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%.

ABSTRACT   Carbon Monoxide (CO) produced from smoke by cigarettes has a certain level that accumulates indoors and affects indoor air quality. The purpose of this study was to see how effective the method of air stripping in reducing CO gas concentration by using activated carbon, silica sand, and zeolite media in the experimental room which has a volume of 1000 litters. This research was performed in the laboratory by using pre-experiment random group design. The independent variables of this study include activated carbon, zeolite, and silica sand as adsorbent, while the dependent variable of this study was carbon monoxide concentration. The test was carried out by measuring the accumulation of CO gas from burning cigarette, and subsequent testing with air stripping test treatment by using the varies adsorbent on 30 minutes. From the test results obtained the highest percentage reduction of CO concentration, which was 50.89% by using the activated carbon adsorbent medium, and the lowest percentage of CO reduction was 5.85% by using silica sand adsorbent medium. The difference of CO gas concentration was significant after passing air stripping process by using zeolite media, activated carbon and silica sand with significance level p value = 0.0001. There were significant differences in the ability of zeolite, activated carbon and silica sand to reduce CO concentration, with p value = 0.0001.   Keywords: Carbon Monoxide Concentration, Air Stripping, Adsorption, Activated Carbon, Zeolite, Silica Sand   ABSTRAK   Karbon Monoksida (CO) yang dihasilkan dari asap oleh rokok memiliki kadar tertentu yang terakumulasi di dalam ruangan dan mempengaruhi kualitas udara dalam ruangan.

Penelitian ini merupakan penelitian yang dilakukan di dalam laboratorium dengan menggunakan pre-eksperimen desain kelompok acak. Variabel bebas dari penelitian ini meliputi karbon aktif, pasir zeolite dan pasir silika sebagai adsorben, sedangkan variabel terikat dari penelitian ini konsentrasi karbon monoksida.. Pengujian dilakukan dengan mengukur akumulasi gas CO dari pembakaran rokok, dan pengujian berikutnya dengan perlakuan uji air stripping menggunakan adsorben yang berbeda-beda dengan waktu pengujian selama 30 menit. Dari hasil uji didapatkan persentase penurunan konsentrasi CO tertinggi, yaitu 50,89 % dengan menggunakan media adsorben karbon aktif, dan persentase penurunan CO terendah yaitu 5,85% dengan menggunakan media adsorben pasir silika. Perbedaan konsentrasi gas CO yang signifikan setelah melalui proses air stripping dengan menggunakan media zeolit, karbon aktif dan pasir silika dengan taraf signifikasi nilai p = 0,0001. Ada perbedaan nilai yang signifikan terhadap kemampuan media zeolit, karbon aktif dan pasir silika dalam menurunkan konsentrasi CO, dengan nilai p = 0,0001.   Kata kunci : Konsentrasi Karbon Monoksida, Air Stripping, Adsorbsi, Karbon aktif, Zeolit, pasir silika

Abstract This paper presents the results of the possibility and effectiveness of PAHs removal from a model aqueous solution, during the sorption on the selected sorbents. Six PAHs (naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene) listed by EPA for the analysis in the environmental samples were determined. Model aqueous solution was prepared with RESTEK 610 mix PAHs standard. After the sorption process, decrease in the concentration of individual hydrocarbons was observed. The removal percentage was dependent on the type of sorbent (quartz sand, mineral sorbent, activated carbon). The highest efficiency (98.1%) was observed for activated carbon.. The results shows that the sorption processes can be used in aqueous solutions treatment procedures.
