Abstract

Facial expression-based emotion recognition has various applications, including security, healthcare, human-computer interaction, and behavioral analysis. This study analyzes the effectiveness of the Kolmogorov Arnold Networks and Convolutional Neural Networks algorithms in classifying human facial expressions of emotion using the OSEMN. Experimental data were obtained from the FER-2013 dataset, which consists of 35,887 facial expression images categorized into seven primary emotions: happy, sad, angry, fearful, disgusted, surprised, and neutral. The CNN model was designed with four convolutional layers, while the KAN model used three convolutional layers and a B-spline-based approach to handle non-linear transformations. Evaluation was based on accuracy, precision, recall, F1-score, and computational efficiency. The results showed that CNN achieved higher accuracy but tended to overfit, particularly on emotion classes with imbalanced data distribution. On the other hand, KAN demonstrated more stable performance with lower computational resource consumption, making it more efficient for systems with limited power and memory. CNN was selected for its superior pattern recognition capability, while KAN was chosen due to its efficiency in resource-constrained environments. From the comparison, CNN performed better in detecting complex expressions, while KAN was more optimal in processing efficiency and classification stability. The choice of the most suitable algorithm depends on the specific needs of the system—whether prioritizing high accuracy (CNN) or computational efficiency (KAN). This study is expected to provide insights into the development of more adaptive and efficient deep learning-based emotion recognition systems for practical applications such as mobile devices, healthcare monitoring, and smart surveillance.

Abstract

Keamanan aplikasi web merupakan aspek krusial dalam melindungi data sensitif pengguna sekaligus menjaga kepercayaan terhadap layanan digital. Seiring meningkatnya pemanfaatan aplikasi berbasis web, risiko serangan siber juga semakin kompleks, terutama terkait kontrol akses dan kerahasiaan data. Penelitian ini bertujuan untuk mengidentifikasi serta menganalisis kerentanan keamanan pada aplikasi invoice berbasis web dengan alamat https://invoice.masdzikry.com. Metode penelitian menggunakan pendekatan eksperimen melalui penetration testing, dengan bantuan Burp Suite untuk melakukan manipulasi permintaan (request), analisis parameter, serta pengujian bypass otorisasi. Hasil pengujian mengungkapkan dua kerentanan utama yang bersifat kritis. Pertama, Insecure Direct Object Reference (IDOR), di mana pengguna biasa dapat mengakses faktur milik pengguna lain hanya dengan memodifikasi parameter id pada endpoint /invoices/{id}. Kedua, Broken Access Control yang disertai dengan Sensitive Data Exposure, ditemukan melalui penyisipan header X-Original-Url yang memungkinkan pengguna tanpa hak istimewa memperoleh akses tidak sah ke halaman administratif serta data sensitif administrator. Kedua temuan ini memiliki tingkat risiko tinggi menurut klasifikasi OWASP, karena berpotensi menyebabkan kebocoran data finansial, penyalahgunaan akses, hingga pengambilalihan akun. Berdasarkan temuan tersebut, penelitian ini merekomendasikan penerapan kontrol otorisasi berbasis peran (Role-Based Access Control), validasi parameter di sisi server, penonaktifan header manipulatif, serta penerapan logging, monitoring, dan audit keamanan secara berkala sesuai dengan standar OWASP Application Security Verification Standard (ASVS). Implementasi langkah-langkah mitigasi ini diharapkan dapat meningkatkan ketahanan aplikasi terhadap ancaman eksploitasi dan memperkuat kepercayaan pengguna terhadap sistem.
