Abstract

ABSTRACT The objective of the research was to investigate the best stock of juaro fish on closed transportation system. The method used in this research was experimental method using Completely Randomized Design (RAL) of one factor 3 treatment levels and 3 replications, ie P1: density of juaro 8 fish/L, P2:density of juaro 10 fish/L and P3: density of juaro 12 fish/L. This research was conducted in June to July 2017 in the UPT Aquatic Aquaculture Technology Laboratory of Marine Fishery University of Riau. The result of this research was obtained by optimum stocking density the transportation of Juaro fish seeds with the addition of 20 g zeolite, 10 g of activated carbon and 4 g of salt which was transported for 8 hours was 8 fish/L. It is characterized by a survival rate (SR) of 58.33%, temperature 280C, DO 2.23 mg/L, CO2 0.87 mg/L, pH 7, NH3 0.23 mg/L and post-transport cortisol blood 179,406 nmol/L. Keywords : Stock Density, Pangasius polyuranodon, Closed Transportation System,

Abstract

This study was conducted on May 2016 at Nongsa Beach in Batam City, Riau Islands Province. The purpose of study was to analise the potential of tourism in Nongsa Beach as a marine tourism. The method used in this study is a survey method. The result of the study show that Nongsa Beach has a high potential to serve as a national and international marine ecotourism. This was based on the aspects of chemical physics parameters oceanography, geology and geomorphology, climate coastal ecosystems, historical value, and overview from tour players, and the values of Pengukuran Willingness to Accept (WTA) dan Willlingness to Pay (WTP). The concept of ecotourism can be applied to develop marine tourism in the island based on the analysis of strategy of Strengths – Opportunity (SO), Strategi Weakness - Opportunity (WO), Strategi Strengths – Threats (ST), Strategi Weakness – Threats (WT).Keywords: Nongsa Beach, marine ecotourism, potential and strategies

Abstract

The research was conducted from Mei to Juli 2016 at Fish Breeding and Hatchery Laboratory Fisheris and Marine Science Faculty of Riau University. It was on to know the effect opavrim injection by different doses of the ovulation excitability, fartyliti, and the survival of larva ingir-ingir, as well as knowing which doses of ovaprim are best to produce the ovulation excitability, fertyliti, and the survival of larva ingir-ingir. It the research experiment method was applied with four treatmens and tree replications. The treatment fisiologis solution 0,9 %, Opavrim 0,5 ml/kg. 0,7 ml/kg and 0,9 ml/kg weigh of fish. The result showed that treatment with different dosage of ovaprim provide a significant influence on total of latency time of spawning, eggs ovulation/g weight of fish, eggs diameter, fertilization, egg hatchability and survival rate of larval. The best result was got from 0,7 ml/kg dosage with latency time 6,38 hour, total eggs ovulated 301/g weight of fish, accretion diameter of egg 0,026 mm, egg fertilized 68 %, egg hatchability 55,2 % and survival rate of living larvae was 67,9 %.Water quality during experiment was always in good condition for living.Keyword : Mystus nigriceps, Ovaprim, Fertility, Ovulation, Survival Rate

Abstract

ABSTRACTThe aim of this research was to evaluate sensory and physicochemical quality change of fish fillet during frozen storage. Fish sample, 800-1000g in size were taken from cage culture in Ranah County, Kampar. The fish was transported to Fish Processing Technology Laboratory, filleted, washed and stored in freezer      (-20o) for 40 days. Sensory analysis, TBA, TVB, drip loss and water holding capacity were made every 10 days along storage. During storage, sensory scores, TBA, TVB, drip loss and water holding capacity changed from 9.0-7.3, 0.005-0.334 malonaldehyde/kg, 5.36-21.36 mgN/100g, 4.16-10,40%, 83.61 - 82.35%, respectively. Based on 5 as unacceptable score, fish fillets were considered acceptable up to the end of storage. Sensory scores, TBA, TVB, drip loss and water holding capacity were highly correlated to storage time with correlation value (r) -0.9406, 0.9717, 0.9924, 0.9923, -0.9830, respectively.Keyword :Leptobarbus hoevenii, physicochemical, sensory, frozen storage

