Abstract

Study aims to help carry out the use of the function of the speedbump or better known as the speed bump which is often found in Indonesia. The number of vehicles that cross the road with the speedbump installed makes the author want to develop the force generated from the speedbump whether it can produce electrical energy through the piezoelectric effect, from this problem the author took the initiative to create a tool that can generate alternative electrical energy. This tool is made of several main circuits, namely piezoelectric sensors to generate electrical energy, charging control as a means of charging the battery. the battery as a reservoir of power generated from the piezoelectric sensor, LED lights as the output of the power generated by the piezoelectric sensor for street lighting. All assembled into a single unit into a miniature device. Based on the results of experiments that have been carried out by comparing the effectiveness and efficiency of the tool with the results of other similar tools, the difference between the two tests of the tool is not much different and is still at the same limit.

Abstract

This research aims to design and implement a monitoring system for key parameters in the biogas production process, namely temperature, humidity, and pH of cow dung liquid using Internet of Things (IoT) technology. This system is designed to support the efficiency and reliability of the anaerobic fermentation process in a biogas plant digester developed in a livestock environment. A DHT11 sensor is used to measure temperature and humidity, while an analog pH sensor is used to measure the acidity level of the liquid in the digester. All data is transmitted in real time via an ESP8266 module to the ThingSpeak cloud platform, which allows for online data visualization and analysis. Test results show that the system is able to operate stably with an accuracy of ±1°C for temperature, ±3% for humidity, and ±0.2 for pH compared to conventional measuring instruments. This system is expected to assist farmers in continuously monitoring biogas conditions and become the basis for automation of fermentation process control in the future.
