Judul: Correlation between Individual characteristics and communication activities among young and adult addicts, with their healing motivations
Abstrak: The research was conducted on February - May 2002 at Rumah Perawatan Ketergantungan Narkotik (Rumwattik) Pamardisiwi Jakarta to study the correlation between individual characteristics and communication activities among young and adult addicts, with their healing motivations. Prior to this research a preliminay study was conducted, to 10 addicted patients at Instalasi Napza Rumah Sakit Jiwa Marzuki Mahdi Bogor resulted in a score of 0,8765.

Judul: Evaluasi Proyek Rehabilitasi Sosial Mantan Pecandu Narkotika, Psikotropika dan Zat Adiktif ( Kasus Panti Rehabilitasi Sosial Pamardi Putra " Galih Pakuan" Kecamatan Parung, Kabupaten Bogor, Propinsi Jawa Barat)
Abstrak: Penyalahgunaan Narkotika, Psikotropika dan Zat Adiktif (NAPZA) di Indonesia telah sampai pada tahap yang memprihatinkan. Dengan jumlah penyalahguna sebanyak 1,3 juta orang, dampaknya tidak hanya kepada individu penyalahguna NAPZA tetapi membawa pengaruh juga kepada keluarga dan masyarakat secara luas. Penelitian yang dilaksanakan di Panti Rehabilitasi Sosial Korban Narkotika (PRSKN) Pamardi Putra "Galih Pakuan" ini bertujuan untuk mengkaji proses rehabilitasi sosial dan mengevaluasi keberhasilan proyek rehabilitasi dalam mengembalikan fungsi sosial para mantan pecandu NAPZA. Penelitian ini dilaksanakan dengan mengkombinasikan metode penelitian kuantitatif dan kualitatif. Metode penelitian kuantitatif berupa sensus untuk mengevaluasi proses rehabilitasi sosial yang dilaksanakan di panti. Metode penelitian kualitatif berupa kegiatan non survei untuk melakukan kajian kasus mereka yang pulang dari panti. Responden penelitian ini berjumlah 90 orang, mereka yang sedang mengikuti kegiatan panti, sedangkan kegiatan yang menggambarkan proses kepulangan peserta rehabilitasi dari panti ada enam orang. Selain kegiatan survei dan non survei, penelitian ini menggunakan data sekunder berupa berkas-berkas hasil kegiatan, buku-buku panduan dan data dari Departemen Sosial yang digunakan untuk memperjelas kajian penelitian.

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.
