Abstract

Abstrak. Penelitian ini bertujuan untuk mengetahui jenis-jenis keterampilan berpikir kritis yang dikembangan melalui instrumen penilaian pada Program studi Magister Pendidikan IPA Universitas Mataram. Instrumen penilaian yang dikembangkan oleh dosen- dosen pengampu matakuliah Program Studi Magister Pendidikan IPA (PSMIPA) Program Pascasarjana Universitas Mataram dicocokkan dengan indikator keterampilan berpikir kritis yang dikembangkan oleh Ennis (1985). Respon dosen- dosen pengampu matakuliah PSMIPA Program Pascasarjana Universitas Mataram terhadap hasil analisis instrumen penilaian dan indikator berpikir kritis dijaring melalui FGD. Dalam kegiatan FGD juga diidentifikasi pola dan strategi pembelajaran yang dapat mengembangkan keterampilan berpikir kritis di PSMPIPA Unram. Hasil penelitian menunjukkan sub indikator keenam keterampilan berpikir kritis yaitu keterampilan membuat deduksi dan mempertimbangkan hasil deduksi sebanyak 26,7% dan sub indikator kedua yaitu menganalisis argumen sebanyak 32,2% merupakan sub indikator paling banyak digunakan dalam instrumen penilaian PSMIPA Program Pascasarjana Universitas Mataram. Dari hasil FGD disimpulkan bahwa instrumen penilaian yang dikembangkan harus lebih mendorong mahasiswa untuk berpikir kritis dari katagori yang sederhana menuju ke kompleks dan instrumen dapat berupa penugasan atau ujian yang sifatnya open books atau take home. Kata kunci: Keterampilan berpikir kritis, instrumen penilaian Abstract: The purpose of this study is to determine the kinds of critical thinking skills which are developed through assessment instruments in Science Education Program, Graduate School University of Mataram. Assessment instruments were developed by lecturers of Science Education Program, Graduate School University of Mataram that were matched with indicators of critical thinking skills Ennis (1985). Lecturer responses on the study results were captured through Focus Group Discussion (FGD). FGD also identified the patterns and learning strategies that can develop critical thinking skills in Science Education Program, Graduate School University of Mataram. The results showed that the sub-indicators of made deduction and deduction considered (26.7%) and sub-indicator of analyzed arguments (32.2%) were the most widely used in the assessment instruments of Science Education Program, Graduate School University of Mataram. FGD results concluded that the assessment should be developed to encourage students to think critically from the simple category to complex category, and the instrument can be an assignment or examination which is conducted an open books or take home.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh Media Animasi Submikroskopik (MAS) terhadap kemampuan representasi siswa pada setiap sub materi pokok larutan penyangga. Penelitian ini menggunakan nonequivalent pretest-posttest control group design. Hasil penelitian menunjukkan bahwa peningkatan (N-gain) kemampuan representasi siswa kelas eksperimen lebih tinggi (p=0,002) dibandingkan kelas kontrol. Selain itu, rata-rata N-gain kemampuan representasi siswa kelas eksperimen lebih tinggi daripada kelas kontrol pada setiap sub materi pokok. Konsep komponen larutan penyangga mengalami peningkatan tertinggi di kelas eksperimen (rata-rata N-gain = 81,21%). Konsep pH larutan penyangga mengalami peningkatan tertinggi di kelas kontrol (rata-rata N-gain = 76,42%). MAS memuat konsep larutan penyangga pada level submikroskopik dengan jelas sehingga dapat membantu siswa memahami konsep-konsep pada level makroskopik dan simbolik. Berdasarkan hasil penelitian ini disimpulkan bahwa MAS dapat meningkatkan kemampuan representasi siswa pada setiap sub materi pokok.

