Judul: Hubungan Perilaku Menonton Orang Pinggiran di Trans 7 dengan Empati Remaja di Desa Cihideung Ilir Kecamatan Ciampea Bogor
Abstrak: This study aimed to analyze the correlation between internal factors adolescense with viewing behavior, the correlation between external factors adolescense with viewing behavior, and correlation viewing behavior with adolescense empathy. The research sample was adolescense in Cihideung Ilir Village Ciampea District Bogor who had seen the program in “Orang Pinggiran” Trans 7. The results of the study explain that the gender associated with the duration of the watch. Age, level of education, occupation, and television ownership was not associated with viewing behavior. On testing the interaction with family and interaction with friends wasreal associated with viewing behavior. Finally, the viewing behavior of “Orang Pinggiran” Trans 7 was not associated with adolescense empathy.

Judul: Hubungan antara Motivasi Menonton dan Keterdedahan Tayangan Orang Pinggiran Trans7 dengan Sikap Prososial Remaja di Pedesaan
Abstrak: Televisi kini telah mampu menjangkau khalayak luas, termasuk masyarakat pedesaan. Penelitian ini bertujuan untuk menganalisis hubungan antara karakteristik remaja di pedesaan dengan motivasi menonton, motivasi menonton dengan keterdedahan program Orang Pinggiran, dan keterdedahan program Orang Pinggiran dengan sikap prososial remaja di pedesaan. Remaja dipilih sebagai unit analisis, sebab masa remaja adalah masa peralihan, ketika individu tumbuh dari masa anak-anak menjadi individu yang memiliki kematangan. Teknik pengumpulan data yang digunakan dalam penelitian ini adalah teknik wawancara dengan menggunakan kuesioner. Hasil penelitian ini menunjukkan bahwa terdapat hubungan antara usia, jenis kelamin, pendidikan terakhir, jenis pekerjaan, tingkat interaksi dengan keluarga, dan tingkat interaksi dengan teman dengan motivasi menonton program Orang Pinggiran dan antara motivasi menonton dengan keterdedahan tayangan tersebut. Selain itu, keterdedahan program Orang Pinggiran berhubungan dengan sikap prososial remaja dalam aspek kognitif dan afektif.

Judul: Synthesis of Apatite - Chitosan Composite Using Duck Eggshell and Chitosan with Temperature and pH Control
Abstrak: Composite of apatite-chitosan was prepared by using chitosan as polymer matrix. Calcium phosphate was prepared from CaO and (NH4)2HPO4, which the ratio Ca : P had to be 1.67. Chitosan is produced by deacetilase from biopolymer chitin. Duck eggshell (95% CaCO3) as starting material was converted to be calcium oxide (CaO) through calcinations with temperature 1000oC for 5 hours. In-situ and ex-situ methods were prepared from apatite and chitosan (dissolved with acetate acid 2%). Calcium phosphate prepared for bone implantation, but it is too fragile and brittle to be implant into the body. So addition of chitosan can decrease crystalinity and increase mechanic characteristic (tougher). Composite apatite-chitosan was resulted by fast precipitation. Fast precipitation was held in a breaker glass with nitrogen atmosphere, under controlled temperature at 37oC and pH 7, in order to increase amount of hydroxyapatite. Precipitation with CaO which was dropped by (NH4)2HPO4. Hydroxyapatite and chitosan were appearing at samples with in-situ and ex-situ methods which indicating by peak matching of XRD (closed lattice parameter, crystal size), overlapping at FTIR spectra and supporting by SEM picture (homogenous and agglomerated particle). However, it still needs further research to examine biocompatibility osteoconductive degree of sample by in-vivo and in-vitro test.
