Abstract
Coastal areas have high agricultural potential but are vulnerable to salinity problems due to seawater intrusion. Buduran District, Sidoarjo Regency, is a coastal area located near Ketingan Beach and is prone to increased soil salinity, which may affect the fertility of paddy fields. This study aimed to analyze the effect of distance from the coast on soil salinity levels and its relationship with soil fertility. The methods used included analysis of soil physical and chemical properties such as texture, bulk density, water holding capacity (WHC), pH H₂O, pH KCl, organic carbon (C-organic), P₂O₅, and cation exchange capacity (CEC), as well as salinity analysis using Exchangeable Sodium Percentage (ESP) and Sodium Adsorption Ratio (SAR). Soil fertility evaluation was conducted using the Fertility Capability Classification (FCC) method. The results showed that the soils were dominated by clay to loam textures with generally favorable physical conditions. Soil pH ranged from neutral to slightly alkaline, P₂O₅ content was high, and CEC values were in the moderate category. Organic carbon content was low to moderate and became the main limiting factor for soil fertility. ESP values (3.10–5.45%) and SAR values (0.21–0.42) indicated that the soils were non-sodic; however, early indications of salinity were observed in areas closer to the coast. Overall, soil fertility status ranged from moderate to high. In conclusion, the distance from the coast influences soil salinity levels in Buduran District; however, the soil conditions remain suitable for agricultural activities. Proper land management practices such as the addition of organic matter, improvement of drainage systems, and appropriate irrigation management are necessary to maintain soil fertility and prevent further salinity development.
