Abstrak

Penelitian ini bertujuan untuk mengetahui pengaruh sekam padi terhadap kuat tekan dan penyerapan redam suara pada batako sekam padi tersebut. Metode penelitian yang digunakan adalah metode padatan. Sampel sebanyak 21 batako berbentuk silinder dengan diameter 5cm dan tinggi 4cm. Variasi Semen 10%, 20% dan 30% dengan persentase volume. Bahan pengisinya berupa pasir 80-10% dan sekam 10-80% dengan jumlah total 100%. Karakterisasi dilakukan berupa uji fisis yaitu densitas, porositas dan uji mekanis yaitu uji kuat tekan, uji redam dan konduktivitas termal. Hasil uji karakterisasi densitas sebesar 1.13-1.77gr/cm3. Densitas yang paling besar adalah sampel S30SP10 yaitu 1.77gr/cm3. Nilai porositas 6.39-46.55%. Uji kuat tekan antara 0.43-12.84Mpa. Kuat tekan yang paling besar adalah sampel S30SP10 karena kandungan semen yang besar sehingga memperkuat beton ringan tersebut. Uji redam suara tertinggi pada sampel S30SP60 dengan penyerapan sebesar 0.44. Selanjutnya uji konduktivitas termal dilakukan pada sampel S10SP80, S30SP40, S30SP50 dengan data hasil yaitu 0.81, 0.93,1.09W/moK. Kata kunci : Batako beton ringan, Metode padatan, Uji fisis, Uji mekanis. (Abstract. This study aimed to determine the effect ofrice husk against compressive strengt hand absorption of sound damping in the rice husk brick. The method used is the method of solids. Sample of 21brick-shaped cylinder with a diameter of 5cm and 4 cm high. Cement variation of 10%, 20% and 30% by volume percentage. Filler material such as sand, and chaff 80-10% 10-80% with a total of 100%. Characterization was done by testing the physical density, porosity and mechanical tests that test compressive strength, damping test and thermal conductivity. Characterization test results density is 1.13-1.77gr/cm3. Density is greatest S30SP10 sample is 1.77gr/cm3. Porosity values between 6.39-46.55%. Compressive strength test between 0.43-12.84MPa. Compressive streng this greatest S30SP10 sample because the cement content of the concreterein for cing the mild. Highest sound damping test on samples with absorption at 0.42 S30SP60. Further thermal conductivity test performed on a sample S10SP80, S20SP70, S30SP60 with the that is 0.84, 1.01,1.04 W/moK. Keywords. rice husk, solid method, the percentage of volume, characterization.)
