Abstract

Ajatappareng is a region in South Sulawesi Province, Indonesia which consists of four regencies and one administrative city. The regencies are Barru, Sidenreng Rappang, Pinrang, and Enrekang while the city is Parepare. The area has experienced a significant growth in terms of population which further leads to an increase in waste generation. Waste are a major challenge for environmental management especially due to the role in producing carbon emissions.  Aim: This study aims to assess the carbon emissions produced in waste management sector of the Ajatappareng Region. Methodology and results: The GHG Simulation-Version II spreadsheet was used to assess the GHG emissions from the transportation of waste in the respective regencies. Mathematical formulas were provided in the cells to calculate the GHG emissions of the simulation developed. Conclusion, significance, and impact study: The results showed that the volume of carbon emissions was 16,299.84 kg CO2-eq/month for Barru Regency, 17,076.03 kg CO2-eq/month for Sidrap Regency, 16,817.30 kg CO2-eq/month for Parepare City, 17,722.85 kg CO2-eq/month for Pinrang Regency, and 19,145.85 kg CO2-eq/month for Enrekang Regency. Moreover, the GHG emissions from mixed waste in the final disposal site were 918,531.01 kg CO2-eq/month, 1,733,537.85 kg CO2-eq/month, 1,404,917.59 kg CO2-eq/month, 1,723,004.12 kg CO2-eq/month, and 523,506.36 kg CO2-eq/month, respectively. Therefore, potential efforts are required to reduce CO2 emissions by optimizing waste transportation, promoting recycling, managing organic waste through composting, as well as improving collaborations with the private sector.

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.

Abstract

Flooding is one of the most frequent hydrometeorological disasters in Indonesia and has substantial impacts on communities, including the education sector. Strengthening disaster literacy among school-aged students is an essential strategy for disaster risk reduction. This community engagement program aimed to improve the knowledge, awareness, and preparedness of students at SMA Negeri 5 Parepare regarding flood disaster mitigation through an educational outreach program. The program employed lectures, interactive discussions, educational videos, and learning evaluations using pre-test and post-test assessments. The activity was conducted on January 21, 2025, involving 35 students. Program effectiveness was evaluated using post-test scores and the normalized gain (N-Gain) index. The results showed that the average post-test score reached 89.06, with the highest score of 100 and the lowest score of 70. The average N-Gain score was 0.75 (75.67%), indicating a high level of learning improvement. Furthermore, 25% of participants achieved high improvement, 72% moderate improvement, and only 3% showed no improvement. These findings demonstrate that the outreach program effectively enhanced students’ understanding of flood causes, impacts, mitigation measures, and disaster preparedness.
