Judul: Impact of international trade policy on the Indonesian agroindustry sector performance
Abstrak: Penelitian ini bertujuan menganalisis dampak kebijakan perdagangan internasional terhadap kinerja sektor agroindustri melalui pengembangan model ekonometri ka agroindustri. Model terdiri dari 31 3 persamaan simultan yang dikelompokkan dalam tiga blok. Sektor agroindustri didisagregasi kedalam delapan komoditi ekspor dan tujuh komoditi impor, sedangkan mitra dagang maupun eksportirhmportir dunia lainnya didisagregasi kedalam beberapa negara., This research attempts to analyse the impact of international trade policy on the Indonesian agroindustry sector performance by developing an agroindustry econometric model. The model consists of 313 simultaneous equations represented in the three blocks. Agroindustry sector was disaggregated into eight export commodities and seven import commodities, while the trade partners were disaggregated into several economics.

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.
