Abstract

Mapping of potential flood-prone areas using scoring and overlay methods in Batanghari Regency has been carried out. This study aims to determine the level of flood vulnerability and the distribution of flood-prone areas. The parameters used are rainfall parameters, soil type parameters, river distance parameters, slope parameters, land cover parameters, and elevation parameters. The methods used are scoring and overlay methods with the assistance of ArcGIS 10.8 software. The level of flood vulnerability is classified into three categories: not vulnerable, vulnerable, and highly vulnerable. The results obtained in this study show that the majority of Batanghari Regency has a flood vulnerability level in the not vulnerable class, covering an area of 397,158.03 Ha (72%), with areas in the vulnerable category covering 132,119.089 Ha (24.22%), and highly vulnerable areas covering 15,380.96 Ha (2.82%). In contrast, the area that is relatively safe from flooding is the Bajubang District, which covers an area of 102,592.1 hectares (90.17%). This indicates that some areas of Batanghari Regency are prone to flooding, making it very important to take disaster mitigation actions in the Batanghari Regency.

Abstract

Climate change is a global issue requiring a strong scientific understanding, particularly of atmospheric dynamics and the factors driving rising global temperatures. However, physics learning on this topic remains dominated by theoretical approaches, limiting students’ opportunities to analyze real-time data. This study aims to develop an Earth Nullschool-assisted learning e-module on climate change materials as an interactive, contextual digital learning medium that supports 21st-century skill enhancement. This research employed a research and development (R&D) method using the 4D development model, comprising define, design, develop, and disseminate stages. The study was limited to the development stage, as the main objective was to produce a valid and feasible model. The research subjects were grade X students of SMAN 10 Kota Jambi, selected using random sampling. The instruments included validation questionnaires from material, media, and pedagogical experts, as well as student response questionnaires. Quantitative data were analyzed using a Likert scale, while qualitative analysis was obtained from comments, critiques, and suggestions from validators and teachers. The results show that the e-module received a “very feasible” rating from the three experts and a positive response from the teacher and students. Thus, the Earth Nullschool- assisted e-module meets feasibility criteria as learning medium for climate change topic.
