Identifikasi Kenyamanan Kota Tanjungpinang Berdasarkan Indeks Panas Humidex

Abstract

The development of Tanjungpinang City in several sectors is an effort to make that city more advance. However, there is an important problem that needs to be considered. It is the problem of the comfort life index for the population who are living in Tanjungpinang City. The climate change can affect physiological comfort in an area. The increasing of temperature can trigger the Urban Heat Island. The aim of this study is to know the comfort life index in Tanjungpinang City using a heat index called as Humidex. The data are the air temperature, air humidity, and surface wind speed for the period of 1989-2018 from the Tanjungpinang Meteorological Station. The comparison of Humidex to wind speed and the number of vehicles in Tanjungpinang City was calculated to determine the effect on the heat index in Tanjungpinang City. The results show that the Humidex monthly average in the Tanjungpinang City area ranged from 32.6 to 34.0 °C. The highest Humidex monthly average is in May and June, and the lowest value is in January. The tendency of increasing Humidex ranged from 0.08 to 0.9 °C and decreasing ranged from 0.07 to 0.8 oC with the determinant coefficient value is 0.55. The increasing of wind speed impacts to decrease the value of Humidex. The increasing of the number of vehicles periodically impacts to increase the value of Humidex exponentially. There is an increasing of the thermal comfort when there is a decreasing value of Humidex or vice versa.

Profil Tingkat Kenyamanan Udara dan Hubungannya Dengan Hari Hujan di Bukit Kototabang Tahun 2010-2018

“…Dalam kenyamanan termis, manusia merasakan sensasi panas atau dingin sebagai wujud respon dari sensor perasa yang terdapat pada permukaan kulit terhadap perubahan suhu udara [3]. Ilmu kenyamanan termis hanya membatasi pada kondisi udara tidak ekstrem (moderate thermal environment) dimana manusia masih dapat mengantisipasi dirinya terhadap perubahan suhu udara di sekitarnya [4].…”

“…Tren peningkatan nilai indeks panas di wilayah Kota Tanjung Pinang disebabkan akibat semakin meningkatnya perubahan penggunaan lahan menjadi lahan terbangun, galaknya program urbanisasi, dan maraknya penggunaan kendaraan bermotor. [4] Selanjutnya ada penelitian Indeks Panas Humidex di DKI Jakarta Hasil menunjukkan rata-rata Humidex bulanan di wilayah DKI Jakarta berkisar antara 36,1 s.d. 39,5 °C dan hubungan antara kecepatan angin dengan Humidex adalah menurunkan nilai Humidex yang berdampak pada peningkatan rasa nyaman termis.…”
