Abstract

PT. Mitrasukses Engineering Indonesia (MEI) is a manufacturing company specializing in custom machine production. The company has an operational division responsible for managing product orders until they are delivered. The main problem in the operational division of PT. MEI is the inconsistency between product designs and customer needs, leading to machine design redesigns and delays in order processing. Therefore, a more detailed analysis of potential errors is required, followed by recommendations for improvement through business process improvement. The methodology used to analyze potential errors is the Failure Mode and Effect Analysis (FMEA) method. Meanwhile, the methodology used to provide improvement recommendations is the Business Process Improvement (BPI) method with the streamlining tools. The improvement measures adopted include streamlining tools such as Standardization, Upgrading, Simplification, Automation, and Error Proofing. Simulations will be conducted after modeling the improved business process based on the improvement recommendations. The simulations compare the time between the current business process model (as-is) and the improved business process model (to-be) to determine the percentage increase in efficiency. Efficiency occurs due to changes in process activities in the current business process that has been improved. The simulation results indicate an efficiency improvement in the product ordering process by 16.58%, material procurement process by 35.37%, production process by 38.85%, and product delivery process by 22.42%.

Abstract

Livin' by Mandiri is a mobile banking application that is integrated with Bank Mandiri banking services and its digital ecosystem. However, some users reported negative responses regarding usability aspects. This study aimed to determine the usability problems faced by users, measure the level of usability, and recommend the user interface design for usability improvement. The evaluation was carried out using the Usability Testing method which collected quantitative and qualitative data. Quantitative data was collected by measuring usability metrics data gathered while participants worked on task scenarios and filled out questionnaire. Meanwhile, qualitative data is collected through interviews with participants to gain insight from users on usability issues. The evaluation of the existed application show that the value of the learnability aspect was 68%, the efficiency was 0.013189 goals/sec, the error was 33.28% and the satisfaction aspect score was 73.5 (good). Participants said that the difficulties they faced most were features or menus that were difficult to find or unknown. Next, recommendations were construct to solve the problem by implementing usability guidelines. The user interface design recommendations were manifested in a high-fidelity prototype. The prototype was also evaluated with the usability testing method. The prototype evaluation showed an improvement of usability. The learnability aspect increased to 93%, the efficiency aspect increased to 0.026295 goals/sec, the error decreased to 2.34%, and the satisfaction aspect score was 84.4 (excellent).
