Physical Properties of Varied Composition of Peanut Shell and Palm Oil Shell’s Briquettes

Abstract

This research aims to determine the physical properties of briquettes made from peanut shell (KKT) and palm oil shell (CKS) waste. The manufacturing process is carried out using a briquette press with a pressure of 70 N/m2, and each KKT and CKS is measured at 100 mesh. Two grams of starch adhesive and 15 ml of water are used in the process. This research method involves varying the quantities of KKT and CKS with the following ratios: S1(18:0), S2(16:2), S3(14:4), S4(12:6), S5(10:8), S6(8:10), S7(6:12), S8(4:14), S9(2:16), S10(0:18). The results of this research show that the lowest density of briquettes, 708.38 kg/m3, was produced by sample S6, while the highest density, 876.91 kg/m3, was produced by sample S3. The lowest elastic modulus of briquettes, 7 MPa, was recorded for sample S6, and the highest elastic modulus, 60 MPa, was observed for sample S10. Similarly, the lowest ultimate strength of briquettes, 1.35 MPa, was found in sample S6, while the highest ultimate strength, 6.03 MPa, was achieved in sample S10.
