Abstract

Coastal zones are inherently dynamic, often resulting in long-term cumulative impacts such as erosion, which can potentially escalate into disasters. Discussions regarding nature-based solutions, particularly the utilization of coastal forests, have gained prominence due to their environ[1]mental benefits. This paper investigates the role of vegetated coasts in mitigating the effects of wave attacks on land, focusing specifically on Coastal Pandanus species. We conducted a systematic monitoring effort to quantify land changes directly around these species in the field. The southern coast of Java, characterized by significant coastal processes, served as the investigation site. We monitored the changes in the foredunes of eight Pandanus clusters identified along a 1 km stretch of the Pandansari and Samas coasts in the Special Region of Yogyakarta, Indonesia. Our systematic monitoring, conducted biweekly from September to December 2023, involved precise measurements of land elevation, sediment deposition, and erosion around the Pandanus clusters. We utilized manual leveling surveys and installed erosion pins to enhance the precision of our topographic assessments. These monitoring techniques allowed us to thoroughly examine the relationship between Pandanus cluster characteristics and coastal processes. Our findings illuminate the pivotal role of Pandanus clusters in shaping coastal profiles, which depend on cluster area and growth characteristics. Additionally, we underscore key points regarding their success rates, limitations, and future strengthening efforts through the implementation of this nature-based solution. This research contributes to a deeper understanding of the complex interactions between coastal dynamics and vegetative elements, paving the way for informed coastal management strategies in the future.

Abstract

This study aims to investigate the effect of Show and Tell on students’ Speaking Ability particularly in accuracy and comprehensibility at The Eighth Grade Students of SMP Negeri Satu Atap Lik Layana Indah in Academic Year 2024/2025. This study used a quantitative approach with a Pre-experimental design using one group pre-test post-test design. In this research, the researcher used a total sampling technique with a total of sample 32 students. To analyze the data, the researcher used statistical computation by using SPSS software. After implementing Show and Tell method over six meetings, a post-test was administered to measure improvements. The results show that the mean of the pre-test score was 43.75, while the mean score of the post-test increased to 58.59, demonstrating a significant improvement. After getting the mean score the researcher performed a normality test, which showed the data were not normally distributed. Therefore, the researcher applied the Wilcoxon Signed Rank Test. The result of the test shows a significance value (Asymp. Sig. 2-tailed) is .000, which is smaller than 0.05, indicating a significant improvement in students’ speaking ability after using the show and tell method, confirming that the hypothesis (Ha) is accepted. Thus, the use of Show and Tell Method is effective in improving students’ speaking ability in terms of accuracy and comprehensibility of eight-grade students’ at SMP Negeri Satu Atap Lik Layana Indah.
