Abstract

Effective fuzzy front planning end in product development phase is very important steps to achieve successful product in the market. Success in ergonomics is not only determined by the design itself, but also by the time and cost incurred. Some of the contributing factors to the high cost of the product are lack of ergonomics skill of designer that lead to the trial and error nature of constructing the ergonomics product. Innovation ability of designer in small medium enterprise is often restricted by the fact that designer have lack knowledge of ergonomics. This difficulty can be reduced significantly with the application of concurrent engineering method supported by virtual prototype based CAD (computer aided design) and CAE (Computer Aided Ergonomics). We can integrate ergonomics with product design optimization and anthropometric parameter for suitable target market prior to production. Also we can anticipate all potential injuries caused by humanproduct interaction during use. Effective product planning is expected to contribute to lower production cost, to cross the innovation border, and boost up Company’s competitive advantage.

Abstract

Human circadian system causes employees on night shift are at risk of experiencing increased stress, increased workload. Additionally, they should face the consequences of different health condition compared to employees who work on a normal shift during the day. This paper discussed the size of stress levels of employees who work in a night shift system based on (1) workload and (2) health condition, as well as (3) employee’s biological, social, and psychological condition. Other studies have shown that support from company can help employees cope with stress. The support is like management facilities, such as support from supervisor to subordinate, and training support to improve necessary skills. Thus, besides the size of employee stress levels, this study also discusses the relation of company support as stress management. The result is a measurement model of stress level obtained based on Likert scale of 5. In this model, work shift stressors are measured by self-perception of self-satisfaction by the work shift. For occupational health perception, SF-36 is used to measure self-perception of health quality. As for the workload, the measurement of four resources at works using the scale of visuality, audiotory, cognitive, and psycomotor. The implication shows that this stressor measurement scales need to be tested to see the reliability and validity of the work environment in Indonesia, as well as to test the correlation between the variables used with management facilities received by employees.

Abstract

This study aims to test the hypothetical model that describes the correlation between motorcycling behavior and four latent variables assumed to make up bikers in action. A survey of 350 motorcyclists through purposive sampling was done by employing a research instrument. Validity and reliability test of research instrument were conducted by calculating the Cronbachs Alpha. Whereas, the hypothesis model test was conducted using statistical technique of Structural Equation Modeling (SEM) through Lisrel 8.72 software. CFI, Chi-square, and RMSEA are fit indexes used to test the suitability of the hypothesis model with field data (model fit). Structural Equation Modeling (SEM) and Confirmatory Factor Analysis (CFA) were used to evaluate the reliability and structural validity of the instrument used. Besides, they were used to test the hypothesis that a positive relationship between the observed variables and the four latent variables, as well as a positive relationship between the four latent variables and motorcycling behavior construct.
