Abstract

Anti-Biotic resistance is a health problem globally. It is able to overcome with a new anti-microbial compound that can be produced from Andalas endophytic bacteria. This compound can be obtained through the fermentation process. In order to separate this active-compound, it is needed to use the extraction method. In this method, the solvent is functioned as the extractor. One of the solvent which is commonly used is ethanol. This research is aimed to know the effect of ethanol concentration toward antibacterial activity from extracted bacterial fermentation products of Andalas endophytic bacteria isolate JDT 1B. The fermented products are extracted by using the maceration method. The concentrations are 100%, 80%, 70%. A test of anti-microbial activity is used disk diffusion method. The extracted concentrations tested for each solvent are 50%, 25%, 12,5%, and 6.25%. Anti-bacterial activity is analyzed by using factorial design. The factorial result showed there is no significant contrast between ethanol concentration mentioned toward anti-bacterial activity from extracted bacterial fermentation products of Andalas endophytic bacteria Isolate JDT 1B. The concentration of extracted fermentation product using 70% ethanol has the same inhibition zone as control is 6,25%.

Abstract

Science literacy and reading literacy are two key competencies that not only support academic success but also prepare children to face global challenges in the 21st century. Science literacy includes the ability to understand scientific concepts, think critically, and apply that knowledge in everyday life. Meanwhile, reading literacy involves the ability to understand, analyze, and use information from written texts. Science literacy and reading literacy of elementary school children in Binjai Village are still low and need holistic education with interdisciplinary learning programs. This community service program aims to improve science literacy and reading literacy of elementary school children in Binjai Village through interdisciplinary learning. The implementation method in this community service activity is in accordance with the partner's problem, through training in interdisciplinary learning that includes aspects of science literacy and reading literacy in English and Arabic adapted from quantitative research methods with a one-class pretest-posttest design. This service was carried out in Binjai Village, Tebing Syahbandar District, Serdang Bedagai Regency. There were 30 elementary school children who participated in this activity. The results of this activity show an increase in science literacy and reading literacy of elementary school children in Binjai village.
