KUALITAS BRIKET ARANG DARI CAMPURAN ARANG KAYU KARET (Hevea brasiliensis Muell. Arg) DAN ARANG KAYU ALABAN (Vitex pubescens Vahl)

This research aims to determine the characteristics of charcoal briquettes made from a mixture of rubber wood charcoal and alaban wood charcoal including water content, density, ash content, volatile matter content, bound carbon, heating value in various compositions of the mixture of materials and particle sizes as well as knowing the composition of the materials and The particle size that can produce charcoal briquettes meets SNI 01-6235-2000 standards. The test results show that all treatments can meet SNI standards except only for the rubber wood briquette volatile matter parameter where the composition of 100% 40 mesh rubber wood charcoal powder meets the standard while the composition of 100% 60 mesh rubber wood charcoal powder does not meet the standard. The research results showed that the briquettes consisted of A1B1 treatment (100% 40 mesh rubber wood charcoal powder); treatment A1B2 (100% rubber wood charcoal powder 60 mesh); treatment A2B1 (100% alaban wood charcoal powder 40 mesh); treatment A2B2 (100% alaban wood charcoal powder 60 mesh); treatment A3B1 (50% rubber wood charcoal powder 40 mesh + 50% alaban wood charcoal powder 40 mesh); treatment A3B2 (50% rubber wood charcoal powder 60 mesh + 50% alaban wood charcoal powder 60 mesh), for density values (0.59 g/cm3; 0.57 g/cm3; 0.62 g/cm3; 0.59 g/cm3; 0.57 g/cm3; 0.56 g/cm3), air content (4.53%; 3.95%; 2.57%; 2.86%; 2.66%; 2.99%), ash content (2.44%; 2.97%; 1.15%; 1.10%; 2.10%; 1.57%), volatile matter (14.73%; 15, 81%; 15.80%; 9.26%; 86.78%; 84.10% %; 86.10%) and calorific value (6029.13 cal/g; 5996.33 cal/g; 6457.37 cal/g; 6423.17 cal/g; 6163.31 cal/g; 6233.65 cal/g). Tujuan dari penelitian ini adalah untuk mengetahui karakteristik briket arang yang terbuat dari campuran arang kayu karet dan arang kayu alaban meliputi kadar air, kerapatan, kadar abu, kadar zat terbang, karbon terikat, nilai kalor pada berbagai komposisi campuran bahan dan ukuran partikel serta mengetahui komposisi bahan dan ukuran partikel yang dapat menghasilkan briket arang memenuhi standar SNI 01-6235-2000. Hasil pengujian menunjukkan semua perlakuan dapat memenuhi standar SNI kecuali hanya pada parameter zat terbang briket kayu karet dimana komposisi 100% serbuk arang kayu karet 40 mesh memenuhi standar sedangkan komposisi 100% serbuk arang kayu karet 60 mesh tidak memenuhi standar. Hasil penelitian menunjukkan briket yang terdiri dari perlakuan A1B1 (100% serbuk arang kayu karet 40 mesh); perlakuan A1B2 (100% serbuk arang kayu karet 60 mesh); perlakuan A2B1 (100% serbuk arang kayu alaban 40 mesh); perlakuan A2B2 (100% serbuk arang kayu alaban 60 mesh); perlakuan A3B1 (50% serbuk arang kayu karet 40 mesh + 50% serbuk arang kayu alaban 40 mesh); perlakuan A3B2 (50% serbuk arang kayu karet 60 mesh + 50% serbuk arang kayu alaban 60 mesh), untuk nilai kerapatan (0,59 g/cm3; 0,57 g/cm3; 0,62 g/cm3; 0,59 g/cm3; 0,57 g/cm3; 0,56 g/cm3), kadar air (4,53%; 3,95%; 2,57%; 2,86%; 2,66%; 2,99%), kadar abu (2,44%; 2,97%; 1,15%; 1,10%; 2,10%; 1,57%), zat terbang (14,73%; 15,81%; 15,80%; 9,26%; 11,15%; 9,34%), karbon terikat (78,30%; 77,27%; 80,48%; 86,78%; 84,10%; 86,10%) serta nilai kalor (6029,13 kal/g; 5996,33 kal/g; 6457,37 kal/g; 6423,17 kal/g; 6163,31 kal/g; 6233,65 kal/g).