Abstract

Community structure of benthic organisms can be used as indicator to understand the quality of aquatic ecosystem in general. Siak River received many types of pollutants that mainly produced by anthropgenic activities conducted along the river bank and it may negatively affects the benthic organisms living in the river. To understand the macrozoobenthos community structure, organic matter and sediment fractions of the Siak River. There were 4 stations (St1 was in the area with no anthropogenic activity; St 2 was around the rubber factory; St 3 was around the oil processing factory and St 4 was around palm oil plantation). Samplings were conducted 2 times, April and June 2016. Samples were then identified and analyzed. Results shown that there were eight types of macrozoobenthos captured, Acuticosta sp. Tubifex sp., Bittium sp., Oncomelania sp., Tricula sp., Pila sp., Chironomus sp. and Limnodrilus sp. There was dominant species, namely Tricula sp. In all research sites, the organic matter content was ranged from 2.78 to 13.23%. In the St 1, 2 and 3 the sediment was sandy mud, while that of the St 4 was muddy sand. Based on data obtained, it can be concluded that the Siak River is heavily polluted.Keywords: Siak River, Macrozoobenthos, Organic Materials, Sediment Fraction

Abstract

A study aims to understand the condition of tofu industry waste water, the effectiveness of stabilization ponds in improving the waste water quality and the effects of discharged waste in the Tarai River, a study has been conducted on September 2016. The tofu waste was obtained from one of the tofu industry in the Tambang districts, Kampar. Wastewater was sampled from the stabilization ponds (3 sampling areas) and in the Tarai River (around 2m and 200m from the outlet and 50m before the outlet). Parameters measured were temperature, pH, TSS, BOD, COD and NH3. Results shown that the temperature decrease, from 33oC to 29.7oC, pH improved (5 to 7), BOD decreased (from 51.9 mg/L to 20.2 mg/L), COD decreased (from 2,550 mg/L to 900 mg/L, TSS decreased (from 40 mg/L to 17 mg/L) and NH3 improved (from 0.7 mg/L to 0.9 mg/L). The effectiveness of the ponds in decreasing the BOD5 was 16.1-85%, the COD was 50-76,9%, and the TSS was 50-75%. The treated tofu liquid waste that was discarded to the river slightly affects the river’s water quality.Keywords: tofu industry, wastewater, stabilization ponds, Tarai River

Abstract

ABSTRACT  Heterotrophic bacteria are bacteria that require organic carbon and inorganic nitrogen as an energy source, Research aims to determine the number of heterotrophic bacteria, knowing the results of its activity test against pathogenic bacteria (Vibrio sp, Aeromonas sp, Pseudomonas sp) and to know the species of heterotrophic bacteria through DNA test isolated from estuari waters of 15 ppt and the industrial estuary at coastal areas Sungai Kayu Ara  village with salinity 27 ppt, Siak District. Distribution of bacteria at station  higher than station 2 with value of nilai 7,04 x 107cfu / ml at station 1 to 6,46 x 107cfu / ml at station 2. Furthermore, through simple linear regression test known that the growth of heterotrophic bacteria on environmental parameters (DO, pH, temperature and salinity) categorized very weakly with the value of r = 0.10 in all parameters. Based on the antagonism test on pathogenic bacteria, it was found that there were 9 bacterial isolates that potentially inhibited the growth of the three pathogenic bacteria, namely: RM3, RM4, RM5, RM6, RM8, RM11, RL15, RL17 and RL 24 with inhibit zone ranges from 0.6 - 18mm, where the RM11 (12-15.3 mm) isolate as the best isolate in its inhibitory properties. By DNA test with 16S rRNA method and BLAST analysis, it was found that Bacillus safensis, Alcaligenes faecalis, Enterobacter sp, Enterococcus sp and Vagococcus sp species were identified as unidentified and possibly non-registered species in Genbank NCBI because it has a homology percentage of only 84%.                                                      Keywords: Heterotrophic Bacteria, Distribution, Antagonism, DNA
