Abstract

Occupational safety and health (OSH) is basically in the interest of all parties and is a basic right for workers. A safe and comfortable working process is an asset that is maintained continuously for quality and timely production. Work accidents are something that is highly avoided, work accident control must be carried out with methods that are in accordance with the field and industrial conditions. The purpose of the discussion in this paper is, how to control OSH in the fabrication industry in a sustainable manner, how to create good OSH regulations and make the production process safe and comfortable, how to form a good and professional work attitude. Work accidents that occur are actually the end result of a rule and unsafe working conditions. 85% of the causes of accidents are human factors. The fabrication industry carries out several processes such as welding, cutting, final processing and other supporting processes in the workshop. Recommendations have been made and implemented to reduce and control work accidents. The application of OSH in accordance with the concept of occupational health and safety management, theoretically the industry will be able to reduce the number of work accidents even to zero accidents from work accidents.

Abstract

Hydraulic press machine is a tool used for work that requires a compressive action force. The stress distribution that occurs in this study will be determined in the development of a press machine under a state of pressing with a load of 20 tons. Researchers use Finite Element Analysis (FEA) to generate data on the stress circulation in the engine construction. The research objectives: (1) Calculate the hydraulic pressure strength in theory, (2) Calculate the mechanical stress in the hydraulic press construction manually using the ANSYS R15.0 software, (3) Calculate the strength of the hydraulic press construction manually and using the ANSYS R15 software. .0. In this review, FEA estimation is completed with the help of Ansys Workbench R15.0 programming. The information load comes from hydraulic pressure. The inspection strategy utilizes FEA with the type of underlying structural analysis. FEA simulation results stated, the maximum stress that occurs in the table is 98.646 MPa and the maximum deformation is 0.21613 mm. The results of Ansys analysis stated that the maximum stress that occurs on the table is 98.646 MPa and the maximum deformation is 0.21613 mm. Considering the Tresca hypothesis, it is found that the stresses and deformations that occur are below the standard for structural failure. So that the frame of the hydraulic press is safe for use in a load of 20 tons.
