Bathymetry Mapping and Simulation of Water Level in Cirata Reservoir Using Dual Beam Sonar
No full textThe Cirata Reservoir, an important water reservoir in West Java, plays a key role in hydropower generation, irrigation, and flood control. However, increasing sedimentation poses a significant threat to the reservoir’s functionality. This study maps the bottom topography and evaluates flood risks from sedimentation through bathymetric mapping and water level rise simulations. Data was collected from 22 sampling points using Deeper Sonar Pro+, providing precise depth measurements. Depths ranged from 2.1 m to 45.9 m, with an average of 22.4 m and a standard deviation of 13.46 m. The deepest areas are located in the center and near the Citarum River, while shallower areas are found at the estuaries of the Cibalagung and Cisokan Rivers due to sediment deposition. Simulations of water level rise using bathymetric and NASADEM data showed that a rise of up to 15 m would inundate the western, southern, and southwestern regions of the reservoir. Although the total volume of the reservoir is not determined, these findings underscore the need for effective sediment management to sustain the reservoir’s capacity and ecological functions. Further studies are required to estimate the reservoir’s volume and model long-term sedimentation risks to support the Cirata Reservoir's sustainability

Vocabulary Learning and Retention Using Semantic Mapping Technique At 7th Grade Of SMPN 2 Sakra Timur.
No full textAbstract: Vocabulary plays a crucial role in English language acquisition, serving as the foundation for developing listening, speaking, reading, and writing skills. This study investigates the effectiveness of the semantic mapping technique in improving vocabulary learning and retention among seventh-grade students at SMPN 2 Sakra Timur. This study employs a pre-experimental design, The study involves a single experimental group of 30 students who underwent pre-test, post-test, and delayed post-test assessments. Data were analyzed using Repeated Measures ANCOVA to find out significant differences across testing phases. The results indicate that the semantic mapping technique significantly improved students' vocabulary learning, as evidenced by a substantial increase in post-test scores compared to pre-test scores (p = 0.007, n = 0.235). However, the technique did not significantly improve students' retention, as evidenced by the non-significant interaction between time and pre-test scores (p = 0,137, n = 0.077). These findings suggest that while semantic mapping is effective in facilitating initial vocabulary learning, its impact on long-term retention remains limited
