PT Tunas Muda Global Sejahtera which is a subsidiary of PT Tracol Asia Indonesia currently oversees the sand material business line located in the Klaten area, Surakarta, Solo. We have volcanic sand as the basic material that comes from the slopes of Mount Merapi. With a mud content of 5%, the sand material we provide is of good quality to meet the demands and needs of our customers.

In addition, we also provide the procurement of Andesite split stones of various sizes to be supplied to meet the needs of state-owned concrete factories and private concrete factories.
