Sistem Perbaikan Ekofisiologi Tanaman Segon (Paraserianthes falcataria (L) Nielsen ) Di Kecamatan Wagir Malang

Sengon plant (Paraserianthes falcataria (L) Nielsen) in Indonesia is one of the
types of plants developed in the development of Community Forestry especially in Wagir
District, Malang Regency. This study was conducted to analyze the effect of environmental
conditions, especially temperature and humidity on stomata density and chlorophyll levels in the
plant Sengon (Paraserianthes falcataria (L) Nielsen) and analyze the soil nutrient content under
the Sengon stand (Paraserianthes falcataria (L) Nielsen) on plant physiology in Sukodadi
Village, Wagir District, Malang Regency. The techniques used are field surveys, leaf sampling
to measure physiological properties (stomata density and chlorophyll content), and soil
sampling to measure soil chemical properties (macro nutrient content), as well as direct
observations in the field to measure environmental factors (temperature and humidity). Analysis
of the data used is multiple linear regression in SPSS to determine whether there is influence of
temperature and humidity on the physiology of stomata and chlorophyll as well as descriptive
analysis on soil factors. Research result is that temperature and humadity have an effect on
chlorophyll. This support to possibility of temperature and humadity system in the region so taht
agreed crops will affect the concentration of chlorine.
