Abstract

Penelitian ini bertujuan untuk mengetahui keefektifan penggunaan media Liveworksheets dalam model discovery learning terhadap HOTS (High Order Thinking Skills) peserta didik kelas IX B.i 2 SMP Negeri 6 Makassar (Mata Pelajaran IPA Materi Pewarisan Sifat). Sampel penelitian ini adalah kelas IX B.i 2 yang berjumlah 31 peserta didik. Kegiatan pembelajaran dilaksanakan sebanyak 5 kali pertemuan yang terdiri dari 1 pertemuan pretest, 3 pertemuan proses pembelajaran dan 1 pertemuan posttest. Pengambilan data dilakukan dengan menggunakan tes High Order Thinking Skills (HOTS), dan lembar observasi keterlaksanaan pembelajaran. Data tersebut dianalisis menggunakan analisis statistik deskriptif dan statistik inferensial. Hasil yang dicapai setelah pembelajaran menggunakan media Liveworksheets dalam model discovery learning terhadap High Order Thinking Skills (HOTS), adalah tingkat ketuntatasan perorangan pretest dan posttest peserta didik yaitu bertutut turut sebesar 0% dan 90,32% serta rata-rata nilai gain ternormalisasi hasil belajar adalah 0,68 yang berada pada kategori sedang. Berdasarkan data tersebut, dapat disimpulkan bahwa media Liveworksheets dalam model discovery learning terhadap High Order Thinking Skills (HOTS) efektif terhadap High Order Thinking Skills (HOTS) peserta didik kelas IX B.i 2 SMP Negeri 6 Makassar pada mata pelajaran IPA materi pewarisan sifat.

Abstract

This work investigated the use of acid treatment on the characteristics of zeolite mineral. The effects of treating zeolite with various acid solutions hydrochloric acid (HCl) and sulfuric acid (H2SO4) were measured using x-ray fluorescence (XRF), x-ray diffraction (XRD), and scanning electron microscope (SEM). The results showed an increase in the percentage of SiO2 and Al2O3 after zeolite activation, and also a decrease in the amount of impurities. The crystalline phase of the zeolite was carried out using XRD analysis, indicating the type of zeolite used is modernite. The SiO2 phase in the sample is quartz, and the Al2O3 phase is corundum. The average crystal size decreased after activation, from 14.23 nm to 6.85 nm for HCl and 5.42 nm for H2SO4. Futhermore, the surface morphology of all zeolite samples has a form of irregular spherical surface, and the surface size of the particles after activation shows a smaller particle shape. The results of this study are expected to become recommendations for further research related to natural zeolite pretreatment as a catalyst support.
