Abstract

Bacteria has an important role in decomposition and productivity activities in mangrove ecosystem. The study about identification of decomposing mangrove litter bacteria in Dumai has never been done. The aim of this study is to determine Total Plate Count and identify the dominant bacterial species from decomposing Rizhopora sp, Xylocarpus sp, dan Avicennia sp litter in Dumai. The method used in this research was survey method, bacterial isolation was done by pour plate method which is used in total calculation of bacteria was Total Plate Count (TPC), and identify the dominant bacterial in mangrove litter. The total bacteria which gained on Avicennia sp leaf litter are 0,64 x 105 Cfu/ml. On the other hand, the total bacteria from Rhizopora sp leaf litter has a lower number of colonies that is 0,55 x 105± 0,01 Cfu/ml. The bacterial identification test was carried out by gram staining method and morphological observation by microscopy. The dominant bacterial species in three mangrove species (Rizhopora sp, Xylocarpus sp, dan Avicennia sp) are Micrococcus sp dan Aerococcus sp. Keywords : Total Plate Count, Micrococcus sp, Aerococcus sp, Organic Matterial

Abstract

The handling of catches on ships in connection with capture fisheries in particular has the aim of preventing or reducing spoilage of fish and the possibility of a decline in the quality of the catch resulting in loss of selling prices. The main causes of the decline in the quality of the catch on the ship there are 5 factors namely how to handle, human resources, facilities, equipment, fishing units. Handling of catches on the ship with the puse seine Tangkap tool in PPN Sibolga based on calculations regarding the imbalance and suitability of the 5 factors handling on the purse seine ship namely handling methods, human resources, facilities, equipment and capture units found that the average value of conformity is by 78%, with the quality management policy in KEPMEN-52A/2013 which is an average of 78%, handling factors that can be fairly good.

Abstract

Cathepsin was proteolytic enzyme which is found animal tissues included fish. Cathepsin found in fish muscle tissue, cathepsin and other hydrolyzing enzymes were place in subcellular organelles and divided into two places,  that was in muscle fibers and extracellular matrix. The aimed of this study was to the characterization of cathepsin enzyme especially catfish. So that in enviromental condition that can increased the activity of cathepsin enzyme an approtiate handling process can be carried out. The method of analyze enzyme activity, while the measurement of protein concentration refered to Bradford (1976). The treatments in this study was determination temperature (30oC, 40oC, 50oC, dan 60oC) and substrate (1.5% 2%, 2.5%). The result showed of enzyme activity with detrmination temperature very influential and fluctuating, the optimum temperature was 30oC where the activity reaches 0.38 U/ml. The best activity treatment of substrate was 1.5% where the activity reaches 0.42 U/ml.

Abstract

Fish sauce is a fermented product in the form of a dark brown liquid, it tastes relatively salty or sweet and smells good. The process of making fish sauce requires a long time. The proteolytic enzyme addition before fermentation can shorten the time in making fish sauce. The purpose of this study was to determine the fermentation process fish sauce from chicken feather by using enzymatic hydrolysis with pineapple juice, the effect of adding pineapple juice and fermentation time and to determine the results of the enzymatic organoleptic test and the most preferred by panelists. The method used in this research is an experimental quantitative method. Data analysis was done by using a completely randomized design (CRD). From the results of this study, the fermentation process of  chicken feather fish sauce by adding different pineapple extract (25%, 50% and 75%) from the weight of fish meat with fermentation time of 3 days, 6 days, 9 days, 12 days and 15. day. The analysis of the chicken feather fish sauce was done by using sensory (smell, taste, color and thickness). The best research results was obtained by increasing the concentration of pineapple extract by 25% at the fermentation time of 9 days with the criteria of unique, sweet flavor and brownish fish sauce that panelists like from the addition of a concentration of 25% pineapple extract at the fermentation time of 9 days in the fish sauce. This shows that the addition of pineapple juice extract can accelerate the fermentation process besides affecting the preferred hedonic value. Keywords: Bromelain enzyme, Fermentation, Bulu ayam fish, Fishsauce

Abstract

This study aims to determine the effect of administration of activated charcoal, zeolite, and manganese greensand on survival Oreochromis niloticus. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 repetitions. The treatments are P1 = without administration (control), P2 = administration of activated charcoal 10 gr/l P3 = administration of Zeolite 10 gr/l and P4 = administration of manganese 10 gr/l. The parameter observed in this study was survival Oreochromis niloticus. The results showed that administration of activated charcoal, zeolites, and manganese greensand significantly affected the survival of Oreochromis niloticus. The best value is obtained at treatment P1; P2; and P3, each with the best average survival value of 96%; 91%; and 91%. The lowest cost incurred is the treatment P1 Rp. 66.200, - with SR 96% transportation.

Abstract

Macrozoobenthos are organism that can be used as bioindicators of water quality because of their population changes influenced by environmental factors. The research was conducted in the coastal flow area of Karang Anyar Pantai Tarakan City, because this area is suspected to be a source of pollutants with varying environment conditions. The purpose of research is to know the physical chemistry of the water-chemical physics area from Karang Anyar Pantai with the index diversity (H ) of macrozoobenthos as bioindicators. The Sampling methods was purposive sampling. Calculation of diversity index (H'), similarity (E), and Dominancy (D) use the Shannon-Wienner index. The variables measured include physics (temperature, brightness, current velocity, and turbidity) and chemistry (pH and DO). The results showed an abundance of macrozoobenthos ranging from 2045-4129 ind/m. The value of the Diversity index (H) of macrozoobenthos ranges from 0.19 to 0.24.Keywords: DAS Karang Anyar Pantai, diversity, Macrozoobentos

Abstract

Milkfish is  euryhaline fish that can live in wide range salinity, so it will affect with osmoregulation processes. This research aimed to examine the osmotic response of milkfish fingerling during cultivation processes in brackishwater ponds at Wonorejo Village district of Kendal. The  research was conducted on July-October  2016. The cultivation process of milkfish fingerling has been cultured for 60 days in 2000 m2 brackishwater pond. The initial density of milkfish larvae was 100 individuals /m2 with a lenght size of 10 mm on average and 15 days old. Samples of milkfish fingerling were taken on the 20th, 40th and 60th days, the number of samples was 3 individuals every size. The measurement result of blood osmolarity was 460, 05 to 490.10 mOsm / l H2O higher than media osmolarity 38,98 – 194,5 mOsm/l H2O. The osmotic response of  milkfish fingerling were hyperosmotic to the hypotonic environment and osmoregulator fish.

Abstract

This study aims to determine the rate of growth, survival, and feed conversion ratio in feed of Cyprinus carpio with Hylocereus polyhizus. This study used a Completely Randomized Design (CRD) consisting of 4 treatments and 4 replications. The treatments in this study include 0% (P0), 5% (P1), 10% (P2), and 15% (P3). The method of feeding uses 5% feeding rate with a frequency of three times a day (morning, afternoon, evening). The research parameters observed included survival, specific growth rate, feed conversion ratio and water quality. Quantitative research results showed the best survival at P3 of 92.5%, the best specific growth rate at P3 treatment was 0.04 g / day, the best feed conversion ratio at P3 was 1.06, while the results of qualitative research on water quality showed temperature, pH, Dissolved Oxygen is in optimal condition according to the water quality of koi fish. The conclusion of the 15% treatment study (P3) is the best dose of Hylocereus polyhizus substitution of Cyprinus carpio with increased survival and specific growth rate, and decreases the rate of feed conversion ratio.  Keywords: Cyprinus carpio, Growth, Hylocereus polyhizus, Production, Survival Rate.
