2025-06-19T09:08:11+07:00

The rapid development of technology has brought significant changes in various aspects of life, including metrology, which is essential to ensure the accuracy of measuring instruments in commerce, health, public safety, and the environment. To maintain the standard and quality of measurement, an efficient and timely monitoring and investigation system is needed. This research aims to develop an Android-based application to support legal metrology investigations, in order to improve accuracy, efficiency, and transparency in the management of measurement data. The case study was conducted at the Metrology Division Office of the Trade and Industry Office of Jombang Regency, which handles measurement standardization and supervision of measuring instruments. This application is designed to address the issues of measurement inaccuracies, insufficient calibration frequency, and result recording errors, and help metrology officers overcome challenges in the measurement process. Using the Android platform, the app offers ease of use and customization, and improves performance, speeds up the investigation process, and encourages innovation in the field of legal metrology.

This research is motivated by the suboptimal management of infrastructure and facilities at SMK Sehat Insan Perjuangan (SMK SIP), which is still carried out manually and causes various problems such as data loss, difficulty in tracking borrowing history, and delays in reporting processes. The purpose of this research is to design and build a web-based infrastructure and facilities information system to facilitate data collection, borrowing, returning, and reporting of school assets more efficiently and accurately. The development method used is prototype with stages of requirements gathering, prototype creation, user evaluation, to iterative system improvement. The system is built using the CodeIgniter 4 framework, PHP programming language, and MySQL database, and equipped with a user-friendly interface. The system has been tested using the black-box testing method and shows that all features function properly, including login features, facility data management, borrowing records, and maintenance schedules. The implementation results show that this system can improve efficiency and accuracy in managing school facilities and simplify administration that was previously done manually.
