IOT-BASED CONTAINER MANAGEMENT INFORMATION SYSTEM INSTACKING YARDS TO IMPROVE CONTAINER SHIPMENTS IN SUPPORTING ECONOMIC GROWTH

IN THE ERA OF SOCIETY 5.0

background

This positioning makes Indonesia a logistics center for global imports and exports, with 92% of goods transported via container-type sea transportation.
In 2025, Indonesian ports were congested due to excess arrivals and no real-time monitoring, causing delivery delays and higher prices for basic goods.
The Surabaya Container Depo experienced a 20% decrease in available containers.

research goal

SACON facilitates expedition parties in monitoring goods, as well as booking space on ships and scheduling ships.
Users can access it anytime and anywhere.
SACON can inform users about ship departure and arrival schedules.
Cost estimates can minimize price monopolies and standardize freight rate determination.

sacon architecture System

EXPEDITION > SHIPPING COMPANY > CONTAINER station

SACON is a smart application that is intended to connect 3 (three) parties, namely the Expedition, Shipping Company, and Container Station in order to facilitate the operational flow system of containers.

In this case, the data entered by the expedition party will be processed by the shipping party or the depot party so that it will be directly connected. This happens when the expedition party chooses a service. After success, it is directed to fill in the required personal data and proceed to payment. After payment, the data enters the depot master data and is reconfirmed through the application so that Shipping Instruction appears. This process will make it easier for the expedition party because of the efficiency of time and cost.

Expedition parties can choose their shipping schedule.
Enter load type and quantity details.
Select the required service type.
Fill in sender/recipient data and submit to the shipping company for a shipping instruction document.
The shipping company forwards the document to the designated bank for payment proof.
The depo receives cargo data, checks conformity, and processes SPK; unmatched containers are returned.
The app features: container booking, ship schedules, warehouse capacity info, container tracking, tariff calculation, and general info.
Information on main regional commodities is also provided

benefits & cost analysis

A BCR of 1.31 confirms that benefits outweigh costs

Components	Descriptions	Values
Benefits	Costs incurred before application	$ 32,734.00
	Costs incurred after application	$ 14,148.00
	Value	$ 18,585.51
Costs	Application Development Cost	$ 8,898.09
	Application Operating Costs	$ 4,945.32
	Maintenance Costs	$ 14,148.49
	Value	$ 27,991.90
BCR	Benefit/Cost	1,31

The implementation of the new application yields a clear financial advantage over continuing without it. Although the total cost of acquiring and maintaining the system must be borne upfront, the annual cost savings-amounting to $18,000 more than offset these expenses. Beyond the bottom‐line impact, users benefit from dramatically reduced operational time, a more intuitive interface, and seamless integration with existing systems.

When we compare benefits to costs using the Benefit–Cost Ratio (BCR), we arrive at a value of 1.31; since any BCR greater than 1 indicates that benefits exceed costs, this result confirms that the application is not only justifiable but actually a worthwhile investment.

conclusion

Based on the results and discussions related to the design of the SACON application which can optimize the delivery of goods through a container management information system in the IoT-based stacking yard in the sea toll concept, several conclusions can be drawn as follows:

It can reduce waiting time in container operations by providing important information such as ship schedules, estimated costs, and complete cargo data.
It can be accessed anytime and anywhere.
the integration and digitalization, SACON helps many parties manage logistics operations in a more effective and efficient way.
Fully support the government’s Sea Toll Program by helping reduce the gap between cargo readiness and available ships.
Based on a BCR analysis of 1.31, SACON is worth pursuing, developing and ready to be implemented.
