The combination of nickel-copper (Ni-Cu) in the industry, known as Monel (70Ni-30Cu), is typically produced through casting. However, as known, the casting process requires very high energy. Therefore, alternative methods are needed to obtain Ni-Cu alloys, one of which is electroplating. This was conveyed by the doctoral candidate Cahaya Rosyidan in a dissertation entitled “Electrodeposition Process and Characterization of Ni-Cu Alloys on Aluminum with Various Current Density Variations” during the open defense examination at the University of Indonesia, chaired by the Vice Dean 1 of the Faculty of Mathematics and Natural Sciences, Prof. Dr. rer. nat. Budiawan.

Acting as the supervisor: Dr. Budhy Kurniawan, M.Si, co-supervisor: Prof. Dr. Bambang Soegijono, M.Si. Meanwhile, the examiners were: Dr. Anawati, Prof. Dede Djuhana, M.Si, P.hD, Prof. Setia Budi, and Dr. Ferry Budhi Susetyo. In this open examination, the doctoral candidate successfully completed the study in 7 semesters with a cum laude predicate.

Congratulations and best wishes to Dr. Cahaya Rosyidan, S.Si, M.Sc.
