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.

Abstract

Background: The study conducted in the Pocut Meurah Intan Forest Park (TAHURA PMI) area aimed to analyze the outgoing activity of Heterotrigona itama worker beehives and their relationship with environmental and physical factors such as temperature, humidity, and light intensity. Methods: H. itama activity is observed from 06.00 to 18.00 WIB. Bees exiting the hive are counted using manual counting to determine the number of individuals that exit the hive for 10 minutes every hour. Observation of activities outside the nest consists of foraging, throwing garbage, and drones guarding the nest. Results showed that the peak of activity out of H. itama nests occurred at 09.00 - 10.00 WIB and 13.30 - 14.30 WIB. Results: Foraging activity was the highest nest exit activity. The relationship between light intensity factor and activity outside the foraging nest is moderate (R2 = 0.651), while temperature and humidity are weak (R2 = 0.052 and 0.091). The activity of exiting the nest to throw garbage has a moderate relationship with light intensity (R2 = 0.439) compared to temperature (R2 = 0.253) and humidity (R2 = 0.296). Furthermore, physical factors of light intensity (R2 = 0.6217) had a greater relationship with drone activity out of the nest than factors of temperature (R2 = 0.4385) and humidity (R2 = 0.4063). Activity outside the nest is positively correlated with temperature and light intensity and negatively correlated with humidity. Conclusions: Thus, it can be concluded that light intensity has the greatest influence on the activity out of the nest.

Abstract

The Soraya Research Station is are search area which was originally a former forest concession area. The purpose of this study was to determine chrysomelid beetles found at the Soraya Research Stationin the Leuser Ecosystem, which was carried out using an exploratory method through direct observation of the object using the insect net at 60 points following an existing trail. This research was conducted in August 2020-February 2021. The results showed that the leaf beetles (Chrysomelidae) obtained were 37 species and 370 individuals, consisting of 6 subfamilies, namely Subfamily Galerucinae (17 species), Cassidinae (9 species), Criocerinae (7 species), Eumolpinae (2 species), Cryptocephalinae (1 species), and Altycinae (1 species). The index value of beetle diversity in forest habitats at the Soraya Research Station is categorized as moderate (2.85).
