Judul: Analisis Keragaman Konsumsi Pangan Rumah Tangga Penerima Program Diversifikasi Pangan di Kabupaten Bogor
Abstrak: Metode sederhana dalam penilaian keragaman konsumsi pangan rumah tangga adalah Household Dietary Diversity Score (HDDS). Penelitian ini bertujuan untuk menganalisis keragaman konsumsi pangan rumah tangga penerima program diversifikasi pangan di Kabupaten Bogor. Desain penelitian yang digunakan adalah cross-sectional, penelitian ini menggunakan sebagian data baseline penelitian “Validasi Metode HDDS Modifikasi pada Rumah Tangga Penerima Program Diversifikasi Pangan di Kabupaten Bogor” (Baliwati et al. 2014). Subjek penelitian berjumlah 60 rumah tangga yang berada di Desa Citayam dan Babakan. Hasil analisis korelasi menunjukan bahwa HDDS berhubungan signifikan dengan pendidikan kepala rumah tangga (p<0.01), pendidikan istri (p<0.05), usia istri (p<0.05) dan pengetahuan gizi istri (p<0.05).

Abstrak: Household dietary diversity can be measured using Desirable Dietary Pattern (DDP), Household Dietary Diversity Score (HDDS), and modified HDDS. The general objective of this research is to compare several methods for assessing household dietary diversity. The specific objectives of this research were to identify characteristics of households, household food expenditure, and household dietary diversity; analyze correlation between household food expenditure and characteristics of households; and analyze correlation between household food expenditure and household dietary diversity based on DDP, HDDS, and modified HDDS. This research was cross-sectional study and used 118 households in Citayam and Babakan Village. This research was a part of research project “Validation of Modified HDDS (Household Dietary Diversity Score) for Recipient Household of Food Diversification Program in Bogor District” that was leaded by Dr Ir Yayuk Farida Baliwati, MS. Almost households in Citayam and Babakan Village was categorized as small household (59.32%). Fathers and mothers had low education level (36.44%, 44.92%). Fathers and mothers were categorized as middle adult (58.48%, 64.41%). Almost fathers worked as trader (25.42%) while mothers worked as housewife (73.73%). Almost households had high food expenditure level (50.85%). Household dietary diversity was high based on HDDS (95.76%) and modified HDDS (81.35%) but very low based on DDP (50.85%). Spearman correlation test showed that there were positive correlation between household food expenditure with education level of fathers (p=0.022 r=0.210), mothers (p=0.010 r=0.236), and total household members (p=0.003 r=0.275). Household food expenditure had positive correlation with household dietary diversity based on DDP (p=0.006 r=0.250) and HDDS (p=0.008 r=0.242). But household food expenditure didn’t correlate with household dietary diversity based on modified HDDS. Variation of dietary diversity based on DDP just could be determined by food expenditure about 3.9% (p=0.018 r2=0.039) but variation of dietary diversity based on HDDS could not be determined by food expenditure (p=0.061 r2=0.022). So, there was no recommendation method for assessing household dietary diversity.

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.
