Mechanical engineers create solutions and solve problems, playing a central role in the design and implementation of moving parts in a range of industries. Mechanical engineers provide efficient solutions to the development of processes and products, ranging from small component designs to extremely large plant, machinery, or vehicles. They can work on all stages of a product, from research and development to design and manufacture, through to installation and final commissioning. Most industries rely on a form of mechanical systems and mechanical engineering is thought to be one of the most diverse of all engineering disciplines.
Last week, the Faculty of Engineering and Technology at Sampoerna University had the honor of having Mr. Rodyan Gibran Sentanu, one of Indonesia’s successful Mechanical Engineers, as a guest lecturer on the virtual Senior Colloquium at FET. “Since I was in high school, I always had the strong will to pursue a career as a Mechanical Engineer, especially in the medical and healthcare industry,” uttered Mr. Gibran.
Mr. Gibran was accepted at ITB School of Electrical and Informatics Engineering and only spent 6 months studying at ITB before he had rewarded a scholarship to study at Chiba University in Japan. He flew to Japan in 2006 and took Mechanical Engineering major for his undergraduate and master’s degrees. During his studies at Chiba University, he conducted numerous researches for medical devices, became the chairman of Persatuan Pelajar Indonesia di Jepang, and in 2017, won the Good Design Award in the category of Medical Equipment and Facilities from the Japan Institute of Design Promotion.
“I want to make solutions that will help Indonesia,” remarks Mr. Gibran. This is becoming his main purpose in having a career in mechanical engineering. He wants to create devices that eventually will be applicable in Indonesia to help provide solutions, particularly in the medical and healthcare industry. This purpose wasn’t just coming out of interest, it was also coming out of the personal experience. Mr. Gibran’s sister was diagnosed with congenital heart defects since she was little. At one point, she was referred for a cardiac surgery whereas Mr. Gibran knew that in Japan, this kind of procedure wasn’t needed. The lack of medical devices and skills in Indonesia at the time created grave concerns for him, thus his purpose of giving better solutions for Indonesia’s medical and healthcare industry.
Mr. Gibran explained the non-doctors role in healthcare. The role is based on EBM (Evidence-based Medicine) that consists of the patient’s values, clinical expertise, and best evidence. And based on the book of “Evidence-based Medicine – How to Practice and Teach EBM”, it is the integration of individual clinical expertise with the best available clinical evidence from systematic research.
During his lecture, he mainly shared his experience working at Terumo. Terumo is the biggest medical and healthcare device company in Japan. He was part of a team that developed the VISICUBE (a medical electronic equipment) and AltaView (a catheter) which are used for intravascular ultrasound (IVUS) for Coronary Artery Disease (CAD). The IVUS machine is used to replace the conventional, non-computer aided design angioplasty. This device wasn’t actually the first IVUS device Terumo had produced, it was an advancement of the previous device with the difference of the 60 MHz transducer frequency, while in the previous one was only 40 MHz, the upgrade makes the ultrasound picture quality is clearer and highly accurate. He also explained about the medical development process which are:
- User needs
- Design input
- Design process
- Design output
- The result: Medical device
At the end of his lecture, Mr. Gibran took the time to give assignments to SU FET students for to develop a thermometer gun using the 5 steps process: defining the user needs, defining the design input, defining the design process, evaluation of the design output through verification, and finally evaluation of the final product through validation.
