Abstract

This study aims to study the temperature of the earth in the city of Kuala Lumpur. The aim is to identify the temperature distribution pattern and study outside the distribution of earth temperature in the night and day in Kuala Lumpur. This study conducted a primary data through field study. This study uses quantitative methods. The field temperature method collects 12 observation stations using six main zones for eight days during the second monsoon season, from August 11, 2019, to August 18 2019. Data hours are collected twice a day in the night (1 am -4 am) and noon (1 pm - 4 pm). AZ RH TEMP model 77535 use as the temperature measurement tool used to obtain the temperature. This tool also measures temperature, humidity and carbon dioxide. This study uses descriptive statistical analysis and regression techniques assisted by geographic information system (GIS) software for analysis used as the inverse distance (IDW) to predict the earth’s temperature pattern. The result showed that the night’s surface temperature value was 29 0C (station 4, day 4). The highest value during the day is 44.8 0C (station 9, first day). In the meantime, the overall temperature of each station is at normal levels around 29 0C to 32 0C. The temperature difference between places and days is not too high around 3.9 0C only. However, the temperature difference between day and night is quite significant around 19.20C. This difference is typical for the tropics. Overall, the earth’s temperature in the evening is higher than the temperature in the night. In conclusion, urbanization activities in Kuala Lumpur are amongst the factors to the occurrence of rising temperatures in the city. The implication is that adequate measures need to be applied so that this phenomenon can be reduced and can ensure the comfort of living without traces of environmental sustainability.
