Abstract – PT. Aneka Adhilogam Karya is a national private company engaged in the sand-casting industry supplying its products to the Perusahaan Daerah Air Minum (PDAM) Indonesia. One of the products of piping supporting components manufactured is Clamp Saddle. Many of these products still have casting defects, such as gas porosity and shrinkage. Gating system is one of the most crucial factors to determine the quality of cast products. It is necessary to design a gating system for Clamp Saddle products. Then the casting simulation using ProCast 2018 needs to be done to get an optimal design and detect the presence of defect shrinkage or gas porosity. Furthermore, the sand casting process is carried out, and radiographic testing is carried out to detect defects in the inside of the Clamp Saddle product. The results of the study obtained agating system design with a pattern size of 400 mm x 335 mm then analyzed defects using ProCast 2018 on the variable total shrinkage porosity and air entrainment so that optimal results were obtained. Clamp Saddle product results from sand casting experiments were tested using radiography test(RT) to detect shrinkage or gas porosity and found some gas porosity but were still tolerable because of their small size of about 1 mm then they were few in number and were not gathered together

Abstract

It can be known that in the efforts to maintain and repair the railway, especially in the process of replacing the old rail into a new rail, sometimes overall still using human power or conventional means. However, there are generally tools used for the rail change process. The tool used for rail change is with rail mover. The use of rail movers is limited to the removal of rails only, while for the transfer of rails from one place to another by transporting by human power. So that in the process of working on the rails become less efficient. In addition, it only has one hook block, meaning that in one operation it can only move one rail. With such conditions, researchers will conduct a rail mover product development. The design result obtained safety factor H Beam has a value of 9,985 , deformation value of H Beam of 0.093368 mm, top buckling support value 50,465 times and bottom support 176.94 times, pin shear stress value of 7,618 N/mm2, hydraulic pressure value of 636.97 N/cm2 and scissor able to lift weight 36,440.59 N at highest position and can lift load 9,739.42 N at lowest position. The need for the number of rail movers used in the operation of the lifting and moving of the railway is as much as 1 piece of rail mover. The total cost for the manufacture of rail movers is obtained from the calculation of raw material costs and manufacturing costs. In the cost of raw materials for the manufacture of rail mover is Rp15,678,427 while for manufacturing costs of Rp13,350,000.
