Abstract

Soil compaction is an important process in reclamation work because it has a direct effect on the carrying capacity and stability of the structure built on it. This study was conducted in one of the specific work zones of Area C1a in the Patimban Port reclamation project, where sand material from various quarry sources is used, each having different physical characteristics that can affect the success of 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, as well as compaction quality testing after applying the same number of vibratory roller passes to each material. The results showed that the material from Quarry A achieved the highest average field density (104.71%), indicating the highest compaction effectiveness among the materials tested. 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%), after submersion (58.00%). In contrast, the Quarry C material showed the highest sensitivity to water, as its CBR value decreased from 75.00% to 27.00% when submerged, which correlated with the highest silt content (9.21%). These findings demonstrate that the physical characteristics of materials, such as silt content and grain size distribution, are the main determining factors affecting the final yield of soil density and carrying capacity.

Abstract

Abstract: Background: Community service is one aspect of the Tri Dharma of Higher Education that contributes to social, economic, and educational development. Aim: The Thematic Community Service Program (KKN-T) aims to build the independence of the Ciledug Wetan Village community through education-based, economic, and social empowerment. Methods: This activity uses the Participation Action Research (PAR) method, which emphasizes the community's active involvement at every stage of the program, from problem identification to planning, implementation, and evaluation. Results: The activities show increased children's literacy through interactive storytelling activities, encouraging their reading interest and critical thinking. In the economic aspect, MSME actors received training in branding, digital marketing, and promotional material creation to enhance the competitiveness of local products. In addition, public awareness of environmental cleanliness has increased through education on clean and healthy living behaviors (PHBS) and the management of organic and inorganic waste. Conclusions: This program has a direct impact on the community and students through knowledge application, leadership development, and the enhancement of communication and collaboration skills. Implication: These results affirm that student involvement in community-based empowerment programs can be an effective strategy for supporting sustainable development and innovation based on local wisdom.
