Hello, my name is Siti Altirana Anandiwa. I am a fresh graduate with a Bachelor degree of Science from IPB University.As a fresh graduate of the Physics program at IPB University, I have a strong interest in applying physics to develop sustainable products. During my studies, I have learned a wide range of physics concepts. My research experience focused on analyzing the proximate composition and thermal properties of empty palm fruit bunch briquettes mixed with coal for co-firing. This research allowed me to apply my physics knowledge in the context of renewable energy.
