Abstract
Sawdust waste from the furniture industry should be considered. Nowadays, the increased demand for furniture is in line with the increase in sawdust waste produced. Therefore, it is necessary to make use of sawdust to protect environment. An alternative use is the addition of sawdust as the concrete mixture. Cellulose and hemicellulose compounds are compounds contained in wood powder, where these compounds can provide additional bonding between particles in the cement and sand mixture in concrete. Therefore, concrete can be stronger as well as more water resistant, hence it can be used for a specific purpose in constructions. This study aims to analyze the compressive strength of concrete due to the addition of sawdust as an organic fiber in the concrete mixture with the percentage of 0.25%, 0.50%, 0.75% and 1% as substitution of sand. Organic fibers as additives in concrete are being developed until recently. The proposed concrete was 25 MPa quality. Result showed the increase in the compressive strength of concrete by 0.98% in 1% wood powder mixed at 28 days of concrete age.

Summary
Serbuk kayu yang merupakan hasil limbah dari industri furniture menjadi salah satu yang harus diperhatikan. Peningkatan pemintaan furniture seiring dengan peningkatan limbah serbuk kayu yang dihasilkan. Penambahan serbuk kayu kedalam campuran beton merupakan salah satu alternatifnya. Senyawa selulosa serta hemiselulosa merupakan senyawa yang terkandung dalam serbuk kayu, dimana senyawa ini dapat memberikan penambahan ikatan antar partikel pada campuran semen dan pasir pada beton. Oleh karena itu beton dapat menjadi lebih kuat dan relative lebih tahan terhadap air sehingga dapat dipakai pada konstruksi yang memiliki tujuan tertentu. Penelitian bertujuan untuk menganalisis kuat tekan beton dikarenakan adanya penambahan serbuk kayu sebagai serat organik dalam campuran beton dengan prosentase 0,25%, 0,50%, 0,75% dan 1% substitusi terhadap pasir. Beton rencana yang akan digunakan adalah mutu 25 MPa. Peningkatan kuat tekan beton sebesar 0,98% pada beton campuran 1% serbuk kayu dihasilkan pada umur beton 28 hari
