Abstract

Currently, using natural fibers as composite reinforcement is a new pattern in material technology. Natural fiber-reinforced composite materials have sustainable potential in the industrial field because the natural fibers used significantly impact the composite's mechanical properties. However, the chemical content of natural fibers can affect the mechanical properties of the composite. Therefore, chemical treatment of fibers that will be used as composite reinforcement must be done to produce mechanical properties such as optimal impact strength. This research aims to see the effect of treatment time on citronella fibers and the type of treatment solution on the resulting impact strength. The method used in this research is a 2k factorial design. In this study, the impact test used the ISO 179-01 standard reference with the treatment of citronella fiber soaked using liquid smoke solution and fiber boiling using turmeric solution, and the length of the treatment process was 1 hour and 3 hours. The results showed that the interaction between the type of solution and the length of treatment time affected the impact strength.

Abstract

Natural resources in the form of solar heat, can be used as an alternative to electricity generation by using a power plant tool in the form of solar panels. In certain areas there are still many who need a supply of electric power, for example in the Turun Aban Sungailiat Beach area, Bangka Belitung Islands Province. At that location there is no electric power supply at all, the fishermen at the Turun Aban Beach location often carry out the process of transporting catches at night conditions. Therefore, to meet their needs, these fishermen can use alternative power plants in the form of solar panels. This research examines the process of analyzing the performance of solar-powered power plants. The solar panel produces 115.28 watts of power in 1 day. The time required for charging the battery is 5.81 hours/day and the battery endurance time is 4.65 hours in 1 day.

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 study aims to examine the effect of machine temperature on the process of making 3D printing filament from recycled plastic water bottles on filament quality, focusing on tensile testing as the main mechanical parameter. The filament produced from recycled PET (Polyethylene Terephthalate) plastic bottles is used in 3D printing, representing an approach to reduce plastic waste. The filament-making machine's temperature is considered a significant variable that can influence the mechanical properties of the produced filament, including tensile strength. In this study, the Taguchi L4 method was employed, resulting in 12 test specimens with varying machine temperatures (210°C and 220°C), pulling speed (18 RPM and 24 RPM), nozzle temperature (260°C), bed temperature (90°C), print speed (50%), and infill density (107.1%). The results showed that the optimum outcome was achieved in the third experiment, with a combination of 220°C machine temperature and 18 RPM pulling speed, with an average tensile strength of 59.6 MPa. This study contributes to optimizing the process parameters for making 3D printing filaments from plastic water bottles.
