Judul: Pola Asuh Makan, Kualitas Konsumsi Protein, dan Perkembangan Kognitif Anak Usia Prasekolah
Abstrak: Anak usia prasekolah perlu mendapatkan perhatian khusus karena pada masa ini perkembangan dan pertumbuhan fisik anak berjalan dengan cepat. Penelitian ini bertujuan menganalisis hubungan pola asuh makan, kualitas konsumsi protein, dan perkembangan kognitif anak usia prasekolah di Desa Pangandaran, Kabupaten Pangandaran, Jawa Barat. Desain penelitian adalah cross sectional study. Contoh yang diamati sebanyak 50 anak yang terdiri atas 12 anak dari keluarga nelayan dan 38 anak dari keluarga non nelayan. Sebagian besar contoh dalam penelitian ini memiliki status gizi normal berdasarkan indeks berat badan menurut umur (BB/U), tinggi badan menurut umur (TB/U), dan berat badan menurut tinggi badan (BB/TB). Pola asuh lingkungan pada anak dari keluarga nelayan dan anak dari keluarga non nelayan tidak memiliki perbedaan yang signifikan. Terdapat perbedaan signifikan antara perkembangan kognitif anak dari keluarga nelayan dan anak dari keluarga non nelayan (p<0.05). Faktor yang berhubungan dengan perkembangan kognitif anak meliputi status gizi berdasarkan indeks TB/U (p<0.05) dan subskala stimulasi akademik pada pola asuh lingkungan (instrumen HOME) (p<0.01).

Judul: Pola asuh makan, stimulasi psikososial, dan perkembangan kognitif anak usia pra-sekolah
Abstrak: The needs of the nutrients children aged 2 to 5 years old is increasing because it would be in the rapid growth and their high activities. The objective of this study was to analyze relationship of child eating patterns, psychosocial stimulation, and cognitive development of preschool children at Subang, West Java. Energy and protein intake between normal and stunting child have a positive significant difference (p<0.05). Dietary diversity score and child eating patterns between normal and stunting child was no difference. The stunting child of having KMS is 34.6% and 34.0% child of non-KMS. Psychosocial stimulation between normal and stunting child have a positive significant difference (p<0.05). There are positive significant different between child of PAUD members and non- PAUD members for cognitive development. Factor that relation with nutritional status is dietary diversity score. Meanwhile, factors that relation with cognitive development, includes the participants of child in PAUD and pshycosocial stimulation.

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.
