Dr. Nurmalia is a faculty member of Product Design Engineering study programme at Universitas Prasetiya Mulya, Indonesia. Her expertise is in the testing and evaluation of engineering products and infrastructure, particularly in non-destructive testing and evaluation (NDT&E). Her work in the past 7 years focused on the development of technologies associated with NDT&E, specifically with ultrasonic evaluation techniques. Her latest research has focused on the application of ultrasonic guided waves for use in pipe inspection, which is also important for inspection of tubes, rods, or any plate structures. She also contributes to the development of an alternative transducer design, i.e. Electromagnetic Acoustic Transducer (EMAT).
In the mean time, she is starting to do research on quantitative inspection of tropical fruits. The research combines mechanical properties inspection, nondestructive inspection, as well as chemical inspection.

By ensuring the integrity of infrastructure and other engineering products, non-destructive testing and evaluation (NDT&E) has an important role in modern society. And as existing structures age, NDT&E plays an even more critical role at ensuring public safety. My work of the past five years focused on the development of technologies associated withNDT&E, specifically with ultrasonic evaluation techniques. Among the variety of evaluation methods, ultrasonic inspection has the advantage of being capable of inspecting entire volumes and through-thicknesses and therefore not limited to surface or near-surface depths of inspected materials – a common disadvantage of other traditional techniques. My latest research in the field of industrial NDT has focused on the application of ultrasonic guided waves for use in pipe inspection. A guided wave is one whose propagation is confined to and guided by the medium being inspected (waveguide), e.g. tubing, piping, rod, or any plate structures. Waves of this kind can propagate longer with less attenuation, enabling the inspection of a wide area in a short period of time. To improve the application of this form of inspection, my recent work has focused on the development of an alternative transducer design – the electromagnetic acoustic transducer (EMAT). Lately I have been expanding my interest into non-destructive of fruits and mechanical testing of plastic recycled products.
