Judul: Evaluasi kerangka penarikan contoh pendaftaran rumah tangga survei perkebunan rakyat dan survei cengkih di Jawa Barat tahun 1991/1992
Abstrak: Mutu data suatu kegiatan statistik seperti sensus dan survei sangat tergantung pada beberapa faktor, antara lain metode penarikan contoh, terampilan petugas, dan keproses pengolahan data. Perencanaan suatu kegiatan statistik membutuhkan suatu kerangka induk (Master Frame) dan ke- rangka penarikan contoh induk (Master Sampling Frame) yang mendasari metode penarikan contoh yang akan digunakan. Pada saat ini Biro Pusat Statistik (BPS) telah membentuk kerangka induk CKID dan kerangka penarikan contoh induk (KCI). KCI digunakan untuk sensus dan survei dengan pendekatan rumahtangga maupun usaha, dengan wilayah pencacahan (wilcah) sebagai satuan penarikan contoh. Wilcah adalah suatu areal di dalam suatu desa/kelurahan yang mempunyai identitas dan memiliki batas yang tetap dan jelas…dst

Judul: Evaluasi hasil pencacahan survey sosial eknomi nasional  1992 Jawa Timur
Abstrak: Dari survei-survei yang dilakukan Biro Pusat Statistik (BPS), Survei Sosial Ekonomi Nasional (SUSENAS) merupakan. survei yang mempunyai cakupan data sosial paling luas. Data yang dikumpulkan antara lain menyangkut bidang-bidang pendidikan, kesehatan/gizi, perumahan/lingkungan hidup, kriminalitas, kegiatan sosial budaya, konsumsi dan pendapatan rumah- tangga, perjalanan wisata, dan pendapat masyarakat mengenai kesejahteraan rumahtangganya. Diantara data tersebut yang dikumpulkan tiap tahun hanya yang tergolong data peubah kor (pokok) yaitu karakteristik demografi dan pendidikan. Selebihnya tergolong ke dalam data peubah modul (sasaran) yang frekuensi pengumpulannya sekitar tiga tahun sekali.

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.
