Navigation Channel Capacity Modeling: A Case Study for Balikpapan Bay

Vessel traffic flow in Balikpapan Bay will increase to follow the nation's new capital city planning development in East Kalimantan affects the demand for development on a large scale from all around Indonesia to the new area in East Kalimantan. This final project aims to determine the maximum number of vessels passing a particular channel per unit time. The discrete simulation method will use Anylogic software to determine the channel capacity with the channel length, vessel safety distance, and vessel velocity. The number of vessel arrival to Balikpapan Bay is estimated using the Forecasting Method and Moving Average Method. The results showed that the recommended channel capacity is 74 units/day or equal to 27.010 units/year with a utility rate of 80%. That maximum number of vessels entering the channel can guarantee the safety level of shipping activities and reduce queues that cause congestion and costs arising from long waiting times for channel services and the stability of port workload. Based on these conditions, Balikpapan Bay could accommodate vessel arrival during materials and heavy-duty equipment for the nation's new capital city planning development until 2032. The total number of vessel arrival is 24.282 units and a utility rate of 72%.
