Abstract

This study focuses on designing and building a desktop-based Point of Sales system with inventory management that supports transactions in small businesses, specifically for in this paper, the I.M Store using Visual Studio, VB.NET and MySQL as well as UML. This system is integrated with a barcode scanner and a thermal printer to support sales processing. An iterative software development approach with steps such as: requirements, design and development, testing and evaluation were used to ensure that the system is designed and developed according to the stores documented needs. The system is designed to support three user roles, namely the administrator, cashier, and employee, each with different access rights. The developed application allows the administrator to manage master data and reports as well as backup and restore feature, for cashiers to process sales and return submissions due to buyer complaints to the administrator, and for employees to manage pickup and delivery sales as well as return submissions for problematic products at the store to the administrator. Evaluation results show that the system operates correctly and fulfills the operational needs in Store I.M. This research concludes that a desktop-based POS system can be used to support small business operations

Abstract

The availability of transaction data in culinary SMEs offers opportunities for data-driven decision-making, yet it is often underutilized. This study proposes a Smart Pricing and menu bundling recommendation system for Moon Cafe Batam using data intelligence. The research applies the CRISP-DM framework to analyze historical transaction data from a POS system. The FP-Growth algorithm is used to identify frequent itemsets and association rules that represent customer purchasing patterns. These patterns are combined with Cost of Goods Sold (COGS/HPP) calculations to generate menu bundling and pricing recommendations that consider profitability. The system is implemented as a web-based application using React.js, PHP, and MySQL, and evaluated through black-box testing. The results show that the system can support structured menu bundling analysis and pricing simulations, enabling managers to make more objective and data-driven decisions in culinary SMEs.

Abstract

Pengelolaan aset di SDS Dhamma Sasana masih dilakukan secara konvensional menggunakan buku fisik dan Microsoft Excel yang terpisah, mengakibatkan inkonsistensi data stok dan ketiadaan rekam jejak peminjaman. Penelitian ini bertujuan membangun sistem informasi berbasis web untuk sentralisasi inventaris dan digitalisasi sirkulasi barang. Metode pengembangan menggunakan SDLC model Waterfall dengan arsitektur Frontend React.js, Backend Node.js, dan basis data MySQL, serta diuji menggunakan Black Box Testing. Hasil penelitian berupa aplikasi web yang mengintegrasikan pencatatan aset satu pintu dan menyediakan fitur transaksi peminjaman digital dengan validasi stok otomatis. Disimpulkan bahwa sistem ini efektif mengatasi redundansi data, menjamin akuntabilitas melalui jejak audit digital, dan meningkatkan efisiensi pemantauan aset sekolah secara real-time.

Abstract

Library management at SMP Negeri 31 Batam was previously carried out manually using logbooks, which often caused data inaccuracies, delays in information retrieval, and difficulties in tracking book loans and inventory. This study aims to design and develop a web-based e-library application to improve the efficiency and accuracy of library administration. The system was developed using the Extreme Programming (XP) method, which emphasizes incremental development, user involvement, and flexibility in handling changing requirements. Data were collected through observation, interviews, and documentation to identify system requirements. The developed application provides features for managing book data, member registration, borrowing and returning transactions, recording damaged and lost books, book procurement, and automatic report generation. MySQL is used as the database to ensure structured and integrated data storage. The results indicate that the e-library system is able to accelerate administrative processes, reduce data recording errors, and improve the quality of library services for both students and librarians.
