I. INTRODUCTION
Trading Business of Ballet Shoes Home Industry is SMEs engaged in the production and sale of shoes. It is located at Jl. Sersan Mustajab, Daleman Hamlet, Japan Village, Sooko, Mojokerto.
Shoe SMEs only rely on customers from within the city. Media promotion is only in the form of brochures and direct offers. Today's business competition is very tight. So Trading Business of Home Industry of Ballet Shoes is demanded to be more advanced. Not only getting customers in the city but thoroughly outside the city. TB. Ballet Shoes Home Industry Shoes has a problem with promotional media and does not yet have an item catalog. The results in the current turnover being less than the maximum. Profit is currently only obtained from customers within the city.
Media campaigns that are often used are brochures, Facebook, and direct offers. The need for promotional media is significant to achieve success in business competition [1]. However, in reality, it is still less useful because it only relies on social media. One way that can be used is an online sales information system [2] [3]. The online sales information system is a media of buying and selling transactions conducted online that connect companies and consumers electronically [4]. Based on the above problems, the Home Industry Ballet Shoes Trade Business can utilize the online sales information system.
The online sales information system is expected to help smooth business competition. This media is more effective in editing, storing, deleting, searching for product data. This media is designed to make product information to customers more comfortable to find. This online sales information system is designed with a simple and attractive interface so that users can use it more efficiently [5] [6].

II. RESEARCH METHOD
The method applied in this research is the observation for useful data collection and studying the system by observing the research object [7] directly. Then the interview is a data collection technique by a direct question and answers about the data needed from the problem to be raised.
Literature study by collecting data by reading library books, which is support in obtaining data to complete the preparation of reports relating to the issues discussed [8]. For system development, the method used by the author is the incremental method, which is a system development model Test which are the testing stages in this model [9] [10] [11]. The incremental steps in Figure 1 are carried out sequentially, where each part that has finished testing is sent to the user for immediate use. In the incremental model, the first three stages must be completed first before building each increment [9] [10] [11].

System analysis is carried out to obtain information about the system, analyze the data in the order related to online sales activities. Information collected is mainly about the advantages and disadvantages of the system [12]. Design is a new system design based on data that has been raised in the previous stage by designing software including Context Diagrams, Data Flow Diagrams (DFD), Entity Relationship Diagrams (ERD), Data Dictionary (Data Dictionary), File Structure, Menu Structure, Designing inputs and Output designs. Coding is an activity to create a program or implement the results of an application program design, which includes data conversion into a new system and periodic system conversion, including in terms of maintaining the system itself [13] [14]. Testing to tighten the program that has been made, whether it is correct or not, is appropriate or has not been verified manually if the testing is accurate, then the program may be used. Maintenance is an activity to maintain the application program that has been made, so that the integrity of the program can be managed, such as data validation, updating data, and protecting the program from virus attacks, unauthorized people who can damage the program [15].
Analysis and design of the system require systematic steps to get a proper application and following the purpose and purpose. The initial stage of the study is to analyze system requirements ranging from user needs, non-functional needs, and functional needs [12]. As for the application design stage, namely database design, and interface design [15] [16] [17]. Based on previous research and theories that support it, then the outline of this system can be arranged in the form of context diagrams such as Figure 2. This diagram illustrates the interaction of the system with external entities, namely admin, customers, and owners. Admin has full rights to the system and data management, such as insert, update, and delete. While the customer has the right to goods or products in this case in the form of shoes, shoe models, shoe colors and prices for each shoe and for the owner to get a report on the order of goods, stock of products, orders and income [13] [14].

III. FINDING AND DISCUSSION
After system planning, the next step is testing the system that is made. For testing the system, several support systems are needed, including PCs with Windows 7 32 bit OS or later versions, Xampp version 1.7.3., My SQL, Mozilla browser, or Google Chrome. Implementation of the interface is done with every page that is made both the front view that is built for customers to log in and shop and the back view that is used by the admin for the input and transaction processes. The following are some of the interface displays that have been implemented. The front display system interface consists of item menus, shopping carts for customers, and the login and register process. To be able to process transactions, customers must first register for membership. The initial menu implementation can be described, as shown in Figure 7.
The frontend is the main menu display of the system displayed on the website. To access the main menu, the user or customer must register first so they can process the transaction. The main menu implementation can be described, as shown in Figure 6. Shopping cart menu interface is useful to keep a list of products ordered by customers. The implementation of the shopping basket menu can be described, as shown in Figure 8.

The payment confirmation form interface is used for the user or customer to confirm payment by transfer. If you have approved, the admin will process the order to send the goods. The implementation of payment confirmation can be described, as shown in Figure 9. The order detail page interface is used for users or customers to view data on transactions that have been carried out, transaction status, as well as shipping information. The implementation of order details can be described, as shown in Figure 10.  The goods return page interface is a page to process the product return from the customer.
The following figure 13 displays the results of the implementation of the item return page.

Usability Testing is a way to evaluate a software product by testing it with prospective users, namely the SMEs of shoe trading businesses with male or female gender, aged 23-40 years who are familiar with the use of computers. In this test, the software to be tested is an online shoe trading information system. In usability testing, only use completion rate as success metrics like Table 1. To find out which pages the user has difficulty using the design that has been made. The pages or software modules that will be tested in 5 stages, with five users [18]. From the test results, it appears that user 1 to user 5 has the ease of carrying out every step in the Usability Testing model. It appears that user 4 when running the stage of the product promotion of product input process does not experience difficulties including user five also does not experience problems at the time of initial login to the system, but overall almost all users have no difficulty in running every step available at completion rate.
