Abstract

The aim of the study was to determine the effect of using fermented feed by probiotic to the growth rate, body weight, body length, survival, feed efficiency and feed conversion rate of pomfret (Colossoma macropomum) in recirculation system. The treatment in this study was the different dose of probiotic for the feed fermentation, and the doses were 9 ml / kg of feed (P1), 12 ml / kg of feed (P2), 15 ml / kg of feed (P3), 18 ml / kg of feed (P4) and control (unfermented feed). Each treatment was repeated 3 times. The particular size of the Pomfret that were used around 5-6 cm were reared for 40 days in the tarpaulin cube tank (50 x 50 x 50) cm³ with 25 fishes/tank of fish stocking density. The fish were fed by addsatiation three times a day. The results showed that the effect of using fermented feed by probiotic significantly affected to absolute weight growth, absolute length growth, specific growth rate, food efficiency, and food conversion ratio but did not significantly affected survival rate. The best treatment was in P4 where the dose of probiotic was 18 ml / kg of feed which contributed 5.92% of specific growth rate, 8.25 grams of absolute weight growth, 2.91 cm of absolute length growth, 98.27% of food efficiency 98.27, as well as the food conversion ratio became 1.01. Meanwhile, the highest survival rate was in P3 (15 ml of probiotic/ kg of feed) which gave the 96 % of survival rate.Keyword: probiotic, Colossoma macropomun, resirculation systems

Abstract

This research aims to determine the addition of the good kinds papain enzyme for producing protein hydrolysate mackerel that has a value of precipitates and supernatant highest, the chemical content proximate of mackerel meat, protein hydrolysate, and amino acid total. The method used was experimental and composed as completely randomized design (CRD). The treatment were the used to generate the best proteins hydrolysate mackerel consisting of variety of different enzyme concentrations, namely: 6%, 8%, and 10%. Proteins hydrolysate mackerel were evaluated by precipitates value, supernatant highest, the proximate of mackerel meat and the proximate proteins hydrolysate mackerel level of water, ash, protein, fat and amino acid total. The results showed that the proximate of mackerel meat is water content 62,86 (%gw), ash content 7,05 (%dw), protein content 63,57 (%dw), and fat content 4,03 (%dw). The best kind of the concentration of the papain enzyme 10% because has the contents of presipitate 31,1 gr, the contents of supernatant 48,6 ml, but not significantly different from the value of the concentration of papain enzyme 8% of precipitate 31,4 gr, supernatant 47,6 ml. Thus, considering the use of 10% inadequate papain enzyme it can be replaced by papain enzyme concentration 8%. The result showed that the proximate from concentrate 10% is water content 86,91 (%gw), ash content 22,68 (%dw), protein content 45,30 (%dw), fat content 2,52 (%dw) and has 15 types of total amino acids consisting 8 types of essential amino acids and 7 types of non-essential amino acids, but not significantly different with treatment of enzyme consentration 8%.Keywords: Fish protein hydrolysate, Euthynnus affinis, Papain enzymatic

Abstract

ABSTRACT               This study was conducted in April 2017 by taking samples from four stations with three replications in each sampling station. The resultsof the study revealed that the highest nitrate concentrations in waters was 0,457 ± 0,2571 mg/L in Station 2, while the lowest nitrate concentration was 0,206 ± 0,0115 mg/L inStation 4. The most common planktonic diatoms species found were Isthmia sp and Hemialus sp. Linear regression analysis showed that the relationships of nitrate and  phosphate concentrations with diatom abundance  is shown as Y = 4744,7 + 5080,8x (R² = 0,1094; r = 0,330) and Y = 4767,2 + 9343x (R² = 0,0611 and r = 0,2471). Judging from the r value of those equation, the coastal waters of Panipahan can be categorized as having moderate (Nitrate) and weak (phosphate) fertility, respectively.  Keywords: Nitrate, Phosphate, Diatom Abundance, Panipahan Coastal Waters

Abstract

This study aimed to evaluate the chemical, sensory and smoking yields of cultivated catfish (Hemibagrus nemurus). The samples were the catfish at the weight of 250 gs/eachobtained from thecultivation cagesin. Kampar River in the village of Sungai Paku in the Regency of Kampar the Province of Riau. The catfish were smoked in relatively low smoking temperature in between 50-70 C for different smoking time, namely: 4, 5, 6, and 7 hours. The smoked fish were observed for their smoking yield, chemical and sensory quality. The results indicated that the highest value of smoking yield was found in the catfish smoked for 4 hours (75%), followed by those smoked for 5 hours (65,33%), 6 hours (56,66%) and 7 hours (43,46%). The highest content of fat (11,72%) and water (50,61%) were found in 4-hour smoked catfish. The highest protein content (50,59%), as well as ash content (2,47%), were found in the catfish smoked for 7 hours. Overall, the highest score of sensory value of the smoked catfish was shown by the 7 hours smoking time, at average score of (8.10), and significantly different to catfish smoked for 4 (7,07), 5 (7,44), and 6 hours (7,91).Keywords: Chemical value, Hemibagrus nemurus, sensory value, smoked fish, smoking yield
