Abstract

Penggunaan beton dan mortar dalam dunia kemaritiman memiliki peran penting, namun permasalahan fouling sering menjadi kendala yang signifikan. Cat antifouling yang lazim digunakan terbukti berbahaya bagi lingkungan, sehingga diperlukan alternatif yang lebih ramah lingkungan. Penelitian ini bertujuan untuk mengkaji dan membandingkan sifat mekanik serta kemampuan fouling dari mortar dengan campuran nano silika pada variasi 3%, 5%, dan 7%, dibandingkan dengan mortar normal.Metode penelitian meliputi uji tekan berdasarkan standar SNI, uji porositas, uji daya serap air, dan evaluasi fouling. Hasil analisis menunjukkan bahwa mortar dengan campuran 3% nano silika memiliki performa terbaik dalam sifat mekanik dan daya tahan terhadap fouling. Pada uji tekan, rata-rata kuat tekan tertinggi dicapai oleh mortar dengan campuran 3% nano silika sebesar 27,9 MPa, diikuti oleh mortar 5% nano silika (23 MPa), mortar normal (21 MPa), dan mortar 7% nano silika (17,27 MPa). Hasil uji porositas menunjukkan nilai P(%) mortar +3% nano silika sebesar 15,152%, lebih kecil dibandingkan mortar normal (16,877%), sehingga lebih tahan terhadap fouling. Dalam uji daya serap air, mortar dengan tambahan nano silika membutuhkan waktu 4 menit lebih lama untuk menyerap air dibandingkan mortar normal. Hasil uji fouling dapat dilihat secara kasat mata mengungkapkan bahwa mortar dengan 3% nano silika memiliki pertumbugan fouling paling sedikit dibandingkan variasi lainnya. Kesimpulan dari penelitian ini adalah bahwa campuran nano silika sebesar 3% pada mortar memberikan sifat mekanik terbaik dan daya tahan fouling yang paling efektif, sehingga memiliki potensi untuk diterapkan sebagai solusi ramah lingkungan dalam dunia kemaritiman.

The use of concrete and mortar plays a significant role in the maritime sector; however, fouling problems often become a major challenge. Commonly used antifouling paints have been proven to harm the environment, highlighting the need for more eco-friendly alternatives. This study aims to examine and compare the mechanical properties and fouling resistance of mortar mixed with nano silica at variations of 3%, 5%, and 7%, compared to normal mortar. The research methods included compressive strength tests based on SNI standards, porosity tests, water absorption tests, and fouling evaluations. The analysis results showed that mortar with 3% nano silica exhibited the best performance in terms of mechanical properties and fouling resistance. In the compressive strength test, the highest average strength was achieved by mortar with 3% nano silica at 27.9 MPa, followed by 5% nano silica mortar (23 MPa), normal mortar (21 MPa), and 7% nano silica mortar (17.27 MPa). The porosity test results revealed that the P(%) value for 3% nano silica mortar was 15.152%, smaller than that of normal mortar (16.877%), indicating better resistance to fouling. In the water absorption test, mortar with nano silica required 4 minutes longer to absorb water compared to normal mortar. The fouling evaluation, observed visually, indicated that 3% nano silica mortar had the least fouling growth compared to the other variations. In conclusion, mortar with 3% nano silica provides the best mechanical properties and fouling resistance, making it a promising eco-friendly solution for applications in the maritime sector.
