Judul: The Relationships between prohepcidin concentration and iron status on anemic adolescent girls
Abstrak: This research was carried out from june 2010 to January 2011 at MTs Fathusa’adah, Sukaraja and SMP Purnawarman, Rancabungur Kabupaten Bogor. The purpose of the research is to know the relationship between prohepcidin serum concentration and iron status of anemic adolescent girls which recieved iron intervention. The research samples consisted of 55 of girl students which divided into two groups. The first group (traetment group/TG) recieved iron capsule (60 mg iron + 0.25 mg folic acid), the second group (control group/CG) only recieved placebo. The capsules were distributed and consumed twice weekly during 12 weeks. The result showed that before and after treatment energy, protein and nutrients (vitamin A, vitamin C, iron) consumption were very low (<70% Recommanded Dietary Allowans (RDA)). After 12 weeks intervention the Hb were significantly increased (P<0.05) as much as 0.65 ± 0.55 g/dl in the TG, but CG decreased 0.05 ± 0.32 g/dl. The result from multiple regretion analysis (MRA) showed that the change of the Hb concentration were influenced by initial Hb concentration and the consumtion of iron (R(adj)=41.6%). There were a significant increased (P<0.05) of feritin serum on the TG as much as 8.42 ± 18.89 ng/ml, and decreased significanly on CG as much as -7.93 ± 14.87 ng/ml. The change of the feritin serum concentration corelated with the initial feritin serum concentration and consumtion of iron (from MRA, R(adj)=40.6%). The mean of the prohepcidin serum concentration before intervention was 192.77 ± 126.98 ng/ml for TG and 203.91 ± 133.32 ng/ml for CG and after intervention 158.93 ± 74.77 ng/ml for TG and 169.93 ± 81.11 ng/ml for CG, but the decrease was not significant. Result from multiple regretion analysis showed that the change of prohepcidin were influenced by initial prohepcidin concentration and the consumtion of energy and protein (R(adj) = 73,8%) and were not corelated with iron status.

Judul: Food Consumption, Knowledge, Attitudes, and Practices related to Anemia and Iron-Folic Acid Supplementation on Anemia Status of Adolescent Girls
Abstrak: Adolescent girls are at high risk of anemia due to unmet nutritional needs and low compliance to the government's folate-iron supplementation program. This study investigates the differences in food consumption, knowledge, attitudes, and practices related to anemia and supplementation among high school and vocational school students. Data was collected from 52 students in Ciamis, using secondary data from Empowerment of Weekly Folate-Iron Supplementation Program in High Stunting Areas. Significant differences (p<0.05) were found in weekly consumption of vegetables and fruit. High school students had higher average frequencies of iron-rich and iron-inhibiting food consumption, although not statistically significant (p>0.05). Both groups had inadequate intake of energy, protein, vitamins A, C, B12, folate and iron. Knowledge scores were higher among high school students, but not significantly different (p=0.778). Attitude scores were almost similar and positive in both groups. Vocational school students showed better compliance with a higher average number of tablet consumptionand statistically significantly different (p=0.01) from high school students. Hemoglobin levels were higher in high school students, but not significantly different (p>0.05). No significant correlation was found between energy, protein, vitamins A, C, B12, folate, iron intake, knowledge, attitude, and the number of IFA tablets towards anemia status (p>0.05)., Adolescent girls are at high risk of anemia due to unmet nutritional needs and low compliance to the government's folate-iron supplementation program.

Judul: Karakteristik Komponen Kayu Bagian Lunas, Gading-gading, dan Linggi pada Kapal Kayu di Teluk Nara, Lombok Utara
Abstrak: Kapal SV Vivian merupakan kapal pariwisata yang terbuat dari kayu solid. Kapal SV Vivian terdiri dari bagian lunas, linggi haluan dan linggi buritan, gading-gading, wrang, galar kim, galar balok, balok geladak dan lutut-lutut, kulit luar, geladak, pagar, sekat kedap air. Pembuatan kapal hanya didasarkan pada pengalaman, sehingga perlu diteliti untuk mengetahui karakteristik komponen kayu yang digunakan. Penelitian mengukur karakteristik atau sifat-sifat dasar komponen kayu yang digunakan pada bagian gading-gading, linggi dan lunas. Standar pengujian yang digunakan yaitu BS-373: 1957. Jenis kayu yang digunakan untuk pembuatan lunas dan linggi yaitu kayu Ulin (Eusideroxylon zwageri) dan gading-gading menggunkan kayu kempas (Koompasia malacensis). Kayu ulin memiliki karakteristik yang lebih baik dibandingkan dengan kayu kempas. Kayu ulin masuk kedalam kelas kuat I dan tahan terhadap serangan marine borers sehingga tergolong kedalam kelas awet I. Kempas tergolong kedalam kayu dengan kelas kuat II dan ketahanan terhadap marine borers masuk kedalam kelas awet V. Bagian lunas kapal disambung dengan menggunakan baut dan jenis sambungan yang digunakan yaitu plain scarf.
