Judul: Determinants Export of Indonesian Frozen Shrimp in Traditional Country
Abstrak: Udang merupakan salah satu komoditas ekspor unggulan Indonesia. Ekspor udang Indonesia dalam sepuluh tahun terakhir berfluktuasi. Salah satu strategi yang dapat dilakukan untuk meningkatkan kinerjanya dengan mengekspor ke negara tradisional. Penelitian ini bertujuan untuk menganalisis determinan ekspor dan faktor-faktor apa saja yang mempengaruhi ekspor udang beku Indonesia ke negara tradisional. Metode yang digunakan dalam penelitian ini adalah Gravity Model. Hasil Gravity Model menunjukkan bahwa GDP riil negara pengimpor dan harga ekspor berpengaruh positif dan signifikan terhadap volume ekspor udang beku, sedangkan GDP riil Indonesia dan nilai tukar riil signifikan berpengaruh negatif. Sementara jarak ekonomi tidak signifikan berpengaruh terhadap volume ekspor udang beku Indonesia, Shrimp is one of leading export commodities in Indonesia. Indonesia shrimp exports in the last ten years has fluctuated. Its export performance can be improve by export to the traditional contries. This study aims to analyze the determinants of exports and what factors effect the export of Indonesian frozen shrimp in traditional countries. The method used in this research are Gravity Model. The Gravity Model show the real GDP of importer and the price of exports have positively effect quantity of Indonesian frozen shrimp export, meanwhile the real GDP of Indonesia and real exchange rate have negatively effect quantity of Indonesian frozen shrimp export. While the economic distance does not significantly effect quantity of Indonesia's frozen shrimp exports

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: Photovoltaic Effect In A CdS/P3HT-Chitosan Junction
Abstrak: A CdS/Polymer junction has been fabricated and it’s photovoltaic effect has been studied. The polymer is a blend of poly-3hexyltiophene (P3HT), chitosan and polyethileneglicol (PEG). Boron in situ doping of CdS using Chemical Bath Deposition (CBD) was investigated. The effect of B-doping and annealing on optical properties as well as on electrical and morphology of CdS film were studied. The structure and morphology of the film were detected by XRay Diffraction (XRD) and Scanning Electron Microscopy (SEM). The polymer film was sandwiched between the CdS semiconductor and an ITO glass to form an ITO/CdS/Polymer/ITO photovoltaic cell. Time constant (τ) and open circuit voltage (Voc) were investigated by using voltage censor. The bandgap of films were determined using absorbance edge method. The results of annealing optical bandgap of undoped CdS shifted from 2,49 eV down to 2,39 eV. Phase transition of CdS due to annealing temperature and induced lattice damage due to doping. The room temperature conductivity of polymer is 3,8 – 6,6 x 10-7 S/cm as function of frequency between 100 – 5000 Hz. The Voc of the fabricated cells ranges between 107 – 286 mV and time constant ranges between 2,5 to 43,75 s.
