<![CDATA[This paper focuses on the effect of the new method on the crystallite size and thermal stability of Fe80Cr20 alloy powder. Generally, the ball milling sample and ultrasonic technique sample have dissatisfaction result when applied at high temperature. In addition, the combination of both techniques not yet carried out. Therefore, this study aim to investigate an appropriate technique to produce smallest crystallite size in order to improve the thermal stability. The new method of mechanical alloying (mill) and ultrasonic technique (UT) were applied in order to reduce the crystallite size and improve thermal stability. The new method is called as combination treatment. This condition allows the enhancement of thermal stability of Fe80Cr20 alloy powder. In this study, mechanical alloying process was carried out by milling time of 60 hours. Then, the ultrasonic technique was performed at frequency of 35 kHz at 3, 3.5, 4, 4.5, and 5 hours. From XRD analysis, it was found that the broader peaks indicated the smaller crystallite size. It shows that the combination treatment (milled and UT) reduce the crystallite size up to 2.171 nm when mechanically alloyed for 60 hours (milled 60 h) and followed by ultrasonic treatment for 4.5 hours (UT 4.5 h). Smallest crystallite size enhance the thermal stability up to 12.7 mg which shown by TGA analysis during 1100 0C temperature operation. The combination treatment is method which is effective to fabricate Fe80Cr20 alloy powder.]]>

<![CDATA[Particle size and hardness of Al-10%wt.Ti powders due to the influence of ball diameter have been carried out using mechanical alloying techniques. The milling device used consisted of a Fritsch Pulverisette-5 planetary type ball mill with the rotational speed of about 360 rpm and balls size of 10, 15 and 20 mm. The materials used are stearic acid which was used as a process control agent, aluminum and titanium powders. A mixture of aluminum and titanium powders has the composition of Al-10wt.%Ti. The Al-10wt.%Ti powders, stearic acid and stainless-steel balls were added to the Fritsch Pulverisette-5 planetary in the argon gas environment. The weight ratio of stainless steel balls to the Al-10wt.%Ti powder was 20 : 1. The mixing time process was carried out for 5, 10, 15, 20 and 30 hours, respectively. Changes in phase compositions of these Al-Ti powders under different ball mill sizes were examined by XRD, and the optimum experimental parameter was obtained: the ball mill size was 20 mm. It was found that from the diffraction patterns of the Al-10wt.%Ti powders, the peaks of titanium begin to disappear with the increasing of the milling time, which indicates the increasing degrees of alloying of titanium atoms in the aluminum matrix. The microhardness test results showed that the hardness increases with increasing ball size.]]>

<![CDATA[The need of coconuts in Indonesia is relatively high. The use of large quantities of coconuts produces large amounts of organic waste from coco fiber, which tends to become waste if it is not used to be beneficial for humans.One of the potential uses of coconut fiber is as a reinforcement of natural fibers in polymer matrix composite materials. Recently, the applications of composite materials have been expanded widely including structural angine component which whitstand certain load like impact load. But most of them used synthetic fiber. Although the use of natural fibers as reinforcement in composite materials has been widely studied, their use is still limited because natural fibers have their own advantages and disadvantages. The purpose of this study was to measure the impact strength of specimens of coconut fiber reinforced polymer matrix composite material, and to determine the effect of the length and concentration of coconut fiber on its impact strength. A significant and valid regression model was also generated in this research, that states the relationship between fiber length and fiber content of resin matrix composite material to its impact strength. The result shows that the impact strength of the samples were influenced by fiber content and fiber length. The regression models for the impact strength of resin composite reinforced with coconut fiber is Y = 4.44 +0.180 X1 – 0.52 X2 Where: Y = Impact Strength (kJ/m2), and X1= Fiber length (mm), and X2= Fiber content (%).]]>

<![CDATA[The use of diesel engines for vehicle applications has expanded for decades. However, it produces black smoke in the form of particulate matter contains fine and invisible particles during operation. The popular method for measuring the smoke opacity is by using a smoke meter for its simplicity and less costly. Fuel injection pressure is one of the parameters that affect the emission significantly, and the proper nozzle adjustment can reduce the density of exhaust gases and improve the engine performance. The purpose of this study is to determine the optimum fuel spray pressure that produces the lowest opacity value and analyse the effect of fuel spray pressure on the opacity value at a different engine speed. The present experiment uses the Hyundai D4BB engine, and the pressure variations were implemented on the injector nozzle at 125, 130, and 135 kg/cm2. The engine was also tested with various engine idle speed, i.e., 1000, 1500, 2000, and 2500 rpm. It has been found that the optimum distance of fuel spraying is 147.679 mm with injector nozzle pressure 130 kg/cm2, and the value of opacity is 9.51%.]]>

<![CDATA[Ejector pin in the mould is used to release (eject) the finished product, to vent gas out of the cavity and to expedite the material flow. It must have high strength, good hardness, good wear and corrosion resistance to withstand high pressure. Poor ejector pin may result in defect of finished product and delay the process due to additional time was required to release sticking product in the mould. The aim of this research is to select proper material for the ejector pin and analyse it not to experience plastic deformation. Three specimens’ steel was considered for making the pin, SUS 304, normal SKS 3 and heat treated SKS 3. Hardness and tensile test were used to examine the mechanical properties of specimens and impact was utilized to obtain impact energy using Charpy method. Static stress analysis was also used to simulate the working load using SolidWorks. Rockwell hardness test recorded that SUS 304, normal SKS 3 and heat treated SKS have 23.2 HRC 9.6 HRC and 38.03 HRC, respectively. Tensile test produced yield strength of 452.9 MPa for SUS 304 and 432.6 MPa for SKS 3. Impact energy absorbed during Charpy test for SUS 304 equal to 0,804 J/ mm2 and specimen SKS 3 equal to 0,863 J/mm2. By taking the mechanical test result and SolidWorks simulation, it was concluded that the suitable material for ejector pin is SUS 304.]]>
