Guest Lecture Prof. Ni Nyoman Tri Puspaningsih: Pengembangan Teaching Industri Untuk Enzim

The UNEJ FMIPA Chemistry Department held a guest lecture by presenting Prof. Dr. Ni Nyoman Tri Puspaningsih, M.Si., Deputy Chancellor for Research, Innovation, and Community Development, Airlangga University (29/1). Presenting material entitled “Pengembangan Teaching Industri Untuk Enzim” Prof. Ni Nyoman explained the importance of enzymes for various environmentally friendly chemical and biotechnology industrial needs. The guest lecture was held in the FMIPA Physics auditorium with participants from students and lecturers from the Chemistry Department. “As a start, I will introduce microbial biotechnology, the added value of commercial use of microbes, and micromodification,” said the coordinator of COVID-19 research products at UNAIR during the last pandemic.

It was explained that microbial products are enzymes and have great potential for various companies. “Enzymes are an ideal product that can be applied to several companies; paper is one of them, as well as pharmaceutical companies,” he said. Prof. Ni Nyoman, who is also a colleague and lecturer of Prof. Dr. Anak Agung Istri Ratnadewi, S.Si. The Chair of the FMIPA Chemistry Department explained further that the fermentation parameters of enzyme products need to be prepared well, from nutrition to the type of fermentation chosen.

“Microbial nutrients, which are usually called nutrients, are needed by cells; macronutrients are nutrients that are needed in large quantities; and the opposite is called micronutrients,” he explained. Also mentioned are culture media that are useful for growing microorganisms in the laboratory, all of which are summarized in the research carried out in the laboratory. PUIPT-Biome Preteomics. And this research has resulted in several patents in 2011, 2016, and 2021.

At the end of the guest lecture, participants were given the opportunity to ask questions. Enlightenment from Prof. Ni Nyoman opened up more insight into enzymes and their development. He even gave interested students the opportunity to join in his research as an intern or to visit his laboratory. Head of the Chemistry Department, Prof. Dewi at the end of the event expressed her gratitude for the knowledge and time provided to Chemistry students and lecturers to make the guest lecture possible.
