Judul: Peran Ganda, Curahan Waktu Kerja, dan Kontribusi Ekonomi Istri pada Keluarga Petani
Abstrak: The aim of this research to identify and analyze double burden, time allocation for work, and the contribution of wife to farmer families income. This research was using Descriptive analysis and Pearson correlation. Sample were working wife who comes from farmers families, which was performed among 70 working wife in Desa Ciaruten Ilir, Kabupaten Bogor, in April-Mei 2013. The results showed that almost all wife (90%) have double burden in the high category. Another results showed almost wife (92.9%) dominate domestic sector roles, and almost quarter (72.9%) wife can coordinate roles in public sector with husband. A time allocation wife for work have an average of 6 hours 6 minutes in daily, and the contribution of wife to the family income by 33.54 percent monthly. There are a positive significant relationship between time allocatin for working wife and the economic contribution of wife, and significant relationship between economic contribution of wife and family income. Regression test showing 41.0 percent research variable influence economic contribution of wife. Husband income give significant influence to economic contribution of wife.

Judul: The Role of Women in Increasing Household Income of Rice Farmers in Dry Land (Case Study: Mekarjaya Village, Ciemas Subdistrict, Sukabumi Regency)
Abstrak: Kondisi ekonomi keluarga petani pedesaan yang serba kekurangan menyebabkan perempuan memiliki peran ganda yaitu sebagai ibu rumahtangga sekaligus pencari nafkah baik dari kegiatan usahatani maupun non-usahatani. Penelitian ini bertujuan untuk 1) menganalisis peranan perempuan dalam kegiatan usahatani, 2) menganalisis peranan perempuan dalam pengambilan keputusan rumahtangga pada usahatani, 3) menganalisis kontribusi pendapatan perempuan terhadap pendapatan rumahtangga, dan 4) menganalisis faktor-faktor yang memengaruhi curahan waktu kerja dan pendapatan perempuan dalam usahatani dan non-usahatani. Metode analisis data dalam penelitian ini adalah analisis peran gender (analisis Harvard dan skala Likert), analisis kontribusi pendapatan, dan analisis regresi linear berganda dengan metode Ordinary Least Square (OLS). Hasil penelitian ini menunjukkan kegiatan yang umumnya dilakukan oleh perempuan pada kegiatan usahatani meliputi kegiatan penanaman, penyiangan, panen, dan pascapanen. Keputusan rumahtangga yang hanya ditentukan oleh perempuan dalam kegiatan usahatani dominan adalah kegiatan manajemen keuangan usahatani. Rata-rata kontribusi pendapatan perempuan pada rumahtangga yang hanya melakukan kegiatan usahatani di ladang/kebun sebesar 2.394.098 rupiah per tahun, sedangkan pada rumahtangga yang melakukan kegiatan usahatani di ladang/kebun sekaligus sawah sebesar 1.967.954 rupiah per tahun. Faktor yang berpengaruh nyata terhadap curahan waktu kerja perempuan dalam usahatani adalah curahan waktu kerja perempuan dalam non-usahatani, luas lahan, dan jumlah anak balita. Faktor yang berpengaruh nyata terhadap curahan waktu kerja perempuan dalam non-usahatani adalah pendapatan perempuan dalam non-usahatani. Faktor yang berpengaruh nyata terhadap pendapatan perempuan dalam usahatani adalah luas lahan dan curahan waktu kerja perempuan dalam usahatani. Faktor yang berpengaruh nyata terhadap pendapatan perempuan dalam non-usahatani adalah curahan waktu kerja perempuan dalam non-usahatani dan jumlah anak balita., The economic condition of rural farming families that are underprivilage causes women to have a dual role as housewives as well as breadwinners both from farming and non-farming activities. This study aims to 1) analyze the role of women in farming activities, 2) analyze the role of women in making household decisions on farming, 3) analyze the contribution of women's income to household income, and 4) analyze the factors that affect women's work time and income. in farming and non-farming. The data analysis method in this research is gender role analysis (Harvard analysis and Likert scale), income contribution analysis, and multiple linear regression analysis using the Ordinary Least Square (OLS) method. The results of this study indicate that the activities generally carried out by women in farming activities include planting, weeding, harvesting and post-harvest activities. Household decisions that are only determined by women in dominant farming activities are farm financial management activities. The average contribution of women's income to households that only carry out farming activities in the fields/gardens is 2,394,098 rupiah per year, while in households that carry out farming activities in fields/gardens as well as rice fields are 1,967,954 rupiah per year. Factors that significantly influence women's work time in farming are women's working time spent in non-farming activities, land area, and the number of children under five. The factor that significantly influences women's work time in non-farming is women's income in non-farming. Factors that significantly influence women's income in farming are the area of land and the time spent working for women in farming. Factors that significantly influence women's income

Judul: Membran Komposit Kitosan-Nanopartikel Magnetik Fe3O4-Hidroksiapatit untuk Rekayasa Jaringan Tulang.
Abstrak: Composite membrane implants from biodegradable and biocompatible polymers such as chitosan, added with Fe3O4 magnetic nanoparticleshydroxyapatite (MHAP) is an alternative that is appropriate for bone tissue engineering. The MHAP was first synthesized using coprecipitation method with 3 different composition, with the ratio of Fe3O4 : hydroxyapatite is 3:7, 4:6, and 5:5 by mass. The composite membrane chitosan-MHAP (MK K-MHAP) was then synthesized by mixing a chitosan solution and the best MHAP composition (10, 20, 30, and 40% w/w of the mass of chitosan). Characterization using X-ray diffraction confirmed the formation of Fe3O4 and hydroxyapatite phase on the MHAP. The magnetic saturation value and size of Fe3O4 magnetic nanoparticles increase with the increasing Fe3O4 composition in MHAP and MK K-MHAP which characterized based on its magnetic hysteresis and particle size distribution curve, respectively. The morphology of the best composition of MHAP composite was analysed using transmission electron microscope. Molecular interactions in MK K-MHAP was characterized based on infrared spectra. Immersion test of MK K-MHAP showed optimum state at 30% mass MHAP composition in chitosan matrix with calcium concentration released about 1000 ppm within 144 hours.
