Latar belakang: PT Beton Elemenindo Perkasa merupakan industri yang bergerak di bidang konstruksi. Salah satu sampah yang dihasilkan PT Beton Elemenindo Perkasa adalah sampah polistirena foam yang pengolahannya masih dilakukan dengan pembakaran terbuka sehingga berdampak pada kesehatan dan penurunan kualitas lingkungan. Pembakaran sampah polistera foam menghasilkan gas berbahaya seperti styrene, hydrochloroflourocarbon (HCFC), polycyclic aromatic hydrocarbons (PAHs), carbon black serta karbon monoksida. Salah satu teknologi pengolahan sampah polisterana foam adalah dengan membuat tungku pembakaran yang dilengkapi media filter karbon. Karbon aktif merupakan salah satu media filter udara yang dapat menyerap gas berbahaya dari proses pembakaran. Tujuan penelitian ini adalah untuk mengetahui efektivitas penurunan konsentrasi karbon monoksida (CO) dengan sistem kontak media karbon aktif menggunakan variasi ukuran partikel.Metode: Penelitian ini merupakan jenis penelitian eksperimen dengan desain post test with control. Jumlah sampel dihitung berdasarkan banyaknya perlakuan dan jumlah pengulangan dalam penelitian. Penelitian ini menggunakan 2 macam perlakuan 20 mesh dan 30 mesh didapatkan 9 kali pengulangan.Hasil: Analisis statistik Independent T-Test menunjukkan ada perbedaan yang bermakna (p-value=0,001) pada variasi ukuran partikel karbon aktif terhadap paramater karbon monoksida (CO).Simpulan: Rata-rata persentase penurunan paling efektif pada ukuran partikel karbon aktif 30 mesh sebesar 77,95%. ABSTRACTTitle: Effectiveness of Carbon Monoxide (CO) Concentration Reduction on Active Carbon Contact System Using Particle Size Variation in Burning Process of Polystyrene FoamBackground:PT Beton Elemenindo Perkasa is an industry engaged in construction. One of the wastesgenerated by PT Beton Elemenindo Perkasa is polystyrene foam waste, its processing of which is still done with open burning so it has impact on health and environmental quality degradation. Burning polystyrene foamwaste produces harmful gases such as styrene, hydrochloroflourocarbon (HCFC), polycyclic aromatic hydrocarbons (PAHs), carbon black, and carbon monoxide. One of the polystyrene foam waste processing technologies is by making a combustion furnace equipped with carbon filter. Activated carbon is one of the air filter media that can absorb harmful gas from the combustion process. The purpose of this research is to identify the effectiveness of carbon monoxide (CO) concentration reduction on active carbon contact system using variation of particle size.Method: This research is a kind of experimental study with post test with control design. The number of samples was calculated based on the number of treatments and the number of repetitions in the study. This research used 2 kinds of treatment which were 20 mesh and 30 mesh and got 9 repetitions.Result:Independent T-Test statistical analysis showed a significant difference (p-value = 0.001) between the variation of particle size of activated carbon and carbon monoxide (CO) parametersConclusion:Average of the most effective reduction percentage onparticle-sized active carbon of 30 mesh was 77.95%.
