Abstract

Toko Simarmata is a business engaged in the business of selling daily necessities. The store has quite a lot of customers who come to buy various kinds of needs ranging from snacks, drinks and household supplies. However, the store is in the process of processing its transactions, such as the preparation of goods data which includes prices, and all sales transactions are still manually recorded in the book. This often causes problems such as the loss of sales data which causes re-recording so that the resulting report is not perfect. Therefore, a web programming system is needed which has the aim of making it easier for Simarmata Shop owners to solve the problems that occur, such as storing data on goods sales transactions, knowing sales reports that occur within a certain time frame, consumers who can order the desired items through the website and payments that can be made non-cash without the need to come directly to the store. The design of this Information System is of course based on using direct observation methods and interviews with shop owners. So as to produce a Sales Information System at a web-based Simarmata Store that suits the needs of the store.

Abstract

The trade system can be impacted directly or indirectly by today's rapid technological advancement. We currently only have access to e-commerce via the Internet, which allows us to select the items we want, learn more about them, and conduct business with anyone, regardless of distance or time. If Nasyrul Ilmi bookstore wants to improve the quality and efficiency of its book sales services, it needs to implement information technology. In this context, the author creates a sales information system that is hosted on a website in order to improve the store's operations and broaden its market reach. The goal of this study is to create a bookstore-specific sales information system that is both efficient and useful. Through needs investigation, natural UI configuration, organized data set advancement, and site-based framework execution, these objectives can be accomplished. Customers can buy books online via the store's website thanks to the sales information system. It also helps the store owner manage inventory, process orders, analyze sales, and track shipments. It is anticipated that Nasyrul Ilmi Bookstore will be able to enhance customer service quality, increase market reach, and increase operational efficiency by implementing this system. In addition, the store has a competitive advantage thanks to this system in the digital era's increasingly competitive book sales market.

Abstract

Toko Anarman Store is a toy store that sells various kinds of toys, education, and home decor. This shop still uses a manual system for sales transactions, with the process of selling goods usually still written on notes and then summarized in a sales book. The seller must check each item individually and record the results in a book to determine the number of items in the store. Therefore this web-based Sales Information System is designed to assist the sales process at the store. The purpose of this system is to increase the efficiency and effectiveness of the sales process. This system includes several important features which include product management, supplier management, and report printing. Product management includes adding, deleting, and updating product data available in the store. Printing includes printing sales reports, stock reports, consumer reports, and supplier reports. This information system is made using the Sublime Text 3 application while the programming language uses PHP, Xampp is used to run the web server, MySQL is used for database management.

Abstract

The Lecturer BKD Files Management Application is a system designed to facilitate digital management of Lecturer Tri Dharma (BKD) files. This application aims to simplify the process of recording, archiving and reporting BKD which is often complicated and time consuming if done manually. With features such as file upload, document search, and archive management, this application allows lecturers to easily manage and track various documents related to their BKD. Apart from that, this application also makes it easy for the administration to verify and monitor lecturers' BKD efficiently. The implementation of this system is expected to increase effectiveness and accuracy in BKD management, as well as reduce the administrative burden faced by lecturers and the administration. This research contributes to the academic community by providing a practical tool that enhances the efficiency of BKD management. The application reduces administrative overhead, minimizes errors associated with manual processes, and improves the transparency and accessibility of BKD records. Furthermore, this study offers insights into the challenges and best practices in developing digital solutions for academic administrative tasks, potentially serving as a model for similar initiatives in other educational institutions

Abstract

In the evolving landscape of digital education, Learning Management Systems (LMS) have become pivotal in managing student engagement and academic resources. These platforms not only facilitate course delivery but also log extensive behavioral data, including attendance rates, quiz performances, LMS usage time, and forum activities. Leveraging this data, educators and institutions can enhance academic outcomes through predictive analytics. This study investigates the use of Random Forest Regression, a machine learning technique, to predict student final grades based on LMS behavioral data. A synthetic dataset comprising 100 student records was used, each containing features that reflect engagement and performance. The data underwent standard preprocessing procedures including normalization and partitioning into training and testing sets. The Random Forest model was trained and evaluated using Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE) as performance metrics. The model achieved a MAE of 4.57 and RMSE of 5.90, indicating a high level of predictive accuracy. Feature importance analysis revealed that average quiz score and attendance rate were the most significant predictors, followed by LMS time and forum activity. These findings demonstrate the effectiveness of ensemble learning methods in educational settings and support the integration of predictive systems in LMS platforms for real-time academic monitoring. Such systems could provide early alerts for at-risk students and assist educators in designing targeted interventions. This research contributes to the field of Educational Data Mining by validating the practical utility of Random Forest Regression in supporting personalized and data-driven learning strategies.
