Abstract

Penelitian ini bertujuan untuk mengetahui aktivitas ekstrak kulit buah mentah pisang kepok (Musa paradisiaca x balbisiana) sebagai antibakteri alami dalam menghambat pertumbuhan bakteri Staphylococcus aureus, dan mengetahui konsentrasi ekstrak kulit buah mentah pisang kepok (Musa paradisiaca x balbisiana) yang paling baik dalam menghambat pertumbuhan bakteri Staphylococcus aureus. Eksperimen terdiri dari 5 perlakuan dan 3 kali ulangan yaitu kontrol perlakuan, perlakuan 1 (P1) = Konsentrasi 25% (0,5 mg/2ml aquades), P2= Konsentrasi 50% (1 mg/2 ml aquades), P3= Konsentrasi 75% (1,5 mg/2 ml aquades), P4=100% (2 mg/2 ml aquades). Parameter yang diukur dalam penelitian ini adalah jumlah koloni bakteri Staphylococcus aureus. Data dianalisis dengan menggunakan Standar Plate Count (SPC). Hasil penelitian menunjukkan bahwa ekstrak kulit buah pisang kepok mentah mampu menghambat pertumbuhan bakteri Staphylococcus aureus. Perlakuan dengan konsentrasi 100% merupakan perlakuan paling baik dalam menghambat pertumbuhan bakteri Staphylococcus aureus dengan jumlah koloni terendah yaitu 8,7 x 104 koloni.

Abstract

This research aims to develop student worksheets with team assisted individualization (TAI) cooperative learning models in Pythagoras Theorem materials. This research aims to find out the increased interest in learning and student learning outcomes. The method used in this study uses research and development (R & D) method with ADDIE (Analysis, Design, Development, Implementation, Evaluatio) design. The data collection techniques used in this study are questionnaires, validation sheets and study results tests. Instruments used are device validation sheets, student response questionnaires, student learning interest questionnaires and student learning outcomes. The data analysis technique used is qualitative data consisting of advice and comments from experts and qualitative data judging by the analysis of validity, practicality and effectiveness. The results showed that, learning devices were declared very valid with the average assessment results from experts 4.15, the student response questionnaire reached 73.81% which is intended in the positive category so that the developed LKS is declared practical, the student learning interest questionnaire reached 70.33% that is in the positive category as well as the results of students who reach an average of 81.66% that exist in the complete category.

Abstract Development of Mathematics Learning Tools with Problem Posing Approach to Improve Reasoning Ability and Independence Learning Mathematics. Essay. Mathematics Education Study Program FKIP Muhammadiyah University Kupang. This study aims to develope learning tools with a problem posing approach to improve reasoning skills and independent learning mathematics. The research used is development research with the modified 4-D Models wich include the defining stage, the design stage and the develop. The population in this study were all students of class X SMA Negeri 5 Kupang. The sample in this study were students of class X of SMA Negeri 5 Kupang. Data analysis techniques used in this study to test the validity, the practicality and the effetiveness. The results showed that the learning tools in the form of RPP and LKS that have been analyzed reach very valid categories with an average score of 4,42. While the average percentage of practicality of data reached 81,67% in the good category. The effetiveness of the data obtained by the results of tests of reasoning ability and learning independence questionnaire, obtained from each student each scored 87,5% and 70% namely in the good and sufficient categories. From the results of the analysis, it was concluded that the development of mathematics learning tools with problem posing approach to improve the reasoning ability and independence of learning mathematics was feasible to use.
