Background: Stunted overweight is associated with mild chronic inflammation. The state of inflammation will increase the expression of hepcidin, which affects the iron status of the body, besides the intake of protein, iron, and vitamin C.Objective: To analyze the correlation of hepcidin levels and food intake (protein, iron, vitamin C) with serum transferrin receptors (sTfR) and hemoglobin in stunted overweight adolescents.Method: The design of research was cross-sectional. The subjects were 64 adolescents stunted overweight aged 15-18 years in four high/vocational schools in the Banyumanik District, Semarang City. Measurement the level of hepcidin and sTfR was using the ELISA method and haemoglobin was using Cyanomethemoglobin method. Data on protein, iron, vitamin C intake was using the SQ-FFQ method. Bivariate analysis was using Pearson and Spearman correlation test then followed by multiple linear regression analysis.Results: The result showed that 89.1% subjects had adequate intake of protein, 54.7% subjects had low intake of vitamin C, 76.6% subjects had low intake of iron. Hepcidin levels in all subjects were 100% normal. There were 7.8% subjects with a low sTfR and 7.8% with a low haemoglobin level. Statistic test showed there was correlation between hepcidin with haemoglobin and sTfR (p1 = 0,010 r1 = -0,319, p2 = 0,001, r2 = 0,569). From food intake, only intake iron was correlated with haemoglobin but not with sTfR. There was significant difference between the mean of haemoglobin and sTfR among girls and boys. Further analysis, showed that only hepcidin was a weak negative determinant for sTfR (R2 = 0,120). The determinant factors for haemoglobin were gender (p=0,001) and hepcidin (p =0,004) with the value of R2 = 0,577.Conclusion: Hepcidin correlated with sTfR and haemoglobin while iron intake only correlated with hemoglobin.

Background: Salak is one of Maluku's endemic fruits, especially in Buria Village which makes it the main outcome to increase people's income. Salak fruit contains quite complete nutritional elements such as energy, protein, carbohydrates, calcium, phosphate, iron, vitamin B, vitamin C, and water. To reduce the damage of fruit, the fruit of bark is processed into nata that has high nutritional and economic value. Making nata de Salacca assisted by microorganisms namely bacteria Acetobacter xylinum. In this case the microbes play an important role to overhaul substances that are difficult food absorbed by the body into food substances that are easily absorbed by the body. In addition, microbes provide flavor to the processed products. Methods: The duration of fermentation used in this study was 10 and 14 days. To determine the taste of nata de Salacca that has been processed then performed organoleptic test against 15 panelists. Result: The result is a brownish-white color, a slightly acidic sense of conformity, a chewy texture and a slightly acid-scented aroma, so there is a long-standing fermentation effect on the taste of nata de Salacca. Conclusion: The duration of fermentation has an effect on taste of nata de Salacca covering aspect of color, flavor, texture and aroma

Aji SP, Anandito BK, Nurhartadi E. 2013. Study of addition of various types of honey as alternative sweetener in white dragon (Hylocereus undatus) juice drink. Biofarmasi 11: 13-18. Indonesia is a tropical country, so people tend to consume lots of water to refresh the body. Along with the development of technology and the desire of people to come back to healthy life, it is necessary to manufacture beverage that have functional value. Dragon fruit has a large nutritional content. Dragon fruit contains several bioactive components, such as: anthocyanin, vitamin C, beta-carotene and soluble fiber in the form of pectin. Therefore, the processing of dragon fruit into juice that contains bioactive components is potential. In general, fruit juice beverage use a sweetener based on sucrose, therefore in this study it was used honey as an alternative sweetener that has a functional value. This research aimed to study the making of white dragon juice (Hylocereus undatus) using honey sweetener types of rambutan, kelengkeng and randu, and to analyze its chemical characteristic (vitamin C and antioxidant) and sensory properties (taste, color, aftertaste, overall). In this study, it was used white dragon fruit and various types of honey such as randu honey, rambutan honey and kelengkeng honey with the concentrations of 5%, 10% and 15%, respectively. The results showed that dragon fruit juice with the addition of rambutan honey contained vitamin C and antioxidant greater than the addition of randu and kelengkeng honey. The addition of honey with the different concentrations (5%, 10%, 15%) could also increase vitamin C and antioxidant contents in the produced functional beverage. The higher concentration of honey that added, the higher produced vitamin C and antioxidant contents. Meanwhile, the sensory test results of color, taste, aftertaste and overall parameters for dragon fruit juice samples with the addition of rambutan, rambutan and kelengkeng honey, the average of panelists gave a like score. But, the higher concentration of honey that added, the sensory results indicated the panelist preference decreased. According to the results of the panelist study showed the level of fondness in all types of honey at a concentration of 10%.
