Abstract

This study aims to determine the secondary metabolic content of saponin contained in the active fraction of sea cucumber (Stichopus vastus) by using metabolic test reagents and thin-layer chromatography (TLC) analysis. The active fraction was given the reagent in the form of HCl 2N and strong acid then continued with analysis to determine the Rf value and lieberman-burchad reaction. The results of the metabolic reaction test showed that the active fraction contained steroidal saponin compounds characterized by the presence of a stable foam and the formation of a greenish-green color. TLC analysis produced a single stain with an Rf value of 0.9 and a bluish color reaction after being given Liberman-burchad which confirmed that the saponins contained in the active fraction of sea cucumbers were steroidal saponin.

Abstract

Tsunami that swept the Tanjung Lesung coast in 2018 caused Anak Krakatau to collapse in Sunda Strait which hit the coastal areas of Banten and Lampung. Tanjung Lesung is one of the worst areas affected. Tsunami in Tanjung Lesung has taken lives, damaged infrastructure, and caused terrible natural damage. One of the damages affecting residents' lives in the Tanjung Lesung coastal community is exposure to the marine ecosystem. The main ecosystem that has the highest productivity level is the coral reef. Coral biota is the main benthic biota of reefs that are directly affected by earthquakes and tsunamis. However, until now there has been no data on the status of coral reefs after the 2018 Sunda Strait tsunami. Therefore, researchers feel the urgency of this research is high enough to determine the condition of coral reefs after the Sunda Strait tsunami in Tanjung Lesung. There are 3 research stations for data collection before the tsunami, and we conduct research in those 3 stations again after the tsunami. Then we added 3 research stations again, so there are 6 research stations. Observation of coral reefs uses the Line Intercept Transect (LIT) method. The line transect is made by stretching a roll meter with a scale parallel to the coastline along 25 meters with three replications with an interval of about 0-5 meters between replications so the total observed transect was 75 meters. The deterioration of coral reef conditions at three research stations (1-3) proved that the tsunami waves affected the damage to coral reefs. This has an impact on the diversity of coral reef species inhabitants that have decreased. Disturbance form coral-damaged structure and composition changes of the base substrate as habitat can have an impact on reef fish and coral reef inhabitants. So that this research is expected to be a reference for policymakers in determining rehabilitation steps for areas affected by the 2018 Sunda Strait tsunami.

Abstract

Laundry detergent waste is toxic and can harm the environment and aquatic life. This study aims to find out the effect of detergent waste on the growth and mortality of gourami (Osphronemus gouramy) seeds and the threshold value of laundry detergent waste that can still be tolerated by gourami seeds. This research was carried out from December 2020 to January 2021 at the Aquaculture Environmental Quality Laboratory, Faculty of Fisheries and Marine Science (FPK) University of Riau. This research method used an experimental method using a completely randomized design (CRD) method with three tests namely the preliminary test, acute toxicity test, and sublethal test. Observation of fish behavior and morphology during the test is described descriptively. In the preliminary test, the lower and upper threshold values were 10 ml L-1 and 100 ml L-1. Then in the acute toxicity test, the value LC50-96 hour was obtained at 30.1 ml L-1 with a biological safe limit value of 0.301 ml L-1. The best treatment obtained from the sublethal test was P1 with a concentration of 0.3 ml L-1 resulting in an absolute weight gain of 1.03 g, a specific growth rate of 1.56%, and a survival rate of 83.33%. The mortality rate is influenced by the concentration of detergent waste, the higher the concentration of detergent waste, the higher the mortality rate. Detergent waste that enters the waters affects the surface tension of the water so that the oxygen diffusion process is hampered, the reduced dissolved oxygen stresses the fish. Detergent waste can also enter the fish's body, irritating the gills and other organs, which can lead to death.

