Science and technology serve as the foundation for opening a wider information network and conveying various types of From the results of interviews with several businesses that were categorized as Small and Medium Enterprises, customers were not well managed. Customers are only maintained once a year. If there is good information about a product or a change in price they don't get it. Apart from this, many small and medium enterprises are still manual or have not used the system. From the surveys and interviews conducted, they really need a system. The system is expected to assist in managing customers. There are a lot of as Small and Medium Enterprise in the field of selling the Nine Staples and this is an opportunity for technological The process of making and implementing ECommerce in as Small and Medium Enterprise is designed based on data processing of sales of basic necessities in the System testing adapts the User Acceptance Test (UAT) model, this is a testing process by users that aims to produce documents that can be used as evidence that the system created can be accepted by users using the questionnaire method. LITERATURES REVIEW According to . Regulation of the Minister of Finance number 210/PMK/010/2018 concerning Taxation Treatment of Trading Transactions through Electronic Systems, it explains that an electronic platform is a container in the form of applications, websites, and / or other content services internet-based which is used for transactions and/or trade facilitation through an electronic system . -commerc. , while the electronic market . is a means of transactions aimed at conducting electronic trading business activities. Online transaction processing systems have a very strategic role in commercial trade. Many companies use the internet, extranets, and other networks to bond with customers and suppliers using electronic means. They use online transaction processing (OLTP). The system can process transactions immediately, can help companies provide great service to customers and other trading partners. The emergence of E-Commerce is largely built by several factors, including: . Evolution of the existence of computers and hardware and software, . Development of computer networks and the internet, . the digital era will change people's mindsets and lifestyles . According to Law Number 20 of 2008, the definition of as Small and Medium Enterprise . Micro business is a productive business owned by an individual and/or an individual business entity that meets the criteria for a micro business. Small business is a productive economic business that stands alone. This business is carried out by business entities or The business is not a subsidiary and not a branch of a company that is owned, controlled, or is a direct or indirect part of a medium or large Medium enterprises are productive economic enterprises that stand alone. This business is carried out by individuals or business entities and is not a subsidiary or branch that is owned. This business is also not controlled or is a part, either directly or indirectly, of small or large businesses with total net assets or annual sales proceeds as stipulated in the Law.

Tests can define a set of input conditions, and perform tests on the function specifications of a program. Black-box testing is carried out to find errors for each function of the program. Black-box testing is also designed to validate functional requirements without needing to know the internal workings of a program. User Acceptance Testing User Acceptance Testing is software testing that is used to find out whether there are defects or defects in the application or software being developed. II. FRAMEWORK The research conceptual framework : Figure 1. Research Concept Framework The above conceptual framework can be explained as follows: The researcher conducted a technology study in terms of various aspects of the current problems, and reviewed the institutional and information technology System development method Rapid Application Development (RAD) is used to analyze and design software with the Unified Model Language. Coding using the PHP programming language and MySQL database, and testing the system using Black-Box Testing. The application display is built so that users can input data to be stored into the MySQL database and one time the data can be displayed in the form of information with a more user friendly visual appearance and good user This application can be accessed by system users with user level Tests carried out then conclude whether the system has met the requirements to pass the test based on the User Acceptance Testing method software. METHODS Based on the research objectives included in Development research is a method TUGIMAN / J OURNAL TECH-E - VOL. NO. used to produce a product and test its Research and development methods have been frequently used in the field of information technology . Methods of data collection by means of: interviews, observation, literature study, and User Acceptance Testing is software testing that is used to find out whether there are defects or defects in the application or software being developed. User Acceptance Test is a testing process carried out by the user with the output of a test result document that can be used as evidence that the software created has been accepted by the user. In addition, the software that is made also meets the needs requested by customers or users. According to . , testing in software engineering is a series of stages that are implemented sequentially. This test is to determine the quality of the software that is in the hypothesis. The criteria for selecting the characteristics of respondents as research samples for testing this software are based on the level of users in accessing the system. Testing data processing using tools in the form of descriptive statistical analysis. The data collected consists of a description of the facts that are processed into data. From this data then analyzed in order to obtain a Descriptive statistics are a type of statistics used to analyze data by describing or describing the data that has been collected as is without making generalized conclusions or generalizations. The development strategy or object-oriented system development is to organize and integrate a software system as a collection of objects containing data and operations that are enforced in a way that the system is built through a systematic object approach. Sequence diagram can describe objects in a use case and a massage that runs in a use Sequence diagrams also describe objects and their relationships including the logical chronology of changes after receiving a message. The system development method uses Rapid Application Development (RAD). This method is an option from the System Development Life Cycle (SDLC). Information systems development method with a relatively short time. The main objective of the RAD method is to provide a system that can meet user expectations. fact, it often occurs when the development of a system does not involve the system users According to . Rapid Application Development is an incremental model of the software development process, especially because the time required is relatively short. The team must be able to understand the software requirements and must be limited in scope so that the team can complete the software creation in a short time. The RAD model is implemented by dividing the development team into teams. All teams work on several components, the work of each team can be done in parallel. Business Modeling Modeling is done by creating a workflow that has been running, then modeling it using activity diagrams and use case The needs include system users, both business owners and customers, so that users' information needs can be Besides that, it can also make it easier to create programs. Data Modeling Modeling the data needed by the system, namely: user data, goods, customers, suppliers, purchases, sales, inventory, and reporting data. Process Modeling Implement defined business functions related to defining data. Processing images are created to add, modify, delete or retrieve data objects. Modeling using sequence diagram tools. Making Applications Implementing process and data modeling into a program. In this process, it is created using the PHP programming Testing and replacement TUGIMAN / J OURNAL TECH-E - VOL. NO.
