Abstract

Waves and currents can remove sand from the coastal areas that caused beach erosion. Beach erosion needs to be handled by building breakwater. Rubble mound breakwater is chosen to dissipate the wave energy. Rubble mound structures are widely used throughout the world; so naturally, stability tests of rubble mound structures are the most frequently conducted coastal structure model. Two-dimensional rubble mound structure physical model is carried out in a flume. The armor layer facing the seaward uses tetrapods that are placed randomly and the core layer is set to be stable by using geotube. Three different slopes of rubble mound model facing the seaward is applied, i.e., 1:1.5, 1:2, and 1:2.5, respectively. There are also four different water levels used, i.e., 38 cm, 54 cm, 63 cm, and 70 cm. The measured parameters of this study are the wave height and wave period in front of and behind the breakwater structure. The analysis that can be done is the wave absorber and transmission waves. The stability of the structure can be observed in the form of displacement armor testing on the breakwater and at toe for a wide variety of slope and water level variations.

Abstract

This community service activity aimed to enhance elementary school students’ understanding of bridge structural concepts and simple electrical circuits through individual project-based STEM learning. The activity was conducted with Grade 3–4 students in the Cibogo area, utilizing simple materials such as popsicle sticks, LEDs, wires, batteries, and switches as learning media. The methodology integrated community-based research, participatory learning, and action research approaches, in which the activities were designed based on the needs of the target community, actively engaged students in the learning process, and incorporated reflective practices for continuous improvement. Evaluation was carried out using a questionnaire to assess students’ understanding of bridge structures, simple electrical circuits, and their responses to the activity. The evaluation results indicated that most students were able to comprehend the fundamental concepts introduced and showed positive responses to the project-based learning activities (85% for bridge construction and 78% for electrical circuits). In addition to improved conceptual understanding, students demonstrated high levels of interest and enthusiasm throughout the activity. It can be concluded that this activity was effective in providing meaningful and contextual learning experiences. Future implementations may be further developed by strengthening introductory materials and diversifying project models to enhance the quality and sustainability of STEM learning in elementary school environments.

Abstract

The coastal area of Bedono Village, Demak Regency, Central Java, Indonesia, has experienced substantial land use changes due to the combined impacts of coastal abrasion, tidal flooding, land subsidence, and sea-level rise. Continuous monitoring of these environmental changes is essential to support sustainable coastal management and disaster mitigation. This study aims to analyze multitemporal land use changes between 2015 and 2025 by integrating the Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), and the Random Forest machine learning algorithm. Landsat 8 and Landsat 9 Level-2 Surface Reflectance imagery were processed using QGIS and the Semi-Automatic Classification Plugin (SCP). NDVI and NDWI were extracted as additional predictor variables to improve spectral separability before image classification. The results indicate a significant reduction in land area accompanied by extensive degradation of mangrove vegetation, particularly during the 2020–2025 period. The Random Forest classification demonstrates that integrating spectral indices substantially improves the identification of complex coastal land cover classes affected by mixed pixels. The resulting multitemporal land use maps provide reliable spatial information for evaluating coastal environmental changes and may support evidence-based decision-making for coastal disaster mitigation, climate change adaptation, and sustainable spatial planning in Demak Regency.
