## ABSTRACT

This study presents a novel approach to improve the efficacy, efficiency, user engagement, and security in Wi-Fi voucher notification systems. The proposed method leverages the capabilities of Telegram API bot notifications to create an automated, real-time system for Wi-Fi voucher distribution. Notifications are dispatched rapidly and effectively, reducing human intervention and potential delivery issues. The system enhances user engagement by allowing interaction with the bot through predefined commands or responses. This interactive feature enables users to access information about Wi-Fi vouchers, modify their notification preferences, and perform other Wi-Fi-related tasks. To develop this system, the research methodology employed six stages: Preparation, Planning, Design, Implementation, Operation, and Optimization. This resulted in a notification system that could monitor various aspects of the network and inform network managers in real-time. Key features include the purchase of Internet vouchers, active user monitoring, tracking of all users, tracking of multiple subscribers connected to the integrated hotspot network, and monitoring of upload and download traffic on the hotspot network. This research contributes to the field of wireless access networks by demonstrating an effective use of Telegram API bot notifications, thereby setting a precedent for their application in similar scenarios.

## 1. INTRODUCTION

Telegram bots have recently gained traction as a notable mode of user communication and interaction [1]. Their utility ranges from various purposes, with a notable application being the provision of user notifications [2, 3]. An intriguing avenue of research is the implementation of Telegram bots for the purpose of Wi-Fi voucher notifications, given the widespread usage of this platform [4-6].

Traditional methods of notification delivery, such as Short Message Service (SMS) or electronic mail (email), pose a set of limitations [7]. Extra costs associated with SMS and the potential for emails to be relegated to spam folders serve as significant impediments [8]. As such, this research seeks to investigate the viability of Telegram bots as a more efficient and effective alternative for disseminating Wi-Fi voucher notifications [9].

Leveraging Telegram bot notifications [10] allows for the automation of the notification process, thereby enhancing the flexibility in structuring and customizing outgoing messages [11]. This investigation, therefore, aims to delve into this potential and assess the efficiency and utility of an automated notification system employing Telegram bots [12].

User responsiveness tends to increase when notifications are delivered via platforms in active use, such as instant messaging applications [13]. Hence, the utilization of Telegram bots in this study is expected to boost user

engagement by delivering Wi-Fi voucher notifications through extensively used and interactive platforms [14, 15].

In the realm of Wi-Fi voucher notification systems, user security and privacy emerge as critical considerations [16]. Telegram bots offer a layer of encryption and security, ensuring the confidentiality of transmitted information [17, 18]. Accordingly, this study aims to explore the potential security benefits and privacy enhancements offered by Telegram bots in the context of Wi-Fi voucher notification delivery [19].

The research questions guiding this project are: How can a Wi-Fi voucher notification system be implemented using Telegram bot notifications, and how does the use of such notifications influence the effectiveness, efficiency, user engagement, and security of the Wi-Fi voucher notification system [20, 21]? The objective of this research is to implement a Wi-Fi voucher notification system using Telegram bot notifications and enhance effectiveness, efficiency, user engagement, and security in notifying users about the availability of Wi-Fi vouchers [22].

## 2. RESEARCH METHODS

PPDIOO is a Cisco network service policy or, more generally, a Cisco method for assessing networks that is intended to identify the beginning of a network failure [23].
PPDIOO stands for Prepare, Plan, Design, Implement, Operate, and Optimize. The PPDIOO paradigm, which stands for Prepare, Plan, Design, Implement, Operate, and Optimize, is a troubleshooting approach that Cisco defines [24]. Consequently, in this study, hotspot network monitoring is designed using Telegram notifications. Figure 1 illustrates the steps taken utilizing this type of study:

### 3.2 Plan

After the equipment in the prepare stage has been prepared, create an analysis of the system's workings that is transformed into a block diagram so that researchers may comprehend the system's design's flow or function.

According to Figure 2, the system starts working when a user connects to an SSID hotspot and displays the login page. If the user already has a voucher, they can enter it or scan a barcode. If they don't, they go to the voucher page and choose the sort of voucher they want. The client registers for a Telegram account on the CGR Bot by clicking the "buy" button, which

directs them to the Telegram application where they can access the CGR Bot. Then, after correctly filling out the base deposit to purchase the voucher, the customer can select and purchase a voucher in the deposit. Upon successful purchase, a barcode, voucher ID, and expiration date will be shown. The Administrator can then monitor the total Voucher account on the Wi-Fi network and can monitor clients who are currently using the CGR net Wi-Fi network after the client enters the Voucher id on the login page, successfully logs in, and receives a notification that the client has successfully logged in to the Telegram Bot.
<figure><img src="image_3.png" /><figcaption>Figure 2. How the system works</figcaption></figure>

## 3.3 Design

At this point, it has topology and network infrastructure that have been modified to fit the Cibanteng rt01/rw08 environment's Wi-Fi network infrastructure. The network system utilized in this research to explain and facilitate the idea of network topology is referred to as topology. Network topology is displayed in both high-level and low-level designs.

