Abstract

The importance of student engagement and motivation in the physics learning process at the high school level, which has often been perceived as a difficult subject and less relevant to real life. Through the integration of anthropogenic phenomena, learning is expected to become more contextual and foster awareness of environmental issues. This study aims to determine students' perceptions of physics learning activities using the Problem-Based Learning (PBL) model integrated with anthropogenic phenomena. The research was conducted at the high school level using a quantitative descriptive approach. The respondents consisted of 108 tenth-grade students who had participated in physics learning using this model. The research instrument was a validated questionnaire. Data were analyzed using a Likert scale and presented in percentage form. The results of the study indicate that students' perceptions of physics learning using the integrated anthropogenic PBL model are in the good and very positive categories. This is demonstrated by the percentage of engagement aspects exceeding 80% and the motivation aspects reaching 86%. Overall, both aspects scored 61% or higher, indicating that the application of this model is effective in enhancing student engagement and motivation in learning. These findings are expected to serve as a reference for teachers in developing contextual physics learning and contribute as supporting literature for future research.

Abstract

Maritime safety in Indonesia is highly influenced by oceanographic dynamics such as waves, surface currents, and winds, especially along critical routes like Tanjung Perak–Lembar. However, studies integrating these parameters with recent marine meteorological data for this route remain limited. This study aims to assess seasonal variability in wave height, current speed, and wind conditions in 2024 to evaluate potential risks to navigation. A quantitative approach was applied using secondary data from the BMKG InaWave model, focusing on seven observation points along the route. Analysis was conducted using Python and Excel for spatial mapping and temporal trend visualization. Results show that (1) wind speeds during the southeast monsoon reached 7.14 m/s, contributing to wave heights up to 0.87 meters; (2) surface currents exceeding 100 cm/s were frequently identified in the Lombok Strait; and (3) the combination of strong currents and moderate waves increases safety risks for small vessels and barges. These findings highlight the importance of incorporating updated marine meteorological data in voyage planning and early warning systems. The study contributes to regional maritime safety research and supports practical decision-making for ship operators and port authorities.
