Abstract

This training aims to create an arduino robot that is controlled using android. The initial study of this research was to design a Proteus simulation to test the performance of robots. Next, design the robot by combining the motor driver, wheel engine and Arduino. Finally, integrate the robot with Android to control the robot's navigation system. This Android-based Arduino robot training will be introduced to students in the robotics workshop at SMP 11 Bandung as a medium for teaching physics or electronics. With this training, it is expected that students will be able to increase innovation and more creativity towards the subjects taught.

Abstract

Failure analysis to the economizer tube of boiler with operation pressure ± 190 bar, in holding time 6 hour gacor slot have been investigated. The economizer tube is carbon steel, ASTM A210 Grade C, outside diameter ± 51 mm and thickness ± 6 mm. The investigation cause of failure from the economizer tube included : chemical composition and metallography analysis, visual examination at outer and inner fire side, measuring thickness and densities of the scale at inner fire side and wall side, chemical composition analysis of the at surface crust the economizer tube. From the results of visual investigation to both outer and inner fire side of the economizer tube shown that at fire side occur decrease thickness gacor slot of the wall tube, with minimum thickness are 1.37 mm and 2,50 mm, respectively. Those caused by erosion corrosion result from effect the fly ash. Beside that, at inner fire side of the gacor slot economizer tube occur light pitting corrosion result by oxygen corrosion.Keywords : Economizer tube, boiler, fire side, fly ash, erosion corrosion, pitting corrosion, scale, oxygen
