Rajun Butar Butar Email and Phone Number
Hello!I am a fresh graduate major in chemistry at Samudra University, Aceh. I have communicative, responsible, adaptable, teamwork and individual skills, time management, and am proficient in using Microsoft Office. I am interested in contributing to the chemical industry because I have skills in the fields of gravimetric-volumetric analysis, titrimetry, chemistry-physics, microbiology, proximate, and can operate instruments in laboratory. During my studies, I had 2 years of experience working as a basic and organic chemistry laboratory assistant at my college helped the lecturers. Apart from that, I had an internship at PT Suri Tani Pemuka (Japfa Group) for 5 months as a Research & Development and 1 month at Balai Riset & Standardisasi Industri Medan as a Research Assistant. I am looking for opportunities to make a further contribution to the chemical industry to be able to apply my knowledge and talents.
