Abstract
Dalam dunia perkapalan propeller merupakan unsur
penting sebagai salah satu penggerak dari kapal – kapal bermotor,
sedangkan dalam perancangan propeller sering terjadi kasus
bahwa kecepatan kapal tidak sesuai dengan kecepatan yang
dirancang sebelumnya. Hal tersebut dikarenakan adanya
penurunan kinerja dari propeller yang disebabkan terjadinya
kavitasi diantaranya adalah hub vortex cavitation. Adanya
kavitasi tersebut coba dihilangkan dengan Propeller Boss Cap
Fins (PBCF) yang diperkenalkan pertama oleh Mitsui O.S.K.
Lines, Japan Fluid Engineering Laboratory, dan Mikado Propeller
(Nakashima Mitsuwa Propeller) dari jepang pada tahun 1987. Hal
tersebut dibuktikan dengan adanya percobaan pada propeller
kapal MV Pagerungan dengan menggunakan analisa
Computational Fluid Dynamic (CFD), terdapat kenaikan
efisiensi sebesar ± 4% gaya dorong ± 1% dan penurunan torsi
kurang dari 2%, sekaligus menghilangkan efek kavitasi yang
terjadi.

In the world of shipping propeller is an important
element as one of the drivers of the boats - motorized vessels,
while in the design of the propeller often the case that the speed
of the ship is not in accordance with pre-designed speed. It is due
to the decline in the performance of propeller cavitation caused
them is the hub vortex cavitation. The presence of cavitation try
eliminated by Propeller Boss Cap Fins (PBCF) which was first
introduced in 1987 by Mitsui O.S.K. Lines, West Japan Fluid
Engineering Laboratory, and Mikado Propeller (Nakashima Mitsuwa
Propeller). This is evidenced by their experiments on propeller
ship MV Pagerungan by using analysis of Computational Fluid
Dynamics (CFD), there is an increase efficiency of ± 4%, thrust ±
1%, and decrease of torque is unless 2%, at the same time
eliminate the effects of cavitation occurs.
