The follow-up process of examination results at the National Civil Service Agency (BKN) has so far been conducted manually using spreadsheets and physical documents, which has the potential to cause delays in reporting, data duplication, and low monitoring efficiency. This research aims to design and build a monitoring information system for follow-up on examination results as a form of digitalization of the audit process within the BKN. This system is developed using web-based technology, with Laravel as the backend framework, PHP as the main programming language, and MySQL as the database. The development process uses the Waterfall method which includes stages of analysis, system design using UML, implementation, and testing. To ensure the functionality of the system, black box testing is conducted which shows that all main features operate according to user requirements. In addition, the system evaluation was conducted through a user satisfaction questionnaire among several relevant employees at BKN, and achieved a satisfaction level of 87%, indicating a positive acceptance of the developed system. This system enables the recording, monitoring, and reporting of follow-up actions from inspections to be done in a structured, real-time, and well-documented manner, while also supporting increased transparency and accountability within governmental agencies.

This study aims to analyze the influence of variables within the Technology Acceptance Model (TAM) framework, namely Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Attitude Toward Using (ATU), and Behavioral Intention to Use (BI), on the satisfaction of users of the online transportation application InDriver. TAM is a commonly used model in evaluating technology acceptance and is utilized in this research to measure the extent to which users' perceptions of the ease and benefits of using the application affect their satisfaction. Data was collected through a quantitative survey using a questionnaire with 150 respondents who are active InDriver users. The analysis method used is multiple linear regression to test the simultaneous and partial effects of each TAM variable on user satisfaction. The results show that PU and PEOU have a significant effect on attitude and intention to use, which in turn has a positive effect on user satisfaction. This finding indicates that the acceptance of technology directly affects user satisfaction in the use of digital transportation services. This research contributes to application developers and service providers in understanding the factors that influence technology-based user satisfaction.

Web-Based Education Development Contribution Payment Management Application at Islamic Junior High School YAPISMA

Arda Mulya Darmawan — Tue, 17 Jun 2025 00:00:00 +0700

Education serves as a means for individuals to acquire both academic and non-academic knowledge, with institutions providing the environment for teaching and learning processes. Educational fees, such as the Education Development Contribution (SPP), are charged to individuals with the right to learn. However, many institutions, including the YAPISMA Islamic Junior High School, still manage these payments manually. The use of computer technology in data processing is essential to improve efficiency and accuracy. This research aims to develop a user-friendly web-based SPP payment management application for the YAPISMA Islamic Junior High School to enhance administrative processes and improve the quality of educational services and school financial management. The research methods include literature review, observation, and interviews with school administrative staff. The application development follows the Agile model, which encompasses the stages of initial planning, design, development, testing, implementation, review, deployment, and maintenance. The results of the study show that the web-based SPP payment system provides ease and efficiency in both payment processing and student data management, replacing manual methods and reducing errors in financial reporting. With the implementation of this application, significant improvements in administrative efficiency and the quality of educational services at the YAPISMA Islamic Junior High School are expected, and it could serve as a model for other schools.
