Pemanfaatan biomassa sebagai biopelet merupakan salah satu cara pemenuhan kebutuhan energi. Pemanfaatan limbah biomassa daun bawang merah campuran serbuk kayu sengon dapat diolah menjadi biopelet, sehingga perlu kajian tentang karakteristik biopelet campuran limbah daun bawang merah dan serbuk kayu sengon. Tujuan penelitian ini adalah: 1) Mengetahui karakteristik biopelet daun bawang merah dan serbuk kayu sengon. 2) Mengetahui pengaruh ukuran terhadap kualitas biopelet daun bawang merah dan serbuk kayu sengon. 3) Menentukan komposisi formulasi terbaik pada pembuatan biopelet daun bawang merah dan serbuk kayu sengon. 4) Menguji dan menganalisis kualitas biopelet yang mengacu pada SNI 8021:2014. Penelitian ini menggunakan model rancangan acak lengkap faktorial dengan 2 (dua) faktor yaitu variasi ukuran mesh 20 mesh, 40 mesh, 60 mesh dan variasi komposisi dengan perbandingan daun bawang merah dan serbuk kayu sengon, 100%:0%, 75%:25%, 50%:50% dengan tiga kali ulangan. Pengujian biopelet yang dilakukan meliputi:  kadar air, kadar abu, kadar zat terbang, kerapatan dan laju pembakaran. Hasil pengujian karakteristik biopelet diperoleh nilai rata-rata kadar air berkisar 7,67%bb-13,67%bb, kadar abu 8,33%-15,67%, kadar zat terbang 85,04%-91,57%, nilai kerapatan 0,44 g/cm3 -0,50 g/cm3  dan laju pembakaran 0,111 g/menit-0,168 g/menit. Penelitian ini menunjukkan bahwa semakin halus ukuran serbuk dan komposisi serbuk kayu sengon banyak maka kadar air, kadar abu, dan laju pembakaran akan semakin rendah, namun nilai densitas dan kadar zat terbang meningkat. Biopelet dengan kualitas terbaik diperoleh pada perlakuan A2B3 yaitu perbandingan komposisi daun bawang merah dan serbuk kayu sengon 75%:25% dengan ukuran serbuk 60 mesh, dengan karakteristik kadar air 7,67%bb, kadar abu 12,33%, kadar zat terbang 89,90%, nilai kerapatan 0,50 g/cm3  dan laju pembakaran 0,168 g/menit.

Utilization of biomass as biopellet is one way to meet energy needs. Utilization of biomass waste from shallot leaf mixed with sengon wood sawdust can be processed into biopellets, so it is necessary to study the characteristics of biopellets from a mixture of shallot leaf waste and sengon wood sawdust. The purposes of this study were: 1) To determine the characteristics of the biopellets of shallot leaf and sengon wood sawdust. 2) Knowing the effect of size on the quality of biopellets of shallot leaf and sengon wood sawdust. 3) Determining the best formulation composition for the manufacture of shallot leaf biopellets and sengon wood sawdust. 4) Testing and analyzing the quality of biopellets referring to SNI 8021:2014. This study used a completely randomized design model with 2 (two) factors, namely variations in mesh size of 20 mesh, 40 mesh, 60 mesh and variations in composition with a ratio of biopellets of shallot leaf and sengon wood sawdust 100%: 0%, 75%: 25%, 50%:50% with three replications. Types of tests performed on biopelet include density, moisture content, volatile matter, ash content and combustion rate. The results of testing the characteristics of biopellets obtained an average value of moisture content ranged from 7,67%bb- 13,67%bb, ash content 8,33% - 15.67%, volatile matter 85,04%-91,57%, density value 0,44 g/cm3 -0,50 g/cm3  and combustion rate 0,111 g/minute-0,168 g/minute. The test results show that the finer the size of the particle and the composition of the more sengon wood powder, the lower the moisture content, ash content, and combustion rate, but the density and volatile matter content increased. Biopellets with the best quality were obtained in the A2B3 treatment, namely the comparison of the composition of shallots leaf and sengon wood powder 75%:25% with a particle size of 60 mesh. The results of the characteristics of the biopellets obtained include moisture content of 7,67%bb, ash content of 12,33%, volatile matter of 89,90%, density value of 0,50 g/cm3 and combustion rate of 0,168 g/minute.
