Abstract

Paving block industries have emerged in the North Aceh Regency area, especially for the Baktiya District area where there are 7 paving block industries, which is due to the increasing demand for paving blocks of 1000 units per day in 2019 for office yards, parking lots, for pedestrian sidewalks and for parks. The compressive strength that can be accepted by paving blocks with PET plastic shredded substitution for each composition is as follows, in normal paving blocks (0%) of 11.32 MPa, in paving blocks with an addition of 0.3% of 12.31 MPa, in paving blocks with an addition of 0.4% of 12.70 MPa, in paving blocks with an addition of 0.5% of 14.55 MPa, and in paving blocks with an addition of 0.6% of 11.82 MPa. The percentage of the ability of paving blocks with PET plastic shredded substitution for each composition in absorbing water is as follows, in normal paving blocks (0%) it is 10%, in paving blocks with the addition of 0.3% it is 8%, in paving blocks with the addition of 0.4% it is 7%, in paving blocks with the addition of 0.5% it is 5%, and in paving blocks with the addition of 0.6% it is 9% Mpa.

Abstract

In the manual shredding process, the capacity is 50-70 kg/hour. Therefore, a crusher machine is needed to increase the capacity. The results of crushing the oil palm bunches can be used as compost. In this design, the cutting blade is designed with a larger number of cutting blades to accelerate the production of oil palm bunches so that it can operate optimally and does not require excessive power to move the tool because the tool designed will be driven using a gasoline engine and by adding cutting blades, the production capacity will increase. Design is one of the important things in making a program. The purpose of the design is to provide a clear and complete picture to the programmers and engineers involved. The design must be useful and easy to understand so that it is easy to use. Design is a process to define something that will be experienced in the process. The results of the machine test were able to produce a crushing capacity with a length of 3 - 14 cm, a width of 3 - 20 mm and ± 8.5 kg in one minute. The following is a systematic calculation of machine capacity: 1 minute = 8.5 kg per second 1 hour = 8.5 kg x 60 minutes = 510 kg/hour.
