This research aims to quantify the specialization stage of Indonesia, followed by the dependencies of Indonesia's imports on the aerospace sector. Since, there are still few studies about the aerospace sector, especially from an economic perspective. This research conducted to fulfill the gap studies on international trade aerospace sector phenomenon. The sample used in this research is 9 countries between 2001 – 2018. Methods will be conducted in two steps. First, by using Trade Specialization Index (TSI), we try to identify the specialization stage of each country in the aerospace sector. Second, we used Import Dependency Ratio (IDR) to identify the level of Indonesia's dependency in the aerospace sector on other countries. We found that Indonesia still reaching the introduction stage of specialization. Adding relevancy to the result, Indonesia is also considered as highly-dependent on other countries in terms of the aerospace sector. We therefore suggest that Indonesia needs to raise traction in the aerospace sector by increasing its budget and conducting technology transfers, so Indonesia’s competitiveness will raised.

Space technology keeps innovating and giving us the benefit to make our life easier, including satellite banking. However, BRI become the first bank that own satellite and claims it could improve efficiency. Therefore, this research aims to look at the efficiency of selected banks in Indonesia and its productivity growth on efficiency by the satellite ownership. We also want to examine if the ownership of the satellite could impact bank efficiency. Methods that will be used are divided into two steps, which are DEA and Tobit regression. The result of this research shows us that bank BRI achieves the highest efficiency and productivity growth, compared with other selected banks. The ownership of satellites also has a positive significant impact on bank efficiency. It could be implied that owning satellite for banks is beneficial, policymakers should increase budget spending and other banks could own satellite.
