RH.SITH.ITB.AC.ID, Jatinangor –Bioengineering Study Program through the Principles of Bioproduct Separation (BE3204) course holds a guest lecture with the theme “Introduction to Filtration and Downstream Technology” in order to gain insight into Bioengineering students about the application of bioseparation principles in the Bioindustry. The lecture held on Tuesday (17/4) was delivered by the Bioengineering alumni, Widya Pratiwi S.T. and M. Gidry Abdurrazak S.T., who works at PT. Sartonet Filtrasi Indonesia.
Located in the Seminar Room, Labtek 1A, ITB Jatinangor, the guest lecture was opened with a brief welcome from the course lecturer, Dr. M. Yusuf Abduh and continued with a presentation from alumni for 1 hour. In the presentation session, two bioengineering alumni invited students to know more about the 4 main material such as overview downstream process, basic of filtration, an overview of microfiltration and ultrafiltration in biopharmaceutical and pharmaceutical industry. At the beginning of guest lecture, Widya explained that the filtration process used in all types of bioindustry and the processes that occur in the textbook are quite different from the reality that occurs in bioindustry in 2018. She also emphasized the importance of understanding filtration that will help students when they graduate from the study program and work well in the fields of production, quality control, R & D, marketing or other fields in the biotech industry.
In the first explanation of the downstream process in bioindustry, Widya provided an initial description of the concrete process of drug production in the field of pharmaceutical and processes in biopharmaceuticals. This explanation helps Bioengineering students in understanding that in order to produce a product, especially bioproducts, it is important to use the filtration process and the whole process through several stages which are quite complicated with supporting facilities. In the next session, Widya explained about the filtration basis such as the importance of knowing the purpose of product separation and filtration equipment that is suitable for filtration purposes by considering the filter size and membrane material. In the microfiltration explanation, Widya provides knowledge about the basic mechanisms of microfiltration and the material used. Widya also advised that Bioengineering students should know these 2 types of material when doing the preliminary design of bioproduction system in Final Project – II later.
“The important thing that students must know is that the 2 types of material used are membrane filters and depth filters. For the Final Project – II, the material must be compatible with the product that we will produce,” said Widya.
The presentation session then ended with an explanation of the ultrafiltration concept in which Widya demonstrated the device in the form of a cartidge filter and capsule filter to show the filtration device worked directly. Widya also gave an interesting explanation about this tool that what was found in the book was different from the one in reality.
“In theory, the type of membrane used in ultrafiltration is hollow fiber or spiral wound. But in reality, in the industry we find the form of a cassette. This cassette serves to separate particles based on molecular weight,” explained Widya.
During the guest lecture, the conditions looked very interactive where students were enthusiastic to ask about this course. Before the lecture ended, the two alumni also gave quizzes to see how far the students were understanding about the course in this time. After that, the atmosphere of the lecture was even more interesting when stepping on the sharing session between the course lecturer, Dr. M. Yusuf Abduh with alumni who shared the unique experiences of alumni when studied in Bioengineering study program.
At the end, Dr. M. Yusuf Abduh expressed his gratitude to the alumni who would like to share the knowledge gained during their work. The alumni themselves said that sharing knowledge, observations and views on the downstream process in bio-based industries to Bioengineering students was an honor and because of high enthusiastic and curiosity from students during the activity, alumni wanted to provide more course later. Widya and Gidry also advised the Bioengineering students that hopefully the knowledge delivered would be useful especially for the final project where students not only capitalize on theories from books, but could imagine what processes in the industry would be faced in the future.
One of the alumni also represented to give her hope.
“Hopefully, Bioengineering alumni can come back to share and share their experiences and knowledge in both the academic and professional fields of work to the Bioengineering students. With this sharing, I am sure that there will be motivation and shadows in the future that make Bioengineering graduates able to compete with other majors out there, because I think Bioengineering is very broad and very much needed in the world of work. Hopefully the Bioengineering study program will develop towards a better one and can obtain international accreditation later. Aamiin”, closed Widya.
