The sustainability of MSEs can be achieved by enhancing self-reliance, capacity, and empowerment. Efforts to ensure the sustainability of the MSEs fisheries sector are crucial in preserving the continuity of fisheries resources and livelihoods of coastal communities. This study analyzed the sustainability performance of micro-small-scale fish processing enterprises and how it is related to assets and access to different types of capital, including natural, human, social, financial, and technology in Kendari, Southeast Sulawesi. [A1] [A2] The research method was a survey and in-depth interviews with micro-small-scale fish processing businesses. This research used the livelihood sustainability approach method on the pentagon of assets. The descriptive approach systematically presented the access to livelihood assets of fisheries processing business actors. A pentagonal approach was used to describe the relationship between the five livelihood assets by scoring the indicators of each accessibility indicator asset. The scoring is based on a Likert scale. Scoring was carried out using various measurement scales (nominal, ordinal, interval, ratio, and size scales. Linkages between asset and access variables were identified in the form of a spidergram. [A3] [A4] The results showed that fish processing MSEs in Kendari have the highest asset characteristics of social, nature, human, technology, and financial capital. The ability to survive in a small micro-scale fish processing business was very vulnerable to external environmental factors (access to markets, the COVID-19 pandemic, and seasonal changes[A5] [A6] ).[A7] [A8]  The sustainability performance of fish processing MSEs refers to their ability to keep operating and growing long-term while maintaining a balance between Pentagon assets.  [A1]Please provide the short background and the aim of the research  [A2]DONE  [A3]Please provide the short method  [A4]DONE  [A5]In the end of abstract, please provide the conclusion  [A6]DONE  [A7]Please ensure that the length of abstract not more than >250 words  [A8]DONE
