Judul: Correlation between Food Consumption, Iron Intake, and Physical Activity with the Nutritional Status of Female Adolescents at the Tarbiyatun Nisa Islamic Boarding School, Bogor Regency
Abstrak: Remaja memiliki tingkat konsumsi makanan padat energi, dan persentase makan buah dan sayuran yang rendah. Penelitian ini bertujuan untuk menganalisis hubungan antara konsumsi pangan, asupan zat besi, dan aktivitas fisik dengan status gizi remaja putri di Pondok Pesantren Tarbiyyatun Nisa Kabupaten Bogor. Penelitian ini dilaksanakan pada bulan Februari 2023 pada 87 subjek dengan desain studi cross sectional. Pengambilan data meliputi pengukuran tinggi badan, berat badan, wawancara, serta pengisian kuesioner yang meliputi biodata, karakteristik sosioekonomi keluarga, recall konsumsi pangan 2x24 jam, dan recall aktivitas fisik 2x24 jam. Sebagian besar subjek memiliki status gizi normal (73,6%). Rata-rata level aktivitas fisik subjek pada weekday sebesar 1,4 (ringan), sedangkan pada weekend sebesar 1,5 (ringan). Rata-rata tingkat kecukupan zat gizi subjek yaitu energi sebesar 84%, protein sebesar 83%, lemak sebesar 56%, karbohidrat sebesar 86%, zat besi sebesar 96%. Hasil penelitian menunjukkan bahwa aktivitas fisik dan status gizi remaja putri di Pondok Pesantren Tarbiyatun Nisa memiliki hubungan yang signifikan (p = 0,022; r = -0,671). Sementara itu, tidak terdapat hubungan signifikan antara tingkat kecukupan zat besi dengan status gizi, demikian pula tingkat kecukupan zat gizi lainnya dengan status gizi dan dengan aktivitas fisik (p > 0,050)., Adolescents have a high consumption of energy-dense foods, and a low proportion of fruits and vegetables. This study aims to analyze the relationship between food consumption, iron intake, and physical activity with the nutritional status of young women at the Tarbiyyatun Nisa Islamic Boarding School, Bogor Regency. This research was conducted in February 2023 on 87 subjects with a cross sectional study design. Data collection included measuring height, weight, interviews, and filling out questionnaires which included biodata, family socioeconomic characteristics, 2x24 hour food consumption recall, and 2x24 hour physical activity recall. Most of the subjects had normal nutritional status (73.6%). The average level of physical activity on weekdays is 1.4 (mild), while on weekends it is 1.5 (mild). The average level of nutritional adequacy of the subjects, namely energy by 84%, protein by 83%, fat by 56%, carbohydrate by 86%, iron by 96%. The results showed that physical activity and nutritional status of young women at the Tarbiyatun Nisa Islamic Boarding School had a significant relationship (p = 0.022; r = -0.671). Meanwhile, there was no significant relationship between the level of iron adequacy and nutritional status, as well as the level of adequacy of other nutrients with nutritional status and physical activity (p> 0.050).

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: 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.
