Judul: The effect of micronutrient supplementation on the iron status and physical fitness of the woman workers at reproductive age
Abstrak: Nowadays, there are many companies employing women as their main workers. In general, the aims of the study are to examine the influence of micronutrients on iron status (hemoglobin, hematocrit, serum ferritin and serum transferin receptor), and to assess the physical fitness (VO2max) of woman workers whose hemoglobin levels were 80 to 125 g/l or marginal and worked at the activity levels classified as moderate to active. The preliminary research was conducted by a survey method with a sample size of 338 households. This research employed an experimental design of double blind, completely randomized design. The experimental unit, taken from the preliminary study, consisted of 39 non-pregnant woman workers of reproductive age whose hemoglobin levels were 80 to 125 g/l or marginal. However, five of them were drop out due to pregnancy or sickness. The treatments applied in the study were by providing three levels of capsules containing: (1) a combination of iron and folic acid (BF), (2) multi-vitamin and mineral (MVM) which contains 15 different vitamins and minerals, and (3) placebo (P) which does not contain vitamins and minerals. The research result showed that the iron status of the woman workers was getting better after the supplementation. The three times per week supplementation with BF could significantly improve Hb 18.2 g/l and SF 10.1 ug/l, while the MVM could increase Hb 16.4 g/l and SF 2.4 ug/l. The increase of Hb levels in group BF and MVM was significantly different from that in group P, but the increase of SF levels was not significantly different among the three groups. The supplements of BF and MVM could significantly improve the physical fitness (VO2max) of the anemia (Hb<120 g/l) woman workers by 12.5% and 13.7%.

Judul: Pengaruh suplementasi multivitamin mineral terhadap status gizi, kadar hemoglobin dan tingkat kebugaran fisik mahasiswi TPB IPB
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: Formulasi Algoritme Operasi Grup Jacobian Kurva Hyperelliptic ...
Abstrak: Dalam geometri aljabar, kurva hyperelliptic merupakan bentuk umum dari kurva elliptic. Kurva ini apabila dikenakan pada suatu lapangan berhingga akan membentuk suatu grup siklik. Pada kriptografi, khususnya enkripsi kunci publik, grup siklik yang dibangkitkan oleh kurva elliptic sudah banyak diteliti. Bahkan untuk kurva ini sudah memiliki standar oleh National Institute of Standard and Technology (NIST) Amerika. Sedangkan, untuk grup yang dibangkitkan oleh kurva hyperelliptic masih memiliki kekurangan dalam hal komputasinya. Tujuan dari penelitian ini adalah mengkonstruksi suatu lapangan berhingga pada , memilih kurva hyperelliptic atas lapangan hingga yang memenuhi kriteria keamanan untuk kriptografi, dan membuat formulasi operasi grup kurva hyperelliptic menggunakan algoritme Cantor. Dalam merekonstruksi lapangan hingga, terlebih dahulu tentukan dimensi dari lapangan hingga tersebut dan polinomial tak-teruraikan. Kemudian dipilih kurva hyperelliptic atas lapangan tersebut. Pada penelitian ini, kurva yang dipilih adalah = + + dengan lapangan hingga . Berdasarkan kurva yang dipilih, akan dibentuk suatu operasi grup dengan menggunakan algoritme Cantor, sehingga menjadi lebih aritmatik. Eksplorasi kurva hiperelliptic dilakukan untuk mengetahui keamanan dari kurva yang dipilih. Dengan menyusun algoritme operasi grup dari kurva yang dipilih, diperoleh perhitungan yang lebih aritmatik dan dapat diimplementasikan pada kriptografi kunci publik. Dari segi keamanan kurva telah memenuhi standar sehingga tahan terhadap serangan-serangan seperti Poligh-Hellman, Polard- , ataupun Frey-Ruck secara teorema.
