Judul: Correlation between Stress Level, Physical Activity, Sleep Duration, Eating Habit, and Nutritional Status in Final Year Students
Abstrak: Masalah yang sering ditemui pada mahasiswa tingkat akhir adalah stres karena mengerjakan skripsi, sehingga memengaruhi pola makan, penurunan aktivitas fisik, dan durasi tidur yang pendek. Penelitian ini bertujuan menganalisis hubungan stres, aktivitas fisik, durasi tidur, dan pola makan terhadap status gizi pada mahasiswa IPB tingkat akhir. Penelitian dilakukan pada bulan Mei–Juni 2023 pada 55 mahasiswa dengan studi cross sectional. Hasil penelitian menunjukkan sejumlah 34,5% mahasiswa mengalami stres tingkat ringan, 58,2% aktivitas fisik ringan, 80% mahasiswa memiliki durasi tidur kurang, dan sebagian besar mahasiswa memiliki rata-rata tingkat kecukupan gizi defisit. Hasil analisis korelasi rank Pearson menunjukkan terdapat hubungan signifikan bersifat positif antara aktivitas fisik dengan status gizi, dan hubungan signifikan bersifat negatif antara tingkat kecukupan energi, tingkat kecukupan protein, tingkat kecukupan lemak, dan tingkat kecukupan karbohidrat dengan status gizi (p<0,05). Tidak terdapat hubungan signifikan antara tingkat stres dan durasi tidur dengan status gizi (p>0,05)., The problem that is often encountered in final year students is stress from working on thesis, which affects eating habit, decreased physical activity, and short sleep duration. This study aims to analyze the relationship between stress, physical activity, sleep duration, and eating habit on the nutritional status of final year IPB students. The research was conducted in May–June 2023 on 55 students with a cross sectional study. The results showed that 34,5% of students experienced mild levels of stress, 58,2% had light physical activity, 80% of students had less sleep duration, and most students had an average deficit nutritional adequacy level. The results of Pearson's rank correlation analysis showed that there was a significant positive relationship between physical activity and nutritional status, and a significant negative relationship between energy adequacy level, protein adequacy level, fat adequacy level, and carbohydrate adequacy level with nutritional status (p<0,05). There is no significant relationship between stress levels and sleep duration with nutritional status (p>0,05).

Judul: The Correlation between Stress Score, Eating Habit and Nutritional Status of Final Year Sudents
Abstrak: Mahasiswa tingkat akhir sering mengalami stres karena mengerjakan skripsi, sehingga dapat memengaruhi pola makan dan status gizi. Penelitian ini bertujuan menganalisis hubungan nilai skor stres, pola makan dan status gizi pada mahasiswa tingkat akhir. Desain penelitian menggunakan studi cross sectional melibatkan 30 subjek. Penelitian dilakukan November 2019 hingga Maret 2020 di Fakultas Ekologi Manusia IPB. Data yang dikumpulkan adalah karakteristik individu dan keluarga, nilai skor stres, pola makan, dan status gizi. Data nilai skor stres dikumpulkan menggunakan kuesioner Depression Anxiety Stress Scales 42 (DASS 42), sedangkan data pola makan dikumpulkan menggunakan Food Frequency Questionnaire (FFQ) dan recall 2 x 24 jam. Hasil penelitian menunjukkan pola makan sebagian besar subjek belum sesuai panduan gizi seimbang. Sebagian besar subjek memiliki rata-rata tingkat kecukupan gizi defisit, 83,3% subjek berstatus gizi normal dan 63,3% subjek memiliki nilai skor stress terkategori stres sedang. Terdapat hubungan signifikan negatif antara nilai skor stres dengan asupan energi (p<0,05), artinya semakin tinggi nilai skor stres mahasiswa, asupan energi subjek semakin rendah. Tidak terdapat hubungan pola makan dengan status gizi (p<0,05), demikian pula tidak terdapat hubungan antara nilai skor stres dengan status gizi (p>0,05)., Final-year students often experience stress because they work on their thesis, which may affect their eating habits and nutritional status. This study analyzes the relationship between stress scores, eating habits, and final year students' nutritional status. The study used a cross-sectional study design involving 30 subjects. The research was conducted from November 2019 to March 2020 at the Faculty of Human Ecology, IPB. The data collected were individual and family characteristics, stress scores, eating habits, and nutritional status. Stress score data were collected using the Depression Anxiety Stress Scales 42 (DASS 42) questionnaire while eating habit data were collected using the Food Frequency Questionnaire (FFQ) and 2 x 24-hour recall. The results showed that the diet of most of the subjects did not comply with balanced nutrition guidelines. Most of the subjects had an average nutritional adequacy deficit, 83.3% of subjects with normal nutritional status, and 63.3% had stress score categorized as moderate stress levels. There is a significant negative relationship between the stress score and energy intake (p <0.05), meaning that the higher the students stress score the lower the energy intake. There is no relationship between eating habits and nutritional status (p<0.05), as well as no relationship between stress scores and nutritional status (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.
