Abstract

Serabut kelapa muda dan tempurung kelapa merupakan limbah pada pengolahan kelapa. Di muara Teweh pada Kabupaten Barito Utara banyak ditemukan limbah tempurung pada usaha kelapa parut dan serabut kelapa muda pada usaha es kelapa muda. Keberadaaan limbah ini memerlukan pengelolaan agar dapat digunakan dan dimanfaatkan lebih lanjut. Pemanfaatan kedua limbah tersebut dapat dilakukan dengan mengolah limbah menjadi asap cair. Asap cair memiliki manfaat karena kandungan senyawa organik yang terkandung di dalamnya. Tujuan penelitian ini adalah untuk mengetahui kandungan senyawa organik asap cair dari limbah serabut muda dan tempurung kelapa yang terdapat di Muara Teweh. Penelitian ini dilakukan di Laboratorium Biokimia dan Rekayasa Politeknik Muara Teweh. Penelitian dilakukan melalui 2 (dua) tahapan yaitu : pengolahan asap cair menggunakan pirolisator mini dan penetapan kandungan asap cair dengan menggunakan GCMS. Hasil penelitian menunjukan rendemen asap cair untuk serabut kelapa sebesar 15% dan tempurung kelapa 16%. Hasil pengukuran pH diketahui bahwa pH asap cair serabut kelapa muda 4,01 dan pH asap cair tempurung kelapa 3,35 adapun warna dari kedua asap cair tersebut adalah hitam pekat. Kandungan senyawa organik tertinggi pada asap cair dari serabut kelapa muda adalah dedecanoic acid, 1,2,3-propanetriyl ester sebanyak 33.058%, dan asap cair dari tempurung kelapa adalah dedocanoic acid, 1,2,3-propanetriyl ester sebanyak 25.154%.

Abstract

Oil palm empty fruit bunches (OPEFB) can be processed into liquid smoke through pyrolysis. This study aimed to obtain the best concentration of unpurified liquid smoke from OPEFB in inhibiting the growth of the fungus of Ganoderma boninense. OPEFB samples were obtained from PT. Citra Putra Kebun Asri and G. boninense were collected from Muara Teweh Plantation. The study was conducted in 2 stages; Analysis of liquid smoke from pyrolysis using the GC-MS method at the Organic Chemistry Laboratory, Faculty of Mathematics and Natural Sciences, Gadjah Mada University; and testing the inhibition of liquid smoke on G. boninense in vitro at the Basic Plantation Cultivation Laboratory, Hasnur Polytechnic, and the Microbiology Laboratory of Plantation Products Processing Technology, Muara Teweh Polytechnic. This study was conducted in a completely randomized design with four treatments and six replications. The treatment was the difference in concentration of liquid smoke (1 ml/AC1, 2 ml/AC2, 3 ml/AC3, and control/AC0) in the planting medium, potato dextrose agar (PDA). The results showed that the average yield of unpurified liquid smoke from OPEFB was 34.5%, containing 49.28% acetic acid, 11.57% methyl alcohol, and 9.10% phenol. Application ? 2 ml liquid smoke in PDA completely inhibited G.boninense's growth in vitro, starting three days after application.
