Abstract

ABSTRACK Dri Achmad Jabar Falakh, 2022, NIT : 551811226678.T, "Analysis of leaks in the rudder shaft on the steering gear machine at MV.Manalagi Asta”, Diploma IV Study Program, Marine Science Poliytecnic Semarang, Advisor I : H. Amad Narto, M.Pd.,Mar. E., Advisor II : Capt. Trikismantoro, M.MM. Mar Steering gear is one of the auxiliary machinery and important equipment on board the ship. The steering gear functions to help the ship turn left (port side) and right (starboard side) by moving the rudder (rudder). In operation, the steering gear contained in MV. Manalagi Asta has a leak through a gap in the rudder shaft which causes seawater to overflow to fill the steering gear room and if it is not stopped immediately it can damage the auxiliary machinery around the area. This study aims to determine the factors that cause leaks in gland packing installation, the impact caused if leaks in gland packing installation are not repaired immediately, and to provide information to readers about efforts to overcome the problem of leaking gland packing installation on the steering gear engine at MV.Manalagi Asta. This study uses a research method, namely SHEL (Software, Hardware, Environment, and Liveware.) and FISHBONE. The model of this method relates to and relates between human factors and surrounding environmental resources. The SHEL method is to determine the factors, impacts and effort factors of non-optimal Steering Gear work. The results of the study show that the factors that cause leakage in the installation of gland packing on the steering gear machine are the use of inappropriate materials in covering or wrapping the rudder shaft. The impact arising from a leak in the installation of the gland gasket on the steering gear machine is the overflow of seawater which can cause damage to the auxiliary machinery in the area if it is not repaired immediately. Efforts are being made to stop the leakage of the gland packing installation immediately by carrying out temporary repairs so that the leak does not continue and drain the overflow of sea water so that it does not cause damage to the machinery around the area and cause a loss in repair costs and ship operational time. All of that will be discussed by researchers in this thesis.
