Abstrak: This study analyzes house condition, eating habits, nutrition nutritional status and health status of underfive children in Tamansari, Bogor. This research is part of the research entitlet “A Multi-Approach Intervention to Empower and Posyandu Nutritional Program to Combat Malnutrition Problem in Rural Areas” was conducted on February 2012 using cross sectional study design. Sample of this study were 120 mother and underfive children selected by purposive sampling with criterias (1) family who have underfive children (boy and girl 0-60 month), (2) registered as posyandu participant, (3) ready for interviewed. Data used was is primary data including characteristics of the sample and family such as number of family member, family income, age, education, and occupation, underfive children characteristics (gender and age), home conditions, eating habits, nutritional status and health status.Secondary data including overview of location research. The analysis was carried out by Structural Equation Modeling (SEM). Based on SEM analysis, the house condition had significant effect on nutritional status (T-value= 2.533). eating habitshad significant effect on nutritional status(T-value=-2.0798). nutritional status had significant influence to health status (T-value= 8.4189).

Judul: Hubungan Partisipasi Ibu Balita di Posyandu dengan Pengetahuan, Sikap, dan Perilaku Gizi Ibu Balita serta Status Gizi Balita di Kecamatan Tamansari, Kabupaten Bogor
Abstrak: The objective of this research is to examine correlation between mother’s participation in posyandu with knowledge, attitude, behavior and adequacy level of children under-five nutrition in Tamansari, Bogor. This research is part of the research which its title was “a Multi-Approach Intervention to Empower Posyandu Nutrition Program to Combat Malnutrition Problem in Rural Areas” was conducted on February 2012 by using a cross sectional study design. 120 people become sample in this research were selected purposively with sample criteria are (1)have children under-five (male or female 0-60 month), (2)registered as a users of posyandu, (3)ready to be interviewed. The data which used are primary data including characteristic of family and individu sample (big of families, income of families, age, education, and job of sample, characteristic of children underfive (gender and age), mother’s participation in posyandu, knowledge, attitude, behavior of nutrition, food consumption of children under-five, and nutritional status of children under-five. Secondary data including general image of research location. The analysis was carried out with Structural Equation Modeling (SEM). Based on the analysis of SEM, mother’s participation has a significant effect on the level of nutrition knowledge (T-value =-2.59E16). Nutrition knowledge has a significant effect with nutrition attitude (T-value = -3.8323). Nutrition attitude has a significant effect with nutrition behavior (T-value = -3.8323). Nutrition knowledge has a significant effect with nutrition behavior (Tvalue = -3.8323). Nutrition attitude has a significant effect with nutritional status of children (T-value = -3.8323). Nutrition behavior has a significant effect with nutritional status of children (T-value = -5.1027)

Judul: Sulfonated Polystyrene-Nafion Composite Gel Polymer Electrolyte for Dye Sensitized Solar Cells Application with Synthetic Dyes
Abstrak: Dye Sensitized Solar Cell (DSSC) merupakan sel surya generasi ketiga dengan kelebihan mudah difabrikasi, biaya produksinya rendah, ramah lingkungan, serta menghasilkan efisiensi konversi daya yang cukup baik. Sistem DSSC tersusun atas elektrode kerja, zat warna, elektrolit, dan elektrode lawan. Elektrolit yang umum digunakan dalam aplikasi DSSC adalah elektrolit cair yang mengandung iodida/triiodida (I-/I3-). Elektrolit cair memiliki kelemahan mudah menguap, sehingga mengakibatkan kinerja DSSC menjadi menurun. Penelitian ini bertujuan memodifikasi elektrolit cair menjadi gel polimer elektrolit komposit polistirena tersulfonasi-nafion serta membandingkan nilai efisiensi dari penggunaan zat warna merah dan kuning sebagai zat pemeka DSSC. Komposit polistirena tersulfonasi-nafion dibuat dengan lima variasi komposisi 0,00:1,00; 0,25:0,75; 0,50:0.50; 0,75;0,25; 1,00: 0,00. Hasil pengukuran menunjukkan komposisi optimum komposit polistirena tersulfonasi-nafion adalah 0,50:0,50 dengan nilai efisiensi 1,50% untuk zat warna merah dan 1,35% untuk zat warna kuning., Dye Sensitized Solar Cell (DSSC) is a third generation solar cell with the advantages of being fabricated, low production costs, environmentally friendly, and producing a fairly good power conversion efficiency. The DSSC system consists of a working electrode, dyes, electrolyte, and counter electrode. The electrolyte commonly used in DSSC applications is liquid electrolyte containing iodide/triiodide (I-/I3-). The electrolyte has the weakness of being volatile, which causes the performance of the DSSC to decrease. This study aims to modify the liquid electrolyte into a gel polymer electrolyte composite PSS-nafion and compare the efficiency values of red and yellow dyes as DSSC sensitizers. Sulfonated polystirene-nafion composite was made with five composition variations 0,00:1,00; 0,25:0,75; 0,50:0,50; 0,75;0,25; 1,00: 0,00. The measurement results show that the optimal composite composition of PSS-nafion is 0,50:0,50 with an efficiency value of 1,50% for red dyes and 1,35% for yellow dyes.
