Judul: Daya saing dan strategi peningkatan ekspor udang Indonesia di pasar internasional
Abstrak: This research attempts to analyze the competitiveness of Indonesian shrimp export to Japan, the US (United States), and the EU-27 (European Union) in the three categories of products namely fresh, frozen, and prepared shrimp, compared to Thailand. Revealed Comparative Advantage (RCA) Index and Constant Market Share Analysis (CMSA) are used as indicators to provide insights into export performance. Using state data for 1989 to 2008 from Comtrade, this study has developed a simultaneous equations model that links between shrimp production and trade. The results show that Indonesia has a comparative advantage in exporting frozen and prepared shrimp products relative to fresh shrimp products. Moreover, the comparative advantage in exporting shrimp to Japan in the three categories of products has fallen after changing cultivation from Penaeus monodon (udang windu) to Penaeus vaname (udang vaname). Using CMSA model indicates that distribution effect and composition effect are still weak and Indonesian shrimp competitiveness is mainly because of specific competitiveness effect in exporting frozen shrimp to Japan and the US. Disease outbreaks, feed cost, and difficulties in fulfilling shrimp quality requirement especially from the EU-27 are the factors that affecting Indonesian shrimp competitiveness. To increase shrimp export competitiveness, the Indonesian government should revitalize Penaeus monodon, do more research on diseases, feed, seed, and broodstock, invest more on human development and irrigation, and differentiate its product to more value added products.

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: Pembuatan Film Tipis Lithium Niobat (LiNbO3) Menggunakan Metode Chemical Solution Deposition (CSD) dengan Variasi Kecepatan Putar (Rpm).
Abstrak: Film tipis merupakan salah satu aspek yang mendapat perhatian sangat besar dalam bidang material, karena film tipis merupakan material menarik yang memiliki sifat optik yang sangat tergantung pada konstanta dielektrik, indeks bias, dan energi gap. Lithium Niobat (LiNbO3 ) dapat digunakan sebagai pelapis pada film tipis karena memiliki sifat piezoelektrik, electrooptical, pyroelectrical dan photorefractive yang sangat baik. Film tipis Lithium Niobat (LiNbO3 ) ditumbuhkan menggunakan metode Chemical Solution Deposition (CSD) dengan variasi kecepatan 3500 rpm, 5000 rpm, 6500 rpm, dan 8000 rpm. Metode ini memiliki keunggulan dapat mengontrol stokiometri film tipis dengan kualitas yang baik, prosedur yang mudah dan membutukan biaya yang relatif murah. Energi band gap yang dihasilkan dari film tipis Lithium Niobat (LiNbO3) berkisar antara rentang 2.1 eV – 2.8 eV dengan indeks bias berada pada rentang 2.18-3.2. Film tipis LiNbO3 memiliki parameter kisi a=b=5.54Ǻ dan c = 16.35 Ǻ. Struktur morfologi film tipis adalah permukaan yang homogen dan ukuran kristal berada pada rentang 0.417 μm – 0.680 μm.
