Judul: Pengaruh Interaksi Keluarga dan Pengambilan Keputusan terhadap Kualitas Perkawinan pada Keluarga dengan Suami Perantau
Abstrak: Penelitian ini bertujuan untuk menganalisis pengaruh karakteristik keluarga, interaksi keluarga, dan pengambilan keputusan terhadap kualitas perkawinan pada keluarga dengan suami perantau. Penelitian ini menggunakan desain cross sectional study dan melibatkan 60 istri yang memiliki suami merantau dan mempunyai anak usia remaja (12-18 tahun) di Desa Banyuresmi, Kecamatan Banyuresmi, Garut yang dipilih secara purposive. Pengumpulan data dilakukan melalui wawancara dengan bantuan kuesioner. Hasil penelitian menunjukkan bahwa pendapatan keluarga serta interaksi suami dan istri berpengaruh positif signifikan terhadap kualitas perkawinan. sedangkan pengambilan keputusan tidak berpengaruh signifikan terhadap kualitas perkawinan.

Judul: Enzymatic Fuel Cell (EFC) used carbon-polyaniline nanoparticle composite bioanoda with amobolized Glucose Oxidase (GOD).
Abstrak: Polyaniline nanoparticles is one of the conductive polymer which used as a matrix in the manufacture bioanoda in biofuell cell applications. Polyaniline was synthesized by the interfacial polymerization method interfacial two-phase system of organic solvent or water. Products such as polyaniline precipitate was collected and purified by filtrating. The powder was characterized by SEM for morphology structure analyzing of polyaniline surface porous, the analyzing result of particle size was 60 nm. Characterization of TEM showed the thinnest layer of the sample, the morphologically formed groups or aggregations such as fiber to the size of the average particle diameter of 60-80 nm. The crystallinity of X-ray diffraction results showed partial or semi-crystalline structure of polyaniline with an average crystal size was 10.4 nm. Generally, the diffraction pattern indicates that extends sequence crystallinity of polyaniline nanocrystal structure. FTIR analysis indicated that the sample obtained was a conductive polyaniline forms or emeraldine salt (ES). Polyaniline addition on carbon paste electrode observed in voltammogram curve. The oxidation peak in potential 0,4 and 0,6 V, and the reduction peak was seen at -0,1 and 0,8, although it does not look so sharp. The using of glucose oxidase enzyme in solution is less economical, because the enzyme can not be used repeatedly. For using efficiently of enzymes in analyzing and production process, the enzyme immobilization technique was developed. Immobilization of enzymes were applied to produce electron. Polyaniline (PANI nanoparticles) with nanoscale structures with small particle size which had a large surface area, used as a matrix be able to bind the enzyme free and able to maintain the stability of the catalytic activity of the enzyme better. It can be used as an electrode material for anode reaction process on the EFC. Enzymatic fuel cell is an electrochemical technology converted chemical energy into electricity. The driving force is called enzymatic fuel cells are from glucose oxidase enzyme as a bio-catalyst. It also has a high specificity for glucose substrate. The observation result by lower concentration of glucose (0.25 M) produced higher current (5,05 μA). Increasing of glucose concentration( 0,50 M; 0,75M; 1 M) decresed of current results (2,45 μA; 1,69 μA; 1,35 μA). The same thing happens on observations of potential, with a low glucose concentration (0.25 M) produces a high voltage value of 60.8 mV, but decrease voltage value (20.3 mV; 20.8 mV; 15.4 mV) with increasing concentrations of glucose (0.50 M, 0.75 M, 1 M) The value obtained maximum power density was 0.39 μW/cm2 at low glucose concentrations (0,25 M) with increasing concentrations of glucose (0.50 M, 0.75 M, 1 M) decresed the value of the power density (0.071 μW/cm2, 0.044 μW/cm2, 0.026 μW/cm2). The glucose with lower concentration can produced maximum electrical by current, voltage and power density. The values obtained maximum power density was 0.39 μW/cm2.
