Abstract

The BSI mobile application is a digital platform provided by BSI bank for carrying out financial transactions via smartphone. The BSI application does not only carry out transactions, however, it provides sharia features that are adapted to Islamic sharia principles such as sharia investment, zakat and infaq and so on. The methodological process consists of collecting data from 998 reviews which are used as a dataset, preprocessing with the aim of cleaning the data using several stages. Labeling is done by analyzing the sentiment of reviews on the dataset by dividing the data 60% to 40%, resulting in a positive value of 98% and a negative value of 2%. The implementation of the Naive Bayes algorithm in this research resulted in a confusion matrix evaluation with accuracy of 98.71%, precision of 99.22% and recall of 99.48%. This research aims to improve applications through reviews on Google Playstore by analyzing sentiment so that the service and quality of their applications match user feedback.

Abstract

Web application security has become a critical concern as cyber threats evolve in sophistication and frequency. This study analyzes vulnerabilities in modern web applications using the black-box penetration testing method based on the OWASP Top 10:2025 framework within an isolated environment. The research employs VulnApp, an intentionally vulnerable web application deployed as a controlled research target, tested using three open-source DAST tools: Nmap, Nikto, and manual exploitation techniques following stages of reconnaissance, scanning, exploitation, and reporting. Results indicate 24 verified vulnerabilities distributed across 8 of 10 OWASP Top 10:2025 categories, with the combination of tools achieving a Detection Rate (DR) of 83.3%, F1-Score of 0.889, and a Risk Score Composite (RSC) of 7.39, indicating a high-risk application profile. The highest severity findings were identified in Injection (A05, CVSS 9.8), Authentication Failures (A07, CVSS 8.8), and Broken Access Control (A01, CVSS 8.1). The isolated containerized environment proved effective as a reproducible and legally compliant research laboratory.

Abstract

This study aims to design the User Interface (UI) and User Experience (UX) of a management website for a wholesale store UD. Putra Banjar in Jakarta using Figma software and the Design Thinking method. The background of this study is the need for digitalization in stock and transaction management which has so far been done manually and is considered inefficient. This study identified four main problems: the integration of Figma and Design Thinking in the design process, the involvement of owners and customers in development, increasing transaction efficiency through the website, and providing additional features to increase customer trust in the product. The Design Thinking method used includes five stages, namely Empathize, Define, Ideate, Prototype, and Test. The initial stage is carried out through interviews with owners and customers to explore needs and problems. The results of the analysis are then formulated into a design solution that is visualized in the form of a prototype using Figma. Trials were carried out by 15 users to obtain feedback to improve the design. The expected results of this study are the creation of an effective, efficient, and responsive website UI/UX design to user needs. In addition, the product review feature is expected to help customers in decision making. This research is expected to contribute to the operational efficiency of UD. Putra Banjar and become a reference in the digitalization of similar MSMEs in Indonesia.

Abstract

Perkembangan pesat teknologi informasi mendorong berbagai usaha jasa untuk bertransformasi secara digital, termasuk usaha laundry. Berkah Laundry Ciputat merupakan salah satu usaha laundry yang masih mengandalkan proses manual dalam pengelolaan transaksi, pemesanan, dan pemantauan status layanan. Berdasarkan observasi langsung, tercatat rata-rata 15–20 kesalahan pencatatan transaksi per bulan dan 70% pelanggan mengeluhkan lambatnya respons informasi status cucian. Penelitian ini bertujuan merancang dan mengimplementasikan sistem layanan e-laundry berbasis website untuk mengatasi kendala operasional tersebut. Sistem dikembangkan menggunakan metode Agile dengan empat sprint iterasi. Pengujian fungsionalitas menggunakan black box testing menunjukkan seluruh 15 skenario uji termasuk skenario error berjalan sesuai spesifikasi. Evaluasi kepuasan pengguna dilakukan melalui kuesioner kepada 53 responden dengan instrumen 7 pertanyaan berbasis skala Likert 5 poin yang telah diuji validitas (r hitung > r tabel = 0,270) dan reliabilitas (Cronbach Alpha = 0,834). Hasil evaluasi menunjukkan indeks persentase sebesar 89,54% dalam kategori "Sangat Baik".
