On a rainy afternoon of February 29th 2016, SBE UISC held its very first guest lecture, entitled “Industrial Biotechnology: Enzyme Immobilization”. By 4 pm, members and non-members of SBE registered themselves at the entrance of room K106, welcomed by free snacks they ultimately enjoy. After that, the guests are seated and ready to learn about the knowledge from the speaker of the event. Even though there was heavy rain outside, it only gave the guests more reason to come to attend the lecture.

The speaker himself is none other than Dr. Siswa Setyahadi from BPPT, introduced by the lovely host from SBE UISC. Then Dr. Siswa introduced himself as well, where he explained that he is one of the researchers from BPPT, focusing on biotechnology especially the usage of enzyme in industrial sector. Professor Misri also dropped by to see Dr. Siswa’s lecture.



The lecture consisted of the usage of enzyme in general and in industrial sector, how it will benefit us and why it wasn’t used as much as it could. If we use enzyme in a massive scale, it will help to reduce waste for its renewable and biodegradable characteristic, reduce cost for its relatively normal condition, and help improve yield in both quantity and quality. However, there are some things to consider such as contamination, protein allergy, and the high cost of the enzyme itself. By using enzyme immobilization methods, we will be able to create products with high profit yet low waste.

Enzyme immobilization is a method in which enzymes are physically confined while keeping their catalytic activities. Some of the most famous applications is stable fibers, tablet disintegration, dietary products, scaffolds, etc. There are many types of enzyme immobilization methods, such as adsorption, covalent binding, entrapment, encapsulation, and cross linking. However, there are some engineering and commercialization consideration when using these methods. But if handled correctly, enzyme immobilization will bring us higher productivity, larger space and time reduction, and more economical process.

At the end of the lecture, Dr. Siswa concluded that enzyme immobilization methods are developing rapidly to meet industrial requirements. Many scientists are still looking for the best method to immobilize enzymes. Hopefully such method will be available soon in the future for us to use.
