INTRODUCTION
The rapid development of information technology has an impact on various changes in aspects of life (Fauzi et al.
, 2.
The existence of the internet supports the development of technology by providing convenience in finding information in the current era of globalization (Lestari, 2.
Information technology has opened many new pages, especially in the community (Ahadiyah, 2.
Basically, the existence of technology will make it easier and help humans in carrying out something (Salsabila et al.
Information technology is a technology used to process data, process, obtain, compile, store, manipulate data to produce quality information for personal, business, government purposes in decision making (Cholik, 2.

Information technology is needed in business development to make it easier for business people to make transactions and sales (Sulaeman, 2.
One of the information technologies accessed via the internet is the According to Hakim & Murdiani .
, websites are used to display information in a network environment.
Websites have functions as educational media, communication media, promotional media, information media, and marketing media (Hasugian, 2.
Websites have many benefits, including being a means of online learning, promoting institutions, displaying institutional achievements, and as an information center that can be reached by anyone (Sangkalibu & Saputra, 2.
Websites have become one of the most useful tools in business strategies that aim to increase company competitiveness, and also to attract consumers (Aditya & Rusdianto, 2.
An informative, responsive, and user-friendly website can increase consumer confidence in a business and can expand market reach (Setiawan et al.
, 2.
The development of websites in Indonesia can be seen through the use of domains (.
Table 1.

domain has increased significantly from 2012 to 2024.
In 2024, the use of this domain increased to more than one million domains.
Overall, the use of websites with the (.
domain is increasing continuously.
This reflects the increasing needs of the community and business actors for the use of websites that are growing.
One of the companies that uses a website in running a business is CV Sentosa Abadi Steel, hereinafter referred to as CV SAS.
This company is an Iron and Steel supplier located in Sidoarjo Regency.
The company began operating in 2018 by selling various steel and iron products, such as mild steel.

In Figure 1.
1 above is the appearance of the website owned by CV Sentosa Abadi Steel.
It can be seen that the website only has four main Navigation Menus, namely AoHomeAo.
AoNewsAo.
AoProductsAo, and AoContactAo.
There is no search feature or other additional menus that can help users find information more quickly and efficiently.
Through open and in-depth interviews with the CEO and marketing staff of CV Sentosa Abadi Steel, it was conveyed that the navigation structure on the current website is still inadequate in presenting information related to products and companies They consider that the current design has not met the needs of users in terms of ease of access, clarity of information, and overall user Therefore, the company submitted a request to redesign the During the requirements gathering process, the CEO and Marketing Staff specifically requested that the website be equipped with Frequently Asked Questions (FAQ) and Search features placed in the Header section, to facilitate visitors or users in finding relevant information about the company and its products.
This redesign is expected to produce a website that is not only visually appealing, but also superior in terms of functionality, accessibility, and navigation.
The Double Diamond framework developed by the British Design Council UK in 2005 was used in the redesign of the CV SAS website.
According to Norman .
Double Diamond was chosen because it gives designers freedom from restrictions and evaluates a design that aims to determine the weaknesses and strengths of the design so that it can be improved and suitable for use.
Double Diamond is a model that is often used in the process of designing products and services, which consists of four stages: Discover.
Define.
Develop, and Deliver (British Design.
This framework allows researchers to explore the problem more deeply, define the problem more precisely, develop a more relevant solution, and deliver the solution.
Therefore, the use of the Double Diamond framework will be applied using the Software Development Life Cycle (SDLC).
https://ejournal.

php/jdbmi/index Planning, developing, testing, and releasing software can be done with the help of a structured Software Development Life Cycle or SDLC One of the SDLC methods used in this research is prototyping.
The iterative process of prototyping can enable developers and users to deeply understand system requirements through the creation of initial prototypes that are improved based on feedback (Debnath et al.
, 2.
This approach is particularly relevant in the development of information technology that is increasingly complex and dynamic according to user needs that can change over time.
This is especially important in the context of a company like CV SAS, which needs a website with specific features such as FAQs, and search features, to increase customer loyalty and competitiveness in the market.
In the context of this CV SAS website redevelopment, the use of SDLC Prototyping is in line with the need to create a solution that is user-friendly, informative, and functional.
User involvement during the development process through prototyping, companies can ensure that the resulting website is able to meet business needs and attract consumers more effectively (Tih et al.
, 2.
The purpose of this research is to redesign the CV SAS website to make it more informative and in accordance with the needs of the CEO and marketing staff of CV SAS as the requirement giver, obtained through This redesign was carried out using the Double Diamond framework approach and using the SDLC Prototyping method.
In addition to interviews, usability testing was also conducted in the form of a questionnaire addressed to regular customers of CV SAS.
This test aims to support and strengthen the findings from the interview results, by providing numerical evidence that the redesigned website has met the usability aspects objectively.
METHODS

