Abstract

Telah dilakukan analisis sifat fisis dan ketahanan terhadap natrium sulfat paving block dengan variasi serbuk cangkang langkitang dan penambahan serat ijuk. Persentase serbuk cangkang langkitang  yang digunakan dalam agregat halus yaitu 0%,10%, dan 20%. Persentase serat  yang digunakan sebagai bahan tambahan sebesar  0%, 1%, 3%, dan 4% dengan penyusunan serat secara acak (randomly oriented). Pengujian yang dilakukan yaitu uji sifat fisis berupa kuat tekan, kuat lentur, daya serap air dan pengujian ketahanan terhadap natrium sulfat. Pengujian dilakukan setelah paving  block berumur  28 hari. Kuat tekan dan kuat lentur diuji menggunakan Universal Testing Machine (UTM) PP 24-1283. Kuat tekan tertinggi sebesar 18,500 kN diperoleh pada paving block dengan persentase serbuk cangkang langkitang 20% dan serat ijuk 10%. Kuat lentur tertinggi diperoleh pada sampel dengan persentase serbuk cangkang langkitang 10% dan ijuk 1% dan 3% dan serbuk cangkang 20% serat ijuk 4%. Daya serap air rerata terendah sebesar 0,0033% dengan persentase serbuk cangkang langkitang 0% dan serat ijuk 3%. Kehilangan massa terbesar paving block setelah direndam menggunakan natrium sulfat terjadi pada persentase serbuk cangkang langkitang 20%. Penggunaan serbuk cangkang langkitang sebagai agregat pengganti pasir menyebabkan penurunan kuat tekan paving block,  namun ketika serbuk cangkang langkitang digunakan sebagai agregat tambahan mampu meningkatkan kuat tekan paving block. Berdasarkan kuat tekannya rata-rata paving block yang  dibuat memenuhi standar mutu C hingga mutu B SNI 3-0691-1996.

Kata kunci: paving block, cangkang langkitang, serat ijuk, kuat tekan, kuat lentur, uji natrium sulfat, daya serap.
