How did Indian culture and religion influence Indonesia historically, and what examples can we see today?

The legacy of trade between India and Indonesia dates back over 2,000 years through early maritime trade between Indian kingdoms and Java and Sumatra. The ancient university of Nālandā collaborated with the Muara Jambi temple complex. Islam travelled to Indonesia from the shores of India. Indonesian currency, the rupiah, carries Garuḍa, the vāhana of Viṣhṇu. The Borobudur Stūpa, built in the 8th and 9th centuries CE, is the world's largest Buddhist monument with over 500 statues of Buddha. Its geometric design replicates a mandala representing the cosmos.
