ANALYSIS OF THE INFLUENCE OF LOAD UNBALANCED ON NEUTRAL CURRENT IN FISHING VESSEL ELECTRIC GENERATOR CASE STUDY AT KM. PULAU PINANG

Many studies have been conducted on load imbalance in 3-phase electrical installations, but research on the effects of unbalanced electrical loads on 3-phase electrical installations in fishing vessel generators has not been carried out. This study aims to determine the percentage value of load imbalance in the 3-phase electrical installations of KM fishing vessels in Pulau Pinang and observe its effect on the emergence of electric current in the neutral conductor cable in the electrical installation. The Indonesian Classification Bureau (BKI) in Volume IV rules for 2019 and 2022 regarding Electrical Installation on Ships requires that, under normal operating conditions, the percentage value of load imbalance in each phase must not exceed 15%. The research was conducted in three stages: March, April, and June 2021. From the study results, it was found that the average percentage value for load imbalance in KM Pulau Pinang on March 12, was 15.73% with an average electric current value of 8 Amperes in the neutral conductor. On April 7, the average percentage of unbalanced load sharing was 23.42% with an average neutral current of 12.26 Amperes. On June 19, the average percentage of unbalanced load sharing was 16.02% with an average neutral current of 6.11 Amperes.This research can provide new information regarding the study of load sharing imbalance and electric current in 3-phase electrical installations on fishing vessels. It can also serve as an evaluation for ship owners in reducing power losses due to the emergence of electric currents in the neutral conductor

ANALISA PERPINDAHAN PANAS HEAT EXCHANGER MESIN INDUK (STUDI KASUS: KM. SUMBER MUTIARA)

Heat exchanger (HE) is a component of the main engine cooling system that plays a very important role in the process of changing the fluid temperature by exchanging the amount of heat with other fluids. The use of HE in the main engine cooling system should be considered in controlling after operation. HE performance can be analyzed using heat transfer analysis in the form of heat absorbed by HE (Q), LMTD and heat transfer coefficient (U). This study aims to analyze heat transfer in the form of calculations of absorbed heat, LMTD and heat transfer coefficient on the main engine HE KM Sumber Mutiara. This study measures the temperatures of fresh water and sea water entering and leaving the HE. In addition, measurement of water discharge and determination of the dimensions of the HE used for the main engine cooling system of KM Sumber Mutiara. This research shows that the highest heat value absorbed by HE (Q) is at RPM 1200 at 44.85 kJ/s, for the LMTD value at RPM 1000 at 45.69 oC and for the U value at RPM 1100 at 824 W/m2. oC. HE main engine KM Sumber Mutiara has not maximized its performance due to the fouling factor from sea water.
