[email protected] Abstract. A liveable city is a city with a comfortable environment that gives its residents a sense of perfection to live and ease to do various activities. Balikpapan is one of major cities whose has the third-largest population in the province of East Kalimantan consisting of 6 districts namely, South Balikpapan, East Balikpapan, North Balikpapan, West Balikpapan, Central Balikpapan, and Balikpapan City. The consequence that arises from the large population is the increase in crime that affects the liveability in terms of security quality. In this study, Mamdani Fuzzy Logic is used to investigate the level of security quality of each sub- district in this city based on the crime figures. Moreover, the types of criminalities are categorized into four kinds, namely fraud, theft, immoral violence, and other crimes. Based on the result, it was found that the order of sub-districts with the best level of security is Central Balikpapan which is followed by Northern and Eastern Balikpapan with fairly good security status.
