Abstract

The home industry business of cassava chips on Jogonalan, Klaten was using the manual tools in the process of slicing raw cassava. The cassava cutting machine was an alternative solution for the businessman to increase productivity in the process of producing cassava chips. This machine functions as a cassava cutting in the raw material for making chips. The purpose of this design is to plan a cassava cutting machine with a safe and efficient construction in its application. The machine design method refers to the Pahl and Beitz concept. The planning and design process into the following main phases: Planning and task clarification, conceptual design, embodiment design, and detail design. Analysis of the motion mechanism and calculation of engine elements were used to determine the power specification and capacity of the machine. The planned capacity of the cassava cutting machine is 80kg/hour with a motor power of 0.25 hp, the final rotation of 210 rpm. The results of the technical analysis on the main part of the cassava cutting show that the power capacity of the electric motor, transmission system and frame construction on the machine was safe.

Abstract

The growth of the automotive industry has made the market demand for motor vehicle spare parts soar, especially motorcycles, including the demand for cylinder blocks. Procedure of this research was carried out to analyze the product of 4 stroke motor cylinder block castings, which include; manufacture of casting product designs, manufacture of gating systems and riser systems. Results and Discussion based on the results of the shrinkage simulation test that has been carried out through the type of sand casting casting with the casting material, namely FCD-600-3 cast iron (1290oC) and the impression material used is silica sand (20oC) with a gravity casting type of casting, it can be concluded  that the results of design testing 1 (one) obtained a filling velocity of 1.111 m/s, with a filling time of 3.8 seconds and a required solidification time of 6 minutes.  In design 1 (one) there is a shrinkage defect due to shrinkage located on the sprue and riser of 0.336%.  While the test results from design 2 (two) obtained a filling velocity of 1.09 m/s, with a filling time of 3.9 seconds and a required solidification time of 5 minutes.  In design 2 (two) there is a shrinkage defect due to shrinkage located on the riser and in the cast product of 0.404%.  The conclusion of the test results on both designs, it was found that design 1 (one) is the most optimal design for cylinder block casting planning.
