Abstract

High concentrations of chlorophyll-a can be used to predict where fish gather. On the other hand, tropical cyclones are one of the triggering factors for vertical stirring and upwelling that cause fertility of waters. The Sangihe Island area is not an effective area for the formation of tropical cyclones. However, due to its geographical location with a tropical cyclone area and trajectory, the potential for disturbances caused by cyclones is impactful on Sangihe Island. The distribution of wind speed, salinity, sea surface temperature and chlorophyll-a concentration can be detected by satellite remote sensing imagery. This study aims to analyze the impact of Tropical Cyclone Amang on the variability of wind speed, salinity, sea surface temperature and on the concentration of chlorophyll-a in Sangihe Island. This study useswind speed, salinity, sea surface temperature and chlorophyll-a data during the Amang Tropical Cyclone (January 6-27, 2019) from the AQUA-MODIS satellite imagery. The results show that the relationship between wind speed and chlorophyll-a concentration has impact on other parameters where both parameters showed a strong correlation value. It was also showed on the relationship between sea surface temperature and chlorophyll-a.However, the relationship between salinity and chlorophyll-a concentration showed lowest effect among those parameters.Indonesian title: Dampak siklon tropis Amang terhadap variabilitas kecepatan angin, salinitas, suhu permukaan laut, dan hubungannya dengan klorofil-a di perairan laut Pulau Sangihe

Abstract

Marine debris is one of the biggest pollution problems in the world. There are various potentials of marine and beach tourism to attract tourists, but in turn, cause a waste disposal accumulation and coupled with the built-in garbage that comes from the sea. The research was conducted at Tasik Ria Beach, Tombariri, and Marine Field Station of the Faculty of Fisheries and Marine Sciences, Sam Ratulangi University in Likupang. The aims of this study were (1) to identify the types of marine debris, and (2) to determine and compare the spatial distribution pattern of marine debris in the two designed locations. The sampling technique adapted from the shoreline survey methodology designed by NOAA was used in the study. Data were then statistically processed and analyzed using data mining software (MS Excel and Orange). This study found that the category of plastic and rubber waste is the most common category with the total amount on Tasik Ria Beach 54.39% and 97.55% in the Marine Field Station of Faculty of Fisheries and Marine Sciences in Likupang respectively. The correlation coefficient between the composition of the amount and mass of marine debris is 0.89 which indicates a close relationship between the amount and mass composition. There are many factors that cause the distribution of various types of marine debris, one of which is the activities of the people around the coastal area.Keywords: Marine debris; Category; Type; CompositionAbstrakSampah laut merupakan salah satu masalah polusi yang besar di dunia.
