dc.description.abstractArang aktif biasa dipakai dalam proses pemurnian udara, gas, larutan atau cairan, dan proses perolehan kembali suatu logam. Arang aktif memiliki pori-pori yang lebih terbuka sehingga daya jerapnya lebih tinggi dibandingkan arang biasa. Bahan yang dapat digunakan sebagai bahan baku arang aktif adalah limbah perkebunan seperti tempurung kluwak, kelapa sawit, kelapa, dan kemiri. Penelitian ini bertujuan membandingkan arang aktif dengan mutu terbaik dari bahan dasar tempurung untuk menurunkan kadar gas pencemar udara seperti gas CO, NO2, dan SO2 yang berasal dari emisi kendaraan bermotor yang dapat merusak lingkungan dengan metode kajian literatur. Hasil penelitian menunjukkan keempat tempurung menghasilkan arang aktif dengan mutu yang baik. Tempurung kluwak menghasilkan arang aktif dengan kandungan karbon terikat tertinggi, yaitu sebesar 96,90% serta daya jerap iod sebesar 996,96 mg/g yang memenuhi SNI 06-3730-1995. Arang aktif tempurung kluwak memiliki efektivitas terhadap penurunan konsentrasi gas CO yang paling baik, yaitu sebesar 98,02%, sedangkan efektivitas terhadap penurunan konsentrasi gas NO2 dan SO2 yang paling baik dimiliki oleh arang aktif tempurung kelapa, yaitu 93,50% terhadap gas NO2 dan 76,79% terhadap gas SO2. Kata kunci: adsorpsi, arang aktif, emisi, karbon terikat, tempurungid
dc.description.abstractActivated charcoal is commonly used to purify air, gas, solution, or liquid, and recover a metal. Activated charcoal has pores that are more open so that it has a higher adsorption capacity than ordinary charcoal. Raw materials used as activated charcoal include leftover shell from kluwak, palm kernel, coconut, and candlenut shell. This study compares and determines which shell-based activated charcoal has the best quality to reduce air pollutant gases such as CO, NO2, and SO2 gases from motor vehicle emissions that can damage the environment using a literature review method. The results showed that the four shells produced good quality activated charcoal. Kluwak shell produces activated charcoal with the highest fixed carbon content, 96.90% and iodine adsorption capacity of 996.96 mg/g, complying with SNI 06-3730-1995. Kluwak shell activated charcoal has the most excellent effectiveness in reducing the concentration of CO gas from motor vehicle emissions compared to activated charcoal from the other three shell types, which is 98.02%. Meanwhile, coconut shell-activated charcoal performs the best effectiveness in reducing NO2 and SO2 gas concentrations, which has 93.50% for NO2 and 76.79% for SO2.
