Water availability to plants is scarce in the dry season due to intensive solar radiation, high temperatures, increased wind speed, and also due to reduced humidity. The minimal availability of water for plants causes the plants to wilt and the productivity of coffee plants decreases. However, from observations in South Malang, water can still be accessed by coffee plants in several locations. This research aims to determine the fundamental factors that cause water to remain available at the peak of the dry season using a stratified random sampling research method with 9 observations points in a 30m x 30m plot, repeated four times, and observed three times. The parameters examined include the microclimate of coffee plants (air temperature, air humidity, intensity of solar radiation, and wind speed), soil physical properties (soil bulk density, soil weight density, soil porosity, soil texture, and soil water content at various levels), altitude, and number of coffee plants and their shade. The analysis used in the research uses correlation displayed with a scatter plot of two simple variables. © Published under licence by IOP Publishing Ltd.
