Abstract

A study aims to understand the morphological characteristics and growthpattern of Wallago leerii obtained from the Kampar River has been conducted.Morphological characteristics studied were sex ratio, morphometrical and meristicalcharacteristics and also growth pattern (length-weight relationship, condition factorsand otolith) of the fish. During the sampling period, 346 fishes were caught (125males and 221 females). Body length and body weight of the males ranged from330 to1020 mm and 260-10500 gram, while that of the female was 300-920 mmand 140 - 8700 gram respectively. Sex ratio of the fish was 1 : 1.8, it means thatduring the reproductive activities, the number of female may more than the male (1male may fertilize 1.8 females).Equation of body length-weight relationship of the male was W = 384.0L0.068, , while that of the female was W = 374.5 L0,083, and that of all fishes (maleand female) was W = 378.8L0.073. Correlation coefficient (r) was 0.924 for themales and 0.950for females. It means that increasing body length is alwaysfollowed by increasing body weight and growth pattern of the Wallago sp wasallometric. Condition factor of the fish was 0.0517-0.2016, (0.0517-0.2016 formales and 0.0519-0.1447 for females). Based on these data, it can be concluded thatthe fish body was slightly compressed.Keywords : Wallago leerii, sex ratio, growth pattern,Otolith

Abstract

One of the interesting and environmentally friendly microbiology strategies and approaches to control the impact of microplastics is to approach bioremediation technology by harnessing the potential of microbes or indigenous bacteria (local bacteria).  Dumai sea waters currently show a high enough of microplastic pollution which allows the potential of indigenous bacteria to adapt to a plastic environment. The purpose of this study is to isolate and identify indigenous bacteria to degrade plastics from the sea waters of Dumai and to know whether or not there is a difference in the number of bacteria found between stations in this study. This research was conducted in October-December 2020 with experimental methods at the Marine Microbiology Laboratory Faculty of Fisheries and Marine Science Universitas Riau. Based on the results of the study, 12 bacterial isolates were isolated from the research stations.  Isolates of these bacteria have diamaters ranging from 0.2-1.1 cm. Microplastic degradation test results by bacteria found that ISL 10 is an isolate that shows the highest PET degradation activity, which is 17.27% and the diameter of biofilm formation 0.8 cm. Based on biochemical and morphological tests, similar results were obtained that ISL 10 bacteria are a bacterium of the genus Bacillus. The most bacterial colonies were seen in statiun IV (TPI) with an average number of bacteria of 214.9 x 104 CFU/ml.

Abstract

The research was aimed to map the sea surface temperature (SST) distribution in Sibolga waters that based on 20 years satellite image of NOAA/AVHRR. It used survey method for ground check in the field to collect in situ SST and other seawater parameters such as its visibillity, pH, and salinity. It found that the SST changes on each 5 year’s calculations with different pattern of distribution; the figures of SST ranged between 28.5-30  oC, 30.5-31  oC, 27-29  oC, and 27.5-28.5 oC. In addition, the pH of seawater ranged from 6-7 and 27-30 ppt in average. Different pattern of SST distribution might be related to global change on temperature and season over 20 years of study.

This research was conducted from January - March 2020. The aimed of this research was to evaluate the effect of using fermented A. microphylla flour in the diet on feed digestibility, feed efficiency and growth of red tilapia, and the best percentage of A. microphylla flour fermentation in the diet to increase feed efficiency and growth of red tilapia. This study used a one-factor completely randomized design (CRD) with 5 treatments and 3 replications. The treatments in this study were P0 (0% FTA), P1 (25% FTA), P2 (50% FTA), P3 (75% FTA), P4 (100% FTA) in feed. Diet as much as 10% of the weight of the biomass is given three times a day, namely at 07.00, 12.00 and 17.00 WIB. The red tilapia used were 5.50 ± 0.71 cm in size with an average weight of 1.27 ± 0.08g and a stocking density of 25 fish /m3. The results showed that giving azola leaf flour fermented could increase the growth and survival of red tilapia. The use of 25% fermented A. microphylla leaf meal (P1) gave the best results for the feed digestibility value of 75.96%, 76.59% protein digestibility, 62.07% feed efficiency, 85.36% protein retention, specific growth rate 4, 31% and the cost of the test feed is Rp. 8,310.

Tujuan penelitian adalah mendapatkan lama waktu perendaman ikan dalam larutan vaksin HydroVac yang optimal dalam meningkatkan respons imun spesifik ikan patin siam dilihat dari total leukosit, diferensiasi leukosit dan aktivitas fagositosis. Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) satu faktor dengan lima taraf perlakuan, adapun perlakuan pada penelitian adalah: Kn (tanpa perendaman vaksin HydroVac dan tanpa diinfeksi bakteri Aeromonas hydrophila), Kp (tanpa perendaman vaksin HydroVac dan diinfeksi bakteri A. hydrophila), P1 (Perendaman vaksin HydroVac selama 15 menit), P2 (Perendaman selama 30 menit), dan P3 (Perendaman selama 45 menit), serta diujitantang bakteri A. hydrophila). Hasil penelitian menunjukkan bahwa Perendaman dengan vaksin HydroVac dapat meningkatkan respons imun non-spesifik ikan patin siam yang terinfeksi bakteri A.hydrophila. Waktu perendaman selama 30 menit merupakan hasil terbaik untuk meningkatkan respons imunitas ikan patin siam yang terinfeksi bakteri A. hydrophila dilihat dari hasil total leukosit 9,12×104 sel/mm3, kadar leukokrit 1,67%, diferensiasi leukosit (limfosit 82,33%, monosit 8,67% dan neutrofil 9,00%), nilai aktivitas fagositosis 34,67%, dan tingkat perlindungan relatif 83,33%.

Abstract

The slaughterhouse wastewater is rich of oil and fat and it may inhabit by biosurfactant producing bacteria. Isolation of the bacteria is needed in order to find out a biosurfactant producing bacteria that can be used to maintain the oil and fat polluted area through bioremediation process. To isolate and identify the biosurfactant-producing bacteria, a study has been conducted on July to September 2020. The samples were obtained from slaughterhouse wastewater at Cipta Karya street Pekanbaru, Riau Province and samplings were conducted three times. The isolation was conducted by TSB (Tryptic Soy Broth)  and incubated for 24 hours. Then the bacterial samples were planted by TSA (Tryptic Soy Agar)  and isolated for 24 hours. Then, it was identified using biochemical and morphological tests were carried out to find out the types of bacteria. The Emulsification Index was then calculated by using TSB (Tryptic Soy Broth) and kerosene. Results shown that the emulsification index were Flavobacterium 53%, Agrobacterium 53%, Serratia 60%, Salmonella 52. 5%, Salmonella 52.4%, Proteus 65.7%, Clostridium 62% and Aeromonas 59.5%. As Proteus is shown the highest Emulsification Index, it was check using a PCR (Polymerase Chain Reaction) and it is proved that the species is Proteus vulgaris
