Abstract

In this modern era the plastic waste is a waste that is very difficult to recycle because thedecompotion of waste plastic is very difficult, and also the decompotion of waste plastic need a longtime. There are many types of plastic that we use everyday such as plastic bag for food or for bring acup of tea and etc with cheaper price and you can get the pastic bag in every shop or minimarket inIndonesia makes the plastic waste is the most waste produced from house hold and the others.Therefore we need some ways or method to reduce the plastic waste by making a crusher plasticmachine. There are many materials used to make crusher plastic machine. Start from frame ofmachine and stand frame of diesel motor are use U profile with material ASTM A36. ST42 are usedfor tub crusher, pulley, 2 fly wheel, stand of knife, fly wheel cover, top hopper, bottom hopper. ASTMA36 material is used for key of spindle. HSS material is used for knife crusher plastic machine. 3 Vbeltwith rubber canvas material is used for move spindle crusher plastic machine. The method usedto make this machine is reverse engineering which is compare to another crusher plastic machinethat has been sold in. The advantages from this machine is cheaper than another cursher plasticmachine in market, have low power, can slice or crush plastic until 50 kg/h, and dimension of plasticthat has been sliced is 16 mm or 1,6 cm wich is smaller and smoother than another crusher plasticmachine in market. Type of the plastic that can be sliced by using this machine is polypropylenebecause polypropylene has more benefit in economic. The price of polypropylene which sliced ismore expensive than the other type of plastic and the knife of this machine will blunt faster if slicingor crushing another type of plastic

Abstract

Pressure vessel production process often experiences problems, one of problems is changing data sheet from customer, in this case pressure vessel is already in the fabrication process. Changes data sheet are found in external pressure which is 3.5 kg/cm2g from previous 1 kg/cm2g, then recalculation must be carried out refers to ASME BPVC Section VIII Division 1. Then stress analysis is carried out with FEM through Ansys software simulation to determine loading conditions on pressure vessel design. Then fatigue life analysis was carried out to determine value of usage factor. Calculation of new external design pressure, was found that MAEP condition in shell is 0.158 MPa, this value is less than external design pressure of 0.34 MPa. Calculation results show that pressure vessel must be installed with a stiffener ring. Two stiffener rings are designed circumferentially on the outside of shell. Then results of stress analysis show that highest stress value is located on head. This value is still below maximum allowable stress value for material head, which is 138 MPa and results of fatigue life analysis show that usage factor value is less than one, thus pressure vessel there is no fatigue failure during thespecified age.

Abstract

Lift aircraft are an important part of the fabrication industry so they become more efficient in terms of time and power. In a fabrication industry the manufacture of C canals the buildup process is still done manually with two people. So that there is a need for a lift aircraft to facilitate the preparation of C canals with dimensions of 45 cm x 49 cm x 600 cm or a total weight of 900 kg to be more efficient. The method used in the manufacture of this machine concept is ulrich method and then continued by analyzing the calculation of the engine and skeletal analysis. The analysis was conducted on this study using Fusion 360 software. The planning results were obtained by the conveyor engine using a 0.75 kW electric motor and using a 6.78 Nm stepper motor for rack gear shafts. The material used for the frame is the ASTM A36 and for the shaft is S45C. The result of the analysis on the upper frame is 44.93 MPa, for the lower frame is 48.09 MPa and for the towing profile is 39.26 MPa. The total cost for the manufacture of auto stacking machines is obtained from the calculation of rawmaterial costs and manufacturing costs. At the cost of raw materials making this machine amounted to Rp 99,062,000, while for manufacturing costs amounting to Rp 5,610,000. So that the total cost for manufacturing amounted to Rp 104,672,000.

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.

Abstract

The demand for heavy equipment is rising alongside industrial growth. The 120-ton Lowbed Trailer Dolly, owned by CV. XYZ, is commonly used for transporting heavy loads. Its chassis structure is crucial for supporting the truck and cargo. Structural analysis can help determine the strength and critical points with the highest stress, as well as the necessary structural stability to withstand the applied load. To understand the stress distribution and loading conditions, theoretical calculations were performed for comparison, along with 3D modeling using two types of beams: flat and arch. Furthermore, finite element analysis was conducted using Fusion 360 software (Education License). Theoritical calculation had a stress of 149.74 MPa and the stress analysis showed the flat-type beam had a stress of 168.925 MPa (below the maximum allowable stress of 233.33 MPa), while the arch-type beam had 267.097 MPa (exceeding the maximum allowable stress). Thus, the flat-type model is considered safe for a 120ton load. The percentage error between theoretical calculations and simulation results is 11.39% for flat-type and 43.49% for arch-type models.
