    DOI: 10.1088/1757-899X/879/1/012048

    Abstract

    The purpose of this research is to select suppliers of raw materials that will be used for production activities within the company. In this paper the method used was Analytic Hierarchy Process (AHP). This method is a method for solving a complex and unstructured situation into several components in a hierarchical arrangement, by giving a subjective value about the relative importance of each variable, and determining which variable has the highest priority to influence the outcome of the situation. The results are obtained from decomposition result or problem structure division in each hierarchy, then determining relative importance scale from each element based on pairwise comparison of each element in hierarchy, further calculating priority synthesis by doing multiplication process between local priority with criteria on hierarchy. Certainly, decision support result which obtain is very helpful for company to choose supplier, so that production process is running smoothly and customer demand can completed on time. © Published under licence by IOP Publishing Ltd.

  • Experimental Study Improving the Friction in the Surface of Cold Form Steel Connections Using Adhesive

    Experimental Study Improving the Friction in the Surface of Cold Form Steel Connections Using Adhesive

    Author: Setiyarto Y. D

    DOI: 10.1088/1757-899X/879/1/012169

    Abstract

    The purpose of this study is to test the strength of light steel joints using screws and the addition of adhesives to the surface of the joint. The addition of adhesive is done to increase the frictional force on the surface of the joint. The study was carried out experimentally by giving axial tensile strength to the specimens. The specimen is a mild steel connection made from a lip channel profile that is connected back to back with 2 screws and has 2 variables, namely adhesive and without adhesive. Each variable has 3 samples. The experimental results show that the addition of adhesives to the joint system is proven to increase friction. This shows that the joints that use adhesives have a greater strength of 17.20% than the joints without adhesives. The mechanism of collapse of the joint using adhesive starts from the collapse in the friction plane, then the screw undergoes tilting and subsequently experiences a collapse in the fused plane. From the results of this study it was concluded that the use of adhesives can be used as an alternative to increase the frictional force on the surface of the mild steel joints. © Published under licence by IOP Publishing Ltd.
