Abstract

Ginger processing in Tambang Village Pudak Ponorogo Regency is still low due to the accumulation of harvested ginger, which on average per house can produce 200 kg of raw ginger. ginger to increase the selling value by utilizing technology. To overcome this problem, the method used is to innovate slicing raw ginger into dry ginger by slicing and drying. This research aims to increase the efficiency of ginger processing through innovative ginger slicing machines. The results of the research show that the machine of ginger slicer is able to increase the efficiency of chopping time by 60 Kg/hour and can produce uniform ginger slices in accordance with market standards. This innovation has had a significant impact on increasing the income and welfare of the people of Tambang Village.

Abstract

The utilization of natural fiber-based composites has emerged as a promising alternative to synthetic materials because of their lightweight, high strength, and eco-friendly characteristics. This research investigates the influence of combining sugar palm fiber and pineapple leaf fiber on the flexural strength and macrostructural characteristics of polyester-matrix composites. Specimens were fabricated using the hand lay-up press technique, while flexural strength testing followed the ASTM D-790 standard. Macrostructural analysis was performed using a macro lens to evaluate fiber distribution, void presence, and delamination. The results confirmed that fiber composition significantly affected both mechanical and structural properties. Among all specimens, the pineapple-fiber-dominant composite (Specimen 5) achieved the highest flexural strength of 80 MPa, whereas the specimen with higher sugar palm fiber content (Specimen 3) showed the lowest value of 59.4 MPa. Improved performance was strongly associated with uniform fiber distribution, effective interfacial bonding, and reduced voids. Overall, the findings highlight the considerable potential of natural fibers as reinforcements for producing strong, durable, and sustainable composite materials.
