Abstract

The torque of the DC motor needs to be known to determine the maximum load that can be exerted at a given speed. Torque measurement can be done with a dynamometer. The dynamometer uses the Prony Brake type, which uses the principle of frictional force to provide a load on the motor. The application of frictional force uses brake capillary load to produce a dynamometer with the Prony Brake type that is simple in manufacture and testing but reliable and accurate in making measurements. In the Prony Brake dynamometer, there are usually two pieces of wood used as a link between the motor and the torque arm; at the end of the torque arm, there is a ballast whose ballast value is multiplied by the length of the arm to produce the torque value of the DC motor. The results of the trials that have been carried out are that the reading results of RPM sensors, weight sensors, and voltage sensors have a deviation of less than 2%, and the current sensor readings have a deviation of less than 5%. The Prony Brake dynamometer that has been made can read the maximum torque value with a deviation of about 2% from the existing data.

Abstract

This research was conducted to analyze and determine service quality and supporting attributes and to find gaps or discrepancies between consumer expectations and perceptions to improve service quality and provide solutions to existing problems. Analysis of service quality is carried out using the Servqual Method (Service Quality), a method used to measure service quality. This Servqual method measures how well a service provided by a company/service is expected to be received. This Servqual method includes 5 Gaps with five attribute dimensions: Tangibles, Responsiveness, Assurance, Reliability, and Empathy. The data needed to analyze is by distributing questionnaires to customers and management. The results of distributing questionnaires to 27 respondents and the results of the analysis show that there is a gap between consumer expectations and the perceptions received. The most significant gap is in Gap 5 with the PS2 attribute -1.073, with repair solutions ensuring consumers are comfortable by inviting them to choose a comfortable seat. Gap 1 is on the TS1 attribute -0.215, so a solution is provided to ensure the cleanliness of the salon equipment used. Gap 2 is on the PS3 attribute -0.67 and is given a solution namely, staff must rearrange management service standards and ensure staff responds well to customers. Gap 3 on AS4 attributes -0.73 with improvement solutions, namely rearranging good service standards so that the advertisements promoted are appropriate, gap 4 there are two attributes that are not managed to fulfill, namely TS5 and TS6 so that suggestions for improvements were given to install automatic air fresheners in every corner of the room and look for the best internet network provider and increase internet network speed.
