INTRODUCTION
The shipping industry is one of the maritime sectors that has received priority for globally competitive development.
The government has established the maritime sector as one of the priority areas of national development.
This has a positive impact on Arum ET AL.
increasing the competitiveness of the shipping industry or shipyard.
The performance of the national shipping industry continues to develop, including an increase in the number of shipyards and ship production capacity.
In January 2023, the Directorate General of Sea Transportation.
Directorate of Ports of East Java Province, noted that in the field of business Docs and Shipyards have reached 20 companies, with eight companies included in the Special Terminal (Tersu.
and 12 companies included in the Terminal for Own Interests (TUKS).
However, there are still many companies that the Directorate Genearal of Sea Transportation of East Java Province has not Shipyards in Indonesia have experience building various types of ships, ranging from passenger and cargo ships to special purpose ships with the largest graving dock facilities .
000 DWT) .
A shipyard is specially made and equipped with various facilities to support the making, repair, and maintenance of ships.
A shipyard company must have a warehouse.
The warehouse is important in the shipyard because the warehouse is a storage area for all types of raw materials needed by the company and shipyard.
Shipyard companies certainly have a recording system in warehousing activities used to manage raw materials inventory, ranging from incoming and raw materials in the warehouse to outgoing raw materials.
The inventory system will run effectively in recording and controlling the inventory of raw materials if supported by good system development.
Based on these problems, an inventory management information system has been developed in the warehouse of a shipyard This system makes it easier for operational and construction managers to record inventory without going through a complicated documentation process and missing data.
In addition, it also makes it easier for operational and construction managers to control the stock of raw materials/materials in the warehouse, such as the minimum-maximum stock of raw materials/materials that should be in the warehouse.
It can make it easier for company leaders to find out the inventory of raw materials, which can be done from anywhere and anytime without having to receive Excel files recording the inventory of raw materials.
In controlling the raw materials inventory, it is necessary to analyze the calculation using the Min-Max Stock Level method, which can show the minimum, maximum, and safety stock of the required raw materials.
The development of the system cannot be separated from maintaining the quality of the existing system and continuing to develop it to make the companyAos management system run effectively and efficiently.
After measuring the quality of the development of this inventory management information system, it is hoped that the company can monitor all inventories of company raw materials in warehouses and offices, which can increase employee responsibility and productivity.
This research aims to improve performance in inventory management using the min-max stock level method with the inventory website system and measure the quality of system development to facilitate companies in controlling inventory activities to be effective and efficient.
Measurement of the quality of system development can be tested based on the ISO 25010 standard feasibility test, which will determine the level of feasibility of the website-based inventory system used by the company.
The feasibility test is based on the ISO 25010 standard and has eight aspects.
The eight aspects include functional suitability, performance efficiency, compatibility, usability/operability, reliability, security, maintainability, and portability.
This research uses three aspects: functional suitability, usability, and maintainability.

Furthermore, testing based on the ISO 25010 standard can ensure that the quality of the inventory management information system is suitable for shipyard companies.
MATERIAL AND METHOD
Supplier An inventory control system is needed to help provide information quickly and accurately to the company.
Inventory control is an activity that aims to determine the level and composition of raw material inventory so that the company can effectively and efficiently protect the smooth production, sales, and spending needs.
Inventory is one of the important components for the sustainability of the company because inventory can show everything or organizational resources stored in anticipation of meeting demand.
Inventory is commonly used to solve problems related to controlling raw and finished raw materials in a companyAos activities.
Therefore, inventory control must be carried out in such a way as to serve the needs of materials or raw materials appropriately and at a low cost .
Control is the process of observing the implementation of all organizational activities to ensure that all work being carried out is in accordance with the predetermined plan.
Control is related to comparing events with plans and taking corrective action against events that deviate from the plan.
Control is needed to see the extent to which the results have been achieved, whether they are in accordance with the plan or there are gaps due to deviations .
Minimun Maximum Stock Level The Min-Max Stock method maintains raw material inventory to support smooth production.
According.
in inventory control using the min-max stock method includes several stages:
Determining Safety Stock Safety Stock is extra inventory that needs to be added to ensure that there is always enough stock in case of additional need or delays in the arrival of raw materials.
Safety Stock = .

cE) = Maximum Oe Minimum The maximum and minimum inventory quantities determine the concept of maximum and minimum inventory.
If the inventory has reached the minimum amount, the purchase of raw materials is immediately made until the number of raw materials reaches the maximum inventory.
If the inventory of raw materials has reached the maximum, the purchase is stopped.
When the raw materials in stock are used continuously, the inventory will reach the minimum point again, and so on.
This concept was developed based on the idea that to maintain the continuity of a companyAos operations, certain raw materials in minimum quantities Arum ET AL.
FIGURE 1 Characteristics of Software Product Quality Model should be available in stock to be used immediately when needed.
However, the raw materials stored are not allowed to be too much, so there is a maximum value.
Software Testing Based on ISO 25010 Software testing is done on the shipyard companyAos inventory management information system.
Software testing is critical to software quality assurance and presents specifications, design, and coding.
Three important things need to be considered in analyzing software quality, namely effective software processes, useful products, and adding value to producers and users .
ISO/IEC 25010 is developing the ISO/IEC 9126 version.
The ISO/IEC 25010 model has quality characteristics that can be considered when evaluating software .
The software product quality model is a model that can only be applied to software products because most of the sub-characteristics are related to software and systems.
The software product quality model consists of 8 quality characteristics .
unctional suitability, performance efficiency, compatibility, usability/operability, reliability, security, maintainability, and portabilit.
shown in Figure 1 below:
Characteristics and sub-characteristics in the Software product quality model which consists of:
Functional Suitability is a characteristic to measure the extent to which a product or system provides functions that meet needs when used under certain conditions.
Performance Efficiency is a characteristic to measure performance relative to the resources used under certain conditions in a system.
Compatibility is a characteristic to measure the extent to which a system can exchange information with other systems and perform the required functions when sharing the same hardware or software environment.
Usability is a characteristic that measures how users can use a system to achieve specified goals with effectiveness, efficiency, and satisfaction in a specific context.
Reliability is a characteristic to measure the extent to which a system can perform a function under specified conditions for a specified period.
Security is a characteristic to measure a system in protecting information and data so that the system has a level of data access according to the type and level of authorization.

