Peatlands are important due to their high carbon storage, their role in suppressing climate change processes, and their importance for local and global communities’ livelihood. Large amounts of organic carbon pools in peatlands can be released into the environment as gaseous emitted carbon and lost through waterways (fluvial). The carbon released through the water stream consists of organic and inorganic forms and is partly in the form of CO2 and CH4 gases. The organic form consists of dissolved organic carbon (DOC) and particulate organic carbon, where DOC is the most dominant organic carbon in water sourced from peatlands. This research's objectives were to study the DOC concentration of peat water resulting from the hydrological condition's difference and the peat thickness overlaying the sulfidic substratum. The study was carried out in the Pangkoh area of Pulang Pisau district of Central Kalimantan. Peat water is taken on PVC pipes installed on each plot representing different peat thicknesses (deep, moderate, and shallow peat) at a depth of 25, 50, 100, 150, 200, and 250 cm from the soil surface. The water sampling was conducted on the peak wet season, during the transition from wet season to dry season and during the peak dry season. The results showed that DOC was influenced by peat thickness, depth of sulfidic material, and groundwater level. The release of DOC is higher from the deep peat than from the thin and moderate peat. The difference in DOC concentration between peat thickness is also related to the electrical conductivity of the peat water. The results showed a negative correlation between electrical conductivity and DOC concentration. The negative correlation was significant in the observation of the rainy and dry seasons, while in the transitional season, it was not significant.

Evaluation of land suitability and soil fertility status is useful for assessing the potential of agricultural areas. This research aims to determine the physical, chemical properties, soil fertility status, factors that influence land suitability classes and land suitability classes (actual and potential), as well as to obtain improvements and directions for land use. This research is a qualitative descriptive study. Analyze data by matching land characteristics with land use. The research results show low soil fertility status. The limiting factors for land suitability classes are temperature (tc), water availability (wa), oxygen availability (oa), rooting media (rc), nutrient retention (nr), available nutrients (na), erosion hazard (eh) and danger flood (fh). The land suitability classes in SPT I-II are actually marginally suitable (S3) and in SPT III-VII are not suitable (N) and potentially in SPT I and II are quite suitable (S2) and very suitable (S1). Improvement efforts are carried out on land limiting factors. Land use directions are recommended in SPT I and SPT II.

Penelitian ini bertujuan menganalisis sifat fisik dan kimia tanah menurut umur reklamasi dan rona awal lingkungan pada lokasi penelitian yaitu lokasi bekas penambangan bauksit dalam wilayah izin usaha pertambangan PT. Citra Mentaya Mandiri dan PT. Duta Borneo Pratama. Hasil analisa laboratorium terhadap sampel tanah pada 5 (lima) lokasi dengan ketebalan 0-20 cm yakni rona awal, lokasi belum reklamasi, reklamasi 1 tahun, reklamasi 2 tahun, dan reklamasi 5 tahun. Analisis data menggunakan uji sidik ragam dan uji lanjutan BNT (Beda Nyata Terkecil). Hasil penelitian ditemukan perbedaan sifat fisik dan kimia tanah menurut umur reklamasi dan rona awal lingkungan, namun tidak berbeda nyata terhadap kapasitas tukar kation pada lokasi tersebut. Kondisi sifat fisik tanah ditemukan pencampuran antara lapisan tanah atas dengan lapisan tanah bagian bawah akibat penambangan dan penimbunan tanah. Tekstur tanah berupa liat berdebu - lempung berpasir. Struktur tanah berupa gumpal bersudut - gumpal membulat dengan ukuran pasir berdebu dan tingkat perkembangan sukar hancur - mudah hancur. Penurunan bobot isi tanah akibat presentase fraksi, penambahan bahan organik, vegetasi, dan aktivitas fauna yang berbeda. Kondisi sifat kimia tanah yaitu pH tanah tergolong asam berkisar antara 3,71 – 4,91. Penurunan kandungan N-total, P-total, C-organik mengalami penurunan disebabkan karena pH tanah yang asam, kurangnya vegetasi dan bahan organik. Perbedaan nilai Kalium dan Kejenuhan Basa disebabkan jumlah kandungan unsur hara dipengaruhi oleh serapan unsur hara, pencucian, jenis pupuk dan jumlah pupuk yang diberikan. Kapasitas tukar kation bervariasi nilainya tetapi tidak berbeda nyata, diduga karena kekurangan bahan organik pada lokasi reklamasi. Rekomendasi dalam pengelolaan tanah antara lain penambahan bahan organik, vegetasi dan unsur hara agar terjadi proses humifikasi dan dekomposisi tanah dapat meningkat.

Measuring air retention in constructed canal blockage is critical for determining changes in air content after canal blocking. The purpose of this study is to assess the influence of changes in levels on air retention values measured at three depths, namely 0-20 cm, 20-40 cm, and 40-60 cm, at four transect sampling stations created at a distance of 10 m to 260 m from the canal block. Changes in bulk density, porosity, and peat volume affect groundwater. Peat soil samples were collected from burned peatlands, and canal blocks were constructed. A pressure plate chamber was used to assess air retention. The findings of the investigation revealed that the air retention pattern of peat soil at 16 test sample locations was at maximum at PF 0.2 at each depth. At higher pressures (pF 2-4.2), peat groundwater is strongly bonded by peat soil particles. The average bulk density of peat is 0.2 2 and the porosity value is 86.79%. The higher the air content at each pF value has no influence on the porosity and bulk density values. Changes in air content between pF 2.0 and 4.2 lower average peat volume by 7.4%. The size of this value is assumed to be determined by the peat's type, maturity, and decomposition value.
