Soil compaction is an important process in reclamation work because it has a direct effect on the carrying
capacity and stability of the structure on it. This study was conducted on one of the specific work zones of Area
C1a in the Patimban Port reclamation project. where sand material from various quarry sources is used and each
has different physical characteristics that can affect the success of the compaction. This study aims to analyze
and compare the results of material compaction from four different quarries using the field density test (sand
cone) and laboratory carrying capacity test (CBR) methods. The research methodology includes the analysis of
physical characteristics such as particle size distribution and sludge content. and compaction quality testing after
being given the same number of Vibratory Roller passes for each material. The results showed that the material
from Quarry A achieved the highest average field density (104.71%), which indicated the highest compaction
effectiveness among other materials. In terms of carrying capacity, the material from Quarry B proved to be the
most superior, with the highest CBR value both in dry conditions (103.00%) and after submersion (58.00%). In
contrast, Quarry C material showed the highest sensitivity to water, its CBR value decreased from 75.00% to
27.00% when submerged, which correlated with the highest silt content (9.21%). These findings prove that the
physical characteristics of materials, such as silt content and grain size distribution are the main determining
factors that affect the final yield of soil density and carrying capacity. This research produces technical
recommendations in the selection of reclamation materials to ensure the achievement of compaction quality
targets that are in accordance with project conditions and needs.
