Abstract

The research was conducted at experimental pond, Fisheries and MarineScience Faculty Riau University from February to April 2014. The aim of theresearch was to determine of utilization sago lees fermentation of different levelsthat provide the best growth of baung (mystus nemurus C.V). the experiment wastdesign by completely random design and student neuman keuls to differentiateamong treatments. The treatments were applied namely ( 0, 25, 50, 75, and100%). The result indicated that different levels of utilization sago leesfermentation doesn’t have significantly effect on growth of baung (Mystusnemurus C.V). The best result was achieved by treatment A ( Non – Sago leesfermentation). Total absolute body weight of 20,62 g, Spesific Growth Rate of1,82 % /day, food efficiency of 36,09 %, while the best protein retention andsurvival rate on treatment D ( 75 % of sago lees fermentation) of 11,34 % and 95% respectively. Water quality during the research are temperature of 27 – 31 0 C,pH of 5 – 6, and disolved oxygen of 4,5 - 5,4 ppm.Keyword : Fermentation, sago lees, growth, Mystus nemurus C.V

Abstract

The research was conducted from March to April 2014 in experimental pond Fishery and Science Faculty of Riau University. The purposed of the research was to knowed the effect of different substituted fish meal with maggot meal that provide the best growth of Jambal siam (Pangasius hypopthalmus). The experiment was designed by Completely Random design with 5 substitution and 3 replication. The result indicated that differnt substitution fish meal with maggot meal doesn’t have significantely effect on growth of Jambal siam (Pangasius hypopthalmus). The best result was achived by treatment E with 100% Maggot meal level. Total absolute body weight, spesific growth rate and feet efficiency was 30,16 grams, 4,76%/ day, and 69,3% respectively, while the best protein retention and survival rate on treatment C ( 50 % of maggot meal) of 44,52 % and 70 % respectively. Water quality during the research are temperature of 29 – 30 0 C, pH of 5 – 6, and disolved oxygen of 4,5 - 5,4 ppm.Key word :Maggot meal, Fish meal,Jambal siam (Pangasius hypopthalmus)

Abstract

The experiment was conducted in November 2013 in the coastal waters ofthe Western District of Dumai. The method used in this study is a survey method,with the observation, measurement and sampling in the field. This study aims toanalyze the distribution of C. perfringens bacteria on tembakul in coastal watersof the District of West Dumai. Tembakul obtained around the mangrove forest inthe Purnama Village, which is divided into 3 stations namely Masjid estuary,mangrove forest on the Dermaga Street and Surrounding Fish Auction (TPI).Observations quality of coastal waters such as temperature, acidity (pH), andsalinity were measured directly at each sampling location. The results of thecalculation of C. perfringens bacteria analysis on tembakul (Periopthalmodonschlosseri) at three stations in the coastal waters of the District of West Dumairanged from 4.0 x 104 to 2.0 x 106 cfu / ml. Coastal waters of the District of WestDumai is still below the bacteriological contamination threshold, where theaverage total C. perfringens bacteria on fish that pass tembakul no threshold106 cfu/ml, which can lead to illness or poisoning the marine fishery products inDumai.Keywords : Dumai,Clostridium perfringens,Periopthalmodon schlosseri,Analysis

Abstract

Information about stocking densities that are ideal for the cultivation for abalone isstill very limited. This aim of the study is to determine the stocking density both in themaintenance of abalone. The benefits of this research is to provide information about thestocking density is good for the growth of the abalone and can be reference in the cultivationand further research. This study was conducted over 60 days from February to April 2014,which took place in Mariculture Center in Batam, Riau Islands Province. The method used isan experimental method with a completely randomized design (RAL) with three levels of thetreatment. Treatment 1 (stocking density of 80 animals), treatment 2 (stocking density of 90fish), Treatment 3 (stocking density of 100 fish) . Each treatment had 3 replications.Extensive research treatment of each area ith size of 50 x 35 cm2 in volume. Stocked abaloneseed size from 1.9 to 3 cm and weight from 2.04 to 2.12 g, aged 3-4 months and totaling 810tails. The best results were obtained in treatment 1 with length growth of the average size of2.29 cm to 2.98 cm and the growth of an average weight of 2.07 grams to 3.94 grams.Keywords: Abalone, stocking density, seed, growth

