Abstract

ABSTRACT   Secondary metabolites are a molecule or product of metabolites produced by the metabolic processes of microorganisms where the metabolite products are not a basic necessity of living microorganisms and for growth, but secondary metabolites can also function as emergency nutrients to survive. Marine bacteria including heterotrophic bacteria are capable of producing secondary metabolites. This study aims to determine the ability of secondary metabolite production of heterotrophic bacteria to inhibit the activity of pathogenic bacteria (Vibrio alginolyticus, Aeromonas hydrophila and Pseudomonas sp). In this study using the experimental method. 10 Heterotrophic bacterial isolates obtained from a collection of marine microbiology laboratories were cultured on NB media ± 3 days until the media was cloudy and harvest during stationary times, then extracted secondary metabolites from the media and shells using Etyl Acetate. The secondary metabolite extract will be tested against pathogenic bacteria (Vibrio alginolyticus, Aeromonas hydrophila and Pseudomonas sp). Based on the results of the antagonism test conducted, 10 heterotrophic bacterial isolates were able to inhibit the growth of all three pathogenic bacteria. Based on the antagonism test, the highest inhibitory value was Bacillus cereusspecies (KM489154.1) with an average diameter of about 10.08 mm, while the inhibition power which was classified as the lowest or categorized as moderate was found in the Bacillus safensis species (KY495152.1 ) with an average diameter of around 7.33 mm. The ability to inhibit pathogenic bacteria is suspected because this heterotrophic bacterial species produces antibiotic compounds. Keyword :Secondary metabolites,  Heterotrophic Bacteria, Antagonism test

Abstract

ABSTRACT This research was conducted on 19 June - 03 July 2018 in Nagari Koto Malintang Kecamatan Tanjung Raya Kabupaten Agam Provinsi Sumatera Barat. The purpose of this study was to determine the reason for the establishment of a working relationship, to know the pattern of work relationships and to know the advantages and disadvantages of the relationship between the tauke and KJA fish farmers. The research method used is the Phenomenological Qualitative Method by conducting direct observation and interviewing informants who are guided by the questionnaire. The informant determination technique used is Purposive Sampling which is considered by researchers that the informants have in-depth information and can be trusted to be a solid source of data. The number of informants was 7 people consisting of 2 tauke and 5 fish cultivators.               Research results show that the reasons for the establishment of a working relationship are: first, economic factors in meeting the needs of life, secondly, the employment factor and the three factors of kinship. While the pattern of employment relationships are patterns of economic relations, patterns of social relations and patterns of personal relationships. The advantages and disadvantages between tauke and fish cultivator are collateral for borrowing capital for daily needs borrowed by the tauke, but the catch must be sold to the tauke not be sold to other parties. Keywords: Pattern of Employment Relations, Boss, Cultivator, Floating Net Cage

Abstract

ABSTRACT This study aimed to determine the effect of different addition of fish(Clarias gariepinus, Pangasius djambal, and Paraplotosus albilabris) bone flour on the cookies quality and obtain the best formulation of cookies with addition differentfish bone flour. The experimental method with a non-factorial Completely Randomized Design was used in this research with 4 levels of treatment: cookies without addition of fish bone flour (CT0), cookies with addition 8gr of Clarias gariepinus bone flour (CT1), cookies with addition 8gr of Pangasius djambal bone flour (CT2), cookies with addition 8 gr of Paraplotosus albilabris bone flour (CT3). The parameters measured in this study were organoleptic test (appearance, odor, taste, texture),proximate analysis (water, protein, fat, ash and calcium content). The results showed that the addition 8 gr of Pangasius djambal bone flourwas the best treatment, whereas the appearance was brown, attractive, whole and neat, odor was distinctive smelling cookies, fragrant and slightly smelling fish, taste was good, savory and a little taste of fish, texture was dry, solid, compact and crunchy. Based on the best proximate analysis that the addiiton 8 gr of Paraplotosus albilabrisbone flour was the best treatment (CT3), where as the value of water, protein, fat, ash, carbohydrate and calcium content was 5.71%, 25.5%, 1.7%, 2.38%, 66.66%, 1.28%, respectively.Keywords: Clarias gariepinus, Cookies, Fish Bone Flour,Pangasius djambal, Paraplotosusalbilabris

Abstract

AstractOne of the biota that lives in mangrove ecosystems is the gastropod telescopium telescopium. Telescopium telescopium has more active behavior at spring tide (high tide and low tide) than low tide (low tide and high low tide). The weight of the gonad will reach a maximum of a moment when the mangrove snail will spawn, then the weight of the gonad will decrease rapidly as long as the spawning is in progress until complete. This research was carried out in June-July 2018, sampling in the mangrove ecosystem of Ketapang Beach waters, Sungai Cingam Village, Rupat District, Bengkalis Regency, Riau Province. The samples were analyzed at the Marine Biology Laboratory of the Faculty of Fisheries and Marine Sciences, Riau University. This study aims to determine the population structure of gonad maturity index and habitat conditions of T. telescopium gastropods in Ketapang Beach waters, Sungai Cingam Village, Rupat District. The method used in this research is survey method. Measurement of water quality parameters is carried out in situ, namely temperature, and determination of sampling locations by purposive sampling, salinity and pH, type of substrate in sandy mud dominance. Water quality parameters are still supportive for the life of mangrove snails. Average density of Tcopcopium T in the mangrove forest of Sungai Cingam Village is low. There were no differences in density between the research stations but there were differences in density between the study zones. The average distribution pattern of T. telescopium is clustered. The size of T. telescopium found ranged from 38-87 mm. The main habitat of T. telescopium is in zone 2 (lowere zone).Keywords: Population structure, Telescopium telescopium, Rupat Island.
