Judul: The Correlation between Nutritional Intake, Physical Activity, and Quality of Sleep with Student’s Learning Concentration in SMA Dwiwarna Boarding School Parung
Abstrak: Penelitian ini bertujuan untuk menganalisis hubungan asupan zat gizi, aktivitas fisik, dan kualitas tidur dengan konsentrasi belajar. Studi cross sectional dilakukan pada siswa/i SMA Dwiwarna Islamic Boarding School, Parung, Kabupaten Bogor. Subjek penelitian berjumlah 76 orang yang dipilih secara purposive sampling. Data yang dikumpulkan meliputi data karakteristik individu dan keluarga, asupan zat gizi, tingkat aktivitas fisik subjek, kualitas tidur subjek, dan konsentrasi belajar subjek. Hasil penelitian menunjukkan sebagian besar tingkat kecukupan zat gizi makro dan mikro subjek tergolong kurang. Aktivitas fisik sebagian besar subjek (64,5%) tergolong ringan pada hari sekolah dan (77,6%) tergolong sedang pada hari libur. Hampir seluruh subjek (67,1%) juga memiliki kualitas tidur yang buruk dengan rata-rata skor PSQI 6,9. Hasil penilaian konsentrasi belajar menunjukkan lebih dari setengah subjek (55,3%) memiliki konsentrasi yang kurang dengan rata-rata skor DSST 62,7. Tidak terdapat hubungan yang signifikan antara status gizi, tingkat kecukupan zat gizi, dan aktivitas fisik dengan konsentrasi belajar, tetapi terdapat hubungan signifikan positif antara kualitas tidur dengan konsentrasi belajar subjek., This research aim is to analyze the correlation between nutritional intake, physical activity, and quality of sleep with learning concentration of the subjects. Design of this study was cross sectional study. Subjects of this study were 76 person of Dwiwarna High School Islamic Boarding School, Parung, Bogor District students selected by purposive sampling. The data collected includes data on individual and family characteristics, nutritional intake, the subject’s physical activity level, the subject’s sleep quality, and the subject’s learning concentration. The results showed that most of subject had low macronutrient and micronutrient adequacy level. The average of subject physical activity was low active on school days (64,5%) and moderate active on holidays (77,6%). More than half of subjects (67,1%) had poor sleep quality with an average PSQI score 6,9. Learning concentration assessment results showed more than half of subjects (55,3%) had low level of learning concentration with an average of DSST score 62,7. There was no correlation between nutritional status, nutritional adequacy level, and physical activity with learning concentration of subject, but there is a correlation between quality of sleep with learning concentration.

Judul: Correlation between Eating Habits and Diet Quality with Learning Concentration of Adolescents in SMPN 2 Cibungbulang Bogor
Abstrak: Permasalahan gizi menyebabkan perkembangan otak kurang optimal, berdampak negatif pada fungsi kognitif, kemampuan belajar, konsentrasi dan produktivitas. Penelitian ini bertujuan menganalisis hubungan kebiasaan makan dan kualitas diet dengan konsentrasi belajar remaja di SMPN 2 Cibungbulang. Desain penelitian ini cross sectional study melibatkan 35 siswa kelas VII, dilaksanakan pada Februari-Mei 2024. Data asupan didapatkan melalui food recall 2x24 jam, kualitas diet diukur menggunakan Diet Quality Index for Adolescent (DQI-A), konsentrasi belajar menggunakan Digit Symbol Substitution Test (DSST). Hampir setengah subjek (42,9%) memiliki kebiasaan sarapan 5-7 kali/minggu. Kontribusi energi, protein dan lemak sarapan tergolong cukup, sedangkan karbohidrat kurang. Subjek memiliki kebiasaan makan 3 kali sehari dengan tingkat kecukupan energi, protein dan karbohidrat tergolong defisit, sedangkan lemak tergolong lebih dari rekomendasi. Sekitar tiga perempat subjek (77,1%) memiliki status gizi (IMT/U) baik. Rata-rata skor DQI-A subjek sebesar 36,41% ± 4,35% dan tergolong rendah. Rata-rata skor DSST 37,69 ± 9,37 dan tergolong kurang baik. Tidak terdapat hubungan signifikan antara kebiasaan makan dengan kualitas diet, kualitas diet dengan status gizi dan konsentrasi belajar (p>0,05). Hubungan signifikan ditemukan antara kontribusi energi, lemak dan karbohidrat sarapan serta tingkat kecukupan protein dengan konsentrasi belajar (p<0,05). Penelitian ini memberikan tambahan bukti pentingnya kebiasaan sarapan dan kualitas diet terhadap konsentrasi belajar., Nutritional problems can lead to suboptimal brain development which negatively impact cognitive function, learning ability, concentration, and productivity. This study aims to analyze the relationship between eating habits and diet quality with adolescent learning concentration at SMPN 2 Cibungbulang. The research design was a cross-sectional study involved 35 students of class VII and conducted in February-May 2024. Food intake was obtained through 2x24 hour food recall, diet quality was measured using the Diet Quality Index for Adolescent (DQI-A) and learning concentration using the Digit Symbol Substitution Test (DSST). Almost half of the subjects (42.9%) had breakfast 5-7 times/week. The breakfast energy, protein and fat contribution was adequate, while the breakfast carbohydrates contribution was inadequate. Subjects had the habit of eating 3 times a day with adequacy level of energy, protein and carbohydrates classified as deficit, while fat was classified as over the recommedation. Around three quarters of subject (77,1%) had good nutritional status (IMT/U). The average DQI-A score was 36.41% ± 4.35% and classified as low. The average DSST score was 37.69 ± 9.37 and classified as poor. There was no significant relationship between eating habits and diet quality and diet quality with nutritional status and learning concentration (p>0.05). On the other hand, a significant relationship was found between the breakfast energy, fat and carbohydrates contribution and adequacy level of protein with learning concentration (p<0.05). This research enrich the evidence the importance of breakfast habits and diet quality on learning concentration.

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.
