Abstrak: Indonesia is a developing country, had two nutrition problems,i.e. under nutrition and over nutrition. Overweight in childhood would be a risk factor for degenerative diseases, such as vascular diseases, hypertension and hyperlipidemia in adulthood; discrimination from their peer group; negative body image; depression; and unable to manage social interactions. Based on Riskesdas. 2007, prevalence of overweight of 6-14 years-old children in Indonesia was, 9.5% for males and 6.4% for females. In South Sumatera, the prevalence of overweight and obesity of children aged 6-14 years old was 16 % in males and 11 % in females. The Objective of research is to analyze influencing factors associated with overweight in 6-14 year-old children in South Sumatera. Design of the research was the crossed - sectional. Nutritional status, as independent variable was measured with weight for height. Dependent variables consist of sex, age, father education, status of father occupation, family income, number of family member, eating fruits habit, eating vegetable habit, eating fatty food habit, eating sweetfood habit, energy and protein intake, physical activity, and father’s BMI as independent variables. Data were analysis by SPSS. The results show that prevalence of overweight was 12.7%. There were significant correlation among sex, age, physical activity, eating fruits habit, eating fatty food habit, energy intake, protein intake and father’s BMI with overweight (p<0.05). Determinant factor of overweight the most was physical activity (OR = 1.491).

Judul: Analisis faktor yang berhubungan dengan berat bayi lahir dan pengaruhnya terhadap status gizi anak Usia 6 - 11 bulan di Sumatera:
Abstrak: More than 20 million infants worldwide, representing 16% of all births, are born with low birth weight, 90% of them are in developing countries. Basedon the results of Riskesdas 2007 the prevalence of Low Birth Weight (LBW) in Indonesia was 11,5%. Low birth weight infants generally have slow growth and development. The condition may get worse if they lack energy and nutrient intake, get improper rearing pattern and often suffer from infection. In the long run LBW infants tend to have poor nutrition status and malnutrition. The aim of this study was to analyze factors related to birth weight and their effects on 6 - 11 months old infants nutritional status. This study used Riskesdas data, 2007. The datas collected by surveys method, located in 10 provinces in Sumatra with a total sample of 1.749 households that have 6 - 11 months old infants. The results showed prevalence of low birth weight was 4,7% and nutrition problems in infants of 6 – 11 months were severe under nutrition 4,8%, severe wasting 16% and severe stunting 18,8%. Childrens born with low birthweight are more likely to undernutrition, wasting and stunting compare to children born with normal weight. Factors influencing birth weight are antenatal care, maternal education, maternal age and parity. Factors influencing the infant nutritional status are growth monitoring, birth weight, environmental sanitation, infection diseases, maternal nutritional status, health services utilization, access to health services and household expenditure.

Judul: Elektrodeposisi Film Tipis Semikonduktor Cu2ZnSnS4 (CZTS) pada Substrat Kaca ITO
Abstrak: Semiconductor Cu2ZnSnS4 (CZTS) thin film that can be used as absorber layers on solar cell module was made via electrodeposition method. CZTS thin film was electrodeposited on the surface of a silicate glass coated with a thin layer of indium tin oxide (ITO). Deposition process was done using potentiostatic mode at room temperature with a potential of 1.05 V for 30, 45, and 60 minutes, followed with annealing the film at 2 different temperatures, 500 ºC using furnace and 180 ºC using hot plate, both treatments for 45 minutes in N2/H2S atmosphere. The X-ray difractograms were analyzed using Match 2 program and showed that the CZTS thin films had kesterit crystalline structure, with a low percentage of CZTS phase. The thin film also contained secondary phases such as Cu2S, ZnS, and SnS. The obtained CZTS thin films had a thickness between 1.039 and 1.676 μm. Absorption study showed that the band gap energy of CZTS thin films which was annealed using furnace ranged from 1.50 to 1.52 eV, whereas that annealed using the hot plate was not observed. The band gap energy value showed that CZTS thin films can be used as sunlight absorber layers on solar cell. The formation of CZTS crystal film on this investigation was effectively performed using furnace annealing process at a temperature of 500 ºC with deposition time of 45 minutes.
