Abstract

Marginal lands such as tidal lands used for agriculture face several problems, including shallow pyrite layers, land affected by seawater intrusion (salinity), high soil acidity (low pH) and nutrient-poor soil. The shallow pyrite layers and salinity in Pemusiran Village are major obstacles to agricultural development and have resulted in decreased land productivity. This research aims to determine and analyze the distribution of pyrite layer depth, Soil Electrical Conductivity (EC) and groundwater in Pemusiran Village. This research uses a survey method, where observation points are determined using the grid method. The results of the study showed that the sulfidic material layer (pyrite) of the soil at the research location was dominated by pyrite depth of 50-100 cm, which was included in the potential acid sulfate soil typology (PASS) category, namely PASS-2 with an area of 1,055.32 ha or 45.73% of the total research area. The depth of the pyrite layer at the research location was influenced by the distance from the sea and rivers, land management and the thickness of the peat layer. The soil EC value at the research location ranged from 64-981 μs cm-1 in the very low category. The highest EC value for groundwater was 8,863 μs cm-1 in the poor category and the lowest value was 355 μs cm-1 in the good category. Generally, the highest EC values for soil and groundwater were in coastal areas and were lower in areas far from the coast and rivers.

Abstract

Tropical peatlands are among the largest terrestrial carbon reservoirs; however, their existence is increasingly threatened by hydrological alteration and intensive land-use practices. Pandan Makmur Village, Geragai District, East Tanjung Jabung Regency, is located within a transitional peat–mineral landscape dominated by oil palm plantations and functions as a buffer zone for the Sungai Buluh Peatland Protected Forest. This condition renders the area both strategically important and highly vulnerable to peatland degradation and subsurface carbon loss. This study aims to analyze the magnitude and spatial distribution of subsurface carbon stocks in peatlands using a Geographic Information System (GIS)-based approach. The study employed a semi-detailed soil survey method with a systematic grid design of 700 × 700 m. Field data included peat thickness, peat maturity level, bulk density, water content, and organic carbon (C-organic) content, analyzed at two soil depths: 0–30 cm and 30–60 cm. All parameters were integrated into a raster-based GIS with a spatial resolution of 20 × 20 m to calculate and map subsurface carbon stocks spatially. The results show that peat and peaty soils in Pandan Makmur Village cover approximately 1,048.7 ha and are predominantly composed of thin to shallow peat with a sapric maturity level. The total subsurface carbon stock is estimated at 370,566 tons, with the largest contribution originating from the 0–30 cm layer (93.2%), while layers deeper than 30 cm contribute only 6.8%. At the same thickness, the surface peat layer stores nearly twice as much carbon as the underlying layer. These findings confirm that the upper peat layer is the primary carbon storage compartment and simultaneously the most vulnerable to carbon loss. Therefore, protection of the surface peat layer and sustainable water management are essential for carbon emission mitigation and sustainable management of transitional peatland ecosystemsKeywords : Activation, Adsorption, Crude Glycerol, Natural Zeolite from Malang
