Abstract

This study aims to estimate the length of the Sumbawa Island coastline using a fractal geometry approach with the Box-Counting method. This method was chosen because it is able to describe the complexity and self-similarity of natural forms such as coastlines. Coastline image data was obtained from USGS Earth Explorer and processed using ArcGIS software and Python to perform edge detection. Calculations were performed at several map scales, namely 1:800,000, 1:900,000, and 1:950,000. The results show that the fractal dimension value of the Sumbawa Island coastline is relatively stable between 1.20882 and 1.21245, with an estimated coastline length ranging from 1702.79 km to 1760.86 km. The smallest error value of 0.1% was obtained at a scale of 1:800,000, which is considered to produce the most accurate estimate. These results indicate that the fractal approach is effective for estimating the length of complex coastlines, and provides a deeper understanding of the coastline paradox phenomenon in coastal geomorphology.

Abstract

This community service activity aims to enhance students’ digital literacy through the introduction of basic coding at SMP Negeri 1 Praya Tengah. Digital literacy is an essential competence in the era of information technology, encompassing not only the ability to operate digital devices but also the capacity to think logically, critically, and creatively in solving problems using technology. This program was implemented by the MBKM MAPS team from the Department of Mathematics, University of Mataram, involving seventh-grade students as participants. The implementation stages included preparation (coordination and planning), execution (introduction to basic coding concepts using the Python language on the Google Colab platform), and evaluation through pre-test and post-test to measure the program’s effectiveness. The results of the paired samples t-test analysis indicated a significant improvement in students’ abilities after participating in the training, with a mean difference value of  and a significance value of . These results demonstrate that the activity successfully improved students’ understanding of programming logic and computational thinking skills. In addition to the statistical improvement, observations showed high enthusiasm among participants in practicing simple coding tasks. Overall, this activity has had a positive impact on enhancing digital literacy and represents an initial step in fostering a technology-based learning culture within the school environment.
