Abstract

Logam berat merupakan satu dari banyaknya zat yang dapat mengkontaminasi suatu perairan yang tidak dapat dilarutkan bahkan dihilangkan oleh mikroorganisme sehingga dapat menyebabkan penumpukan dan pengendapan hingga ke dasar perairan. Akumulasi logam berat di perairan berdampak pada penurunan kualitas lingkungan yang dapat mengganggu ekosistem dan biota didalamnya seperti terumbu karang ikan karang, makrozobenthos, lamun dan lain-lain. Dampak tersebut menjadi salah satu potensi risiko kesehatan manusia akibat konsumsi ikan dan hidangan laut lainnya yang terakumulasi logam berat. Dalam dua dekade terakhir, penelitian logam berat telah banyak dilakukan oleh peneliti secara global, termasuk penelitian logam berat di Pelabuhan. Penelitian ini mengkaji tingkat kesusaian perairan akibat logam berat berdasarkan standar baku mutu perairan di pelabuhan Indonesia berdasarkan literatur yang tersedia.

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

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).
