AbstrakPenelitian ini bertujuan untuk mengetahui pengaruh jenis aktivator dan ukuran partikel terhadap karakteristik karbon aktif dari serbuk gergaji kayu sengon (Paraserianthes falcataria). Karakteristik karbon aktif perlu dilakukan pengujian untuk mengetahui kualitas adsroben, pengujian tersebut meliputi uji kadar air, kadar abu, daya serap terhadap iodin, dan BET (Braunanear, Emmelt, dan Teller). Serbuk kayu sengon yang telah dihaluskan kemudian diayak mengunakan variasi -20,+40, -40,+60, -60,+80, -80,+100 mesh. Proses karbonisasi dilakukan pada suhu 500°C selama 30 menit. Pembuatan karbon aktif diaktivasi menggunakan aktivator H3PO4, NaOH, dan NaCl dengan konsentrasi masing-masing 0,1 M dalam 100 mL. Proses aktivasi dilakukan perendaman selama 24 jam, menyaring, dan residunya dibilas dengan aquadest hingga pH netral kemudian dioven pada suhu 150°C selama 3 jam. Hasil Karbon aktif dilakukan uji kualitas sesuai dengan SNI 06-3730-1995. Hasil penelitian dalam pembuatan karbon aktif dari serbuk kayu sengon menunjukkan H3PO4 merupakan aktivator terbaik pada ukuran partikel -80,+100 mesh, menghasilkan kadar air, kadar abu, dan daya serap iodin berturut-turut sebesar 3,69%, 2,89%, dan 710,64 mg/g. Uji BET dilakukan pada ukuran partikel -60,+80 mesh sebesar 0,534 m 2 /gram.
AbstractThis study aims to determine the effect of activator types and particle sizes on the characteristics of activated carbon from sengon wood sawdust (Paraserianthes falcataria). The characteristics of activated carbon need to be tested to determine the quality of adsorbent, the test includes testing of water content, ash content, the absorption capacity of iodine, and BET (Braunanear, Emmelt, and Teller). Sengon wood powder which has been mashed then sifted using variations of -20, + 40, -40, + 60, -60, + 80, -80, + 100 mesh. temperature of 500°C for 30 minutes. The activated carbon is activated using activators of H3PO4, NaOH, and NaCl with a concentration of 0.1 M in 100 ml, respectively. The activation process was soaked for 24 hours, filtered and the residue rinsed with distilled water until the pH was neutral, then oven at 150°C for 3 hours. Active carbon results are tested for quality in accordance with SNI 06-3730-1995. The results of the research in the manufacture of activated carbon from sengon wood powder showed that H3PO4 was the best activator in particle size of -80,+100 mesh, resulting in moisture content, ash content, and iodine absorption of 3.69%, 2.89%, 710.64 mg/g respectively, and . The BET test is carried out at a particle size of -60,+80 mesh of 0.534 m 2 / gram.
