Judul: Determinan status anemia, aktivitas fisik dan prestasi belajar siswa di SDN Pasanggrahan II Purwakarta
Abstrak: This study was aimed to examine determinant of anemia status, physical activity and academic achievement of students. This research used a cross sectional study. The number of samples were 52 elementary school student. Food consumption recall was used to measure iron source food consumption, academic achievement data was taken from exam semester and linear regression used for analysis determinants. Result showed a large number of children in normal status (51.92%) while the rest was anemia (48.08%). Nutritional knowledge of anemia student and normal student was low. Both anemia (68%) and normal student (55.6%) experience severe energy deficit, physical activity of anemia and normal students was classified as light. Academic achievement of students were very low with the score only below 60. Spearman correlation showed there was no relationship between physical activity with anemia status (p>0.05) and Pearson’s correlation showed there’s no relationship between academic score with anemia status (p>0.05). The result of regression analysis showed that poultry has negative significant effect anemia status.

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: Pembuatan Isoeugenol dari Eugenol Menggunakan Pemanasan Gelombang Mikro
Abstrak: Indonesia merupakan salah satu penghasil minyak cengkeh terbesar di dunia. Pasokan minyak cengkeh Indonesia ke pasar dunia mencapai 60% kebutuhan dunia. Pada tahun 2000, dari 2,080 ton minyak cengkeh yang dipasarkan, Indonesia memasok 1,317 ton (Deptan, 2005). Di negara-negara industri seperti Amerika Serikat, Perancis, Jerman, Italia, dan Inggris, minyak cengkeh digunakan sebagai bahan baku untuk membuat isolat eugenol dan derivatnya seperti isoeugenol dengan nilai tambah yang lebih tinggi. Harga eugenol sebesar Rp 75 000/kg, harga isoeugenol sebesar Rp 95 000/kg (Indesso, 2006) sedangkan harga minyak daun cengkeh Indonesia di pasar Internasional sekitar Rp 25 000/kg (Deptan, 2005). Isoeugenol merupakan senyawa yang banyak digunakan sebagai campuran dalam fragrances dan dalam produk-produk konsumsi harian seperti parfum, produk perawatan kulit, deodoran, sabun, shampo, deterjen serta sebagai bahan intermediet dalam produksi vanilin sintetik. Isoeugenol dihasilkan dari reaksi isomerisasi eugenol. Reaksi isomerisasi eugenol umumnya dilakukan dengan cara mereaksikan eugenol dalam larutan basa KOH atau NaOH pada suhu tinggi selama 5 – 7 jam (Cerveny et al., 1987). Lamanya waktu pemanasan konvensional ini diduga dapat dipersingkat dengan menggunakan pemanasan gelombang mikro. Aplikasi katalis basa yang membutuhkan jumlah yang berlebih dalam reaksi isomerisasi juga dapat digantikan dengan menggunakan katalis RhCl3.3H2O dalam jumlah yang lebih rendah (Chalk, 1977).
