Judul: Determinants of Indonesian Coffee Competitiveness in Eurasian Economic Union (EAEU) Market
Abstrak: Kopi adalah satu dari beberapa komoditas andalan ekspor Indonesia ke pasar EAEU. Tujuan yang ingin diraih, antara lain, melakukan analisis kondisi ekspor kopi dalam negeri dan kebijakan ekspor kopi di Indonesia, daya saing, potensi ekspor, serta faktor-faktor yang memengaruhi daya saing kopi Indonesia serta merumuskan strategi dalam upaya meningkatkan daya saing dan ekspor kopi Indonesia. RCA, EPD, X-Model, dan regresi data panel merupakan metode yang digunakan dalam penelitian ini. Analisis posisi dan pengembangan pasar dilakukan pada empat negara tujuan yang memiliki nilai RCA diatas satu. Hasil yang ditemukan dari analisis EPD menunjukkan terdapat dua negara tujuan memiliki pengembangan pasar potensial yang berada di posisi lost opportunity dan dua negara tujuan memiliki pengembangan pasar kurang potensial yang berada di posisi retreat. Hasil estimasi regresi menunjukkan variabel GDP per kapita negara tujuan, GDP per kapita negara Indonesia, dan volume ekspor memengaruhi tingkat daya saing kopi Indonesia secara signifikan., Coffee is one of Indonesia's main export commodities to the EAEU market. The objectives to be achieved include conducting an analysis of conditions of domestic coffee exports and coffee export policy in Indonesia, competitiveness, export potential, as well as the factors that influence the competitiveness of Indonesian coffee and formulating strategies in an effort to increase the competitiveness and exports of Indonesian coffee. RCA analysis method, EPD, X-Model, and panel data regression were used in this study. Position analysis and market development were carried out in four destination countries with RCA values above one. The results found from EPD analysis are that there are two destination countries that have potential market developments that are in position lost opportunity and two destination countries have less potential market development in position retreat. The results of the regression estimation show that the variables GDP per capita of destination countries, GDP per capita of Indonesia, and export volume significantly influence the level of competitiveness of Indonesian coffee.

Judul: Competitiveness Analysis and Affecting Factors of Indonesian Coffee Exports in the ASEAN Market
Abstrak: Kopi merupakan komoditas ekspor utama dan merupakan salah satu penghasil devisa terbesar dari sektor pertanian Indonesia. Penelitian ini bertujuan untuk menganalisis daya saing dan faktor yang memengaruhi ekspor serta memproyeksikan ekspor kopi Indonesia di kawasan ASEAN tahun 2021-2025. Metode yang digunakan yaitu Revealed Comparative Advantage (RCA), Export Product Dynamic (EPD), Rasio Akselerasi (RA), ARIMA, dan Gravity Model. Hasil RCA menunjukkan kopi Indonesia memiliki keunggulan komparatif di Kawasan ASEAN. Analisis EPD menunjukkan bahwa Indonesia hanya berdaya saing di negara Thailand dan Filipina, sedangkan Malaysia dan Singapura berada pada posisi retreat dan falling star. Berdasarkan analisis RA, Indonesia dapat merebut pasar ekspor kopi di kawasan ASEAN. Perkembangan ekspor kopi dipengaruhi oleh beberapa faktor. Hasil uji T menunjukkan bahwa GDP riil Indonesia, GDP riil pengimpor, jarak ekonomi, harga ekspor Indonesia memiliki pengaruh secara signifikan terhadap ekspor kopi Indonesia di kawasan ASEAN. Variabel populasi pengimpor memiliki pengaruh yang positif namun tidak signifikan terhadap volume ekspor kopi Indonesia di kawasan ASEAN. Hasil proyeksi juga menunjukkan bahwa pada tahun 2021- 2025, ekspor kopi Indonesia akan memiliki pertumbuhan yang positif, Coffee is one of the leading export commodities and the largest foreign exchange contributor from the Indonesian agricultural sector. This study aims to analyze competitiveness and the affecting factors of coffee exports and forecast the Indonesia's coffee exports in the ASEAN market in 2021-2025. The methods used are Revealed Comparative Advantage (RCA), Export Product Dynamic (EPD), Acceleration Ratio (AR), ARIMA, and Gravity Model. The RCA results show that Indonesian coffee has a comparative advantage in the ASEAN Region. EPD analysis shows that Indonesia is only competitive in Thailand and the Philippines, while Malaysia and Singapore are in a retreat and falling star position. Based on RA's analysis, Indonesia can seize the coffee export market in the ASEAN region. The development of coffee exports is influenced by several factors. The result of T-test shows that the Indonesia's real GDP, importers' real GDP, economic distance, Indonesia's export prices have a significant effect on the volume of Indonesia’s coffee export in the ASEAN region. The importing population has no significant effect to the volume of Indonesia’s coffee export in the ASEAN region. The forecasting results also show that in 2021-2025, Indonesia's coffee exports will have positive growth in the ASEAN Region.

Judul: Hydrothermal Synthesis of Biphasic Calcium Posphate
Abstrak: Biphasio calsium phosphate (BCP), which was a mixture of hydroxypatite (HA) and tricalcium phosphate (TCP), was synthesized by hydrothermal method followed by sintering process. Hydroxyapatite was produced by using natural calcium source CaO from hen's eggshell and (NH4)2HPO4 as phosphate souce, other hydroxyapatite sample was produce by using synthetic calcium source Ca(OH) and H3PO4 as phosphate source.
