<![CDATA[Livability in coastal settlements is a critical issue, particularly vulnerable to environmental degradation, climate change, and land constraints that directly compromise housing quality, necessitating an integrated approach that bridges technical standards and community perspectives. This study aims to determine the priority of physical livability criteria, analyze the suitability level between importance and performance, and formulate development alternatives in the coastal settlement of Karangsari, Tuban, Indonesia. A quantitative descriptive-explanatory approach was employed, integrating the Analytical Hierarchy Process (AHP) and Importance Performance Analysis (IPA). Data were collected through pairwise comparison questionnaires involving five experts and a perception survey of 95 household respondents. AHP results indicate that facilities, ventilation and lighting, and space adequacy rank as the highest-priority physical criteria, while floor condition emerges as the most dominant building component. IPA analysis yields an average suitability rate of 91%, with sanitation, facilities, building materials, and structural safety positioned in the primary priority quadrant. Integration of both methods reveals convergence on facilities and sanitation, alongside divergence on building quality and spatial comfort. These findings affirm the value of AHP–IPA integration as a contextually grounded analytical framework for assessing and prioritizing physical livability in coastal settlements.]]>
