Abstract

Pet owners rely on veterinary clinics to meet the healthcare needs of their pets, and yet, many veterinary clinics still manage data using conventional methods without fully utilizing digital information systems. This leads to issues such as repetitive registration, difficulties in obtaining copies of medical records, and challenges in finding nearby veterinary clinics. This research aims to address these problems by designing and developing a mobile web application for a veterinary clinic marketplace. The application consists of two main components. The front-end utilizes the React.js library based on Progressive Web Apps (PWA), while the back-end utilizes the Express.js framework. To ensure the overall functionality of the application, black box testing is conducted by the developer. Through this approach, the application is expected to assist pet owners in searching for and accessing information about veterinary clinics, viewing the services provided, and managing pet medical records digitally and easily. This research contributes to optimizing data management in veterinary clinics and enhancing the experience of pet owners.

Abstract

Public Street Lighting (PJU) is a lighting system designed to provide street lighting at night with the aim of increasing comfort for pedestrians and motorists passing through. However, the obstacles faced regarding PJU lights at this time are that when carrying out monitoring and control officers are still checking and visiting the location of every whereabouts of PJU lights. So that to make it easier for officers to manage PJU lights in this study, they will conduct discussions related to the design and development of hardware that is applied to PJU lights. The methods used in the development of this system are design, development, and testing. To build hardware using components such as ESP32 as a microcontroller, PZEM004Tv30 sensor, DHT22 sensor, IC RTC DS3231, Relay 30 A, IC LM2596 5V, IC AMS1117 3.3V, GSM SIM808 Module and LDR sensor, while for implementing the protocol using the MQTT protocol and Antares as the MQTT platform. The results of tests carried out on each circuit block in hardware such as the DHT22 sensor have an accuracy range of ~0.1 – 0.2, the PZEM004Tv30 sensor has an accuracy range of ~0.3 – 0.5, Regulator IC LM2596 5V and AMS1117 3.3V each has an appropriate output voltage of ~5V and ~3.3V, and the CH340C IC Driver IC can work and read properly.
