Heavy Equipment

<p><em>Ruber Tyred Gantry (RTG) is heavy equipment for lifting containers from the jetty to the container stacking place or vice versa. It is found in all container terminals. RTG is almost the same as a Container Crane (CC) but its functions and movements are more dynamic. The CC is used on the jetty and attached to the edge of the jetty while RTG is more usable and efficient than other heavy equipment. Koja, Jakarta’s containers terminal has 25 RTG Units that operate and use a PLC (Programmable Logic Control) system for running the Spreaders, Gantries, Trolleys and Wheels as needed. RTG also capable of serving 5 to 6 lines in each block. The results of this study stated that the problems that occurred on the RTG includes: the burnout of the Gantry motor caused by the dirty motor, the broken twist lock that could cause collision between containers and also the lack of skill or understanding  of the RTG operator.</em></p><p><strong><em>Keywords:</em></strong><em> Containers, Spreaders, Twist lock</em></p><p> </p><p align="center"> </p><p><em>Ruber tyred Gantry (RTG) </em>adalah suatu alat berat yang terdapat di semua tempat terminal peti kemas yang berguna untuk mengangkat <em>Container</em> (peti kemas) dari dermaga ke tempat penumpukan <em>Container</em> atau sebaliknya.

Air Intake

This paper presents a study and investigation of an improvement of boiler efficiency with an automatic control of air quantity into a combustion chamber. A fire tube boiler with a fixed gate and screw conveyor for feeding fuel was used to test the automatic control system, and a sub-bituminous was used as a fuel for this study. The increase in boiler efficiency was based on controlling amount of air quantity for fuel combustion before entering to the combustion chamber using fuzzy logic control algorithm. Automatic combustion control was achieved by measuring the amount of Oxygen gas (O2) from flue gas stack. From the experimental results, it was indicated that the automatic control system can control the average amount of O2 in flue gas at 11.09% when the O2 in the flue gas was set at 10%. The boiler efficiency was increased by 4.34%, and the energy consumption was reduced to have a fuel saving of 195.88 ton/year.
