I. INTRODUCTION
Improvements in human resources have made rapid developments in technology and information. The development of technology and information accompanied by the development of the internet mutually support each other so as to create an information technology concept. Technological developments are currently growing rapidly, almost all aspects of human activity and life depend on technology to facilitate the activities carried out. Whereas in the business sector, technological developments play an important role and have a very significant impact on the systems that work in this business sector, especially in sales, data processing and improving services provided to customers [1]. Today, there are still many companies or trading businesses that have not used technology, causing limitations in the marketing and sales of the company's own products, because marketing does not cover many areas and is limited. One way to increase the area of marketing is by using internet technology which can cover many areas. At UD. Aneka Plastik, the absence of online marketing makes it difficult for buyers to see directly the available plastic products apart from having to come to UD. Aneka Plastics, and because they haven't used online marketing marketing carried out by UD. Aneka Plastik does not yet cover a large enough area.
With internet technology, people from many areas can connect easily and quickly. The Internet itself is a collection of global networks that are connected to each other for the means of disseminating information with a set of protocols. The internet is also a network between people and information so that it is very possible for the internet to be used as a medium for doing business and running a business. The use of internet technology is not only limited to the utilization and dissemination of information between people, but can also be used as a medium or means to carry out a trade transaction called e-commerce. E-commerce is the distribution, buying, selling, marketing of goods and services through electronic systems such as the internet or television, www, or electronic data exchange networks, automated inventory management systems, and automated data collection systems. Based on the references obtained, E-Commerce is electronic commerce, is a collection of technologies and businesses that connect companies or individuals as consumers to carry out electronic transactions, exchange of goods, and exchange of information on the internet or television, or other computer networks [2].
UAT is one of the most innovative methodologies to prevent IT project failures. The UAT process begins by providing documentation of business requirements, then continues with business processes (workflows) or scenarios and finally tests using data. Effectiveness in testing is needed in the development of an application or information system so that the product can arrive at the user on time and according to the user's needs. Tests carried out on the built system are divided into two mechanism tests, namely alpha testing using the black box method and beta testing using a Likert scale. Black box testing is focused on system testing activities that are built to see how far each function in the application has been running correctly, as expected and free of errors. Apart from testing the application from a functional point of view, system testing is also carried out by users who will take advantage of the application. Beta testing to determine acceptance of the use of the application is carried out with a questionnaire to obtain conclusions about the acceptance of the use of the application from the user's side [3]. Based on the background contained above, a research was carried out "Analysis And Design Of Online Based Plastic Sales Information System Using User Acceptance Testing Method".

Plastics
The definition of a plastic is a type of macromolecule that is formed by a polymerization process. Polymerization is the process of combining several simple molecules (monomers) through chemical processes to become large molecules (polymers or macromolecules) [4].

User Acceptance Testing
UAT is one of the most innovative methodologies to prevent IT project failures [3].

E-Commerce
E-commerce is the distribution, purchase, sale, marketing of goods and services through electronic systems such as the internet or television, www, or electronic data exchange networks, automated inventory management systems, and automated data collection systems [2].

Sales
Sales is a system of the company's main activities for trading goods and services that the company produces [5].

Databases
A database is a collection of connected data (interrelated data) that are stored together on a medium, without looking at each other or without the need for a data framework (controlled redundancy) in a certain way so that it is easy to used or reproduced [6].

Hypertext Preprocessor
PHP is a programming language for creating website-based applications, PHP is also often known as a hypertext preprocessor which is a high-level scripting language that is installed in HTML documents [7].

Frameworks
In simple terms, it can be explained that a framework is a collection of functions (libraries) so that a programmer no longer needs to create functions from scratch and is usually called a collection of libraries [8].

MySQL

XAMPP
XAMPP is an open source software which is the development of LAMP (Linux, Apache, MySQL, PHP and Perl) [12].

UML (Unfield Modeling Language)
UML stands for (unified modeling language) which means standard modeling language. UML has syntax and semantics [13].

Black Box Testing
Black box testing is a type of testing that treats software whose internal performance is unknown. So that the testers view the software as like a "Black Box" which is not important to see the contents, but enough to be recognized by the testing process on the outside [14].  The login page is the page to enter the main page by entering the user's email and password. The user's main page is the initial page when the user successfully logs in. The product list page is a page for changing and adding products. The shop page is a page for shopping for the product you want.

System Testing Using the User Acceptance Testing (UAT) Method
Testing was carried out by giving 10 questions to 10 respondents to find out responses to the system to be implemented. Answers can be selected from the following levels:   Is this application easy to use?
Is the application useful for users? 8 Does this application suit your needs? 5 4 1 0 0 50% 40% 10% 0% 0% 5 Is the application comfortable to use? 7 Is the use of the menu or menu application features easy to use?
Is the menu in the application complete enough? 7 2 1 0 0 70% 20% 10% 0% 0% 8 Are the results displayed by the application according to your needs / desires?
Is the information provided by the application easy to understand?
Overall is the use of this application satisfactory? 8 0 1 0 1 80% 0% 10% 0% 10% Is the application easy to operate? Is the use of the menu or menu application features easy to use?   From the data above, it can be concluded that the sales information system for online-based plastic sales using the User Acceptance Testing method is in accordance with user needs.
