This research presents an effective and efficient solution for tracking pets using Message Queuing Telemetry Transport (MQTT) based on radio GPS. The study creates a device and application capable of monitoring the whereabouts of pets to prevent their loss by displaying the latitude and longitude of the pet's location. This application provides real-time monitoring and exhibits high accuracy, with minimal differences in latitude and longitude compared to both animal tracking applications and Google Maps. The application's update speed is also impressive, with a delay of only 4.25 seconds. By continuously developing and enhancing this technology, it is expected to provide broader benefits to the pet-loving community.

The using of artificial sweeteners in food products is more extending, thus evaluation on how food producersimplemented regulation of artificial sweeteners type, maximum level for use, and admonition on product label isneeded. Information was collected according to explanation that written on product packaging (label) such as:type and artificial sweeteners content, and admonition about using and its side effect that based on regulationstated in SNI 01-993-2004 and Indonesian Government Statement No. 69 Year 1999. The food products thatused as sample was categorized in beverages, confectioneries, chewing gum, and dietary supplement products.The observation result showed that many of food products did not add the sweeteners dosage, admonition aboutthe using and it side effect on the label product. Beside that, there were tendency in using more than onesweetener in one product. As for that, the standard or special regulation that regulates the use of artificialsweeteners combination is necessary.

The development of information technology in this modern era has progressed very rapidly, many ways have been developed to store large amounts of data, one of which is to use a server. A server is a computer system that serves and controls client access that is connected to it. All activities that we do on the internet always involve the server. Servers play a very important role because of their heavy duty to serve clients. Therefore, the server may not experience interference. One of the disturbances that cause a damaged server is the temperature that is too hot so that this tool is made in order to prevent these problems. This tool is made to regulate the temperature and humidity of the server room that exceeds reasonable limits. This tool is made using Arduino Uno as a microcontroller, DHT11 as a temperature and humidity sensor, Ethernet shield as a link to the internet. This tool also uses the Blynk application as monitoring, from the results of reading temperature and humidity sensors on this device can reduce the temperature by 6˚C cooler when the temperature in the room is hot, in this case the tool functions as it should

Machinery is equipment that is absolutely necessary for companies in carrying out the production process. The bottle filling machine is one of the automatic machines that functions to fill liquid products into packaging. In the development of automation systems, of course, here we need a general control device (Universal) that does not require special power in operation. This research aims to get the time needed to fill 250 and 500 ml bottles, design nozzles for bottle filling and make plc program ledder on bottle filling machine. The system design on the Bottle Filling machine so that it can fill and lock the lid automatically by using a controller in the form of a PLC as a full controller of the system. In making ladder diagrams using the 7 gate logic method (gate logic). In wiring diagrams that contain the arrangement of the series of components used, and are intended to facilitate maintenance and repair of electrical systems, wiring diagrams can also speed up fault finding and shorten maintenance time. The structure of the programming algorithm contains the sequence of work processes on each component contained in the machine.

Abstract Ã¢â‚¬â€ Automatic Dependent Surveillance Broadcast (ADS-B) is a surveillance technology that provides information on aircraft in the air in the form of 24 bit ICAO aircraft address, ident or squawk, massage, altitude, nationality, speed, longitude, track and heading. The problem faced now is that surveillance can only be done with a web and android-based application on FlightRadar24 so that if the user wants to display more aircraft information, the user is required to pay a subscription. To overcome this problem, hardware is needed that can receive ADS-B signals with a frequency of 1090 MHz and can translate them into information signals. RTL-SDR is hardware that can receive signals with a frequency range from 25 MHz - 1700 MHz, by applying the Raspberry Pi it is used to configure RTL-SDR as a receiver capable of receiving information from ADS-B signals. To get the maximum reception, an omnidirectional antenna is needed that can receive signals from all directions. With this system, it is expected to make it easier to monitor aircraft in real time and processing ADS-B signal data is determined by the strength and weakness of the signal that can be received by RTL-SDR.

The increasing demand for energy efficiency in the digital era has accelerated the adoption of Internet of Things (IoT)-based technologies in household electricity management. This study presents the design and implementation of an IoT-based real-time electricity monitoring system using the ESP32 microcontroller and PZEM-004T sensor, integrated with the Blynk application for remote access. The system measures voltage, current, power, energy consumption, and cost, displaying data on both an LCD and a mobile interface. Experimental testing involved household appliances such as fans and rice cookers under individual and combined usage, with measurements taken at 15-minute intervals. The results demonstrated strong agreement between theoretical calculations and real-time data, with the measured values slightly higher due to the dynamic nature of electrical loads. The system achieved a low average error rate of 0.17%, with a maximum error of 0.30%. These findings confirm the accuracy and reliability of the system, supporting its potential for enhancing user awareness, improving billing precision, and contributing to sustainable energy use in smart home applications.
