Peatland is a land with high C-organic content and it functions as a carbon sink. However, peatland is prone to burning due to the opening and utilization of farmland by burning or slashing-burning. Fires on peatlands can cause damage to the composition and structure of vegetation and damage to the physical and chemical peat soils. The purpose of this research is to analyze the change of physical and chemical of peat soil in post fire field, and to determine the type of cover crop for peatland post-fire recovery. Activities are carried out in natural forests and post-fire land. Intake of soil samples purposively by using ring sampler and direct measurement of peat depth, ground water level and peat maturity. Characteristics of soil physical properties of soil analyzed are bulk density, moisture content, pH, CEC, C-organic, N-total, P-available, Number of Cationic Bases, and Saturation Bases. Sampling of soil chemical properties was done composite on each path with a total weight of 1kg. The type of plants to be selected for recovery is a type of cover crop that refers to Law No.37 of 2014. The results show that the weight of the bulk density in Natural Forest is 0.2058g / cm3 and in Post-Fire Land 0.226 g / cm3; water content in Natural Forest 311,33% and in Post-Fire Land 309,98%. Soil pH in Natural Forest 2.8 and in Post-Fire Land 3.4; P-available Natural Forest land is 180.2 ppm and in Post-Fire Land 438.5 ppm, Total Soil Cationic bases in Natural Forest is 13.855 me / 100g and in Post-Fire Land is 25.02 me / 100g; Saturatin bases in Natural Forest is 9.5% and in Post-Fire Land is 18%. The level of C-organic soil in Natural Forest is 50,005% and on Land of Post Fire is 49,88%, CEC in Natural Forest is 148,065 me / 100g and on Post-Fire Land is 137,35me / 100g, and N-total land at Natural Forest 2.035% and on Post Fire Land is 1.44%. The t-test test at 95% confidence interval indicated that the fire had no significant effect on soil physical properties, but had significant effect on soil chemical properties. The results of the literature study indicate that the type of cover crops for post-fire peat land rehabilitation is a type of Legume Cover Crop that is able to survive in the condition of the flooded soil and poor nutrients. Types of ground cover plants that can be used in the study sites are Callopogonium muconoides, Centrosema pubescens, Mucuna sp., Crotalaria juncea, Arachis pintoi, and Pueraria javanica.
