Abstract

Telah dilakukan penelitian tentang pemanfaatan serat sabut pinang sebagai filler pada beton ringan berkatalis MEKPO. Penelitian ini bertujuan untuk menganalisis pengaruh variasi massa serat sabut pinang terhadap sifat fisik dan mekanik beton ringan. Persentase serat sabut pinang yang digunakan adalah 0%, 0,2%, 0,4%, 0,6%, dan 0,8%. Sifat fisik yang diuji berupa densitas, porositas dan daya serap air dengan ukuran sampel 5 x 5 x 1 cm, sedangkan uji sifat mekanik berupa kuat tekan dan kuat lentur dengan menggunakan sampel berukuran 20 x 5 x 1 cm. Pengujian sifat mekanik dilakukan dengan mengguanakn universal testing machine (UTM). Berdasarkan hasil pengujian, penambahan massa serat sabut pinang berbanding terbalik dengan densitas dan berbanding lurus dengan porositas dan daya serap air. Nilai densitas terendah sebesar 1,58 g/cm3 dengan komposisi serat sebanyak 0,8%, nilai porositas terendah yaitu sebesar 15,3% dengan komposisi serat 0%, dan nilai daya serap air terendah sebesar 9,47% pada komposisi serat 0%. Nilai kuat tekan tertinggi pada penambahan serat yaitu sebesar 33,46 kg/cm3 dengan komposisi serat 0,8%, sedangkan nilai kuat lentur tertinggi sebesar 24 kg/cm3 dengan komposisi serat 0,8%. Semakin banyak serat yang digunakan nilai kuat tekan dan kuat lentur juga meningkat. Nilai densitas, porositas, daya serap air dan kuat lentur papan beton ringan berserat sabut pinang telah memenuhi strandar SNI 03-2105-2006 dan SNI 03-2104-1991 namun kuat tekan belum memenuhi standar.
