Abstract

ABSTRACTPilsbryoconcha exilis,a type of mussel, was commonly found in ponds and rivers of Sungai Paku Village, Kampar District, Riau Province.This research wasaimedto evaluateand to compare the proximatecompositionof  themusselcollected from rivers and ponds.The used method in this researchwas a survey method with randomsampling that wascollectedfrom rivers and ponds.The protein, moisture, water, ash, and carbohydrate of the mussel meat collectedfrom rivers consecutively were 14.29%, 0.56%, 78.21%, 1.26%, and 5.68%.Furthermore, the protein, fat, moisture, ash, and carbohydrate ofthe mussel collectedfrom ponds consecutively were 15.36%, 1.65%, 79.85%, 2.54%, and 0.6%. Based onthe results of the proximate analysis showed a significant difference with a different environment to the mussel of proximate content.Keywords:Pilsbryoconcha exilis, pond, proximate,river.

Abstract

ABSTRACTSail River is one of the rivers in the city of Pekanbaru that has been polluted with organic pollutants. This study aims to determine the decrease in TOM and BOD levels by using different bioijuk densities. This research was carried out on the Sail River, in March-April 2019. The method used was an incomplete design (CRD), with 3 treatments of bioijuk density namely P1 (low density), P2 (medium density) and P3 (high density), and each -one with 3 replications. The sampling location was selected in the inlet section (before passing bioijuk) and the outlet section (after passing bioijuk) artificial ditch. The results showed that the highest decrease in TOM levels occurred in P2 (0.046 mg / L) with a decrease in effectiveness (EP) of 95%. The highest decrease in BOD levels was found in P2 (4.66 mg / L) with an EP of 53%. It turns out that the treatment of different bioijuk densities does not have a significant effect on decreasing levels of the TOM and BOD of the Sail River.Keywords: Bioijuk, TOM, BOD, bacteria, effective sperm

Abstract

Abstract The butchery liquid waste is rich in nitrate and phosphate and it need to be processed before being flown to the environment. To understand the effectiveness of combined anaerob-aerob biofilter in reducing the nitrate and phosphate content in the butchery liquid waste, a study was conducted in  March – April 2018. The waste (315 L) was treated using a batch system that was consisted of 2 aerob and 2 anaerob tanks. The butchery liquid waste was kept for 10 days in anaerobtanks, 7 days in aerob tanks. By the end of the experiment, the nitrate reduced from 39 mg/l to 12.4 mg/l (the effectiveness was83.21%). While the phosphate reduced from 15.4 mg/l to2.9 mg/l (the effectiveness was 81.16%). Other water quality parameters such as pH was normal and DO was improved (from 1 mg/L to 5 mg/L). The treated waste was used as a mediafor culturingH. pluvialis. Observations of H. pluvialiswere conductedfor 8 days. The H.pluvialis density peaked by the 6th day, it was963,33 cells / ml.  Based on data obtained, it can be concluded that the useof anaerob -aerob biofilter was effective forimproving the butchery waste water quality . Keyword : Organic waste, Anaerob tank, Aerob tank, Haemotococcus pluvialis

Abstract

Abstract Pangasius hypophthalmus is a type of freshwater fish that inhabit the Sail River that is polluted and the Tapung Kiri River that has relatively good water quality. As the water quality in general affects the blood condition of the fish, it is predicted that blood condition of P. hypophthalmus from the Tapung Kiri River and the Sail River different. A research aims to understand blood condition of P.hypophthalmus from both areas has been conducted from February to March 2019. There are 12 fishes from the Tapung Kiri River and 12 fishes from the Sail River. The fish blood was taken and analyzed for erythrocytes and leukocytes content, hematocrite and leucocrite levels and types of leukocytes present. Results shown that the erythrocytes, leukocytes, hematocrite and leucocrite of fish from the Tapung Kiri River was 2.620.833 cells/mm3, 242.958 cells/mm3, 35,6% and 1,54% respectively. While those of the Sail River was 1.887.500 cells/mm3, 310.500 cells/mm3, 28,75% and 2,62%. In the fish from both areas, there were 5 types of white blood cells.  In the fish  from the Tapung Kiri River, there were lymphocytes 85,6%, monocytes 2,9%, thrombocytes 9,7%, eosinophils 0,8% and neutrophils 0,8% respectively. While those of the Sail River were lymphocytes 56,3%, monocytes 5%, thrombocytes 37,1%, eosinophils 0,8% and neutrophils 0,8%. Based on data obtained, it can be concluded that the fish from the Tapung Kiri River is healthy while the fish from the Sail River is not healthy. Keywords: blood, erythrocytes, leukocytes, hematocrite and leucocrite

