Therefore, learning Mandarin is something that is quite important in this era of globalization. However, to learn Mandarin is not an easy thing because Mandarin is a language that is quite difficult to master. So that it can reduce motivation to continue learning and in the end decide to stop learning Mandarin. Based on these problems, in this study, we will design and develop a mandarin learning application with the gamification method using the Octalysis framework to increase motivation in learning Mandarin. and will measure the level of behavioral intention to use and user immersion towards the application using the Hedonic Motivation System Adoption Model (HMSAM). The tests have been conducted and prove that gamification can increase the user's motivation to continue learning Mandarin. This is shown based on the evaluation conducted, the user states strongly agrees that the application that has been designed and built can improve the behavioral aspect of intention to use, this is indicated by the percentage value obtained by 82.47%. And agree that the application can cause immersion aspects when using the application, this is indicated by the percentage value obtained by 79.56%.
