PEMANFAATAN SPENT CATALYST RCC 15 LIMBAH PERTAMINA SEBAGAI BAHAN TAMBAH PADA CAMPURAN BETON

The utilization of spent catalyst of RCC 15 pertamina waste as an additive ingredient on a concrete mix. The Residual Spent Catalyst Catalyst Cracking (RCC) 15 is a waste of processing crude oil in the reactor. Recycling waste into a useful material is a solution to reduce waste pollution. The purpose of this study to determine the compressive-strength of concrete by varying the Spent Catalyst RCC 15 added. This study uses experimental designs by adding Spent Catalyst RCC 15 by 15%, 20%, 25%, and 30% of the weight of cement, in which 20 specimens are used in each group. The results show that more Spent Catalyst RCC 15 added to the concrete mix results in higher compressive strength. Spent Catalyst Residual Cracking Catalyst (RCC) 15 merupakan limbah dari pemrosesan minyak mentah didalam reactor. Pemakaian limbah menjadi bahan yang berfungsi merupakan suatu langkah untuk mengatasi pencemaran limbah. Tujuan penelitian ini untuk mengetahui kuat tekan beton dari variasi penambahan Spent Catalyst RCC 15. Penelitian ini menggunakan rancangan eksperimen dari penambahan Spent Catalyst RCC 15 sebanyak 15%, 20%, 25%, dan 30% dari berat semen, dengan benda uji 20 buah pada masing-masing kelompok. Hasil penelitian menunjukkan bahwa semakin banyak kadar Spent Catalyst RCC 15 yang ditambah­kan pada campuran beton maka kuat tekannya makin besar.
