Judul: Industri Otomotif Indonesia dalam Rantai Nilai Global (GVC)
Abstrak: Perdagangan internasional berbasis rantai nilai global (GVC) kini telah mendominasi seluruh perdagangan. Industri otomotif merupakan salah satu industri yang melibatkan banyak negara dan manufaktur, mulai dari tahap konsepsi hingga purna jual. Industri otomotif merupakan industri yang potensial sejak masuk ke Indonesia, baik dari dimensi perdagangan maupun tenaga kerja. Dengan menggunakan analisis dekomposisi ekspor bruto serta data ekspor-impor otomotif Indonesia, penelitian ini menganalisis komposisi ekspor-impor, dekomposisi ekspor bruto, dan partisipasi perdagangan GVC industri otomotif Indonesia. Penelitian menggunakan data perdagangan produk industri otomotif (ekspor dan impor) periode 2010 - 2019 dan data Trade in Value Added (TiVA) 2005 dan 2015. Hasil penelitian menunjukan bahwa ekspor-impor Indonesia didominasi oleh produk komponen. Sementara itu konten domestik memiliki pangsa terbesar dalam dekomposisi ekspor bruto industri otomotif Indonesia. Terakhir, partisipasi industri otomotif Indonesia dalam GV C masih menunjukan nilai perdagangan yang relatif rendah. Sebagai tambahan, penelitian ini juga menyertakan gambaran kondisi determinan partisipasi GVC Indonesia.

Judul: Competitiveness and Factors Affecting Indonesia's Automotive Exports to the ASEAN Region
Abstrak: Sektor otomotif merupakan bagian dari sektor industri manufaktur yang berkontribusi besar terhadap GDP Indonesia. Pasar ASEAN merupakan paar yang sangat potensial, namun Indonesia hanya menempati urutan kedua dalam penguasaan pasar perdagangan otomotif di kawasan ini. Tujuan penelitian ini adalah menganalisis posisi daya saing dan faktor-faktor yang memengaruhi ekspor otomotif Indonesia ke kawasan ASEAN. Selanjutnya dalam penelitian ini menggunakan alat analisis Revealed Comparative Advantage (RCA) dan data panel untuk menjawab tujuan-tujuan tesebut. Periode dalam penelitian ini adalah enam tahun (2013-2018) dengan negara tujuan ekspor adalah Brunei Darusallam, Kamboja, Malaysia, Myanmar, Laos, Filipina, Singapura, Thailand dan Vietnam. Hasil analisis menunjukkan bahwa otomotif Indonesia memiliki keunggulan komparatif di negara Brunei Darussalam, Malaysia, Filipina, Laos, Thailand, dan Vietnam sedangkan sisanya memiliki daya saing lemah. Hasil analisis data panel menunjukkan bahwa GDP riil perkapita negara tujuan, pertumbuhan populasi negara tujuan, harga ekspor dan nilai tukar riil berpengaruh signifikan terhadap volume ekspor otomotif Indonesia., The automotive sector is a part of the manufacturing industry sector which contributes greatly to Indonesia's GDP. The ASEAN market is a very potential market, but Indonesia is only takes the second position in the dominance of the automotive market shares in this region. The purpose of this research is to analyze the position of competitiveness and the factors that influence Indonesia's automotive exports to the ASEAN region. Furthermore, in this research using Revealed Comparative Advantage (RCA) analysis tools and panel data to answer these objectives. The period in this study is six years (2013-2018) with the export destination countries being Brunei Darusallam, Cambodia, Malaysia, Myanmar, Laos, Philippines, Singapore, Thailand and Vietnam. The results of the analysis show that Indonesian automotive has a comparative advantage in Brunei Darussalam, Malaysia, the Philippines, Laos, Thailand, and Vietnam while the rest have weak competitiveness. The results of panel data analysis show that the real GDP per capita of the destination country, population growth of the destination country, export prices and real exchange rate have a significant effect on the volume of Indonesia's automotive exports.

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.
