Abstract

In this work, an experimental study of a mechatronic system on control of airflow temperature has been conducted to identify the characteristics of the system. The system is tested by several reference temperatures from the monitor panel that programmed on the computer. The measurement of the output temperature by the sensor that is expected to be the same as the reference temperature is also displayed on the same monitor panel. While the measurement of AC power consumption by an actuator in the form of a heater is carried out by measuring the AC voltage on the heater during control. This voltage is measured with a computer-based oscilloscope. Based on the test results, with the initial temperature around the room temperature and reference temperature, the system time constant can be identified. This time constant value is obtained based on the output temperature graph which is identical to the first-order system response. Thus, this experimental study succeeded in identifying the characteristics of the system in the form of a time constant and the system was identified as identical to the first order system.

Abstract

In this study, the design of a wind tunnel was carried out to observe airflow through an airfoil, streamlines and turbine blades. To accommodate this, in this study a design was made of an open return wind tunnel. In this case, an open circuit wind tunnel type will be made because the construction is simpler and the manufacturing costs are relatively cheaper compared to the closed circuit wind tunnel type. The Wind Tunnel is designed with Open CLosed Wind Tunnel (OCWT) type. The OCWT is designed to consist of fan and housing, diffuser, test section, contraction, honeycomb. The OCWT design uses an operating fan to circulate air into the test section. The maximum air speed in the Test Section is 5 m/s with a flow that is closed to laminar. The recommended diffuser has a dimension of 50 cm on the side that is attached to the test section and 52 cm on the side facing the fan with an inclination angle of 1.79o. The driver uses a 16 inch exhaust fan with a power of 74 W to make the flow in the Test Section stable at a speed of 2 m/s.

Abstract

This study aims to identify and determine the level of consumer needs related to rice milling machine and, to develop a House of Quality (HOQ) to determine the dominant design requirements and the priority technical characteristics of the tool. The benefit of this research is to facilitate the design development so that it can continue to provide improvements to the quality of the rice grinder so that the quality of the rice produced can be maintained. The research method used is the Quality Function Deployment (QFD) method by conducting a survey to the field which aims to determine the level of consumer needs by distributing questionnaires and seeking information about what farmers need to make the farmer's work easier. Questionnaires were distributed to the community, most of whom work as farmers and workers in rice mills. The research location is in Pariaman Regency and Padang City. The results of this study are the highest priority scale from the aspect of consumer needs, namely fast work with a weight value (3.63) and from the technical response aspect, namely energy needs with a weight value (36.15). Based on the House of quality analysis, design development is focused on improving performance and optimizing energy sources using solar energy.
