Judul: Risk Factors of Stunting Among School-aged Children
Abstrak: Based on the results of Indonesian Basic Health Research in 2010, the national prevalence of stunting among school aged children (6-12 years old) was 35.6%. Stunting is a major public-health problem in low and middle-income countries because of its association with increased risk of mortality during childhood. Stunting also leads to significant physical and functional deficits among survivors (The Lancet 2008). Stunting affects the development of cognitive processes during school-aged period (Kar et al. 2008). Several studies have shown that during school-aged period, children was less experienced catchup growth or remain stable even experienced stunting (Friedman et al. 2005). Health Research and Development Agency of the Indonesian Ministry of Health has conducted a Basic Health Research at national scale in 2010 that could potentially be analyzed to determine the risk factors for stunting in school-aged children. Therefore, the objective of this study was to analyze risk factors of stunting among school-aged children. Specifically, objective of this study as follows: (1) identify the characteristics of the children and families of stunted and normal children, (2) identify health and environmental sanitation in stunted and normal children, (3) identifying the incidence of infectious diseases (malaria) in stunted and normal children, (4) analyzing the quantity and quality of food consumption in stunted and normal children and (5) analyze factors that influence the incidence of stunting in the children. This study used secondary data from Basic Health Research by Health Research and Development Agency of the Indonesian Ministry of Health in 2010 with a cross-sectional study design. The data analyzed in this study were from eight Provinces which selected according category of prevalence of stunting (WHO 1997), were very high (≥ 40%) in East Nusa Tenggara and North Sumatra, high (30-39%) in West Nusa Tenggara and West Java, moderate (20-29%) in Bangka Belitung, Jakarta and Yogyakarta, and low (<20%) in Bali. Processing and data analysis was conducted in June-October 2013. Subjects of this research are boys and girls aged 6-12 years from eight provinces. Number of subjects contained in the electronic files was 11335 children. After a cleaning process, the number of children analyzed was 8710. Analysis data used Microsoft Excel 2007 and SPSS for Windows version 17.0. The t test and oneway ANOVA was used to determine mean difference of variable with data continues and mean HAZ. Chisquare test was used to determine relationship between independent variable with stunting. Multivariate analyzes were performed using logistic regression with Backward Wald method with statistical significance criteria of p<0.05, and the value of the confidence interval (CI) of 95%. Prevalence of stunting in eight provinces was 28.11 % and 11.38% were categorized as severe stunting. Stunted children were higher in older children (10- 12 years), male, mother with short stature (<145 cm), parents with low education levels (≤ primary school), father who smoking, mother with a low BMI and father 6 with normal BMI, children with ≥ 8 family member, low household expenditure (quintiles 1 and 2), and living in rural areas. There were significant relationship between children with older age (10-12 years), male children, low maternal height (<145

Judul: Desain Sistem Transfer Energi Nirkabel Berbasiskan Tesla Coil
Abstrak: Tesla coil merupakan alat yang ditemukan oleh Nikola Tesla yang dapat mentransmisikan daya tanpa kabel dengan memanfaatkan prinsip induksi elektromagnetik. Pada penelitian ini dibuat sebuah prototype Tesla Coil dengan menggunakan transistor C1970 dan receiver menggunakan rangkaian LC. Identifikasi alat meliputi pengaruh daya input transmitter terhadap receiver, bentuk signal yang dipancarkan transmitter, pengaruh jarak transmitter dan receiver, nilai efisiensi serta efek alat terhadap perangkat lain. Hasil pengamatan menunjukkan bahwa semakin besar daya input maka semakin besar daya yang dipancarkan oleh transmitter. Bentuk sinyal yang dipancarkan oleh transmitter berupa gelombang listrik AC sinusoidal dengan frekuensi ~2.9 MHz. Semakin jauh jarak receiver terhadap transmitter maka semakin kecil amplitudo gelombang AC yang diterima oleh receiver, menyebabkan semakin kecil daya yang diterima oleh receiver. Adapun nilai efisiensi terbesar penangkapan daya oleh receiver yaitu sebesar 0.00516 % serta terdapat gangguan pada alat-alat tertentu seperti monitor komputer dan radio.
