Abstract

Workload is crucial in managing and maintaining good performance of human resources and allocations. In an advanced manufacturing industry, human job functions had shifted to cognitive tasks. Thus, cognitive workload evaluation should be used to monitor worker’s workload in optimal condition. Most common tool of cognitive workload tools are perceived measurement, like NASA – TLX questionnaire. Despite of its sensitivity to capture workload felt by the workers, this subjective measurement was prone to bias. Objective measurement utilizing biometrics data of the human body during working state was useful to eliminate bias. Cardiac biometrics were one of the many that were closely related to mental activity changes. The objective of this study was to understand the relationship of cardiac biometrics to perceived workload as an indicator of cognitive workload analysis. The study utilized four biometrics, heart rate, HRV low frequency power, total frequency power and ratio of low and high frequency power, were used to analyzed a one hour long cognitive based study case. The study case was designed in a manufacturing planning context referring to manufacturing aptitude tests, to induce cognition process on 30 participants. The biometrics and NASA – TLX score result of all the participants, were then calculated as effect size standardization before input into random forest regressor model to analyze relationship between cardiac biometrics and perceived workload. The result found a moderate relationship between the two (r2 = 0.576). Features importance also showed the most impactful feature to the model is the effect size of frequency power ratio. However, it is recommended to always consider evaluating multiple cardiac biometrics in workload analysis to ensure good model performance.

Abstract

The focus of Industry 4.0 concept is to integrate production, information technology and the optimal usage of internet. It includes set of tools and applications that utilizing a smart embedded system of machines to perform a certain level of autonomous tasks in industrial system. The ideal infrastructure to perform such concept is remain a big challenge, especially for Small and Medium Enterprises (SMEs). In order to develop strategies which SMEs can get the maximum benefit from Industry 4.0, this study aims to measure their readiness level to adopt the concept. This study was conducted to fill the gap in such area of study, by adopting the “Industrie 4.0 Readiness model” by VDMA. Using survey and interview from 57 SMEs in Indonesia. Various data related with current state of knowledge and strategy implementation of Industry 4.0 were collected. The study concluded that most of the SMEs beyond the sample (56%) were still in the beginner level of adoption, 14% were even in the outsider level, and the rest of them still had no plan for the implementation. This data shows us that the implementation and adoption of Industry 4.0 in SMEs in Indonesia is still at the beginning, which need more attention from the policy and strategy maker to get to more mature level.

Abstract

Fatigue experienced by most of the public transport drivers cause a decrease in the level of vigilance while driving . The demands of the company or demands to be able to make ends meet cause most of the public bus drivers keep working even in conditions of fatigue so that the condition often causes accidents . To determine the level of awareness of the driver while driving is done by spreading the data collection questionnaire and use vigilance test software . Data obtained by using software vigilance test is Average Reaction Time ( ART ) . The data is then analyzed to see regression correlation relation to the number of variables which are , long drive , long breaks and the number of breaks . From the analysis it was concluded that the ART is directly proportional to the length of time driving or driving , but inversely proportional to the length and number of rest breaks , where the longer breaks and more breaks then the value of ART will be smaller .

Batik is one of Indonesian local wisdom, which not all of batik in Indonesia has a high popularity, such as Batik Malangan. Kansei Engineering method used in this study to identify the implicit desire of users in the form of feeling, emotion, or perception when interacting with Batik Malangan. By implementing the procedures Kansei Engineering Type I, there are 30 words that appear using 14 stimulants of Batik Malangan. Statistical data analysis performed using multivariate analysis. The most important kansei words chosen by using Factor Analysis and Principal Component Analysis. In this study, a total of 61 respondents who are citizens of Malang and from outside Malang participated. For customers, the main attraction at the Batik Malangan is the motive, whether the primary motive, secondary motive, nor the isen motive. Until now, Batik Malangan’s motive not yet have a characteristic, so it is less well known by customers. Overall, this study contributes to that Kansei Engineering is a method that can be used to capture the feeling of customers mainly on customized products. With so many product variations based on local wisdom should be able to be developed by actually capturing the customer's desire, not only explicit but also implicit.
