Abstract

This paper focuses on addressing the challenge of monitoring water reservoirs located at high altitudes where direct inspection of water conditions is difficult. To tackle this issue, the research employs a system for real-time control and monitoring. Specifically, the system utilizes a waterflow sensor to measure water flow, an ultrasonic sensor to determine water levels, and a TDS sensor to detect water turbidity. These sensors are connected to an Arduino Atmega 2560. The control logic for filling the reservoir with water is implemented using the Mamdani type fuzzy logic method, which incorporates rules based on water level readings. Moreover, the study integrates IoT (Internet of Things) technology to enable remote monitoring of water levels and turbidity via smartphones. The study's results demonstrate that IoT technology greatly facilitates real-time remote monitoring of reservoir conditions. The trial data indicate an impressive 97% success rate in controlling the water filling process, with an average error of less than 15%. This successful approach can be applied effectively to create a smart home water reservoir control and monitoring system.

Abstract

For farmers, good quality and clean rice is their selling point. Automatic rice threshing machines are a new breakthrough that can be offered to them. This machine has adopted energy-saving technology and is very practical in operation. One of the technologies is a filterization system, this system is a separator between clean rice and rice grain, so that the quality of the clean rice produced will increase. By controlling the motor speed in this system, less power is used so it will be more energy efficient. This system is supported by other devices in the form of a Proximity Sensor, ATmega 2560 Microcontroller and Dimmer. So this system runs automatically based on the falling rice debit.

Abstract

The high-voltage electrical energy distribution system plays a crucial role in delivering electrical energy from generators to distribution or customers. This high-voltage distribution process starts from 30 kV to 150 kV. The transmission network connecting the Maninjau Substation and Padang Luar Substation uses bare conductors in its distribution. The use of bare conductors causes this transmission network to experience external disturbances. A reliable protection system is essential, so that if a disturbance occurs, it can be quickly detected and quickly isolated or removed from the disturbance current. The role of the protection system in providing signals or command input to the PMT greatly influences the PMT's performance. The PMT's role is also very vital, because the PMT must be able to operate when a disturbance occurs, whether under load or not. Therefore, PMT maintenance needs to be carried out periodically to prevent PMT failures. One of the causes of PMT failures is a low SF6 value, a high simultaneity value, a high contact resistance value, and others. High contact resistance in PMTs also significantly affects network losses. This research was conducted to examine how much the contact resistance value influences losses in the network and PMT performance, how much influence the PMT simultaneity has in isolating the presence of disturbances.
