Abstract

AbtracTSS (Total Suspended Solid) is suspended materials has a negative impact on water quality because it reduces the penetration of sunlight into the water body, the turbidity of the water increases which causes growth disruption for the producer organism. This research was conducted in April 2018 in the West Rangsang waters of Meranti island regency. Aimed to determine the distribution of the concentration of TSS during the West and East season by using Landsat 8 Acquisition image analysis in March 2018 and Landsat 8 Acquisition june 2017. The research method is a survey and determination of sampling points by means of purposive sampling. TSS in situ analysis was carried out in the sea chemistry laboratory by gravimetric method, and analysis of image data using ER Mapper 7.0 and Notepad++ applications. Analiysis of insitu TSS data at each station was obtained with a range of 65.4 – 115.8 mg/l, from the results of image processing in the western season obtained TSS values of 0 – 109 mg/l and the results of image processing in the East season obtained TSS values of 0 – 120 mg/l. In general, the TSS distribution patterns generated by the image in the West seasen spread of TSS which leads close to the coast tends to be higher than the TSS distribution in the East season and vice versa the more towards the sea the TSS concentration is lower.The result of TSS data in situ with the result of image analysis in the West and East seasons of the stations in the West season in higher than in the East season.The result of current velocity measurement is 0.22 – 0.55 m/s, visibility 6.5 – 38 cm, turbidity 43.23 – 225 NTU, salinity 25.01 – 28 ppt and depth of 3.5 – 5.11 m. Keyword: TSS, Rangsang Barat, ER Mapper, Notepad++,Landsat.

Abstract

ABSTRACTThis research was conducted in April until May 2018, at the Laboratory of Aquaculture Technology, Faculty of Fisheries and Marine, University of Riau. The study aims of to influence the addition of astaxanthin in artificial feed to increase the color quality of Tiger Barb (Puntius tetrazona) and get the best dose of astaxanthin. This study uses an experimental method with a completely randomized design (CRD) of one factor with 4 treatment levels and 3 replications. The dose of astaxanthin in the treatment were: 0% astaxanthin, 1% astaxanthin, 3% astaxanthin, 5% astaxanthin. The size of fish was used is 3-5 cm with 10 stocking densities per aquarium. Maintenance lasts for 30 days and feed is given as much as 3% of the weight of biomass, the frequency of feeding is 3 times a day. Parameters observed included fish color, absolute length growth and absolute weight, survival rate and water quality. The results showed that the administration of astaxanthin had a significant effect on changes in the quality of the color of the Tiger Barb. The best treatment was at a dose of 5% which improved the quality of chest color 12.77, body 9.16, tail 14.00. The best absolute length growth is 0.55 cm, absolute weight is 0.47 grams and fish life is 100%. Keywords: Astaxanthin; Color; Tiger Barb; Puntius tetrazona

Abstract

ABSTRACT This research was to determine the effect of the addition protein concentrates from different types of catfish (P. hypopthalmus, C. gariepinus and P. albilabris) to consumer acceptance of bread. The method used is an experiment using non-factorial completely randomized design (RAL), with 4 levels of treatment namely K0 (control), K1 (addition of  Shark Catfish  KPI), K2 (addition of Walking Catfish KPI), K3 (addition of Eel Tailed Catfish KPI) respectively 50 g. The parameters measured in this study are organoleptic test and proximate analysis including water, ash, protein and fat content. The results showed that the addition of KPI 50 g was the best in K1, with an organoleptic appearence (3.38) with characteristics yellow and there were red spots on the surface of fresh bread, flavor (3.47) with the characteristic taste of plain bread and the fish feels a little, aroma (3.31) with the characteristic aroma of fresh bread and a little fish smell and texture (3.32) with the characteristics of a soft and elastic texture. Based on proximate analysis, plain bread with the addition ofShark Catfish  KPI has a water content of 33.86%, ash content of 0.66%, protein content of 16.30% and fat content of 4.56%.Keywords :C. gariepinus,Fish protein concentrate, Fresh bread, P. hypopthalmus, P. albilabris

Abstract

ABSTRACT    Feed is one of the major operating in cultivation of mud crab (S. serrata).One aspect for attention in cultivation were feeds. This research aims to determine the optimal effect of the feed percentage on the growth of mud crab aquaculture(S. serrata).This research was conducted using Experimental Methods with completely randomized design (CRD), those is 4 treatments and 3 replications. Treatment A (3% feeds of the weight biomass), B (5% feeds of weight biomass), C (7% feeds of weight biomass feed, D (9% feeds of weight biomass).Animal testing used was mud crab (S. serrata) with an average initial weight of ±100 gr / individual.Animal testing used were 48 crabs and maintained in a plastic basket measuring (59 x 37 x 17 )cm3during 40 day. The results shows different feed percentages had a significant effect (P <0.05) on absolute weight growth, feed conversion, livelihood, moulting, but not significantly influence (P> 0.05) on SR mangrove crabs. The results shows that the best treatment for absolute weight growth was found in 7% feeding of biomass weight (P3), which was 80.00 g, specific growth rate of 1.53%, average moulting time of 18.66 days with survival rate 83 , 33%, and the best feed conversion is 4.10.Keywords :Mud crab; Food; Growth; Moulting; Life-long rate

Abstract

ABSTRACTThis research was conducted in Agustus to September 2018 in the Aquatic Aquaculture Technology Laboratory of Marine Fishery University of Riau. The aims of this research was to determine the growth and survival rate of Channa striata with different feeds. This research used a size aquarium 40 x 30 x40 cm3 with a waterin hight 10 cm for 12 units. The feed used in the form of Pellet, Earthworms, Blood worm, and Tubifex sp. given with dose of 60% from the body weight of thefish. The method used in this research was the experimental method of Completely Randomized Design (CRD) using one factor with 4 treatments and 3 replications. The best treatment result is feeding with Tubifex sp which can produce absolute weight growth rate (1,48 gram), absolute length growth (3,7 cm), growth of specific length (5,45%) and survival rate (97,22%). Water quality during the research was obtained of pH 6.0-7.0, temperature 26-28 0C, DO 3,9-5,4 mg/L and ammonia 0,01-0,05 mg/L. The result of research with different feeding significantly affected the growth of Channa striata, but did not significantly affect the survival of Channa striata. Giving Tubifex sp. is the best feeding to increase the growth of Channa striata. Keywords : Tubifex sp, Channa striata, Growth and survival rate.

Abstract

AbtracThe study of the distribution of sedimentary characteristics in Ulakan Tapakis waters aimed at sediment deposition environmental conditions based on sedimentary characteristics. Sediment sampling was conducted at nine sampling points using purposive sampling technique.Analysis of the sediment fraction was carried out using the wet sieveand pipette methods. The results of the study the Ulakan Tapakis waters had 4 types of sediment namely: sand, muddy sand, sandy mud and mud,which is dominated by sandy mud. The sedimentary statistical parameters showed the value of mean diameter (mean size) range from 0,23-5,73ø with the clasification of coarse sand to medium silt. Skewness values range from -0,90-0,42ø with the clasification of  very negative skewed to very positive skewed. The values of sorting ranges from 2,04-2,53ø with the clasification of very poorly sorted. The value of kurtosis range from 0,47-9,31ø with the clasification of very platikurtik to leptokurtik extreme, indicate the waters under the influence of current conditions that tend to be unstable and the number of anthropogenic aktivities. Keyword: Sedimentary Characteristics, Sediment statistics, Ulakan Tapakis
