Abstract

Penggunaan wahana udara tanpa awak (UAV) yang semakin meluas mendorong perkembangan perancangan propeler modern ke arah peningkatan performa dan pengurangan tingkat kebisingan. Studi pada winglet propeler dan propeler tipe toroidal dilakukan secara numerik CFD untuk membandingkan gaya dorong, daya dan efisiensinya dengan propeler biasa / konvensional APC 20x10.  Simulasi CFD dilakukan dengan metode Frozen Rotor dan Periodik Rotasional pada putaran 3000 RPM dan 5 kecepatan aliran. Hasil simulasi menunjukkan propeler winglet justru mengalami penurunan efisiensi sebesar 1% dan penurunan gaya dorong sebesar 5% sedangkan propeler toroidal menunjukkan peningkatan efisiensi 6% walaupun gaya dorong turun 10% dibandingkan propeler biasa. Propeler toroidal juga memiliki distribusi tekanan yang lebih merata sepanjang bilah yang mengindikasikan tip vortex yang sangat rendah. Studi pengaruh variasi rancangan winglet atau toroidal terhadap pembentukan tip vortex dan performa propeler dapat dikembangkan lebih lanjut untuk mendukung pengembangan UAV yang ramah lingkungan.

Abstract

The Pre-Delivery Installation (PDI) Department of PT. XYZ is tasked with carrying out the installation process of imported heavy equipment attachment units, including one of the leading excavator units. Obstacles that arise can affect installation productivity. The gap between the actual installation results of 78 units and the company's target of 156 units requires a solution or resolution to improve the process that can be implemented. Therefore, it is necessary to investigate the wait time associated with decreased productivity, which is the longest component of the installation process. This work has a purpose to analyze lead time of the excavator attachment unit installation process. The method is applied with a time study approach referring to data sheets and observations, then processing lead time data using pie charts, Pareto diagrams, and fishbone diagrams. Furthermore, we review the planning calendar, realization, and improvement engineering. Reduction is carried out by providing additional work personnel and procuring sanding machine tools to reduce the installation and critical time of the planning calendar. The realization condition for 562 minutes with the implementation of improvement engineering is reduced to 318 minutes. Thus, it can speed up implementation time of the excavator attachment in unit installation process to 224 minutes or 44%.
