Pengujian Laminasi Pemanfaatan Sagu/Uyung Sagu sebagai Balok Pengujian Kuat Lentur dengan Variasi Tekanan Kempa 0,4 Mpa 0,6 Mpa Dan 0,8 Mpa dengan Menggunakan Lem Efloor

Increased sago production generates waste with negative environmental impacts.To address this problem, sago waste processing is conducted to create value and reduce environmental pollution.This research examines the physical and mechanical properties of laminated sago bark as test beam material for flexural load resistance, using Efloor adhesive and varied pressing pressures.The laboratory experimental method involved creating laminated beam specimens at three pressing pressure variations: 0.4 MPa, 0.6 MPa, and 0.8 MPa. Flexural strength testing used single-point loading to determine pressing pressure effects on beam strength. Results showed sago bark physical properties: 11.99% moisture content, 0.40-0.60 density, and 0.45-0.50 specific gravity. Mechanical properties included: parallel to-grain compression strength 7-9 MPa, parallel-to-grain shear strength 2-2.5 MPa, parallel-to-grain tensile strength 10-12 MPa, and flexural strength 29-43 MPa. Testing at 0.4 MPa pressing pressure yielded Modulus of Rupture (MoR) of 41.1 and Modulus of Elasticity (MoE) of 8,962.69 MPa.
