| This study aims to compare particle grain size and moisture content in samples from beach sediment and paddy fields. Grain size variations were measured along different zones and stations in a line transect at each location. The grain sizes for both study areas were determined using drysieving and a Laser Diffraction Particle Size Analyzer. Results showed that beach sediment mostly consists of medium sand, is moderately sorted, very negatively skewed, and extremely leptokurtic. In contrast, paddy field sediment is mostly very fine silt, very poorly sorted, negatively skewed, and very leptokurtic. The mean of particle grain size recorded in beach and paddy field were 1.57 _ 0.23 and 7.63 _ 0.44 respectively. Moisture content was measured using oven-drying method. The mean of moisture content recorded in beach and paddy field were 6.72 _ 5.01% and 52.03 _ 3.35% respectively. Results revealed that paddy fields have significantly higher moisture content than beach sediment. Descriptive analysis from the data normality tests showed that the particle size and moisture content were not normally distributed however, there is significant difference in moisture content and particle size between both study areas that were due to continuous flooding in paddy fields, which retains fine particles and high moisture, while coastal areas experience tidal action that removes fine particles, leaving coarser sediments with lower moisture retention. The findings of this study can contribute to strategies for mitigating beach erosion and optimizing agricultural practices in paddy fields, ensuring sustainable environmental and land-use management.
