Judul: Correlation between Breakfast Habits and Protein Intake with Nutritional Status and Learning Achievement of Junior High School Students in Cirebon
Abstrak: Sarapan merupakan sumber energi bagi otak untuk membantu proses belajar. Penelitian ini bertujuan untuk menganalisis keterkaitan hubungan antara kebiasaan sarapan dan asupan protein terhadap status gizi dan prestasi belajar siswa tingkat SLTP di Cirebon. Penelitian cross-sectional ini melibatkan 68 subjek yang dipilih secara purposive. Subjek merupakan siswa kelas 7 dan 8 MTs Negeri 02 Cirebon. Pengumpulan data dilakukan melalui pengisian kuesioner dan wawancara secara langsung. Mayoritas subjek memiliki prestasi belajar kategori kurang, status gizi normal, frekuensi sarapan 4,6±1,7 kali/minggu, kontribusi energi sarapan 18,7±6,2% AKE, dan kontribusi protein harian 8,1±3,0 %AKE. Subjek dengan prestasi belajar baik pendidikan ayah dan pendapatan keluarganya signifikan lebih tinggi dibandingkan subjek dengan prestasi belajar kurang. Terdapat hubungan signifikan positif antara kontribusi energi sarapan terhadap status gizi subjek (p=0,028, r=0,267). Tidak terdapat hubungan signifikan (p>0,05) antara kebiasaan sarapan, konsumsi pangan, dan status gizi terhadap prestasi belajar. Namun demikian, sebagian besar subjek dengan prestasi belajar baik memiliki kontribusi energi dari sarapan yang cukup serta melaksanakan sarapan setiap hari sebelum pukul 09.00. Hal ini menunjukan bahwa semakin tinggi kontribusi energi sarapan, semakin tinggi nilai z-score dalam kategori normal. Hal ini menunjukkan sarapan perlu ditingkatkan untuk memenuhi kebutuhan zat gizi dan meningkatkan prestasi belajar., Breakfast is one of source of energy for brain to perform better of learning process. This research aimed to analyzed correlation between breakfast habits and protein intake with nutritional status and learning achievement among junior high school student. This cross-sectional study involved 68 subjects. Data was collected by filling out questionnaires and direct interviewed. Most of the subjects had fair learning achievement, normal nutritional status, breakfast frequency 4.6±1.7 times/week, breakfast energy contribution 18.7±6.2% RNA, and daily protein contribution 8.1±3.0 % RNA. Subjects with good learning had significantly higher father's education and family income than subjects with fair learning achievement. There was positive significant correlation (p=0.028, r=0.267) between breakfast energy contribution and the nutritional status of the subjects. There was no significant correlation (p>0.05) between breakfast habits, food consumption, and nutritional status with learning achievement. However, most of the subjects with good learning achievement had sufficient breakfast energy contribution and had breakfast every day before 09.00 AM. This result showed that the higher energy contribution of breakfast, the higher z-score in the ranged of normal nutritional status category. These indicated that breakfast needed to be improved to fulfill the nutrients requierement and improve learning achievement of students.

Judul: Correlation between Breakfast and Snacking Habits of Adolescents in Cirebon City
Abstrak: Penelitian bertujuan menganalisis hubungan kebiasaan sarapan dan jajan dengan status gizi remaja di Kota Cirebon. Penelitian comparative cross-sectional study ini melibatkan 92 subjek (46 subjek gemuk dan 46 subjek berstatus gizi normal). Data karakteristik subjek dan keluarga, kebiasaan sarapan, dan kebiasaan jajan diperoleh melalui wawancara menggunakan kuesioner. Data antropometri diperoleh dengan pengukuran secara langsung. Hasil penelitian menunjukkan tingkat pendidikan orang tua signifikan lebih tinggi dan kontribusi energi sarapan signifikan (p<0,05) lebih rendah pada subjek gemuk dibandingkan dengan subjek status gizi normal. Mayoritas subjek gemuk (43,5%) jarang mengonsumsi sarapan sedangkan mayoritas subjek status gizi normal (37,0%) selalu mengonsumsi sarapan. Kontribusi sarapan sebagian besar subjek gemuk (52,2%) adalah kurang sedangkan pada subjek normal (54,3%) adalah sedang. Frekuensi jajan subjek gemuk (60,9%) dan normal (52,2%) memiliki frekuensi jajan sering (>2 kali/minggu) sedangkan kontribusi energi jajanan tinggi untuk subjek gemuk dan sedang untuk subjek berstatus gizi normal. Tidak terdapat hubungan signifikan (p>0,05) antara karakteristik keluarga dengan kebiasaan jajan, kebiasaan sarapan dengan kebiasaan jajan, kebiasaan jajan dengan status gizi, dan frekuensi sarapan dengan status gizi, tetapi terdapat hubungan signifikan positif (p=0,01; r=0,22) antara kontribusi energi sarapan dengan status gizi. Hasil ini mengindikasikan semakin tinggi kontribusi energi sarapan, maka semakin normal status gizi subjek., This research aimed to analyze correlation between breakfast and snacking habits with nutritional status of adolescents in Cirebon City. This comparative cross-sectional study involved 92 subjects (46 subjects of each overweight/obese (OWO) and normal nutritional status). Characteristics of subject and their family, breakfast and snacking habits data were obtained through interviewed, anthropometric data were obtained from direct measurements. The results showed that parental education level was significant higher and breakfast energy contribution was significant lower (p<0.05) of OWO subject than normal. Most of OWO subjects rarely consume breakfast while most of normal subjects always consume breakfast. The breakfast energy contribution of most OWO and normal subjects was categorized as low and moderate, respectively. The frequency of snacking of both subjects was mostly frequent (>2 times / week) while snack energy contribution of OWO and normal subjects were high and moderate, respectively. There was no significant relationship (p>0.05) between family characteristics and snacking habits, breakfast and snacking habits, snacking habits and nutritional status, and breakfast frequency and nutritional status, but there was positive significant relationship (p=0.01; r=0.22) between breakfast energy contribution and nutritional status. These indicated that higher the breakfast energy contribution, the more normal the nutritional status of the subjects.

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.
