ABSTRAK
Telah dilakukan penelitian tentang analisis variabilitas temperatur udara selama periode 2003-2012 di daerah Kototabang. Temperatur udara diukur dengan optical rain gauge (ORG) dengan sampling data temperatur setiap satu menit. Dari hasil perhitungan diperoleh nilai batas atas tertinggi yaitu 32,2 °C dan nilai batas bawah terendah yaitu 19,0 °C. Pola rata-rata temperatur di Kototabang mulai mengalami kenaikan pada pukul 07:00–08:00 WIB dan mengalami puncaknya pada pukul 12:00–13:00 WIB. Dari pukul 13:00-14:00 temperatur mengalami penurunan hingga pada pukul 19:00–20:00 WIB dan temperatur mulai stabil hingga pukul 23:00-24:00 WIB. Nilai rata-rata temperatur harian tertinggi di Kototabang terjadi pada tanggal 11 Juni 2010 yaitu sebesar 25,4 °C dan nilai rata-rata temperatur terendah terjadi pada tanggal 3 September 2007 yaitu sebesar 18,8 °C. Temperatur bulanan tertinggi terjadi pada bulan Mei yaitu 23 °C dan terendah terjadi pada bulan Desember yaitu 22 °C. Rata-rata temperatur bulanan tertinggi terjadi pada saat curah hujan bulanan terendah dan begitu pula sebaliknya. Temperatur tahunan tertinggi terjadi pada tahun 2003 yaitu 22,4 °C dan yang terendah terjadi pada tahun 2008 yaitu 21,9 °C. Secara umum kenaikan dan penurunan temperatur masih berada dalam range batas atas dan batas bawah kecuali untuk rata-rata temperatur harian terendah. Faktor lokal masih mendominasi pola temperatur di Kototabang dan tidak adanya kecendrungan kenaikan temperatur di Kototabang akibat faktor global.

Abstract
The research about variability analysis of air temperature for 2003-2012 in Kototabang area has been conducted. Air temperature were measured using optical rain gauge (ORG) with temperature data sampling was every minute. Results show that the value of upper limit was 32.2 °C and the value of lower limit was 19.0 °C. The average daily temperature in Kototabang start to increased at 07:00-08:00 and the reached the highest value at 12:00-13:00. The temperature decreased from 13:00-14:00 until 19:00-20:00 and start to stabile at 23:00-24:00. The highest of average daily temperature occurred at June 11, 2010 that was 25.4 °C. The lowest average daily temperature occurred at September 3, 2007. Its value was 18.8 °C. The highest monthly temperature was 23 °C in May and the lowest temperature was 22 °C in December. The highest monthly temperature occurred when the rainfall was the lowest and the lowest temperature occurred when the rainfall was the highest. The highest annual temperature was 22.4 °C in 2003 and the lower annual temperature was 21.9 °C in 2008. In general, the increasing and decreasing of temperature was still in upper and lower limit, axcept for the lower average daily temperature. Local factor was still predominate the temperature pattern in Kototabang and there was no increasing temperature trend that caused by global factor in Kototabang.
