Abstract

Bluder Cokro Store, located at Pakuwon Mall, specializes in traditional bluder bread with a wide range of flavor variations. This study aims to identify consumer purchasing patterns at the store to enhance promotional strategies and optimize product placement. The research applies the Cross Industry Standard Process for Data Mining (CRISP-DM) methodology, which includes phases such as business understanding, data understanding, data preparation, modeling, evaluation, and deployment. The dataset used consists of 4,371 transactions from October to December 2024. This study uses the Apriori algorithm to find patterns of association between products, with the goal of determining the scope of correlation between products and frequently co- purchased items. The results reveal nine significant association rules, with the strongest relationship observed between coklat keju and keju, having a support value of 0.100394 and a lift of 1.31. These findings indicate that strategic product placement and bundling promotions can enhance sales performance. Optimizing the store layout by placing coklat keju near coklat can increase purchase likelihood, while targeted discounts, such as "Buy coklat keju, get 10% off keju," can drive transaction values. This study serves as a recommendation framework rather than an experimental validation, offering insights on how transaction data and association rule mining can inform business decisions. The findings offer actionable insights for improving store layouts and promotional effectiveness, making this research valuable for retailers.

Abstract

The testing process is not only useful for testing existing features, but also for finding errors on websites and mobile applications. It also provides feedback to the developer about the application being tested. To test large scale applications, a test automation is needed so that testing can be done more efficiently and effectively. Katalon Studio is an automation testing tool developed by Katalon LLC to automate testing on websites, API's and mobile applications. The programming languages used to create scripts in Katalon Studio are Groovy, Java, and Javascript. The scripting technique provided by Katalon Studio is a keyword driven approach where keywords in the method of Katalon Studio are used to represent the actions performed by tester on the application being tested. Katalon Studio will also facilitate tester in documenting testing results or test reports in the form of charts, graphs, and detailed reports using Katalon Analytics. The results of the testing show that the use of Katalon Studio helps both beginner and experienced tester create and design automation testing on websites, APIs, and mobile applications with spy and record utilities features. Katalon Studio also provides interactive test reports in the form of graphic visualization. From the results of API testing, it can be concluded that Katalon Studio makes it easy for tester to do end to end API testing without additional integration with other software.

Abstract

In the current digital era, e-commerce has emerged as a primary choice for many business actors, particularly Micro, Small, and Medium Enterprises (MSMEs) specializing in batik products. Live streaming commerce has gained popularity as an effective marketing strategy, enabling direct interaction between sellers and consumers. However, challenges such as audience engagement and the need for prompt responses to questions or comments during live sessions pose significant issues that need to be addressed. To assist MSMEs optimize this strategy, the application of Artificial Intelligence (AI) and Machine Learning (ML) technologies can provide innovative solutions. LYFY, an AI-driven e-marketplace platform, was developed to support batik MSMEs by facilitating product promotion, enhancing consumer interaction, and enabling efficient transactions through features such as live streaming and size prediction tools. To assess the effectiveness of LYFY's user interface and overall experience, a usability evaluation was conducted using two standardized frameworks: ISO 9241-11 and the Usability Metric for User Experience (UMUX-Lite). The finding suggests that LYFY provides a high-quality user experience and is well-positioned to support the digital transformation of Indonesia’s batik SMEs.

Abstract

Pada era digital saat ini, banyak kemudahan yang ditawarkan oleh internet. Mulai dari kemudahan pertukaran informasi, efisiensi waktu, ketelitian perhitungan dll. Begitu juga dengan sistem pencatatan jual beli yang relatif mudah dan cepat dapat membantu para pelaku usaha untuk menggerakkan bisnisnya. Namun, tidak semua usaha / bisnis menggunakan komputer dalam operasional bisnis mereka. Toko Kutus-Kutus Bajra masih menggunakan metode konvensional seperti pencatatan transaksi serta stok secara manual. Hal ini mengakibatkan pemilik Toko Kutus Kutus Bajra menjadi kewalahan mencatat satu demi satu pesanan pelanggan juga menimbulkan masalah baru yaitu pelayanan yang lambat. Oleh karena itu dibangun aplikasi sistem pencatatan transaksi dan stok yang terdigitalisasi dengan database pada perangkat laptop.
