Lightweight Dual-Layer Chaotic Image Encryption Using Arnold Cat Map and Henon Zigzag Diffusion
Umam, Chaerul

; Nursetyo, Arif
; Sugiarto, Bambang
; Islam, Husain Md Mehedul
Digital image transmission over open networks raises significant security concerns due to the high correlation and predictable statistical properties of image data. Existing chaotic encryption schemes based on Arnold Cat Map (ACM) and Henon mapping often suffer from high computational cost, parameter sensitivity, or reliance on complex multi-stage designs. To address these limitations, this study proposes a lightweight dual-layer chaotic image encryption framework that integrates ACM-based pixel...

; Salleh , Mohd Shukor
Blasting activities are among the most important in mining and can have a negative impact on the environment and surrounding communities, causing disruption and even damaging nearby buildings and infrastructure. If the community protests and demonstrates, mining operations may be shut down, which would be very detrimental to the company. Studies are needed on effective planning to reduce the negative impacts. Ground vibrations measured by Peak Particle Velocity (PPV) are subject to thresholds se...

Accurate monitoring of mouse behavior in the Elevated Plus Maze (EPM) is essential for anxiety-related biomedical research, yet manual observation is time-consuming, subjective, and prone to human error. This study proposes an optimized automated tracking framework that integrates YOLOv8 detection with tracking methods including an adaptive Kalman Filter and DeepSORT, and compares them with conventional trackers such as CSRT and GOTURN. System performance was evaluated using Intersection over Un...

The influence of self-concept conflict and parental influence on emotional and personality-related career decision-making difficulties in special sports class students
This study aims to explore how self-concept conflict and parental influence impact the emergence of emotional and personality barriers in the career decision-making process, specifically among KKO students at SMA Negeri 1 Pengasih. This study employed a quantitative correlational method, involving 108 students as a sample using a saturated sampling technique. Validity was assessed through expert judgment, while reliability was calculated using Cronbach's Alpha. Data were statistically processed...

The effect of role playing on social interaction
This research was motivated by the results of observations that found a number of students were still unable to interact optimally. Some students tend to be solitary, show awkwardness when dealing with new friends, lack courage in communicating, and have difficulty working together with peers outside their circle of friends and are reluctant to get involved in group activities. This study aims to determine the influence of role playing on social interaction. Researchers use group guidance servic...

Introduction: Age-related declines in muscle strength, proprioception, and postural control contribute to balance impairment among older adults and increase the risk of falls. Non-pharmacological interventions, particularly structured physical exercise combining relaxation and balance training, have been recommended to improve balance performance. This study aimed to evaluate the effect of a combined Hatha Yoga and Tandem Walking Exercise program on balance among older adults in Malang. scores....
