Abstract

ABSTRACT This research was carried out on June 4 to July 13 2018 which was held at the Regional Technical Implementation Unit Pond of Fisheries and Marine Faculty, Riau University, Pekanbaru.This study aims to determine the addition of the best probiotic doses to the feed in increasing the growth and survival rate of  Hemibagrus nemurus with aquaponic technology. The method used in this study is an experimental method using a single-factor completely randomized design with five treatment levels and three replications. The treatments were :1) 0 ml/kg of feed (control), 2) 2 ml/kg of feed, 3) 4 ml/kg of feed, 4) 6 ml/kg of feed and 5) 8 ml/kg of feed.The results of the 40-day study found that the best treatment was 6 ml/kg of feed which gave absolute weight growth of 6.26 g, absolute length growth of 4.12 cm, daily fish growth rate of 1.15%, feed conversion value of 1, 03 and the survival rate of 93.33%. The results of measurements of water quality during the study were temperatures of 25 - 310C, dissolved oxygen from 4.3 to 6.5 mg/L, pH 6-7, ammonia 0.16 - 0.26 mg/L.  Keywords: Aquaponics, Hemibagrus nemurus,Probiotics,  Growth

Abstract

Abtract The study aimed to determine the effect of the addition of the commercial papain enzymes and papaya leaves on the quality and characteristics freshwater scallop sauce. The research was carried out by using the experimental method, by conducting experiments on making of freshwater scallop sauce by adding commercial papain enzymes and papaya leaves. The experimental was designed as the non-factorial Completely Randomized Design (CRD). The treatment given was consisted of 3 levels namely P0 (control), P1 (addition of commercial papain enzyme), P2 (addition of papaya leaves), for 3 replications. The result showed that the addition of commercial papain enzymes and papaya leaves significantly affected to the taste, flavor, protein content and NPN values, but did not affect lactic acid bacteria. The freshwater scallop processed by addition of papaya leaves (P2) was producing the best quality of the scallop sauce, which was shown by the highest organoleptic value. The value of taste was 7.2 with characteristics tasty and quite salty as specific scallop sauce taste, but papaya slightly tasted. The value of aroma was 6.8, characterized by the specific aroma of fermented fresh scallop. Meanwhile, the highest content of protein was produced by the control treatment (P0) at 2.99 %, the highest content of non-protein nitrogen was produced by treatment of the addition of commercial papain enzyme (P1) at 0.74 %, and the highest number of lactic acid bacteria was shown in the product treated by the addition of papaya leaves (P2) at 6.7Keyword: characteristics, enzyme, papain,Pilsbryoconcha exilis,sauce

Abstract

ABSTRACTThis study was aimed to determine the effect of temperature and boiling time on the quality of katsuobushi skipjack (Katsuwonus pelamis) based on organoleptic test (appearance, aroma, texture, taste), proximate analysis (water, protein, ash, phenol, pH value) and microbiological test (Total Plate Count, fungi identification). The experimental design used in this study was a two factorial Completely Randomized Design (CRD) consisting of boiling temperature with 3 treatment levels, namely 70-80oC (S1), 81-90oC (S2), 91-100oC (S3) as the first factor, and time with 2 treatment levels, namely 30 minutes (L1) and 60 minutes (L2) as the second factor.

Abstract

ABSTRACT             The study was conducted on 11 July - 20 August 2018 in the Laboratory of Fish Breeding and Breeding at the Faculty of Fisheries and Marine Sciences, University of Riau, Pekanbaru. The purpose of this study was to determine the effect of the type % Tubifex (fresh, frozen and dry) and water change rate (L / minute) (debit) on the growth and survival of sheat fish larvae (Ompok rhadinurus) feed in recirculation system for 40 days. The method used is a Factorial Complete Random Match (RAL) with two factors, namely the first factor in the form of feed with three levels each Tubifex fresh (Ts), frozen Tubifex (Tb), dry Tubifex (Tk). While the second factor is the water debit of each D1 (1 liter / minute water debit), D0.5 (0.5 liter / minute water discharge). To minimize errors, each level of treatment was repeated 3 times. The best growth rate in the treatment of Ts D1 (Tubifex fresh with 1 liter / minute water discharge) with an absolute weight of 7.85 gr, absolute length 10.11 cm, average growth rate of 18.23% / day, and survival rate 94.44. The condition of water quality is the water temperature 27-280C, pH 5,6-5,7 and dissolved oxygen 5,6-6,1 mg / l. Keywords : Ompok rhadinurus, Type %, Tubifek sp, water

Abstract

                                        ABSTRACT This research was conducted in January 2018 in the Dumai sea waters of Riau Province with the aim to determine the oil content in sediments, the abundance of macrozoobenthos, and the effect of oil content on sediments on the abundance of macrozoobenthos. The research location is divided into 5 stations, from each station consisting of one transect line and each transect line consists of 3 plots (1m x 1m). Taking sediment samples using a pipe (pvc) while taking macrozoobenthos samples with the help of a small shovel. The results of the study obtained an average oil content in the sediment of 73.86 ppm. The abundance of macrozoobenthos varies per station with a range of 35,00 ind/m2– 69,33 ind/m2. The macrozoobenthos species found consisted of 15 species with phyla, and 5 classes. The relative abundance value of macrozoobenhtos varies from 2,88% to 24,79%. Based on simple linear regression, the effect of oil content on sediments on the abundance of macrozoobenthos is very strong (R2= 0,761); (r) = 0,87. The abundance of macrozoobenthos is influenced by the oil content in the sediment of 76,1% and the rest is influenced by other factors such as predators, competition, and food reserves. Keywords: Pollution, Macrozoobenthos, Sediment oil content
