Abstract

The ever-growing and increasingly sophisticated weapons technology has led countries to continue to develop automated weapons. Since manual control of the movement and position of the weapon is very difficult to obtain a high degree of accuracy, inaccuracies in firing can cause fatalities. In order to minimize errors and inaccuracies in shooting and facilitate military performance in the use of weapons, automatic weapon drives are required. In this study, a product called ARO-GUN was developed to perform target locking and firing using an MG996R servo-type DC motor. This ARO-GUN product is based on testing when locking and firing has an X-axis accuracy of 98.51% and an average error rate of 1.50% and an average Y-axis accuracy of 97.97% and an average error rate of 1.94%. Based on research and testing, it can be inferred that the ARO-GUN product firing system can facilitate military performance in the use of weapons and minimize fatalities due to errors and inaccuracies in firing.

Abstract

The wasteful behavior of clean water causes more and more people to lose access to clean water. The use of water in households so far is still very difficult to manage in using water effectively. Clean water scarcity is a situation when there is a shortage of water to meet human needs. This study built a Home Water Flow Monitoring (HEROIG) system based on the Internet of Things (IoT) to monitor and control water use at home. The hardware uses NodeMCU as a microcontroller and sends the sensing results of the water flow by the water flow sensor which will be sent to the cloud server. Control can be done through the HEROIG android application which has been created and integrated with the IoT system which must work in a good network connection. Testing the quality of the network connection or Quality of Services (QoS), especially packet loss, uses two parameters, namely time and distance. The results of testing the time parameter packet loss by testing once in six seconds in one minute have an average packet loss value of 1.13%, then for testing the distance parameter with the difference of each distance is four meters has an average packet loss value of 0.15% . The test results show that the quality of sending sensor data to the cloud server has a very good category of QoS packet loss parameters, because it has a packet loss value <3%.

Abstract

Electrical energy is a form of energy that comes from a current source which is usually expressed in Watt hour. The energy used by electrical equipment is the rate at which energy (power) is used for the time the equipment is used. To save the electric power used, consumers must know the electricity consumption every day. To limit usage and estimate electricity usage, therefore consumers must be able to monitor and control the consumption of electric power with a system that is easy and not confusing. One of the current technologies that make monitoring easier is an IoT-based system. PEMoS is a tool designed to monitor and control the consumption of electric power. The device used is equipped with a voltage and current sensor that can read the voltage and current in real time with the NodeMCU communication to send data to the user using the internet network. PEMoS has two parts, namely client and server that communicate wirelessly. The data read by the sensor must first be received by the server before being sent to the cloud server. PEMoS also has an android application which is used to control the client and monitor the electrical power sourced from PLN. After testing the tool, an error value of 1.60% on the voltage sensor reading is obtained, which is still within tolerance limits. For current sensor testing, an error of…. In the communication between the client and the server, there is a delay in sending data for ± 6.

Abstract

Water is an important component in life, but there are still many people who still do not care about the use of water in everyday life. Water use in the household is still very difficult to manage in the use of water effectively. To deal with these problems, of course, a control system is needed that can monitor and control the discharge of water that takes place in real time and programmatically in order to improve the effectiveness of water use. This study developed an Internet of Things (IoT) based Home Water Flow Monitoring (HEROIG) system. The hardware used as the microcontroller of this system is NodeMCU. Water flow sensors are used as sensing resulting from water discharge and servo motors as the main actuator controls on this system. The system is designed using PID control to produce water discharge output according to the user's wishes. Testing of pid control system is done using several experiments input parameter values Kp, Ki and Kd. From the test results that produce the best value when Kp = 1, Ki = 1 and Kd = 0.5. From the design results obtained, also conducted tests on each set point value to produce water discharge output according to user input. The results showed there was still an overshoot condition and had an error value of <14%.

Abstract

This study assesses the health of the T5 transformer oil at the Geothermal Power Plant to enable early thermal-fault diagnosis and support evidence-based maintenance. Methods comprised Dissolved Gas Analysis (DGA) with TDCG evaluation per IEEE C57.104-2019, Duval Triangle mapping, and breakdown-voltage (BV) and water-content testing per IEEE C57.106-2015. Results show TDCG of 686 ppm (Condition 1) with CO₂ at 10,000 ppm; gas fractions CH₄ 70.18%, C₂H₄ 29.24%, and C₂H₂ 0.58% place the point in zone T2 (300–700 °C). Water content is 29 ppm—above the recommended limit for transformers <72.5 kV (good: <10 ppm)—while mean BV is 73.4 kV, exceeding the 40 kV minimum. The evidence indicates a medium-level thermal fault with high moisture contamination. Oil filtering/dehydration and periodic DGA trend monitoring are recommended to mitigate failure risk and inform data-driven maintenance planning
