Judul: Visualisasi Persebaran Masjid di Indonesia Menggunakan CartoDB.
Abstrak: Persebaran masjid di Indonesia membutuhkan standar perencanaan dan kriteria dalam pembangunannya. Salah satu cara melihat persebaran masjid di Indonesia adalah memvisualisasikan persebaran masjid di seluruh wilayah Indonesia. Visualisasi persebaran masjid tersebut dianalisis pola persebarannya untuk melihat bagaimana persebaran masjid pada suatu wilayah. Visualisasi persebaran masjid dan pola persebarannya dikembangkan dengan sistem berbasis web. Pengembangan sistem tersebut menggunakan adaptasi dari metode Waterfall. Pola persebaran masjid dianalisis dengan metode buffer zone method. Penelitian ini bertujuan untuk membuat visualisasi peta pola persebaran masjid di Indonesia dengan melihat persentase wilayah yang tertutup radius masjid dan wilayah yang tidak tertutup radius masjid. Hasil persentase untuk wilayah yang tertutup radius masjid dan wilayah yang tidak tertutup radius masjid pada Kota Bogor menunjukkan bahwa persentase untuk wilayah yang tidak tertutup radius masjid lebih besar daripada persentase wilayah yang tertutup radius masjid. Persentase pada Kota Bogor untuk wilayah yang tidak tertutup radius masjid sebanyak 99.982% dan persentase untuk wilayah yang tertutup radius masjid sebanyak 0.018%.

Judul: Sistem Informasi Geografis Pendidikan dan Kependudukan Kota Bogor Menggunakan Framework Pmapper
Abstrak: In the year of 2004, Regional Socio-Economic Survey has mentioned Bogor as the 12th densely populated city in Indonesia. As the population increased, it needs to be balanced with a good education system. Bogor City Local Government in cooperation with the Badan Pengkajian dan Penerapan Teknologi (BPPT) paid great attention to the development of human resources. Application Geographic information systems can be applied to assist in the process of government monitoring on the quality of education and conditions of the population within the scope of a particular region. In 2009, Aini has developed Geographic Information System for Bogor City Facilities. In this case, spatial data from Aini (2009) can be applied to support Geographic Information System for Education and Population in Bogor City development. This study aimed to design a web-based application system which its the main function displays the data analysis of population and education of Bogor City in the form of Bogor city map, information tabels, and graphs. The color of result map represents number of school in district area, average score of student final test, and number of population in district level. For future development, the information system is expected to be taken into consideration in policy by the relevant local government. The Geographic Information System for Education and Population in Bogor City is developed on Linux Ubuntu 10.04 platform using MapServer, Pmapper-stable framework, PostgreSQL 8.4, and PostGIS 1.5.

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.
