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: Competitiveness, Dynamics, and Determinats of Indonesian Sport Footwear Exports to Main Destination Countries
Abstrak: Alas kaki merupakan komoditas unggulan ekspor Indonesia. Ekspor alas kaki Indonesia didominasi sepatu olahraga. Namun, Indonesia menghadapi persaingan ketat antar negara eksportir sepatu olahraga dan menurunnya pangsa pasar ke negara tujuan utama tahun 2018–2020. Tujuan penelitian ini menganalisis daya saing dan dikomparasikan dengan pesaing, dinamika, serta determinan ekspor sepatu olahraga Indonesia ke 10 negara tujuan utama periode 2011–2020. Metode penelitian ini yaitu RCA, EPD, X-Model, porter’s diamond dan regresi data panel. Hasil RCA menunjukkan sepatu olahraga Indonesia berdaya saing komparatif yang kuat. Hasil EPD menggambarkan posisi pasar rising star, falling star, dan retreat. Hasil X-Model menunjukkan pengembangan pasar optimis, potensial, dan kurang potensial. Hasil regresi data panel menunjukkan PDB riil Indonesia dan negara tujuan, harga, nilai tukar riil, daya saing, dan jarak ekonomi berpengaruh signifikan terhadap volume ekspor sepatu olahraga Indonesia. Hasil porter’s diamond menunjukkan daya saing kompetitif industri alas kaki Indonesia kuat berdasarkan pada sebagian besar faktor penting yang berpengaruh positif terhadap daya saing., Footwear is Indonesia's leading export commodity. Indonesian footwear exports are dominated by sports shoes. However, Indonesia faced stiff competition and declined market share to the main destination countries in 2018–2020. The purposes of this study is to analyze competitiveness and compare with competitors, dynamics, and determinants of Indonesian sports shoe exports to 10 main destination countries for the period 2011–2020. The research methods are RCA, EPD, X-Model, porter's diamond and panel data regression. The RCA results showed that Indonesian sports shoes had strong comparative competitiveness. The EPD results described the rising star, falling star, and retreat market positions. X-Model results showed an optimistic, potential, and less potential market development. The panel data regression result showed that Indonesia's and destination countries real GDP, prices, real exchange rates, competitiveness, and economic distance had a significant effect on export volume of Indonesian sports shoes. The porter's diamond results showed that the competitive competitiveness of Indonesian footwear industry is strong, based on most of the fundamental factors had a positive effect on competitiveness.

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.
