Abstrak: Elderly is the last phase of human life cycle, in this phase occurred many changes physically and mentally (Soejono et al. 2000). Breakfast and exercise can contribute energy to increase heart and lung endurance. The study aimed to identify breakfast habits, nutritional status, health status and heart and lung endurance of the participants of elderly exercises activity in Bogor. Cross sectional study was applied in this study. A total number of 30 elderly exercises activity in Lembaga Lanjut Usia Indonesia (LLI), Bogor was actively participated in this study. The study showed that 66.7% elderly always do breakfast. In terms of nutritional status of both groups (male and female), 60.0% belongs to normal category, obese 36.7% and underweight 3.3%. The health status between male and female elderly are considered high but the female’s medium heart and lung endurance status is much higher than the male respondents. Statistical analysis by Spearman correlation test showed that there was no significant relationship exist between breakfast habits with nutritional status, breakfast habits with heart and lung endurance, and health status with heart and lung endurance (p>0.05), but nutritional status with heart and lung endurance showed significant relationship (p<0.05).

Abstrak: The objective of this study was to learn and to analyze food consumption, physical activity, nutritional status and health status of the elderly in Panti Sosial Tresna Werdha Salam Sejahtera Bogor. The design of this study used cross sectional study. The number of samples obtained as many as 32 elderly. The results showed that the sufficiency level of energy was normal category, protein was in high category, vitamin A and C were in sufficient category and then Ca and Fe classified as defficient category. The nutritional status of most male sampels was obese-I while female was normal. Most of the sampels physical activities classified as mild. Most diseases for the past 6-12 months on male samples were diabetes melitus and hypertension on female samples. Most of either male or female samples had a lower morbidity score with high health status. The result of Pearson correlation test showed that the energy and nutrients intake had no significant relationship with nutritional status and health status (p >0.05) either nor between physical activity with nutritional status and health status, and nutritional status with health status (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.
