Article delves into the intricate interplay of friction in fiber-reinforced polymer (FRP) composites, focusing on elucidating interfacial behavior. This study investigates the complex interactions between fibers and polymer matrices, exploring the factors influencing frictional properties at the interface. Through theoretical modeling, experimental analysis, and computational simulations, the research aims to unravel the underlying mechanisms governing friction in FRP composites. By gaining insights into interfacial behavior, this study contributes to enhancing the design, performance, and durability of FRP materials across various applications.

Fiduciary guarantees are material guarantees that are most widely used by banks. Fiduciary guarantees have been used by the Indonesian people since the Dutch colonial era. Based on the Circular Letter of the Directorate General of AHU Number AHU-06.OT.03.01 of 2013 concerning the Implementation of the Electronic Fiduciary Registration Administration System, registration of Fiduciary guarantees is no longer carried out at the Fiduciary registration office but is registered on the official website, namely https://Fidusia.ahu .go.id The implementation of the elimination of Fiduciary guarantees registered in the online system is the obligation of the Fiduciary recipients, but in practice there are still Fiduciary recipients who do not fulfill their obligations to notify the removal of Fiduciary guarantees after the Fiduciary giver pays off their debts. There is no sanction that regulates if the Fiduciary recipient does not notify the cancellation of the Fiduciary guarantee which results in this obligation being not adhered to. The method used is the method of writing empirical law. The results that can be concluded in this study are that if the Fiduciary recipient does not notify the deletion of the Fiduciary guarantee, then the Fiduciary guarantee concerned cannot be re-registered.
