Abstract

ABSTRACTFish Botia is a freshwater fish that have an attractive body colors. Feeding naturallypumpkin flour feed in artificial feed aimed to improve the color quality of clown fish and how long it takes to improve the color. This research was used experimental method with quantutative approach. Research used CRD (Complete Random Design) which consists of 4 treatments with different concentration includes: P0: Positive control, P1: 10%, P2: 15%, and P3: 20%, with 3 replications in each treatments. Parameter in this research are color quality improvements, length and weight accretion.Observation data were analyzed using analysis of variance (ANAVA) α <0.05. The research result showed that feeding the pumpkin flour in artificial diet affected the color improvement of clown fish but did not affect the length and weight of clown fish. The optimal color improvement of clown fish obtained on the treatment with 15% concentration.Keywords: Clown fish, Pumpkin flour, Color quality

Abstract

AbstractThis study aims to obtain biosurfactant producing bacteria originating from the pond mud of IPAL in the palm oil industry at PT. Sawit Asahan Indah, Ujung Batu, Rokan Hulu, Riau Province. This study uses a survey method. Mud samples are taken from the Contact pond by using a sample bottle, then inserted into the cool box, then taken to the laboratory. Furthermore, 5 gramsof mud samples were weighed and sample dissolution was carried out using BPS (Buffer Phosphate Saline) media. Furthermore, this sample was enriched with BHI(Brain Heart Infusion) media, then incubated for 1x24 hours. Furthermore, this sample was diluted using 0.98% NaCl until a dilution of 10-6, and calculated the number of bacteria growing, using Petrifilm at 10-4, 10-5 and 10-6 dilutions. Then bacterial planting and purification were carried out using the media of Blood Agar and MacConkey Agar. Then, it was identified using biochemical tests andPCR (Polymerase Chain Reaction) tests. The results found 3 types of bacterial isolates with 2 biosurfactant producing species, Proteus mirabilis, and Providencia stuartii. Then it is known the rank ofDNA from bacterial species that have the highest Emulsification Index, namely 100% Proteus mirabilis.Keywords: Oil contamination, Biochemical Test, PCR test, Proteus mirabilis and Providencia stuartii

Abstract

AbstractMystus nigriceps commonly inhabit the Tarai River that is polluted by tofu industrial liquid waste. Low water quality may affects fish growth and that is reflected in the growth ring pattern of the otolith. A research aims to understand the pattern of otolith growth rings in the M. nigriceps was conducted in April to May 2019. The fish was captured  using a cast net, and a scoop net. There were  90 fishes captured (31 males and 59 females). The otolith were removed and shaved. The dark growth ring pattern was investigated using a binocular microscope. Results shown that the standard length of the fish ranged from    75.11 to 150.44 mm and their body weight was 3.27 to 44.82 g. The otolith length was 1.375 to 2.625 mm and its width was ranged from 0.85 to 1.375 mm. Among the fish captured, 82 of them having 1-3 dark rings, indicate that the in certain period the growth of fish in the Tarai River is hampered. The distance between the nucleus and the first dark ring was 0.25 to 0.625 mm and there was no special pattern in the formation of the first dark ring. This fact indicate that the first dark rings are formed individually and it is not formed by periodic events in fish life. The water quality parameter value are as follows, temperature 27-280C; pH 6;  DO 3.2-3.5 mg/L; and CO2 23.09-24.98 mg/L) and it is able to support the life of fish. Keywords: dark ring, growth ring pattern, sagita, catfish, polluted river

Abstract

ABSTRACT This study was aimed to determine the level of consumer acceptance on cookies of taro flour fortified with tilapia protein concentrate and to determine the best concentration of cookies of taro flour fortified with fish protein concentrate (FPC) from tilapia (Oreochromis niloticus). The method used in the research wasexperimentalwith a non-factorial Completely Randomized Design (CRD) consisting of 4 levels of treatment, namely the addition of  tilapia protein concentrate of 0% (K0), 5% (K1), 10% (K2), and 15% (K3). The observed parameters were proximate analysis (moisture, ash, fat, protein, carbohydrate) and organoleptic (color, aroma, flavor,and texture). The results showed that the K3 treatment was the best treatmentwith the characteristics of light brown,  odorless fish, less sweet and fish flavor, dense and crispy. Furthermore, the proximate value wasmoisture of 3,93%, ash content of 1,84%, fat content of 0,21%, protein content of 19,21%, and carbohydrate content of 72,11%. Keywords: cookies, fish protein concentrate (FPC), fortification.

