Judul: Hubungan Status Gizi, Asupan Zat Gizi, dan Aktivitas Fisik dengan Kebugaran Anak Sekolah di SDN 2 Pasanggrahan Purwakarta.
Abstrak: About 2/3 of children have sedentary lifestyle, especially in developing countries that will affect fitness level. The purpose of this study was to analyze the relations of nutritional status, nutrient intake, and physical activity to fitness of school children. This study used a case study with a sample of 53 students. Fitness levels were measured through a multi stage run test (bleep test). Data processed by Microsoft Excel 2007 and analyzed using the Statistical Program for Social Science (SPSS) 16.0 for Windows. There were no significant differences (p>0.05) between gender, age, and pocket money of sample with nutritional status and physical activity of sample. While there were a significant differences (p<0.05) between sex and age with sufficient levels of vitamin and mineral samples. The results showed that there were a significant correlations (p <0.05) between age and iron intake with the level of fitness. There were a significant differences (p<0.05) on gender, consumption of vegetables, protein intake, and physical activity of the samples fit and unfit. Based on linear regression analysis showed that age and iron intake have a significantly affecting (p>0.05) samples fitness level.

Judul: The Relationship between Fruit Vegetable Consumption Habits and Physical Activity with Nutritional Status and Physical Fitness of Students at SDN 1 Cijeungjing
Abstrak: Status gizi kurang dan lebih merupakan salah satu masalah gizi yang banyak dihadapi pada usia anak sekolah dasar. Status gizi dapat dipengaruhi oleh berbagai faktor seperti pengetahuan gizi, aktivitas fisik, kebugaran, dan kebiasaan makan. Tujuan penelitian ini adalah menganalisis hubungan kebiasaan konsumsi sayur dan buah serta aktivitas fisik dengan status gizi dan kebugaran jasmani siswa di SDN 1 Cijeungjing. Penelitian ini dilaksanakan pada bulan Oktober-November 2022 pada 58 subjek dengan desain cross sectional study. Pengambilan data dilakukan melalui pengukuran tinggi badan dan berat badan, wawancara, harvard step test, pengisian kuesioner meliputi karakteristik subjek dan keluarga, PAQ-C (Physical Activity Questionnaire for Children), dan FFQ (Food Frequency Questionnaire). Sebagian besar subjek berjenis kelamin laki-laki (72,4%) dengan status gizi normal (79,3%). Hasil analisis menunjukkan terdapat hubungan yang signifikan (p<0,05) antara kebiasaan konsumsi sayur dan buah dengan aktivitas fisik (p-value=0,050;r=-0,129). Terdapat hubungan yang signifikan (p<0,05) antara aktivitas fisik dengan kebugaran jasmani (p-value=0,029;r=0,288). Namun, tidak terdapat hubungan yang signifikan (p>0,05) antara kebiasaan konsumsi sayur dan buah dengan status gizi (p-value=0,338;r=0,128). Tidak terdapat hubungan yang signifikan (p>0,05) antara aktivitas fisik dengan status gizi (p-value=0,142;r=0,195). Tidak terdapat hubungan yang signifikan (p>0,05) antara kebiasaan konsumsi sayur dan buah dengan kebugaran jasmani (p-value=0,333;r=-0,129)., Underweight and overweight are one of the most common nutritional problems faced by elementary school children. Nutritional status can be influenced by various factors such as nutritional knowledge, physical activity, fitness, and eating habits. The aim of this study was to analyze the relationship between fruit vegetable consumption habits and physical activity with the nutritional status and physical fitness of students at SDN 1 Cijeungjing. This study was conducted in October-November 2022 on 58 subjects with a cross-sectional study design. Data collected by measuring height and weight, interviews, harvard step test, filling out questionnaires including subject and family characteristics, PAQ-C questionnaire (Physical Activity Questionnaire for Children), and FFQ questionnaire (Food Frequency Questionnaire). Most subjects were male (72.4%) with normal nutritional status (79.3%). The results of the analysis showed that there was a significant correlation (p<0.05) between fruit vegetables consumption habits with physical activity (p-value=0.050;r=-0.129). There was significant correlation (p<0.05) between physical activity with physical fitness (p-value=0.029;r=0.288). However, there was no significant correlation (p>;0.05) between fruit vegetables consumption habits with nutritional status (p-value=0.338;r=0.128). There was no significant correlation (p>0.05) between physical activity with nutritional status (p-value=0.142;r=0.195). There was no significant correlation (p>0.05) between fruit vegetables consumption habits with physical fitness (p-value=0.333;r=-0.129).

Judul: Sintesis 1-Kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai Prekursor Asam (S)-(+)-(6-Metoksi-2-naftil)propanoat
Abstrak: Senyawa 1-kloro-2-metoksi-6-propilnaftalena-1,3-dioksolana (1:1) sebagai prekursor asam (S)-(+)-(6-metoksi-2-naftil)propanoat disintesis dari bahan awal 2-metoksinaftalena. Tahapan sintesis diawali dengan klorinasi menggunakan 2 jenis pereaksi klorinasi, yakni isosianurat terklorinasi dan NaOCl. Klorinasi dengan isosianurat terklorinasi berhasil menyintesis 1-kloro-2-metoksinaftalena sebagai produk monoklorinasi melalui pencirian dengan kromatograf gas-spektrometer massa (GC-MS). Nisbah konversi produk paling efisien diperoleh pada laju penambahan 2.5 mmol/jam. Sebaliknya, klorinasi dengan NaOCl menghasilkan produk triklorinasi. 1-Kloro-2-metoksinaftalena selanjutnya diasilasi dengan propanoil klorida, tetapi analisis dengan GC menunjukkan bahwa produk asilasi tidak terbentuk. Sistem bebas-air diperlukan untuk keberhasilan proses asilasi tersebut.
