Judul: The Competitiveness Analysis and The Factors Affecting Indonesian Footwear Export
Abstrak: Perdagangan ekspor yang dilakukan oleh Indonesia salah satunya ialah komoditi alas kaki yang juga merupakan satu dari sepuluh komoditi unggulan yang diekspor oleh Indonesia. Penelitian ini dilakukan untuk menganalisis daya saing ekspor alas kaki, menganalisis faktor-faktor yang memengaruhi ekspor alas kaki dan dinamika pasar ekspor alas kaki Indonesia ke negara tujuan. Data yang digunakan dalam penelitian ini adalah data sekunder yang diperoleh dari World Bank, ITC, CEPII dan WITS. Metode analisis menggunakan RCA dan EPD untuk mengetahui daya saing dan dinamika ekspor alas kaki, serta gravity model untuk menganalisis faktor-faktor yang memengaruhi ekspor alas kaki Indonesia. Hasil penelitian ini menunjukkan bahwa alas kaki Indonesia memiliki daya saing komparatif dengan nilai RCA yang lebih dari satu. Hasil estimasi EPD menunjukkan bahwa rata-rata terjadi pertumbuhan pangsa pasar dan permintaan ekspor alas kaki. Pada hasil gravity model menunjukkan bahwa variabel yang signifikan adalah GDP perkapita Indonesia, GDP perkapita negara tujuan, harga ekspor, populasi dan nilai tukar, sedangkan jarak ekonomi tidak berpengaruh.

Judul: Analysis of Indonesian Footwear Export Market Diversification and its Determinants
Abstrak: Alas kaki merupakan komoditas unggulan ekspor Indonesia. Namun, destinasi ekspor alas kaki Indonesia masih didominasi oleh beberapa negara sehingga rawan akan guncangan ekonomi global. Jika dibandingkan dengan negara pesaing yaitu China dan Vietnam, ekspor alas kaki Indonesia masih lebih rendah. Perlu dilakukan ekspansi pasar ekspor ke negara yang belum menjadi tujuan utama ekspor untuk mendorong kinerja perdagangan alas kaki Indonesia. Penelitian ini memiliki tujuan untuk menganalisis diversifikasi pasar ekspor alas kaki Indonesia dan determinannya. Metode STR digunakan untuk menganalisis negara tujuan ekspor, metode RCA, EPD, dan X-Model digunakan untuk mengetahui daya saing alas kaki Indonesia, dan regresi data panel digunakan untuk mengetahui faktor-faktor yang memengaruhi ekspor alas kaki Indonesia. Hasil penelitian memperlihatkan Indonesia memiliki daya saing yang kuat di negara Argentina, Austria, Brazil, Cili, Ceko, Yunani, Panama, Plandia, Spanyol, dan Swedia. Regresi data panel memperlihatkan bahwa nilai RCA, GDP negara tujuan ekspor, nilai tukar riil, dan harga ekspor memiliki pengaruh signifikan terhadap ekpor alas kaki Indonesia., Footwear is Indonesia, Footwear is Indonesia's leading export commodity. However, Indonesia's footwear export destinations are still dominated by several countries, making them vulnerable to global economic shocks. When compared with competing countries, namely China and Vietnam, Indonesia's footwear exports are still lower. It is necessary to expand the export market to countries that are not yet the main export destination to boost the performance of Indonesia's footwear trade. This research aims to analyze the diversification of the Indonesian footwear export market and its determinants. The STR method is used to analyze export destination countries, the RCA, EPD and X-Model methods are used to determine the competitiveness of Indonesian footwear, and panel data regression is used to determine the factors that influence Indonesian footwear exports. The research results show that Indonesia has strong competitiveness in the countries of Argentina, Austria, Brazil, Chile, Czech Republic, Greece, Panama, Poland, Spain and Sweden. Panel data regression shows that the RCA value, GDP of nonmain destination countries, real exchange rates, and export prices have a significant influence on Indonesian footwear exports.

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.
