Judul: Knowledge and Attitude of Students to Homebase Learning Students Related to Balanced Nutrition Guidelines Using Audiovisual Learning Media
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 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: The Effect of Nutrition Education through Nutri-c Media and Lecture Methods on Knowledge and Attitudes of Balanced Nutrition in Elementary School Students
Abstrak: Pendidikan gizi seimbang menjadi salah satu upaya untuk meningkatkan penerapan Pedoman Gizi Seimbang (PGS) pada anak usia sekolah. Penelitian ini bertujuan menganalisis pengaruh pemberian pendidikan gizi seimbang melalui media nutri-c terhadap pengetahuan dan sikap gizi siswa sekolah dasar. Penelitian ini menggunakan desain quasi experimental yang dilaksanakan pada bulan Maret-Mei 2023 di SDN Ciherang 04, Kabupaten Bogor. Subjek merupakan siswa kelas 5 SD dengan jumlah 44 orang yang dipilih secara purposive dan dibagi ke dalam dua kelompok penelitian. Kelompok intervensi 1 mendapatkan intervensi menggunakan media nutri-c sedangkan kelompok intervensi 2 menggunakan metode ceramah. Hasil uji beda Wilcoxon menunjukkan terdapat perbedaan pengetahuan gizi seimbang yang signifikan setelah intervensi pada kelompok intervensi 1 (p=0,000). Tidak terdapat perbedaan yang signifikan terkait sikap gizi seimbang setelah intervensi pada kelompok intervensi 1 (p=0,063). Perbedaan pengetahuan (p=0,000) dan sikap (p=0,002) gizi seimbang sebelum dan setelah intervensi pada kelompok intervensi 2 menunjukkan hasil yang signifikan. Media nutri-c lebih efektif meningkatkan pengetahuan subjek. Hasil uji beda Mann Whitney U menunjukkan tidak terdapat perbedaan yang signifikan terkait pengetahuan (p=0,924) dan sikap (p=0,212) gizi seimbang antara kelompok penelitian. Tidak terdapat hubungan yang signifikan antara pengetahuan dengan sikap gizi seimbang subjek setelah mendapatkan intervensi berdasarkan hasil uji korelasi Spearman (p<0,05)., Balanced nutrition education is one of the efforts to improve the implementation of Balanced Nutrition Guidelines (PGS) for school-age children. This study aimed to analyze the effect of providing balanced nutrition education through nutri-c media on the nutritional knowledge and attitudes of elementary school students. This study used a quasi-experimental design which was conducted from March to May 2023 at SDN Ciherang 04, Bogor Regency. The subjects were 5th grade elementary school students with a total of 44 people selected purposively and divided into two research groups. The intervention group 1 received intervention using nutri-c media while the intervention group 2 used the lecture method. The results of the Wilcoxon differential test showed that there were significant differences in knowledge of balanced nutrition after the intervention in the intervention group 1 (p=0.000). There was no significant difference regarding the attitude of balanced nutrition after the intervention in the intervention group 1 (p=0.063). Differences in knowledge (p=0.000) and attitudes (p=0.002) about balanced nutrition before and after the intervention in the intervention group 2 showed significant results. Nutri-c media is more effective in increasing subject knowledge. The results of the Mann Whitney U test showed that there were no significant differences in knowledge (p=0.924) and attitude (p=0.212) to balanced nutrition between the study groups. There was no significant relationship between knowledge and balanced nutrition attitudes of the subjects after receiving the intervention based on the results of Spearman's correlation test (p<0.05).

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.
