Secure Visual Image Encryption Using Lorenz Chaos, Steganography, and Wavelet-Based Steganography Authentication
Advance Sustainable Science, Engineering and Technology
Vol 7
, No 4
(2025)
Medical images play a vital role in diagnosis and clinical decision-making, yet their transmission and storage pose significant privacy and security challenges. This research proposes a visual stego-encryption system that integrates the Lorenz chaotic algorithm with Discrete Wavelet Transform (DWT) to embed both secret medical data and a doctor's digital signature into a visually meaningful encrypted image (VMEI). The system employs dual-layer embedding and role-based access control, allowing ad...

Review of Secondary Metabolite Identification Methods and Antimicrobial Activities of Tubers in Indonesian
Journal of Food and Agricultural Product
Vol 5
, No 2
(2025)
The activity of inhibiting bacterial growth has been extensively studied from various natural materials in Indonesia. One part of plants which is contains active compounds that inhibit bacterial growth is local tubers such as gadung, sweet potatoes, porang, suweg, and several other types of tubers. The bacterial inhibitory secondary metabolite compounds contained in tubers like saponins, tannins, quinones, flavonoids, alkaloids, and phenols. These compounds exhibit antibacterial activity in the...

The incorporation of wood dust and crumb rubber waste as filler in polymer matrix composite still requires in-depth evaluation of mechanical properties because they have different characteristics. This study evaluates the tensile, flexural, and hardness properties of epoxy composites reinforced with various fractions of wood dust and crumb rubber (5, 10, and 15%). The results showed that the composite with 5% crumb rubber produced the highest tensile strength of 15.52 MPa (CR5), while the highes...