System quality measurement can be done separately based on the eight types of characteristics previously described.
Therefore, this research will measure system quality based on functional suitability, usability, and maintainability characteristics.
Functional suitability characteristics present the extent to which a product or system provides functions that can meet the needs expressed and implied under certain conditions.
Usability characteristics explain the systemAos feasibility, including the categories of very less feasible, less feasible, quite feasible, feasible, or very feasible, which depend on the percentage of the calculation results from the questionnaire.
The maintainability characteristic shows the system will respond well if the user inputs an error.
Testing in this study was carried out on Functionality Suitability.
Usability, and Maintainability.
In the functional suitability aspect, using a research instrument as a test case with a Guttman scale.
The Guttman scale is used to get a firm answer to a problem that wants to be stated.
This type of measurement scale gets a firm answer: "Yes" or "No".
yes is worth one item, and no is worth zero for each item.
Test cases were given to 2 media/system experts, while percentages for each study can measure the results of the tests carried out by validators.
In this case, the Warehouse Admin is validator 1, the Director is validator 2, the Project Manager is validator 3, and the Finance Manager is validator 4.

RESULT AND DISCUSSION Minimum Maximum Stock Level Safety Stock is inventory stored in excess of expected demand due to variable demand and/or lead times .
Implementing the Safety Stock method is an explanation of the calculation of the amount of safe stock inventory that must be in the warehouse of the shipyard company to avoid delays in production materials.
The data used in this calculation is on the need for materials or materials for producing fiberglass-based ships in 2022.
The materials or materials used are described in Table 5 below:

The above calculations show that the final resin stock in 2022 is very large compared to the safety stock.
For this reason, shipyard companies need to take action so that inventory materials are not overstocked in the following year.
The number of reorders is 12 Liters of resin, which means it does not exceed the maximum stock,k, so the value shown by Q is still normal.
Table 7 results from calculating safety stock using the Min-Max Stock Level method on fiberglass ship raw materials for shipyard companies in 2022.

TABLE 8 The results of testing the functional suitability aspect Amswer Yes Total Percentage Warehouse Admin Score by Validator Director Project Manager Finance Manager that the amount of raw material inventory at the end of 2022 is much higher when compared to the safety stock calculation.
This shows that the Min-Max Stock Level method was not previously carried out on the raw materials used for producing fiberglass ships at the shipyard company.
This results in an excess inventory of raw materials and causes the companyAos investment to settle so that the company purchases raw materials or produces raw materials every time production starts.
The analysis of the calculation of safe inventory or safety stock for raw materials for the production of fiberglass ships states that the amount of inventory controlled by the min-max stock level method produces more efficient results than the companyAos final inventory.
recommend that companies apply the min-max stock level method effectively for the coming period so that there is no waste of storage space and that raw materials can be ordered at the backorder level so that there is no delay in their arrival.
Testing System System testing is carried out to determine whether the system is acceptable, whether the system is feasible to use, and determine the effectiveness and efficiency of the system created.
The results of system testing based on the ISO 25010 model quality standards using aspects of functional suitability, usability, and maintainability are as follows:

CONCLUSION
Research on inventory control management of shipyard companies based on the website.
Control related to the inventory of raw materials in the warehouse using an analysis of calculations using the Min-Max Stock Level method, which shows the minimum, maximum, and safety stock of the required raw materials.
Then.
I measured the feasibility of a website-based inventory system using ISO 25010 standards.
Based on the analysis of safety stock calculations using the Min-Max Stock Level method on fiberglass ship raw materials in 2022, the amount of raw material inventory at the end of 2022 is much higher than the safety stock calculation.
Raw materials have Arum ET AL.
the greatest usage value, namely resin, which has a final inventory amount in 2022 of 195 liters and a safety stock calculation of 08 liters.
This shows that the Min-Max Stock Level was not previously run on the shipyard companyAos raw material inventory, which resulted in an excess inventory of raw materials and caused the companyAos investment to settle.
So that the company purchases raw materials to produce raw materials every time it starts production.
It is hoped that the company will apply the min-max stock level method effectively for the coming period.
So that there is no waste of storage space and can order raw materials at the backorder level so that there is no delay in raw materials.
Based on testing based on ISO 25010 carried out on the inventory management information system of the Shipyard Company, the following data is obtained:
Based on the functional suitability aspect, a percentage 100% is obtained for each validator.
Based on the usability aspect, a percentage of 92.
2% was obtained.
Based on the maintainability aspect, the shipyard companyAos inventory management information system is included in the easy-to-maintain category.
The system assessment results based on ISO 25010 suggest that the website-based inventory system is feasible for helping warehouse staff perform more effectively and efficiently.
