<![CDATA[The Boiler is one of the equipment in the steam power plant which their reliability will be decreased by annually. Boiler degradation can be observed by the decreasing value of boiler efficiency every year. To maintain the efficiency it is necessary to know the main cause of degradation factors. PLTU Tanjung Jati B Unit 3 and 4 using pulverized coal fired boilers with forced circulation and sub-critical pressure type, the steam capacity is 2x2280 tons / hour to generate electrical energy of 2x660 MW.Boiler Efficiency is calculated by indirect method with uncertainty rate (0.4% -0.8%) in every boiler heat loss. The highest efficiency of boiler Unit 3 was achieved during Commercial Operation Date (COD) in 2011 with 89.71%, while Unit 4 achieved on the 2nd test performance in 2013 with 89.61%. The lowest boiler efficiency value for Unit 3 on the 9th performance test in 2016 with 88,36%, and Unit 4 was on 9th performance test in 2016 with to 87,48%. The degradation of Unit 3 boiler efficiency during 6 years is 1.35% or 0.225% per year. While the degradation of Unit 4 boiler efficiency during 6 years is 2.13% or 0.355% per year. The major of boiler heat loss were from exhaust gas (L1), moisture content of burning hydrogen in fuel (L3) and heat loss due to the moisture in the fuel (L2). The main factors losses in boiler is caused by ash deposits in the economizer area, it make inhibition of heat transfer from (flue gas) to economizer tube, the others from the use of three types of coal which have different characteristics.]]>

<![CDATA[Double Metal Arc Welding Gas Electrodes (DE-GMAW) is a new welding process that separates the melting current into a base metal current and a controlled current by adding a TIG torch to a conventional GMAW system to form an alternative path that will flow through the current. This makes it possible to reduce the current passing through the base metal, so that the heat input in the base metal can be controlled at the desired level. Research has been done to know the parameters for the welding process run stable between welding wire and torch TIG as current cutter. Parameters that affect the stability of the control system are Bypass Electrodes, Tungsten Distance to Welding Electrodes, Tungsten Distance to Workpieces, Torch GMAW Tube Distance to Workpieces, Angles between Tungsten and Welding Wires. To control the base metal current at the desired level, a group of power resistors is added in the control system. In this study, the welding is done using 18 V voltage by using several variations of the number of resistors. From the research shows that the control system developed can adjust the current cut in a large range to maintain the base metal current at the desired level. The welding results using the DE-GMAW control system show the physical properties of the weld result better when compared with welding without using current control system.]]>

<![CDATA[In Faculty of Industrial Technology Islamic University of Indonesia, whiteboards are used as a medium of learning in the classroom. Generally, instructors use non-permanent markers to make it easy to clean with an eraser. The problem that occurs is if this eraser is often used, the ability will decrease. This is caused by the large amount of ink markers that have been attached to the eraser cloth so that some ink that can not stick in the form of fine grains eventually falls and collects in the dirt container. These fine grains can contaminate clothes, hands, and other body parts. In addition, there are remnants of ink markers on the board that can hinder to write the next material. But to overcome this, there is a contradiction that is if an eraser is often used, the ability will decrease. To eliminate this contradiction, a systematic method of problem solving was used, namely TRIZ method. This method helps to provide solutions through the principle of preliminary action. This principle was realized by adding a spray mechanism that is used just before the erasing process is carried out. Testing the ability of the eraser was done on a whiteboard with ink markers with the size of 50 x 50 cm. The results show that the new eraser that has been developed is able to bind more ink markers and can completely erase so that it can write the next material clearly.]]>

<![CDATA[ Wire flame spray process is one of metal coating technique. The flame spray process is basically the spraying of molten metal onto a surface to provide a coating. Material in wire form is melted in a flame (oxy-acetylene flame most common) and atomized using compressed air to form a fine spray. When the spray contacts the prepared surface of a substrate material, the fine molten droplets rapidly solidify forming a coating. In this research, commercial steel wire (Fe-C), which has 1.25 mm in diameter, was used as raw material. The wire was heated and melted by two oxy-acetylene nozzles and then sprayed onto steel bar surface to form a coating. Vickers hardness testing and optical microscope were used to define the coating characteristic. The result shows that the coating has higher hardness number than the substrate material and the intrusion of carbon was founded in the coating microstucture.Keywords: coating process, wire flame spray, oxy-acetylene]]>
