Development of Models Products-Based Learning Through Design of Learning Devices Using Oil Palm Empty Fruit Bunch (OPEFB) Fiber

To improve the competency of vocational education
graduates especially Diploma Three Mechanical Engineering who
have skills and readiness work is by the development of learning
models. To produce application products would require the
selection of products and learning tools that are effective and
efficient. OPEFB is a waste from POM which is still open wide to
be developed as Reinforcement in composite materials. To
achieve the objectives of this study required a OPEFB
decomposer machine. The design of the OPEFB decomposers
consists of the main components, namely the chopping knife, the
retaining knife, the parser, and the filter to produce the OPEFB
Fiber. The manufacturing technology chosen in the design of this
tool consists of several stages of work, namely cutting technology,
machining, forming, grafting, and assembling. The result of
experiment of capacity relation with efficiency shows that at 1200
rpm rotation is obtained 96,78%. Using a compound blade and
an optimum capture capacity based on the efficiency of 1200
rounds obtained 98.68 Kg/hour. From the whole series of tool
design activities in this research can be concluded that the
resulting tool is able to work optimally in producing OPEFB
fiber and can be used as a product-based learning tool.
