Kualitas Bakar Briket Bioarang Campuran Arang Kotoran Kambing dan Mayang Lontar

Abstract

Experiment aimed to determine the burning quality of biocharcoal briquette mix of goat dung and lontar male fruit charcoal. Completely randomized design with 4 treatments and 4 replicates was applied. Those treatment were P1= goat dung charcoal 25% + lontar male fruit 75%, P2= goat dung charcoal 50% + lontar male fruit 50%, P3= goat dung charcoal 75% + lontar male fruit 25%, P4= goat dung charcoal 100%. Variable observed were burning temperature, burning rate, burning resistance, burning color, smoke and water boiling ability. Results showed that treatment had a very significant effect (P<0.01) on burning color; significant (P<0.05) on burning resistance but no significant (P>0.05) on burning temperature, burning rate, smoke and water boiling ability. Avarage of burning temperature 213.44°C, burning rate 2.88 g/m, burning resistance 136.25 minutes, color score 2.6, smoke score 3.98 and water boiling ability 27.97 minutes. It was concluded that mixing of goat dung and lontar male fruit with increase of goat dung produce the biocharcoal briquettes with decrease of burning quality. The best of burning quality indicated by P2 that is mixed of 50% of both goat dung and lontar male fruit. Penelitian bertujuan mengetahui pengaruh campuran arang kotoran kambing dan mayang lontar terhadap kualitas bakar briket bioarang. Metode yang digunakan adalah Rancangan Acak Lengkap terdiri atas 4 perlakuan dan 4 ulangan. Perlakuan tersebut adalah P1= arang kotoran kambing 25% + mayang lontar 75%, P2= arang kotoran kambing 50% + mayang lontar 50%, P3= arang kotoran kambing 75% + mayang lontar 25%, P4= arang kotoran kambing 100%. Variabel yang diteliti: temperatur bakar, laju pembakaran, ketahanan bakar, warna pembakaran, asap, dan kemampuan mendidihkan air. Hasil sidik ragam menunjukkan perlakuan berpengaruh sangat nyata (P<0,01) terhadap warna pembakaran, berpengaruh nyata (P<0,05) terhadap ketahanan bakar tetapi berpengaruh tidak nyata (P>0,05) terhadap temperatur bakar, laju pembakaran, asap, dan kemampuan mendidihkan air. Rerata temperatur bakar 213,44°C; laju pembakaran 2,88 g/m; ketahanan bakar 136,25 menit; warna pembakaran cenderung merah (skor 2,6); dan tidak ada asap (skor 3,98); kemampuan mendidihkan air 27,97 menit. Disimpulkan bahwa campuran kotoran kambing dan mayang lontar dengan level kotoran kambing yang meningkat menghasilkan briket bioarang dengan kualitas bakar yang menurun. Kualitas bakar terbaik diperlihatkan pada P2 yaitu arang kotoran kambing 50% dan mayang lontar 50%.
