Abstract

Penelitian ini berjudul “Pengaruh Variasi Konsentrasi Graphene Oxide sebagai Zat Aditif terhadap Kekuatan Tekan Beton K-300” Penelitian ini bertujuan untuk mengetahui karakteristik graphene oxide (GO) komersial, mengevaluasi pengaruh variasi konsentrasinya terhadap kekuatan tekan beton K-300, serta mengidentifikasi konsentrasi optimal GO yang mampu meningkatkan sifat mekanis beton secara maksimal. Beton merupakan material konstruksi yang banyak digunakan karena kekuatan tekan dan durabilitasnya yang tinggi. Namun, sifatnya yang rapuh membatasi kemampuannya dalam menahan lentur dan tegangan. Penambahan graphene oxide, material nano dengan luas permukaan besar dan sifat kimia unik, diharapkan dapat meningkatkan performa beton melalui perbaikan struktur mikro, pengurangan porositas, dan peningkatan kekuatan mekanik. Metode penelitian yang digunakan adalah eksperimen laboratorium, di mana variasi konsentrasi GO (0%, 0,1%, hingga 1%) ditambahkan pada campuran beton K-300. Beton diuji kekuatan tekannya pada umur 28 hari menggunakan mesin uji tekan sesuai standar SNI. Hasil penelitian menunjukkan bahwa penambahan GO sebesar 0,5% memberikan peningkatan kekuatan tekan maksimal hingga 30 N/mm² dibandingkan kontrol sebesar 27 N/mm². Namun, penambahan GO di atas konsentrasi optimal menyebabkan penurunan performa beton akibat aglomerasi partikel GO. Kesimpulan dari penelitian ini adalah penambahan graphene oxide dapat secara signifikan meningkatkan kekuatan tekan beton pada konsentrasi optimal, tetapi penggunaannya memerlukan kontrol yang tepat untuk menghindari efek negatif. Penelitian ini memberikan kontribusi penting dalam pengembangan material konstruksi yang lebih kuat dan ramah lingkungan.

This study, titled "The Effect of Graphene Oxide Concentration Variations as an Additive on the Compressive Strength of K-300 Concrete," aims to characterize commercial graphene oxide (GO), evaluate the influence of its concentration variations on the compressive strength of K-300 concrete, and identify the optimal GO concentration to maximize the mechanical properties of the concrete. Concrete is widely used in construction due to its high compressive strength and durability. However, its brittle nature limits its ability to withstand bending and tension. The addition of graphene oxide, a nanomaterial with a large surface area and unique chemical properties, is expected to enhance concrete performance by improving microstructure, reducing porosity, and increasing mechanical strength. The research method involved laboratory experiments where GO concentrations (0%, 0.1%, up to 1%) were added to K-300 concrete mixtures. The compressive strength of the concrete was tested at 28 days using a compression testing machine in accordance with SNI standards. The results indicated that the addition of 0.5% GO achieved the highest compressive strength of 30 N/mm², compared to the control's 27 N/mm². However, exceeding the optimal concentration led to a decline in concrete performance due to GO particle agglomeration. This study concludes that adding graphene oxide can significantly enhance the compressive strength of concrete at optimal concentrations, but precise control is required to avoid negative effects. This research contributes significantly to the development of stronger and more environmentally friendly construction materials.
