Abstract

Penelitian ini merupakan penelitian eksperimen yang bertujuan untuk mengetahui pengaruh  model  pembelajaran  latihan  inkuiri  berbantuan  google  classroom dimasa pandemi terhadap kemampuan literasi kimia anorganik khususnya materi sifat perioditas unsur dalam sistem periodik. Desain  penelitian  yang  digunakan  adalah  one  group  pretest-posttest  design. Sampel dalam penelitian ini adalah mahasiswa yang memprogramkan mata kuliah kimia anorganik  semester  ganjil tahun akademik  2020-2021 Prodi Pendidikan Kimia FKIP Universitas Khairun., mengunakan teknik pursovise sampling. Teknik analisis data adalah analisis statistik inferensial menggunakan SPSS 20. Hasil Uji hipotesis menunjukkan bahwa  sig 0,05 dan t hitung t tabel maka Ho ditolak  sehingga  dapat  disimpulkan bahwa terdapat  pengaruh  model  pembelajaran latihan inkuiri berbantuan google classroom dimasa pandemi terhadap kemampuan literasi kimia pada matakuliah kimia anorganik khususnya materi sifat  perioditas  unsur  dalam  sistem periodik.   Kata Kunci : Latihan inkuiri, kimia anorganik, literasi kimia, statistik inferensial

Abstract

Nano composite BiOI-Allophane was successfullysynthesized by using hydrothermal reaction method. Theallophane was isolated from Gamalama volcanic soil by usingHenmi method which modified in accordance with theavailability of laboratory equipments. Isolated allophane wasadded into mixtures of 5 mmol Bi(NO3)2 and 5 mmol KI. Acidityof mixtures was maintained at pH 7 by using NH4OH 2M. Themixtures was then put into hydrothermal reactor and heated at180oC for 24 hours. The composite was characterized by usingFTIR, XRD, SEM, and TEM. FTIR spectra shows vibrationsthose are characteristic of BiOI and aluminosilica. XRDdifractogram, SEM and TEM were confirmed that BiOI bindedin allophane framework. The size and the form of BiOIallophanecomposite is heterogeneous nano-ballabout 5 nm.
