“…From water content values, it can be seen that the higher composition of the biomass (rubber seed shell) used would reduce the water content. While higher coal bottom ash composition would increase the water content, this is in line with research conducted by Gunawan and Slamet [10]. In this study, the water content was ranged from 4.35% -10.56%.…”

Research has been carried out on the use of coal bottom ash as a material for making briquettes as an alternative fuel. Carbonized of rubber seed shells and Halaban wood were used as mixtures and tapioca flour as adhesives. The composition used in making Halaban wood charcoal and coal bottom ash briquettes is 100%: 0%, 90%: 10%, 80%: 20% and 70%: 30%. Tapioca flour used was as much as 5%, the pressure of 150 kg/cm2 and the size of 250 meshes. While for rubber seed shell and coal bottom ash briquettes, the composition used was with ratio 60%: 40% and 70%: 30%; the pressure used was 100, 150 and 200 kg/cm2 and the size of 50 meshes. Tapioca flour used was as much as 5%. The results of the characterization of rubber seed shell and coal bottom ash briquettes were water content (4.35 - 10.65)%, ash content (12.53 - 17.26)%, and calorific value (3,597.59 - 4,549.88) cal/g. While the characterization results of Halaban wood charcoal and coal bottom ash briquettes were water content (2.947 – 4.097)%, ash content (0.383 – 26.667)%, and calorific value (4,749-6,621) cal/g. The results showed that if coal bottom ash in the composition were higher, it would increase the water content and ash content of the briquettes, while the calorific value would be lower. The recommended composition of coal bottom ash was about 10-20 %. While if the briquettes pressure was higher, the water content, ash content and calorific value would be smaller. The recommended pressure was 150 kg /cm2.

“…Briket memiliki emisi karbon monoksida (CO) yang rendah dibandingkan bahan bakar lain seperti minyak tanah, dan menjadikan briket sumber energi yang lebih aman bagi kesehatan. Hasil uji Badan Pengkajian dan Penerapan Teknologi (BPPT) yang menyatakan bahwa pembakaran 1 kg briket selama 2 -3 jam akan menghasilkan emisi karbon monoksida (CO) rata-rata 106 ppm, sementara menurut Gunawan (2015), minyak tanah 250 -390 ppm atau tiga kali lipatnya. Bahan baku yang bisa di gunakan untuk pembuatan briket adalah limbah serbuk gergaji kayu bayur.…”

Abstract. Kayu bayur banyak digunakan untuk pembuatan bahan baku furnitur yang menghasilkan limbah serbuk gergaji. Kayu bayur memiliki nilai kalor sebesar 4.452,01 kal/gr, kadar abu 1,04% dan kadar air 19,29%. Serbuk gergaji kayu bayur ini sangat berpotensi digunakan sebagai bahan pembuatan briket dengan penambahan perekat. Bahan yang bisa digunakan sebagai pengganti perekat tepung tapioka adalah daun tanaman biduri. Tanaman biduri memiliki kandungan kimia seperti selulosa, pentosan sebagai hemiselulosa, lignin, abu, tanin 9,1mg/g dan pektin 55%. Pembuatan briket dengan perekat daun biduri bertujuan untuk mengetahui bagaimana pengaruh berbagai variasi perekat, dan bagaimana karakteristik briket yang dihasilkan. Penelitian yang telah dilakukan mendapatkan hasil bahwa dari variasi kadar perekat 35%, 40%, dan 45% pada briket terbaik yaitu pada variasi ke BB3 diaman 55% (30 g) arang serbuk gergaji kayu bayur dengan 45% (24,5 g) perekat daun biduri dan karakteristiknya mencapai nilai SNI briket No.1/6235/2000. Pada perlakuan ini nilai yang diperoleh yaitu untuk kadar air 1,8%, kadar abu 7,42%, densitas 0,4235 g/cm3, nilai kalor 5.069,589 kal/g, dan uji tekan 4,0538 kg/cm2.The Use of Leaves Biduri (Calotropis Gigantea) as Adhesives to Making Briquettes Sawdust Wood Bayur (Pterospermum Javanicum)Abstract. Bayur wood is widely used for manufacturing furniture raw materials that produce sawdust waste. Bayur wood has a calorific value of 4,452.01 cal/g, ash content of 1.04% and a moisture content of 19.29%. This bayur wood sawdust is very potential to be used as a briquette making material by adding adhesive to the briquetting process. Material that can be used as a substitute for tapioca flour adhesive is the leaves of the biduri plant. Betell plants have chemical properties like cellulose, pentatosan as hemicellulose, lignin, as, tannin 9.1 mg/g and pectin 55%. The making of briquettes with biduri leaf adhesive aims to find out how the influence of various variation of the adhesive, and how the characteristics of the briquettes produced. The research that has been carried out shows that the variation of 35%, 40%, and 45% adhesive content in the best briquettes is in the variation to BB3 where 55% (30 g) chacrcoal of sawdust with 45% (24.5 g) of adhesive biduri leaves and their characteristics reach to SNI briquettes No.1/6235/2000. In this treatment the values obtained are for water content of 1.8%, ash content of 7.42%, density 0.4235 g/cm3, calorific value of 5,069.589 cal/g, and pressure test of 4.0538 kg/cm2.

Moisture content, ash content and heating value have been measured on briquettes which were made from a mixture of halaban charcoal and coal bottom ash with variations in pressures and form factor. Factors that influence the characteristics of briquettes were powder fineness and pressure. And so both materials were made in the form of powder on a 250 mesh sieve and pressure variations (150, 200, 250, 300, and 350) kg / cm2. The composition of the mixture of halaban charcoal and coal bottom ash was with a ratio of 90%: 10%, while 5% of starch adhesive was added. Briquettes were made in the form of solid cylinders and hollow cylinders. From the measurements, the moisture content, ash content and heating value of solid cylinder briquettes were yielded 3.831-5.892%, 7.178-10.507% and 5,607.467-5,732.033 cal/g, respectively. While for hollow cylinder briquettes were 4.564-5.621%, 8.688-11.191% and 5,620.833-5,685.100 cal/g. All briquette samples meet Indonesian national standards requirements for moisture content and heating value, but not all briquette samples meet the requirements for ash content. Higher pressure gave lower water and ash content, but higher heating value. Based on the results, it is recommended that the pressure given in making the briquette was 200 kg/cm2. This is based on consideration of the highest heating value obtained when the pressure was 200 kg / cm2.
