Judul: The Competitiveness and Affecting Factors Analysis of  Indonesian Freshwater Ornamental Fish Export
Abstrak: Indonesia has great potential in the marine and fishery sector with excellent export products is marine consumption fish and live fish. Freshwater ornamental fish is a type of live fish that is Indonesian leading export commodity. The aims of this study to analyze competitiveness and the affecting factors of Indonesian freshwater ornamental fish export to 10 main destination countries period 2014- 2020. The study used RCA, EPD, X-Model and panel data regression methods. RCA method showed that Indonesian freshwater ornamental fish have strong competitiveness in 10 destination countries. EPD method showed the rising star and falling star market position. X-Model showed that optimistic market developments are in the United States, China and Canada. Meanwhile, the other seven destination countries have potential market development. Based on panel data regression analysis, export prices, economic distance, and the exchange rate have a negative significant effect of Indonesian freshwater ornamental fish export volume. Meanwhile, the population and the real GDP per capita have a positive significant effect.

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.
