Study on the Effect of Post Weld Heat Treatment (PWHT) Time on the Tensile Strength and Hardness of TIG Weld Joint of Motorcycle Crankcase
No full textPostweld heat treatment (PWHT) is a common practice among building codes to reduce the residual stress, improve the ductility, and decrease the defects. This article describes the welding joint property of motorcycle crankcase material by taking tungsten inert gas (TIG) welding measures before PWHT on 200°C with holding time of 0,4,6, 8 hours. Test data were analyzed in relation to tensile strength, hardness and microstructure on the welding joint. The regions corresponding to the base metal (BM) and heat-affected zone (HAZ) were studied. The effect of holding time under PWHT on properties of joints can be investigated. The results demonstrated that micro-hardness in the weld and tensile strength decreased with PWHT time prolonging, while tensile strength increased with the extension of PWHT time. The microstructure before PWHT was coarse in the joint. With the extension of holding time under PWHT, the structure obtains fine grain and the characteristic becomes obvious
Tube Bending Machine for Home Industry Scale
No full textTube bending is a general term for the process of forming metals used to form pipes or tubes permanently. By utilizing plastic deformation, straight objects are bent to form arches. Metal pipes in the form of arches can be used as a connection to machine construction, circular ladders, bicycle frames, motor frames, furniture, musical instruments. To improve time and energy efficiency in the bending process, a roll bending machine is designed. This machine is also expected to meet the needs of buckling pipes so that it can be used as a business field by the community. This machine can bend pipes 3/4 inch to 1 inch with a thickness of 1 mm

The Blueprint of AWOS Implementation for Aviation Services at BMKG
No full textWeather is very critical for aviation. Especially regarding safety in air transportation. Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) in its duties and functions provides aviation weather information, conducts the latest weather observation activities for the needs of takeoff and landing at airports. The World Meteorological Organization (WMO) has targeted automation with a target achievement in 2017. But currently in conducting the latest weather observations, BMKG still uses conventional weather observation systems even though at some airports Automated Weather Observing Systems (AWOS) have been installed. The automated weather observing system is still not fully implemented yet. This study aims to create a blueprint for the implementation of automatic weather observations for aviation services within the BMKG. Guidelines for making blueprint use the Enterprise Architecture Planning (EAP) framework. EAP defines business and architectural needs related to data, applications, and technology needed to implement automation. The final results achieved are in the form of a blueprint for the implementation of automated weather observing system for aviation services within the BMKG which can be a guide for BMKG in achieving the vision related to aviation weather services
Predicting Stress Intensity Factor (KI) of Single Edge Crack Using Displacement Extrapolation Method
No full textCracks that occur in the structure will be very dangerous if left alone. Cracks can propagate and will eventually cause the structure to fail. Cracks that occur will cause singularity at the end of the crack, and the stress level is very high or reaches without limit (infinity). Stress intensity factor (SIF) is used to determine behavior of structures with crack. One of method that can predict SIF is displacement extrapolation method. Displacement extrapolation methods predict SIF by nodal displacement near end of crack. This research is to predict SIF of a thin plate with a single edge crack of 1.27 mm. The crack mode used in this research is mode I (opening mode) with a tension stress of 60 MPa. Nodal displacement for calculating SIF is taken from result of analyzing the cracked model using Patran / nastran. SIF prediction result from displacement extrapolation then to be compared with the results of analytical calculation
