Abstract
Salah satu bagian paling penting dari kapal selain
konstruksi dan mesin terdapat propeller sebagai sistem
propulsi berupa baling-baling, berputarnya propeller akan
menghasilkan daya dorong yang akan membuat kapal
dapat berlayar, Pada kapal MV.Meratus Barito dilakukan
modifikasi daun propeller dikarenakan terjadi overload
pada mesin dan berakibat berkurangnya sea margin
pelayaran, sea margin sangat penting sebagai daya
cadangan karena saat pelayaran terdapat ombak besar dan
hewan laut yang menempel pada kulit kapal, untuk
memenuhi kebutuhan standar sea margin maka dilakukan
modifikasi berupa pemotongan daun propeller untuk
mengurangi beban mesin dan dapat menambah persentase
sea margin.
Proses modifikasi daun propeller yang dilakukan
terlebih dahulu membuat gambar 4 model propeller dengan
ukuran diameter 2700 mm,2650 mm,2600 mm dan 2550
mm.Setelah pembuatan model selesai 4 model tersebut di
simulasikan sehingga dapat di ketahui
pressure,torque,.area dan wall shear. Sehingga data yang
di didapat yaitu daya propeller, efisiensi propeller, thrust
dan torsi. hasil dari modifikasi propeller MV.Meratus
Barito propeller yang dipilih yaitu dengan diameter 2600
mm mempunyai sea margin 15% dan efisiensi 0,537.

One of the most important parts of the ship beside
construction and machinery there is propeller as system
propulsion in ship, output from propeller spins will generate
thrust and make the ship can sail, MV.Meratus Barito
propeller modification occurred due to overload on the
machine and result in reduced sea margin when sailing, sea
margin is very important as the emergency power when there
are big waves and barnacle or fouling on shell, to get
standart of sea margin the leaf propeller need to modify with
cut the trail edge to reduce engine load and can increase the
percentage of sea margin .
Propeller blade modification process is make the i 4
models of propeller with a diameter of 2700 mm , 2650 mm ,
2600 mm and 2550 mm. than manufacture of the finished 4
models are simulated so as to be in the know of pressure ,
torque , and wall shear .area , So that the obtained are in
power propeller , propeller efficiency , thrust and torque . the
result of the modification of propeller MV.Meratus Barito
propeller with a diameter of 2600 mm which has a 15 % sea
margin and efficiency of 0.537.
