Based on Table 1, there have 4 places with different data of microclimate and canopy area measurement. As we can see, relative humidity (RH) at Place 4 is higher than others with 67.1 RH and Place 1 is 60.1 RH as lowest data than others. For temperature, Place 1 has the highest temperature with 32.2 °C and the lowest temperature is at Place 3 and 4 with 31.7 °C. For the wind speed, Place 1 has the highest value with 7.4 km/h and the slowest wind speed value is at Place 4 with 2.4 km/h. Then, for light intensity, Place 1 has the highest value with 470.0 LUX and the lowest value at Place 4 with 59.0 LUX. Lastly, for canopy area, the largest is at Place 4 with value 62.26% and the lowest value is at Place 1 with 0% of canopy area.
All the microclimate measurement is related to the canopy area. It is because the influence of forest on their environment forms part of a huge and complex relationship between environment and forest vegetation. Environment generally refers to the sum total of various components of universe that affect life on this earth such as soil, water, and climate (Abdul Sahim Ansari, 2003).
Based on Table 1, Place 4 is a closed area because the canopy area at range 50 – 70 % which is 62.26 %. So, all the microclimate measurement data were effects such as relative humidity (RH) is highest than the others with 67.1 RH and the temperature is lowest than the others with 31.7 °C. So, relative humidity also can give the forest in cooler temperature because air in the forest is cooler and moisture. It is also caused by closed gap in these plots. The wind speed also the highest because this area is open area with road beside the area but there have all the big tree around this, so this can influence the wind speed of this area. Then, the light intensity is lowest than others with average 59.0 LUX and this is because of the canopy area is closed and light intensity cannot enter the surface of area floor.
