Abstract

Suhu dan salinitas memiliki peranan penting dalam mencerminkan kondisi massa air dan secara langsung berpengaruh terhadap kondisi biologi dan kimia perairan. Tujuan penelitian ini adalah menganalisis dinamika angin di perairan Laut Halmahera dan mendiskripsikan kondisi suhu dan salinitas permukaan laut (SPL) di Laut Halmahera. Data yang digunakan yaitu data penginderaan jauh Marine Copernicus untuk data Suhu dan salinitas sedangkan data angin dari ECMWF. Pengolahan data menggunakan software ODV untuk mengolah data SPL dan salinitas dari tahun 2016-2020, selanjutnya data angin diolah menggunakan software surfer 16. Laut Halmahera memiliki suhu permukaan laut berkisar antara 26.20 - 31.6°C dimana kondisi maksimum terjadi bulan Mei dan November. Sedangkan salinitas berkisar antara 29.38 - 34.9 psu, dimana kondisi maksimum pada bulan Desember sampai Maret. Dinamika angin di Laut Halmahera mempengaruhi pola sebaran suhu permukaan laut dan salinitas yang ada pada perairan tersebut, dimana kecepatan angin berkisar antara 6.5 - 2.5 m/s.

Abstract

One possible way for school students obtaining environmental awareness is from environmental knowledge taught in classes. The Community Service Program of Department of Marine Science of Fisheries and Marine Science Faculty, Pattimura University in the form disseminations on literacy of coastal environment aimed to encourage school students to be pioneers and drivers for coastal conservation and beach clean-ups in their local community in Ambon Bay. The materials used in the disseminations focused on understanding coastal environment in Ambon Bay, and sources and types of pollutants in the system. The materials also covered the impacts of the coastal pollution and how to address it including to reduce and solve the pollution in Ambon Bay. At the end of the disseminations, the questions-and-answer session was conducted to evaluate the understanding of students on the knowledge of marine pollution management in Ambon Bay,

Abstract

The mangrove ecosystem is one of the potential coastal ecosystems in Ambon Bay waters, most of which are in Inner Ambon Bay.Threats to the mangrove ecosystem in the waters of Ambon Bay are the activities that take place around it. Moreover, several rivers that empty into Ambon Bay cause the entry of debris/waste from land. Previous studies have shown that Pb and Cd have been detected in seawater in Ambon Bay waters, so it is considered important to conduct research on mangrove ecosystem sediments. The purpose of this study was to determine the concentration of heavy metals (Pb and Cd) in sediments in the mangrove ecosystem of Ambon Bay. The sampling points of the sediment in mangrove ecosystems were carried out using purposive sampling method. Sample analysis was carried out at the Environmental Productivity Laboratory of IPB using the Nitric Acid-Perchloric Acid Digestion method. The results showed that the concentration of heavy metal Plumbum (Pb) ranged from 18.25-35.98 mg/kg and Cadmium (Cd) 1.57-2.70 mg/kg. The results showed that the concentration of heavy metal Plumbum (Pb) ranged from 18.25-35.98 mg/kg and Cadmium (Cd) 1.57-2.70 mg/kg. Based on the results of the analysis, it can be said that, although Pb was found in fairly high concentrations, it had not yet exceeded the toxic threshold, while Cd had approached the toxic threshold. Overall, it can be concluded that the sediment has been contaminated with heavy metals Pb and Cd but has not affected the mangrove ecosystem, and is an indication that natural filtration occurs.
