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

Indigenous bacteria are bacteria that naturally live freely in nature and have a variety of benefits for humans. These bacteria also have the potential to degrade pollution bacteria in the water. This research was conducted in November-December 2020. The purpose of this study was to and identify indigenous bacteria from dumai sea waters using the PCR method of 16S rRNA sequence technique. Based on the results of the study based on the analysis of 16S rRNA it is known that isolate 10 belongs to the bacterium genus Bacillus and has a homological rate of 93% with Bacillus paramycoides bacteria. Based on the phylogenic tree of isolate bacteria 10 does not have nodes associated with ten bacteria contained in NCBI. This suggests that phylogenically indigenous bacteria ISL 10 have no species similarity to the ten bacterial isolates in the phylogenetic tree, but have a similarity of base order of 93% to B. paramycoides

Abstract

Nowdays Marine pollution resulted by microplastics is a global concern. Microplastic particles have the potential to cause damage to biota. One of solution to overcome the problem of marine pollution by microplastics by applying indigenous bacteria as microplastic degradation. This study was conducted to determine the type and ability of indigenous bacteria in sediments that are able to degrade microplastics. The research was conducted from October to December 2020. Sediment sampling was conducted in Dumai Sea Waters and sample analysis was conducted at the Marine Microbiology Laboratory, Faculty of Fisheries and Marine, Riau University. Indigenous bacteria from sediments were isolated in bacterial breeding media and then tested degradation capabilities on PET plastic samples. The result of the degradation test obtained ISL8 was able to degrade the mycoplastic with a percent degradation about 7%. Molecular test of ISL8 using PCR (Polymer chain reaction) 16S rRNA method and GenBank analysis is known that ISL8 is Bacillus sp.

Abstract

One of the harmful pollutants to human health is the heavy metal Lead (Pb). A high concentration of lead that has can accumulate in the body of living things if in a long period of time. Lead concentrations that exceed the threshold in an environment can cause damage that affects aquatic biota and other living things. This research was carried out in February-April 2021. The purpose of this study was to isolate and identify bacteria that have the potential as lead bioremediation agents from Dumai marine waters. Isolation and identification of bacteria were carried out at the Laboratory of Marine Microbiology, Department of Marine Science, Faculty of Fisheries and Marine Sciences, and the lead concentration test at the Laboratory of Chemical Testing and Analysis, Department of Chemical Engineering, Faculty of Engineering. The results of the isolation on Marine Agar media which was added with Pb acetate (Pb(CH3COO2)) obtained three bacterial isolates from Dumai sea waters, namely D1, D2, and D3. The isolate that had the best growth was isolated D1. The isolate D1 was able to reduce the highest Pb concentration from 10 ppm by 80.53%, at a concentration of 20 ppm Pb, the isolate D1 was able to reduce Pb concentration by 78.8% and at a concentration of Pb 30 ppm, isolate D1 was able to reduce Pb concentration by 77.21%.

Abstract

This research was conducted in November 2020-February 2021 at the Laboratory of Fish Quarantine and Quality Control (BKIPM) Pekanbaru, Riau. The aim of this research was to test the activity of A. alba mangrove leaf extracts and stems in inhibiting the growth of pathogenic bacteria P.aeruginosa, A.salmonicida, and S.aureus. The research method used in this study is the experimental method. The sampling was conducted at the location of Marine Station UNRI Purnama Dumai. The results showed that A. alba leaf extract has the highest inhibitory power at a concentration of 100% with an average of 4.37–5.13 mm. The highest inhibitory power was against S.aureus (5.13 mm) and the lowest inhibition power was found in A. salmonicida (4.37 mm). The lowest inhibition was found at a concentration of 12.5% with an average of 0.45–0.67 mm. The stem extract of A. alba had the highest inhibitory power at a concentration of 100% with an average of 6.17–7.47 mm. The highest inhibition power was against S. aureus 7.47 mm and the lowest inhibition power was found in A.salmonicida (6.17 mm). The lowest inhibitory was at a concentration of 12.5% with an average of 1.52–2.29 mm. Based on the criteria for the strength of antibacterial activity of stem extract A. alba was in the medium category and the leaf extract was in the weak category

Abstract

Marine ecotourism is a type of tourism that involves activities related to marine activities carried out under or above the sea surface. Marine ecotourism generally covers three areas: the sea surface, under the sea, and on the coast. Marine ecotourism activities, especially beach tourism, are highly dependent on the condition of the oceanographic parameters of the region for the safety and comfort of tourists. This research was conducted in Arta Beach, Padang Pariaman Regency, West Sumatra Province, to determine the suitability of marine ecotourism at Arta Beach based on the parameters of physical environmental conditions. This study used a survey method: observation and data collection at the research location. Data analysis is used for the Tourism Suitability Index (IKW) method for physical environmental parameters and the STORET method for water quality parameters. The results of this study indicate that the tourism suitability index based on the physical condition of the environment carried out at Arta Beach at station 1 received a value of 2.49, including the suitable category, at station 2 received a value of 2.5, including the suitable category and station 3 received a value of 2.49 including the suitable category. The overall average value of IKW on Arta Beach is 2.49, included in the suitable category. This value means this beach can be used for beach ecotourism. Water quality parameters are analyzed using the storey method. The data obtained from the pH, DO salinity, and temperature parameters meet the quality requirements (good condition) and are suitable for marine tourism activities
