Abstract

The goal of the research is to find out how happy people are with Bima Kota's prepaid and postpaid energy services. Quantitative methods are used in this study. The data used is primary data, which comes from giving surveys to the people being studied. All the people who use energy in the Nitu Village in Kota Bima are included in this study. Cluster random sampling is used to get the sample data, and there are 100 people in the group. The results of the study show that 1) Tangibles, Reliability, Responsiveness, Assurance, and Empathy variables have an effect on people who use prepaid electricity services where people are satisfied with the services provided; 2) Tangibles, Reliability, Responsiveness, Assurance, and empathy variables have an effect on people who use postpaid electricity services where people are satisfied with the services provided; and 3) the dimensions of tangibles, reliability, responsiveness, confidence, and emphasis So that means there is a difference in how happy people are with prepaid electricity versus postpaid energy. As for the confidence dimension, it has a t count > t table or a prob value > alpha 0.05, which means that there is no significant difference between respondents who paid for their electricity in advance and those who paid for it later. The positive mean difference means that the average satisfaction of people who paid for their electricity in advance is better than that of people who paid for their electricity later.

Abstract

This study aims to develop and evaluate a fingerprint-based student attendance application using the FPM10A sensor integrated with Arduino and a PHP–MySQL web system at SMK Negeri 2 Luwu. The research employed a Research and Development approach with a waterfall model, and the application quality was assessed based on ISO/IEC 25010 standards covering functional suitability, usability, portability, and maintainability. Data were collected through observation, interviews, questionnaires, and documentation. The results show that all designed functions were successfully implemented, achieving full functional suitability. Usability testing involving 25 teachers yielded a score of 89.8%, categorized as excellent. The application also operated successfully across multiple browsers, confirming its portability, and demonstrated consistent maintainability through simplicity and error-handling features. The novelty of this research lies in integrating FPM10A–Arduino hardware with a lightweight web application and validating it comprehensively using ISO/IEC 25010 quality characteristics within the vocational school context. The findings contribute to improving attendance efficiency and accuracy while promoting digital transformation in school administration. Future work should include biometric performance metrics (FAR, FRR, EER), mobile platform testing, and security evaluation for biometric data protection.
