Abstract

vanilla. The Milk Café was founded in 2015 which currently has 3 branches and 5 franchises in various cities in Central Java and D.I. Yogyakarta and many more. the milk café owner has plans to open a new café branch. The milk café owner does not yet have the right method for determining location selection recommendations. Currently, café owners only conduct surveys and then choose locations that they think are appropriate based on several criteria so that café owners are often hesitant in determining the right location. Choosing an improper business location can cause bankruptcy or failure to run a business. This study aims to find out how the AHP method is able to provide problem solving solutions in the selection of locations in the expansion of the café business. And how to build a decision support system application AHP method. The data used are location data to conduct a feasibility survey based on criteria data to locations that have been determined by the team leader, where the criteria for determining new cafes are strategic locations, market share, competitors, rental prices and area size ... results from AHP calculations for expansion of the café is that it can be concluded that the alternative location of Jl. Sultan Syahrir Surakarta was stated as the most suitable location to be chosen as the location of the new branch of The Milk Café with the highest weighting value of 0.235. While the least recommended alternative locations are Jl. Adi Soemarmo with the least total weight is 0.153.

Abstract

The increasing use of credit cards in global financial transactions offers significant convenience for consumers and businesses. However, credit card fraud remains a major challenge due to its potential to cause substantial financial losses. Detecting credit card fraud is a top priority, but the primary challenge lies in class imbalance, where fraudulent transactions are significantly fewer than non-fraudulent ones. This imbalance often leads to machine learning algorithms overlooking fraudulent transactions, resulting in suboptimal performance. This study aims to enhance the performance of Multilayer Perceptron (MLP) in addressing class imbalance by employing cost-sensitive learning strategies. The research utilizes a credit card transaction dataset obtained from Kaggle, with additional validation using an e-commerce transaction dataset to strengthen the robustness of the findings. The dataset undergoes preprocessing with RUS and SMOTE techniques to balance the data before comparing the performance of baseline MLP models to those optimized with cost-sensitive learning. Evaluation metrics such as accuracy, recall, F1 score, and AUC indicate that the optimized MLP model significantly outperforms the baseline, achieving an AUC of 0.99 and a recall of 0.6. The model's superior performance is further validated through statistical tests, including Friedman and T-tests. These results underscore the practical implications of implementing cost-sensitive learning in MLPs, highlighting its potential to significantly enhance fraud detection accuracy and offer substantial benefits to financial institutions.
