Abstract

ABSTRAK   Penelitian survei yang menggunakan angket ini diberikan pada 27 guru Biologi di 12 SMP Negeri dan Swasta di Tondano Kabupaten Minahasa. Penelitian ini bertujuan mendeskripsikan respon guru biologi terhadap strategi yang mampu memberdayakan kemampuan berpikir kritis dan hasil belajar siswa. Berdasarkan jawaban responden, yang mengemukakan sangat penting melibatkan kemampuan berpikir kritis dalam pembelajaran (11,11%), penting (51,85%), dan jawaban kurang penting (0%), serta sisanya (37,04%) tidak memberikan jawaban. Responden yang menjawab telah mengembangkan strategi berpikir kritis dalam pembelajaran (62,96%), yang belum (3,70%), sedangkan (33,33%) tidak menjawab. Dalam pemberdayaan kemampuan berpikir kritis siswa, responden menjawab: sangat penting ( 14,81%), penting (48,15%), dan kurang penting (0%), serta tidak dijawab (37,04%). Lebih lanjut, yang menjawab benar bagaimana langkah-langkah memberdayakan kemampuan berpikir kritis siswa 48,15%, sedangkan sisanya (51,85%) tidak menjawab. Hal ini mengindikasikan sangat perlu lebih dikembangkan suatu strategi yang mampu memberdayakan kemampuan berpikir kritis, meskipun terdapat (59,26%) responden menjawab adanya kendala dalam memberdayakannya. Hal ini terkait pula dengan penilaian hasil belajar terkait cakupan tiap domain kognitif, afektif dan psikomotorik, di mana (7,41%) responden menjawab benar cakupan tiap domain, dan (44,44%) menjawab tidak benar, sedangkan (48,15%) tidak menjawab.   Kata Kunci : Berpikir Kritis, Hasil Belajar.

Abstract

Leaf leilem (Clerodendrum minahassae Teism. & Binn.) commonly used by the Minahasa as food and traditional medicine for treating intestinal worms, abdominal pain, and pain in the chest. Gram-positive bacteria Staphylococcus aureus ATCC 25923 strain is a type of bacteria that is found in humans and can be the cause of the emergence of the disease. This research aims to know the types of solvents are most effective and how the antibacterial activity of extracts of leaves of leilem on the growth of the bacteria Staphylococcus aureus strains ATCC 25923. The solvent used is ethanol is polar, ethyl acetate which is semi polar, and n-heksan which is non polar. Preliminary research has been conducted on konsenterasi extract with 100 ppm 200 ppm 400 ppm and 800 ppm, the antibacterial activity of the most optimal at 800 ppm so the data will be used for the analysis in this study was konsenterasi 800 ppm. Deuteronomy was done by as much as 3 times. Positive control using antibiotics clindamicyn 400 ppm and negative controls using aquades and 10% DMSO. Isolation of bacteria using scratch in zig-zag and to test the antibacterial activity of using diffusion well in order. Results of the study showed that the percentage yield of solvent is ethanol that is 1,2329% in maceration 1:4. Drag the diameter of most bacteria are grown on ethyl acetate extract polar spring with a grade average of 12.6 mm. Based on the analysis of OneWay ANOVA showed different results for real then followed by Tukey test, to see that these three types of different extract significantly in inhibiting the growth of gram positive bacteria Staphylococcus aureus strains ATCC 25923. In conclusion, namely the first ethanol is a solvent that is most effective in dissolving the leaves leilem, both of the antibacterial activity in sequence from the most minor to the most massive is the n-heksan (non-polar), ethanol (polar), and ethyl acetate (semi polar). The third conclusion in the optimum konsenterasi 800 ppm, extract n-heksan n-heksan (non-polar), ethanol (polar), and ethyl acetate (semi polar) showed antibacterial activity significantly different.
