STUDIES OF THERMAL COMFORT IN THE JAKARTA NORTH COAST TOURISM REGION OF INDONESIA.

This study explored the use of thermal indices to determine the comfort of coastal tourism areas in the tropics. The study area was chosen at the Ancol Eco-Park (EPA) because this place is a nature-based tourist attraction. Located in the north of Jakarta with an altitude of 3 m above sea level (masl). The thermal indices used are Physiologically Equivalent Temperature (PET) and Universal Thermal Climate Index (UTCI). Determination of thermal sensations using the 7-region reference namely; PET in Europe, PET in Taiwan, PET in Tianjin, PET in Tel Aviv, UTCI in the Mediterranean, UTCI in Tianjin and UTCI. The category of thermal sensations from the calculation results is compared with the results of the visitor survey. Visitors who became respondents in this study were 219 people. Based on the thermal sensation criteria from 7 EPA reference areas throughout the year, they are not in the comfort zone except PET in Taiwan, namely in January, February and July. Insitu measurement results obtained PET average daily = 34.5?C and UTCI daily average = 35.5?C. The score based on the range of thermal sensations in PET in Taiwan is in the warm (uncomfortable) category. Whereas based on visitors\\\' answers, the score is comfortable. Environmental conditions also provide a comforting effect on visitors because the majority of visitors are interviewed in the shade such as around trees and rest areas.