Abstract

Oil pollution in the waters is one of the factors that affect the abundance of fhytoplankton, especially the diatom. The waters of Lalang Strait, Mengkapan Village, are used as international shipping lanes and industrial areas. This study aims to analyze the total oil content, calculate the abundance of planktonic diatoms, and explain the relationship between the total oil content and the abundance of planktonic diatoms carried out in the Lalang Strait waters, Mengkapan Village, Siak Regency, Riau Province. This research uses survey method. Station 1 is near Tanjung Buton Port, station 2 is in the mangrove ecotourism area, and station 3 is in the fishing port and near the settlement. The result of oil content analysis obtained an average value of 0,00016 ppm. The highest oil content at station 3 is 0,00035 ppm and the lowest at station 2 is 0,00011 ppm. The results of the calculation of the abundance of planktonic diatoms ranged from 5.014 to 22.062 cells/L. The highest abundance at station 1 was 17.716 cells/L. The lowest abundance was at station 2 which was 9.694 cells/L. Simple linear regression test result, obtained equation Y= 14,2644+(-3802,27x). The coefficient of determination (R2)= 0,002 states 0,2 % of the abundance of planktonic diatoms is influenced by oil content and the rest is influenced by other environmental factors. Correlation coefficient (r) = 0,053, so the relationship of total oil content with the abundance of planktonic diatoms is very weak.

Abstract

The entry of vaname shrimp into Indonesia was to replace tiger prawns (Penaeus monodon) which at that time experienced a decline in quality. Although vaname shrimp is famous for having various advantages, there are still obstacles encountered during the cultivation period, one of which is the attack of vibriosis caused by the bacterium Vibrio harveyi. This study aims to determine the effect of adding white turmeric extract (Curcuma zedoaria) on the immune system of white shrimp (Litopenaeus vannamei) which was challenged with Vibrio harveyi bacteria. This research was conducted for 60 days from March to May 2021 using experimental research methods. The research container used a container container (size 40x30x28 cm) and a stocking density of 20 fish/container with a volume of 20 L. The research design used was a completely randomized design consisting of 5 treatments with 3 replications where P1: artificial feed + Vibrio harveyi infection, P2: artificial feed + 0.1 mL NaCl injection, P3: artificial feed + 0,5% white turmeric extract + V.harveyi infection, P4: Artificial Feed + 1% white turmeric extract + V.harveyi infection, P5: Artificial feed + 2% white turmeric extract + V.harveyi infection. The results showed that administration of white turmeric extract (C.zedoaria) with a dose of 1% gave the best results and had a significant effect on the survival rate of 68.3%, Total Haemocyte Count of 21.63x10⁶ cells/mL, and Differential Haemocyte Count (hyaline cells). by 58.7%, semi-granulocytes by 18.33%, granulocytes by 23%) which play a role in the immune system of white vaname shrimp. In addition, the value of phagocytic activity was 68.8% and was able to suppress the growth of bacteria in the intestine at the lowest at 57.7×108 CFU/mL and suppress the number of vibrios to the lowest number at 26×106 CFU/mL.

Abstract

In the Koto Panjang Reservoir, the microplastic may originate from the degraded plastic waste as well as degraded plastic net from the fish culturing cages. The microplastic may be accidentally ingulfed as fish swallowing their food. To understand the presence of microplastic present in the stomach of wild common carps living around the fish net cage, a study was conducted in December 2020-February 2021. The fish were captured using fish net (3-5 inc mesh size), 3 times, once/ 2 weeks. The fish stomach was removed and the presence of the microplastic was identified. The stomach content of the fish was mixed with 10% KOH (minimum 3 x of stomach content volume) and was incubated for2 weeks to dilute the organic materials. Then the presence of microplastic was observed using a binocular microscope. Types and abundance of the microplastic was noted. Results shown that the types of microplastic present were films, fibers and fragments. The highest type of microplastic found in the stomach of the fish was films (2.3 particles/ fish), followed by fibers (0.6 particles/fish) and fragments (1.1 particles/ fish).

