Antara – The Gadjah Mada University (UGM) in Yogyakarta, together with the National Research and Innovation Agency (BRIN), is collaborating on research to utilize nuclear technology to control population of fruit flies, which are known as the main pests in horticulture. This collaboration will focus on enhancing the competitiveness of local horticultural commodities, especially salak pondoh, which is an icon of Yogyakarta.
"Fruit fly infestations have been a serious obstacle to Indonesian fruit exports," said Suputa, the head of the Master's Program in Plant Pest Science at the Faculty of Agriculture UGM, in a statement in Yogyakarta on Sunday, August 24, 2025, as quoted by Antara.
Suputa mentioned a case in 2016 when exported salak to Australia was destroyed due to the discovery of fruit fly maggots. Since then, Australia has stopped accepting salak exports from the Special Region of Yogyakarta (DIY).
According to Suputa, with the support of nuclear technology, the eggs and larvae of fruit flies inside the salak can be neutralized. "We hope that our fruit products will be accepted by our trading partner countries," explained Suputa. The greatest hope of this collaboration is to help increase the country's foreign exchange earnings through the export sector while also preserving the sustainability of local fruits.
According to Suputa, this research collaboration is an initial and productive step in building research synergy, particularly in the application of phytosanitary and Sterile Insect Technique (SIT) based on nuclear technology for food security enhancement.
Murni Indarwatmi from BRIN stated that the potential for utilizing nuclear technology in the plant protection sector is significant, particularly in post-harvest processes to meet export standards. "The use of irradiation, especially for fruits, is for phytosanitary treatment. With irradiation, radiation can penetrate the fruit and kill the eggs and larvae of fruit fly pests that are hidden," she explained.
Murni acknowledged that there are still challenges related to the public's perception of nuclear technology, which is often associated with bombs or reactor accidents. "In reality, this irradiation does not leave any radioactive substances adhering to the products. The dosage is small and safe, which actually ensures that the exported fruits are free from pests," she said.
