Judul: The  competitiveness  of  indonesia’s  air  travel  service  and  the  determinants  of  demand  facing  open  sky  policy  aec  2015
Abstrak: Industri jasa penerbangan merupakan salah satu industri utama Indonesia yang bergerak di bidang jasa dan memiliki potensi yang sangat besar. Namun, dengan adanya kebijakan open sky policy sebagai bagian dari Masyarakat Ekonomi ASEAN 2015 akan memberikan tantangan baru bagi industri jasa penerbangan nasional. Pelaku usaha industri jasa penerbangan nasional harus siap bersaing dengan pelaku usaha dari berbagai negara ASEAN dalam memperoleh pasar. Penelitian ini bertujuan untuk menganalisis keunggulan komparatif jasa penerbangan nasional di pasar internasional, keunggulan kompetitif industri jasa penerbangan nasional, dan menganalisis faktor-faktor yang memengaruhi permintaannya. Hasil penelitian menunjukkan bahwa industri jasa penerbangan nasional memiliki keunggulan komparatif dan keunggulan kompetitif. Faktorfaktor yang memengaruhi permintaan jasa penerbangan adalah produk domestik bruto, populasi, harga avtur, dan armada yang berpengaruh positif secara signifikan, sedangkan konsumsi rumah tangga berpengaruh negatif secara signifikan terhadap permintaan jasa penerbangan nasional., Air travel industry is one of main service industries in Indonesia and has a great potential. The Open Sky Policy as a part of ASEAN Economic Community 2015 will give other challenges for the Indonesian’s air travel industry. Every player of the Indonesia’s air travel industry has to be ready to compete with air travel industry’s players from other ASEAN countries to get market share. This research is aimed to analyze the comparative advantage of Indonesian air travel industry in international market, the competitive advantage of Indonesian air travel industry, and analyze determinants of the air travel demand in Indonesia. The results show that Indonesia’s air travel industry has comparative advantage and competitive advantage. The determinants of air travel demand are GDP, population, avtur price, and aircraft with positive and significant effects, and household consumption with negative and siginificant effect.

Judul: Synthesis of Biphasic Calcium Phosphate Made of Eggshells Through A Hydrothermal Method
Abstrak: Biphasic Calcium Phosphate mixed of hydroxyapatite and tricalcium phosphate. A hydrothermal method of synthesizing by mixing CaO as calcium source and (NH4)2HPO4 as phosphate source with distilled water. CaO got from calcination process made of eggshells. All samples were synthesized using hydrothermal reactor then followed by sintering process. The molar ratio of Ca and P for all samples was 0.5 M : 0.3 M. Hydrothermal temperature and sintering temperature were variated they are 250 ºC, 300 ºC for hydrothermal and 800 ºC, 900 ºC, 1000 ºC for sintering, higher treatment temperature, tricalcium phosphate appears. Final results of synthesis were characterized by using X-ray Diffraction and Fourier Transform Infrared. X-ray Diffraction patterns was ecompared with database Join Committee on Powder Diffraction Standards and found tricalcium phosphate and hydoxyapatite.
