## 2 The Indonesian \"Sea Toll\" Program
What is the percentage of the total capacity installed in the loading/unloading process, the level of productivity, the effectiveness of the administrative/documentation process, the speed of access to data and information systems, water entrance transportation, and of course the effectiveness of other supporting stakeholders into important sub-variables in the level of service reliability port? While routine and scheduled services, especially related to alternative service routes, the size (size) of the ship and its cargo, rely on the effectiveness of the window system and _INAPORT_ (management information system). The integration of supporting transportation modes for port access with land areas or islands makes service more effective and efficient. Both from the coast, river, land and pipeline access. If we look in detail at the variable shipping industry as shown in Figure 3, there will be many supporting sub-variables that are interrelated. So that in the decision making process, there are many variables that need to be taken into consideration in several alternative decisions. \begin{table}

Sea Toll System for Passenger & Cruise Services: Description, Definitions and Supporting Variables Introduction  
The sea toll system also does not only serve the container sector, but inter-island and cruise passenger transportation services are also included in the direction of the system policy. There are four variables included in the passenger and cruise service support system, namely service specialization, commercial/tourist destinations, travel/leisure shipping, and supporting transportation integrations as shown in Figure 4 below. Sea transportation services for passenger and cruise sectors over the last few years have faced significant challenges, both internally and externally. Competition with the air transportation market is the biggest challenge for the island nation, because the large number of low-cost flights between islands makes alternative air transportation more promising for consumers. However, in the concept of sea toll, passenger and cruise services need to slightly change the target market and its service model. Starting with service specialization, service providers need to group services into several alternative services that consumers can enjoy. Service specialization will distinguish the quality of these services with other transportation services. Focusing on these services can be seen in other variables, such as services which focuses on the tourism destination sector or commercial demand, then shipping that serves passengers who want to

And of course, the transportation service model that is integrated with other modes of transportation on land will greatly help and increase the satisfaction of passengers. Investigation of the Impact of the Implementation of the Sea Toll System on the Development for the Saport System  
The implementation of a \"sea toll\" system in an archipelago country has not been addressed clearly in previous studies. [PERSON] et al. [16] only addressed the issue of marine highway transportation in relation to toxic inhalation of hazardous materials in the North American region.
