Understand and complete the following Case Study:

Indonesia is a country that is famous for having abundant natural wealth such as mineral resources, gas, oil and biodiversity. For The Indonesian government encourages maximizing the use of natural resources development of Micro, Small and Medium Enterprises $($MSMEs$)$ as one solution for increasing the use of natural resources and improving the social economy. Based on a press release from the Coordinating Ministry for Economic Affairs of the Republic Indonesia, the Coordinating Minister for the Economy explained that the contribution of MSMEs reaches the range $61\%$ of National GDP and absorbs $97\%$ of the total workforce. $($Ministry Coordinator for Economic Affairs of the Republic of Indonesia, $2022)$

In terms of competitiveness and sustainability, in general, MSMEs have deep weaknesses availability of stock of goods and number of employees. Generally there is no available stock of goods too big considering that MSMEs have low capital. Generally, MSMEs rely on turnover from stock of goods with a small inventory of goods and combined with a small number of employees, namely around $2$ to $100$ people. This matter Of course, the process of monitoring stock data is very important. If it happens mistakes, out of stock will cause loss in sales in the business $($Handojo$,$ Wibisono, Noertjahyana, & Octavia, $2020).$

Therefore, inventory management on stock items needs to be carried out to check

the difference between the quantity of goods in the warehouse and the recorded quantity. While management assets aims to control assets owned by the business such as furniture, computers, equipment and business supplies. Inventory management activities in MSME companies can take a long time depending on the number of goods and assets and require conditions where there are no transactions or it is not busy, so if there are Items that are damaged or lost cannot be identified quickly and are found the problem of the possibility of recording errors being made if the goods are recorded quite a lot $($Handojo$,$ Wibisono, Noertjahyana, & Octavia, $2020).$

One of the sectors in MSMEs is the trade sector. The focus of this MSME sector is on sale of new and used goods. The MSME sector has an important role in economy and has a significant influence on economic growth region. Trading business activities involve buying, storing, and selling. For storage activities, it is important to have stock of merchandise and facilities warehousing in order to optimize the use of working capital in inventory $($Bank Indonesia, $2015).$

Waterfall methodology is a software development methodology. The waterfall method uses a systematic approach, and has sequential stages in depth

development starts from communication, planning, modeling, construction, and finally deployment. One of the advantages of the waterfall method for application development is quality The resulting system will be good because the implementation is carried out in stages. Will but one of the disadvantages is that it takes longer. But with Therefore, the waterfall method is suitable for new system development projects and projects which has few requirements and does not change $($Wahid$,2020).$

Based on the information previously explained, a search for sources was carried out owns an MSME business in the trade sector to assist in management aspects

inventory. From the results of interactions through interviews with sources, they revealed Difficulty in managing inventory effectively and efficiently. So the idea emerged to develop an Android$-$based mobile application that allows owners

MSMEs can manage inventory quickly and easily with the aim of creating applications Android$-$based mobile inventory management that can be accessed at any time, Creating New recording method to minimize the risk of manual notes being damaged or lost and increasing supervision of incoming and outgoing goods.

With this in mind, your task is to:

$1.$ Make a Use Case Diagram according to the needs in making the application.

$2.$ Make $2$ Activity Diagrams based on the Use Cases created.

$3.$ Create a Software Architecture for the application to be created.

$4.$Identify risks based on the problems above when creating the application and

application implementation.
