Abstract

Orbital perturbation refers to the phenomenon where a satellite's orbit undergoes changes due to external influences like variations in Earth's gravitational field, gravitational interactions with the Moon, impacts from meteoroids or other objects, and the pressure exerted by solar radiation. To address these changes and maintain their intended orbits, satellites utilize small onboard thrusters. These thrusters are fired in specific directions to make course corrections, but this action consumes the fuel that the satellite carries from Earth. Over the past three decades, communication satellites have played a crucial role in global communication. In the 1960s, their primary mission was to enable point-to-point transmissions between continents. They achieved this by being positioned in geostationary orbits, which are located just above the equator and allow them to constantly observe approximately one third of the Earth's surface.

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

Based on the results of the research conducted, there were problems found that when the process of checking the depth and turbidity of water quality was still using a manual system that involved the role of employees in carrying out the checking process using a opacimeter and level transmitter. Therefore, researchers provide input and suggestions for the process of checking the depth and turbidity of Water using sensors to get the results of checking and an Internet of Things based system to monitor the results of the sensors used.Then the results of the process can be monitored directly into the website platform. In this research, the writer uses fuzzy logic method to program the hardware and monitoring results use a website with codeigneter framework. Which aims to build a monitoring system for checking the depth and turbidity of water quality automatically using ultrasonic sensors and turbidity sensors.
