I am a Ph.D. student at Oregon State University, USA. I was also appointed as a teaching staff and researcher at Universitas Sebelas Maret, Indonesia. I have broad interests in animal nutrition aspects both in poultry and ruminants. Currently, I am researching the utilization of spent hemp biomass as a feed for livestock for my PhD project. This research aims to uncover the potential use of hemp byproduct generated from cannabidiol (CBD) oil extraction as a feed ingredient for ruminants by investigating the impacts on production, metabolism, health, and accumulation of cannabinoid in foods producing animals. The systematic measurement of cannabinoid is particularly important to assess the risk and exposure on consumers as well as to provide data for FDA for its safety consideration.
