Yusuf Wibisono, STP, MSc, PhD, a lecturer at Faculty of Agricultural Technology Universitas Brawijaya (FTP-UB) presented his research on non-medical application OCT at 2nd International Conference on Desalination Using Membrane Technology. The event was convened in Singapore for four days (26-29/Jul/2015). Research paper he presented orally entitled "Mesoscale in-situ Inspection Using Optical Coherence Tomography During Two-Phase Flow Cleaning for Biofouling Removal in Spiral-Wound Membrane Elements". Beside that, he was also presented a poster entitled "Two-phase flow for fouling control in membranes".

Optical Coherence Tomography (OCT) is a scanning technology utilizing rays based on low-coherence interferometry to capture three-dimensional picture of an object, commonly in micrometer size. OCT technology has widely used in medical world particularly for diagnostic in ophthalmology, optometry, neurology, gynecology, gastroenterology, oncology, cardiology and dermatology. But in the hands of Yusuf Wibisono, the technology is utilized in non-medical application, that is mitigation the formation of bio-film in membrane module that is used for drinking water process.

OCT technology is able to be used to detect bio-film growth in nano-filtration membrane module and reverse osmosis (NF/RO). If the bio-film flourish then will become bio-fouling and disadvantage since hampering water purification process by NF/RO membrane, thus declining drinking water production level and its quality at once. By utilizing OCT technology, the initial detection can be executed and so membrane module cleaning process can be done punctual and accurate.

OCT non-medical application is still new worldwide. The research of Study Program Head at Agricultural Engineering Master Program was competed with research performed by Singapore, Finland and The Netherlands researchers. The result of research has issued by Water research journal, a journal that according to Thomson Reuters Journal Citation Reports 2015 assessment, has an impact factor of 5.528. OCT News, a portal that especially dedicated for OCT application also published the research result, hereby is the report link:

A conference that was organized by Elsevier, and coordinated by University of Swansea-England, Nanyang Technological University-Singapore and University of Technology Malaysia was attended by hundreds of participants of 44 countries. In the end of the conference, Yusuf was chosen as the participant who was entitled to visit Tuaspring desalination installation in Singapore. The installation was just began to operate in 2013, and is the largest Asian seawater desalination installation with production capacity of 318.500 m3 drinking water each days. With such large desalination process, Singapore prepared to be a country that its water resources sustainability is guaranteed, and started to disposes its dependency to Malaysia in providing drinking water necessity for Singaporean. The seawater process installation that is tightly guarded by armed security, utilize ultra-filtration technology as pre seawater processing. Moreover, utilize also two phases reverse osmosis membrane technology (namely high pressure and low pressure) to eliminate salt component of the seawater to produce high quality and clean drinking water.
