Judul: Tingkat Partisipasi Pendengar Dalam Penyelenggaraan Siaran Rri Bogor (Kasus Keluarga Besar Pendengar Setia Pro 1 Rri Bogor)
Abstrak: Radio Republik Indonesia (RRI) merupakan satu-satunya radio yang menyandang nama negara, ditujukan untuk kepentingan seluruh lapisan masyarakat wilayah Negara Kesatuan Republik Indonesia. Adapun salah satu misi dari RRI adalah untuk meningkatkan partisipasi publik dalam proses penyelenggaraan siaran mulai dari tahap perencanaan, pelaksanaan, menikmati hasil, dan evaluasi program siaran. Lembaga Penyiaran Publik RRI Bogor mengudara melalui Programa 1 dan Programa 2 dengan segmentasi berbeda. Penelitian bertujuan untuk melihat hubungan faktor internal dan eksternal dengan tingkat partisipasi pendengar dalam penyelenggaraan siaran RRI khususnya Pro 1 melalui tahap perencanaan, pelaksanaan, menikmati hasil, dan evalusi. Penelitian menggunakan metode survai deskriptif eksplanatif dengan menggunakan pendekatan kuantitatif yang didukung pendekatan kualitatif. Berdasarkan analisis uji korelasi rank Spearman dan Chi Square dengan responden sebanyak 45 orang diperoleh bahwa karakteristik pendengar secara umum tidak memiliki hubungan nyata dengan tingkat partisipasi kecuali pengalaman organisasi, dan pelayanan pengelolaan siaran secara umum memiliki hubungan nyata dengan tingkat partisipasi pendengar kecuali kesesuaian waktu dan penyampaian penyiar.

Judul: Hubungan Karakteristik Internal, Eksternal, dan Persepsi dengan Kepuasan Pendengar terhadap Program Talkshow di Radio RRI Bogor (Kasus Pelanggan PLN dan PDAM yang Mendengarkan RRI Bogor)
Abstrak: Radio Republik Indonesia (RRI) was one of many kind of tools that used in the independence period. RRI in forced in order to play the important role as a Public Broadcasting Institution, in other hand RRI also forced to gives a balance information to the society. The most important role of RRI is to extend the develompent program from the government to the society. One of the RRI’s program is Talkshow with several public institution such as PLN and PDAM. This research was conducted to answer several objectives such as: (1) To indetify the satisfaction level from the audience toward the talkshow program in RRI. (2) To analyze the connection between internal charactersitics and the satisfaction level from the audience toward RRI talkshow (3) to To analyze the connection between external charactersitics and the satisfaction level from the audience toward RRI talkshow. And the last purpose (4) to analyze the connection between the exposureness of RRI and the satisfaction level from the audience toward RRI talkshow. Data was collected using questionnaire and was taken from May – June. This research produced several findings. Finding/result from this research shows that the majority of audience aged between 39 – 52, with majority college level graduate, have been a subscriber PDAM for 8 -12 years and 2 – 11 years for PLN, listening to RRI ranged from 6 to 7 times a week with time of listening less then 130 minutes each listening activity, have a good perception toward the resource person and also the services provided by PLN and PDAM. The finding tells us, majority of audience satisfied with the talkshow program. In the internal characteristics there is a quite strong correlation between the time of subscription and the satisfaction level. Mean while in the there is also a strong correlation between the perception toward the resource person, service from PLN and PDAM with the satisfaction level.

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.
