Abstract

Abstract Seaweeds are very popular in the world of commerce, in science known as algae. Algae consists of four classes: Rhodophyceae (Red Algae), Phaeophyceae (Brown Algae), Chlorophyceae (Green Algae), and Cyanophyceae (Green-blue algae). Seaweed contains secondary metabolite compounds in the form of alkaloids or flavonoids that are useful as medicines and other purposes such as cosmetics and other industries. Seaweed is known to be rich in essential nutrients, such as enzymes, nucleic acids, amino acids, minerals, trace elements and vitamins A, B, C, D, E and K so it is also known as traditional medicine for cough, asthma, bronchitis, tuberculosis, abdominal pain, fever and rheumatism. This research was conducted in February - March 2018 in Sugie Village, Karimun Regency, Riau Islands Province, which aims to produce seaweed extract E. cottonii using Methanol and N-Hexane solvent and knowing LC50 value of Seaweed extract E. cottonii. Data were obtained by using BSLT (Brine Shrimp Lethality Test) method. The results of the study showed that the extract obtained from 5 kg of seaweed (wet weight) as much as 513 mL of concentrated extract. Seaweed extract with type E. cottonii was toxic to test animal A. salina. The LC50 value of E. cottonii extract dissolved in methanol was 40.2438 ppm.Keywords: toxicity, Extract of Seaweed, Desa Sugi

Abstract             This research was conducted in July on Pasir Jambak beach and processing wave and flow data in August at the Office of the Meteorology and Geophysics Agency (BMKG) Center in DKI Jakarta This study aims to wave and flow using Windwaves 0.5 software and the effect on abrasion and accretion caused by ocean waves and currents. From the results of the study it can be seen that the wave height at tide is 2 m and at low tide is 1 m in July 2018. The waters of Pasir Jambak beach have tidal patterns 2 times and 2 times recede. First tide at 05.00-13.00 WIB, first recedes at 13.00-19.00 WIB, second tide is at 19.00-23.00 WIB, and second tide is at 23.00-05.00 WIB. Meanwhile, the current speed reaches 16cm / s at station I. At station II the current speed is 12 cm / s, and at station III 10 cm / s. As a result of high waves can cause the waters to experience abrasion and accretion Keyword: Mapping, Wave, Current, Jambak Sand Beaches, Abrasion, Acceretion

                                          abstractThis study aimed to determine the effect of the use of liquid smoke with a different concentration on skipjack tuna (Katsuwonus pelamis) katsuobushi quality. The research method used was the experimental method with a non-factorial Randomized Complete Design (CRD) design with three levels namely 5% (K1), 7% (K2) and 9% (K3A) with replications three times to obtain 9 experimental units. The data obtained first is tabulated into table form and analyzed statistically by analysis of variance (ANOVA). The results showed that K3treatment was the best organoleptic treatment (appearance, taste, texture and aroma) and proximate analysis (water, ash, protein, fat and phenol). Furthermore, the results of the total microbiological test of fungal colonies in the best treatment were 3.6 x 103colonies/g. The type of fungus that grows on all products was Aspergillus sp.Keywords: katsuobushi, liquid smoke, skipjack.

Abstract

ABSTRACTIn the cultivation of soft shell crab (Scylla serrata), the duration of moulting is absolutely necessery. Moulting stimulation method of mud crab is the one way to increase soft shell crabproduction. This aims of the study was to determine the effect of eye ablation on the moulting duration of male mud crab. This study uses experimental method and Completely Randomized Design (CRD), which is 4 treatmen levels and 3 repetitions. This study uses 48 male mud crabs. Moulting stimulation methods in this study are right eye ablation, left eye ablation, right and left eye ablation and without ablation (control). Observed parameter includes length of sampling, specific growth rate, survival rate and water quality. The results showed that right eye ablation was the best treatment in accelerating the duration of moulting of 20 days, specific growth rate of 1.74%, and survival rate of 83.33%. Based on the results of the study concluded that the right eye ablation method is good to be applied in stimulating mud crab moulting in increasing the production of soft shell crab.  Keywords : moulting; ablation; moulting period; Growth; Survival Rate;Scylla serrata; Mud Crab

Abstract

ABSTRACT The study was conducted on March-April 2019,  at the Hatchery and Breeding Laboratory at the Fisheries and Marine Science Faculty, University of  Riau, Pekanbaru. The purpose of the study was to determine the effect of  guavaleaf (Psidium guajava L.)solutionwith different doses on degree of thefertilizationand hatching rateof greencatfish(Hemibagrus nemurus).This experiment used Completely Random ized Design (CRD)with four treatments and three replications. The dose of  guava leaf solution used was P1 (0 g/L), P2 (0,6 g /L), P3 (0,7 g/L) and P4 (0,8 g /L). Theimmerse green catfish eggs in  guava leaf solution for 4 minutes with a density of ± 170 eeg (0,2 g) and incubated in an aquarium. Larvae wererearing in aquarium at stocking density 4 larvae/L for 10 day. The results showed that the dose of guava leaf solution gave a very real effect to eeg fertilization rate (89,21%), egg hatching rate (84,58%) and survival rate (88,33)of larvae. The best dose guava leaf solution to increase fertility, egg hatchability and survival rate of larvae was 0,7 g/L. Keywords : Hemibagrus nemurus, Eeg Fertility,  Eeg Hatchability, Guava Leaf

Abstract

ABSTRACT  Stocking density is an important thing to consider in fish culture.Increased density affects the physiological processes and behavior of fish in their space. One of the technological innovations applied is fish farming integrated with plants through the aquaponic system. This technology, in principle, aside from saving land and water use, also improves business efficiency through the use of nutrients from the leftovers and fish metabolism for aquatic plants and is one of the environmentally friendly fish culture systems.This research was conducted on November to December 2018 in the Hatchery of TIU (Technical Implementation Unit) of Aquaculture Department, Marine and Fishery Faculty, Riau University, Riau Province.The purpose of this study was to determine the best stocking density for growth and survival rate of baung fish (Hemibagrus nemurus) in the maintenance of aquaponic systems using water spinach vegetable species, with the treatment of fish stocking densities of 20 ind./m3, 25 ind./m3, 30 ind./m3and 35 ind./m3. The size of the fish used ± 4 cm, while water spinach plants used were 9 days old.The method used in this study is an experimental method using a completely randomized design (CRD) of a factor consisting of 4 levels of treatment with 5 replications so that 20 units of experiment are needed.The results of the study concluded that the baung fish with different stocking densities had a significant influence on growth, feed efficiency, feed conversion and survival rate of baung fish.The ideal stocking density for fish is 25 tails / cm3, with absolute weight growth of 2.94 g, absolute length growth of 3.80 cm, specific growth rate of 4.89% / day, feed efficiency of 73.90%, conversion feed of 1.35 and a survival rate of 94%.Aquaponic recirculation technology is able to maintain water quality and support the selection of baung fish.Keywords: Hemibagrus nemurus, Aquaponic, Stocking density