Abstract

ABSTRACTThe research was aimed to observe the using of papain enzyme to remove the limelayer from the skin of sea cucumber (Holothuria scabra) by applying boiling method. The research was using an experimental method and composing  as nonfactorial randomized completely design. The treatment conducted was the using of papain enzymes at different concentrations(0, 0.05, 0.1, and 0.15 %) and  boiled at the temperature of 60oC. The parameters used were sensory evaluation, included the value of texture and aroma, the content of calcium, and the proximate composition. The results showed that the use of the papain enzyme wasaffecting to the removal of lime layer from the skin of the sea cucumber, indicated by the significantly different of the appearance and the texturevalue, and the calciumcontent, but not affecting to the aroma value. The proximate composition showed that the content of water 83.32% wb, ash 20.26% db, fat 10.76% db, carbohydrate (by difference) 7.10% db, and protein 80.06% db. Keywords: Papain enzyme, limestone layer, and sea cucumber

Abstract

ABSTRACT This research was conducted in May to June 2018 at the Fish Seed Hall Laboratory (BBI) headland of the Fisheries and Marine Service, Rokan District, downstream. The purpose of this study was to determine the efficacy of ovulation and hatching of fish eggs (Ompok Rhadinurus) which were injected with a combination of the hormone ovaprim with oxytocin at different doses. The method used in this study is the experimental method that uses one-factor Completely Randomized Design (CRD) consisting of five treatments with three replications. The treatments applied in this study are: P1: Injection with 25% ovaprim + 75% oxytocin, P2: Injecting with 50% ovaprim + 50% oxytocin, P3: Injecting with 75% ovaprim + 25% oxytocin, P4: Injection with 100% ovaprim, P5: Injecting with 100% oxytocin. The results showed that the best treatment for the effect of ovulation and anchovy egg maturation (Ompok Rhadinurus) was P2: 50% ovaprim + 50% oxytocin which resulted in a latency time of 7 hours 38 minutes, the number of eggs stripping as many as 214 grains / g parent, value ovisomatic index of 16.14%, increase in egg diameter of 0.30 mm, fertilization value of 73.13%, hatching value of 82%, and survival value (SR5 days) of 58.31%. Water quality parameters are: temperature 24-28 ?c, pH: 5-6, DO: 5.2 - 6.3 mg / L. Keywords: Injections, Oxytocin Hormones, Ovaprim Hormones, Stem Fish (Ompok      rhadinurus)

Abstract

ABSTRACTThe research was conducted on May to July 2017. The purpose of this research was to know the best percentage of fermented feather meal in diet and effect on growth of silver pompano (Trachinotus blochii, Lac) fingerling. This study uses a completely randomized design (CRD) with one factor,five treatment and three replications. The research used fish with initial average weight of 0,9 g. Fish were reared in net cage of 1x1x1 m3with the stocking density of 20 fish/net cage. Treatments with fermented feather meal, P0 (0%), P1 (5%), P2 (10%), P3 (15%), P4 (20%). Feed protein content range between 43,94-46,33%. The result show that fermented feather meal give significant effect (P<0,05) on growth, feed efficiency and protein retentions.This result of this study suggest that fermented feather meal can be used as feed material of silver pompano up to 15% from total amount of feed.Keyword:   Bacillus sp., feather meal, fermented,fish feed, silver pompano (Trachinotus blochii, Lac)
