    Airbox system consist of filter element which greatly influenced the quality air into the engine system. The main objective of this study is to improve the performance of airbox system that attached in MODENAS CT115S engine system. Airbox, an empty air chamber, accumulates the outside air and feed it to the cylinder of the engine for combustion process and contains filter element. The function is to provide cleaner air for greater combustion rate and cleaner emission. The performance of airbox can be influenced by changing the location of the filter element and the geometry of airbox. By changing these parameters, the performance of the airbox system can be enhanced. In this study, the geometry of the airbox inlet has been changed in terms of shape and size. The inlet shape for Design 1 in round shape with a diameter of 43.60 mm. Meanwhile for Design 2, the geometry of airbox inlet was changed to a rectangular shape. Between these two designs, Design 1 provides a better result in terms of mass flow rate (10.41 kg/s), velocity (9.84 m/s) and pressure difference (83.44 kPa). By increasing the performance of airbox, the performance of engine can be increased.

    For centuries, the finite element (FE) method has been extensively used to predict the fracture performance and various method has been implemented to yield accurate results especially in healthcare industries. Bone fracture has been a critical problem since it interrupts the strength and structure of human bone. Thus, this problem will lead to bone malfunction and cause excess bleeding of surround tissues. Human bone consists of cortical and trabecular bone which serve a different amount of load sustainability before the fracture occurred. One of the most vital problems arise is the inaccuracy of the stress intensity factor related to the bone fracture. Recent studies have proven that with the implementation of appropriate meshing element produce higher accuracy results especially with the implementation of mesh refinement in the finite element model. The singularity elements suggested by Barsoum (1976) has proven that the quarter-point triangular elements give highly accurate results. Several methods for stress intensity factor calculation has been implemented by various past researchers. Among all the methods used, J-integral has proven to be the most accurate method compared to the others.The first section in your paper.
