This study observed the changes in chemical properties of peat soil and ground water after irrigation of two peat types: inland and transition peat. The research was carried out in the Basic and Analytic Laboratory of Palangka Raya University. Inland peat and water samples were obtained from Palangka Raya City, meanwhile and transitional peatland was taken from Pulang Pisau Regency, Central Kalimantan Province. Research methods consisted of survey and experimental test with complete randomized design (CRD) consisted of groundwater irrigation treatment and was repeated 3 times. The experimental parameters are soil chemical properties such as Ash Content, Base Saturation (KB), Nitrogen (N), Phosphor (P), Exchangeable Potassium (K-dd), Interchangeable Sodium (Na-dd), Interchangeable Calcium (Ca-dd), Interchangeable Magnesium (Mg-dd), Cation Exchange Capacity (CEC), Aluminum Saturation, Iron (Fe), Sulfate (SO₄), Hydrogen Concentration (pH), and Electrical Delivery Power (EDP), and water chemical properties such as pH, EDP, cation, and anions.. The results showed that there has been an increase in the value of CEC, P, Na-dd, SO₄, pH, and decreased of Ash Content, N, K-dd, Ca-dd, and EDP on transitional peat soils. Meanwhile, the inland peat soils showed an increase of Ash Content, N, P, Mg-dd, a saturation of Al and Fe, and decreased in the value of CEC, Ka-dd, Na-dd, Ca-dd, SO₄, pH, and EDP. There were similar effect of groundwater irrigation, towards soil chemical properties, with an exeption of iron levels (Fe). Iron levels (Fe) in transitional peat increase, but decreased in inland peat.

The utilization of peat soil as a planting medium is still faced with several problems, especially in terms of the chemical characteristics of peat soil. Therefore, there is a need for treatment to improve these problems, one of which is by using the poration of palm oil empty fruit bunches and dolomite. This research aims to determine the effect of providing a technology package of empty fruit bunch and dolomite poration doses on the growth and yield of red spinach plants. The research was carried out at the Greenhouse Jalan G. Obos 24, for 3 months (September-November 2023). The research was carried out using a survey method and experimental tests in polybags, using the RAL method with 9 treatment technology packages, namely: 1) soil without treatment (control), 2) Soil + empty fruit bunches poration 2.5 tons ha-1 + dolomite 2 tons ha-1, 3) Soil + 2.5 tons ha-1 of empty fruit bunches poration + 4 tons of ha-1 dolomite, 4) Soil + 5 tons of ha-1 of empty fruit bunches poration, 5) Soil + 5 tons ha-1 of empty fruit bunches poration + 2 tons ha-1 dolomite, 6) Soil + empty fruit bunches poration 5 tons ha-1 + dolomite 4 tons ha-1, 7) Soil + empty fruit bunches poration 7.5 tons ha-1, 8) Soil + empty fruit bunches poration 7.5 tons ha-1 + dolomite 2 tons ha-1 , 9) Soil + empty fruit bunches poration 7.5 tons ha-1 + dolomite 4 tons ha-1. The variables observed included plant height, stem diameter, root length, plant wet weight, and plant dry weight. Providing a package of peat soil + 7.5 tons ha-1 of empty fruit bunches poration + 4 tons of ha-1 dolomite (T(8)) can increase the growth of red spinach plants which include plant height (4.46 – 37.36 cm), stem diameter (4.48 – 7.06 cm), the wet weight of the plant is 26.10 g/polybag. Keywords : poration, dolomite, plant height, palm oil empty fruit bunch

Road infrastructure development often faces significant challenges due to low bearing capacity of the subgrade, especially when dealing with peat soil. This condition can lead to excessive settlement, deformation, and premature damage to the road pavement, resulting in high maintenance costs. Peat soil is inherently poor in quality, making it uneconomical to use as a subgrade for road pavements. The condition of peat soil significantly impacts road construction in Central Kalimantan Province. Therefore, one effective way to address this issue is through soil stabilization. This research aims to explore the potential of biochar and cement as stabilizing agents to improve the bearing capacity of peat soil. The study involves a series of laboratory tests, including initial physical property tests of the original peat soil, as well as index and mechanical strength tests after the addition of a combination of biochar and cement. The biochar used in this research is derived from coconut shells.The conducted tests include compaction tests to determine the maximum dry density and optimum moisture content, and CBR (California Bearing Ratio) tests to evaluate the soil's bearing capacity. The variations in biochar and cement addition were: 5% biochar with 5% cement, 5% biochar with 6% cement, 5% biochar with 7% cement, and 5% biochar with 8% cement. The research results indicate that the addition of biochar to peat soil stabilization mixtures using cement significantly increases the CBR value. Specifically, adding 8% cement and 5% biochar to peat soil was able to increase the CBR value by up to 9% from the original soil's CBR of 2.2%. Therefore, it can be concluded that the combination of biochar and cement can transform peat soil into a usable subgrade for road construction
