Abstrak Tahapan pengolahan karet alam konvensional secara umum masih panjang dan memerlukan waktu yang lama. Proses pengeringan menjadi tahapan utama dalam proses pengolahan karet alam. Teknologi pengeringan semprot dapat menjadi solusi untuk mengurangi proses pengolahan karet alam yang panjang. Penentuan dan perancangan ruang pengering serta kondisi operasi pengeringan semprot dapat dilakukan menggunakan simulasi komputasi. Penelitian ini bertujuan untuk mengevaluasi dan mengkaji kondisi operasi dari proses pengeringan lateks karet alam menggunakan teknik pengeringan semprot melalui simulasi komputasi. Variabel perlakuan yang diberikan berupa laju alir umpan lateks (0,2; 0,4; 0,6; dan 0,8 kg/jam), kadar air umpan (70%, 75%, 80% dan 85%) dan suhu udara pengering (140 °C, 160 °C, 180 °C dan 200 °C). Hasil penelitian menunjukkan bahwa variabel perlakuan yang diberikan memberikan pengaruh terhadap ukuran diameter droplet, laju pengeringan, serta bobot massa, kadar air, dan temperatur produk akhir. Berdasarkan hasil simulasi komputasi diperoleh bahwa kondisi operasi terbaik yang dapat dipilih untuk proses pengeringan semprot lateks karet alam yaitu laju alir umpan maksimum 0,4 kg/jam dengan temperatur udara pengering sekitar 180 °C. Kondisi operasi ini bisa diterapkan untuk ruang (chamber) pengering dengan dimensi bagian silinder berdiameter 35 cm dan ketinggian 63 cm serta ketinggian bagian kerucut sekitar 40 cm.References
