Abstrak: The aims of the study are to examine the influence of multivitamin mineral supplementation on the nutritional status, hemoglobin concentration and physical activity of Bogor Agricultural University First Common Year female students. The previous research showed that Bogor Agricultural University First Common Year female students have a high prevalence of anemia (Briawan 2008). The design of the research was a double blind-quasi experimental. Subjects consisted 27 people who were sistematically allocated into two groups. The first group consisted of 14 people (28.5% anemia), received multivitamin mineral (MVM) and the second group consisted of 13 peopole (38.4% anemia), received placebo (control group). The supplements contained of vitamin B1, B2, B3, B6, B12, vitamin C, Ca, Mn, Fe and Zn which were distributed and consumed everyday during 8 weeks. The data used were primary data in the form of characteristic samples, anthropometry (weight, height and percent body fat), food consumption, level of fitness results of speed (running at 60 meter), endurance and muscle strength (sit-up, push-up and vertical jump), agility (shuttle run 4x10 meter) and VO2max values (bleep test). The results of statistical test (paired samples t-test) showed that there were significant difference of speed (sample at 60 meter of running) (MVM: p>0,060; placebo: p<0,029), push-up (MVM: p<0,008; placebo: p<0,029), sit-up (MVM: p<0,000; placebo: p<0,020) and bleep test (MVM: p<0,011; placebo: p<0,000), but there were no significant difference (p>0,05) in vertical jump and shuttle run test in both MVM and placebo groups.

Judul: Pengaruh Pendidikan Gizi terhadap Kadar Hemoglobin Mahasiswa Putri TPB IPB yang Diberi Suplementasi Multivitamin Mineral
Abstrak: Anaemia is still prevalence in Indonesia especially in adolescent girls because deficiency of iron and folic acid. The purpose of this study was to analyze the effect of multivitamin minerals supplementation and nutrition education on haemoglobin. The study was conducted on First Common Year Studentsof Bogor Agricultural University. Design of the study was Quasy Experimental with pretest post test group. The number of subjects was 27 and allocated into two groups. First group received multivitamin minerals supplementation without nutrition education (S group); second group received multivitamin and minerals supplementation with nutrition education (SPG group). The method of nutition education was speech and allocated into four session with duration 30-45 minutes for each meeting. The result of the study showed that nutrition education affected nutritional knowledge but could not improve nutritional attitudes and nutritional practice. There was no significant correlation between nutrition knowledge, attitude, and practice. Multivitamin minerals supplementation could not improve haemoglobin, but could increased haemoglobin of anaemia subject although the increase was not significant (p>0.05).

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.
