Design and Development of A Single Page and Web-based Responsive E-learning System for Higher Education Institutions

Students now use not only computers or laptops, but also small devices such as mobile phones. The students at higher education institutions spent a lot of time on the internet to find the course materials. Sometimes the teacher sends the materials, but the students who are willing to take a specific course of a semester cannot get a brief concept of the course on before starting the semester. There is now a lot of online education systems on the Internet, but few are a single page and responsive. The purpose of this research is to develop a single page, responsive and web-based e-learning system. The method used in this research is the Rapid Application Development approach which has six stages of the development process, namely Planning, Analysis, Design, Implementation, Testing, and Maintenance. This research was conducted in the Faculty of Technology and Vocational Education, Universitas Pendidikan Indonesia. The students and teachers from the Department of Mechanical Engineering Education participated in this research. The results of this research indicate that with fully functional live chat, the OpenCourseWare system has a high usability test score, highly responsive and awesome features. The OpenCourseWare system is responsive and ajax-based mobile-friendly system that can be used by higher education institutions as an e-learning system based on the results obtained.

Comfort Temperature and Lighting Intensity: Ergonomics of Laboratory Room Machine Tools

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.
