Judul: Usia Reproduksi Wanita Suku Tengger, Desa Wonokitri, Provinsi Jawa Timur.
Abstrak: Pubertas adalah masa transisi dari masa kanak-kanak ke masa dewasa yang ditandai oleh perubahan kemampuan dan perkembangan reproduksi. Perubahan paling penting dalam pubertas wanita adalah berkembangnya payudara dan menstruasi pertama. Ada dua komponen utama dalam reproduksi wanita yaitu menstruasi pertama (menarche) dan akhir menstruasi (menopause). Menstruasi pertama (menarche) pada wanita menandai terjadinya pubertas sementara itu menopause adalah suatu keadaan saat sudah tidak adanya ovulasi dan siklus menstruasi dalam kurun waktu lebih dari satu tahun. Bervariasinya angka jangka reproduksi antara wanita di berbagai negara dan etnis menyebabkan perlunya informasi lebih banyak tentang jangka reproduksi dari daerah lainnya. Suku Tengger adalah salah satu suku yang tinggal di sekitar Gunung Bromo, Jawa Timur, Indonesia. Penelitian ini bertujuan untuk mengetahui jangka reproduksi wanita suku Tengger. Data dikumpulkan dari hasil wawancara dengan 141 wanita. Semua data dianalisis dengan menggunakan histogram dalam program R 3.4. Jangka reproduksi diperoleh dari saat usia menarke dan usia menopause. Jangka reproduksi wanita suku Tengger adalah 35,9 tahun. Usia rata-rata saat menarke adalah 13,61 tahun. Sedangkan rata-rata usia menopause alami adalah 49,51 tahun.

Judul: Jangka Reproduksi Wanita Suku Baduy, Kabupaten Lebak, Provinsi Banten
Abstrak: Humans grow and develop into a child, adolescent, adult, and aging. Condition who switch from the children phase to teen or young adult phase is called puberty. First menstruation (menarche) in women marking the occurrence of puberty. The women reproductive phase begin with menarche and end at the time of menopause. Menopause is a condition which there is no ovulation and the menstrual cycle. The lead time from puberty until menopause is called the reproductive period of women. Knowing the reproductive period of women is very close with to the nature of women to become pregnant. Baduy tribe was chosen as the comparative with previous studies. Due to, they live outside of alienating themselves from society, the marriage happens his fellow man, not getting an education, and still maintain customs. This study used longitudinal method, the status quo method, and memory method. Data was collected from interviews. The data was processed using the Probit GLM (Generalized Linear Models) in R program. The result showed that menopausal age was 48.64 years, menarche age was 14.97 years (year 1976). The reproductive period was limited by the age of menarche and menopause obtained for 33.67 years.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
