Abstract

This study aims to analyze the effect of e-commerce adoption on the sales performance of Micro, Small, and Medium Enterprises (MSMEs) in Indonesia. E- commerce adoption factors are measured through the dimensions of platform usage, technology integration, and digital marketing activities. Sales performance is assessed based on sales growth, market expansion, and increase in customer numbers. The research method uses a quantitative approach by distributing online questionnaires to 250 MSME owners in five major cities (Jakarta, Surabaya, Bandung, Medan, Makassar) who have used at least one e-commerce platform (such as Tokopedia, Shopee, Bukalapak, or a standalone website) for at least one year. Data were analyzed using multiple regression analysis techniques with the help of SPSS 25 software. The results show that e-commerce adoption has a significant positive effect on the sales performance of MSMEs. Specifically, technology integration (such as the use of inventory management and digital payment tools) and digital marketing activities (advertising and promotions on social media) are the most dominant factors. These findings provide practical implications for MSME owners and policymakers to further encourage digitalization by providing training and supporting infrastructure.

Abstract

The problem in managing payment of the Educational Development Contribution (SPP) at SMA Negeri 19 Medan lies in the system that relies on manual recording and payment cards. This creates obstacles such as delays in generating financial reports and difficulties monitoring students' late payments. To address this issue, implementing a computerized SPP payment information system is essential. The objective of this research is to accelerate financial reporting in real-time, facilitate monitoring of student payments, and provide parents with access to monitor payment statuses and receive late payment notifications. The research method employs the System Development Life Cycle (SDLC) as the primary framework for designing and developing the SPP payment information system. The stages include planning, analysis, design, implementation, testing, and integration, as well as maintenance. Data sources were obtained through interviews with various school stakeholders, including the school treasurer, principal, and several students. The purpose of the interviews was to identify existing problems and understand the mechanisms of SPP management. Data management was conducted using MySQL, specifically through CRUD operations (Create, Read, Update, and Delete) and MySQL queries. This approach simplifies the addition and monitoring of data. The research findings indicate that implementing this web-based information system provides an effective solution to the problems in managing the school payment system at SMA Negeri 19 Medan.

Abstract

Inventory management at UD Chandra is currently still carried out conventionally, through manual record-keeping and the use of simple, non-integrated spreadsheets. This causes various operational problems, such as a high risk of human error, inaccurate stock data, slow report generation processes, and difficulty for the owner in monitoring product availability in real time. On the other hand, customers also face obstacles in obtaining product availability information because they have to contact the store directly. This research aims to design and build a website-based inventory data recording information system to optimize inventory management and improve information transparency for customers. The system development method used is Rapid Application Development (RAD), chosen because it emphasizes development speed, flexibility, and intensive user involvement through the stages of requirement planning, design workshop, and implementation. The result of this research is a website-based platform that provides features for item data management, recording of incoming and outgoing transactions, automatic stock reports, low-stock notifications, and a product catalog for customers. The implementation of this system is expected to improve operational efficiency, data accuracy, and the quality of strategic decision-making for business owners, as well as provide easier access to information for UD Chandra's customers.

Abstract

Selecting the right laptop is a challenge for consumers due to the wide variety of brands, specifications, and prices available on the market, including for customers of B-Computer, a technology device store located in Binjai City. This difficulty arises because choosing a laptop requires considering multiple criteria simultaneously, such as price, processor, RAM, storage, VGA, weight, and battery life, while consumers' limited technical knowledge often makes the decision-making process complicated and time-consuming. This study aims to design and implement a web-based Decision Support System (DSS) to help consumers determine the best laptop according to their needs and budget in an objective and measurable way. The method used in this study is Research and Development (R&D), applying the Simple Additive Weighting (SAW) method, a weighted sum method that normalizes the decision matrix based on benefit and cost criteria to produce a ranking of laptop alternatives. The system was built using the JavaScript programming language and a MySQL database. Black Box Testing results show that all system features, including admin login, laptop data management, criteria preference input, and the calculation and display of recommendation results, function properly, achieving a 100% success rate across all tested scenarios. The application of the SAW method in this system is proven capable of producing objective, accurate, and scientifically accountable laptop recommendations, thereby simplifying and speeding up the consumer decision-making process without the need to manually compare laptop specifications.

Abstract

The rapid development of e-commerce has significantly increased the volume of sales transactions and customer interaction data. This presents an opportunity for businesses to leverage data mining techniques to extract valuable insights that support decision-making processes. One such application is the development of product recommendation systems, which play a crucial role in enhancing customer satisfaction and driving sales. This research focuses on utilizing sales transaction data to build a product recommendation system using the Apriori algorithm, a well-known method for association rule mining. The study begins with the collection and preprocessing of transaction data from an e-commerce platform. Through the application of the Apriori algorithm, frequent itemsets are identified, and association rules are generated based on specified support and confidence thresholds. These rules reveal purchasing patterns and relationships between products that are frequently bought together. The system then uses these patterns to recommend relevant products to users, aiming to improve cross-selling opportunities and personalize the shopping experience. The results demonstrate that the Apriori-based recommendation model is effective in identifying meaningful product combinations and can be implemented as a lightweight, interpretable alternative to more complex machine learning methods. Furthermore, the system helps e-commerce businesses optimize inventory management and marketing strategies by understanding customer buying behavior. This research concludes that the integration of the Apriori algorithm into recommendation systems provides tangible benefits for e-commerce platforms seeking data-driven personalization solutions.
