Judul: Keragaman Konsumsi Pangan dan Hubungannya dengan Status Gizi pada Orang Dewasa di Perkotaan
Abstrak: This study aimed to analyze the diversity of food consumption and the association with nutritional status among adults in urban area especially in DKI Jakarta. This study using a cross sectional design and secondary data. Subject were 102 adults. The data collected were socio economic characteristic (age, education, family size, nutritional status (BMI and waist hip ratio), food consumption (nutrition intake and dietary diversity score) and healthy status. Diversity of food consumption can measured by Dietary Diversity Score methods and the results showed that most of subject has a good food diversity. Spearman correlation test showed that there was a positive relationship (p<0.05) between BMI with healthy status and education with iron consumption. Other variables observed were not significantly related (p>0.05).

Judul: Kualitas Konsumsi Orang Dewasa di Perkotaan dan Pedesaan.
Abstrak: Tujuan penelitian adalah menganalisis perbedaan kualitas konsumsi orang dewasa di daerah perkotaan dan pedesaan. Desain penelitian adalah cross sectional study, melibatkan 87 contoh terdiri dari 43 orang contoh di perkotaan dan 44 orang contoh di pedesaan. Penelitian dilaksanakan di Kelurahan Limus Nunggal, Cibeureum dan Desa Bojong Kembar, Cikembar keduanya berada di Sukabumi. Data yang dikumpulkan adalah karakteristik individu, kualitas konsumsi, pengetahuan gizi, dan status kesehatan dengan wawancara menggunakan kuisioner, sedangkan status gizi dan lemak tubuh didapat dengan pengukuran langsung tinggi badan, berat badan, lemak tubuh total, dan lemak viseral. Kualitas diet diukur menggunakan Healthy Eating Index (HEI). Terdapat perbedaan signifikan pengetahuan gizi, status gizi, lemak tubuh total, tingkat kecukupan energi dan lemak antara masyarakat perkotaan dan masyarakat pedesaan, namun tidak terdapat perbedaan lemak viseral, status kesehatan, tingkat kecukupan protein dan karbohidrat, serta skor HEI. Skor pengetahuan gizi contoh di perkotaan lebih baik dibandingkan dengan contoh di pedesaan. Status gizi, persen lemak tubuh, dan lemak viseral lebih baik di pedesaan karena contoh dengan kategori baik atau sehat paling banyak terdapat dipedesaan. Tingkat kecukupan energi dan zat gizi lebih besar di perkotaan dibandingkan dengan contoh di pedesaan. Tidak terdapat hubungan antara kualitas konsumsi dengan pengetahuan gizi, status gizi, persen lemak tubuh, lemak viseral, dan status kesehatan.

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.
