Abstract

Laboratories that meet ergonomic standards will support the learning process, both academically and technically, to facilitate the growth and development of skills. This study aims to uncover and provide an overview and information about laboratory ergonomics standards which include thermal comfort (temperature), workspace laboratory lighting. This study uses a quantitative approach with a survey method carried out in the Machine Tool Unit Laboratory of the Department of Mechanical Engineering Education with a population of 60 students who are carrying out practicum. Techniques using direct observation and measurement. Lux Meter to measure lighting and then Digital Thermometer which functions to measure temperature at the observation point in the laboratory. Data collection starting at 07.00 until 12.00 and in the afternoon starting from 13.00 to 16.00, which is the time to do work activities. Measurements made at ten observation points the results showed that; (1) thermal comfort (temperature) with a value of 30.44 degrees Celsius, while the ideal practical standard ranges from 24 – 27 degrees Celsius; (2) Lighting with a value of 422.14 Lux while the ideal practice standard ranges from 500 – 1000 Lux. These results indicate that there is a tendency for temperature and lighting in laboratory rooms under conditions that are less than the standard set. To increase work productivity, these factors can cause less concentration and stress at work.

Abstract

Someone will learn better if the person concerned understands his character in learning. Individuals in learning have various ways; some learn by listening, some learn by reading, and some learn by discovering. These diverse ways of learning by students are known as learning styles. Kolb's learning style is divided into four types, namely converge, assimilator, diverge, accommodator. The purpose of the study was to determine the profile of student learning styles of the Faculty of Engineering, Universitas Negeri Makassar, which is divided into 9 (nine) study programs. Samples taken with an error rate of 5 percent were 177 students. Purposive sampling is used as a sampling technique with special considerations so that it is feasible to be used as a sample. The research measures four types of learning styles, namely Active Experimentation (AE), Concrete Experience (CE), Reflective Observation (RO), and Abstract Conceptual (AC). The results showed that the accommodator learning style was more dominant in students. Of the eight majors that became the research subjects, seven tended to the accommodator learning style, and only one tended to the assimilator learning style. The accommodator learning style combines the poles of active experimentation (doing) and concrete experience (feeling). The use of learning methods following the learning style is Problem-Based Learning which involves all students in the learning process.
