Abstract

Kaempferia galanga L. or known as Kencur is an herbal plant that is widely used by people with various benefits such as influenza in infants, headaches, sprains, relieving fatigue, inflammation of the stomach, coughing, improving menstruation, inflammation of children's ears, dirty blood, eyes aches, diarrhea, and colds. However, studies that have used Kencur as an antibacterial against Staphylococcus aureus have never been done. Therefore, scientific research is needed to determine the ability of Kencur extract as an antibacterial that inhibits the growth of Staphylococcus aureus. 3 extraction methods were used, with the aim of determining the right method for obtaining Kencur bioactive compounds as antibacterial. The three extraction methods used were the press method, the infusion method, and the maceration method using methanol as a solvent. Each extract obtained from various extraction methods will be tested for antibacterial by observing the growth of Staphylococcus aureus. It was found that with the press method there were no clear zones or growth inhibition zones of Staphylococcus aureus. Using the extract from the infusion method, the same thing is obtained, namely there is no clear zone or growth inhibition zone of Staphylococcus aureus. However, it is different when given an extract from the maceration method using methanol solvent, a 17 mm clear zone is formed but there is no inhibition zone. This can indicate that, methanol extract from Kencur can inhibit the growth of Staphylococcus aureus (17 mm).

Abstract

Verbal scientific communication skills observed in this study include: asking questions, answering questions, contributing ideas / opinions, responding to other students' opinions, and conveying the results of the discussion. Based on the results of the study concluded that the oral communication skills of Al-Azhar Kayangan high school students through learning the integration model of local wisdom are still in the low category. A skill cannot be taught in a short time so it needs to be practiced repeatedly so that students become more skilled. Further research is needed to be related to non-verbal communication skills at the same location and students so that observation of students' communication skills is more comprehensive.

Abstract

Biology is a basic science for studying living things. Basically, some biological content that is contemporary in the learning process is not only in the form of transfer of information and facts from the teacher to students through what they see and what they hear through specific information processing, but requires literal understanding of concepts. Provision of material biological concepts become biased and inherent in one's understanding and cause cognitive conflict that leads to misconceptions. The purpose of this study is to describe the results of the analysis of students' mastery of concepts in solving problems that are considered correct but theoretically wrong. The analysis used in this study was by identifying students' level of understanding in a material and concept. Conclusions from the study that the level of student misconception through its CRI analysis> 2.5 of 30 students, 97% experienced misconception. For this reason, it is necessary to study biological material and be revised by the teacher and students by studying the material and concepts that are correct or bringing in experts in the field of biology.
