Abstract

Natural fibers have been considered as reinforcement in composite materials which is environmentally friendly fiber instead of fiberglass. The use of natural fibers in the composite material is currently growing, along with the increasing use of such materials are widespread ranging from household appliances and industrial sector. The aim of this research was to determine the impact strength and bending strength of lontar fiber composite. The production method of this composite is hand lay-up with random fiber orientation (randomly oriented fiber discontinuous). The composites were produced with a variety of fiber volume fraction of 10%, 15%, 20%, 25% and 30 %. The bending strength of lontar fiber composite 140.235 MPa and modulus of elasticity of 4440 Mpa were obtained. The impact strength of lontar fiber composite and fiberglass were 0.439J/mm2 and 0.8333 J / mm2 respectively.

Abstract

Penelitian ini bertujuan untuk mengetahui respons nilai kekerasan pahat bubut hardfacing hasil modifikasi mata potong terhadap kekasaran permukaan, sehingga dapat menghasilkan pahat bubut alternatif untuk mengatasi keterbatasan pengadaan alat potong di laboratorium demi meningkatkan kompetensi mahasiswa dan kualitas layanan bagi pengguna laboratorium. Metode yang digunakan meliputi tahap perancangan, persiapan, pembuatan, serta demonstrasi pada mesin bubut. Parameter pemesinan yang divariasikan meliputi kedalaman potong 0,1 mm, 0,2 mm, dan 0,3 mm; putaran mesin 320 rpm, 440 rpm, dan 540 rpm; dengan material kerja aluminium, baja St 37, dan baja S45C. Hasil pengujian menunjukkan bahwa nilai kekerasan maksimum pahat hardfacing adalah 65,16 HRC dengan nilai kekasaran permukaan 2,953 μm pada material baja St 37. Sementara itu, nilai kekerasan minimum sebesar 62,06 HRC menghasilkan kekasaran permukaan 3,521 μm pada material S45C. Untuk proses pemesinan, nilai kekasaran maksimum (paling kasar) tercatat 5,108 μm pada material baja St 37, sedangkan nilai kekasaran minimum (paling halus) sebesar 0,939 μm diperoleh pada material aluminium
