Abstract

An activity of collaboration between Mechanical Engineering Department of Sanata Dharma University and SMK Nusantara Kudus was conducted. The percepetion of High School Students of SMK Nusantara Kudus about Computer Aided Design was measured during the Solidworks Training as the main activity. Pre- and Post-Questionnaires were delivered among the 20 students joining the activity. Nineteen of them returned the questionnaires of 10 positive statements with 3 conditions of answers i.e. agree, disagree, and undecided. The results show that the students mostly are interested in designing manually and computer based. It also mentions that they appreciate CAD skills as their important future work skill. The activity did not affect the interest of the students in term of designing but helped them to be more engaged to the CAD.

Abstract

This paper presents an explanation related to experimental testing in the form of the tensile properties of Al 6061. Al 6061 was heat treated by the precipitation hardening method. The precipitation hardening consisted of T4 and T6 treatment. Al 6061 samples were heat-treated at a temperature of 430°C for 2 hours, then cooled slowly at room temperature. The T4 was conducted at a temperature of 530°C for 2 hours, followed by rapid cooling in a water medium and natural ageing at a temperature of 70°C for six days. Temperature T6 is the final process of applying precipitation hardening treatment to Al 6061. Temperature T6 is carried out at 530°C for 2 hours, then cooled rapidly in a water medium and continued with artificial ageing at 190°C with a variation of ageing time for 3 hours, 5 hours, and 7 hours. The effect of the applied treatment was observed to increase the maximum strength value of the tensile test of Al 6061.
