Economic and trade inequality in the northern, central, and southern regions of East Java Province is no longer a secret for the people of East Java. The northern and central regions of East Java are relatively fast growing, compared to the southern regions of East Java Province. This difference in economic and trade development could be due to differences in transportation facilities and infrastructure, especially ports, so the distribution of goods, services, and people from and to the southern region of East Java Province is not smooth. Or it could be due to the absence or scarcity of commodities to be transported from the southern region of East Java Province because they have not been explored and processed and managed optimally.Departing from the economic and trade imbalance in the southern region of East Java Province which is likely due to the lack of development of port facilities and infrastructure, the East Java Provincial Government, in collaboration with the local government and the Central Government, built a Commercial Port in Prigi, Trenggalek Regency, which is located next to the Fish Port. Prigi Niaga Port's capacity is 3000 DWT, located in a bay west of the Fish Harbor. Currently in place are a 10 x 75 m pier, a 8 x 55 trestle, and an 8 x 250 m causeway.This book provides background on construction of the Prigi Niaga Port, the problem of economic disparity, port development planning and policies in East Java Province, accessibility, connectivity, hinterland, opportunities for the Prigi Niaga Port, potential commodities in the southern region of East Java Province, and strategies for accelerating development of Prigi Trading Port in Trenggalek Regency.This book was published in collaboration with Interactive Publications Pty Ltd, Treetop Studio, 9 Kuhler Court, Carindale, Queensland, Australia.
