Abstract

Shredding is one of the common recycling methods used for plastic waste processing. Along with the development of the era, conventional tools have begun to change to semi-automatic. Therefore, a shredding machine is needed for plastic waste processing with an automatic sensor system to facilitate operation. This design aims to determine the performance of a PET plastic shredding machine with the shredder shredding method. Pahl and Beitz is the method used in making this tool. In accordance with the method applied, the manufacture of the tool starts from planning, concept design, shape design, detailed design, documentation creation and realization of the tool. The testing process is carried out by testing the function of the machine and the function of the automatic sensor. The designed shredder machine has the following specifications: Dimensions of the tool are 950 x 365 x 1060 mm, capacity is 20 kg/hour, 3 phase ½ HP dynamo motor, rotation speed is 70 rpm, number of blades is 14 and material used on the blade is AISI 1080. The test results of this tool show that the tool can work to shred PET plastic, can shred 1 kg of plastic bottles in 2 minutes 45 seconds, the first shredded result is 150 mm maximum smallest size is 16 mm with 3 shredding processes, and can be operated with a sensor control system for the tool's work process. Keywords: shredding machine, garbage, plastic

Abstract

Aluminium Alloy 6061 merupakan jenis Aluminium seri 6xxx yang memiliki sifat mekanik baik seperti ketahanan lelah, keuletan, ringan, mampu mesin, dan kemampuan bentuk yang tinggi. Akan tetapi, Aluminium Alloy memiliki kelemahan dari segi kekuatan yang lebih rendah jika dibandingkan dengan Aluminium seri 2xxx dan 7xxx. Sehingga dapat dioptimalkan, salah satunya melalui proses perlakuan panas T6. Proses ini dimulai dengan tahap solution treatment pada suhu 540°C selama 1 jam dan quenching menggunakan air. Selanjutnya, dilakukan artificial aging pada suhu 165°C dengan variasi waktu penahanan 1 jam, 3 jam, 5 jam, dan 7 jam. Penelitian ini bertujuan untuk mengamati perubahan kekuatan dan kekerasan Aluminium Alloy 6061 sebelum dan setelah age hardening. Hasil penelitian menunjukkan bahwa kekuatan tarik dan kekerasan optimum tercapai pada waktu penahanan 5 jam, dengan kekuatan tarik 293,9 MPa dan kekerasan 109 HV. Namun, pada penahanan 7 jam, kekuatan tarik menurun menjadi 727,2 MPa dan kekerasan menjadi 70,2 HV.

Abstract

Finite element numerical simulation (FEA) has a function to analyze the design model and as a validation of the analysis results against manual calculations. FEA simulation uses specialized software to save time and cost. The purpose of the FEA simulation on this design model is to analyze the strength of the design model against a deformation. In this study, a strength test will be carried out on one of the sub-assemblies on the fishing equipment tensile and compressive testing machine, namely the fishing tools holder sub-assembly. The reason for the simulation is that the sub-assembly is directly related to compressive or tensile forces with relatively large units. The material used for this sub-assembly design is SS400 material or ASTM A36 Carbon Steel. The simulation process was carried out in 10 iterations using the curvature-based mesh method with mesh size settings of 10, 9, 8, 7, 6, 5.8, 5.6, 5.4, 5.2, and 5. The maximum stresses that occurred and reached convergence were at mesh sizes 5.8, 5.6, 5.4, and 5.2 in sequence with stress values of 137 MPa, 136 MPa, 142 MPa, and 135.7 MPa, respectively. The finite element analysis results show that the fishing tools holder design produces a maximum stress of 142 MPa at the converging area, with a factor of safety (FoS) of 1.8. Based on these simulations, the design of the fishing tools holder can be implemented on the Fishing Equipments Tensile Test and Press Test Machine.
