Abstract

Aquaponics, the combined culture of fish and plants in recirculating systems,hasbecome increasingly popular. Ammonia that excreted from fish metabolic activity is aserious problem in intensive aquaculture production systems because it would build-upto toxic level in fish tanks. Therefore, recirculating system with filtration process be-comes an important component to maintain water quality in order to be an appropriatecondition for fish production. The purpose of this study was to develop a silais (Ompoksp) by increasing production capacity with intensive Aquaculture of high density ismaintained in the media filter reisrkulasi Chinese Cabbages (aquaponics system). Theresult of the experiments showed silais fish farming (Omphok sp) aquaponics system toincrease production capacity to produce biomass of fish silais to 0.878 kgs and Chi-nese Cabbages up to 1.161 kgs and fish performance of that system such as survivalrate and food conversion ratio, were higher than the others, i.e., 100 % and 1.24, re-spectively. However, fish specific growth rate of the treatment (2,15 %) have no sig-nificant difference (P> 0.05) compared to other treatmen.

Abstract

The research was conducted from April until June 2012 at Soil and Water Quali-ty Management Laboratory Fisheries and Marine Science Faculty of Riau University.The aim of the research was to know chemical and physical characteristics of pondbottom soil and profiles of PMK soil as potencial to development fish pond. The meth-od used was experimental and make up profiles in four lokation.Characteristics of fish pond bottom soil showed relatively acidic soil (PodsolidRed Yellow) with pH ranging from 4.9 to 5.7, the medium to hight levels of organicmatter (1.56 to 2.21%) and low of total N and CEC. Some locations are potentialenough to build a fish pond, although still need to achive pond bottom soil primarilyuse agricultural lime and organic matter to increase of on CEC and the productivity offish pond.

Abstract

The objective of this study was to evaluate the quality changes of instan brownrice porridge fortified with catfish protein concentrate during storage. Instant brownrice proridge was prepared from glutinous red rice flours (33%), skim milk (50%);corn oil (2%); sugar (5%) and forfified with 10% catfish protein concentrate. Theproduct was stored at room temperature for 45 days. Sensory analyses, peroxide,totalbacterial count, Escherichia coli, Staphylococcus aureus, and mold were made every0, 15, 30 and 45 days. The result indicated that the quality of porridge decresed duringstorage. The sensory value, peroxide, total bacterial count, Escherichia coli, Staphylo-coccus aureus and mold of the porridge at initial to the end of storage was 3, 59 - 3,30; 0 - 9,6 meq/1000g; 2, 0 x 103 - 1, 0 x 104 Cfu/g; 0, 2 x 102 - 1,0 x 102; 0, 15 x 102 –1,0 x 102 koloni/g. The was no mold growth identified during storage.

Abstract

The study aims to assess the development and fisheries subsector contribution tothe economy (GDP) Rokan Hilir district. In order to achieve these objectives, the an-nual data collected (series) GDP and fisheries data Rokan Hilir district during the peri-od 2006 to 2010. Based on these data, the fisheries sector contributed 21.62%. Andseen his contribution to the fellow agriculture, fisheries subsector is the largest contrib-utor (41%) among the other sub-sectors (crops and hotikultura, tree crops, livestock,and forestry). Fisheries in Rokan Hilir district dominated by fishing in the ocean. Fish-eries production in 2010 was recorded 59808.43 tons, up from the previous years pro-duction. The increase in production occurred primarily in aquaculture production.

Abstract

This study aims to determine the best stocking solid in the gonad maturation of Tricho-gaster leeri Blkr in cages placed in ponds. Cage size used is 1 x 1 x 1 m were placed in thepond Fisheries and Marine Science Faculty, Riau University with a solid stocking respectivelyP1 = 30 fishes/cage, P2 = 40 fishes/cage and P3 = 50 fishes /cage. The fish were reared for 6(six) weeks, during maturation of fish feed shrimp pellets + vitamin E. Maturation observa-tions conducted each week by taking 20% of the samples. Parameters measured were maturitylevel, gonado somatic index (GSI), fecundity, egg diameter, semen volume, and mortality.The results showed that the best treatment was P1 = 30 fishes/cage produce attainment gonadmaturation (TKG IV) was 2 fishes, gonado somatic index (GSI) was 8.36 %, fecundity was1004 eggs, egg diameters was 0.66 mm, semen volume was 0.0173 ml and mortality was 2fishes.]

Abstract

Survey of coral reefs ecosystem was conducted around Kasiak Island waters,about 3 mill in front of Pariaman City, West Sumatera Province in July 2011. The aimof this study is to find out the effect of earthquake in 30 September 2009 to the condi-tion of coral reefs in Kasiak Island, which was occurred in the waters around 5 km infront of Padang City. The earthquake had affected in the big scale to the buildings inPariaman and Padang City, and caused many people was killed. However, from theresults to the coral reef kondision araoun Kasiak Island showed that no effect of theearthquake to the coral reef ecosystem. Then, condition of coral reefs is very good in 3m dept of the island, however their condition is very different with the deeper waters(7 m dept).

Abstract

A good designer of fishing vessels must be able to estimate ship resistances which treat-ment on ship during fishing operations. Such resistances information will be used as themilestones in the main and the auxiliary engine matching in which the chosen engine must besuitable to the needs of thrust at the certain velocity. The magnitude of ship resistance can bedetermined by some methods e.g. towing tank methods, using ship resistance graph of seriesship models on various velocities, using approaching formula from statistic (with regression)and the last by using Computational Fluid Dynamics (CFD). CFD is the most economic inship resistance study with result almost approaching the manual test. The ship was gillnetter 5in gross tonnage. Its model was investigated by using numerical simulation of CFD. The dataof resistance are processed with ANSYS CFX version 14. The result shows the vesselresistance was 6,43 kN and engine power was 29,76 kW at maximum speed (9 knots). Itimplys the similiar conclusion by using manual test and approaching formula.

Abstract

This research was conducted in December 2012 with tuna longliner as the objectin which designed operated in Bungus Waters, Province of West Sumatera. The objectof the research was the review of previous reseach with optimatized main dimensionnamely LWL = 29,27 m, LPP = 28,14 m, B =6,40 m, H = 3,57 m dan T = 2,87 m. Theaim of this research is to calculate tuna longliner stability by inputting main dimension,form coefficients, and various other additional paramaters. Its value was entered toequations of stability calculation so that resulting a value that will be checked its statustowards stability criterion according to IMO. Calculation result conclude that tunalongliner stability satisfy IMO criterions.
