Adjusting the production parameters to meet a specific target under such uncertainty can be time-consuming without the support of advanced simulation tools. Therefore, this research proposes a novel idea of facility layout and system simulation in mixed reality (MR) that facilitates production planning involving human operators. A production planning tool is implemented as an MR application to verify the feasibility of this idea using a test case of logistic facility design. In this case, a manager adjusts the current facility and production parameters designed for one product in order to operate the logistics of two different products that must achieve a given production target. An operator is responsible for manually sorting, transporting, and placing the products for storage. Both are participating in the system simulation as different role...

Industrial revolution 4.0 offers the convenience of digitizing so that computer access should be enjoyed by everyone. However, this does not apply to the physically disabled, especially the painters. The digital era pressured them to develop paintings with computers but are hampered by computer accessibility, especially pointers/cursors. This is the inspiration behind Difable Care (DC) mouse, which is designed like a slipper and connected to a computer via USB wireless. DC mouse features are the right-click, leftclick, scroll, and drag. The method consists of preparation, design, implementation, and evaluation. The prototype uses a 3D printing machine made from Acrylonitrile Butadiene Styrene (ABS) filament. The DC mouse is an accessibility solution for people with hand disabilities when operating computer pointers to increase painting productivity.

Using this technology, people can interact between virtual objects and the real world. Mixed reality has enormous potential for enhancing the human cyber-physical system for different manufacturing functions: planning, designing, production, monitoring, quality control, training, and maintenance. This study aims to understand the existing development of mixed reality technology in manufacturing by analysing patent publications from the InnovationQ-Plus database. Evaluations of trends in this developing technology have focused on qualitative literature reviews and insufficiently on patent technology analytics. Patents connected to mixed reality will be mapped to give technology experts a better grasp of present progress and insights for future technological development in the industry. Thus 709 patent publications are systematically identified and analysed to discover the technological trends. In addition, we map existing patent publications with manufacturing functions, and illustrate this with a technology function matrix. Finally, we identify future research in human cyber-physical system development by enhancing different human senses to give users more sensations while interacting with virtual objects. We provide insight into this human cyber-physical system development in three industries: automotive, food and beverage, and textiles.

Handwashing is kind of a clean and healthy lifestyle that is aimed to reduce the number of microbes in the hand. The proper handwashing behavior should be begun to be accustomed since in elementary school, but students' awareness is relatively low. This is alleged because they assumed that their hands look clean. In this community engagement activity on how to wash hands properly, hundred students in national primary school SD Negeri 57 Banda Aceh, Indonesia were involved from March until June 2019 and then ten students were chosen as ambassador of handwashing (ducuta). Two selective media agars were used to grow microbes from the hands of the students before and after hand washing. Several programs (secuta, mocuta, bacuta, and kacuta) were also conducted to measure the success of this activity. There was an increase in understanding the proper way of handwashing from 78% before socialization to 96% after the socialization. The results based on the handwashing activity book (bacuta) showed that 50% of the ducuta have begun to get used to washing their hands properly before eating, after going to the toilet, and after playing recommended by WHO.

Various designs of stent are available commercially in the marketplace. Thus, it was difficult to select the suitable stent that meets to the varying needs of the patient beyond the material, such as flexibility, inflated diameter, and radial strength. The present study would focus on finding the effect of link design to its flexibility, while the strut design was remained and the material was the same. The study was carried out by finite element modeling and software ABAQUS 6.13 was employed to perform the simulation. The metal alloy of Cobalt has been selected to be material of the stent model. A thin stent model consists of a pair of the strut which was connected by three links (L1, L2, L3) with a thickness of 60µm and 80µm frame wide. The model has a size of 1.237mm in outer diameter and 2mm long. The flexibility was expressed by the curvature index as the ratio of bending angle to stent length. The flexibility was performed at the bending moment concerning x-axis (Mxx) and y-axis (Myy). Results indicated that link design L1 performed the highest flexibility compared to other link designs which was indicated by the highest curvature index at the same value of bending moment (Mxx and Myy).
