Abstract

Tourism is one of the most important things for an area. Interesting and crowded tourism shows the progress of the area. One way to promote tourism is by media promotion. There are many ways that can be used for promotion, one of which is by utilizing information technology based on Augmented Reality (AR). AR is a technology that displays 3D virtual objects into a real environment and builds visualization of 3D images in tourist brochures to be more informative. AR helps users get clearer information about the attractions they want to visit in Langsa city. The use of AR on Android makes the system more accessible to users. Based on trials, the AR system was successfully implemented on the Android system. In addition, camera trials were also carried out based on distance, tilt angle, and lighting when detecting tourist attraction markers. The result is that the camera successfully detects the target image (marker) and generates a 3D animation of a tourist attraction. However, the best results in detecting markers are distances above 15cm at an angle with cloudy sunlight lighting criteria.

Abstract

Monocrystalline and polycrystalline photovoltaic modules continue to dominate solar power system applications; however, experimental evidence based on field measurements in tropical environments remains relatively limited. This study aims to analyze and compare the performance of both PV module types through outdoor testing conducted over 30 days in Indonesia, considering the combined effects of module temperature, dust deposition, and relative humidity. The method employed was comparative field testing with real-time monitoring of key electrical parameters, namely voltage, current, and power, as well as environmental variables. The results indicate that monocrystalline modules consistently outperform polycrystalline modules, with an average power output of 102.4 W (8.6% higher) and a conversion efficiency of 17.8% (11.9% higher). Statistical analysis confirms that the performance difference is significant (p 0.0001; Cohen’s d = 1.85). Module operating temperature was identified as the dominant factor contributing to power degradation, followed by dust and humidity. Collectively, these three environmental factors resulted in an estimated power loss of 13.4% for monocrystalline modules and 16.0% for polycrystalline modules. These findings suggest that monocrystalline modules are better suited for small-scale and residential PV applications in tropical regions due to their superior performance, higher efficiency, and greater thermal resilience.
