Abstract

Penggunaan wadah makanan berbahan plastik masih dominan di kalangan siswa SMA karena sifatnya yang praktis dan ekonomis. Namun, penggunaan berulang dan paparan panas berpotensi menyebabkan pelepasan mikroplastik yang berdampak pada kesehatan. Di sisi lain, stainless steel merupakan material alternatif yang memiliki ketahanan korosi tinggi, sifat higienis, serta umur pakai yang lebih panjang. Permasalahan utama yang dihadapi mitra adalah rendahnya pemahaman siswa mengenai risiko penggunaan plastik serta keunggulan stainless steel sebagai material yang lebih aman. Kegiatan pengabdian ini bertujuan meningkatkan literasi sains siswa melalui sosialisasi teknologi tepat guna. Metode yang digunakan meliputi pemaparan materi interaktif, diskusi, serta evaluasi melalui pre-test dan post-test. Hasil kegiatan menunjukkan adanya peningkatan pemahaman siswa terkait bahaya mikroplastik dan pentingnya pemilihan material yang tepat. Kegiatan ini berkontribusi dalam membentuk kesadaran siswa terhadap penggunaan material yang aman, higienis, dan berkelanjutan dalam kehidupan sehari-hari.

Abstract

The coastal waters of Parepare City exhibited pronounced water quality dynamics during the 2024–2025 period, as reflected by fluctuations in the spatially averaged Normalized Difference Chlorophyll Index (NDCI) values ranging from −0.07 to 0.21. This study aims to analyze the spatial and temporal variability of chlorophyll-a in the coastal waters of Parepare using Sentinel-2 imagery and to evaluate the relationship between NDCI and bio-optical parameter estimates derived from the Case-2 Regional CoastColour (C2RCC) algorithm. The analysis was conducted using Google Earth Engine for NDCI computation and extreme-condition selection, accompanied by data quality filtering based on water-body masking and cloud screening. Two extreme conditions were identified, namely the HIGHEST condition on 14 January 2024 (mean NDCI = 0.2126) and the LOWEST condition on 28 May 2025 (mean NDCI = −0.0719), which were subsequently analyzed using the C2RCC algorithm applied to Sentinel-2 Level-1C imagery through the SNAP software. The results indicate that the coastal waters of Parepare exhibit typical Case-2 water characteristics, in which spatial variability in chlorophyll-a is generally associated with changes in Total Suspended Matter (TSM) driven by terrestrial material inputs. Although NDCI is effective as a relative indicator of chlorophyll-a variability, the occurrence of anomalies in littoral zones caused by mixed pixels highlights the necessity of integrating spectral indices with C2RCC based bio-optical estimates for robust monitoring of optically complex coastal waters.
