    Workstation arrangement is one of the factors that can give a significant impact on the company’s performance. Poor implementation of the workstation can lead to an ineffective and inefficient work system which may limit the rate of productivity, poor utilization of resources, high rate of rejection, and many more. For the company of this study, which is XYZ Furniture Sdn Bhd, they face limited production over a certain period by using existing machines which can make the production rate become inefficient. Thus, this study is conducted to solve the problem by proposing several solutions to the company. Based on the findings obtained from this method, the researchers found that there are some shortcomings in the workstation layout that has been used in the factory that causes them to be unable to maximize daily production and cause them losses due to having to work overtime to ensure their daily targets are achieved. The use of this ARENA simulation method is important because this application can create an overview of the movement of a process with more organized and accurate simulation results. Thus, this study is conducted to solve the problem by proposing several solutions to the company. Based on the result, there was a positive increase of 34 units of wood pieces equivalent to 7.08%. This improvement is very good and gives a considerable impact on the company and can help the company in growing its business in the future.

    The purpose of this research is to simulate the process flow of public healthcare and evaluate the improvement of process flow using ARENA simulation. Lean is a method for process improvement and it can be applied to any process including healthcare sector. The previous study has integrated lean methodology for improving the patient flow by identifying root causes of patient flow problems and proposing a lean patient flow process. Therefore, this study attempts to measure the operation process flow in public healthcare and create an improvement operation process flow simulation model in order to improve the service quality. This study employed qualitative research method and the data collection method was used to observe and face to face interview method. Data were analyzed using the ARENA simulation. The comparison of output from the simulation improvement model and the output from the current model been analyzed to get the differences. According to the result, it can be seen the performance has improved by improving the process flow, reduce the distance, reduce the time and increase the number of patients. All the objectives of this research been achieved. In addition, the takt time and the cycle time of improvement layout has reduced by 12.04% compared with current layout. From the results of the simulation, the improvement layout proved to get the best performance compared to the current layout. Using the improvement layout will help the case study to improve their operational efficiency and will help the process flow of patent become smooth in order to improve the process flow of healthcare in Malaysia toward improving the service quality using lean technique.

    Recently, the acceleration and popularization of beverages in the catering trade are rising. Since the increase in the number of beverages, the use of single-used products is increasing. Gradually, plastic waste or plastic pollution had become a sparked issue and discussion around the world. 3D printing technology and simulation had discussed and utilized in this research. 3D printing technology and simulation often provide beneficial in innovative and improving the existing product. 3D printing technology usually applied in the design, manufacture, and engineering industries. This research aims to create and simulate an innovative beverage cup that can improve the green-environment by using SOLIDWORKS software. Before started design, data collection and idea forming had progress. Observation had used to observe and monitor the existing product. In this research, SOLIDWORKS used as the main CAD software to structure and sketch the 3D model or virtual prototype as well as simulate the 3D model that had designed. For the simulation part, finite element analysis (FEA) was applied, which is drop test analysis to evaluate and estimate the stress, displacement, and strain analysis of the virtual prototype. To evaluate the prototype’s durability, the drop test analysis tested by dropping from 4 meter height and 9.81 m/s2 in gravity. In the end, an actual prototype had fabricated. The result shows the output of this research assist to improve the design towards green environment. The finding of this research concerns the comparison between the existing products and the new actual prototype within the design, function, and green-environment.
