Abstract

ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh media adsorben terhadap adsorpsi emisi gas CO pada kendaraan bermotor dan kondisi optimal efisiensi penurunan gas CO dengan variasi rasio persentase arang aktif ampas kopi dan batok kelapa, ukuran arang aktif, jumlah penambahan TiO2. Variasi-variasi tersebut disusun berdasarkan rancangan Box-Behnken. Hasil penelitian menunjukkan jumlah penambahan TiO2 pada media adsorben berpengaruh paling signifikan, kemudian ukuran arang aktif, dan terakhir persentase arang aktif ampas kopi dan batok kelapa. Peningkatan efisiensi penurunan gas CO terjadi seiring persentase arang aktif ampas kopi bertambah dan batok kelapa berkurang, semakin kecilnya ukuran arang aktif, dan semakin besar jumlah penambahan TiO2. Efisiensi penurunan gas CO kondisi optimal sebesar 74,34% dicapai pada media adsorben dengan persentase arang aktif ampas kopi 100% dan batok kelapa 0%, ukuran arang aktif 80 mesh, dan jumlah penambahan TiO2 20%. Kata kunci : Adsorpsi, arang aktif, ukuran arang aktif, TiO2, CO, desain Box-Behnken ABSTRACT This research aims to determine the effect of adsorbent media on CO gas emission adsorption on motorized vehicles and the optimal conditions for reducing CO gas by varying the ratio of the percentage of activated charcoal from coffee grounds and coconut shells, the size of activated charcoal, the amount of TiO2 addition. These variations are arranged based on the Box-Behnken design. The results showed the amount of addition of TiO2 on the adsorbent media had the most significant effect, then the size of activated charcoal, and finally the percentage of activated charcoal from coffee grounds and coconut shells. The increase in efficiency of CO gas reduction occurs as the percentage of activated charcoal from coffee grounds increases and the coconut shell decreases, the smaller the size of the activated charcoal, and the greater the number of TiO2 additions. The optimal efficiency of CO gas reduction is 74.34%, achieved on adsorbent media with 100% coffee grounds activated charcoal percentage and 0% coconut shell, 80 mesh activated charcoal size, and 20% TiO2 addition. Keywords: Adsorption, activated charcoal, activated charcoal size, TiO2, CO, Box-Behnken design
