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: Faktor-Faktor yang Memengaruhi Permintaan Transportasi Umum di Kota Bogor.
Abstrak: Perkembangan Kota Bogor dari tahun ke tahun menunjukkan perubahan yang cukup signifikan baik dari aspek pemetaan kota, pembangunan sektor-sektor jasa bahkan pertumbuhan penduduknya. Permasalahan utama terkait dengan sistem transportasi di Kota Bogor adalah kemacetan yang diakibatkan oleh banyaknya jumlah kendaraan. Pada tahun 2013 terdapat rasio yang menunjukkan angka 1:41, artinya bahwa setiap jalan 1 Km dapat diakses oleh 41 kendaraan. Tujuan dari penelitian ini yaitu untuk mengetahui implikasi kebijakan pelayanan jasa transportasi umum di Kota Bogor dengan menggunakan metode regresi logistik. Penelitian ini menggunakan data primer hasil survey terhadap 585 responden dari 6 kecamatan di Bogor. Variabel dependen yang digunakan yaitu penggunaan transportasi dan variabel independennya yaitu jenis kelamin, pendapatan, jarak ke terminal, durasi, biaya, dan jumlah trip. Hasil penelitian menunjukan bahwa jenis kelamin, pendapatan, dan jarak ke terminal berpengaruh signifikan terhadap permintan transportasi umum di Bogor, dengan tingkat kepercayaan sebesar 90%. Saran penelitian ini yaitu pemerintah Kota Bogor segera memberi layanan transportasi umum yang meningkatkan minat masyarakat Kota Bogor agar menyediakan lebih banyak terminal atau tempat pemberhentian resmi.

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.
