Abstract

Kereta api adalah jenis transportasi darat yang banyak digunakan oleh masyarakat di penjuru dunia. Salah satu komponen yang penting yaitu komponen lantai kereta api. Adapun pelapis lantai kereta api jenis KRD dan KRL adalah material cork concrete yaitu komposit matriks polimer dengan penguat berupa agregat kasar. Penelitian ini menganalisis pengaruh variasi komposisi agregat yang berasal dari Tuban terhadap sifat mekanik yang sesuai dengan standar. Adapun matriksnya terbuat dari resin epoxy dan berpenguat partikel berupa agregat Tuban yang dicampur dengan agregat Puskim. Dari penelitian yang dilakukan disimpulkan bahwa semakin tinggi komposisi agregat Tuban maka sifat mekanik komposit akan semakin semakin meningkat karena pencampuran agregat Tuban dan Puskim dapat meningkatkan sifat mekaniknya karena dapat diprediksi sifat fisiknya melalui teori pencampuran (Rule of Mixture). Nilai maksimum didapat pada material komposit pada komposisi agregat 60%Tuban-40%Puskim dengan kuat tekan 68,02 MPa, dan kuat lentur 6,29 MPa. Bentuk dan komposisi agregat sangat mempengaruhi sifat fisik, apabila dengan komposisi berbeda dan jenis material yang berbeda maka sifat dan karakteristik material akan berbeda pula dengan pengamatan secara visual dengan mikroskop stereo, dan FTIR yang telah dilakukan =============================================================================================== Train is a type of land transportation that is widely used by people throughout the world. One of important component is the component of the train floor. The KRD and KRL train floor construction are made by polymer matrix composites with large particle reinforcements by coarse aggregates that called as cork concrete materials. This research analyzes the effect of variations in aggregate composition originating from Tuban on mechanical properties that appropriate to the standard. The matrix is made of epoxy resin and reinforced by Tuban aggregates mixed with Puskim aggregates. From the research, was concluded that the higher of Tuban aggregate composition of, the mechanical properties of composites will increase as the aggregate mixing of Tuban and Puskim can improve its mechanical properties because it is predicted by its physical properties through the Rule of Mixture theory. The maximum value is obtained on the composite material which contains aggregate composition of 60% Tuban-40% Puskim with compressive strength of 68.02 MPa, and flexural strength of 6.29 MPa. The geometry and composition of the aggregate greatly affects the physical properties, if it has different compositions and different types of material, the properties and characteristics of the material will become different from visual observations with microscope, and FTIR.
