Abstract

The research was conducted in June 2015 in the estuary of Kampar River of Teluk Meranti Pelalawan Riau Province. The purpose of this study was to determine the content of organic materials in sediments and abundance of macrozoobenthos. The method used in this study was a survey method. The stations was determined based on a purposive sampling which consisted of 3 stations, and each station was divided into 5 plots. The results showed that the sediment in the estuary of Teluk Meranti was dominated by sandy mud with organic materials content ranging from 1.15 to 2.08%. There were two classes of Macrozoobenthos found, Bivalves and Polychaetes with abundance 46-70 ind/m2. Its diversity index (H') was low, but high in term of dominance index (C). The uniformity index value (E) showed that species spread unevenly. The relationship between organic content and abundance of macrozoobenthos indicates an intermediate correlation with Y = 90,326-21,95x (r = 0.41, R2 = 0.1696). It seems that abundance of Macrozoobenthos in this area was more influenced by other environmental factors.Key words : Organics materials, abundance, macrozoobenthos, Teluk Meranti

Abstract

Housewives have their own potential for economic development and improvement of family nutrition. African catfish is a fish that has a savory taste and has become part of the Riau community menu. On the other hand, these fish are relatively easy to cultivate, resistant to extreme environments even in narrow areas without the need for running water. This community service activities is aimed at fostering housewives to grow African catfish in drums, make their own catfish feed and process some of their harvest. The program was held in West Minas Village, Siak Regency, Riau Province by using direct demonstration method. The participants were taught how to make fish feed, cultivation of catfish and post-harvest activities. Starting from the formation of the group and the appointment of the chairman and secretary. Followed by face-to-face counseling activities, direct practice of making fish feed, preparation of growing containers, stocking the fish fry and cultivation implementation. Every participant provided with a 200 l drum, 300 fries and some catfish feed that they produce themselves. One unit of pellet making machine was handed over to this group. Monitoring activities carried out continuously every 2-3 weeks, either through direct visits or via telephone. The participants looked serious, enthusiastic and diligent in carrying out this program. Until the end of the fish activities have been harvested and consumed by family members themselves. Viewed from the perspective of strengthening the family economy and improving household nutrition, this activity is considered quite good and is expected to be emulated by other community members.

Abstract

This community extention aimed at providing information and public awareness on the effect of environmental pollution (such as pollution of waters, soil,air and food) on local public health. As such, environmentally driven diseases could be minimized and avoided. The extention were done in desa Bukit Pedusunan, Kuantan Mudik Districtm Kuantan Singingi Regency in June-September 2021. The participants of total 35 persons, consists of local government, women group and young representative of each dusun within the village of Bukit Pedusunan. Pre-orservation were conducted to find main issue on environmental threats in the village. The extention were done through class presentation, interactive discussion and demonstration. The effectiveness of the extention were evaluated to the participants thorugh items in questionare which evaluate the change in knowledge. The level of understanding were categorize into very good, good and unsatisfied. Apparently, 28,6 % of the participants understand very good on the materials, while 45,7% categorized good and 8.6% unsatisfied. Accordingly, the extention were categorized success and showed that the knowledge of the participants increased. The impact on the implementation in the field were that of knowledge dissemination to womens group on preparation health food of fish meat base. In the future the skill were developed and become small scale household business which inturn could increase household economy.On the other hand local leader together with policy had implemented projusticia enforcement on illegal gold mining (PETI) in desa Bukit Pedusunan.In the future, it is hope that environmental condition of Danau Kebun Kopi were sustainable and could be used for tourism, water sport, fisheries and water irrigation function.

Abstract

This research was conducted in July 2020 in Pelintung Dumai Waters. The purpose of this study was to determine the relationship between total oil concentration and the abundance of phytoplankton. The method used is a survey method which is conducted at 4 stations. Based on the results of the study, the highest oil concentration was in the waters of the Pelintung industrial area (station III), namely 0.3245 ppm and the lowest concentration was in the mangrove forest area (station IV), namely 0.0738 ppm. There are 21 species of phytoplankton found in Pelintung waters. The highest abundance was found in the tourist area (station I) which was 166 ind / l and the lowest abundance was found in the mangrove forest area (station IV) which was 138 ind / l. The relationship between total oil concentration and phytoplankton abundance is negative, which means that every time there is an increase in total oil concentration, there is a decrease in the abundance of phytoplankton in Pelintung waters

Abstract

Water pollution occurs due to waste from various community activities that produce liquid, solid, and gas waste.  One of the wastes produced is heavy metals that are harmful to organisms and humans. The research was conducted in December 2020-March 2021 in the Waters of Rupat Strait of Riau Province. This study aims to analyze the concentration of Pb and Cd metals in water and blood shells (Anadara granosa), know the relationship of Pb and Cd metal concentrations to morphometric blood shells (A. granosa), and know the relationship of Pb and Cd metal content in water and blood shells (A.granosa). The method used in the research is the survey method. The results showed that the concentration value of heavy metals in seawater in the Rupat Strait Waters (Cd 0.11mg/L), (Pb 0.86 mg/L). Concentrations of heavy metals in blood shells (A. granosa) in rupat strait waters ranged Cd (0.04 mg/kg), Pb (0.03-0.06 mg/kg). Based on these results, pb and cd metal in the sea pair in the strait has passed the quality standard set while the Metal Pb and Cd on blood shells are still below the quality standard which means it is still safe to be consumed

Abstract

This research was conducted in October 2020 in the waters of Pagang Island, Koto XI Tarusan District, South Coast Regency, West Sumatera Province. This study aims to determine the condition of coral reefs and reef fish in coral reef ecosystems which were analyzed based on the coral cover in Pagang Island. The method used in this research is UPT (Underwater Photo Transect) for assessing the live coral coverage and the UVC (Underwater Visual Census) for collecting the reef fishes data. The result shows that the condition of coral reef cover in Pagang Island at all stations is in critical condition. However, the high percentage of coral dying at all stations presumed that these coral reefs were in good condition. Percentage of coral cover in the station I 4.13%, station II 6.2%, station III 1.2%, and station IV 2.07%. A total of 31 fish species belonging to 7 families with a total of 328 individuals were identified in all stations. The average abundance of fish at all stations is 0.328 ind/m2

Abstract

This research was conducted in February 2021 in the Estuary of the West Kambang River, Lengayang District, Pesisir Selatan, West Sumatra. This study aims to analyze the relationship between nitrate and phosphate concentrations with the abundance of phytoplankton in the West Kambang River Estuary. The method used in this study is a survey method. Determination of sampling stations was carried out by purposive sampling based on anthropogenic activities around the Estuary of the West Kambang River. Based on the results of the study, nitrate concentrations ranged from 0,76 ? 0,86 mg/l, phosphate concentrations ranged from 0,85 ? 0,94 mg/l, the average abundance of phytoplankton ranged from 201,50 ? 284,27 ind/l. Based on the one way Anova test, the concentration of nitrate, phosphate and abundance of phytoplankton did not differ significantly between stations. The results of simple linear regression test showed that the concentration of nitrate had a weak relationship with the abundance of phytoplankton and phosphate had a moderate relationship with the abundance of phytoplankton.
