Judul: Analisis Dampak Relokasi Pedagang Kakilima (PKl) di Blok G Pasar Tanah Abang Jakarta Pusat (Periode Tahun 2013 – 2014)
Abstrak: A policy to control the street vendor by Jakarta Provincial Government start to become priority. One that has been done is relocating street vendors on the road around Tanah Abang Market to Block G. Now the road around Tanah Abang Market does not have a traffic jam and clean from street vendors, but this relocation also provide impact on revenue of street vendors. In this study the impact of the relocation analyzed with t-paired test, and factors that influence income before and after relocating street vendors were analyzed using multiple linear regression. This study used the primary data from the interview. The results from the analysis showed that after relocation the revenue was decline amounted to 99 persen of revenue before being relocated. This declining revenue is caused by slack of buyers that come to block G. Factors that influence income only turnover. Other factors such as capital, the long effort, the working hours per day, the age of the trader, gender, education, and the cost of daily work does not have an effect on income.

Judul: Dampak Kehadiran Ritel Modern terhadap Profitabilitas Pedagang Pasar Tradisional di Provinsi DKI Jakarta
Abstrak: The aims of this research are to analyze the impact of modern retail on the profitability level of traditional market traders in DKI Jakarta. The research was conducted on the three traditional markets in DKI Jakarta, which are Jembatan Besi Market and Menteng Pulo Market as treatment markets (traditional market which is close to the modern retail), Lenteng Agung Market as control market (traditional markets which is far from modern retail). This research uses t-test, chi-square test and ordinal logistic regression. The existence of modern retail affect the profit of traditional market traders changes in DKI Jakarta. The closer distance the traditional market to the modern retail, the more chance of traditional market traders to decrease their profit

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.
