Digital Management of Micro, Small and Medium Enterprises (MSME) Activities Based on the Unified Approach

Purpose: Micro, Small, and Medium Enterprises (MSME) is an important part of today's Indonesian economy. The times have allowed many people to do their own business. Along with the many existing businesses, many business actors are marketing for the sustainability of their business. A web-based information system that can accommodate information about Micro, Small, and Medium Enterprises management is one of the main needs for MSME actors themselves. Methods/Study design/approach: In addition, the public can use this web-based information system to obtain detailed information on MSME and MSME products through the web. Making the web using the PHP programming language where the approach taken in the design is the Unified Approach used as a method in object-based system development. Result/Findings: From the final results of this study, it can be concluded that the web-based MSME Activity Management Information System can help mass marketing of MSME players and help related agencies to find out the development of existing MSME. Novelty/Originality/Value: The website was built can help and accelerate the marketing process for existing MSMEs and can be used as a medium of communication between MSMEs and visitors.


INTRODUCTION
Micro, Small and Medium Enterprises (MSMEs) are one of the fields that significantly contribute to spurring Indonesia's economic growth. Although MSMEs are always identified with businesses that start from limited capital or resources (such as labor, machinery and others), the development and growth of MSMEs from year to year shows a fairly good increase. This is because the absorption of MSMEs to the workforce is very large and close to the small people. It is estimated that from 2014 to 2016 the number of MSMEs reached more than 57,900,000 units. In 2017 the number of MSMEs is estimated to grow to more than 59,000,000 units [1].
Even though it has a strategic role, developing an MSME is not easy, especially in the marketing process. This is because marketing will encourage productivity and business growth [2]. Suppose the marketing process is carried out effectively. In that case, it will attract consumers to come and buy a marketed product, so that the expected benefits can be realized properly, and vice versa. One of the efforts to improve marketing quality is to improve the management of information systems and technology. Because by using technology and good information systems, people can manage their business well.
In Regional Regulation Number 23 of 2009 concerning MSME, article 4 paragraph (1): MSME Management Regulatory Policies, some of which are: point (f) facilitates the use of data banks and business information networks; and point (g) providing and disseminating information about the market, sources of guarantee financing, technology, design and quality. Referring to the Regional Regulation, it is clear that the central and local governments have the same obligation to empower, foster and develop MSMEs in their respective regions.
Based on the description above, a medium is needed to manage MSMEs, creating a web-based information system. By taking the case in Sawahlunto City where MSMEs in the Sawahlunto area still do not have a good management information system, an administrative system still managed manually makes the existing MSMEs only known by the people around the area. However, if an MSME has a good information system, it will impact the progress of the MSME itself and increase regional income.
Using the Unified Approach method, an object-oriented development methodology that combines existing processes and methodologies using the Unified Modeling Language (UML) as the modeling standard [3], will make this system development activity easier. Several previous studies have also carried out many system development activities with the same method in web development, including the Web for Complaints for Victims of Violence against Women and Children [4] and the Web-Based Integrated Disaster Response Management Information System [5]. From the results of previous research that discusses efforts to develop MSMEs in facing regional and global markets, it can be proven that the Unified Approach is very appropriate to be used as a method of current system development. The activities to help MSME players be more competitive by utilizing information technology.

METHODS
In this research activity, the method used is the Unified Approach (UA), then the steps taken are [6]: 1. The UA analysis stage consists of: a) Actor Identification, the stage of analyzing actors who interact with the system. b) Use Case Identification Use Case Diagrams are used to understand and know what functions are contained in a system and who can use these functions [7

] and c) Build a Use Case d) Building a Business Process Model
Business Process is a sequence of activities carried out by actors in the system to perform specific tasks to achieve certain goals. In this case, the UML diagram used is an Activity Diagram [8].   Figure 1, the proposed use case diagram can be explained as follows: a. There is 1 system that covers all activities of the information system for managing MSME activities. b. There are 4 actors who carry out activities, including: admin, MSME actors, community and leaders. c. There are 14 use cases carried out by actors, including: login: include username and password. home: MSME menu, product menu, news menu, list menu, MSME report, product report, MSME activity log report and logout.

Sequence Diagram
Sequence diagrams describe in detail the sequence of processes carried out in the system to achieve the objectives of the use case [10]. 1) Admin Login Sequence Diagram Based on Figure 3. The proposed sequence diagram of the MSME list: a. There is 1 actor, namely admin. b. There are 4 lifelines: the MSME information system, the MSME registration menu, data on MSME players, and a database. c. There are 5 messages.  Figure 4, the proposed MSME data sequence diagram: a.
