Abstract

This research presents resulf of changes material of Municipal Solid Waste (MSW) embankments by decomposition process on engineering properties and shear strength parameters. It can be grouped by three cluster which has determined by ages of MSW. This research located on Piyungan MSW Embankment Yogyakarta. In situ test by standard penetration tests (SPT) and material sampling by test pit. The objective is to analyses the characterizations of engineering properties and shear strength parameter due to decomposition process. Engineering properties was determined by unit weight, water content, organic content and specific gravity. Also Shear strength parameter was determined by Triaxial test. Unit weight increased from the fresh embankment to the oldest embankment about 20.4%, also the results of shear strength parameter showed that cohesion value increased about 26.8% and the results of friction angles value increased about 9.8%. The due to decomposition process on MSW embankment which has the oldest embankment can be decomposed to improve engineering properties and shear strength parameter more than the fresh MSW embankment. Decomposition effects was indicated by organic content has been decreased about 35.6% from the fresh of MSW embankment to the oldest embankment. In accordance with the result of the laboratory analyses could be influence the slope stability analysis of waste embankment.
