Abstrak: Permasalahan gizi pada anak usia sekolah dapat dikurangi dengan pengenalan Pedoman Gizi Seimbang (PGS). Media pendidikan gizi penting terutama pada kondisi proses pembelajaran di rumah. Penelitian ini bertujuan untuk mempelajari pengaruh media pembelajaran audiovisual terhadap pengetahuan dan sikap terkait Pedoman Gizi Seimbang (PGS) pada siswa sekolah belajar di rumah. Desain penelitian ini adalah quasi experimental design with one group pre and post test. Penelitian ini dilakukan pada Oktober–November 2020 di Sekolah Dasar Islam Az-Zahrah, Kota Palembang dengan jumlah contoh sebanyak 50 orang yang dipilih secara purposive sampling. Tahapan penelitian diawali dengan pre-test, intervensi, post-test I, dan post-test II. Hasil penelitian menunjukkan bahwa media pembelajaran audiovisual berpengaruh terhadap peningkatan pengetahuan dan sikap terkait PGS. Hasil uji beda menunjukkan hasil perbedaan yang signifikan antara pengetahuan gizi pre-test dan post-test I (p=0,024, p<0,05), sikap gizi pada pre-test dan post-test I (p=0,025, p<0,05), dan sikap gizi pada pre-test dan post-test II (p=0,074, p<0,10)., The introduction of Balanced Nutrition Guidelines can help to prevent problems in school-aged children. Media for nutrition education is criticaly important, particularly in the context of home based learning. The purpose of this study is to analyze the effect of audiovisual learning media on knowledge and attitudes related to Balanced Nutrition Guidelines in home learning students. The design of this study is Quasi experimental design with one group pre and post test. The study start from October to November 2020 at Az-Zahrah Islamic Elementary School in Palembang City, with a total sample size of 50 participants chosen by purposive sampling. The research was divided into four stages: pre-test, intervention, post-test I, and post-test II. The research showed that audiovisual learning media increased knowledge and attitudes about PGS. The result of the different tests showed significant difference in nutrition pre-test and post-test I (p=0.024, p<0.05), nutritional attitudes pre-test and post-test I (p=0.025, p<0.05), and nutritional attitudes pre-test and post-test II (p=0.074, p<0.10).

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
