Abstract

Natural reisourceis such as wind can bei an alteirnativei for poweir geineiration through thei usei of wind turbineis. Onei impleimeintation is thei deiveilopmeint of reineiwablei eineirgy in poteintial locations, such as Turun Aban Beiach in Matras Villagei, Bangka, Bangka Beilitung Islands. This beiach is oftein useid as an anchoragei for fishing boats, but doeis not yeit havei an eileictric poweir supply. To meieit theiir neieids, fisheirmein can utilizei wind turbineis as an alteirnativei poweir geineiration option. Thei teist reisults show that at an aveiragei wind speieid of 1.97 m/s, thei wind turbinei produceis 3.96 watts of poweir

Abstract

The 3D printer filament extruder is a machine used to melt and extrude filament for 3D printing processes. Thermoplastics are one type of plastic commonly used in filament production due to their durability, strength, and easy to shape, making them a preferred material for filament manufacturing. Filament is produced through an extrusion process using a machine equipped with a high-temperature heating system to shape the filament. The aim of this research is to design, construct, and test a 3D printing filament extruder to produce filament. This research produces a 3d printing filament extruder machine with a vertical position that uses a DC motor as a driving mechanism, while chains and sprockets are used to reduce rotation and increase rotational torque. Based on the results of the trials conducted, the barrel temperature of 250°C and the screw rotation speed of 5 RPM which produces a filament diameter that is close to the standard for filament use with an average filament diameter of 1.97 mm.

Abstract

The use of oil palm fronds is rarely used in the world of research. Oil palm fronds are only used in animal feed such as goats and cows, but in this study, oil palm fronds are used to make composite materials. Composites are a combination of reinforcement and binder. The reinforcement uses oil palm frond fiber while the binder uses resin. In this tensile test to determine the effect of the volume fraction of oil palm frond fiber with a volume fraction of 35%, 40%, and 45% while soaking in 5% NaOH for 2 hours. The results showed a tensile strength of 35% of 30.7 MPa, 40% of 38.8 MPa and 45% of 42.5 MPa. So the highest tensile strength is in the volume fraction of 45% and the lowest tensile strength is in the volume fraction of 35%.

Abstract

The safety aspect is important that must be considered in vehicles, because components that not comply with standards can pose serious risks. The use of asbestos also have a negative impact on health, caused by exposure to contaminated air and can damage respiratory system. This research aims to develop environmentally friendly brake linings, as well as studying the effect of two-way hot compaction pressure and reinforcement volume percentage on friction coefficient. This research uses powder metallurgy method which starts from the process mixing recycled aluminium powder, silica sand, and palm oil boiler fly ash, using ball mill machine (BPR 10:1) at speed 90 rpm, for 6 hours. Compaction was carried out in two directions with pressure variants of 5000, 5400 and 5800 Psi at temperature 350°C for 10 minutes. The sintering process was carried at temperature 600°C with holding time of 10 minutes. Friction coefficient testing is carried out to calculate the wear by following the ASTM G99-05 standard. The results show that increasing the percentage reinforcement and compaction pressure can increase friction resistance, highest wear value of 0.055 gr with parameters (84% reinforcement, pressure 5000 Psi) and the lowest wear value of 0.032 parameters (92% reinforcement, pressure 5800 Psi).
