INTRODUCTION
With the advancement of technology nowadays, any information that we want to learn can be obtained quickly. Apart from making it easier to get information, technological developments also help us live our daily lives with the emergence of a wide selection of existing applications, be they desktop applications, online applications, and also mobile applications. [1]. Existing applications will help in various fields such as communication, finance, transportation, and others. Smartphones are one of the most popular ways for people to keep up with technological advancements and receive timely information. This is due to the nature of smartphones, which can be used at any time and in any location, as well as their small size and ability to be accessed at any time [2].
Android-based smartphones have evolved into a single open-source platform where users may create and deploy applications [3]. Applications on Android are only for entertainment. Nevertheless, not all applications are classified as mere entertainment; instead, applications might be classified as business strategies. Almost all business owners are now using apps to help them run their businesses, allowing them to work more efficiently and effectively [4]. To sell and buy products, you must have an internet connection. Due to the fact that manual sales processes are more likely to result in significant losses, it is necessary to develop software that may help with the sales process [5]. Android is the most widely used smartphone operating system in the general population, particularly in Indonesia [6]. One of the advantages of Android-based smartphones is the ability of the Android operating system to be updated or upgraded from time to time [7].
Queuing is a phenomenon that occurs in everyday life and occurs in public service facilities. A queue will occur if the number of customers who are served exceeds the capacity of the available services. Queues are often found in other public facilities, including car washes. Increased two-wheeled and four-wheeled vehicles results in increased demand for mobile or motor service. This alone has the potential to improve business performance by improving customer service, allowing customers to spend less time waiting and having more flexibility in the process of moving their belongings [8]. Competition in car wash services is currently very competitive due to the large number or proliferation of motorized vehicle users in Indonesia. Because of this, every business must provide a better information system to the public, particularly in the case of mobile washing queues. Yet, many businesses that provide queuing information rely on manual or word-to-mouth transmission [9]. To prevent a business from failing, it is necessary to conduct research. The recipe is to continue to do and increase sales turnover or number of customers because the goal can be achieved only by increasing sales turnover or number of customers. Increased sales turnover will, in turn, increase the profit of the company. Increasing profits is important for businesses that want to continue operating and expanding in orders to improve their lives. The profit that is desired must be consistent with the goals that have been established at each time [10]. Point of Sale (POS) is a sales-oriented activity and a system that helps transactions. The use of POS has increased productivity by allowing for faster processing of client orders, faster data entry, and faster transaction processing [11]. Manualprocessing systems frequently experience problems with data capture and storage [12]. Making reports that are complicated because they have to be made by recapitulating the data in the transaction book, the transaction process is long because transactions must be calculated manually [13].
The following are the symptoms of a vehicle wash queue: long waiting time: When there are a lot of people who want to know what's going on, the waiting time might get quite long. This can result in better health for those who need to rest in a hot environment. Inability to handle large volumes: If a car wash business does not have adequate staff or facilities to handle large volumes, the car wash queues will be long. This might result in a loss of customers and a higher rate of pay. Operational issues: If there are operational issues, such as a faulty vehicle engine or a slow-moving staff, this might slow down the vehicle process and lengthen the time it takes. Queue management: If a business does not have an effective queue management system, such as prioritizing customers who pay on time or using a queue number system, the car wash queue may become stale and difficult to manage. To address this issue, the mobile washing business can expand its capabilities and staff by utilizing technology to increase queues and increase staff training to improve the efficiency of the mobile washing process.
Based on the above problems, the author wishes to provide a solution by leveraging the advancement of smartphone technology. The M-Wash application can make it easier for consumers (especially for new people who have just joined a community) to find and find vehicle washes around them, especially those at PT. Apart from that, the M-Wash app has a feature that allows users to perform vehicle cleaning services from anywhere, including their homes. And consumers can choose the processing time and price attached to it. Furthermore, for those who provide vehicle wash services, this application may help to increase profits while also making it easier to be recognized by the public and businesses.
To continue this research, several previous studies have been carried out, using various methods and platforms to create an application called M-Wash which is used as a comparison tool, starting from the severity of excess to the type of platform used as a comparison. references and references to do previous research. Website-Based Mobile Laundry Queuing System Using CRM and Apriade UML Implementation [9] Application [19] and Application for ordering gallon water online with gallon delivery features for Android [20] Due to the existence of ongoing research, the primary goal of this research is to develop effective and efficient applications for vehicle wash, as well as features that are required in vehicle wash applications to assist users in using safe and efficient vehicle wash services.
The primary goal of developing a vehicle wash application is to make it easier for users to manage their vehicles in a more efficient and practical manner. Some other goals of the vehicle wash application include: Speed up ordering -With the vehicle wash application, customers can order vehicle washing services online without having to come directly to the laundry, Vehicle washing applications can provide a wide selection of vehicle washing services to suit customer needs, such as car washing, motorcycle washing, and others, Increase service quality -By utilizing application technology, users may provide feedback and information about service quality, allowing business owners to make informed decisions about how to improve service quality, and The vehicle wash application can assist business owners in optimizing the management of available time and resources, such as setting vehicle wash schedules, cleaning stock management, and more.
