Judul: Analysis of Competitiveness, Dynamics, and Determinants of Main Commodity Export Demand from Indonesia to United Kingdom
Abstrak: United Kingdom merupakan negara industri dan maju yang berpotensi menjadi pasar untuk ekspor komoditas unggulan Indonesia. Penelitian ini bertujuan untuk menganalisis daya saing, dinamika, dan determinan penawaran ekspor komoditas unggulan Indonesia ke United Kingdom. Penelitian ini menggunakan metode deskriptif dan kuantitatif dengan analisis RCA, EPD, x-model, dan regresi data panel. Sepuluh komoditas unggulan ekspor yang memiliki RCA tertinggi dianalisis posisi dan pengembangan pasarnya. Sehingga ditemukan hasil ada delapan komoditas yang berada pada posisi falling star dengan pengembangan pasar potensial dan dua komoditas berada pada posisi retreat dengan pengembangan pasar kurang potensial. Hasil estimasi regresi menunjukan bahwa variabel PDB perkapita riil Indonesia, harga ekspor, pertumbuhan populasi Indonesia, dan nilai RCA Indonesia berpengaruh signifikan terhadap nilai ekspor komoditas unggulan Indonesia ke United Kingdom. Sementara itu, PDB perkapita riil United Kingdom, jarak ekonomi dan pertumbuhan populasi United Kingdom tidak berpengaruh signifikan terhadap nilai ekspor komoditas unggulan Indonesia ke United Kingdom., The United Kingdom is an industrial and developed country that has the potential to become a market for Indonesia's leading commodity exports. This study aims to analyze the competitiveness, dynamics, and determinants of main export commodities from Indonesia to United Kingdom. This study used descriptive and quantitative methods with RCA, EPD, x-model, and panel data regression analysis. Ten main export commodities have the highest RCA are analyzed for market position and development. So, eight commodities that were in a falling star position with potential market development and two commodities were in a retreat position with less potential market development. The results of the regression estimates show that real GDP per capita of Indonesia, export prices, population growth of Indonesia, and RCA have a significant effect on the value of Indonesian main export commodities to United Kingdom. Meanwhile, real GDP per capita of United Kingdom, economic distance, and population growth of United Kingdom have no significant effect on the value of Indonesian main export commodities to United Kingdom.

Judul: Analisis Dayasaing dan Faktor-Faktor yang Memengaruhi Permintaan Ekspor Komoditas Unggulan Perkebunan Indonesia di Uni Eropa.
Abstrak: Dayasaing ekspor komoditas merupakan salah satu indikator yang digunakan untuk mengukur kinerja perdagangan suatu negara. Penelitian ini menganalisis dayasaing ekspor tiga komoditas unggulan perkebunan Indonesia yaitu kelapa sawit, karet, dan kelapa (kopra) terhadap enam negara di kawasan Uni Eropa antara lain Jerman, Spanyol, Yunani, Italia, Belanda, dan Romania dengan melihat keunggulan komparatif dan dinamika ekspor beserta faktor-faktor yang memengaruhinya. Periode analisis dari tahun 2010 sampai 2015 dengan metode Releaved Comparative Advantage (RCA), Export Product Dynamics (EPD), dan Gravity Model dengan menggunakan pendekatan regresi panel data melalui E-views 8. Hasil penelitian ini menunjukkan bahwa komoditas unggulan perkebunan Indonesia memiliki keunggulan komparatif dan berdayasaing kuat. Adapun faktorfaktor yang memengaruhi permintaan ekspor adalah jarak ekonomi, GDP riil per kapita negara tujuan, harga ekspor, Real Exchange Rate (RER), dan trade openness dengan hasil yang berbeda-beda pada tiap komoditas.

Judul: Isolasi dan purifikasi inhibitor RNA helikase virus hepatitis C dari bakteriosin bakteri asam laktat S34
Abstrak: Target molecular therapy is one of method to prevent hepatitis C virus which was developed recently. NS3 Helicase/RNA helicase hepatitis C virus inhibition using inhibitory peptide are target in molecular therapy. Bacteriocin are inhibitory peptides which can inhibit hepatitis C virus through inhibition of NS3 helicase. Bacteriocin is a peptide which is produced by lactic acid bacteria. The aim of this research were to isolate and to purify bacteriocin from S34 lactic acid bacteria which has high activity to inhibit RNA helicase of hepatitis C virus. S34 lactic acid bacteria were identified using 16S RNA amplification and DNA sequencing identification of S34 lactic acid bacteria was Lactobacillus plantarum WCFS1. The bacterial growth reached logaritmic phase at 7 hours and stationary phase at 10 hours. Bacteriocin were isolated and purified by ammonium sulphate precipitation with 80% saturation, gel filtration chromatography, and characterization of bacteriocin through molecular weight analysis and measured protein concentration. Bacteriocin from S34 lactic acid bacteria were included in 2nd class bacteriocin, had 64.20 % of inhibition against RNA helicase hepatitis C virus, had molecular weight about 1.7-4.2 kDa, and specific activity in the amount of 2.84 x 106 U/mg.
