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 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: Pengaruh Pendidikan Gizi dengan Media Audio Visual terhadap Pengetahuan dan Sikap tentang Pedoman Gizi Seimbang pada Siswa Sekolah Dasar
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh pendidikan gizi melalui media audio visual berupa video terkait Pedoman Gizi Seimbang (PGS) terhadap pengetahuan dan sikap gizi pada siswa sekolah dasar. Contoh penelitian ditentukan secara purposive sampling, yaitu sebanyak 76 siswa kelas 5 di SDN Panaragan 1 dan 2 Kota Bogor. Tahapan penelitian terdiri dari pre test, intervensi, post test 1, dan post test 2 dengan desain penelitian quasi experimental dengan pretest-posttest control group design. Pengetahuan dan sikap gizi contoh diperoleh menggunakan kuesioner. Hasil analisis dengan uji statistik Wilcoxon pada pengetahuan dan sikap gizi menunjukkan jika media video berpengaruh terhadap peningkatan pengetahuan dan sikap gizi contoh. Pengetahuan gizi contoh meningkat secara signifikan dari 74.5 menjadi 86.9 pada post test 1, dan 82.7 pada post test 2. Sikap gizi contoh meningkat secara signifikan dari 86.9 menjadi 91.5 pada post test 1, dan 90.1 pada post test 2.

Judul: Penyusunan Overlap Graph menggunakan Suffix Tree pada DNA Sequence
Abstrak: The DNA sequence assembly is very important in genome analysis. This step aims to reconstruct contigous DNA fragment (contigs) from short fragment by concatenating fragments based on the overlap region among them. This method employs overlap graph for solving the problems. In this graph, nodes represent fragments and edges represent overlap. This research developed a software for constructing overlap graph using suffix tree. The evaluation was conducted by measuring the number of nodes, number of edges, and the execution time in many values of minimum overlap. The minimum overlap is defined as the minimum length of substring which is considered as the overlap region between two fragments. The evaluation results showed that the number of nodes, the number of edges, and the execution time were increased with the decreasing of the minimum overlap value.
