Judul: Analisis Kebijakan Penggunaan Bahan Bakar Gas (BBG) Terhadap Usaha Angkutan Kota di Kota Bogor
Abstrak: Pemanfaatan BBG kini sudah banyak diaplikasikan di beberapa kota besar di Indonesia salah satunya di Kota Bogor yang menerapkannya pada jasa transportasi yaitu angkutan kota (angkot). Penelitian ini bertujuan untuk mengidentifikasi persepsi usaha angkot terhadap kebijakan penggunaan BBG di Kota Bogor, menganalisis pendapatan usaha angkot yang menerapkan kebijakan tersebut, dan mengidentifikasi respon kebijakan penggunaan BBG di Kota Bogor. Hasil penelitian menunjukan bahwa persepsi alasan penggunaan BBG dalam usaha angkot adalah faktor rendahnya modal yang dikeluarkan dan harga bahan bakar yang murah, namun aksesbilitas untuk menggunakan BBG masih sulit dibandingkan menggunakan BBM. Pendapatan usaha angkot yang menggunakan BBG untuk kendaraannya memiliki keuntungan yang lebih dengan R/C Ratio untuk pengusaha sebesar 3.17 dan supir sebesar 1.52 dibandingkan yang menggunakan BBM dengan R/C Ratio sebesar 2.98 untuk pengusaha dan 1.20 untuk supir. Regresi logistik digunakan untuk menganalisis faktor yang memengaruhi pengusaha angkot dalam memasang converter kit atau menggunakan BBG, didapatkan bahwa jumlah angkot, jumlah tanggungan, jumlah setoran yang diterima, pendapatan perbulan, kepemilikan garasi, modal usaha, dan tingkat pendidikan adalah faktor yang berpengaruh signifikan. Strategi pengelolaan kebijakan yang menggunakan alat analisis SWOT diperoleh yaitu: mengembangkan pembangunan kebijakan dengan bekerjasama dengan investor, meningkatkan sarana dan prasarana yang memadai dengan berkerja sama dengan investor, memperbaiki hubungan internal antara pemangku kebijakan agar implementasinya efektif dan efisien, dan memperbaiki struktur organisasi dalam pengelolaan kebijakan.

Judul: Deskripsi Usaha Angkutan Perkotaan di Kota Bogor
Abstrak: Currently the number of urban transport (commonly called as “angkot”, an abbreviation of “angkutan perkotaan”) in the city of Bogor has reached the maximum number set by the government as many as 3413 units. However, the number of bussiness run on the field is not balanced by the number of passengers of urban transports. There is often seen an “angkot” does not filled by passangers. Though the number of passengers is a benchmark in measuring the benefit of the business. Based on these reasons, it was necessary to conduct a research in order to get insight about the value of financial feasibility as well as descriptions and perceptions of the business subject. The Business feasibility analysis that pointed to the business owners was Net Present Value (NPV) and period of Return on Investment (ROI). Meanwhile, the Regional Minimum Wage (UMR) of City of Bogor was used to assess the feasibility of public transportation drivers income. Data used in this study was the result of survey to the drivers and owners of “angkot”, and also observation to the number of passengers. Mostly the drivers were employees. They feel lucky to undergo a job as a driver, but most of them do not want to continue working in this field. Thi business if urban transport is reasonably to run because the income generated exceeds the UMR of City of Bogor. The Owners were also eligible to continue in conducting the business accorrding NPV and ROI period. In average, the number of passengers just as much as four people in an unit. The amount is less than the half the capacity.

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.
