Analisis Sifat Fisika dan Kimia terhadap Pembuatan Briket Arang Limbah Biji Salak dengan Variasi Perekat Tepung Tapioka dan Tepung Sagu

Abstract

Telah dilakukan pembuatan briket arang berbahan dasar biji salak dengan variasi perekat tepung tapioka dan tepung sagu. Variasi komposisi biji salak dengan perekat tepung tapioka dan tepung sagu antara lain: sampel A (65% : 30%), B (70% : 30%), dan C (75% : 25%), perbandingan perekat dengan air (1:3), serta waktu pengeringan selama 7 hari. Parameter uji fisika dan kimia meliputi: kadar air, nilai kalor, kadar abu, kadar zat terbang, dan kadar karbon. Hasil uji fisika dan kimia briket arang biji salak diperoleh briket arang yang optimal yaitu pada sampel A dengan perekat tepung sagu. Pada sampel A, briket arang yang diperoleh menghasilkan nilai kadar air 5,17%, nilai kalor 5377,85 Cal/g, kadar abu 5,21%, kadar zat terbang 9,62%, dan kadar karbon 78,53%. Sampel briket arang telah sesuai dengan SNI No.01-6235-2000, dan briket arang dapat digunakan dalam skala rumah tangga. Kata kunci: Briket arang biji salak Sifat kimia Tepung tapioka Tepung sagu Keywords: Salak seed charcoal briquettes Chemical properties Tapioca flour Sago flour Charcoal briquettes made from zalacca seeds with various adhesives from tapioca flour and sago flour have been carried out. Variations in the composition of salak seeds with tapioca starch and sago flour adhesive include samples A (65%: 30%), B (70%: 30%), and C (75%: 25%), the ratio of adhesive to water (1:3), as well as drying time for 7 days. The physical test parameters are water content and calorific value. Chemical test parameters include ash content, volatile matter content, and carbon content. The results of the physical and chemical tests of zalacca seed charcoal briquettes obtained the optimal charcoal briquettes in sample A with sago flour adhesive. In sample A, the charcoal briquettes obtained yielded a moisture content of 5.17%, a calorific value of 5377.85 Cal/g, an ash content of 5.21%, a volatile matter content of 9.62%, and a carbon content of 78.53%. Charcoal briquette samples comply with SNI No.01-6235-2000, and charcoal briquettes can be used on a household scale.
