources for sustaining operations, particularly production activities. Therefore, electrical systems must remain in optimal condition, ideally operating continuously without interruption. Proper maintenance and periodic monitoring are essential to ensure reliability. Failures in production machinery often arise from multiple factors, not only disturbances in the power supply but also external interferences such as animals.. To address these challenges, a Three-Phase Current and Voltage Monitoring Device was developed to facilitate real-time monitoring of all production panels without requiring direct on-site inspection, thereby improving time efficiency. The system employs a NodeMCU microcontroller integrated with a PZEM-004T sensor, utilizing an IoT-based platform via Blynk. The measurement error achieved is approximately 0.54%. The advantage of this monitoring tool lies in its ability to identify the cause of phase trips when the flowing current exceeds the protection settings, thereby simplifying the analysis of disturbances and enhancing overall system reliability.

Abstract

Indonesia has targeted a 31.89% reduction in greenhouse gas emissions through its own efforts and up to 43.20% with international support by 2030. One of the main strategies in achieving this target is through ecosystem restoration, particularly forests and peatlands, which play a crucial role in carbon sequestration. However, restoration efforts still face challenges such as limited field data, delays in detecting ecosystem changes, and minimal technology integration in monitoring. To address these issues, this study proposes the use of an Internet of Things (IoT)-based monitoring system and smart sensors as an innovative solution. The research method used was a Literature Review, a research approach based on the collection, evaluation, and synthesis of various relevant scientific works to build a conceptual understanding of a topic. The results indicated that IoT implementation in Indonesia faces significant challenges, with network infrastructure in remote areas, limited implementation costs, uneven technical skills, and data security issues being the main obstacles. Furthermore, successful implementation requires institutional support, regulations, and local community participation to optimize the use of IoT-based monitoring systems.

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.

Abstract

The condition of the raw water path in the RO (Reverse Osmosis) Magna dispenser which does not close completely towards the membrane when the storage tank is full which results in the membrane producing excess product water and reject water resulting in waste of raw water. The use of a 24 VDC selenoid aims to withstand raw water pressure when the storage tank is full. The purpose of this study was to determine the effect produced after installing a 24 VDC selenoid to the membrane. The techniques used in this research are observation and interviews. The function of the 24 VDC selenoid is to hold water in the raw water line that will enter the membrane. The results showed that there was no excessive discharge of reject water when the storage tank was full. From the results of the study it was found that when using a Automatic Shut Off Valve as a water retainer produced as much as 180 ml of reject water per minute, then when using a selenoid as a water retainer, it produced 0 ml of reject water per minute. The use of selenoids to replace the role of Automatic Shut Off Valve as water retainers when the storage tank conditions are full can be said to be successful because the membrane no longer gets raw water pressure. For the next step, you can test similar tools to get comparable and optimal results.
