Judul: Analysis of Competitiveness and Determinants of Exports of Indonesia's Leading Commodities to the African Region.
Abstrak: Kawasan Afrika merupakan pasar potensial bagi Indonesia. Palm oil & it's fraction, soap, fatty acid, dan uncoated paper adalah komoditas yang memiliki nilai ekspor tertinggi ke Afrika. Studi ini menganalisis daya saing menggunakan RCA, EPD, dan IIT, sementara faktor – faktor penentu ekspor menggunakan model Export Demand Function. Analisis ini dapat digunakan sebagai dasar untuk diversifikasi pasar ekspor dan produk ke wilayah Afrika. Analisis RCA menunjukkan bahwa semua komoditas dalam penelitian ini kompetitif di pasar Afrika karena nilainya lebih tinggi dari satu. Posisi pasar komoditas unggulan Indonesia dengan matriks EPD berada pada posisi yang berbeda – beda. Palm oil & it's fraction pada rising star, soap pada lost opportunity, sementara fatty acid dan uncoated paper pada retreat. Hasil IIT menunjukkan tingkat integrasi yang lemah kecuali palm oil & it's fraction yang tidak memiliki tingkat integrasi. Fungsi permintaan ekspor masing – masing komoditas berpengaruh signifikan terhadap nilai ekspor tahun sebelumnya, GDP riil per kapita, jarak ekonomi, harga ekspor riil, dan nilai tukar riil. Oleh karena itu, Indonesia harus meningkatkan nilai ekspornya ke kawasan Afrika dalam skema kesepakatan perdagangan bilateral.

Judul: Analysis of Indonesian Main Commodities Export Performance to ASEAN + 4 in 2010-2015
Abstrak: Indonesia sudahsejak lama melakukan perdagangan dengan berbagai Negara namun masih terbatas pada komoditas tertentu dan Negara mitra utama seperti Cina, AmerikaSerikat, Jepang, India dan Singapura. Negara yang potensial untuk dijadikan mitra diantaranya adalah negara ASEAN+4. Komoditas unggulan ekspor Indonesia ke ASEAN+4 yaitu fixed vegetable fats and oils (SITC 422), miscellaneous chemical products, n.e.s. (SITC 598), electrical apparatus (SITC 772) serta paper and paper board (SITC 641). Hasil analisis RCA menunujukkan komoditi SITC 422 dan 641 memiliki daya saing. Analisis ISP menunujukkan Indonesia sebagai eksportir komodti SITC 422 dan 641. Posisi pasar berdasarkan matriks EPD berbeda setiap komoditi tapi secra umum berada pada posisi falling star. Penelitian ini menggunakan pendekatan model permintaan ekspor untuk menganalisis faktor-faktor yang memengaruhi ekspor komoditas unggulan. Hasil analisis menunjukkan bahwa GDP per kapita riil negara tujuan, jarak ekonomi, harga ekspor riil, nilai tukar riil dan nilai RCA berpengaruh terhadap volume ekspor komoditas.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
