Abstract

Mikroplastik kini menjadi salah satu permasalahan lingkungan yang krusial di Indonesia, dengan dampak yang signifikan terhadap ekosistem perairan serta dampak serius bagi kesehatan manusia. Penelitian ini bertujuan untuk mengidentifikasi keberadaan mikroplastik pada organisme akuatik di perairan Indonesia serta mengevaluasi potensi risiko yang dapat ditimbulkan terhadap kesehatan manusia. Penelitian ini menggunakan pendekatan kajian literatur terhadap jurnal-jurnal ilmiah yang diterbitkan dalam rentang waktu 2015 hingga 2024, dengan sumber data berasal dari Google Scholar. Berdasarkan hasil kajian, mikroplastik terdeteksi di berbagai wilayah perairan, dengan identifikasi sebanyak 17 organisme dari tiga filum moluska dan 14 organisme dari filum chordata, di mana sebagian besar berasal dari spesies ikan lainnya yang paling banyak menunjukkan indikasi keberadaan mikroplastik. Keberadaan mikroplastik memiliki potensi untuk masuk ke dalam rantai makanan, yang pada akhirnya dapat menimbulkan berbagai gangguan kesehatan pada manusia, seperti masalah sistem pencernaan, gangguan fungsi hati, serta peningkatan risiko terkena kanker. Temuan ini memberikan kontribusi penting terhadap pemahaman tentang pencemaran mikroplastik di perairan Indonesia dan menyoroti urgensi penerapan langkah-langkah mitigasi guna menjaga kesehatan masyarakat dan kelestarian lingkungan akuatik.

Abstract

Urban forests play a pivotal role in climate change mitigation by storing carbon in biomass. However, the economic valuation of this ecosystem service in Banda Aceh City remains underexplored. This study aims to quantify aboveground biomass carbon stocks and assess their economic value in six selected urban forests across the city. Non-destructive sampling was conducted using 20 × 20 m plots to measure tree diameter, estimate biomass using species-specific allometric equations, and calculate carbon content (C = 0.5 × B). A carbon price of US$50/ton was applied for economic valuation. The total carbon stock was estimated at 11,579 tons, with Putroe Phang Forest contributing the highest proportion (45%). The corresponding economic value was approximately IDR 3.42 billion. A strong positive correlation (R² = 0.9859) was observed between tree diameter and biomass. This study presents a novel economic perspective on urban forest carbon in Banda Aceh by integrating ecological data with financial valuation. The findings underscore the importance of incorporating carbon trading mechanisms into urban planning to strengthen ecosystem service assessments and climate policy implementation.

Abstract

This study investigates greenhouse gas (GHG) emissions, with a focus on carbon monoxide (CO), in Banda Aceh City to identify their sources and spatial distribution. Google Earth Engine (GEE) was utilized to process and analyze Sentinel-5P satellite data from November 2023 to November 2024. The results indicate that CO emissions are mainly generated by transportation, industrial activities, and forest fires, reflecting the significant influence of human activities on air quality. Spatial analysis reveals that northern coastal sub-districts, including Kutaraja, Kuta Alam, and Syiah Kuala, experience the highest CO concentrations, while Meuraxa and Jaya Baru show moderate levels, and southern and inland sub-districts such as Banda Raya, Ulee Kareng, and Lueng Bata exhibit low concentrations. The distribution pattern highlights the role of population density, economic activity, and land cover in shaping emission intensity. By leveraging near real-time satellite monitoring, this study provides detailed emission mapping that can guide urban air quality management and climate mitigation strategies. These findings serve as a valuable reference for policymakers and researchers in formulating emission reduction measures and enhancing climate resilience in urban environments.
