Judul: Analisis dayasaing dan faktor-faktor yang memengaruhi permintaan ekspor kakao olahan Indonesia di negara kawasan
Abstrak: Indonesia merupakan salah satu negara produsen kakao terbesar di dunia. Kebijakan tarif biji kakao dan perjanjian dagang antar negara diharapkan dapat meningkatkan permintaan ekspor kakao olahan. Penelitian ini bertujuan untuk menganalisa dayasaing dan faktor yang memengaruhi ekspor kakao olahan. Berdasarkan analisa RCA, Indonesia telah berdayasaing dan berdasarkan EPD, ekspor kakao olahan Indonesia menduduki posisi falling star dan retreat. Hasil dari regresi data panel menunjukkan ekspor kakao pasta dipengaruhi secara signifikan oleh nilai tukar, dayasaing kakao olahan Indonesia, dan kebijakan perjanjian dagang. Ekspor kakao butter dipengaruhi secara signifikan oleh PDB total, nilai tukar, dan kebijakan perjanjian dagang. Ekspor kakao powder dipengaruhi secara signifikan oleh PDB total, nilai tukar, dayasaing kakao olahan Indonesia, dan kebijakan perjanjian dagang.

Judul: Analisis Dayasaing Olahan Kakao Indonesia di Negara Tujuan Utama Ekspor setelah Penetapan Tarif Ekspor.
Abstrak: Indonesia merupakan salah satu negara dengan penghasil biji kakao terbesar di dunia. Penetapan tarif ekspor pada biji kakao diharapkan dapat meningkatkan ekspor kakao dalam bentuk olahan. Penelitian ini dilakukan untuk menganalisis dayasaing dan faktor-faktor yang memengaruhi ekspor kakao olahan Indonesia di negara tujuan utama ekspor. Berdasarkan hasil analisis RCA, kakao olahan Indonesia sudah berdayasaing cukup kuat di negara tujuan utama ekspor. Hasil analisis regresi data data panel menunjukkan bahwa faktor-faktor yang memengaruhi ekspor kakao pasta adalah volume ekspor, nilai tukar riil Indonesia dan penetapan tarif ekspor biji kakao. Pada kakao powder faktor-faktor yang memengaruhi adalah volume ekspor, harga ekspor, dan penetapan tarif biji kakao. Sedangkan pada kakao butter, faktor yang memengaruhi adalah volume ekspor dan nilai tukar riil Indonesia.

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.
