Abstract

This research aimed to determine the effect of PQ4R learning strategy using comic media on students interest and cognitive ability toward the nervous system concept. The method was a quasi-experimental desain with randomized control group pretest posttest. PQ4R learning strategy using comic media was as independent variables, and cognitive abilities was as dependent variables. Population in this research were all of students classXIIPA1Ciomas High School, academic year 2012-2013. Overall subject of population was used as the sample of research.Sample class XI IPA 1 as an experiment class and XI IPA 2 as a control class. Sampling technique used random sampling. Instrument used were multiple choice test for determining students cognitive ability, observation sheets and documentation. All the instrument, were analyzed by t testfor hypothesis.The resultof hypothesis showed the influence of PQ4R learning strategyusingcomic media on students interest, cognitive ability

Abstract

AbstractGeneral microbiology course provide comprehensive introduction to fundamental aspects of microbial world so that student gain an insight into theory, practices and able to demonstrate in the term of knowledge skills and values to overcome problem in the environment. Therefore student should have psychomotor skill as well as cognitive. The present study aimed to identify and describe the psychomotor skills of Pre Service Biology Teacher through microorganism cultivation experiment in the laboratoratory. Data were collected from 94 Pre Service Biology Teacher who enrolled General microbiology course in the even semester of academic year 2016-2017 using psychomotor skill observation sheet. Six dimensions observed: perception, set, guided response, mechanism, adaptation and originalation. Findings indicated that student psychomotor skills was categorized as good with the value of 81,2%.

Abstract

Pollutants can cause pollution and poisoning of biotic components in a natural ecosystem in dangerous compounds such as hydrocarbons, mercury, ammonium nitrogen, and difficult-to-degrade plastics. Therefore, bioremediation is used to manage and control pollutants through bacteria. This article provides an overview of the latest information regarding bacteria as bioremediation agents and the technology's mechanisms. The method used is qualitative data breakdown by observing and drawing conclusions in the journal to examine the role of bacteria as bioremediation agents for harmful pollutants. Based on the study, bacteria have a unique metabolism to degrade inorganic and organic pollutants such as hydrocarbons (including petroleum), diesel oil, ammonia nitrogen, cellulose, starch, fat, styrofoam, chromium, and heavy metals. Furthermore, the overall environmental conditions can also help the organisms involved to accelerate the bioremediation process.