Abstract

The coastal waters of Semarang Bay have been polluted by heavy metal lead (Pb). The research was conducted from September 2015 to March 2016 with 3 stations at the Tambaklorok green mussel cultivation location. Analysis of the concentration of heavy metal Pb using the AAS (Atomic Absorption Spectrophotometer) method. Data processing using SPSS and Excel. The results showed that the average concentration of heavy metal Pb in the air ranged from 0.51 to 0.76 mg/L. The average concentration of heavy metal Pb in three observations obtained an average concentration of Pb between 4.975-20.43 mg/kg. Green mussels taken in the waters were sorted and separated according to the length of the shell and weighed 1 kg each according to the length of the shell. Small (2-3 cm), medium (3-4 cm) and large shells with long shells (5-6 cm). The results of the measurement of the concentration of heavy metal Pb in P. viridis showed that the average green mussel shell size 4-5 cm at the location of station III had the lowest concentration of heavy metal Pb at 0.24 mg/kg. Meanwhile, the highest average concentration of Pb in P. viridis was found at station I at 0.89 mg/kg with a shell length of 2-3 cm. The correlation equation between shell length and Pb concentration is Y= - 0.131 + 1.13 X. Standard error of the Estimate (SEE) is 0.19. While the standard deviation of 0.20 means that the predictor variable (water) to predict the dependent variable (shellfish) is feasible because SEE is greater than the standard deviation. The average value of the Bioconcentration Factor (BCF) of green mussels is smaller than that of medium-sized green mussels and large green mussels. Green mussels can be consumed by someone if the body weight is 60 kg, then as much as 5.8 kg in a week because it contains Pb.

Abstract

Anadara granosa is one of the bivalves that are often found in public markets. This study aimed to study the relationship between length-weight and sex ratio of blood clams (A. granosa) in the coastal waters of West Rangsang. Sampling was carried out every month at three stations. Shells were collected from a 1 x 1 m2 plot on a quadratic transect. The relationship between length and weight was analyzed by regression analysis. The sex ratio between the number of female and male blood clams in each month of sampling was calculated and followed by the Chi square test to test the similarity. The results showed that the relationship between length and weight of A. granosa was positive allometric. The sex ratio of female and male blood clams in the waters of West Rangsang is not balanced. The number of male blood clams is more than the female.

Abstract

Processed fishery products produce unwanted materials, namely waste. Waste is generated in the form of heads, tails, fins, bones, and offal. Bone is one form of waste generated from the fish processing industry which has the highest calcium content in the fish body. Snakehead fish bone waste (Channa striata) is one of the potential food ingredients that is widely used in South Sumatra, especially in the city of Palembang as a raw material for processed Palembang specialties. Diversification of processed fishery products needs to be developed. In this study, the authors innovate processed products made from cork fish bones to increase the nutritional value of the community through protein and fish calcium in the form of processed products of cork fish bones chips. This research was conducted from April to June 2021. This study aims to determine the effect of using the addition of cork fish bones in the manufacture of fishbone chips with different compositions and to obtain the best chip products from the use of s cork fish bones. The method used was an experiment using a Completely Randomized Design (CRD), with 4 levels of treatment P0:0% (Without the addition of cork fish bones and 300 g of Wheat Flour) P1:20% (60 g Addition of cork fish bone and 240 g of Wheat Flour). ) P2: 25% (75 g cork fish bone and 225 g Wheat Flour), P3: 35% (105 g cork fish bone and 195 g Wheat Flour). The parameters measured in this study were organoleptic tests (appearance, aroma, taste, and texture) and proximate tests (moisture content, protein content, fat content, ash content, and carbohydrate content). The results showed that the best treatment on the P3 chips treatment: 35% (105 g Addition of Cork Fish Bone and 195 g Wheat Flour) including the best organoleptic average values ​​obtained in color (58.0) Aroma (60) Taste (52.5), and Texture (59.5). Chips P3: 35% (Addition of Cork Fish Bone 105g and Wheat Flour 195g) including proximate test, average water content is 3.09%, protein content is 18.68%, fat content is 28.81%, ash content is 6.30 %, and carbohydrate content is 43.12%.
