Abstract

Traditional retail, as well as micro, small, and medium-sized firms, play an important part in the Indonesian economy. However, with the rise of progressive business competition, such as competition from modern retail, traditional retail requires a strategy to better its business and performance. The purpose of this study is to identify consumer behavior in traditional retail based on data mining using Association rules-market basket analysis (AR-MBA). Data were gathered by collecting 150 shopping transactions. Furthermore, the pre-processing stage involved data cleansing, transformation, and reduction. The study's findings revealed that several association rules were established and validated. Based on these findings, various insights were obtained, including the fact that department 3 (snacks) is the most purchased item and is associated with items in other departments; there are association rules between powdered drinks and snacks, candy and snacks, toiletries, snacks, instant noodles and snacks, cigarettes and flavored drinks, and mineral water and flavored drinks. The findings are used to improve the performance and to expand the retail industry. This study recommends product stock management by increasing the number of products that consumers frequently purchase, product marketing strategies such as discounts, product bundling, and other promotions, and layout proposals based on association rules.

Abstract

Decision support system is a system that can be a problem solving quickly, especially in ranking and identifying the score of choices from highest to lowest. The research conducted aims to use the MOORA approach in determining superior products, so that it can help companies in the marketing process, selection, and production decisions based on the best product recommendations produced. In this research, the case study discussed is the selection of production-worthy products to meet quality. If the process is still done manually, it takes a long time and the evaluation process becomes inefficient. Therefore, a decision support system was designed to support the evaluation process. The MOORA method is used in the implementation of this system to test its accuracy. The results obtained from this system will be tested through sensitivity tests to criteria, value weighting, and correction tests, with the aim of knowing the number of criteria that can be added.

Abstract

Most people have switched to using bottled drinking water that is consumed compared to PDAM water that is cooked by themselves. Therefore, the determination of the shortest route for the distribution of bottled drinking water delivery (AMDK) to the last distribution route is carried out. Determination of the shortest route taken in carrying out distribution is carried out because there are often vacancies at agents caused by delays in delivery by the depot so that in this case the distribution of bottled drinking water becomes very crucial in fulfilling public demand for bottled drinking water needs. Delays in distribution from the depot can be caused by a lack of efficiency in the delivery path so that several obstacles are encountered during the process. Therefore, the shortest route optimisation will be carried out for the efficiency of distribution time which aims to increase customer satisfaction related to product availability in accordance with the demand submitted by the community which is expected to have a smooth distribution path that will impact on the timeliness of product arrival using the Vehicle Routing Problem (VRP) method. Where this method is used in a distribution system to create an optimal route. Based on the results of determining three preferred routes, for determining the distribution route from Kasomalang to the final destination, Garut, the second route was selected as the shortest route determined by

Abstract

The advancement of information technology in the healthcare sector has driven the digitalization of services, including the management of reservations and schedules in dental practices. The Praktek Gigi Mandiri Website was developed to assist the dental clinic of drg. Susilawati in efficiently managing patient appointments through the Booking and Scheduling features. This study aims to test the functionality of these features using the Black Box Testing method with the Equivalence Partitioning technique, focusing on functional Testing without considering the internal structure of the system. Testing was conducted on several main scenarios, including viewing schedules, adding schedules, editing schedules, deleting schedules, and making reservations. The test results indicate that the Booking feature achieved a success rate of 50%, while the Scheduling feature reached 57.14%. Overall, the combined success rate of both features is 53.85%, showing that most functions operated as expected. However, some scenarios failed due to insufficient input validation and inadequate error handling. The limitation of this Testing lies in its focus on functionality without involving performance and security Testing. Therefore, further Testing is needed to ensure system stability and security before full implementation. Overall, the Praktek Gigi Mandiri Website has successfully performed its main functions, but further improvements are necessary to enhance system reliability and user experience.

Abstract

The increasing consumer demand for mukena products has an impact on the production process which is required to be fast until the product reaches the consumer. However, the long distance between the production process which is still separated by the location between the warehouse and the production floor causes the ineffectiveness of the production process. To overcome this, Konveksi Roemah Dia must increase production by designing a new production site that has a layout with a minimum distance between production rooms. The purpose of this study is to design a production layout using the Systematic Layout Planning (SLP) method to design the relationship between activities. The results of data processing obtained a floor area between raw materials, cutting tables, sewing machines, embroidery machines, quality control, to finished product warehouses of 43.36 m2. Furthermore, a table of the level of activity proximity relationships was created using the Activity Relationship Chart (ARC) which was summarized into the Worksheet for Activity Relationship Diagram (WARD), then a new layout experiment was made using the Activity Relationship Diagram (ARD), finally a proposed layout was made using the Area Allocation Diagram (AAD) with a U-shaped pattern and a distance of movement between facilities of 13.5 m. The new production floor is carried out in the same place so that there is no waste of distance and time for the material movement process.

Abstract

This paper presents an analysis of the Internet Movie Database (IMDb) using the Support Vector Machine (SVM) algorithm for sentiment classification. IMDb, as one of the largest online movie review platforms, offers a vast dataset of user reviews, which can be leveraged to analyze public opinion on movies. The goal of this study is to classify movie reviews as positive or negative using SVM, a machine learning algorithm known for its effectiveness in binary classification tasks. The dataset, consisting of thousands of IMDb reviews, undergoes pre-processing steps such as tokenization, removal of stop words, and text vectorization using Term Frequency-Inverse Document Frequency (TF-IDF). The SVM algorithm is then applied to this processed data to train the model, which is evaluated based on its accuracy, precision, recall, and F1-score. Experimental results indicate that the SVM model performs with high accuracy, proving its reliability in sentiment analysis tasks for large-scale movie review datasets. This paper also discusses the advantages of using SVM over other machine learning algorithms and highlights areas for future improvement, including incorporating more nuanced sentiment categories and optimizing the model's hyperparameters.
