INTRODUCTION Plastic is an item that humans commonly use as a material or tool daily because its benefit as easy to get, economical price, heat resistance, and lightweight. Plastic material is a type of polymer that has a permanent structure. In other words, the plastic refers to a specific type of polymer that includes a wide variety of polymer variations (Linda et al. , 2. Plastic seems to have become a necessity that must exist in society, although some people are unaware its bad impact on the environment when it is no longer used (Saila et al. , 2. The use of plastic in food packaging, beverage packaging, shopping bags, and other wrappers are some of the main sources of plastic waste generation today (Inggit Br Sitorus & Nanda, 2. Jurnal Dinamika Vokasional Teknik Mesin. Volume. 09 No. October 2. 180 The types of plastics include PET (Polyethylene Terephthalat. HDPE (High Density Polyethylen. PVC (Polyvinyl Chlorid. PP (Polypropylen. , and PS (Polystyren. (Haryono, 2. Of these several types of plastic, some plastics are often used by the community, namely PET plastic which is usually used in the manufacture of single-use plastic bottles. PET is a polymer produced from the dehydrated condensation of Ethylene Terephthalate, through the esterification process of terephthalic acid with Ethylene Glycol (Achidah et al. , 2. Because of its economical nature, the more plastic is used, the more plastic waste accumulates and is thrown carelessly, the plastic waste becomes difficult to decompose in the soil, causing environmental damage (Huzein & Hasballah, 2. Waste and other pollutants that are disposed of carelessly can cause serious environmental pollution, endangering human health and ecosystems (Achmad et al. , 2. According to the Indonesian Plastic Industry Association (INAPLAS) and the Central Statistics Agency (BPS) in 2022, the amount of plastic waste in Indonesia will reach 64 million tons per year (Nurhayani, 2. In the last ten years, the amount of plastic waste in Indonesia increased by 6% to 6 million tons in 2021, which is equivalent to about 17% of the total national waste. This means that each Indonesian people produce is around 0. 11 kilograms of plastic waste per day (Malihah et al. To overcome the accumulation of plastic waste that is increasing day by day, it can be overcome by recycling plastic waste. Recycling is the process of turning waste into new products while reducing the use of fresh raw materials, to produce more useful products (Rohima et al. , 2. Plastic waste recycling is included in one of the waste utilization programs, namely the 3R program which consists of Reduce. Reuse, and Recycle, this program is expected to reduce the environmental impact of waste management improvement (Hidayat et al. , 2. One of the plastic waste recycling technologies that can be done is the use of plastic shredding machines which are intended to process plastic waste into processed products that have a higher use value and sell higher by carrying out the waste recycling process. A plastic shredder is a waste recycling technology, or a tool used to chop or crush plastic into smaller pieces. The chopped products then can be used as recycled materials for entrepreneurs (Habib Almukti et al. , 2. Several studies have explained that plastic shredding machines have several types according to the cutting tools used, such as the shredder type which reel type of cutting tool that is usually used as a conventional lawn mower (Yudha Triadi et al. , 2. the scissor cutting type whose cutting tool has the smallest angle to facilitate chopping (Desi et al. , 2. Meanwhile, the design of this plastic shredder is an HSS crusher-type plastic shredder. This plastic shredding machine is a crusher-type machine or type used to damage the structure of the material and reduce its thickness so that it will be easier to chop. The results of the cutting were obtained in the form of small flakes (Nur, 2. The problem faced by the community is the management of plastic waste. People are still not aware of the importance of managing plastic waste which is difficult to decompose in the environment so if the waste is left alone, it can cause problems in the future. People's habit of throwing rubbish Jurnal Dinamika Vokasional Teknik Mesin. Volume. 09 No. October 2. 181 anywhere, such as on roadsides, gardens, and rivers, pollutes the environment. In this process, the plastic shredder plays a crucial role. This machine cuts or shreds plastic into smaller sizes, making the recycling process, such as melting and reshaping into new products, more manageable. However, most plastic shredders available today face various challenges. Some of these include high production costs, large energy consumption, limited capacity, and insufficient ability to shred different types of plastics effectively. Moreover, many machines are not designed with sustainability in mind, such as energy efficiency and ease of maintenance. Therefore, developing a more efficient, affordable, and environmentally friendly plastic shredder has become an urgent necessity. With an optimized plastic shredder, plastic waste management can be improved, helping to reduce environmental pollution while supporting a circular economy. METHOD This research went through several stages of completion starting from data collection, to supervision of the manufacture and testing of the plastic shredding machine, the design results can be seen in the following flow diagram. Figure 1. Flow Diagram The research method carried out begins with the collection of qualitative data with a literature study on the current plastic waste problem. With this data, a design of a plastic shredder design concept Jurnal Dinamika Vokasional Teknik Mesin. Volume. 09 No. October 2. 182 was made using Solidworks 2021 software. The design of the plastic waste shredder concept is made based on the data that has been collected. At this stage, the design concept that has been designed is then implemented in a more detailed three-dimensional form. This process results in a variety of components that, when combined, can form a complete and functional product. Furthermore, a design embodiment is made, which is a stage in the design process where the initial concept is realized in a more detailed or detailed form. At this stage, a complete drawing design along with the technical specifications of the tool will be produced. Designs that have gone through various stages then validated for design. The purpose of this stage is to ensure that the tool drawings prepared in the design stage meet the predetermined standards. This validation includes the suitability of the working drawings and the ease of reading so that the design can be passed on to the tool manufacturing stage. If there is a discrepancy in the design, it will return to the design embodiment stage. After the manufacture of the tool, a trial of the tool and an evaluation stage were carried out. RESULTS AND DISCUSSION The design of an HSS crusher-type plastic shredder was utilizing data from the literature studies. The design concept was produced after considering various aspects, such as recycling needs, material availability, and estimated costs required. This conceptualized design is then broken down into several Once the machine concept is designed, the next stage is to create an embodiment using CAD software, such as SolidWorks 2021, which includes the creation of 2D sketches, 3D models, and This stage ensures that every component of the machine is precisely designed before it is After that, the design validation of the HSS crusher-type plastic shredder was carried out with the final design that has been validated as indicated by Table 1.

The machine components consist of AS blade. US blade, side blade lock, side blade. UCP 208, size sieve. US knife holder, machine frame, output, holder. US cover, top cover, pulley cover, pulley, output cover, input, hopper, and machine wheel. The engine frame is made using UNP 50-60 iron. The drive of this engine comes from a 1HP electric motor. The machine comes from mild steel plate material which has 10 pcs of steel blades consisting of 6 pcs of steel blades and 4 pcs of sitting blades. When the electric motor is turned on, the small pulley on the electric motor will rotate forward to the large pulley on the engine by using a V-Belt with an outer diameter of 16 mm and an inner diameter of 11 mm, this transmission movement will rotate the AS connected to the chopping blade so that movement occurs. The PET plastic that is inserted through the shredder hole will directly enter the shredder which is secured by the filter component so that the plastic bottles that are inserted do not When the process has been carried out, the result is in the form of pieces of shredded PET plastic bottles that come out through the filter and then continue through the exit hole.
