Judul: Faktor-Faktor Yang Memengaruhi Impor Indonesia Dari Uni Eropa Melalui Moda Transportasi Udara
Abstrak: Selama periode tahun 2005-2011, volume impor Indonesia dari negaranegara Uni Eropa melalui moda transportasi udara memiliki trend yang positif. Namun, di Indonesia masih sedikit yang melalui moda pengangkutan barang melalui transportasi udara dibandingkan dengan jasa pengangkutan penumpang. Hal tersebut terjadi karena kualitas infrasktruktur yang belum memadai sehingga memengaruhi biaya dan waktu dalam melakukan impor. Penelitian ini akan menganalisis faktor-faktor yang memengaruhi impor Indonesia dari negara-negara Uni Eropa melalui moda transportasi udara. Variabel-variabel dalam penelitian ini meliputi variabel ekonomi seperti GDP negara-negara Uni Eropa, GDP Indonesia, nilai tukar riil, jarak ekonomi, serta variabel non-ekonomi seperti kualitas bandara Indonesia, stabilitas politik Indonesia dan efektivitas pemerintahan Indonesia. Hasil estimasi dengan menggunakan pendekatan gravity model menunjukkan bahwa variabel yang secara signifikan berpengaruh positif adalah GDP negaranegara Uni Eropa, GDP Indonesia, nilai tukar riil, jarak ekonomi dan kualitas bandara Indonesia, sedangkan variabel efiktivitas pemerintahan Indonesia berpengaruh negatif secara signifikan.

Judul: Analisis Faktor-faktor yang Memengaruhi Volume Impor Indonesia dari ASEAN+6 melalui Moda Transportasi Laut
Abstrak: During period of 2007-2011, volumes of the Indonesian import were dominated by the raws material/goods from the ASEAN+6 countries carried through sea transport mode. However, Indonesia’s sea transport mode in the international trade were inefficient due to poor port infrastructure and logistics service thus it affect the time and cost to import . This research analyze the factors that influences volumes of the Indonesian import by sea transport mode from the ASEAN+6. The variables used in this research are GDP per capita of ASEAN+6, Indonesia’s GDP per capita, economic distance, real exchange rate, also non-economic variables such as Indonesia’s quality of port, political stability and government effectiveness. The gravity model used in this research shows that the variables of Indonesia’s GDP per capita and Indonesia’s quality of port are significantly having positive influence, while the variables of economic distance, real exchange rate, political stability and government effectiveness are significantly having negative influence.

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.
