Abstract

Traditional drying of skipjack jerky is still widely used by MSMEs, but it is highly weather-dependent, prone to contamination, and produces less uniform quality. This research aims to design and test a prototype of an incandescent electric dryer that is simple to operate, provides controlled drying conditions, and is easy to use. The system developed is an insulated cabinet with stainless-steel mesh racks, incandescent light heaters, forced-air circulation, and temperature and humidity sensors, monitored during a 360-minute performance test with sample mass changes. The results showed that the drying chamber temperature remained stable at 43.9–49.3 °C, the relative humidity dropped from about 47% to ±30%, and the jerky mass decreased from ±917 g to ±353 g, with a final moisture content of about 30%. Compared to sun drying, electric dryers provide faster drying rates and more stable drying patterns, making the time to achieve the target moisture content and quality between batches more predictable. These findings show that the prototype is worthy of consideration as an alternative drying technology for seafood processing MSMEs and serves as a basis for further development to improve energy efficiency and product uniformity.

Abstract

The geometry of metal components is an important factor influencing corrosion behavior, particularly localized corrosion. This study aims to analyze the effect of geometric variations on the corrosion rate of carbon steel through a simulated laboratory experimental approach. Carbon steel specimens were fabricated with three different geometries, namely flat surface, sharp-edged surface, and crevice geometry. Corrosion testing was conducted using immersion and potentiodynamic polarization methods in a 3.5% NaCl solution. The analyzed parameters included mass loss corrosion rate, corrosion potential, and corrosion current density. The results showed that crevice specimens exhibited the highest corrosion rate, followed by sharp-edged specimens, while flat surfaces demonstrated the best corrosion resistance. This behavior is attributed to the formation of differential aeration cells and non-uniform current density distribution caused by geometric variations. These findings highlight the importance of considering geometric design in corrosion mitigation strategies for metal components.
