Abstract

The power requirement of ship must comply its form and principle dimension to make efficient fishing operational cost. To estimate power requirement of a ship conducted by vary approach such as Guldhamer Methods. Manual calculation by using this methods somewhat sophisticated and not practical since can only be done by certain people. Thus, to make it more simple, all the patterns are modified to be Matlab Graphical User Interface. The result shows that scoop netter power is 25,0754 HP calculated by using Matlab Application, meanwhile in the real condition the magnitude of fisher fishing vessel is 26 HP. There was discrepancy approximately about 4% where it was caused by measurement calculation in the field. Thus, this application can be used as a reference in calculation power requirement of a fishing vessel.

Abstract

The aims of this research was determined the effect of the media cork bagasse base height and a long period to transportation on mortality of common carp fry and the average live common carp at the end of rearing. Fish used is common carp fry measuring 8.5 ± 0.5 cm and cork bagasse sized average of 5 ± 0.5 cm. The method used are completely randomized designed factorial pattern 3 x 3 where the first factor was height of basic media cork bagasse (T1 = 5 cm, T2 = 10 cm dan T3 = 15 cm) and the second factor was the length of time trans-portation (W1 = 2 hours, W2 = 4 hours dan W3 = 6 hours) and repeated 3 times. The results showed that the interaction of base height of media cork bagasse and the length of time trans-portation significant effect on mortality of common carp fry. The fastest of the recovered con-scious time showed in length of time the transportation 2 hours was 2.35 minutes, and the longest was 6.56 minutes on the transportation of 6 hours. This showed that the longer the transport time then recovered conscious time of common carp fry getting longer as well. The results of the best interaction was treatment T2W1, where had not fish mortality and avearge of common carp fry that live at the end of rearing for 7 days still maximum. Packing media temperature increased over increasing transport time, but for parameter chemical physics of water during rearing was still within the normal range rearing common carp fry.

Abstract

Climbing perch is one of fresh water fish that has been started to be cultured, howeverthere are some problems occur such as low growth rate and high price of feed. Biofloc is atechnology that use bacteria which is able to destroy the waste and to maintain the water quality.Floc can be used as feed as well. This technology is capable to be applied even in the highdensity of fish rearing.T he aim of this research was to study the effect of biofloc technologyfor climbing perch culture with different densities. This research was conducted in the Muliasarivillage, Banyuasin District, South Sumatera Province since February to April 2015. TheCompletely Randomized Design (CRD) with five treatments and three replications wasapplied. The treatments were A : 100 fish/m2of density without biofloc technology, B : 100fish/m2of density with biofloc technology, C : 200 fish/m2of density with biofloc technology,D : 300 fish/m2of density with biofloc technology, E : 400 fish/m2of density with biofloctechnology. Results shown that the addition of biofloc provide significantl effect on floc, fishgrowth and feed conversion ratio. The best density was 400 fish/m2 with 5.8 mL/L of floc andfood conversion ratio 0.81, survival rate 73%, growth weight 2.77 gram and legth of 1.87 cm.
