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: 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.
