Conversion of forest function can reduce its area, increase the number of patches, isolation, and cause edge effects. Edge effect is the difference in environmental conditions between interior habitats and forest edges. The presence of edge effects can be indicated by a gradual change in abiotic and biotic factors from the edge to the forest interior. This study aims to determine the presence of edge effects based on the analysis of abiotic factors such as physical and chemical properties of soil and microclimate in the edge of the Patengan I Nature Reserve which is adjacent to the road, production forest and microclimate, compared to the interior zone. The physical properties of soil measured were temperature, humidity, bulk density, moisture content, and soil porosity, while the measurement of soil chemical properties includes C-organic, N, pH, and Cation Exchange Capacity (CEC). The microclimate data measured were light intensity, humidity, and air temperature. Soil samples and microclimate data were taken by purposive sampling with three repetitions, then the Analysis of Variance (ANOVA) and Multivariate Analysis of Variance (MANOVA) statistical tests were carried out using SPSS 25 software. The results showed that there was no significant difference (? = 0.05; p> 0.05) on the physical and chemical properties of the soil between the three edge areas compared to the area in the interior zone. Meanwhile, in the microclimate variable, there was a significant difference (? = 0.05; p <0.05) between the edge of the nature reserve adjacent to the tea garden compared to the area in the interior zone which indicated an edge effect.
