Abstract

Periphyton is a sessile microscopic organisms that are able to attach in some natural subsrates such as rocks, woods, plants and aquatic animals. Research aims to determine the type and abundance of periphyton attached in ceramic substrats in the Parit Belanda River has been carried out in March-April 2016. There were 2 types of ceramics used, the rough surfaced ceramics and smooth surfaced ceramics. There were three stations namely station 1 (in the up stream), station 2 (in the middle of the stream), and station 3 (in the down stream). Samplings were conducted once/week for a 4 weeks period. The periphyton samples were brushed from the ceramic surface (8 cm x 3 cm). Type of periphyton were identified based on Bigg and Killroy (2000), Yunfang (1995), and Presscot (1974). Result shown that there were 63 types of phytoperiphyton present, they were belonged to 5 classes, namely Bacillariophyceae (13 species), Chlorophyceae (10 species), Chrysophyceae (2 species), Cyanophyceae (7 species) Dinophyceae (2 spesies) and zooperiphyton are belonged to 7 classes, namely Cilliate (2 species), Euglenophyta (5 species), Monogononta (11 spesies), Oligotrichia (2 spesies), Protozoa (2 spesies), Rhizopoda (2 species) and Rotatoria (2 species). The abundance of phytoperiphyton attached in the rough surfaced ceramic was 62,370-82,470 cells/cm2 and the zooperipyton was 9,080-53,220 organisms/cm2. While in the smooth surfaced ceramic was 80,200-101,550 cells/cm2 and the zooperiphyton was 16,720-64,320 organisms/cm2. Based on the composition of periphyton, it can be concluded that the Parit Belanda River can be categorized as eutrophic.Keywords: Parit Belanda River, Periphyton, Rough surfaced ceramic and Smooth surfaced ceramics

Abstract

This research was conducted in October to December 2016 at fish seed center Pengujan, Bintan, Riau Island. The purpose of research was to determine the best concentration of Extrajoss for improving the rate of population growth of B. plicatilis in media culture. Complete Random Design (CRD) was applied as a method at this study with 4 taraf treatments that is P0 media consists of 300 mg chicken manure, 7.5 mg TSP, 6 mg Urea, 0.45 g yeast Bread/3 liters of water (control), then for further media added P1 (0.30 g Extrajoss), P2 (0.40 g Extrajoss), and P3 (0.50 g Extrajoss) with 3 replicates and observation 2 times day. The results is there’s a population growth rate differences occurring B. plicatilis after being given by Extrajoss. The highest population density is obtained at the 6th day of observation in the media of P2 11.36 ind/ml, and the lowest population contained on media P3 Of 1.00 ind/ml, while the highest average growth rate was obtained at the treatment the P2 of 2.731 ind/ml and the lowest obtained on treatment of P3 of 1.257 ind/ml.Keywords: Brachionus plicatilis, Extrajoss, BBI Pengujan

Abstract

This research was conducted in January 2017 located in Sinaboi Village District Sinaboi Rokan Hilir Regency. The location of this study was determined purposively, with consideration of Sinaboi Village very potential with processed fish products. The data collection of this research was survey method. According to Arikunto (2012) the information obtained from survey research can be collected from the entire population and can be from only a part of the population. The surveys conducted to all populations are called population surveys / census studies, whereas if data collection is only conducted on a part of the population, it is called a sample survey. From the research there are business characteristics in Sinaboi Village has several processed products ie salted fish, shrimp crackers , And fish nuggets. The total production of all processed fish products is very large reaching 2,280Kg of production using capital of IDR.30.220.000,00 - in one production. The business age at Sinaboi Village varies but the most dominant is more than 5 years. Fish processing business that has been long standing then tend to be open to information so easy to absorb innovations related to marketing. And marketing communications that have been done by fish processors in Sinaboi Village through sales promotion, public relations, direct marketing, and personal sales. The form of marketing communication strategy suitable for salted fish processing in Sinaboi Village is through cooperatives. The strategy for fish nugget and shrimp cracker products is to use mass communication through social media. With mass communication, information will be more quickly accepted widely by all societies.Keywords: strategy, communication, marketing, processed fish

Abstract

ABSTRACT This study aimed to determine the consumer acceptance of nori added with different amounts of catfishprotein concentrate. The method used is the experimental method, and the design used was completelynon factorial random design. The treatment was the addition of catfishprotein concentrate to nori (0,  10%, and 15%). The parameters used were organoleptic value (the value of appearance, flavour, texture, and taste), and proximate composition (the content of water, ash, protein and crude fiber). The result showed that the treatment on the addition of 10% catfish protein consentrate to the seaweed (Euchema cottoni) was indicating the highest consumer acceptance.The best nori was characterized by thehighest value of sensory characteristics, those were good taste, compact texture and typical ofnori. The noricontained water 13,10%, ash 1,55%, protein 9,96%, and crude fiber 18,36%. Keywords: Fish Protein Concentrate, Organoleptic, Parameters, Proximate

Abstract

Research of toxicity of Heavy Metal Hg (Mercury) and Sublethal Test to Pangasius hypophtalmus has been conducted on October to November 2016 in Laboratory of Environmental Quality Cultivation of the Faculty of Fisheries and Marine University of Riau. The objective of this research were measured the concentrations of toxicity for Pangasius hypophtalmus in short time period in controlcondition. In this study, static 96-h acute toxicity test were carried out using Pangasius hypophtalmus as test organisms. Probit analysis using the computer software EPA and graphical method were used to calculate the 96-h LC50 depending on data suitability. Result of the 96-h LC50 and Biological Safety Level of heavy metal Hg were 0,201 mg/L and 0,00201 mg/L. The increase of heavy metal Hg (Mercury) concentrations can be low the absolute growth rate and daily of the Pangasius hypophtalmus larvaeKeywords : Toxicity, Mercury, Sublethal, Pangasius hypophtalmus.

ABSTRACT This study aimed to determine the consumer acceptance of seaweed jelly candy (Gracilaria sp) with the addition of beet extract as a natural dye, and to knowthe optimum concentrationof the extract of the beet in the best jelly candy preferred by consumers. The research method used is experimental by using non factorial complete random design. The treatment conducted was the addition of beet extract at different concentrations(0, 20, 40, and 60 %) The results showed that the addition of beet extracts affected significantly on the organoleptic valueof seaweed jelly candy. Itwas indicated that the addition of beet extract 40% is the best treatment in producing seaweed jelly candy. The characteristics of the best seaweed jelly candy were red colored, fine fibrous and chewy textured, had the beet and seaweed aroma, and the typical sweet taste of beets. This seaweed jelly candy added with beet extract 40% cantained 19.68% water, 3.30%protein, and 7.85% sugar reduction. Keywords:Beta vulgaris L, Extract,Gracilaria sp,Jelly candy.
