Abstract

Breast cancer is a disease with a high mortality rate in women worldwide, making early detection a crucial factor in increasing the chances of successful treatment and patient survival. Advances in computing technology, particularly machine learning, have created opportunities to use medical data to inform decision-making in the diagnostic process. This study aims to analyze and compare the performance of the Decision Tree and Random Forest algorithms in classifying breast cancer using the Wisconsin Breast Cancer Dataset. The dataset comprises 569 data points with 30 numeric attributes representing cancer cell characteristics and a class label indicating benign or malignant cancer. The research stages include data preprocessing, splitting the data into training and test sets (80:20), applying the classification algorithm, and evaluating model performance using accuracy, precision, recall, and F1-score metrics. The test results show that the Random Forest algorithm outperforms the Decision Tree. Random Forest achieved an accuracy of 98.68% on the training data and 95.61% on the test data, while Decision Tree achieved an accuracy of 96.92% on the training data and 91.23% on the test data. This difference indicates that Random Forest has better generalization capabilities and is more resistant to overfitting. The findings of this study indicate that Random Forest is more effective for data-based breast cancer classification than Decision Tree. Therefore, the Random Forest algorithm is recommended as a more reliable method to support decision support systems in early breast cancer detection.

Abstract

This study addresses the inefficiency and uncertainty in accessing real-time fish stock information at the Pelabuhan Ratu Fish Market, where traditional manual communication methods remain dominant and hinder effective transactions. The objective of this research is to develop a user-centered mobile application, SI-KIKAN, that provides real-time fish availability information while ensuring high usability for users with diverse levels of digital literacy. This study adopts a design and development approach by integrating Agile Scrum and Agile User Experience (UX) methodologies, enabling iterative system development, continuous user feedback, and adaptive design refinement. Data were collected through field observations, stakeholder interviews, and usability testing involving 30 respondents, and analyzed using qualitative techniques and the System Usability Scale (SUS). The results indicate that the SI-KIKAN application successfully improves information transparency and operational efficiency, as evidenced by a high SUS score of 86.17, categorized as “Excellent,” demonstrating strong usability, learnability, and user satisfaction. The implementation of Agile Scrum facilitated efficient management of development complexity, while Agile UX ensured that the interface design aligned with user needs and field conditions. This study implies that the integration of Agile Scrum and Agile UX is an effective approach for developing user-centered digital solutions in traditional sectors, particularly in improving information accessibility and supporting digital transformation in fisheries markets.

Abstract

Proses pengajuan laporan Praktik Kerja Lapangan (PKL) di SMKN 1 Bojonggenteng masih dilakukan secara manual, sehingga menimbulkan berbagai kendala seperti keterlambatan pengumpulan laporan, kesulitan revisi, kurang efektifnya komunikasi antara siswa dan guru pembimbing, serta risiko kehilangan dokumen. Penelitian ini bertujuan merancang desain antarmuka pengguna (UI) dan pengalaman pengguna (UX) aplikasi mobile untuk meningkatkan efisiensi proses pengajuan laporan PKL. Metode yang digunakan adalah Design Thinking yang terdiri dari lima tahapan, yaitu empathize, define, ideate, prototype, dan test. Penelitian menggunakan pendekatan kuantitatif deskriptif dengan melibatkan 30 responden yang terdiri dari siswa dan guru pembimbing. Prototype dirancang menggunakan Figma dan diuji menggunakan metode System Usability Scale (SUS) serta evaluasi Fitur dan desain (FD). Hasil pengujian menunjukkan nilai SUS sebesar 82,42 dengan kategori excellent, nilai FD sebesar 93, dan nilai akhir sebesar 87,71. Hasil tersebut menunjukkan bahwa aplikasi memiliki tingkat usability yang sangat baik, desain antarmuka menarik, serta fitur yang sesuai kebutuhan pengguna. Dengan demikian, prototype aplikasi layak dikembangkan ke tahap implementasi sistem nyata.
Penerapan Metode User Centered Design (UCD) Pada Perancangan UI/UX Aplikasi Mobile Sistem Informasi Perpustakaan "Si-Pustaka" (Studi Kasus: Sma Plus Damar Bangsa Sukabumi) Alfiah, Ananda; Firdaus, Uus; Gautama, Budhi Gunadharma

Abstract

Perkembangan teknologi informasi dalam bidang pendidikan menuntut sistem yang mampu meningkatkan efisiensi dan kualitas layanan, termasuk pada pengelolaan perpustakaan sekolah. Namun, pengelolaan perpustakaan di SMA Plus Damar Bangsa Sukabumi masih dilakukan secara manual sehingga kurang efisien dan rentan terhadap kesalahan. Selain itu, belum tersedianya aplikasi mobile dengan antarmuka yang mudah digunakan menjadi kendala dalam peningkatan layanan. Penelitian ini bertujuan untuk merancang desain User Interface (UI) dan User Experience (UX) aplikasi mobile sistem informasi perpustakaan dengan menerapkan metode User Centered Design (UCD). Metode ini berfokus pada pengguna melalui tahapan analisis kebutuhan, perancangan, dan evaluasi secara iteratif. Pengumpulan data dilakukan melalui observasi, wawancara, studi pustaka, kuesioner, dan usability testing. Hasil penelitian berupa prototype UI/UX yang memudahkan pengguna dalam mencari, meminjam, dan memantau status buku. Evaluasi menggunakan System Usability Scale (SUS) memperoleh skor 82,75 (excellent) dengan nilai akhir 88,28, serta pengujian fitur sebesar 93,8%. Hasil ini menunjukkan bahwa desain memiliki tingkat usability yang tinggi dan layak untuk dikembangkan. Dengan demikian, penerapan metode UCD mampu menghasilkan desain yang sesuai kebutuhan pengguna, mudah digunakan, serta meningkatkan kualitas layanan perpustakaan.
