<p>Penelitian ini bertujuan untuk mengkaji penggunaan tepung sagu sebagai perakat briket dan mengkaji kualitas briket tempurung pala yang meliputi, kadar air, kadar abu dan laju pembakaran. Penelitian ini dilaksanakan selama dua bulan di dua tempat yaitu, Laboratorium Teknik Pertanian dan Biosistem, Laboratorium Teknologi Pangan dan Gizi Fakultas Pertanian Universitas Sam Ratulangi Manado. Penelitian ini menggunakan metode eksperimental untuk mengetahui pengaruh bahan perekat (tepung sagu) terhadap karakteristik briket tempurung pala dengan perlakuan jumlah perekat tepung sagu (A = 30 g, B = 35 g, dan C = 40 g). Nilai kadar air briket dari tiga perlakuan berbeda (30 g, 35 g dan 40 g) menghasilkan nilai rata-rata 5,58%, 5,89%, dan 6,58%. Kadar abu menghasilkan nilai rata-rata 4,92%, 5,37%, 5,84%. Dari hasil pengamatan laju pembakaran perekat 30 g memiliki laju pembakaran paling rendah (2,88 g/min), perekat 40 g memiliki laju pembakaran tertinggi (3,85 g/min), kemudian perekat 35 g (3,01 g/min). Berdasarkan hasil penelitian briket tempurung pala yang menggunakan tepung sagu sebagai perekat dan bambu sebagai cetakan, menghasilkan 10 buah briket untuk setiap perlakuan. Nilai kadar air dan nilai kadar abu telah memenuhi Standar Nasional Indonesia (SNI). Jumlah perekat tepung sagu mempengaruhi laju pembakaran briket.</p> <p>This study conducted an experiment to evaluate the use of sago starch as a briquette agent and assess the quality of nutmeg shell briquettes. The research was conducted over two months at the Agriculture Engineering and Biosystems Laboratory and Food Technology and Nutrition Laboratory of Sam Ratulangi University in Manado. The study aimed to determine the effect of different amounts of sago starch adhesive (30 g, 35 g, and 40 g) on the characteristics of the briquettes. The moisture content and ash content were measured, and the burning rate was observed. The results showed that the moisture content increased with the amount of adhesive, with average values of 5.58%, 5.89%, and 6.58% for the respective adhesive amounts. The ash content also increased with the adhesive amount, with average values of 4.92%, 5.37%, and 5.84%. The burning rate was found to be the lowest for the briquettes with 30 g adhesive (2.88 g/min) and the highest for those with 40 g adhesive (3.85 g/min), with the 35 g adhesive falling in between (3.01 g/min). Overall, the research indicated that the amount of sago starch adhesive affected the burning rate of the nutmeg shell briquettes.</p> <p>Kata Kunci: Briket arang; Perekat sagu; Tempurung pala</p>
