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.

Central Kalimantan covers an area of 157,983 km2 with more than 2,000 km2 of tropical peatlands, which is one of the buffer regions of Indonesia's new capital government city. However, the sad story is the conversion of about one million hectares from peat swamp forests (PSF) to rice fields occurred in the mid-1990s, so called the Mega Rice Project (MRP). Since then, forest and peatland fires become an annual event due to high level of degradation under the climate change symptoms such the frequent of the El Niño event. In very strong El Niño of 2015, Indonesia has returned to the world spotlight in relation to the fires and the haze crisis. The most fire prone area was recorded in the iconic Tumbang Nusa, Pulang Pisau Regency and its adjecent areas. However, the thick haze had covered almost the entire province. There are the dis-adventages impact during more than two months. Therefore, this study was to investigate what are the causes and the impacts of this disaster at the site level. This research location was focuses on three regencies and one city namely Pulang Pisau, Kapuas, Katingan and Palangka City. The method was a Focus Group Discussion (FGD) with key figures representing eight clusters of village communities. This method is also supported by statistical, hotspots and spatial data for additional analysis. The result are only two villages with very high average of hotspot and eight with high average of hotspots in Pulang Pisau and Kapuas Regency. Further, the FGDs in seven villages showed that there were three main clusters that caused forest-land fires, namely natural factors, human factors and village policy / regulation factors. The villages study that were affected by the fire in 2015 showed there were three main impacts namely on people, environment and capital. This result is a foundation of cause-effect factor for further Root Cause Analysis to find out the options for fire prevention and management in climate change mitigation efforts.

The irreversible drying indicated by the hydrophobic characteristic is one of the characteristics of peat which can be used to indicate the level of peatland degradation. Hydrophobic peat usually occurs as a result of fire or intensive drought which is mainly caused by peat land conversion. The objective of this research is to study the effect of land use on peat hydrophobicity, based on FTIR spectra and water penetration drop time. The result show that hydrophobicity characteristics of peat is influence by land use differences. The abandoned or scrub land has higher hydrophobic characteristic which indicated by slow water penetration time and the higher hydrophobic index based on the FTIR method, compared with rubber and palm oil plantation. Organic compounds that appear and cause peat to become hydrophobic include carboxyl, hydroxyl phenolic groups, and high lignin content.

Peatland is a specific ecosystem that is always waterlogged and has multiple functions, including economic, hydrological, environmental, cultural, and biodiversity functions. Existing peatlands, especially in Central Kalimantan, have great biodiversity potential. This potential provides benefits for people living in peat areas. This diversity of biodiversity has the potential of medicinal plants that have not been maximally explored. Therefore, through this activity, data will be obtained regarding the types and potential of medicinal plants in inland peat areas, which will facilitate their management. This research activity was carried out in the “Handak Maju” IUPHKm area for 3 (three) months, from July – September 2022. The implementation method is carried out through survey activities and field observations and carrying out of the Focus Group Discussions, as well as related literature studies. Based on the results of the survey conducted, it was found that several types of medicinal plants have the potential to be developed and preserved. According to Zuhud (1991) that medicinal plants are plants whose plant parts (leaves, stems or roots) have medicinal properties and are used as raw materials in the manufacture of modern and traditional medicines. It was further revealed that, medicinal plants are still not widely cultivated. However, the advantages of treatment using traditional medicinal plant ingredients are generally considered safer than the use of modern medicine. This is because traditional medicine has relatively fewer side effects than modern medicine.
