Irwan Dwi Saputra, NIT. 49124575.T, 2017 " Leakage Analysis of Hydraulic Pump Steering Gear With The Ship Rudder in MT.Pelita Energy", Diploma Program IV, Teknika, Sailing Semarang Polytechnic Sciences, Supervisor I :. Sarifuddin, M.Pd, M.Mar.E, and Supervisor II :. Captain Budi Mantoro, M, Si, M.Mar Steering Gear is a prayer One Machining System The auxiliary steering system used to review Ship to review the operation of the vessel Keeping Still Go Right when the ship did Movement From the Start Point to point Towards End Of A Port. Background Singer thesis is ketidakoptimalan boarding costs AT Hydraulic pump steering gear, thus experiencing leaks Hydraulic pump ON. The problems ON Research Singer Was factors Anything That led AT Hydraulic steering gear pumps Leak Impact ?, What can be Occurs when experiencing Leaks Hydraulic pump? And how the APA Should efforts undertaken to review Maintaining optimal boarding costs AT Hydraulic Systems on Ships? The method used by writer is descriptive research methodology WITH Fishbone methods for the review identify problems NOT maximal Steering gear. Results obtained Risks That posed From the lack Care Steering gear is NOT BECAUSE Air leaking Yang SIGN hearts Systems, because the surface of the oil hearts Hydraulic Tank Still ON Limit Line that intake pipe Still Below the surface of the oil, so does NOT suck Air Operating both, IN EACH The connection allows the shaft seal leaks such as pumps, piping connection tubing OR (connector). Discussion of the issue for review execute Care Planning Steering gear ON WITH implement WITH Periodic Maintenance Planning and Starting of daily treatments, Weekly, Monthly And. CONCLUSION Of Research Singer Is The Risks arising from the lack of AT Care Steering gear Disorders That is the fatal That led Hydraulic pump leak. It marked WITH singer steering gear Components That Can not afford WORK Operates optimal. Treatment methods of steering gear must be made properly and regularly according to the schedule so the damage has programmed AT steering gear can be avoided.
