Developing ergonomics-based practice system to improve students’ typing skills

Abstract

Increased competence must exist in vocational education. Less measurability of competency typing and convenience in using the computer laboratory becomes a problem for the Department of Business Administration, Bali State Polytechnic. For that, we need a system repair work practice typing on the student. This research was conducted at the Department of Business Administration computer laboratory Bali State Polytechnic. The method used is experiment with design group within - treatment (same subject). A total sample of 28 students of the 2nd semester and are taking practice typing. Competence is measured from the speed and accuracy in typing. Comfortable measured by questionnaires of practice comfort, and fatigue measured using a 30 item questionnaire of fatigue. Data of fatigue and comfortable were analyzed using the non-parametric Wilcoxon test and data of typed competence analyzed using t- paired test at the 95% significance level. Results of this research showed that there was a decrease in fatigue student practice 28.10%, decrease in musculoskeletal complaints 31.14%, increase in comfortable 39.63%, increase in typing speed competence the 27.31%, and an increase in typing accuracy competence 5, 10%. It was concluded that the improvement of work practices system can reduce fatigue and musculoskeletal complaints of students and increase typing comfort and competence of students in the Department of Business Administration Bali State Polytechnic.

Ergonomic tetrapod reduces the MSDs risk and productivity of steel-bar assembly for reinforcement concrete beams

“…The type of activity performed was consistently found to be a major predictor of the frequency of work time spent in awkward postures for the trunk, legs, and arms (Forde & Buchholz, 2004). Those research showed that the construction industry has a high risk of ergonomic hazards that can lead to various health complaints, one of which is musculoskeletal disorders (MSDs) (Albers et al, 2005;Ferguson et al, 2012;Kasiani & Yusuf, 2019).…”

Risk Analysis of Upper Limb Musculoskeletal Disorders in Industrial Skin Measurement Workers Using the Assessment of Repetitive Task Method

“…Taking a break enables you to recover mentally when handling issues at work [8,17]. Therefore, work can be more concentrated, thereby reducing work errors and increasing work productivity [18][19][20]. c) Stretching muscles before and after work.…”

Eco-design of an air conditioning system decrease in carbon footprint

“…Emissions from transportation are significant, reaching 429,124.3 tons of carbon dioxide (CO2) equivalent for the 4,500 units produced annually. In relation to the use of the cold system, carbon dioxide emissions (CO2) for the total of 4,500 units in annual operation is 2,812,320.0 Tons of CO2 equivalent considering 8 hours per day for 20 days and 365 days anus (Kasiani & Yusuf, 2019;Omer, 2015). The carbon footprint for the 12,000 BTU capacity air conditioning Functional Unit is 722.88 Tons of CO2 equivalent per year.…”
