%T PENGARUH PENAMBAHAN PASIR DAN SEMEN TERHADAP KUAT TEKAN PAVING BLOCK MATERIAL TANAH MENGGUNAKAN ALAT PEMADAT MODIFIKASI
%X ABSTRAK

Paving block terbuat dari campuran semen portland atau bahan perekat hidrolis sejenisnya, air, dan agregat dengan atau tanpa bahan lainnya.  Pada penelitian ini paving block dibuat menggunakan campuran tanah, semen dan pasir.  Dalam pembuatan paving block digunakan alat pemadat modifikasi yang diharapkan dapat meningkatkan mutu paving block yang sesuai SNI 03-0691-1996. 

Sampel tanah yang diuji berasal dari daerah Kota Baru, Lampung Selatan.  Variasi campuran yang digunakan dalam penelitian ini adalah dengan menambahkan pasir sebanyak 2%, 4%, 6%, 8%, dan 10% dan menambahkan semen sebanyak 3%, 6%, 9%, 12%, dan 15% serta dengan perlakuan pra pembakaran dan pasca pembakaran sampel paving block.  

Hasil pengujian kuat tekan terhadap paving block yang dibuat dengan campuran tanah, semen dan pasir telah memenuhi standar SNI 03-0691-1996 untuk klasifikasi paving block mutu D yang dapat digunakan untuk taman.  Proses pembakaran paving block hanya memberikan kenaikan sedikit terhadap paving block tanpa proses pembakaran.  Nilai kuat tekan tertinggi dihasilkan oleh paving block pasca pembakaran pada variasi campuran 10% pasir + 15% semen + 75% tanah sebesar 10,05 MPa.  Sedangkan nilai uji daya serap yang dihasilkan berkisar antara 16,6% ? 23,8% sehingga tidak memenuhi standar SNI 03-0691-1996.

ABSTRACT

Paving blocks made from mixture of portland cement or other hydrolysis adhesive, water, and aggregates with or without other materials. In this study, paving blocks are made by using a mixture of soil, portland cement and sand. In the manufacture of paving blocks used compactor modification that are expected to increase the strength of paving blocks that according to SNI 03-0691-1996.

Soil samples tested were from Kota Baru, South Lampung. The variation of mixture that used in this study is by adding sand as much as 2%, 4%, 6%, 8%, and 10% and add cement as much as 3%, 6%, 9%, 12%, dan 15% as well as with the treatment of pre-combustion and post-combustion of the sample of paving blocks. 

Results of testing the compressive strength of the paving blocks with a mixture of soil , cement and sand has meet the standard of SNI 03-0691-1996 for the classification of paving blocks quality D which can be used for garden.  The combustion process of paving blocks is giving only slightly against the increase in paving blocks without the process of combustion.  The highest compressive strength value generated by post-combustion of paving blocks on the variation of mixture 10 % sand + 15 % cement + 75 % soil amounted to 10.05 MPa .  While the value of the water absorption test ranged from 16.6 % - 23.8 % so it does not meet the standard of SNI 03-0691-1996 .



Keywords: Paving blocks, silt soil, compressive strength, water absorption.
