Abstract

This study will try to investigate variations in the angle of the Z-direction build part by using a 3D Printer with Fused Deposition Modeling (FDM) technology made from PLA + Sugoi. This study uses a 0.4mm nozzle with a Bowden type extruder. This study uses a PLA+ filament from the Sugoi brand with a nozzle of 0.4 mm, diameter filament 1,75 mm, 3D Printer with Fused Deposition Modeling (FDM) technology used is Creality Ender 3 V2 with process parameter settings in slicing software using a layer thickness of 0.30 mm, Top solid Layer 5, Bottom Solid Layer 5, Fill density 100%, cooling speed 100%, and flowrate 100%, nozzle temperature 205°C, and bed temperature 60°C. Variation in angle Part build Z-direction is proven to have a significant difference in Tensile strength with a difference of 10° resulting in a difference in Tensile strength of 15 MPa, where the highest tensile strength is 67.50 MPa with part build Z-direction at an angle of 80°, and the lowest tensile strength of 52.50 MPa with a Z-direction part build angle at an angle of 70°.

Abstract

Bengkel Pelabuhan Perikanan Nusantara (PPN) Sungailiat menyediakan layanan perbaikan alat produksi nelayan. Kurangnya pemeliharaan terhadap mesin-mesin yang ada menyebabkan seringnya terjadi kerusakan mesin yang berakibat pada terganggunya layanan tersebut. Kegiatan pengabdian ini bertujuan untuk merancang dan mengimplementasikan program pemeliharaan preventif di Bengkel PPN dengan melibatkan operator mesin melalui pendekatan pemeliharaan rutin dan berkala. Metode yang digunakan mencakup identifikasi mesin kritis, perencanaan, penjadwalan, dan pelatihan personel. Program pemeliharaan ini diterapkan pada mesin bubut dan mesin frais. Rancangan program pemeliharaan yang dihasilkan berupa kartu pemeliharaan preventif (PM check list) harian dan inspeksi berkala 6 bulanan, jadwal pemeliharaan preventif tahunan, serta pelatihan bagi personil bengkel. Hasil implementasi menunjukkan bahwa program pemeliharaan preventif ini dapat dilaksanakan dengan efektif oleh personil bengkel

Abstract

Fishing has transformed from a traditional livelihood into an increasingly popular hobby among people, involving various age groups and locations. Fishing rods, as the main tool in the fishing process, function to catch fish by reducing the load and providing lifting power. This study aims to explore the use of resam fiber as an alternative material in making fishing rods, considering the limitations and high costs of graphite rods. The rod manufacturing process uses the Hand lay-up technique, where the resam fiber undergoes alkalization with 5% NaOH for 1, 2, and 3 hours, and variations in the number of fibers of 5, 10, and 15 strands. The results showed that specimens with 15 strands of fiber soaked for 2 hours produced the highest average tensile value of 44.6 MPa and the highest bending value of 57.6 MPa. This study shows the potential of resam fiber as a strong and affordable material for making fishing rods, providing a better alternative to graphite rods available on the market.

Abstract

This research aims to obtain the appropriate composition in the production of alternative materials for fishing rods with fiber-resin reinforcement, as well as to determine the tensile and bending test results for the alternative material to be used as fishing rods. This study uses a full factorial method to determine the number of spesimens to be made, with variations in fiber-resin composition: the number of fibers used is 5, 10, and 15 strands, with a resin-to-catalyst ratio of 50:1 and drying times of 1 hour, 2 hours, and 3 hours. Tensile strength tests were performed on 9 spesimens with 3 replications, and bending tests were conducted on 9 spesimens with 3 replications per spesimen, resulting in a total of 54 spesimens tested. Based on the best tensile test results, the spesimen with 15 strands of fiber soaked for 2 hours in a 5% NaOH solution achieved a tensile strength of 46.2 MPa, while the lowest tensile strength was obtained from the spesimen with 5 strands of fiber soaked for 2 hours, which was 19.9 MPa. The average tensile test results showed a maximum value of 38.4 MPa
