Abstract

The main problem in drying crackers is that drying is not uniform and still uses solar heat. In the rainy season, the process of drying crackers cannot be done quickly or takes longer, thereby reducing the amount of cracker production in cracker MSMEs. The solution to the problem in the drying process is to use technology in the form of a cracker drying oven. The cracker drying oven was made at the UMKM Kerupuk Fantasi location so you could try it straight away. From the experimental results it is known that the drying process at a temperature of 75˚C results in a greater reduction in cracker weight than the drying process at a temperature of 70˚C. The drying process in a cracker drying oven is carried out for 3 hours to get perfectly dry crackers. Drying time using a cracker drying oven is faster than drying time using solar heat. By reducing drying time, cracker production capacity will increase.

Abstract

Technological advancements, including 3D printing, enable the creation of prototypes from digital designs using 3D printers. A popular method is Fused Deposition Modeling (FDM) with thermoplastic materials such as Acrylonitrile Butadiene Styrene (ABS), valued for its quality and affordability. In 3D printing, nozzle temperature and infill type influence the mechanical properties of printed objects. This study aims to determine the tensile strength of ABS with variations in nozzle temperature and infill type. Tensile test results show that a 230°C nozzle temperature produces higher yield strength for most infill types compared to 240°C. The 240°C setting tends to increase maximum tensile strength for grid and concentric infills, but not for gyroid and lines. The concentric infill type exhibited the highest elongation at both temperatures, indicating greater ductility compared to other infill types. These findings are expected to serve as a reference for optimizing printing parameters.
