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: 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.
