A part of peatlands in Indonesia developed above sulfidic material. They spread around the tidal swamps area. Vertical tide movement will certainly bring a consequences to the behaviour of both materials, such as ash content and electrical conductivity properties. The research was conducted to study ash content and electrical conductivity of peatland with several thickness and acid sulphate soil under some hydrological conditions. The results showed that ash content and electrical conductivity decreased with increasing of peat thickness, especially in upper layer of peatland. Decrease and disappear of peat layer has increased the ash content and electrical conductivity in the peat layer and in the sulfidic layer. Declining of ground water level increased electrical conductivity of soil.
