Profil LKS IPA SMP Berorientasi Active Learning dengan Strategi Belajar Mengajukan Pertanyaan

Siswa hanya mendengarkan penjelasan materi dari guru. Selain itu, LKS yang digunakan belum bisa mengaktifkan siswa dalam bertanya dan membuat pertanyaan. Atas dasar itu maka telah dilakukan penelitian pengembangan yang berorientasi pada model 4-D dan bertujuan untuk mendapatkan LKS berorientasi  active learning dengan strategi belajar mengajukan pertanyaan dari aspek struktur penyajian, materi, dan bahasa pada materi Alat Indera Manusia. Sasaran penelitian ini adalah LKS berorientasi  active learning dengan strategi belajar mengajukan pertanyaan. Data dianalisis secara deskriptif kualitatif, dengan hasil telaah baik dan layak digunakan (98,5%) sedangkan hasil respon siswa positif (92,96%). Simpulan bahwa LKS yang dikembangkan layak digunakan.   Kata kunci: model pengembangan 4-D, active learning dengan strategi belajar mengajukan pertanyaan, Alat Indera Manusi

NADES EXTRACT OF GEDONG MANGO LEAVES AND MULBERRY LEAVES IN SPRAY GEL AS A SUNSCREEN

Objective: This study's purpose was to formulate a spray gel containing the combination extract of gedong mango leaves and mulberry leaves as a sunscreen preparation. Methods: Each leaf was extracted by Natural Deep Eutectic Solvent-Maceration Assisted Extraction (NADES-MAE) method. The extract (gedong mango and mulberry leaves) formulated in Carbopol Spray Gel/GM-CarSG) in a ratio of GL and ML were 3:0.5 (GM-CarSG 1); 3:3 (GM-CarSG 2); and 3:6 (GM-CarSG 3). Furthermore, the spray gel was evaluated, and the SPF value was determined. Results: The physical appearance, spreadability, pH, and viscosity of GM-CarSG 1, GM-CarSG 2, and GM-CarSG 3 meet the requirements. In addition, the three preparation have a sunscreen activity, with the SPF value of GM-CarSG 1, GM-CarSG 2, and GM-CarSG 3 being 2.08+0.03; 2.78+0.05; and 3.53+0.04, respectively. Conclusion: The results showed that the combination of GL and ML extract is potentially used as a sunscreen in spray gel preparation. The best formulation is GM-CarSG 3, which has the highest SPF value among them