Abstract

ABSTRACTThe research was conducted for 56 days , the aim to determine the effect and get the percentage fermented turi leaf (Sesbania grandiflora) Meal with Trichoderma sp. in feed on feed efficiency. This study uses completely randomized design (CRD) with one factor, with 5 treatment levels and 3 repetitions. The test feed used in this study was artificial feed with a protein content of 35% with a percentage Utilization of FTLM namely 0%, 5%, 10%, 15% and  20%. Test feed given as much as 10% of the weight of biomass per day with the frequency of feeding three times throughout the day is at 08.00, 12.00 and 16.00. The fish used in this research with in 0,99 g of weight. Fish were reaered in 15 cage units (0,5x0,5x1 m3) with the stocking density of 20 fish/m3.  The results showed that the percentage of FTLM significant effect (P<0,05) on feed  efficiency, protein retention and specific growth rate but did not significantly affect the survival rate of green catfish fingerlings. Based on the results of this study concluded that Utilization of FTLM  10% give the best respons on the feed  efficiency 43,08%, protein retention 30,10%, specific growth rate 3,86% and survival rate 96,67%. Keywords : Fermented Turi Leaf Meal, Hemibagrus nemurus, Growth, Trichoderma sp.

Abstract

ABSTRACT The aim of the study was to determine the best doses of bioboost in the biofloc system for increasing the growth and survival rate of fish seed baung(Hemibagrus nemurus).This research was conducted for 50 days from April 2 to May22 2019, in the Technical Service Unit (UPT) Hatchery and Experimental Pond of the Faculty of Fisheries and Marine University of Riau.This research was using the experimental method by completely random design (RAL) with 4 levels of treatment three replications.The treatments applied P1 = Giving bioboost 5 ml/m3, P2 = Giving bioboost 10 ml/m3, P3 = Giving bioboost 15 ml/m3, P4 = Giving bioboost 20 ml/m3. The results showed that the addition of different bioboost doses showed a significant effect (P <0,05) on absolute weight growth (Wm), absolute length growth (Lm), specific growth rate (LPS), feed efficiency (EP), feed conversion ratio (FCR) and no significant effect (P> 0,05) on survival rate (SR) of baung fish. The best treatment is giving bioboost 15 ml/m3(P3) which produces absolute weight growth of 6,01 g, absolute length growth of 5,19 cm, the specific growth rate of 1,89%, feed efficiency of 104,09%, feed conversion ratio 0,98 and survival rate 100% .  Keywords:Doses,Bioboost, Biofloc, Growth,Hemibagrus nemurus.

Abstract

                                            ABSTRACT This research was conducted on September 6, 2018. The analysis used data obtained at the Fisheries and Fish Landing Base (PPI) Tiku Agam Regency, West Sumatra Province.Aimed to study to find out the optimum fishing efforts for pelagic fish in Tanjung Mutiara waters and knowing the environmental effect on catch of gillnet and to know the environmental variable that have biggest effect. Data collection uses survey methods. The results of this study indicate the maximum production amount in Tanjung Mutiara 6923,397tons/year with optimum fishing effort 16,048 trips/year. The results of measurements on Environmental parameters during the research, obtained a current velocity between 0.1-0.2 m / s, water’s temperatures between 280C - 300C, water’s pH between 7-8, water’s transparency between 28 cm - 34 cm and water’s salinity 300/00-330/00. From the results of the multiple regression analysis, the Determination Coefficient (r2) of 0.335, which means 33.5% of the catch amount can be explained by the five environmental parameters studied, while the remainder (100% -33.5% = 66.5%) is explained by other factors. The result of the research can be explained the variable of current velocity is the most contribute to the catch  of 34.9% and the lowest contribution is salinity of 2.9%.  Keywords: fishing effort, multiple regression analysis, Tanjung Mutiara waters
