As the world's culture superpower, cultural diplomacy is an important issue to Indonesia which was noted by the frequency of cultural diplomacy done by Indonesian political figures in recent years. This paper analyzes Bacharuddin Jusuf Habibie's speech in 2014 in the United States to foreign scholars observing the process and system of Indonesian democracy. The aim of this paper is to analyze the quality of the speech's cultural diplomacy and identifying the Indonesian cultural diplomacy speech model by Mr. Habibie. This descriptive qualitative method paper examined Mr. Habibie's speech video, which was published in 2016, through the perspective of linguistics. Specifically, this paper analyzed the speech through a critical discourse analysis (CDA) framework and the cultural diplomacy guide that is published by the Indonesian Ministry of Education and Cultural Affairs in 2018. Although the speech was never explicitly intentioned as a speech to promote Indonesian culture, this paper founds that Mr. Habibie has done the action of cultural diplomacy through this specific speech. However, Mr. Habibie's cultural diplomacy is found to be different from the Indonesia's Ministry of Education and Cultural affairs' cultural diplomacy guide which prompted the need to have a reexamination and re-construction of the guide.
