Judul: Competitiveness Analysis and Affecting Factors of Indonesian Frozen Shrimp Exports in the ASEAN Market
Abstrak: Indonesia merupakan eksportir udang beku terbesar ke-4 di dunia. Pasar tujuan ekspor terdekat Indonesia adalah ASEAN, yaitu Filipina, Malaysia, Singapura, Thailand, dan Vietnam. Nilai ekspor udang beku Indonesia ke ASEAN lebih rendah dari Vietnam dan India, serta menurun dalam beberapa tahun terakhir. Penelitian ini bertujuan untuk menganalisis daya saing udang beku Indonesia di pasar ASEAN dan faktor-faktor yang memengaruhi ekspor udang beku Indonesia ke pasar ASEAN. Analisis menggunakan metode Revealed Comparative Advantage (RCA) menunjukkan udang beku Indonesia berdaya saing komparatif pada semua negara tujuan di ASEAN, namun lebih rendah dibandingkan Vietnam dan India. Analisis menggunakan metode Export Product Dynamic (EPD) menunjukkan posisi pasar udang beku Indonesia rising star di Filipina dan Malayisa, retreat di Singapura dan Vietnam, serta lost opportunity di Thailand. Analisis Porter’s Diamond menunjukkan faktor kondisi, industri terkait dan pendukung, strategi, struktur, dan persaingan perusahaan, peran pemerintah, dan kesempatan merupakan kekuatan Indonesia, sedangkan faktor permintaan merupakan kelemahan Indonesia dalam mendukung ekspor udang beku ke ASEAN. Estimasi gravity model menunjukkan jarak ekonomi, GDP perkapita negara-negara ASEAN, dan volume ekspor udang beku Indonesia ke ASEAN berpengaruh positif terhadap nilai ekspor udang beku Indonesia, sedangkan GDP perkapita Indonesia berpengaruh negatif terhadap nilai ekspor udang beku Indonesia ke ASEAN.

Judul: Competitiveness and Factors Affecting Indonesian Shrimp Exports to Main Destination Countries
Abstrak: Penelitian ini bertujuan menganalisis daya saing dan faktor-faktor yang memengaruhi volume ekspor udang Indonesia ke negara-negara tujuan utama. Komoditas yang menjadi objek pada penelitian ini adalah udang beku dan udang olahan. Daya saing dianalisis menggunakan metode Revealed Comparative Advantage (RCA) sedangkan faktor-faktor yang memengaruhi ekspor dianalisis menggunakan gravity model, dalam kurun waktu 2005-2019. Udang beku dan udang olahan Indonesia memiliki daya saing di negara tujuan utama. Variabel yang signifikan memengaruhi volume ekspor udang beku dan udang olahan Indonesia adalah Gross Domestic Product (GDP) riil per kapita Indonesia, Gross Domestic Product (GDP) riil per kapita negara tujuan, jarak ekonomi, harga udang, kebijakan tarif bea masuk, dan kebijakan non tarif, sedangkan nilai tukar tidak berpengaruh signifikan., This study aims to analyze the competitiveness and the factors that influence the volume of Indonesian shrimp exports in the main destination countries. The commodities that are the object of this research are frozen shrimp and processed shrimp. Competitiveness is analyzed using the method Revealed Comparative Advantage (RCA)while the factors that affect exports are analyzed using the gravity model, in the period 2005-2019. Indonesian frozen and processed shrimp have competitiveness in the main destination countries. Variables that significantly affect the export volume of frozen and processed shrimp in Indonesia are the real Gross Domestic Product (GDP) per capita of Indonesia, the real Gross Domestic Product (GDP) per capita of the destination country, economic distance, shrimp prices, import duty tariff policies, and non-tax policies. Rates, while the exchange rate has no significant effect.

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.
