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 Frozen Shrimp Exports in Main Destination Countries and Potential Countries
Abstrak: Komoditas udang berkontribusi besar terhadap total nilai ekspor subsektor perikanan di Indonesia. Tahun 2020 Indonesia menduduki peringkat ke-4 sebagai negara eksportir udang beku terbesar di dunia namun nilai ekspor komoditas tersebut masih berfluktuasi setiap tahunnya. Share volume ekspor udang beku Indonesia di pasar dunia masih rendah dibandingkan dengan negara pesaingnya yaitu Ekuador, India, dan Vietnam. Penelitian ini bertujuan menganalisis daya saing dan faktor-faktor yang memengaruhi ekspor udang beku Indonesia di enam negara tujuan utama. Hasil penelitian dengan menggunakan RCA menunjukkan bahwa ekspor udang beku Indonesia memiliki keunggulan komparatif di enam negara tujuan utama. Analisis EPD menjelaskan bahwa udang beku Indonesia hanya memiliki keunggulan kompetitif atau Rising Star di Kanada, sementara di pasar Amerika Serikat dan Belanda berada pada kondisi Falling Star, di pasar China pada kondisi Lost Opportunity, dan hasil yang lebih buruk di pasar Jepang dan Perancis berada pada kondisi Retreat. Faktor-faktor yang memengaruhi volume ekspor udang beku Indonesia secara signifikan dengan taraf nyata lima persen yaitu nilai harga udang beku Indonesia ke negara tujuan berpengaruh secara negatif dan jarak ekonomi yang berpengaruh secara negatif. Dua variabel lainnya tidak berpengaruh secara signifikan yaitu variabel GDP negara tujuan dan nilai tukar negara tujuan., Shrimp commodity contributes greatly to the total export value of the fisheries sub-sector in Indonesia. In 2020, Indonesia was ranked 4th as the largest frozen shrimp exporter in the world, but the export value of this commodity still fluctuates every year. Indonesia's frozen shrimp export volume in the world market is still low compared to its competitors, namely Ekuador, India, and Vietnam. This study aims to analyze the competitiveness and factors that influence Indonesia's frozen shrimp exports in six main destination countries. The results of the research using RCA show that Indonesia's frozen shrimp exports have a comparative advantage in the six main destination countries. EPD analysis explains that Indonesian frozen shrimp only has a competitive advantage or Rising Star in Kanada, while in the United States and the Netherlands markets are in Falling Star conditions, in the Chinese market in Lost Opportunity conditions, and worse results in the Japanese and French markets in retreat condition. The factors that significantly affect the volume of Indonesia's frozen shrimp exports with a significant level of five percent, namely the price value of Indonesian frozen shrimp to the destination country has a negative effect and economic distance has a negative effect. Two other variables have no significant effect, namely the destination country variable and the country's exchange rate.

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.
