Judul: Persepsi dan minat pemuda terhadap usaha peternakan domba (kasus pemuda desa Neglasari kecamatan Dramaga kabupaten Bogor)
Abstrak: Livestock sector is important especially when Indonesian nation face various crisis of endless economics because it helps to overcome this problem. Livestock sector is not only without problem, a lot of matter influence this sector to be an important sector in development. One of them is shifting job opportunity work in livestock sector. Friction of opportunity work in livestock sector at least influences perception and young men interest, one of them is effort sheep ranch. This research was done in village of Neglasari sub district od Dramaga at April 7th May 7th 2007. Design of this research is Descriptive of Correlation by 50 sponders taken in the Census.

Judul: Studi dampak sosial ekonomi kegiatan pengembangan ternak domba : Program pengembangan masyarakat lingkar pesantren, P. P. Darul Fallah, Kecamatan Ciampea, Kabupaten Bogor
Abstrak: Tujuan penelitian ini adalah : (1) mendeskripsikan bentuk peternakan domba rakyat, (2) menelaah partisipasi peserta dalam kegiatan Pengembangan ternak Domba (PTD), (3) menganalisis dampak sosial ekonomi kegiatan PTD, dan (4) menelaah pengaruh partisipasi peserta terhadap dampak sosial ekonomi kegiatan PTD. Data yang digunakan dalam penelitian ini meliputi data primer yang diperoleh dari wawancara dengan mempergunakan kuesioner dan pengamatan langsung di lapang, serta data sekunder yang diperoleh dari instansi-instansi terkait. Pengolahan dan analisis data dilakukan dengan mempergunakan metode secara kuantitatif dan kualitatif. Data kuantitatif dianalisis dengan mempergunakan tabulasi silang, uji statistik non parametrik dengan metode korelasi Rank Spearman dan disajikan secara deskriptif. Kegiatan PTD ini merupakan salah satu kegiatan dari program Pengembangan Masyarakat Lingkar Pesantren (PMLP), P.P. Darul Fallah. Tujuan dari kegiatan PTD ini adalah agar peserta dapat mengembangbiakkan domba untuk dapat meningkatkan pendapatan keluarga. Sasarannya adalah warga yang tingkat sosial ekonominya rendah. ...

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.
