Judul: Hubungan Aktivitas Fisik, Pengetahuan, dan Tingkat Kecukupan Gizi Dengan Status Gizi Siswa SMP Boarding School
Abstrak: Remaja membutuhkan energi dan zat gizi untuk memenuhi kebutuhan masa pertumbuhan dan aktivitas fisik yang dipengaruhi oleh pengetahuan gizi. Penelitian ini bertujuan menganalisis hubungan aktivitas fisik, pengetahuan, dan tingkat kecukupan gizi dengan status gizi siswa SMP boarding school. Desain penelitian cross sectional study dengan 43 subjek di SMPIT Al Bunyan, Cikaret. Hasil tingkat aktivitas fisik subjek tergolong sangat ringan dan ringan. Pengetahuan gizi berkategori rendah sebanyak 60,5%. Tingkat kecukupan gizi (TKG) berupa energi berkategori cukup 32,6%, berlebih 20,9%, dan defisit 46,5%, protein berkategori cukup 14%, berlebih 9,3%, dan defisit 76,7%, lemak berkategori cukup 18,6%, berlebih 7%, dan defisit 74,4%, serta karbohidrat berkategori cukup 25,6%, berlebih 34,9%, dan defisit 39,5%. Subjek dengan status gizi kurang memiliki TKG yang lebih tinggi dibandingkan dengan status gizi obes. Subjek dengan status gizi obes ternyata mempunyai asupan zat gizi yang rendah pada saat food recall dilakukan. Uji statistik menunjukkan adanya hubungan yang signifikan antara tingkat kecukupan energi (p=0,001, r=-0,484), protein (p=0,000, r=-0,515), dan karbohidrat (p=0,000, r=-0,535) dengan status gizi. Tidak ada hubungan signifikan antara aktivitas fisik, pengetahuan gizi, dan tingkat kecukupan lemak dengan status gizi., Adolescents require energy and nutrients to meet the needs of growth and physical activity which are influenced by nutritional knowledge. This study aims to analyze the relationship between physical activity, knowledge, and the level of nutritional adequacy with the nutritional status of boarding school junior high school students. The research design was a cross sectional study with 43 subjects at Integrated Islamic Junior High School of Al Bunyan, Cikaret. Physical activity level of the subjects were classified very light and light. Nutritional knowledge was categorized low as 60.5%. The nutritional adequacy level (NAL) in the form of energy was categorized sufficient 32.6%, excess 20.9%, and deficit 46.5%, protein was categorized sufficient 14%, excess 9.3%, and deficit 76.7%, fat was categorized sufficient 18.6%, excess 7%, and deficit 74.4%, and carbohydrates was categorized sufficient 25.6%, excess 34.9%, and deficit 39.5%, respectively. The NAL of undernourished subjects were observed to be higher than NAL compared to obese subjects. Subjects with obesity were found to have low intakes nutrients at the time of food recall conducted. The result of this study showed significant correlation between the adequacy level of energy (p=0.001, r=-0.484), protein (p=0.000, r=-0.515), and carbohydrates (p=0.000, r=-0.535) with nutritional status. There was no significant correlation between physical activity, nutritional knowledge, and fat adequacy with nutritional status.

Judul: The Correlation between Nutritional Knowledge, Eating Habits, and Physical Activity with Nutritional Status among Student of SMAN 1 Kebumen
Abstrak: Prevalensi remaja gemuk usia 16-18 tahun di Indonesia meningkat pada tahun 2018. Kegemukan pada remaja dapat menimbulkan dampak negatif terkait aspek kesehatan dan psikososial. Penelitian ini bertujuan menganalisis hubungan pengetahuan gizi dengan kebiasaan makan, hubungan kebiasaan makan dengan status gizi, dan hubungan aktivitas fisik dengan status gizi siswa SMAN 1 Kebumen. Penelitian dilakukan pada Mei 2023 menggunakan desain cross sectional, melibatkan 30 remaja normal dan 30 remaja gemuk yang dipilih secara purposive. Data primer diperoleh melalui pengisian kuesioner dan wawancara berupa data karakteristik individu, karakteristik keluarga, pengetahuan gizi, aktivitas fisik, dan kebiasaan makan. Hasil uji beda menunjukkan tidak terdapat perbedaan signifikan (p>0,05) pengetahuan gizi, aktivitas fisik dan duduk, tingkat kecukupan energi dan zat gizi, asupan gula, serta kebiasaan pangan sumber gula dan lemak antara kedua kelompok subjek, namun kelompok subjek gemuk signifikan lebih banyak asupan lemaknya (p<0,05). Hasil uji korelasi menunjukkan hubungan signifikan positif antara asupan lemak dengan status gizi (p=0,01). Tidak terdapat hubungan signifikan pengetahuan gizi dengan kebiasaan pangan sumber gula dan lemak, asupan gula dan lemak, serta tingkat kecukupan energi dan zat gizi. Tidak terdapat perbedaan signifikan kebiasaan pangan sumber gula dan lemak, asupan gula, tingkat kecukupan energi dan zat gizi, dan aktivitas fisik dengan status gizi (p>0,05)., Prevalence obese adolescents aged 16-18 years in Indonesia increased in 2018. Obesity in adolescents have negative impacts related to health and psychosocial. This study aims to analyze correlation nutritional knowledge and eating habits, correlation eating habits and nutritional status, and correlation physical activity and nutritional status students at SMAN 1 Kebumen. Study was conducted in May 2023 using a cross-sectional design, involving 30 normal and 30 obese adolescents that selected purposively. Primary data was obtained through questionnaires and interviews with individual characteristics, family characteristics, nutritional knowledge, physical activity, and eating habits. There was no significant difference (p>0.05) nutritional knowledge, physical activity and duration of sitting, energy and nutrients adequacy level, sugar intake, and eating habits of food sources sugar and fat between two subject, but obese subjects had significantly higher fat intake (p<0.05). There was a significant positive correlation fat intake and nutritional status (p=0.01). There was no significant correlation nutritional knowledge with eating habits of food sources sugar and fat, intake sugar and fat, also energy and nutrients adequacy level (p>0.05).

Judul: Penerapan teknik watermarking untuk penandaan hak cipta pada peta vektor dengan format DXF
Abstrak: Drawing Interchange Format (DXF) is one of the general file in the field of the vector image commonly used for making maps. The DXF format is a tagged data representation of all the information contained in an AutoCAD drawing (DWG) file. Tagged data means that each data element in the watermark is preceded by an integer number called the group code. The study was carried out because there is still no tools of labeling the copyright on digital mapping using DXF file. This study aims to generate an application for copyright labeling on vector map with DXF format that can be applied to any types of spatial objects in the map. The technique used is changing the code inside the vector image. The insertion of the watermark is done by utilizing ENTITIES section by multiplying objects for sets of binary values. The results showed that the image after the watermarking insertion process is the same as the original vector image. Embedded watermark is resistant to rotation and scaling, however it has the possibility of one-third to be broken in the attack on specific object. This study has successfully implemented watermarking technique for copyright labeling on the vector map with DXF format.