### 3.3.1 High Level Design Wi-Fi RT.RW Net

The High Level Design of the RT Wi-Fi network structure is shown in Figure 3. An Internet source from an ISP that is obtained using a modem and is identified as RW Net in the Cibanteng environment has an internet provider (IP) address of 192.168.x.x/24. When a client successfully logs in, the Telegram Bot notifies him via Ether 1 mikrotik, which is connected to the modem for setting DHCP Client has IP Address 192.168.x.x/24, gateway 192.168.x.x/24, Access Point is connected to mikrotik for hotspot lines for clients connected wirelessly, and internet provider (IP) Address dhcp with range 10.10.xx.x-xxx. The Dynamic Host Configuration Protocol (DHCP) server for the tp-link tlsf1008sd switch, which connects residential clients using Local Area Network (LAN) cables, is located at 192.168.xx.x-xxx. After a client successfully signs in, the Telegram Bot notifies them.

### 3.3.2 Low Level Design Wi-Fi RT. RW Net

Low Level Design discusses the RT Wi-Fi network's structural design in Figure 4. RW Net's IP address in the Cibanteng environment is 192.168.x.x/24, and it is used to identify internet traffic flow from Internet Service Provider (ISP). flow of traffic When a client successfully logs in, the Telegram Bot notifies him. Ether 1 mikrotik is connected to the modem for setting Dynamic Host Configuration Protocol (DHCP) Client has internet protocol (IP) Address 192.168.x.x/24, gateway 192.168.x.x/24, Access Point traffic flow is connected to mikrotik for hotspot lines for clients connected wirelessly has internet protocol (IP) Address dhcp with range 10.10.xx.x-xxx. A Dynamic Host Configuration Protocol (DHCP) server at 192.168.xx.x-xxx manages traffic flow from the Tp-Link Tlsf1008sd switch to home clients connecting via Local Area Network (LAN) cable. After a client successfully signs in, the Telegram Bot notifies them.

## 3.4 Implement

Monitoring the network and removing Telegram Bot API alerts are carried out during the implementation stage. This step of implementation is already finished.

### 3.4.1 Implement Mikrotik

In Figure 5 there is a port interface. Each computer network's capacity can be configured and shared by Mikrotik, and the bandwidth for international and domestic data traffic can be separated.

On the ether 1 port, namely Public Internet Interface/ISP-ether1.

On the ether 2 port, namely Interface LAN-ether2.

On the ether 3 port, namely Interface LAN-ether3 is for Mikrotik RouterBoard external access point

#### (a) Steps in Hotspot configuration

The first thing that needs to be done in order to configure a Mikrotik hotspot is to configure the Access Point on the local-master-hotspot before configuring the hotspot on the ether Access Point.

In Figure 6 Hotspot setup. Open in IP menu -> Hotspot -> Hotspot Setup.

Then click the Hotspot Setup button, the Hotspot wizard will guide us through the settings by displaying dialog boxes at each step.

In Figure 7 Hotspot Interface. Next we are asked to specify the interface where the hotspot will be activated. In this case, the hotspot is activated on the local-master-hotspot, which we have set as an Access Point (ap-bridge). Then click Next.

In Figure 8 DNS Name. The last step, specify the username and password to log into your hotspot network.

<figure><img src="image_7.png" /><figcaption>Figure 6. Hotspot setup</figcaption></figure>

<figure><img src="image_8.png" /><figcaption>Figure 7. Hotspot interface</figcaption></figure>

<figure><img src="image_9.png" /><figcaption>Figure 8. DNS name</figcaption></figure>
<figure><img src="image_10.png" /><figcaption>Figure 9. Local hotspot-master-hotspot configuration results</figcaption></figure>

<figure><img src="image_11.png" /><figcaption>Figure 10. User profile</figcaption></figure>

In Figure 9 Local Hotspot-Master-Hotspot Configuration Result. Next, we have finished configuring the hotspot profile settings.

