Judul: Dampak ASEAN Single Window terhadap ekspor kelapa olahan Indonesia ke negara-negara intra-ASEAN
Abstrak: ASEAN menjadi asosiasi regional yang fokus pada pengembangan integrasi ekonomi. Salah satu bentuknya yaitu penetapan produk pertanian sebagai satu dari 12 sektor prioritas yang diintegrasikan menjelang pembentukan ASEAN Economic Community (AEC). Kelapa sebagai produk pertanian memiliki kontribusi yang cukup besar dalam perekonomian Indonesia. ASEAN Single Window menjadi salah satu bentuk dari fasilitasi perdagangan di kawasan ASEAN yang diharapkan dapat mengoptimalkan ekspor komoditi kelapa olahan Indonesia. Penelitian ini bertujuan untuk menganalisis dampak ASEAN Single Window terhadap volume ekspor kelapa olahan Indonesia ke negara-negara ASEAN dengan periode penelitian 2007-2013. Hasil penelitian menunjukkan bahwa indikator ASEAN Single Window yaitu indeks efisiensi pelabuhan, indeks e-business, dan dummy pemberlakuan ASEAN Single Window berpengaruh positif dan signifikan, sedangkan indeks custom environment berpengaruh negatif dan signifikan terhadap volume ekspor kelapa olahan Indonesia. Variabel lainnya yang juga berpengaruh signifikan yaitu GDP per kapita riil negara tujuan, harga ekspor, nilai tukar riil, GDP per kapita riil Indonesia, dan jarak ekonomi.

Judul: Efficiency and Determinants of Export Inefficiency of Indonesia’s Five Largest Agricultural Commodities to Several ASEAN Countries
Abstrak: Perdagangan internasional memainkan peranan penting dalam pertumbuhan ekonomi ASEAN. Pembentukan Masyarakat Ekonomi ASEAN (MEA) merupakan salah satu upaya untuk peningkatan arus perdagangan internasional. Sektor pertanian menjadi sektor penting sebagai penyumbang surplus terhadap neraca perdagangan Indonesia dan mampu bertahan di tengah ketidakpastian global. Penelitian ini bertujuan untuk menganalisis nilai efisiensi ekspor sebelum dan sesudah kesepakatan MEA serta determinan ekspor dan inefisiensi ekspor lima komoditas pertanian terbesar Indonesia ke beberapa negara ASEAN periode 2003-2022. Metode yang digunakan dalam penelitian ini adalah Stochastic Frontier Gravity Model. Hasil analisis menunjukkan bahwa nilai rata-rata efisiensi ekspor lima komoditas pertanian terbesar Indonesia setelah kesepakatan MEA sebesar 45,25 persen yakni turun 12,34 persen dari sebelum kesepakatan MEA. Variabel GDP riil Indonesia dan jarak ekonomi berpengaruh negatif dan signifikan terhadap ekspor pertanian Indonesia, sedangkan GDP riil mitra dagang berpengaruh positif dan signifikan. Secara rata-rata, variabel trade openness, nilai tukar riil, business freedom, government effectiveness, liner shipping connectivity index, dan dummy communication language berpengaruh negatif dan signifikan terhadap inefisiensi ekspor pertanian Indonesia, sedangkan tax burden dan dummy Masyarakat Ekonomi ASEAN (MEA) berpengaruh positif dan signifikan., International trade played an important role in ASEAN economic growth. The establishment of the ASEAN Economic Community (AEC) was one of the efforts to increase international trade flows. The agricultural sector was significant as a contributor to the surplus on Indonesia’s trade balance and managed to survive amid global uncertainty. This study aimed to analyze the value of export efficiency before and after the AEC agreement, as well as the determinants of export and export inefficiency for Indonesia’s five largest agricultural commodities to several ASEAN countries during the period 2003-2022. The method used in this study was the Stochastic Frontier Gravity Model. The analysis results showed that the average value of export efficiency for Indonesia’s top five agricultural commodities after the AEC agreement was 45,25 percent, which decreased by 12,34 percent compared to before the AEC agreement. Indonesia’s real GDP and economic distance variables had a negative and significant effect on Indonesian agricultural exports, while the real GDP of trading partners had a positive and significant impact. On average, variables such as trade openness, real exchange rate, business freedom, government effectiveness, liner shipping connectivity index, and communication language dummy had a negative and significant effect on the inefficiency of Indonesia’s agricultural exports, while tax burden and the ASEAN Economic Community (AEC) dummy variable had a positive and significant impact.

Judul: Photosensor producing based on ferroelectric material of Ba0,5Sr0,5TiO3 doped by Ferrium Oxide (Fe2O3) on a P-Type Silicon Substate Si (100) applied as a digital camera with a single pixel image sensor
Abstrak: Thin film Ba0,5Sr0,5TiO3 (BST) doped with Fe2O3 was grown on p-type silicon substrate (100) using chemical solution deposition (CSD). It used the solvent 2-methoxyethanol with annealing temperature of 850°C and the doping treatment Fe2O3 of 2.5, 5, 7.5, 10 % of the mass formed BST. Pure BST had the highest absorption of 600 nm of light wavelength. Additions Fe2O3 moves highest absorption in the range of 560 nm. Fe2O3 addition was strengthening thin film sensitivity to the effects of light. In general, doping Fe2O3 10% was result the best absorbance and current-voltage of BST thin film. Electrical properties of thin films BST include dielectric, photoconductivity, and dissipation energy. Based on the current-voltage (I-V) analysis, pure BST and doped BST showed photodiode properties. Dielectric values obtained in the range from 23.32 to 243. Based on electrical conductivity data and energy dissipation, BST thin films have shown photodiode characteristics and are therefore suitable as light sensors. The image sensor in a digital camera is also a light sensor. This BST thin film has been scientifically proven to be a light sensor and also it can be applied as an image sensor. This is a novelty image sensor based on thin film Ba0.5Sr0.5TiO3.
