Judul: Pengaruh kerentanan, perubahan, dan stabilisasi berdasarkan siklus perkembangan keluarga terhadap kualitas hidup lanjut usia
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh karakteristik keluarga, kerentanan, perubahan dalam keluarga, dan stabilisasi terhadap kualitas hidup lanjut usia. Desain penelitian ini adalah retrospektif dan cross sectional. Contoh penelitian berjumlah 34 orang lansia (60-75 tahun) dipilih secara sengaja yang masih memiliki pasangan dan sudah tidak memiliki tanggungan. Penelitian dilakukan di Kecamatan Dramaga dan menggunakan teknik wawancara dengna kuisioner. Pemilihan contoh menggunakan metode purposive. Kualitas hidup dibagi menjadi dua yaitu kualitas hidup subyektif dan obyektif. Kualitas hidup subyektif diukur berdasarkan persepsi terhadap kesehatan fisik, hubungan sosial dan lingkungan sedangkan kualitas hidup obyektif dilihat dari pendapatan, kesehatan, pendidikan, dan kebutuhan dasar. Hasil menunjukkan lebih dari separuh contoh memiliki kualitas hidup total tergolong tinggi. Stabilisasi keluarga, kerentanan, dan perubahan dalam keluarga tergolong rendah. Faktor yang mempengaruhi kualitas hidup lansia adalah lama menikah, usia, dan jumlah anak

Judul: Pengaruh Kerentanan, Perubahan, dan Stabilisasi Berdasarkan Siklus Perkembangan Keluarga Terhadap Kualitas Hidup Lanjut Usia
Abstrak: The research aimed to analyze the effect of family characteristics, vulnerability, family life change, and family stabilization toward the elderly‟s quality of life. This research design is retrospectif and cross sectional. Samples of this research were 34 elderly (60-75 years), who still a spouse, haven‟t had, and used purposively selected. The study was conducted in Dramaga subdistrict and used interviews with questionnaires. Quality of life is divided into two that are subjective and objective. Subjective quality of life is measured by perceptions of physical health, social relationship, and environmental. The objective quality of life measured by income, health, education and basic needs. The results showed more than half of the total sample had a relatively high quality of life. Stabilization of the family, family life changes, and vulnerability was low. Quality of life influenced age, length of married, and number of children.

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.
