Abstract

This study aims to determine the impact of rob flood and adaptation of coastal communities in Medan Belawan District Medan City. The research method used is descriptive qualitative research method. The direct location of flooding review is at Jalan Serdang which belongs to Belawan I urban village. The result shows that the rob flood that hit Medan Belawan District has varying height. Several villages affected by the flood were Belawan I, Belawan II, Belawan Bahagia, Belawan Bahari, Belawan Sicanang and Bagan Deli. Rob flood occurs twice a day at around 02.00 am and 13.00 pm to 16.00 pm. Rob floods give impacts of damage to buildings especially shelter, increased salinity of water resources, damage to pond land, damage to work equipment or vehicles used by everyday people. Rob floods also disrupt the activities of fishers and traders because when the floods occur, fishers are forced to stop while fishing and income is reduced, as well as the supply of fish to the market. Community adaptation to rob floods in Medan Belawan District is adaptation to residential buildings and adaptation to the availability of clean water sources.Key words: coastal communities, rob flood, adaptationPenelitian ini bertujuan untuk mengetahui  dampak banjir rob dan adaptasi masyarakat kawasan pesisir di Kecamatan Medan Belawan Kota Medan.

Abstract

Critical thinking is an essential skill in the modern information era, enabling individuals to analyze complex information, evaluate arguments, and make informed decisions. In educational contexts, particularly in geography, fostering critical thinking equips students to address real-world environmental and social challenges. Problem-Based Learning (PBL) has emerged as a transformative teaching approach to develop these cognitive abilities through active, problem-centered learning. This meta-analysis aimed to evaluate the effectiveness of PBL in enhancing students' critical thinking across various educational levels. Using OpenMEE software and a continuous random-effects model, the study synthesized findings from 20 peer-reviewed studies published between 2020 and 2024. Statistical analyses focused on the standardized mean difference (SMD) as the primary metric to measure effect sizes. The results demonstrated that PBL significantly enhances critical thinking skills, with an overall SMD of 1.254 (95% CI: 0.875 to 1.633, p < 0.001). However, notable heterogeneity was observed, attributed to variations in educational levels, implementation fidelity, and study contexts. Subgroup analyses revealed that junior high school students experienced the greatest improvement, followed by university, senior high school, and elementary school students. These findings affirm PBL’s potential as an effective pedagogical strategy for fostering critical thinking. The study highlights the need for tailored PBL implementations and further research into its long-term effects and applicability across diverse educational contexts. The results provide robust evidence supporting PBL as a vital tool in modern education.

Abstract

Taiwan is a subtropic-tropic island with densely populated in the coastal plains surrounding its mountains. In recent years, due to global warming and the urban heat island effect, the surface temperature has continued to rise, and the seasonal temperature changes are also very different. Increased surface temperatures, particularly in cities, are a major environmental issue that intensifies urban heat islands (UHIs). Decadal time-series analysis has historically relied on meteorological data. Due to the limited availability of remote sensing technology, decadal analysis of land surface temperature has been a serious concern. However, according to advanced technologies in remote sensing methods and sophisticated GIS software, Land Surface Temperature (LST) now can be estimated using thermal bands. The objective of this study is to monitor the spatiotemporal changes of the land surface temperature using Landsat 5 and Landsat 8. Tainan city, which is a highly developed city in southern Taiwan, is selected as the research area. The changes in the land surface temperature are assessed between the years 2007 and 2021. It simply requires applying a set of equations through a raster image calculator using ArcGIS. The LST of any Landsat satellite image can be retrieved by following steps: 1) Top of Atmospheric Spectral Radiance; 2) Conversion of Radiance to At-Sensor Temperature; 3) Calculating NDVI; 4) Calculating the Proportion of Vegetation; 5) Determination of ground emissivity, and 6) Calculating Land Surface Temperature. Near Infra-red are used to obtain Normalized Different Vegetation Index (NDVI). The results show that the average surface temperature of Tainan City increased slightly by 1.1 0C. The most significant increase in temperature was in the northern region of Tainan City which was the agricultural area that was in the post-harvest period.Keywords: Land Surface Temperature (LST), Landsat 5, Landsat 8, Tainan City, GIS
