Abstract

The development of technology is increasingly advanced in this modern era, making human life inseparable from the use of machines. These machines must have various spare parts made from steel/iron. In addition, the machining production of these machines is made of steel / iron which can be corroded. Corrosion is a decrease in metal quality caused by the environment or chemicals and affects the condition of a material. The way to overcome the occurrence of corrosion in iron, especially engine spare parts and machining production results is by designing and making corrosion rate inhibitor storage automation as a storage medium for engine spare parts and machining production results. The design of this machine is carried out in several stages, namely planning, design, manufacture, and testing. This research was conducted with the parameters of the results of spraying lubrication and temperature control. From the results of experiments that have been carried out, this storage automation is able to spray lubrication in accordance with the timing that has been set and is able to control the temperature in the storage so that the tool is able to inhibit the rate of corrosion on the workpiece.

Abstract

Graphene oxide (GO) is a promising nanomaterial for membrane-based desalination due to its tunable interlayer structure and abundant surface functionalities. This study synthesized and characterized a graphene oxide titanium dioxide (GO–TiO₂) composite membrane via vacuum-assisted filtration to enhance seawater desalination performance. Characterization using XRD, FTIR, SEM, and contact angle analysis confirmed uniform TiO₂ incorporation, which expanded GO interlayer spacing from 0.77 nm to 0.90 nm, increased hydrophilicity, and improved structural stability. Forward osmosis (FO) tests using 3.5 wt% NaCl feed solution showed that the GO–TiO₂ membrane achieved over 99% salt rejection and a 125% increase in water flux compared to pristine GO membranes. TiO₂ acted as a nano-spacer and hydrophilic agent, reducing GO restacking and facilitating water transport. These results indicate that the GO–TiO₂ composite membrane offers enhanced permeability, selectivity, and durability, making it a promising candidate for sustainable seawater desalination.
