It is hoped that clustering can complete the grouping of satisfaction levels of BPJS user commuites in the city of Binjai. There are 400 data from correspondent responses from the community regarding the level of satisfaction in using BPJS Health in the city of Binjai. From the results of trials with 400 data carried out with MATLAB, it was found that group 3, cluster 1, had 244 data, cluster 2 had 69 data, cluster 3 had 87 data, group 4 cluster 1 has 78 data, cluster 2 68 data, cluster 3 has 109 data, group 5 cluster 1 has 63 data, cluster 2 has 63 data, cluster 3 has 145 data, cluster 4 has 24 data, cluster 5 has 100 data.

This research was carried out with the aim of explaining the implementation of a mobile-based legal metrology service system for employees and improving the quality of services for legal metrology at the Jombang Regency Office of Trade and Industry. With this mobile-based legal metrology service application, it can make it easy for employees to see the calibration and re-calibration schedule sent by the central metrology website and employees can send the results of the test and re-calibration directly in real-time without having to come to the metrology office. This research applies the waterfall method in its development, which is a systematic and structured approach involving a series of sequential stages. The results of this research created a mobile-based application for employees of the Jombang Regency Trade and Industry Office.
 
 

This study aims to evaluate the level of user satisfaction with the website of SMAN 1 Wangon by applying the End User Computing Satisfaction (EUCS) method. This method assesses user satisfaction based on five main dimensions: system quality, information quality, service quality, end user, and individual benefits. Data collection was conducted through questionnaires distributed to students, teachers, and administrative staff. The results of the analysis show that overall user satisfaction is in a good category, although there are some aspects that need to be improved, especially in terms of information and service quality. This research is expected to provide suggestions for further development of the school website, in order to improve user experience and support the learning process.

This research aims to analyze time and cost control on the ITC Pole Fiber Optic project managed by PT. LUM uses the Earned Value Management (EVM) method. EVM is an effective method for measuring project performance and progress by combining cost, time and completed work data. This case study uses secondary data obtained from project progress reports and PT financial data. LUM. Analysis is carried out to identify cost variance (CV) and schedule variance (SV) as well as cost performance index (CPI) and schedule performance index (Schedule Performance Index - SPI). The research results show that the ITC Pole Fiber Optic project experienced several deviations from the planned budget and schedule, with CV and SV showing negative values ??at several project stages, indicating cost overruns and delays. The CPI and SPI values ??obtained also provide an overview of the efficiency and effectiveness of project implementation. Based on these findings, several improvement steps are recommended to optimize time and cost control to improve project performance in the future. This research makes an important contribution in providing insight into the application of EVM in fiber optic installation projects and can be used as a reference in managing similar projects in the future.

. ChatGPT is one of the growing innovations in artificial intelligence (AI) technology in the field of education, aiming to assist humans in finding information and completing work efficiently. However, students' lack of understanding of the positive uses and benefits of ChatGPT as a self-learning medium results in low adoption rates and underutilized learning potential. Therefore, this study aims to understand the level of acceptance and the impact that influences students in adopting ChatGPT technology so that it can provide direction and recommendations for schools to increase their self-learning awareness through the utilization of AI.
