Tug Boats Fuel Efficiency with use of Flow meter Web Based Monitoring and Control System in P.T. X

In order to increase efficiency, a monitoring system has been measuring operational performance existing. After a system created and used, management can measure performance to improve the efficiency. With all information that has been collected, management will be able to produce a decision accurately and increase productivity and efficiency operational. P.T. X has implemented the installation of flow meters in all ships and has been examined in previous research. It is continued deeper by applying the use of flow meters using web-based as a sensor long-distance, as to be monitored anytime and anywhere using a sensor equipment named eGenKit. For that, the study is conducted in order to assess the use of fuel efficiency on tug boats using web-based monitoring and controlling system in P.T. X.


Introduction
All the measurement of the flow of fuel is very important in management process of fuel in a ship. An instrument for measuring the flow called flow meter. This device serves determined to measure how much consumed during continuous ship operation. Fluid referred to fuel oil in a ship. The measurement of fuel intended for energy efficiency to manage and control the use of energy in their company. At the sea, energy sources for fuel must be managed, controlled and made more efficient. The cost of fuel is expenditure largest indispensable both on shipboard and in a building. Factors that have brought inefficiency fuel is: wrong design for ship (for example like the calculation size of propeller, machine, and others), a lack of competence crew especially that associated with operation and management, the theft of the fuel, and the quickness supervisory to support operational especially times in dealing with the problems. In order to increase efficiency, a monitoring system is used for measuring operational performance existing. After a system created and used, usually management can measure performance and take action anything to improve the efficiency. With all the information that has been collected, management is able to produce a decision accurately to increase productivity and efficiency operational. P.T. X has implemented the flow meters in all ships and has been examined in the previous research. From the previous research [3] P.T. X group is a company that moves in information technology, resources, energy, mining logistic & services. P.T. X group owned company shareholder in systems integration, ranging from Information Technology business process outsourcing/employment, services logistician/carting, business oil and coal mining. One of subsidiary of P.T. X is company services provided sea transportation that focuses on sea transportation including a barge intensity and ship for transporting coal, ranging from dredging, loading-unloading until transporting. One large project of that company has established cooperation with the government for transporting coal to nuclear power plant (PLN) in Pelabuhan Ratu, West Java. P.T. X has some tug boats, a small vessel assigned to pull or push larger vessels in port. Besides that, the tug also serves to draw barges contains coal coming from treatment coal plant to be brought to the port place then carried out to the trucks. Now the research is conducted much deeper applying the use of flowmeters using the internet use web based as a sensor remotely to be monitored anytime and anywhere using a sensor equipment named eGenKit. That is why the study is conducted to assess the fuel efficiency on tug boat using executive web-based monitoring and control system in P.T. X.

Problem Identification
The problems faced by P.T. X is: • How to select the type of flowmeter which is suitable for tug boat 2060 HP, in this case there are two tug boats i.e. tug boat Titan 21 and Titan 23, with great vary fluctuations rpm machine; • How to install and implicates the system and synchronize it with the existing fuel system; • How to monitor or analyze the use of flow meter with the objectives of installment the use of fuel in a ship. In this research, P.T. X developed the installation of flow meter with use of the web-based sensors that can be controlled the use of fuel anywhere and anytime by using eGenKit. Sensors set to be fitted in each of the ship are: --Fuel Consumption sensors 2 pieces those in the in-let and out-let, type sensors fuel-consumption is flow meters corilois owns by the Emerson, size 1/4 inch; --Bunker sensor 1 pieces to be installed in a pipe filling-bunker, type sensors bunker is flow-meter corilois owns by the Emerson, size 3 inch; --Rpm sensors 4 pieces, 2 in play engine (Main Engine) and 2 in Generator Set (Auxiliary Engine).

Types of flow meter [2]: ultrasonic flow meter, glass tube flow meter, turbine flow meter, electromagnetic flow meter, orifice flow meter. And the type fuel oil flow meter was the sub of glass tube flow meter is shown in Figure. 2. Flow meter discussed is the type rotary analog Aquametro brands [1] and type digital corilois Emerson brands. Flow meter type rotary analog Aqua metro brands used only on system discharging fuel and not to be used on system filling bunker. The use of satellite system is to report online flow meter type digital Coriolis Emerson brands on system discharging fuel and a filling bunker system.

Research Location
The object previous studies located on the island of Batam to the construction of ships that uses eGenKit. There are two ships i.e. tug boat Titan 21 and 23. After that observation and data processing brought from location where the tug boat sailing between port from Pelabuhan Ratu to Kotabani, Bengkulu.     Figure 5.

eGenKit Identification
eGenKit is a system based on monitor long-distance web-based and solutions to control and help the company make a decision accurately to optimize its operation. eGenKit consist of: a) panel localized (hardware) to be fitted on board, and b) server centralized (to store data and management). eGenKit does not require software which enables the user to have access to the ship all the time and anywhere. eGenKit uses transmission data hybrid between GPRS and satellite to produce a data transmission that costs cheaper and can cover revenue thoroughly.
