Abstract

A remote temperature monitoring system has been created in the server room using LoRa technology which is based on preventing overheating on servers which can affect the performance of components in the server. The research objective is to design and implement a new LoRa-based server room monitoring system design. The targets of this research are (a) creating a system prototype, (b) programming the system with the help of Arduino IDE, (c) measuring system performance. The research method starts from making a prototype and measuring system performance. The results of system performance measurements, testing on LoRa showed the best RSSI results of -56 dBm, temperature data from 17°C -19°C and humidity from 55% to 59% in the server room. Overall the tool can function well.

Abstract

Electrical energy consumption in the household sector is frequently uncontrolled, particularly when electronic devices are used. That is the tendency of users to forget to turn off or unplug the electronic device from the socket. In that case, modifications are made to the socket so that it can be controlled remotely via a smartphone. The hardware design uses the NodeMCU ESP8266 as a microcontroller combined with the PZEM-004T sensor module for electrical magnitude. Relay modules are used to secure the circuit in cases of higher loads. So that in the system, all three sockets can be monitored simultaneously. While the software design uses MIT App Inventor and Thingspeak Platform as servers. The data is saved in CSV format, which can be converted to Google Sheets or Microsoft Excel. Data is stored in the form of the name of the electronic equipment, the time of use, as well as voltage, current, power, cos phi, and electrical energy used. So that users can regulate the use of electrical equipment at home and reduce the waste of electrical energy. The test results showed the average faults for voltage, current, power, cos phi, and energy were 0.06%, 5.32%, 5.67%, 0.7%, and 7%, respectively.

Abstract

Milk is one of the foods that contain a number of highly nutritious nutrients. The content of protein, glucose, lipids, mineral salts, and vitamins with a pH of 6.8 causes microorganisms to grow easily in milk. Microorganisms that develop in milk will cause the milk to spoil. Therefore, it is necessary to process milk in order to maximize the quality and durability of milk, one of which is by heating milk (pasteurization). The pasteurization device is designed using a MAX6675 thermocouple sensor to measure the temperature of the milk during the pasteurization process where the temperature is controlled by a PID (Proportional Integral Derivative) controller with predetermined Kp, Ki, Kd parameters. The parameters obtained for PID control are Kp = 42, Ki = 3.5, Kd = 9. In testing the pasteurization device applying the High Temperature Short Time (HTST) method with a setpoint of 72 ℃ for 15 seconds with the time needed to reach the setpoint value for 29 minutes. Temperature readings using MAX6675 thermocouple sensors produce an average error of 0.5% when compared to national standard measuring instruments. Pasteurized milk can last for 3 days at 4-10℃ and for 4 hours at room temperature or around 21-25℃.
