Abstract

Private schools need help in handling school fees and financial processes. Traditional manual payment systems result in data processing issues, delayed financial reporting, and complications from misplaced records. Late fee payments threaten school income, which is crucial for staff salaries. Modern solutions are imperative. Desktop applications have limitations, requiring installation on specific devices, leading to compatibility concerns. This research opts for a web-based application. It employs prototyping models and predictive abilities using the Naïve Bayes algorithm. The web-based application aims to streamline fee management and predict payment delays, enhancing financial transaction management while prioritizing data security through database encryption. This web-based solution aligns with private schools' operational needs, simplifying payments and increasing late payment prediction accuracy. Extensive black-box testing validated its suitability, satisfying administrative staff needs. Four test cases gained administrative team approval. This innovation empowers private schools to optimize operations and financial management. In summary, the research tackles critical financial challenges private schools face by introducing a web-based application that simplifies payment processes, enhances accuracy in predicting late payments, and aligns seamlessly with administrative needs.

Abstract

The ability to transform data is essential to support strategic decision-making in a company or organization. Data transformation can be done by utilizing data warehouse technology. Therefore, it is necessary to know the description of data warehouses that use the Extract, Transform, and Load (ETL) process. This research will focus on implementing Datawarehouse at TechTrove, an e-commerce company using Pentaho Data Integration (PDI). Star Schema organizes data marts and Online Analytical Processing (OLAP) to optimize data warehouse tasks. Business Intelligence (BI) tools are critical in extracting valuable insights and showcasing the platform's analytical capabilities in customer behavior analysis, product evaluation, sales monitoring, and inventory management. This research transformed raw data into a strategic plan to support decisions in E-Commerce companies.

Abstract

The manufacturing industry is a cornerstone of Indonesia's economy, contributing significantly to the nation's GDP and exhibiting consistent growth. The sector's advancement is closely linked with technological innovations, particularly those associated with Industry 4.0, which integrates advanced technologies into production processes. Enterprise Resource Planning (ERP) systems play a pivotal role among these technologies. However, maximizing the potential of ERP systems necessitates robust IT governance, which can be assessed using the COBIT 2019 framework. This research targets the Cardboard Manufacturing Industry, which has not previously undergone an IT governance assessment, primarily due to the lack of a dedicated IT division. The study evaluates the current state of IT governance within the industry, focusing on specific objectives, including APO12 (Manage Risk), BAI09 (Manage Assets), APO14 (Manage Data), and EDM05 (Ensure Stakeholder Engagement). The methodology involves a comprehensive evaluation using the COBIT 2019 framework to identify gaps between the current and desired capability levels. The findings reveal significant discrepancies in IT governance maturity, highlighting improvement areas. Consequently, the study proposes recommendations to bridge these gaps, enhancing overall IT governance. Suggestions for developing customized ERP modules are further provided to support the industry's technological integration and efficiency.
