Abstract

Bioinformatics has developed into an application tool for basic and applied research in the biomedical and biotechnology field. Polymerase Chain Reaction (PCR) is a common technique in the molecular area that has always involved bioinformatics science. PCR cloning techniques such as TA cloning and PCR-mediated cloning exhibit complex processes with low success rates. One easy, effective, and practical solution is to use a mega-primer with the Overlap Extension PCR Cloning (OEPC) technique. The success of PCR cloning using the mega-primer design in the OEPC technique is strongly influenced by the characteristics of the mega-primer used. Knowledge of mega-primer characteristics is one of the important factors in the success of PCR cloning. The design process for the mega-primer str promoter was characterized based on the principle of a genetic algorithm using the web-based bioinformatics tools such as ClustalW, NetPrimer, and BLAST. The success of the mega-primer construction in producing recombinant pSB1C3 vector has been confirmed by the sequencing method and the function of the reporting protein (AmilCP). DNA analysis shows a 100 % homologous sequence on the str promoter, while  E. coli colonies successfully express the purplish-blue color. Mega-primer characters can save costs and time of the research by maintaining the primer parameters that provide optimal values and increase the success value of PCR cloning via bioinformatics software. Hence, implications on biological problems, especially using DNA and amino acid sequences, could solve rapidly.

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 pattern of antibiotic consumption by the community which is carried out independently without medical guidance causes antibiotic pollution has reached sea waters, one of its impacts on the nature of bacterial resistance. This study aims to look at the pattern of antibiotic sensitivity to E coli that isolated from Dumai sea waters. E coli isolates that grown on MHA media were tested based on the Kirby Bauer disk diffusion method. Seventeen isolates were identified, among which a high rate of resistance to penicillin, isoniazid and streptomycin (17), a high rate of resistance to chloramphenicol (5), intermediate susceptibility to chloramphenicol (11) and only 1 sensitive to chloramphenicol. The multiple antibiotic resistance (MAR) index of E coli isolates was 0.82. These show that antibiotics like penicillin, isoniazid, streptomycin and chloramphenicol were not suitable antibiotic for E coli infection treatment. The community is expected to be more disciplined in using antibiotics and to be careful in using the Dumai sea for fishery activities

Abstract

Teluk Rhu Village is a village that has potential in terms of fisheries and marine tourism. Some of the people in this village are fishermen, and the rest are fish farmers. The minimum knowledge and competence have fishermen in Teluk Rhu Village cause the welfare to be relatively low. To improve the fishermen's income needed knowledge improvement through food diversification technology based on fishery products. There are four methods used in this program, such as observation, material delivery, product manufacturing practices, and program evaluation. Twenty fishermen were participants and were involved very enthusiastically and actively in this program. There were two materials presented to increase fishermen's knowledge, including digital literacy and food innovation products. Lastly, all participants were trained to make several processed food products such as fish balls, nuggets, and fish sticks. The questionnaire data show that the community service program had several benefits for most participants. Thus, it's hoped that the new knowledge can make them more enthusiastic and motivated to begin a new businesses to increase family income.

Abstract

The problems that are often experienced when cultivating goldfish are diseases caused by pathogens that attack cultivated fish. The cause of disease in fish is caused by interactions between fish, pathogens and their habitat environment that can cause death in fish. The solution to this problem is to provide a phytoimmunostimulant derived from mango leaves (Mangifera indica). The purpose of this study was to determine the effect of mango leaves on the hematology and physiology of common carp. This research was conducted in January-April 2022. The method used in this research is an experimental method by comparing data. Parameters observed were total erythrocytes, hemoglobin, hematocrit, blood glucose, absolute body weight growth, survival rate, and water quality. Based on the research that has been done, it can be concluded that the addition of 1.5% mango leaf powder into fish feed as a phytoimmunostimulant affects the hematological and physiological effects of common carp. Common carp treated with phytoimmunostimulants in fresh water had higher mean values ​​(total erythrocytes 1.75x106 cells/mm3, hematocrit 33.66%, and hemoglobin 8.13 g/dL) compared to data in brackish water (total erythrocytes 1.54x106 cells/mm3, hematocrit 30.66%, and hemoglobin 7.76 g/dL).