Abstract

Latar Belakang: Efek ekstrak buncis (Phaseolus vulgaris) terhadap ambilan 14C-D-glukosa otot soleus telah diuji pada tikus diabetes induksi aloksan. Metode: Metode perunutan radioisotop dengan 14C-D-glukosa digunakan untuk mengukur ambilan glukosa otot soleus, sedangkan metode enzimatik glukosa oksidase-peroksidase digunakan untuk menentukan kadar glukosa darah. Pengukuran dilakukan pada jam ke 1, 3 dan 5 setelah pemberian secara oral ekstrak buncis dengan dosis 300 mg/kg bb. Hasil: Hasil penelitian menunjukkan bahwa ambilan 14C-D-glukosa otot terbesar (p<0,001) terjadi pada jam kelima setelah pemberian ekstrak. Efek ekstrak buncis terhadap ambilan 14C-D-glukosa otot dua kali lebih kuat dibanding efek metformin yang digunakan sebagai pembanding standar obat hipoglikemik oral. Kesimpulan: Efek ekstrak buncis terhadap penurunan kadar glukosa darah maupun respon ambilan 14C-D-glukosa otot yang dihasilkan lebih tinggi dibanding efek metformin.

Abstract

Fitosterol merupakan sterol nabati, termasuk dalam senyawa metabolit sekunder dan memiliki manfaat yang luas dalam bidang kesehatan. Sumber bahan alam yang mengandung senyawa fitosterol telah banyak digunakan sebagai bahan obat, salah satunya yaitu buncis (Phaseolus vulgaris L.). Penelitian ini merupakan penelitian eksplorasi, bertujuan untuk menganalisis kandungan senyawa fitosterol dalam ekstrak air, ekstrak etanol, dan hasil partisi dari ekstrak air buah buncis menggunakan teknik KLT dan KG-SM. Hasil uji fitokimia menunjukkan bahwa dari 13 ekstrak hasil partisi dengan pelarut n-heksan, DCM, etil asetat, dan metanol, hanya 5 ekstrak yang menunjukkan positif steroid, diantaranya ekstrak air, residu heksan, residu DCM, ekstrak metanol, dan residu metanol. Ekstrak etanol juga menunjukkan positif steroid. Hasil uji KLT pada residu heksan hasil partisi dari ekstrak air diduga merupakan senyawa stigmasterol karena memiliki harga Rf = 0,9 sama dengan harga Rf senyawa standar stigmasterol, sedangkan pada ekstrak etanol, senyawa fitosterol yang terdeteksi yaitu γ-sitosterol 6,01% dan stigmasterol 2,48%.

Abstract

This research employs Ex Facto approach to analyse the relation between prospective teachers’ critical thinking tendency (CTT) and their critical thinking skills (CTS) towards their learning outcome. The subject of this research the fifth semester students of Chemistry Education, Faculty of Teaching, Universitas Mataram academic year of 2017/2018. The research focuses on the teaching of Chemical Physics III subject to 40 people who are chosen under purposive sampling method. The variable of attribute is the use of project-based learning and CTT while the dependent variable is the CTS and students’ learning outcome. The data of CTT were obtained through questionnaires focusing on the matter while the students’ CTS and learning outcome were measured using essay tests. The analysis of the data utilizes Pearson correlation test. The result of the test showed significant relevance between CTT and CTS (rcount ; 0.341 > rtable ;0.312). Meanwhile, the total of CTT and learning outcome do not show significant coexistence (rcount ; 0.096 < rtable ;0.312), even though the indicator of open-mindedness displayed a significant coherence to learning outcome (rcount ; 0.449 > rtable ;0.312). Based on the result, to sum up, there is a significant relation between critical thinking tendency and critical thinking skills.

Abstract

Background: The ethanol extract of wild cherry (Antidesma bunius L. Spreng) leaves has been studied as a free anti-radical in an emulgel formulation. The purpose of this study is to determine the physical properties of an emulgel made from an ethanol extract of wild cherry leaves, as well as its anti-radical activity. Methods: The maceration method was used to extract wild cherry leaves in 96% ethanol, which were then evaporated with a rotary evaporator. An emulgel was prepared to contain a 3.56% thick extract. The physical properties of the emulgel were evaluated consisting of the organoleptic test, pH test, homogeneity test, spreadability test, and adhesion test. The DPPH was used to test free anti-radical activity. Results: The emulgel of the ethanol extract of wild cherry leaves had a yellowish-green, thick texture, a distinct aroma of the extract, was homogeneous, pH 6, spreadability ranged from 4.4-6.2 cm, and adhesion of 5.5 second. Emulgel had a very weak antioxidant activity with an IC50 of 6238 ppm. Conclusion: Further optimization of the formulation and storage conditions may be required to enhance the antioxidant potential of the wild cherry leaf extract emulgel for topical applications.
