چکیده
Penelitian ini bertujuan untuk mengembangkan media pembelajaran program simulasi ekstraksi pelarut dan spektrofotometri UV-Vis pada logam lantanida menggunakan ekstraktan 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone berbasis Microsoft Excel, serta menguji kelayakan tanggapan mahasiswa terhadap yang dikembangkan. Jenis penelitian digunakan adalah pengembangan (RD), dengan tujuh langkah yaitu; (1) potensi masalah, (2) pengumpulan data, (3) desain produk, (4) validasi desain, (5) revisi (6) uji coba (7) produk. Instrumen penilaian terdiri dari angket media, system usability scale (SUS). dilakukan kepada 25 orang Jurusan Pendidikan Kimia Fakultas Keguruan Ilmu Universitas Syiah Kuala. Media diuji telah divalidasi oleh validator persen sebesar 85,00% kategori sangat layak. Respons baik rata-rata 88,35%, skor SUS didapat 85,30 dapat diterima, artinya Excel mensimulasi praktikum mengenai 1-phenyl-3-methyl-4-benzoyl-5-pyrazolone.

Synergistic Solvent Extraction of Trivalent Lanthanoids with Mixtures of 1-Phenyl-3-methyl-4-benzoyl-5- pyrazolone and Crown Ethers
The synergistic solvent extraction of 14 trivalent lanthanoids (except Pm) with 1-phenyl-3-methyl-4-benzoyl-5pyrazolone(HP) and dibenzo-18-crown-6 (DB18C6) or dibenzo-24-crown-8(DB24C8) in 1, 2-dichloroethane has been studied. It was found that in the presence of HP alone the lanthanoids have been extracted as LnP3∙HP and in the presence of mixtures of HP and crown ethers (S) − as LnP3∙S. On th...
