N2  - Meningkatnya populasi manusia dan perindustrian mengakibatkan
kebutuhan energi yang tinggi, dimana selama ini dipenuhi oleh bakar fosil. Bahan
bakar tersebut bersifat terbatas, tidak dapat didaur ulang dan memiliki dampak
negatif bagi lingkungan, sehingga diperlukan alternatif pengganti bahan bakar
fosil berupa biobriket. Tujuan dilakukannya penelitian ini adalah untuk
menghasilkan produk bahan bakar berupa biobriket dari limbah pertanian yang
ramah lingkungan, mengkaji dan mempelajari kandungan energi dan karakteristik
biobriket serta nganalisis kelayakan ekonomi biobriket yang dihasilkan. Penelitian
ini disusun secara faktorial dalam Rancangan Acak Lengkap (RAL) dengan dua
faktor dan tiga ulangan. faktor pertama (P) ialah perbandingan komposisi bahan
antara limbah batang singkong, limbah tempurung kelapa dan limbah batang
bambu yang terdiri dari tiga taraf perlakuan yaitu perbandingan komposisi limbah
batang singkong, tempurung kelapa dan batang bambu sebesar 60:20:20 (P1),
perbandingan komposisi limbah batang singkong, tempurung kelapa dan batang
bambu sebesar 20:60:20 (P2), perbandingan komposisi limbah batang singkong
tempurung kelapa dan batang bambu sebesar 20:20:60 (P3) dan perbandingan
komposisi limbah batang singkong, limbah tempurung kelapa dan batang bambu
sebesar 30:35:35 (P4). Faktor kedua adalah faktor perekat tapioka (T) dengan
konsentrasi perekat tapioka sebesar 5% (T1) dan konsentrasi perekat campuran
tapioka dan clay sebesar 5% (T2). Parameter yang diamati terdiri dari kerapatan,
kadar air, kekuatan tekan, shatter resistance index, nilai kalor, laju pembakaran,
dan suhu pembakaran bioriket. Kelayakan ekonomi biobriket ditentukan
berdasarkan besarnya nilai Revenue Cost Ratio (R/C Ratio) dan Pay Back Period
(PBP). Karakteristik biobriket yang dihasilkan pada kerapatan berkisar 0,5-0,71
g/cm3, kadar air berkisar 7,15-8,52%, kekuatan tekan briket berkisar 98,28%, nilai
kalor berkisar 5738-6513 kal/g, laju pembakaran berkisar 1,085-2,38 g/menit, dan
pembakaran rata-rata yang diperoleh adalah berkisar 118-288oC. Biobriket yangtelah dibuat, pada seluruh perlakuan dinyatakan layak secara ekonomi karena
memiliki nilai R/C Ratio berkisar antara 1,4-1,6. Nilai payback period yang
diperoleh berkisar antara 1,4-2,5 tahun.

The increase in human population and industry has resulted in a high
demand for energy, which has so far been met by fossil fuels. This fuel is limited,
cannot be recycled and has a negative impact on the environment, so an
alternative to fossil fuels is needed in the form of biobriquettes. The purpose of
this research is to produce fuel products in the form of biobriquettes from
environmentally friendly agricultural waste, to study and study the energy content
and characteristics of biobriquettes and to analyze the economic feasibility of the
resulting biobriquettes. This study was arranged factorially in a completely
randomized design (CRD) with two factors and three replications. The first factor
(P) is the comparison of the material composition between cassava stem waste,
coconut shell waste and bamboo stem waste which consists of three treatment
levels, namely the ratio of the composition of waste cassava stems, coconut shell
waste and bamboo stems of 60:20:20 (P1), the ratio composition of waste cassava
stems, coconut shells and bamboo stems was 20:60:20 (P2), the ratio of the
composition of waste coconut shell cassava stems and bamboo stems was
20:20:60 (P3) and the composition ratio of waste cassava stems, coconut shell
waste and bamboo sticks of 30:35:35 (P4). The second factor was the tapioca
adhesive factor (T) with a tapioca adhesive concentration of 5% (T1) and a
mixture of tapioca and clay adhesive concentration of 5% (T2). Parameters
observed consisted of density, moisture content, compressive strength, shatter
resistance index, calorific value, burning rate, and bottom temperature of the pan
when burning briquettes. The economic feasibility of biobriquettes is determined
based on the value of the Revenue Cost Ratio (R/C Ratio) and the Pay Back
Period (PBP). The characteristics of the biobriquettes produced at densities
ranged from 0.5-0.71 g/cm3, moisture content ranged from 7.15-8.52%,
compressive strength of the briquettes ranged from 98.28%, calorific value
ranged from 5738-6513 cal/g, rate combustion ranges from 1.085-2.38 g/minute,
and the average combustion obtained is around 118-288oC. The biobriquettes that
have been made, in all treatments were declared economically viable because
they had R/C ratio values ranging from 1.4 to 1.6. The payback period values
obtained ranged from 1.4-2.5 years.