Descriptive qualitative research is a technique for describing or interpreting collected data with consideration and sensitivity to various potential aspects being studied at present, thereby obtaining a general picture that encompasses every aspect of the actual situation (Akhmad, 2.
The data collection techniques used in this study fall under the category of primary data, as the data was obtained directly from the main sources through observation of the research object, namely the old website, interviews with internal company personnel, and the distribution of questionnaires to regular customers of CV Sentosa Abadi Steel.
The instruments used in this study included interview guides, wireframe prototypes and mockups created using Figma, and a Likert scalebased usability testing questionnaire that referred to Nielsen's five indicators, namely: Learnability.
Efficiency.
Memorability.
Error, and Satisfaction.
The research was conducted at the CV Sentosa Abadi Steel office in Sidoarjo.
The research subjects consisted of the CEO and marketing staff as system requirement providers, as well as five regular customers as end users involved in the usability testing.
The development process began with needs analysis, initial design creation, prototype development, design validation, and system implementation using the WordPress platform.
The final website was tested using usability testing methods to ensure that the system met the aspects of ease of use and user satisfaction.
RESULT AND DISCUSSION
Application of the Double Diamond Method in the Website Redesign Process of CV Sentosa Abadi Steel Discover The Discover stage is the initial stage in the redesign process of the CV Sentosa Abadi Steel website, which focuses on identifying problems and user needs.
This stage is important as it determines the problems in a system that is running based on user opinions (Gustafsson, 2.
The researcher used a combination of direct observation of the old website and in-depth interviews with the CEO and marketing staff of CV.
Sentosa Abadi Steel.
The CV.
Sentosa Abadi Steel website previously only had four main navigation menus, namely AuHome,Ay AuNews,Ay AuProducts,Ay and AuContact,Ay without a search feature or Frequently Asked Questions (FAQ) section to https://ejournal.

php/jdbmi/index help users find information about the company or its products.
In addition, several major issues were identified: .
Navigation on the website is suboptimal, making it difficult for users to find product information .
The website's appearance is unattractive and unresponsive, reducing user comfort when using the website.
Product information is and .
There are no FAQ and Search features, which are essential for users seeking specific information.
The findings in the Discover stage indicate that the old website does not meet the principles of good usability, particularly in terms of learnability, efficiency, and satisfaction.
In creating a website with ideal usability that meets user needs, there are five main components that must be fulfilled, namely Learnability.
Efficiency.
Memorability.
Errors, and Satisfaction (R.
Akbar & Mukhtar, 2.
These findings form the basis for defining system requirements in the Define phase, with the primary objective of enhancing user experience and the effectiveness of information delivery on the CV.
Sentosa Abadi Steel website.
Define The information collected during the discovery phase is then analyzed and narrowed down to the core issues that will form the basis for the development of subsequent design solutions (Farhantama & Mardhia.
From the findings of the discover stage, it was concluded that the main problem lies in the limited features and lack of effective navigation structure, which makes it difficult for users to find product information According to Fithri et al .
, an unattractive and unresponsive interface design, coupled with inconsistent display, can affect the quality of the user experience.
The elements contained in the website must be able to provide comfort to users when interacting with the website that has been created (Garrett, 2.
In addition, the product content displayed is incomplete and important features such as Search and FAQ are not yet These features can help users find specific information quickly(M.
Akbar et al.
, 2.
Based on these findings, several tools were employed to define the system requirements more clearly, including User Persona.

User Persona One of the results of this analysis process is the creation of user personas, which are fictional representations that describe the characteristics, behaviors, needs, and goals of the end users of the designed User personas serve as a tool for gaining a deeper understanding of users, while also providing a basis for design decisions so that the results of the design are more focused and on target.
According to Rian et al .
, user personas assist in the design development process by directing the designer's focus toward the needs of the target users, ensuring that the information and messages conveyed through the system are more relevant and efficient.

Customer Journey Map In this section, the customer journey mapping is based on user experience when using the old CV Sentosa Abadi Steel website.
The mapping covers five main stages, namely Awareness.
Exploration.
Consideration.
Decision, and Action.
According to Wibowo et al .
, customer journey mapping can help the design team understand the user experience comprehensively, including the emotional and functional barriers they are experiencing in each interaction process.
From the results of this mapping, it can be concluded that there are still several key issues that need to be addressed in the redesign process, such as website visibility in the search feature, ease of navigation, completeness of product information, effectiveness of the contact form, and post-order communication system.
Figure 4.
Priority Matrix According to Pugh .
, the Priority Metrix technique can help design teams prioritize features by considering their value and the available Additionally, this opinion aligns with the findings of del Sagrado & del yAguila .
, which indicate that integrating the MoSCoW method into a priority framework based on analysis will result in a more structured matrix, enabling efficient filtering of primary requirements.
The Quick Wins Quadrant shows that features that have a big impact and are easy to develop should be the top priority in this development.
