ORGANIC WASTE CHOPPER TOOL DESIGN USING AUTODESK INVENTOR 2015 SOFTWARE

. In the program of mechanical engineering, the software used to draw is Autodesk Inventor. Autodesk inventor is a CAD program in the program of engineering that is applied to the design of mechanics in 3D. In designing a tool, of course, it is preceded by a planned design concept. In making a design a tool requires a process or steps for making the design. These steps include the size, dimensions, and materials used in making organic waste chopper tool. The drawing process uses the 2015 Autodesk Inventor program, the first is the making of sketches, components on the machine, followed by assembly of each component, then rendering images, animation as the final stages of drawing design input into "IDW" complete with size, scale, material. Image projection to make it easier for designers to make tools. Drawings of plan and complete details covering the scale dimensions will be able to simplify the manufacturing process (production) of the components of the tool and can reduce the risk of errors in the process of making tools.

takes into account the functions, aesthetics, data, thinking, brainstorming, and pre-existing designs. Design comes from several languages, one of which is the word "designo" (Italian) which grammatically means draw [7] [8].
Based on the description above, it is deemed necessary to know how to make the Design of Organic Waste Chopper Tool by using the 2015 Autodesk Inventor Software, and whether the design of the tools made can simplify the process. The purpose of this research is to be able to make the design of Organic Waste Chopper Tool by using 2015 Autodesk Inventor Software, as well as knowing the phase of design both in 3D, working drawings, assembly and animation methods.

CONCLUSION AND RECOMMENDATIONS 4.1 Conclusion
In making the design of the organic waste chopper design, the first is the design idea, then the drawing process using the 20 15 autodesk inventor program includes the making of sketches, component images from machine parts, followed by assembly, then rendering and animation. The final stage of the design is entered into "IDW" complete with size, scale, material, working dra wings so as to make it easier for designers to make tools. With the design drawings complete with working drawings (projections, scales and dimensions) can simplify the process of making components of the tool and can reduce the risk of errors in the process of making tools

Recommendation
In making the design, it is better to make the right size of equipment, especially between the hole and the shaft so that when the assembly process can blend easily. Each component size must take into consideration the ingredients on the market so that lat er in making the tools used the ingredients are easily available, and each component of the image must be as complete and clear as possible so that the reader is easy to understand
