Abstract

Model pembelajaran Problem Based Learning (PBL) merupakan model pembelajaran yang dapat memberdayakan keterampilan berpikir kritis . Media flipbook digunakan agar siswa lebih termotivasi dalam belajar dan tidak cenderung membosankan. Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan berpikir kritis siswa melalui penerapan model Problem  Based Learning (PBL) berbasis media flipbook. Penelitian ini menggunakan jenis penelitian kuantitatif dengan metode Quasi Eksperimental dan desain kelompok kontrol pretest-posttest. Sampel penelitian ini adalah siswa kelas X IPA 6 terdiri dari 24 siswa sebagai kelas kontrol dan kelas X IPA 7 25 siswa sebagai kelas eksperimen.Instrumen yang digunakan adalah 25 butir soal pilihan ganda dengan indikator mencakup menganalisis (C4), megevaluasi (C5) dan mencipta (C6). Analisis data dilakukan dengan uji t yang dilanjutkan uji N-gain, Hasil penelitian menunjukkan rata-rata nilai posttest kelas eksperimen sebesar 83,04 dan kontrol sebesar 72,83, terdapat perbedaan peningkatan kemampuan berpikir kritis antara kelas eksperimen dan kelas kontrol. Dengan menggunakan uji N-Gain diperoleh hasil sebesar 73% dengan kategori cukup efektif, sehingga dapat disimpulkan terdapat peningkatan kemampuan berpikir kritis dalam kategori cukup efektif pada pembelajaran dengan menggunakan model Problem Based Learning (PBL)  berbasis media Flipbook pada materi Pencemaran Lingkungan. Kata Kunci: Flipbook, Keterampilan Berpikir Kritis, Problem Based Learning.

Abstract

This study aims to identify the forms of starch in edible plants. This research involved several edible plants such as sago, yam and taro. This type of research uses descriptive quantitative methods by conducting experiments on each sample used. The data collection technique was carried out by describing the results of the starch form from each sample that had been obtained. The results obtained from this study showed that the Sago preparations viewed under a microscope had an oval starch shape and spread throughout the preparation so that it was classified as an eccentric starch type that could be seen at 10X magnification, while Jicama starch preparations had a round starch shape and chains in some parts. The plane of the preparation and entered in the concentric type, but the shape of starch in Jicama can be seen under a microscope at 100X magnification, the Taro preparation has a round and lumpy shape but the starch accumulates in several areas of the preparation and enters the concentric type seen at 40X magnification. So it can be concluded that the forms of starch in edible plants are very diverse, both in round to oval shapes, with smooth and rough starch structures, namely in the form of lumps.Keywords: Edible Plants, Starch Form
