As the main gate for domestic and international cargo transport as well as the largest Indonesian seaport, Tanjung Priok Port (TPP) plays an important role in Indonesia logistics. To facilitate the growth and reach the optimum usage of the current TPP development, transportation infrastructure development shall also be improved to keep up with the supply chain and demand. Since the road transportation is getting unreliable these days with all of the heavy traffic along the route, another transportation option, e.g., inland waterway, has brought a new hope while Cikarang Bekasi Laut (CBL) channel provides a potential solution. Many factors have made inland waterway in Indonesia are underdeveloped, among them are limitations on waterway elements, such as discharge, width, depth, air draught clearance and radius curvature, that make impossible for vessels to sail. The present study is presenting about the elements of CBL waterway and how to optimize the inhibiting factor on CBL channel which made the existing channels can be utilized, as well as inland waterway alternative transportation modes. The research was done by carrying benchmarking against three waterway international standard designs, namely PIANC, ASCE, and Rijkwaterstaat (RWS), then simulating the water discharge condition using HECRAS V4.1 software, and at last validating result with expert in-depth-interview. The result shows that CBL can be used as logistic transportation mode with some optimizations regarding the waterway elements, such as depth, width, air draught clearance and channel bend-radius. And among others, a design using the RWS standard requires the smallest dimension than other standards using the same vessel reference. In addition, a comparison of two reference vessels, namly container vessels with a capacity of 96 TEUs and 144 TEUs, was evaluated based on the required channel dimensions and costs for the channel development construction, to obtain the most optimum design according to its conditions.
