Abstract

This study compares the performance of Support Vector Machine (SVM) and Random Forest (RF) algorithms in Indonesian batik image classification. Data collected from four batik categories: Pattern Batik Insang, Pattern Batik, Patterns Batik Dump, and Pattern Megamendung. Image feature extracted using Histogram of Oriented Gradients (HOG). SVM models with linear and RF kernels with 100 decision trees are trained and tested on this dataset. The evaluation results showed that the SVM has an accuracy of 88%, with precision and recall balanced between classes, while RF has an accuracy of 86%, with some classes showing excellent performance. SVM is superior in overall accuracy, but RF offers better interpretability and ease of setting parameters. The conclusions of this study suggest that both algorithms are able to effectively classify bacterial images, but the selection of the algority depends on the specific needs of the application. Further adjustment of parameters and additional preprocessing techniques are recommended to improve model performance. This research provides a strong foundation for further development in the classification of batic images using machine learning.

Abstract

Pada dunia perbankan prediksi risiko kredit merupakan aspek penting yang menentukan keberhasilan dalam pengelolaan kredit. Penelitian ini bertujuan untuk meningkatkan akurasi prediksi risiko kredit Kredit Multiguna (KMG) di Bank DKI dengan menggunakan metode Particle Swarm Optimization (PSO). Dalam konteks ini, PSO digunakan untuk mengoptimalkan dalam menemukan kombinasi parameter terbaik yang dapat meningkatkan performa model prediksi risiko kredit. Penelitian menunjukkan bahwa penggunaan Particle Swarm optimization (PSO) ini meningkatkan akurasi prediksi risiko kredit secara signifikan. Dengan menggunakan Particle Swarm optimization (PSO) menghasilkan akurasi prediksi mencapai 99,13%. Sebaliknya , tanpa optimasi PSO, akurasi yang diperoleh dari Decision Tree hanya sebesar 97,83 %. Hal ini membuktikan bahwa PSO mampu meningkatkan akurasi prediksi risiko kredit secara signifikan. Dengan demikian, Bank DKI dapat mengambil keputusan yang lebih tepat dalam pemberian kredit KMG, yang pada akhirnya dapat mengurangi tingkat kredit macet dan meningkatkan stabilitas finansial bank.

Abstract

Drl.Rumahan is a retail store that sells a variety of motorcycle lamp modifications. Drl.Rumahan is still struggling with determining stock levels and understanding customer purchases. Additionally, they are not utilizing transaction data as a valuable information source. Without leveraging this data, Drl.Rumahan will fall behind its business competitors and lose customers because the products they seek are unavailable. This situation will inevitably become a significant problem if it continues. This study aims to utilize sales transaction data as valuable information and identify customer purchasing patterns from the sales transaction data. The algorithm used is the Apriori algorithm to identify purchasing patterns from the transaction data set. The results of this study identified the three highest rules: if someone buys a pass beam switch, they will buy a shroud with a support value of 5.8% and a confidence value of 47.6%; if someone buys a shroud, they will buy a pass beam switch with a support value of 5.8% and a confidence value of 45.5%; and if someone buys a shroud, they will buy a relay with a support value of 5.2% and a confidence value of 40.9%. These results can inform business strategy decisions by increasing the inventory of products that form rules and serve as a guide for promotional product packages for products that have rules above the minimum support and minimum confidence.

Abstract

Risk management plays a crucial role in software quality assurance (SQA) to reduce the potential for failures that impact software quality. This study aims to explore the implementation of risk management in black box testing for inventory maintenance applications, focusing on identifying and managing risks that arise within the system. The study employs risk identification, impact analysis, and risk frequency evaluation methods applied to black box testing scenarios. The black box testing results revealed no errors in the system’s features during the tests. This research identifies 18 potential risks, such as feature errors and interface function failures, which can be minimized through mitigation strategies, including user training and preventive and corrective maintenance. The findings conclude that the system design has been well-executed and operates optimally. However, preventive measures are still necessary to ensure the system continues to function effectively.

Abstract

Roma Bangunan is one of the mainstay building stores of the Karawang community, offering a wide range of building material products. However, this store faces the challenge of unstable stock inventory which hampers operations and service to customers. Inconsistent stock can lead to service delays, lost sales, and reduced customer satisfaction. Therefore, the author uses Rapidminer with the application of a priori algorithm to find sales combination patterns in sales transaction data, so that this combination pattern will later become information on what goods must have more and less stock of goods, thus minimizing the occurrence of overstocking. In this study, 3 association rules/combination patterns were produced that met the minimum support of 10% and confidence of 50%, namely for the highest association rule "If consumers buy sandpaper, then buy White Brush" with a support value of 12%, confidence of 69% and an elevator ratio of 3.11. By implementing Rapid Miner and a priori algorithms, Roma Bangunan Stores was able to leverage existing data to make better decisions, optimize inventory management, and ultimately improve customer satisfaction and overall business performance.