Abstract

This research has been done on the Bakuok Lake in Aursati Village Tambang Subdistrict District Kampar in March - April 2014. This research aims to understand the vertical profile of dissolved oxygen in this reservoir. The research used survey method. The sample’s were taken from three station and vertically in three sampling point. The parameters of water quality measured were pH, phosphate, nitrate, dissolved oxygen, free carbon dioxide, brightness, temperature and depth. Sampling vertical based on transparency, namely at surface, 11/2 Secchi depth and in the bottom of lake. The result shown the concentration of dissolved oxygen at the surface: 3,55 mg/L – 5,33 mg/L; in the 11/2 Secchi depth; 2,32 mg/L – 3,75 mg/L; and the bottom of lake: 1,78 mg/L – 2,74 mg/L. The vertical profile of dissolved oxygen showed the concentration increased with the increment of depth. The water quality parameter analyzed were temperature: 29,6oC – 30oC; transparancy 74,3 cm – 93,7 cm; depth: 208 cm – 332 cm; pH: 6, free karbon dioxide: 4,66 mg/L- 15,31 mg/L, nitrate ; 0.01 mg/L – 0.12 mg/L, phosphate: 0.01 mg/L – 0.17 mg/L and phytoplankton ranged from 20.415 sel/L – 39,509 sel/L. The concentration of dissolved oxygen in Bakuok Lake showed the highest decrement, in a general the parts quality still support the aquatic organism life.Keywords: Dissolved oxygen, the vertical profiles, Bakuok Lake

Abstract

This study was conducted in September-December 2013 in the factory know which is located on Jl. Build Kubang Kingdom Village Tarai Mining District of Kampar district in Riau Province. The purpose of this study was to determine the effectiveness of a decrease in TSS and ammonia wastewater know. The decrease in the concentration of TSS and ammonia made with plastic bottles of media biofilter system anaerobic-aerobic process plastic scrap plastic pieces containing medium and without (controls). Then proceed with the process of phytoremediation by water hyacinth and without media. The combined performance of the biofilter and phytoremediation of media is very effective to reduce the concentration of TSS and ammonia. This is evident from a decrease in the effectiveness of the TSS concentration during the observations ranged from 66.38 to 90.82% with an average concentration at the inlet of 411.4 mg / l to 57.2 mg / l. While the effectiveness of the reduction in ammonia concentrations ranged from 54.74 to 92.56% with an average concentration at the inlet of 13.16 mg / l to 4.28 mg / l. For other parameters also are in accordance with the quality standards that have been established, such as pH 7, temperature 28 0C, and DO of 3.76 mg / l. Further tests of the survival of fish and tilapia on the marsh Sepat wastewater that has been treated with a biofilter media and plastic bottles of water hyacinth respectively reached 87% and 70% except 47% of fish monitored.Keywords: Biofilter, phytoremediation, wastewater

Abstract

This research was conducted in October 2013 in Pematang Sei Baru village Tanjung Balai Asahan sun district Asahan regency in North Sumatera Province. This study aims to determine the level of environmental friendliness sembilang gear nets using tuasan, feasibility as well as factors related to the arrest of environmentally friendly technologies. The method used in this study is a survey method with direct observation and interviews and discussions with fisherman. Observation made by FAO (1995) shows that fishing gear including nets sembilang use tuasan into environmentally friendly fishing gear. The results of the feasibility analysic calculations indicate that nets fishing effort Sembilang using tuasan provide benefits for fishermen and deserves to be developed because of the value of BCR (Benefit Cost Ratio) retrieved of 1,3 FRR (Financial Rate of Return) is 28,78% and PPC (Payback Period of Capital) is 3 years 4 monthsKey words : Jaring Sembilang, Technology, Selectivity, Business Feasibility, Pematang Sei Baru
