[Unpad Media Channel] A team of Universitas Padjadjaran students has successfully created an innovative prototype called “PetraScan”, a multiparameter biosensor that applies spectroscopy methods and is integrated into a milking machine. This tool is designed to detect subclinical mastitis in dairy cows through fluorescence and absorbance indicators, offering a breakthrough to improve milk sustainability and productivity.
The interdisciplinary team consists of Athifah Ari Ghumaisha (Informatics Engineering), Muhamad Hilmy Al Hafidz (Biology), Adlina Rohadatul Aisy (Biology), Umar Abdurrahmannasrulloh (Animal Science), and M. Luthfi Firdaus (Electrical Engineering), supervised by Novi Mayasari, S.Pt., M.Sc., Ph.D. The project was developed under the Student Creativity Program for Invention (PKM-KC) and received funding from the Ministry of Education, Culture, Research, and Technology.
The background of this innovation stems from the nation’s vision of realizing Golden Indonesia 2045, where nutrition plays a crucial role in preparing globally competitive generations. However, domestic milk productivity remains low, partly due to limited application of smart farming technologies that integrate animal welfare principles. Research by Nuraini et al. (2023) revealed that 63.42% of dairy cows in Indonesia suffer from mastitis, leading to reduced milk quality and economic losses for farmers.
PetraScan applies fluorescence indicators using acriflavine reagent to stain SCC (somatic cell count) with AS7262 as the sensor, and absorbance detection using LDR as multiparameter technology to enhance accuracy. The device is built with a durable design and food-grade standards, making it ready for broader application in the livestock and dairy industries.
This innovation also aligns with the Sustainable Development Goals (SDGs), particularly Goal 3 (Good Health and Well-being) and Goal 9 (Industry, Innovation, and Infrastructure). The team believes PetraScan demonstrates how education, science, and technology can contribute to building a better future.
