Model for Determining Thermal Comfort in Fisherman's Residential Areas on Coasts with Humid Tropical Climates

Abstract

In humid tropical climates, the air feels hot and uncomfortable, and residents generally don't feel comfortable doing activities during the day inside and outside the house. The aim of this study is to develop the innovation model of determining the thermal comfort areas of fishing settlements on the coast. This was carried out using quantitative descriptive methods, surveys, observations, questionnaires, in-depth direct interviews, hobo data loggers U12-012, solar power meters, and photo cameras. The analysis technique uses expert systems, certainty factors, and geographic information system based spatial analysis. The research results show that the model for determining thermal comfort using an expert system, certainty factors and GIS-based spatial analysis is innovative, realistic, accurate and significant after being validated using thermal measuring instruments. Fisherman residential areas of 1.14 ha (34.34%) have comfortable thermal comfort <27.1℃ and THI <26℃, exactly at 25.19℃, humidity of 96.12%, THI of 24.99℃, with minimum temperature happening in the morning. The area that feels hot and uncomfortable is as large as 2.19 ha (65.66%) with a temperature of 51.93℃, humidity of 31.69%, and THI of 44.84℃ occurring during the day, with maximum temperatures at around 11:00-14:00 am (GMT+08:00) due to high radiation, lack of vegetation and trees.
