Analisis Tingkat Kenyamanan Di DKI Jakarta Berdasarkan Indeks THI (Temperature Humidity Index)

Abstract

ABSTRAKFenomena iklim mempengaruhi kenyamanan fisiologis di daerah pemukiman. Analisa tingkat kenyamanan di DKI Jakarta dilakukan menggunakan THI (Temperature Humidity Index). Berdasarkan data iklim periode 1985 – 2012 stasiun Kemayoran, Tanjung Priok, Halim, Cengkareng dan Pondok Betung, hasil penelitian menunjukkan rata-rata prosentase tingkat kenyamanan harian dengan kategori tidak nyaman sebesar 22,1 % (81 hari per tahun), sebagian nyaman 71 % (259 hari per tahun) dan nyaman 7,1% (26 hari per tahun). Tingkat kenyamanan menunjukkan semakin ke tengah kota semakin besar prosentase tidak nyaman. Selama periode tersebut terjadi kecenderungan peningkatan indeks THI dengan signifikansi > 50% menunjukkan tingkat kenyamanan di DKI Jakarta cenderung semakin tidak nyaman.Kata kunci: tingkat kenyamanan, temperature humidity index, urban heat islandABSTRACTClimate phenomenon affects physiological comfortableness in residential area. Analysis of thermal comfort level in DKI Jakarta were conducted using THI (Temperature Humidity Index).  Based on climate data stations in Kemayoran, Tanjung Priok, Halim, Cengkareng dan Pondok Betung during 1985-2012 showed that the average percentage of daily thermal comfort level with categories uncomfortable were 22,1% (81 days per year), half comfortable 71 % (259 days per year) and comfortable 7,1% (26 days per year). The study showed that the greater percentage uncomfortable level, the closer into the center of the city and during 1985 to 2012 the THI index tend to increasing with significant level more than 50% meant that the thermal comfort level tend to more uncomfortable.Keywords: thermal comfort level, temperature humidity index, urban heat islandCitation: Wati, T dan Fatkhuroyan.
