Judul: Karakteristik Dan Perkembangan Bahasa Anak Balita Stunted Di Desa Sukawening, Kabupaten Bogor
Abstrak: The high prevalence of stunted children in Indonesia (35.6%), especially in Bogor Regency (37.2%) threaten the quality of human resources in the future. Because stunting as a measure of chronic undernutrition can interfere with child development, one of which is the development of language. The purpose of this study are to identify the characteristic of stunted children and the association between stunted and language development. The study design was a cross-sectional study. Total samples of the study were 30 children consisting of stunted and severe stunted. Almost all children were born with enough birthweight and given breastmilk. But they didn’t receive exclusive breastfeeding in the first six month and most of them are weaned before 2 years-old. The highest percentage level of education of fathers and mothers only primary school and more than half of children came from poor families. The highest percentage of children had low language development. There was no association between stunted and languange development but there was negative association between age and language development.

Abstrak: The problem of protein energy inadequacy is an major problem among underfives that effects of child growth. The prevelance of stunted and severe stunted status among underfives in Indonesia in 2010 based on Height/Age (H/A) Index was 35.6 % (18.5% severe stunted and 17.1% stunted). The purpose of this study to identify the association between nutrition status and language and cognitive development of underfives also differences of language and cognitive development between stunted and normal childern. The study design was a cross-sectional study. Sample size was 70 children consisted of 35 normal and 35 stunted childern. The highest percentage level of education of fathers and mothers only primary school and more than half of children came from poor families. It was show that stunted childern had lower language and cognitive development than normal childern. There was significant difference (p<0.05) of language and cognitive development between normal (non-stunted) childern and stunted. Also there was significant difference (p<0.05) between age of childern, mother level of education and family income with language and cognitive development. Child care practices was no difference between stunted childeren and non-stunted childern. There was a significant association between nutrition status based on Height/Age with language development (p<0.05), but it was no association with cognitive developmentm (p>0.05).

Judul: Pembuatan Film Tipis Cu2ZnSnS4 sebagai Lapisan Penyerap Cahaya pada Sel Surya Menggunakan Metode Elektrodeposisi
Abstrak: Thin film of Cu2ZnSnS4 (CZTS) is an alternative semiconductor used as light absorber layer on solar cell. CZTS can replace silicon that commonly used as commercial semiconductor. The advantage of using CZTS as absorber layer is due to the abundance of its chemical composer on earth, and its high value of absorption coefficient. The absorber layer was made by using electrodeposition method on ITO glass substrates. The films were deposited at room temperature using potentiostatic mode with a potential of –1.05 V for 30, 45, and 60 minutes. After that, the films were annealed at two different temperatures, 180 ºC and 500 °C, for 45 minutes in N2/H2S atmosphere. Based on X-ray diffraction analysis, the polycrystalline thin film obtained fall into kesterite crystal phase. This type of crystal was obtained when the CZTS was annealed at 500 °C in H2S/N2 atmosphere. The value of optical band gap energy for the CZTS thin film was 2.2 eV with the film thickness about 1.228–6.366 μm. The sample of CZTS with electrodeposition time of 45 minutes and annealing temperature of 500 °C showed the best result and in conformity with absorber layers criteria for solar cells.
