Abstract

The research was conducted from October to December 2016 in the Kualu Nenas village, Tambang Subdistrict, Kampar Regency, Riau Province. The aim of this research was to find out the influence of biofertilizer different to increasing the benthic abundance. The method this research is an experimental method using a Complete Random Design (CRD) with one factor, four treatments, and three replications.

Abstract

Thynnichthys thynnoides (Cyprinidae) is a type of freshwater fish that inhabits the Pinang Luar Oxbow Lake. This fish has high economical value, around Rp. 25,000–35,000 /kg. This study aims to understand the reproductive biology of Thynnichthys thynnoides from the lake had been conducted during rainy season from March–April 2016. There were 169 fishes (75.04–199.32 mm TL, 3.78–73.01 gr BW, and 0.01–6.22 gr GW) were collected and measured. There were 145 male and 24 female captured. Sex ratio of males and females was 6:1. In each sampling, there were males in the 1st-5th maturity level, while that of the females were in the 1st-4th maturity level. The gonad somatic index was 0.14–14.90%. fecundity is around 26,250–33,894 eggs/fish, and the egg diameter was 0.33–0.39 mm. This structure indicate that the Thynnichthys thynnoides was a total spawner and they may spawn throughout the rainy season.Keywords : Thynnichthys thynnoides, rainy season, sex ratio, maturity level, gonad somatic index

Abstract

Snakehead fish (Channa striata) is present in the Kulim River that has relatively good water quality, as well as in the Sibam River that has polluted water. The water condition of the rivers my affects the fish health status in general. To understand the histologcal structure of gill and kidney of the fish from those rivers, a study has been conducted from Januari to March 2017. Fish organs were histologically processed and stained (HE). Results shown that in general, the histological structure of gill and kidney of fish from both areas are different. The cell structure of the Sibam’s fish shown abnormality, while those of the Kulim’s fish were normal. Cell abnormality such as hyperplasia and fused lamella in the gill and damaged glomelurus cells and nekrosis are present in the kidneyof the Sibam fish. The histological study shown that the water quality affects the structure of gill and kidney of snakehead fish from the study areas.Key word: Kulim River, Sibam River, Channa striata, Fused lamellae, Gill Structure

Abstract

ABSTRACT This research was conducted in March-April 2017 in Sasak Nagari District Sasak Ranah Pasisie West Pasaman District West Sumatera Province. This study aims to determine the gross revenues and net income of Fishing Jar. And to know the feasibility of Shrimp nets. The method used in this study is a survey method with the number of respondents as many as 30 people, where the determination of respondents conducted by census using the questionnaire that has been provided.The results of this study indicate a profitable fishing business based on Gross Income (GI) from fishing gear business Shrimp per year as much as  / 160 IDR. 64.613.000, - and net net income of Shrimp nets is IDR. 46.225.502, -per year. Based on financial analysis based on RCR calculation result of Shrimp fishing effort is 3.5 which means bigger 1 RCR> 1, then this business can be continued because it produces profit although not big. FRR with the calculation of net income per year / total invetasi times period, then obtained FRR yield 36.5% bigger than interest rate and get profit to invested. PPC for 43 trips which means the greater the value of PPC the longer the payback period of business investment or the smaller the value of PPC the faster the payback period of business investment Keywords : Business Analysis, Shrimp Nets, Feasibility Study, Sasak Ranah Pasisie.

Abstract

This research aims to see the effect of cinnamon bark submission on the quality of smoked eel during the storage. The method used in this research is experimental method. A random block design was implemented with three different treatments, they were: K0 (without cinnamon solution), K10 (with 10% of cinnamon solution), K20 (with 20% of cinnamon solution) added with salt as much as 2.5% in 30 minutes. They were kept in the room temperature for 28 days and with observation in day 0, day 7, day 14, day 21, and day 28, so the experiment unit was 3x5=15 times. The parameter examined was organoleptic (appearance, texture, aroma, taste) and chemical test (water, fat, peroxide number) along with microbiology test (total mold colonies). The result of this research showed that by soaking the cinnamon bark submission, it did not give significant effect on the appearance, taste, and texture with the accuracy level 95%. On the other hand, it gave significant effect on the chemical test (peroxide number test) and microbiology test (total mold colonies) with the accuracy level 95%. The submission of 10% cinnamon solution was the best treatment of all as its smoked eel quality had bright and shiny color. Until the final day of the storage or in day 28, those three kinds of smoked eel products were not overgrown by mushroom.Key Words: cinnamon bark, eel, smoke liquid

Abstract

A study of the relationship between oil content and the abundance of diatoms was conducted in September 2016 in the waters of Kuala Tanjung Batubara District of North Sumatra Province. Seawater samples (for oil analysis and diatoms) were collected from 4 stations. Analysis of oil content and identification of diatom was done conducted in laboratory of Chemistry and Laboratory of Marine Biology, Faculty of Fisheries and Marine Science, University of Riau. The results show that all water quality parameters measured in this study are within the tolerance range for survival of marine organisms. The oil content ranges from 0.1560 to 0.2871 ppm and diatom abundance ranges from 55 to 134 ind / l with 10 species. Based on the results of simple linear regression test, the relationship between oil content with diatomic abundance has a very strong relationship with mathematical equations y = 236,3 - 647,8x with coefficient of determination (R2) = 0,762 and correlation coefficient r = 0,873. The value of r represents a strong relationship with a negative value meaning that with increasing oil content in the waters, the abundance of diatoms in the waters will decrease.Keywords: relationship, oil content, abundance, diatoms, Kuala Tanjung.

Abstract

The aim of the research was to study on the effect of different concentrations of the extract of pandanus leaves (Pandanus amarylifollius) mixed in the seaweed (Eucheuma cottonii) drinking juice on the consumer acceptance. The method used was experimental and composed as non factorial Completely Randomized Design (RAL), which consisted of 4 levels,namely: no pandanus leaf extract (D1), the addition of 20 ml pandanus leaf extract (D2), the addition of 40 ml pandanus leaf extract (D3) and the addition of 60 ml pandanus leaf extract (D4). The parameters used were sensory evaluation, the value of pH, reduction sugar content, the viscosity, and the TPC. The highest consumer acceptance was indicated by the addition of 60 ml pandanus leaf extract (D4) into the the seaweed drinking juice. The percentage of consumer acceptance on the colour was 93.65% (75 consumer), the flavour was 73.75% (59 consumer) and the odour was 91.25% (73 consumer). The value of pH was 6.93, the content of reduction sugar was 28.85%, the value of viscosity was 3.03 cP, and the total plate count bacteria was 83x103 cfu/g.Keywords: consumer acceptance, drinking juice, Eucheuma cottonii, Pandanus amarylifollius, seaweed.
