Abstract

This study aimed to develop learning media of pneumatic systems based on computer-assisted learning as an effort to improve the competence of students at the Department of Mechanical Engineering, Faculty of Engineering UNESA. The development method referred to the 4D model design of Thiagarajan comprising the steps of: define, design, develop, and desseminate. The results showed that the expert validation average score included in both categories was 3.54, indicating the learning application acceptable. A limited test showed effective results, namely: (a) Analysis of the data included in the category of learning was good (3.64), indicated by students’ enthusiasm in the learning process; (b) Teaching learning activities were categorized as good, the students actively involved in learning, and the most dominant activity was doing tasks while discussing; (c) Learning objectives were both achieved individually and classically; (d) The students showed a positive response expressed by the students’ interest, excitement, and motivation to follow the learning process.

Abstract

The heavy weight of the 3-axis router gantry arm and the high cost of manufacturing are the problems faced. The purpose of manufacturing is to obtain low weight and manufacturing costs. The method of manufacturing the router gantry arm includes: design of the arm with a width of 350, a height of 170 mm, a thickness of 12 mm; making a composite mold of the gantry arm measuring 350 × 170 × 12 mm from wood; preparation of 5 pieces of Aluminum pipes as reinforcement with a diameter of 6 mm, a length of 120 mm and 140 mm which are bent to the side in the router shaft section; composite molding with epoxy resin and aluminum pipe reinforcement arranged parallel with a distance of 30 mm from each other in an upright position, except for the position where the hole is bent to the side; making a Router shaft hole with a diameter of 20 mm and other binding holes with a diameter of 10 mm and 6 mm; and quality and dimension inspection. The manufacturing results are a router gantry arm with a width of 350, a height of 170 mm, a thickness of 12 mm with a weight of about 680 g or 44.90% lighter than solid aluminum material; The total manufacturing cost is IDR 108.125/unit, and the production process duration is 310 minutes/unit, which implies that the weight of the pole arm is reduced to around 55% compared to solid aluminum material and the price is cheaper by one-third.
