To meet the high demand of aircraft maintenance technicians in Indonesia, higher education redesigns its curriculum to fit the needs of aircraft maintenance industry . Higher education has made drastic changes to align its standards of practice under Perpres RI No. 8/2012 KKNI with industry standards under Civil Aviation Safety Regulations (CASR) Part 147 and CASR Part 65 recommended by Directorate General of Civil Aviation (DGCA), the Ministry of Transportation RI. By 2015, eight institutions including Politeknik Negeri Batam, Politeknik Negeri Medan, Politeknik Negeri Sriwijaya, Politeknik Negeri Bandung, Politeknik Negeri Malang, Politeknik Negeri Jakarta, Universitas Suryadharma, and Sekolah Tinggi Teknologi Adisutjipto, have adopted aircraft maintenance curriculum initiated by PT GMF AeroAsia in their diploma programs. By analyzing the newly adopted curriculum, this paper finds that the recognition of prior learning (RPL) is very potential to be implemented in Indonesia to not only meet client demands but also enhance social equity, access and inclusion in higher education. The implementation of RPL would be a breakthrough in Indonesian Aeronautical Engineering education system to bridge the gap between academic degrees and industry standard licenses. Last but not least, this paper also proposes some guidelines to facilitate an effective implemetation of RPL.

This paper focuses on the development of Quadcopter F3. Computational Fluid Dynamic (CFD) method was used to analyze the fluid flow characteristics around three main frames profiles designs, such as the lift generation for each angle of attack and longitudinal stability caused by vortex generation on trailing edge. The results show that the design of the disc-shaped main frame has an optimal aerodynamic characteristics with the value of Cl = 0.719 at 30 degrees of angle of attack and the maximum ratio Cl/Cd of 2.836. The material tensile strength test obtained that fibre carbon with epoxy resin has the optimum value of mechanical properties with tensile strength of 97.341 GPa and Modulus Young of 2140.300 GPa, while the material chosen for the frame arm analyzed through computational calculation by using the structural strength von mises stress by assuming quadcopter in maneuvering condition. The result obtained that it is safe with von mises stress of 2.769 MPa, and safety factor of 15.

All around the world, a rapid growth of energy demand during the last decades. An ideal alternative to meet this additional increasing demand would be through renewable energy resources such as wind energy. With over 300 GW of installed wind capacity worldwide and the target for future increase of capacity of more than 15% per year, the research to improve wind energy technology is further required. For countries around the equator where wind speed is low, the need for new innovative design of wind turbine for low wind speed condition or class 1 wind is of primary urgency. A new type of airfoil for low wind speed turbine blade need to be designed.
The objective of this study is to investigate the design parameters influencing the performance of three blades Horizontal Axis Wind Turbine (HAWT). Blade Element Momentum Theory was used to find the optimal performance, in term of the coefficient of power (Cp), which rates the turbine blade’s ability to extract energy from the available wind stream.
The result shows the relationship between the changes of the power coefficient with tip speed ratio. The maximum power coefficient found was 0.57 at tip speed ratio 4.8. It was then shown that Cp reduced for higher tip speed ratio.

This paper presents the Empirical Numerical Method for the analysis of the performance characteristics of generic bell 206B helicopter tail rotor blade. The airfoil profile of the blade is near similar to NACA 0012 series, with maximum thickness 12% at 33% chord. This analysis work deals with the comparative study of variation in an angle of attack over the blade at different speed which using the software programming application that developed base on this empirical method. The analysis results were validated by comparing with the experimental result that have already done before. The empirical were successfully shown to be able to obtain an optimal set of parameters leading to performance characteristics of the tail blade.

It currently no information is available for the comparison of the dynamic behaviour of the internal turret moored for twin hull FPSO system at different loading conditions with various turret locations under the action of wave. Hence, the present study investigated characteristics for a typical turret moored FPSO system by catenary anchor leg mooring (CALM) which subjected to sea waves, in order to get insight knowledge on its dynamic behaviour due to various turret locations with different loading conditions. The comparison of the dynamics behaviour to the FPSO and it mooring lines are important when choosing potential development and optimal options. This research will analyses and highlight the optimal turret location to the new potential concepts of twin hull FPSO. It also will highlight areas where effort is best focussed to mitigate the marine risks.
