Judul: Motivasi dan Opini Khalayak Langsung Acara Musik “Derings” Trans TV (Kasus Episode Minggu Ketiga, Bulan Mei 2010)
Abstrak: The objectives of this research are: (1) to describe the direct audiences profile of "Derings", (2) to explain the motivation of direct audiences for watching "Derings" and to identify its influential factors (3) to study about public oppinion of "Derings"’ direct audiences with its influential factors. The research has been conducted at Trans TV station on the third week of May 2010. The selection of location and respondent has been done purposely. The Respondents in this research are direct audiences of "Derings" who watched it on the third week of May 2010. The data has been collected by using questionnaire and in depth interview technique. The data which is collected from questionnaire then analized by Chi-square and Rank Spearman test.The intrinsic factors and extrinsic factors are supposed to be able to describe the characteristics and profile of direct audiences of “Derings”. The results of this research based on the processing data by using Chi-Square and Spearman Rank, showed that several intrinsic factors have tangible correlation with motivation aspects significantly. The respondents have mostly good opinions about the presenters, guest stars, and setting area/ musical stage of "Derings" at Trans TV station, but in the other hand, broadcasting/delivery aspect of this program has been assessed as less than good by them. The extrinsic factors of respondents that have correlation with their oppinion about this program.

Judul: Sintesis Biphasic Calcium Phosphate-High Density Polyethylene Scaffold
Abstrak: Biphasic Calcium Phosphate (BCP) - High Density Polyethylene (HDPE) scaffold has been synthesized by using raw material from the shells of green mussels as a source of calcium to synthesize BCP. The shells are calcined at a temperature of 1000 °C for 5 hours to form a single phase of CaO. Ca(OH)2 is formed through the binding of H2O by CaO. CaO and Ca(OH)2 is reacted with P2O5 through milling process at a speed of 600 rpm for 6 hours and sintering process at a temperature of 900 °C for 3 h. The BCP resulted from these processes is a composition of 47,80% hydroxyapatite (HAp), 44,60% β-tricalcium phosphate (β-TCP) and 7,600% impurity of Ca(OH)2. This composition value is obtained by manual calculated using the direct comparison method based on XRD data. The lattice parameter of HAp is a = 9,436 Å and c = 6,906 Å, and lattice parameter of β-TCP is a = 10,44 Å and c = 37,45 Å. BCP has 1,244 to 2,723 of Ca/P ratio. BCP crystal grains become more homogeneous after sonication process. Milling process is performed on a rotary speed of 1325 rpm for 20 minutes result in a homogeneous BCP in the HDPE matrix. The increasing of sonication time and used BCP will increase scaffold hardness value.
