Abstract

This study aims to determine the improvement of skills in communicated plant morphological characteristics in Junior High School students in Ambon used the application of the experimental method and the method of gived assignments. Find out the differences in the skills of communicating plant morphological characteristics in Junior High School students used the application of the experimental method and used the assignment method. The research used in this study is a qualitative and quantitative descriptive. The subjects of the study were 7th grade students. The samples taked in this study were divided into 12 classes, namely the experimental class, 4 classes, the assignment class, 4 classes and the control class, 4 classes each received different treatment. Data analysis was carried out experimentally. Results were calculated manually and Anacova statistical analysis. The result is a different test or comparative test with the dependent variable having an interval or ratio data scale, while the independent variables consist of a mixture of categorical data and numerical data.

Abstract

Many abilities that students must have, namely the ability to think critically, think creatively, construct knowledge, solve problems and master learning material well. One of the efforts to improve students' critical thinking and creative thinking skills is to change the old learning model used with the problem-based learning model and inquiry learning model. Students think more critically and think creatively and encourage students to be able to connect between the knowledge they have and its application in their daily lives. This study aims to determine the effect of two learning models, namely problem-based learning and inquiry learning to improve critical thinking skills and creative thinking on ecosystem material in class X SMAN 11, SMAN 13, and Madrasah Aliyah. The type of research is Quasi Experiment using 3 experimental classes using the problem based learning model and 3 experimental classes using the inquiry learning model. The statistical analysis used was multiple linear regression using SPSS 22. The results obtained from multiple linear regression analysis both had significant values <0.05 using both problem based learning and inquiry learning models at SMA N 11, SMA N 13 and Madrasah Aliyah Negeri Ambon. Conclusion. There is an influence of the use of problem-based learning models and inquiry learning models to improve the ability to think in class X SMAN 11, SMAN 13 and Ambon Madrasah Aliyah.

Abstract

Gandaria leaves (Boea macrophylla Griff) have potential as antibacterial. The ability to inhibit bacterial growth is inseparable from the role of active compounds, namely flavonoids, tannins, quinones and triterpenoids. Growth by microbes needs to be controlled, namely by inhibiting microorganisms, one way is by using chemicals, namely antiseptics. This study aims to determine the effectiveness of antiseptics made from gandaria leaves against the growth of S. aureus and E. coli bacteria. The concentrations of the ethanol extract of gandaria leaves used were 5%, 15% and 25% and betadine (+) and aquades (-) were used as controls. Antiseptic effectiveness test against S. aureus and E. coli bacteria using disc diffusion method. The test results showed that the antiseptic based on gandaria leaves had the ability to inhibit the growth of S. aureus with a concentration of 15% at 2.00 mm and 25% at 4.00 mm. Meanwhile, for E. coli bacteria, antiseptic made from gandaria leaves has an inhibition zone at a concentration of 15% at 1.00 mm. In accordance with the criteria for antiseptic power according to Davis Stout, gandaria leaves which are used as basic ingredients for antiseptics are included in the criteria for very weak antiseptic power (≤5). Therefore, the antiseptic based on gandaria leaves in this study was less effective in inhibiting the growth of S. aureus and E. coli bacteria.

Abstract

Processing of black cassava has the possibility of microbial contamination because the fermentation process is carried out in the open, black cassava in the open, at room temperature, allowing microbes such as bacteria to grow. The aim of this research is to determine the length of time for boiling cassava and the presence of bacteria, and to determine the appropriate boiling time that can inhibit the presence of bacteria. From the results of observations of cassava samples containing bacteria before boiling, this shows that fresh cassava used as raw material naturally contains a number of bacteria. Observing the colony characteristics of all bacterial isolates counted and uncounted, it was found that there were similarities and differences in properties, where the results of the analysis showed that the long boiling time treatment had a great influence on the morphology of the bacteria, namely round and wrinkled, with smooth and grooved edges, raised elevations, flat and thick. The color of the bacteria on black cassava is the same, namely white, with treatment times of 10, 20, 30 minutes. The boiling time treatment has a very significant effect on the shape, edges and elevation in the presence of bacteria. The presence of bacteria in black cassava before boiling shows that it naturally contains a number of bacteria, with long boiling treatment the number of bacteria increases.
