Abstract

This research was conducted in April 2021 to analyze organic matter content in the sediment and the abundance of macrozoobenthos. The purpose of this study was to analyze the content of organic matter in sediments and their relationship with the abundance of macrozoobenthos in the waters of the Pakning River, Bengkalis Regency, Riau Province. Sediment and macrozoobenthos samples were taken from the waters of the Pakning River, Bengkalis District, Riau Province. The method used in this research is a survey method. Sampling was determined using purposive sampling at four different stations. The results of this study indicate that the organic matter content of sediment in the waters of the Pakning River has a percentage of 6.73-12.76%. The highest organic matter content is at station 1 of 12.76% and the lowest organic matter content is at station 4 of 6.73%. The highest average abundance of macrozoobenthos was 19.26 ind/m2 at station 1 with the dominant species being Anadara granosa. Connection between organic sediment and abundance of macrozoobenthos has a linear regression equation y = 1.8442 +0.1662x with a coefficient (R2) of 0.1491 which means that the effect of organic matter in the waters of the Pakning River is 14.9% while 85.1% is influenced by other factors. The value of 0.38 indicates that the relationship between organic matter and the abundance of macrozoobenthos is, a moderate relationship.

Abstract

The macrozoobenthic community structure can be used as a bioindicator to determine water pollution. The macrozoobenthic community structure consists of species, abundance, diversity index (H '), dominance index (C) and species uniformity index (E). This research was conducted in July 2020 in the waters of the North Coast of Bengkalis Island. Water parameters measured include temperature, salinity and pH. In this study, it was divided into 3 stations, namely in Selat Baru Village (station 1), Jangkang Village (station 2) and Teluk Pambang Village (station 3). The results found that as many as 34 species from 4 classes of macrozoobenthos, namely Gastropods, Malacostraca, Bivalvia, and Merostomata. Gastropod class macrozoobenthos such as Volema pyrum, Littoraria scabra, Nassarius vibra, Drupella margariticola, Pirenella cingulata, and Nerita costata; from the Malacostraca class such as Uca dussumieri, Ocypode kuhlii, Clibanarius longitarsus, and Litopenaeus cetiferus; from the Bivalvia class such as Glauconome virens, Polymesoda expansa and Dinocardium robustum and from the Merostomata class such as Carcinoscorpius ratundicauda. The macrozoobenthic abundance values ​​from the three stations ranged from 0.01 to 1.29 Ind/m2, the diversity index value (H') ranged from 2.5589 to 2.8516, the dominance index value ranged from 0.2503 - 0.3312 and the uniformity index (E ) ranges from 0.6397 to 0.6838. Water quality parameters are as follows: temperature is 29-31°C, salinity ranges from 23-28 ppt, and pH ranges from 7.5-7.9. Sediment organic matter ranged from 6.88 to 11.26% and TSS ranged from 474-542 mg/L with the dominant sediment type at the three stations, namely sandy mud. This shows that the waters north of Bengkalis Island are classified as being polluted.

Abstract

This research aims to determine the description of the presence of macrozoobenthos which is thought to have been affected by coastal stockpiling which has recently been carried out around the Mandeh Tourism Area. This research was conducted in January - March 2022, the method used in this research is purposive sampling with sampling using the transect method. The results of this study indicate that the water quality of Nagari Mandeh is sufficient to support the life of macrozoobenthos, the macrozoobenthos found consist of 10 families, namely Arciidae, Cardiidae, Cerithiidae, Fasciolariidae, Neritidae, Potamididae, Psammobiidae, Tellinidae, Turbinidae, and Strombidae. The type of sediment in the waters of Nagari Mandeh consists of gravel sand, colloid, sandy silt, silty sand, and sandy gravel. The content of total organic matter (BOT) from sediments in the waters of Nagari Mandeh was found to be in the range of 8.08% - 15.25% (medium). Coastal reclamation activities do not have an impact on the presence and diversity of macrozoobenthos but have an impact on the types of individuals living around the reclamation area.

Abstract

Organic matter has an important role in marine ecology and it can be used as an indicator of water fertility. The content of organic matter in the waters in a certain amount can be useful for aquatic biota, but if it exceeds the acceptable threshold for the environment and organisms, it can cause disturbances. The content of organic matter in the waters will increase due to waste from households, agriculture, industry, and organic waste from land that is carried into the waters. Various community and industrial activities both on land and waters in the South of Bengkalis Island can provide input of organic matter in the waters. The method used in this research is a survey method that is carried out directly in the field to collect data and samples which are then analyzed. This study aims to determine the content of organic matter in water and sediment and analyze their possible relationship. The results showed that the organic matter content of the water ranged from 34.36 – 35.96 mg/L and the organic matter content of the sediment ranged from 4.78 – 13.78%. The content of organic matter in the waters has not exceeded the quality standard threshold. The results of a simple linear regression test showed a positive relationship with an R2 value of 0.712, which means that the relationship between the organic matters content of water and sediment is quite strong (71.2%). The types of sediment in the southern waters of Bengkalis Island are the mud type.

Abstract

This research was conducted in May - June 2018 by surveying and taking a sample from Malang Rapat water on the East Coast of Bintan Island, Kepulauan Riau to determine the abundance and distribution of toxic benthic dinoflagellates associated with seaweed (Sargassum sp) and seagrass (Enhalus accoroides). Samples were taken from four sampling locations which were carried out purposively by taking into account the different anthropogenic activities that occurred in each region. The results of the study found 3 genera of toxic benthic dinoflagellates, namely Gambierdiscus sp, Ostreopsis sp, and Prorocentrum sp. The highest abundance of toxic benthic dinoflagellates associated with Sargassum sp was found in station 3, which was 302.279 cells/g, and the lowest at station 4 with (133.529 cells/g), while E. accoroides has the highest abundance at station 1 which was 620.65 cells/g). The abundance of toxic dinoflagellates in Sargassum sp has a positive correlation with nitrate concentration, but on the contrary, it was negatively correlated with the concentration of nitrate and phosphate in these waters to E. accoroides. The measured water quality parameters were still within the tolerance range for the marine organism. Further research is still needed to answer the cause of these differences and whether there are any fluctuations of abundance and the specific appearance of the toxic dinoflagellate.

Abstract

Common carp is a fish consumption that is relatively easy to cultivate since it tends to be adaptive (easy to adapt to its environment and resistant to various types of diseases). One of the protein requirements for the growth of fish seeds can be obtained from mustard greens. Furthermore, the abundant availability of mustard greens in Kajoran Village can be an alternative feed if developed as carp feed. The purpose of this study is to determine the effect of mustard greens powder on the growth of common carp (Cyprinus carpio); besides, to determine the best concentration of mustard greens powder on the growth of common carp. This study was conducted in January-February 2022. The research method used an experimental method with treatment P1 (control), P2 (mustard green powder 25%), P3 (50%), P4 (75%), and P5 (100%). The results of giving the concentration of mustard green powder for the growth of common carp show a significant difference and it can increase the growth of carp. Furthermore, the best treatment is achieved in the P3 treatment (50% mustard green powder) with an average weight gain of 1.120 g. From the results of this study, it is expected that the people of Kajoran Village can use mustard greens well for carp cultivation with a concentration of 50% pellets and 50% mustard green powder. In addition, further research is needed on the manufacture of pellets from mustard green powder to make it easier for farmers to feed.