(b) Configuration Create a User Voucher account and Hotspot login Password

In Figure 10 User Profile. Then, we provide each user a User Voucher account and a password. The secret is to open the IP menu, select Hotspot, choose User, and then enter the server name, password, and profile information. Like the following:

The following stage is to develop a User Profile and restrictions that will be offered to users through the menu: IP >> Hotspot >> User Profile >> add new, enter the name parameter, and adhere to the restrictions. The current rate limits are briefly explained as follows: Transfer to give quota-based limitations, download and upload to assess data speed, and uptime to establish internet access consumption caps.

### 3.4.2 Implementing The Application

**(a) BotFather Telegram**

We look for and invite @BotFather in the search column before configuring Telegram since it monitors user logins and lets us know when a user logs out and back in via the Telegram program can keep track of a user for 24 hours, therefore we can keep track of login and logout times. We build the boot using the name: /newBot, and after that, a description will display asking us to choose the name of the Bot that will be created automatically. In Figure 11 bot father this case, I'll create the Bot first as an example: CGR WI-FI Bot.

**(b) Fire Bot**

Developer which is a separate entry. Its main function is to help human users which is officially supported by Telegram.

* Get API Tokens

As this account has never been used before, I'll use its name, CGR WI-FI Bot, in Figure 12 API tokens here, and it will immediately function as shown in the figure below.

* Running Hotspot Scripts

Script hotspot. This Hotspot script will be able to send login and logout messages to the Wi-Fi hotspot that we got on the Telegram Bot token fire earlier, so next we will insert the script on the User Profile menu -> User hotspot (which we created before) -> Script.

* Mikrotik Script with Telegram Bot

Figure 13 shows a Mikrotik script and a Telegram bot. It goes without saying that you must have a web server and at least a basic understanding of PHP programming in order to develop a Telegram Bot that you can talk with [25]. If you don't have either of those things, however, the process can be very challenging [6]. In this article, we'll create a Telegram bot

that we can use to invite others to "chat" while also keeping an eye on the health of our Mikrotik by using the Scheduler system and system script capabilities [26].

<figure><img src="image_14.png" /><figcaption>Figure 13. Script with telegram bot</figcaption></figure>

## 3.5 Operate

The operating phase is an experiment in using the created Bot program [27]. The Monitoring system is used to test the Bot software so that each step can be seen.

### 3.5.1 Instructions via smartphone device

Here are the steps to use ie:

* Connect your smartphone to Wi-Fi using the SSID CGR Net Hotspot as the network name [28].

* When prompted, enter the username and password that the administrator has provided to the user on the hotspot login page. In Figure 14, if the client does not have a voucher code, choose the Voucher button.

Vouchers page in Figure. A voucher page will then open, allowing the customer to select a voucher before clicking the "purchase voucher" button [29, 30].

* Will open the Telegram program page, after which the user clicks the Telegram Bot's restart button to initiate a conversation.

* Shows a list of executable functions in Figure 15. To view a list of executable functions, the client then inputs the Telegram Bot /help function.

<figure><img src="image_15.png" /><figcaption>Figure 14. Vouchers page</figcaption></figure>
<figure><img src="image_16.png" /><figcaption>**Figure 15.** Displays a list of executable functions</figcaption></figure>

The client then enters information on the cgrBot / list page to register the client's User ID with the Admin on the Telegram Bot page.

The client then types on the /deposit page to ask the administrator for a balance deposit.

Once the amount has been successfully topped off, the customer can begin purchasing Vouchers.

Buy vouchers in Figure 16; client to select voucher from list below.

The client hits the Go to Login button in Figure 17 to return to the Wi-Fi Cgrnet login page after receiving a message from the Telegram Bot with the barcode, voucher id, and expiration date.

We then enter the Voucher code that was provided by the Telegram Bot in Figure 18 Login Page Hotspot.

When we succeed, the Telegram Bot we earlier constructed will receive an automatic notification that the hotspot account has signed in.

Once the user has finished using the hotspot account, it automatically logs out on its own and notifies the administrator via the Telegram app that the voucher has successfully logged out. A message from the Telegram Bot will then appear with the IP Address, mac Address, device, voucher package, time used, amount of quota, used quota, remaining quota, and expired information.

Figure 19: Total User On the Hotspot user page, enter the desired search term to view the total number of registered users and Voucher accounts. Monitoring total users also covers user profile kinds, mac addresses, usernames, and passwords.

Figure 20 shows an active user. To find out which client is utilizing the cgr net Wi-Fi, type on the hotspot user page to monitor the presently active client. Id, username, IP address, uptime, byte IN, byte out, session, and login are all included in the message sent by the active monitoring client.

## 3.6 Optimize

Planning, starting with the necessary gear, software, and other requirements for bot design, such as observing network effects.
