Judul: Faktor-faktor yang berhubungan dengan persiapan menyusui pada kehamilan remaja di pedesaan
Abstrak: Tujuannya adalah untuk menganalisis faktor-faktor yang berhubungan dengan persiapan menyusui kehamilan remaja di daerah pedesaan. Desain penelitian ini adalah cross-sectional Penelitian, jumlah sampel sebanyak 42 orang yang berasal dari Kecamatan Dramaga. Data dikumpulkan dengan wawancara menggunakan kuesioner. Hasilnya menunjukkan bahwa 4 dari 10 remaja hamil masih kurang dalam persiapan menyusui khususnya pada ibu hamil perawatan payudara. Hasil uji korelasi Rank Spearman menunjukkan bahwa korelasi negatif signifikan antara pendapatan perkapita dan dukungan keluarga (p<0,05). Pelayanan kesehatan berhubungan positif signifikan dengan dukungan keluarga (p<0,01) dan berhubungan negatif signifikan dengan pendidikan ibu (p<0,05). Pengetahuan tentang gizi, dukungan keluarga, kepercayaan budaya, dan pelayanan kesehatan tidak berhubungan dengan persiapan menyusui (p>0,05). Persiapan menyusui berhubungan negatif signifikan dengan pendidikan ibu (p<0,05) dan signifikan positif berhubungan dengan usia kehamilan (p<0,01).

Judul: Pengetahuan, Sikap, Dan Praktek Pemberian Asi Serta Status Gizi Bayi Usia 4-12 Bulan Di Perdesaan Dan Perkotaan
Abstrak: Exclusive breastfeeding rates in Indonesia is still low. Some studies indicated that low mothers' nutritional knowledge and attitude is the cause of low exclusive breastfeeding practice. The main aim of this study was to compare breastfeeding knowledge, attitude, practice and infants nutritional status between rural and urban areas. In this cross-sectional study, Desa Jayabakti, Kabupaten Sukabumi represents rural area, while Kelurahan Kedung Jaya, Kota Bogor represents urban area. Samples were 31 mothers-infants in each area who were selected by simple cluster sampling method. The differences between two areas were analyzed with the independent t-test, chi-square test, and Fisher's exact test. The correlation between variables were analyzed with rank Spearman. The result of this study showed that mother's knowledge and attitude of nutrition, especially about exclusive breastfeeding, was higher in urban than in rural area. There were differences in mothers' knowledge and attitude between rural and urban areas (p<0.05). Exclusive breastfeeding in rural area practiced by 41.9%, which is higher than in urban area (25.8%). Nevertheless, there was no statistical difference in exclusive breastfeeding practice between rural and urban areas (p>0.05). Breastfeeding practices which statistically difference in rural and urban areas were the introduction of colostrum status and brastfeeding time (p<0.05). Early initiation of breastfeeding was associated with exclusive berastfeeding practice in urban area (p<0.05), but none of the variables were associated with exclusive breastfeeding practice in rural area (p>0.05). Furthermore, exclusive breastfeeding practice was not associated with 4-12 months infants nutritional status (p>0.05). Mothers' family should be targeted as target of audience in breastfeeding promotion.

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.
