Abstract

In the digital era, cybersecurity and data protection are crucial issues due to the increasing frequency and complexity of cyber threats. Personal data protection is now not only a technical issue, but also a social challenge that affects social resilience in the midst of globalization. This study aims to analyze the relationship between cybersecurity policy, public perception of data protection, and its impact on social resilience in various regions. A mixed-methods approach combining quantitative surveys and qualitative interviews was used to collect data from 500 respondents in Europe, Southeast Asia, North America, and Latin America. The results show that stronger cybersecurity frameworks, such as GDPR, are associated with high public trust and social resilience towards digital services. In addition, public perception and awareness of data protection policies have a significant impact on the effectiveness of these policies, with more informed communities showing higher levels of social resilience. The study also found that data breaches have a huge social impact, undermining trust and undermining community cohesion. However, an effective response to such breaches can restore public trust and strengthen social resilience. These findings suggest the importance of raising public awareness and strengthening cross-sector collaboration to strengthen social resilience to cyber threats.

Abstract

The rapid development of technology poses challenges in electronics education, particularly in students' ability to observe and test electronic components such as transistors. This study aims to systematically observe and measure transistor characteristics by identifying codes and numbers on the transistor body, determining voltage parameters, and analyzing LED lamp load conditions. The research employs an experimental approach with direct measurements using a multimeter and power supply coupled with circuit components. The BC 547 transistor base terminal functions as a switch, with voltage inputs ranging from 2 Vpp to 4 Vpp applied incrementally (2, 2.5, 3, 3.5, and 4 Vpp). In closed switch configuration, 2 Vpp produces 0 A current with lamp off, 2.5 Vpp yields 0 A with dim illumination, while 3-4 Vpp generates 0.02-0.12 A current with bright to very bright conditions. In open switch configuration, all voltage levels produce 0 A current with lamp remaining off, confirming transistor's dual function as amplifier and switch. This research contributes to basic electronics practical learning, provides measurement-based experimental procedures, and assists technicians in transistor identification within electronic circuits.

Abstract

This study aims to evaluate the effectiveness of Satellite-Derived Bathymetry (SDB) using Sentinel-2 imagery integrated with machine learning approaches for shallow water depth mapping in Raja Ampat, Southwest Papua a region characterized by complex seafloor topography and exceptionally clear waters. The methodology combines empirical regression models (green band power regression, blue band power regression, and Stumpf logarithmic ratio method) with Random Forest machine learning to predict bathymetry from spectral reflectance data. Field bathymetric data from fishfinder measurements were used for calibration and validation through Google Earth Engine (GEE) platform. Empirical regression results demonstrate that the green band model (B3) achieved the highest accuracy (R² = 0.7097, RMSE = 1.80–14.12 m across depth classes), followed by the blue band (R² = 0.6194) and Stumpf method (R² = 0.5693). The Random Forest model exhibited superior performance in capturing non-linear depth-reflectance relationships, particularly in complex substrate conditions. The green band model performed optimally for shallow to medium depths (0–20 m), while the Stumpf method showed greater stability at depths >20 m. These findings provide a cost-effective and scalable approach for bathymetric mapping in remote archipelagic regions, supporting marine conservation and coastal resource management in Raja Ampat and similar tropical marine ecosystems.
