Abstract

Plastics in the environment would eventually be degraded into plastic granules which are called microplastics. In recent years, microplastics have been spread widely not only inland but also in aquatic habitats, where averagely 5% of the plastic produced each year will end up in marine waters. The purpose of this study which was conducted in October to November 2020 was to identify the type and abundance of microplastics in the sediment as well as its possible relationship with the sediment organic matter in Dumai waters. Sediment samples were taken from Dumai coastal waters by using purposive sampling method. Identification of the types and abundance of microplastics as well as the analysis of sediment organic content were carried out in the Laboratory of Chemical Oceanography, Department of Marine Sciences, Universitas Riau. Microplastic and sediment particles were separated using 150 ml saturated NaCl solution. The types of microplastics found are fiber, fragment and films, where fiber was found to be the most commonly found (36.43%), followed by fragments (31.97%) and films (31.60%), respectively. No significant correlation found between microplastic abundance and the sediment organic content in Dumai coastal waters

Abstract

Sharks are predatory animals that dwell near coral reefs and swim at the ocean's bottom. Since the inclusion of many shark species in CITES Appendix II status in 2013, shark groups have become a global issue. This is owing to shark fishing's high exploitation, both as a target capture and as bycatch. It is divided into eleven fisheries management areas, one of which is WPPNRI 572, according to the Regulation of the Minister of Maritime Affairs and Fisheries of the Republic of Indonesia Number 18/PERMEN-KP/2014 concerning the State Fisheries Management Area of the Republic of Indonesia, hereinafter abbreviated as WPPNRI. The Indian Ocean waters west of Sumatra, as well as the Sunda Strait, are included in this area. Because it faces the high seas, notably the Indian Ocean, Sumatra's west coast is a key area of the Indonesian sea. The city of Sibolga is strategically important as one of the key entry points for utilizing the potential of western Sumatra's waters. This study was place during August and September of 2021. The goal of this study was to identify sharks landed through TPI Sibolga City in North Sumatra Province, describe their morphology and morphometrics, and describe their conservation status using IUCN and CITES criteria. Squalus chloroculus, Nebrius ferrugineus, Carcharhinus brevipinna, Carcharhinus falciformis, Carcharhinus melanopterus, Carcharhinus sorrah, Rhizoprionodon acutus, Rhizoprionodon oligolinx, and Sphyrna lewini were among the 310 sharks successfully landed in the TPI, according to the study's findings. The overall length variable has the strongest tendency, according to the results of the Principal Component Analysis Scree Plot. C. brevipinna, C. falciformis, C. melanopterus, C. sorrah, and T. obesus are shark species with comparable morphometric features. According to the IUCN, the conservation status of S. lewini is Critical or Threatened (EN). The status of N. ferrugineus is Very Vulnerable (VU). Near Threatened (NT) status for S. chloroculus, C. brevipinna, C. falciformis, C. melanopterus, C. sorrah, and T. obesus. Less Worrying Status was assigned to R. acutus and R. oligolinx (LC). While the trading status of sharks based on CITES, particularly C. falciformis, C. melanopterus, and S. lewini, are included in the Appendix II list, which denotes species that are not threatened with extinction but could be affected if trade continues without regulation.

Abstract

The presence of plastic waste in the ocean significantly impacts pollution. Lightweight plastic is transported by currents and waves, eventually accumulating in sediment. Its slow decomposition is influenced by composition and environmental conditions. Using a survey method at three stations in Padang City’s coastal waters, this study aims to investigate the composition and quantity of microplastics in sediment. Variations in microplastic levels across stations were analyzed using One-Way ANOVA, and differences between dry and wet zones and depths of 0-10 cm and 10-20 cm were examined with Independent Samples T-tests. Three microplastic categories were identified: fibers, fragments, and films, with an average concentration of 100.55 particles/kg. The Ulak Karang Beach estuary exhibited the highest particle concentration (129.16 particles/kg), whereas Banana Beach, characterized by minimal human activity, displayed the lowest concentration. There were significant differences (p<0.05) in the abundance of microplastics between stations. It was observed that the dry zone exhibited a higher concentration of particles (125.00 particles/kg) in contrast to the wet zone (76.66 particles/kg). In the 0-10 cm depth range, there was a higher abundance of microplastics (111.66 particles/kg) compared to the 10-20 cm depth range (89.44 particles/kg). The abundance of microplastics was significantly different (p<0.05) between the two coastal zones but not significantly different (p>0.05) between depths. Several possible causes of these differences were examined, but further research is needed to investigate other oceanographic factors and gain a more comprehensive understanding.

Abstract

The coastal areas of Dumai City in Riau Province are rapidly developing regions, especially in the tourism sector. This city offers several attractive beach destinations, such as Pasir Koneng Beach, Beringin Indah Beach, and Purnama Beach, attracting many local and international tourists. However, tourism growth in Dumai City also leads to an increase in solid domestic waste, which can threaten the coastal environment and the sustainability of marine ecosystems. This research aims to analyze the types and abundance of solid domestic waste in the coastal tourism areas of Dumai City. Through direct survey methods and descriptive analysis, samples of solid domestic waste were collected from three different beach locations: Purnama Beach, Koneng Beach, and Beringin Indah Beach. The results show that plastic waste is the most dominant type in all research locations, followed by wood and Styrofoam. Analysis of solid domestic waste's mass density and abundance indicates no significant difference between sampling stations or sampling times. This study provides a better understanding of the solid domestic waste issue in the coastal areas of Dumai City. It emphasizes the need for more effective management actions to maintain the sustainability of coastal tourism environments and prevent negative impacts on marine ecosystems and human well-being.

Abstract

Organic matter is one indicator of environmental fertility both on land and at sea. The content of organic matter in a certain amount can be useful for aquatic biota, but if the amount of organic matter exceeds the assimilation capacity of the waters, it can cause a disturbance. This study aims to determine the organic matter content of water and sediment at high and low tide conditions in the waters of the east coast of Bengkalis Island and to determine the relationship. The method used is a survey method that is carried out in the field directly to collect data and samples, which are then taken to the laboratory for analysis. The results showed that the organic matter content of water at high tide was 17.38-25.28 mg/L and at low tide, it was 29.63-35.55 mg/L. The organic matter content of sediments at high tide conditions ranged from 2.28-5.37% and at low tide, conditions ranged from 3.46-8.62%. These conditions indicate that the organic matter content of water and sediment has not passed the predetermined threshold. The results of the analysis of the relationship between the organic matter content of water and sediment at high tide conditions with a coefficient of determination (R2) of 0.533 with a correlation coefficient (r) of 0.730 and at low tide with a coefficient of determination (R2) of 0.713 with a correlation coefficient (r) of 0.844. The type of sediment that dominates the waters of the East Coast of Bengkalis Island is mud.
