Abstract

Microplastics are plastic particles formed from plastic degradation to a size of <5 mm. Microplastics in waters can have adverse effects on marine organisms, aquatic ecosystems, and humans. This study aims to determine the shape, size, color, abundance, and distribution of microplastics and to determine the relationship between water quality and the abundance of microplastics in the waters of Pasaran Island. The study was conducted in November-December 2022 in the waters of Pasaran Island. Preparation and identification of microplastics in water samples were carried out in the following stages: sample preparation, organic material degradation, density separation, sample sorting, and observation of microplastic types. Data analysis was carried out using the principle component analysis (PCA) method using the Statistical Program for Social Science (SPSS) version 24 with physical and chemical parameters of the waters. Based on the study, 4 forms of microplastics were obtained, namely fiber, fragments, films, and pellets. The form of microplastic that dominated the four stations was the fiber form at 45.1%. The highest abundance of microplastics was at Station 2 (mangrove ecosystem) at 22.63 particles/liter. PCA analysis showed that the abundance of microplastics in the form of fibers, fragments, films, and pellets was negatively related to pH, salinity, current, temperature, and brightness. Increasing public awareness in reducing the use of single-use plastics and managing plastic waste needs to be done to reduce the abundance of microplastics in the waters of Pasaran Island.

Abstract

Kiluan Bay is one of the marine conservation areas in Tanggamus Regency, Province of Lampung through which dolphins migrate. This research aims to analyze the relationship between the distribution of sea surface temperature and chlorophyll with the appearance of dolphins in Kiluan Bay. This research uses an exploratory survey method. The research results show that the highest appearance of dolphins was in the Transition Season I, around 117 in the temperature range of 29,44-29,88°C with a chlorophyll concentration of 0,120-0,184 mg/m³ and the lowest in the West Season was around 31 in the temperature range of 28,56-29,34°C with a chlorophyll concentration of 0,096-0,134 mg/m³. The appearance of dolphins is more strongly related to sea surface temperature than to chlorophyll concentration because dolphins do not eat phytoplankton directly where there is a time lag where increasing the chlorophyll concentration value does not immediately have an impact on increasing the intensity value of dolphin emergence, but requires some predation time.
