Abstract

Wilayah Kota Parepare merupakan salah satu daerah rawan banjir akibat kombinasi topografi dataran rendah, curah hujan tinggi, dan sistem drainase yang belum optimal. SMK Negeri 1 Parepare menjadi salah satu sekolah yang terdampak banjir, namun belum memiliki program edukasi kebencanaan yang terstruktur. Kegiatan pengabdian ini bertujuan untuk meningkatkan pemahaman dan kesiapsiagaan siswa terhadap risiko banjir melalui edukasi mitigasi berbasis ceramah, diskusi interaktif, dan pemutaran video simulasi. Metode pelaksanaan terdiri dari empat tahapan: perencanaan, persiapan, pelaksanaan, dan evaluasi. Sebanyak 71 siswa terlibat dalam kegiatan yang diselenggarakan di aula sekolah. Penilaian pemahaman dilakukan dengan metode pretest dan post-test menggunakan soal pilihan ganda yang relevan dengan materi mitigasi banjir. Hasil pretest menunjukkan rata-rata pemahaman awal sebesar 70,49%, dengan sebagian besar siswa berada pada kategori sedang hingga rendah. Setelah kegiatan edukasi, rata-rata nilai post-test meningkat signifikan menjadi 90,14%, menunjukkan adanya peningkatan pemahaman sebesar 30,47%. Peningkatan ini mengindikasikan bahwa pendekatan edukatif yang digunakan efektif dalam meningkatkan literasi kebencanaan di kalangan siswa. Dengan demikian, kegiatan pengabdian ini dinilai berhasil dalam membekali siswa dengan pengetahuan dasar dan kesiapsiagaan menghadapi bencana banjir di lingkungan sekolah.

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.
