Penguatan literasi data lingkungan berbasis numerasi untuk mendukung aksi komoinutas hijau perkotaan di Kota Makassar

Abstract

Environmental actions that are not supported by reliable data risk remaining activities without measurable evidence of change. This challenge is particularly relevant for environmental communities in Makassar City, where systematic data collection and interpretation are needed to document, evaluate, and communicate the impact of community-based environmental initiatives. This Community Engagement Program aimed to strengthen environmental data literacy and numeracy skills among volunteers of the Makassar Green Community and to improve their capacity to manage and utilize environmental data (e.g., waste volume, planted mangroves, and participants) to support evidence-based environmental action. The program involved 30 volunteers and was implemented through socialization, participatory training, data recording and processing practices, mangrove planting activities, and mentoring in the development of a spreadsheet-based environmental database and simple data visualizations. Program effectiveness was evaluated using written pretest and post-test assessments of contextual numeracy literacy, analyzed using percentage improvement and N-Gain. The results showed an increase in the mean score from 60.13 on the pre-test to 80.63 on the post-test, representing an improvement of 20.50 points or 34.09% relative to the baseline score. Furthermore, 21 participants (70%) achieved the targeted minimum improvement of 30%. The program also produced a functional spreadsheet-based environmental data recording system and simple data visualizations to support community activity documentation and evaluation. These findings demonstrate that contextual, numeracy-based data literacy can strengthen volunteers’ capacity to understand, process, and utilize environmental data for more measurable and sustainable environmental education, evaluation, and advocacy.
