Abstract

Salah satu industri gula memproduksi abu ampas tebu dalam jumlah yang banyak. Abu ampas tebu pada industri gula tersebut belum dapat dimanfaatkan. Abu ampas tebu memiliki kandungan silika yang cukup tinggi yakni sebesar 68,5% dapat dimanfaatkan sebagai bahan pengganti untuk mengurangi penggunaan semen pada pembuatan paving block. Pada penelitian ini pembuatan batu bata beton menggunakan metode pressing manual. Paving block terbuat dari pasir, semen, abu ampas tebu, abu batu dan air. Perbandingan semen, abu batu dan pasir menggunakan perbandingan 1:2:6 dengan variasi abu ampas tebu 10, 20 dan 30%. Hasil pengujian didapatkan batu bata beton mutu tertinggi pada pengeringan hari ke-7 dengan 214 kg/cm2 mendapatkan mutu B berdasarkan SNI 03-0691-1996 dan kuat tekan batu bata beton yang dihasilkan akan semakin meningkat seiring bertambahnya waktu pengeringan. Inovasi ini dapat meningkatkan kegunaan pada abu ampas tebu dan menjadi peluang bisnis baru untuk industri gula.

Abstract

One of the sugar industries produces large quantities of bagasse ash. Sugarcane bagasse ash in the sugar industry cannot yet be utilized. Sugarcane bagasse ash has a relatively high silica content, namely 68.5%, which can be used as a substitute material to reduce the use of cement in making paving blocks. In this research, concrete bricks were made using the manual pressing method. Paving blocks are made from sand, cement, bagasse ash, stone ash, and water. The cement, stone ash, and sand ratio is 1:2:6, with variations in bagasse ash of 10, 20, and 30% of the sand composition. The test results showed that the highest quality concrete bricks were on the 7th day of drying, with 214 kg/cm2, getting quality B based on SNI 03-0691-1996, and the compressive strength of the resulting concrete bricks would increase as the drying time increased. This innovation can improve the usability of bagasse ash and become a new business opportunity for the sugar industry.
