Abstract

The expansion of the market or need for satay skewers has resulted in micro, small and medium enterprises producing satay skewers, especially in Krasak Kualahan village, to meet consumer needs. In Krasak village, micro, small and medium businesses still use traditional methods to process bamboo into skewers. However, this method requires a long time. Therefore, this machine was created to help skewer production businesses speed up the production process. By making a skewer printing machine using Double Roll technology, it will help businesses to increase production results. Double Roll technology is a technology that utilizes two rolls that are close together to produce thrust. The way this skewer molding machine works is by inserting bamboo pieces 50mm wide and 0.8mm thick, 22 cm long between the rollers that coincide with each other. This machine has 2 knife functions, namely flattening and forming uses an AC electric motor as a driver with specifications 1Phase 1HP 1400RPM.

Abstract

The escalating volume of plastic waste has become a critical environmental challenge, highlighting the need for innovative solutions to repurpose it into valuable construction materials. This study aimed to design and develop a pneumatic-based eco-paving block printing machine that uses plastic waste as its primary raw material. The research methodology encompassed the design and simulation of pneumatic circuits, structural analysis involving stress distribution, displacement, and factor of safety (FOS), and strength testing of the fabricated eco-paving blocks. The machine was equipped with a pneumatic cylinder measuring 80 × 75 mm, operating at a pressure of 6 bar and generating a maximum pressing force of 300 kg. The simulation results confirmed that the maximum stress and displacement remained within safe limits, with a minimum FOS of 8.4, thereby ensuring a stable and reliable design. Testing of the eco-paving blocks revealed compressive strengths ranging from 38 to 54 MPa, surpassing the requirements of the SNI 03-0691-1996 standard. This study demonstrates that a pneumatic-based eco-paving block printing machine effectively transforms plastic waste into high-quality construction materials compliant with national standards, offering a practical solution to the plastic waste crisis while promoting sustainability in the construction industry.
