Abstract

This study proposes a mobile-based educational crowdfunding application to support students facing financial difficulties, in line with Sustainable Development Goal (SDG) 4. The primary challenge in digital donation platforms is vulnerability to transaction manipulation and falsification of verification documents. The “EduFund” application was developed using the Flutter framework with a client-server architecture, utilizing Firebase (Auth and Firestore) and Cloudinary on the backend. This study proposes the integration of a layered security approach (Defense in Depth) encompassing three protection layers: (1) token-based authentication with Role-Based Access Control (RBAC), (2) financial transaction integrity using a digital signature (SHA-256) generated using the user’s private key, and (3) document authenticity verification using steganography with the EOF Injection method. Functional and security testing results demonstrate that the digital signature mechanism successfully validates data integrity during fund withdrawals and detects data-tampering attempts, with an average signature generation time of 1.04 ms. Meanwhile, the steganography technique successfully embeds user metadata into proof documents within an execution time range of 6.80–30.10 ms without introducing observable visual distortion, enabling digital forensic verification of donation document authenticity.

Abstract

Secure data communication is an essential requirement in the digital age, especially in the exchange of confidential information. One of the main problems is the potential for eavesdropping by unauthorised parties who can access open messages. To overcome this, this research aims to develop a website-based system that combines the Least Significant Bit (LSB) method steganography technique and the Caesar cipher method cryptography with the Dvorak keyboard layout to increase data security. The research method used is prototype method with the stages of concept formulation, prototype design, and continuous evaluation. The system was tested by inserting the word ‘TEKKOM’ into a digital image and measuring the quality using Mean Squared Error (MSE) and Peak Signal-to-Noise Ratio (PSNR). The test results show an MSE value of 0.0001466049 and PSNR of 86.47 dB, which means that the visual quality of the image does not decrease significantly and the message is successfully inserted and extracted without errors. The Dvorak keyboard layout adds a layer of security through uncommon input patterns, making it difficult for outsiders to analyse. Thus, the system is able to provide a secure, efficient, and practical solution for web-based information hiding without the need for a database and is still user-friendly.Keywords: Dvorak, Steganography, Caesar Cipher, Least Significant Bit, Website

Abstract

Dalam menghadapi tantangan Society 5.0 yang menekankan integrasi sinergis antara manusia dan teknologi, pendidikan vokasi memainkan peran krusial dalam membekali siswa dengan kompetensi relevan. Pengabdian kepada Masyarakat ini bertujuan untuk meningkatkan kemampuan berpikir kreatif siswa SMK melalui pembelajaran berbasis robotika. Metodologi yang digunakan berupa pelatihan, dan dilaksanakan selama dua hari di SMK Negeri 1 Sumedang dengan melibatkan 40 siswa dari program studi Rekayasa Perangkat Lunak, Teknik Komputer dan Jaringan, serta Elektro. Pelatihan difokuskan pada perakitan dan pemrograman Multi-Functional Mobile Robot (MMR) yang mengintegrasikan tiga fitur: Bluetooth Control, Obstacle Avoider, dan Line Follower. Evaluasi efektivitas pelatihan dilakukan melalui pre-test, post-test, dan Torrance Test untuk mengukur peningkatan kompetensi teknis dan kreativitas. Hasil analisis menggunakan uji normalitas gain (N-gain) menunjukkan peningkatan signifikan pada pemahaman konsep robotika dan kelistrikan dengan nilai N-gain di atas 0.9. Sementara itu, hasil Torrance Test menunjukkan pengembangan kreativitas siswa dengan nilai rata-rata tertinggi pada aspek elaborasi (1.94) dan keabstrakan judul (1.92). Secara keseluruhan, pelatihan ini berhasil meningkatkan 86.6% kemampuan siswa dalam lingkup creativity-driven future, menunjukkan bahwa pembelajaran berbasis robotika melalui pendekatan proyek merupakan strategi efektif untuk mempersiapkan siswa menghadapi tantangan Society 5.0. Rekomendasi untuk pengembangan ke depan meliputi perpanjangan durasi pelatihan dan pengayaan fitur robot untuk meningkatkan kompleksitas pembelajaran.
