Abstract

Diesel engine is one type of piston motor fuel, whose fuel combustion occurs due to high air pressure in the combustion chamber. The combustion process diesel engine generates heat energy and raises the high pressure in the cylinder, the pressure is comverted to mechanical energy on the crankshaft. Then the cooling system is needed on the main engine. The cooling system is one system that functions to maintain the engine temperature at a certain temperature in accordance with the design specified so that the diesel engine can operate sustainably. This research work aims to find out how to work the ship’s cooling system, to find out how to maintain the ship’s cooling system, to find out the interference that occurs in the cooling system and to make repairs. The working of the cooling system at KM Sumber Fortuna use a cooling system indirectly / closed by using a heat excanger as a place to heat the heat excanger media by circulating fresh water to the entire machine to remove heat arising from combustion and friction in the engine. The method of maintenance is carried out with the duty service for 4 hours, the service carried ou is to check all the engine components in KM Sumber fortuna. While the damage occurred in the seawater suction pipe which had leaked in the pipe binder and replaced the leaked pipe by cutting the new pipe or hose and clamping the pipe / hose on the suction side of the heat exchanger.

Abstract

One of the safety factors in the world of railways is a reliable and excellent signaling system. Railway signaling consists of two components, namely electronic and mechanical parts, in the electronic part there are light signals with red, yellow and green indicators like traffic lights on the highway, for the mechanical part there is a wesel motor component that functions as a regulator of the direction of turn or rate of the train to be addressed, and for the signaling system used is the interlock system. Interlock is a relay-based device that functions to secure train travel and minimize train accidents. In 2009 there was an accident between Senja Utama Semarang train and Argo Bromo Anggrek train due to power outage and driver's negligence in reading signal lights. This research aims to design IoT-based automatic signaling on trains and automate train control to reduce the number of accidents. The train that will be used is a miniature train with HO scale 1:87 with a layout of 2 station lines and 1 non-station line, a servo motor is used as a turn signal, an IR sensor (FC-51) as a train detector and as a previous signal light colour changer, and a HUSKYLENS camera sensor as a signal light colour detector on an automatic train. In the interlock system using the Finite State Machine (FSM) method applied on the Arduino Mega, this system is monitored via a website. The train control system is applied on ESP32 and controlled through Blynk. The design of the signaling system and automatic train control has been able to achieve a 100% success rate with the implementation of an interlocking system with an average delivery time from ESP32 to the server is 2.779 seconds. Light signals, switches, and position sensors can be monitored directly through the website. Both automatic and manual train control can be controlled directly through the Blynk application.
