Abstract

The damage rate of mangrove forests in Indonesia is considered as the fastest and largest in the world. The reduced density of mangroves can be influenced by the water quality and the organic matter content around the mangrove ecosystem, causing changes in the mangrove leaves both in the shape of the length and width. This study was conducted in the mangrove ecosystem in the western part of Dumai City, with the aim of determining the morphometric size of the leaves of Rhizophora apiculata and its relationship with the content of organic matter in the sediment. The method used in this study was survey method, where observations and sampling were performed directly in the field and some of samples were analyzed in the laboratory. Mangrove density obtained from the research results ranges from 1966.66 - 4700 ind/ha, organic matter content 10.88 -17.21%. The morphometric size of the leaf length varies from 13.03 - 15.05 cm, the leaf width varies from 4.65 - 5.42 cm, and the length of the petiole varies from 1.59 - 1.91 cm. There is no significant relationship between the mangrove leaf morphometric with sediment organic matter in the studied area.

Abstract

This research was carried out in June 2023; the research location was on the coast of Kampung Beran, Tanjung Harapan, Meranti Islands Regency. This research aims to determine the type and abundance of beach litter, analyze the differences in the type and abundance of beach waste between stations, and analyze the type and abundance of beach litter between sampling times. Beach litter data collection was taken at three stations, with each station 25m in distance. Each station has three transect lines with nine plots or quadrants measuring 5×5 m2 with a distance between plots of 5m. Sampling was conducted during low tide and on weekdays (Tuesday, Wednesday) and weekends (Saturday, Sunday). Based on the research results, five types of beach litter were found, namely plastic (40%), iron/metal materials (5%), broken glass/ceramic (31%), rubber (3%), wood (11%), and others (10%). The highest abundance of waste occurred on weekdays (10,59 units/m2), and the lowest waste occurred on weekends (7,97 units/m2). ANOVA analysis and independent sample test show that the abundance of beach litter waste between stations and between sampling times did not have significant differences (P > 0.05).

Abstract

The study on carbon reserves in sediment within Pangkalan Jambi Village, Bengkalis Regency's mangrove ecosystem, was conducted from June to 2024. This research aimed to analyze carbon reserves in the sediment of the mangrove ecosystem in Pangkalan Jambi Village, Bengkalis Regency, Riau Province. The study employed field survey methods and laboratory analyses, focusing on three stations with varying mangrove densities. Results revealed nine mangrove species, dominated by Rhizophora mucronata. The average mangrove density was 2,611 individuals/ha, with a carbon reserve of 43.25 tons/ha across all stations. The study found a positive correlation (r = 0.528) between mangrove density and carbon reserves, explaining 27.98% of the total variation. Furthermore, carbon reserves showed no significant differences across sediment depths. These findings emphasize the importance of mangrove conservation for carbon storage, contributing to climate change mitigation. Further biomass and species-specific carbon storage research is recommended to optimize mangrove management strategies.

Abstract

The study was conducted in December 2022 in the Dumai River Estuary and Dumai City Mesjid River Estuary, Riau Province. The purpose of this study is to determine the amount and type of garbage that enters the sea through the estuary of the Dumai River and the Mesjid River, the difference between the amount and type of waste, and the difference between days from the garbage contained in the estuary of the Dumai River and the Mesjid River in Dumai City. The research method used is a direct survey method in the field, where data collection is carried out directly at low tide using a net stretched at the mouth of the river so that garbage is collected and trapped following the river's flow into the net. Based on the research conducted, it was found that the types of waste trapped were plastic, foamy plastic, cloth, paper, rubber, and wood. The amount of input and composition of waste in two weeks to the mouth of the Dumai River was 28,26 kg in the first week and 30,64 kg in the second week, while in the estuary of the Mesjid River, it was less, namely the first week as much as 20,59 kg, and in the second week as much as 19,44 kg. The difference between the amount and type of waste contained in the Dumai River and the Mesjid River for two weeks found that plastic waste occupied the most significant amount, namely 30,43 kg with a composition of 51,55% and 49,71 kg with a composition of 49,71% based on total waste input. The difference in waste input based on the day at the mouth of the Dumai River and the highest Mesjid River is found on Sunday, namely at the mouth of the Dumai River with a total waste of 27,79 kg and at the mouth of the Mesjid River with a total of 16,67 kg.

Abstract

Marine debris is a threat that is currently the biggest problem in the world due to the impact that trash can have on the survival of aquatic biota. This research was conducted to analyze the type and abundance and differences in the abundance of marine debris found in the northern coastal area of Bengkalis Island, Riau Province, which is assumed to be a location with the potential for accumulation of waste that could threaten the life of biota in the waters. The method used is the survey method, namely collecting data, documentation, and observation. Waste collection is carried out at three stations by determining the research location along 100 m and dividing each 20 m so there are five transects. Then, on each transect, a plot with a size of 5x5 m was made. Then, collect every type of waste contained in the plot. The results showed that plastic waste was the most common type (62%), while wood was the least found (1%). The abundance of waste on weekends is higher than on weekdays. The difference in the abundance of waste between stations was not significantly different, while the difference between the abundance of time (weekdays and weekends) was significantly different.

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.

Abstract

The entry of nutrients (nitrate, phosphate and silicate) from land-based anthropogenic activities (industry, agriculture and household waste) through rivers can potentially cause changes in water quality and will affect fertility and aquatic organisms such as phytoplankton. These three nutrients play an important role in the living tissue cells of living organisms and in the photosynthesis process. This study aims to analyze the effect of nitrate, phosphate and silicate content on the plankton abundance in the estuary of the Batang Arau River, Padang, West Sumatra. The method used is a survey method, the determination of the sampling station is done by purposive sampling, data were analysed by Excel and SPSS Software. Based on the results of laboratory analysis, the nitrate content ranged from 0,117 to 0,485 mg/l, phosphate content from 0,239 to 0,704 mg/l, and silicate content from 0,031 to 0,685 mg/l. Planktonic diatom abundance in the estuary of the Batang Arau River ranges from 194 to 750 ind/l. The results of the statistical analysis of the effect of nitrate, phosphate and silicate with an abundance of diatoms are expressed by the equation Y = 743,019 - 481,828Nitrate - 199,552Phosphate - 172,971Silicate. This equation explains that the effect of nitrate, phosphate and silicate content on diatom abundance has an inverse or negative relationship, where nitrate, phosphate and silicate levels increase, the diatom abundance will decrease. The difference of content and the relationship between parameters analyzed in this research are discussed.
