Abstract

One of the abilities that students must master in the 21st century is literacy skills, one of which is geographic literacy. Based on previous research, students' geographic literacy, in general, still needs to improve. This research aims to determine and analyze the geographic literacy abilities of State High School (SMA) students in Jambi City. This research uses a survey method. The data processing results show that the geographic literacy skills of 190 State High School students in Jambi City are in the medium category with a percentage of 51% or 97 students. This means the students can understand the essence of interaction, interconnection, and the contextual implications of spatial interaction phenomena in life. Daily for some instances only. Meanwhile, the number of students in the high geographical literacy category is 43 or 23%, so it can be interpreted that students can understand the essence of interaction, interconnection and the implications of spatial interaction phenomena contextually in everyday life. Geographic literacy skills in the low category are 50 students or 26%, which means that students still need to understand the essence of interaction, interconnection and the implications of spatial interaction phenomena contextually in everyday life.

Abstract

Kulit buah naga merah (Hylocereus polyrhizus Britton & Rose) mengandung senyawa flavonoid, fenol dan betasianin sebagai senyawa aktif antioksidan. Penggunaan kulit buah naga merah dapat dimanfaatkan sebagai alternatif pengembangan sediaan topikal seperti krim. Penelitian ini bertujuan untuk mengetahui komposisi optimum cera alba dan vaselinum album basis pembawa ekstrak kulit buah naga merah. Optimasi menggunakan software Design Expert versi 13 dengan metode Simplex Lattice Design (SLD). Respon uji yang digunakan meliputi respon uji pH, viskositas, daya sebar, dan daya lekat. Percobaan menunjukkan hasil formula optimum krim dengan nilai desirability 0,176 dengan konsentrasi cera alba sebesar 2,47% dan vaselinum album sebesar 7,53%. Hasil respon uji berturut-turut untuk uji pH sebesar 5,71±0,0005; viskositas 26480±351,57 cps, uji daya sebar sebesar 4,42±0,21 cm2, dan uji daya lekat sebesar 73,80±12,19 detik.
