Design and Development of Automatic Fiber Optic Cable Roller using NodeMCU Esp 8266 Module

—The process of winding fiber optic cable rolls takes a long time because it is done manually or conventionally. One of the tools in winding is a FO cable roller. This tool is designed to be able to roll fiber optic cables, but the limitations of this tool are still done manually, FO cables are rolled by hand like pedaling a bicycle on the pedals, the speed is set based on the speed of the rotation of the hand and it all depends on the human factor. Therefore, there is a need for an Automatic Fiber Optic Cable Winder Using Node MCU ESP8266 and using Iot (Web of Things) to be more efficient and better in cable winding expositions.

INTRODUCTION FO links are heavily used by various organizations that provide web association access and correspondence as a component of sending image views, such as messages, voice, and data. Communication using FO cable is this medium using light as a conduit of information or data. (Muharor et al., 2019). FO made of plastic & glass can send quickly. Fiber Optic Cable plays a very important role in this industry, especially in terms of sending access and is highly favored in the future.
Likewise, many local exercises or exercises are currently being carried out at home, so web access providers are increasingly needed, especially networks that utilize fiber optic links. To achieve a better, shorter and more secure process, in terms of security. One of the models is the advancement of control in electronic gadgets, in this way the makers need to make programmable fiber optic splice rollers or referred to as "modified fiber optic splice rollers" in order to help as many people as possible. will be considered normal during winding. fiber optic connection. The development of science and technology in the field of automation can lighten work and make work easier and more effective and more efficient. At this time we can not be separated from electronic devices, in this invention I designed an automatic roller using a motor.
One example of the technology that will be used in this tool is the internet, where the development is very significant. One example of the technology that will be used in this tool is the internet, where the development is very significant, With change On this occasion, developments that can be controlled remotely via IoT affiliates are made to be more flexible.

Product Design
As for the planning stages of the Design and Build of the Optical Fober Cable Automatic Roller Using the Node MCU ESP826 Module, the beginning of the design formation, obtained materials and manufacture as well as run -up of the tool. So that it can achieve maximum results, because the author's goal is to create this tool.

2.
After that, Node MCU will give input or command to the relay after the program has been determined. 3. If the relay has detected a command, the motor will rotate and the roller will also rotate until it stops according to a predetermined program. 4. The motor work process is regulated by the Node MCU where the Node MCU has been programmed according to the work system described above. 5. Everything will work and then the LCD display will give a portrait display of the number of cable reels.

Product Test
In this product test, it will aim to display the results of the props functioning as expected or vice versa. If there is such a process, a review and process changes and a more detailed plan will be processed.

Rotary Encoder Test
In the design of this rotary encoder tool, it is used to change the rotary encoder's rotary motion into input for the microcontroller and is interpreted as a distance in m (meters).

Electric Component Test
• Individual tests are conducted to determine whether the components work normally and safely. • Checked on the power supply, the input power supply was given a voltage of 220VAC, then measurements were taken using an avo meter on the result port, the estimated effect of the result port on the power supply was 5VDC, and that means the power supply is in good condition and ready to use.

Mechanical Component Test
• Manually rotate the gearbox to ensure that the gearbox rotation is not hard and can rotate without obstacles.

Presentation and Analysis
Here is an organizing system by sorting data into patterns, categories as well as important details so that topics can be found and work theory can be planned as suggested by the information.

Data Presentation
The collection and presentation of data is a very important part of making a report or research. Each type of report must involve information in introducing the current reality and data contained in the report (Dr. Bambang Widjanarko Otok, 2016). After getting the data, the data obtained can be displayed in 2 views, namely tables and diagrams. In the process of this research will be detailed the presentation of data from the system, namely testing the rotary encoder and testing the measurement of cable length and determining the error value..

Mechanical Design Result
The following is a design view of the automatic roller.

Control Circuit
This circuit is a combination of electrical circuits placed in a P 8266, 5 volt 4 channel relay, 16x2 . LCD

Design Results on Blynk
The following is a display of the results of the initial input design of the fiber optic cable winder consisting of several initial views 1. Apps This view is the blynk application which is displayed after the user opens the application and the user can press the button from several choices of the number of cables they want to roll according to the images and programs that have been set on the module..

Test Results
Testing the tool serves to obtain whether the cable length measuring device is running as expected. The table below shows the test results getting a small error value.
The test experiment obtained the average of the tool and the calculation in this algorithm uses the following formulation: Distance = (( 2 x π x r ) / N) x counter Description π = 3,14 ( pi ) r = wheel spokes ( 10 )  Graph of measuring cable length and determining the error value. An error or problem was found in every rotary encoder experiment, this was due to sensor limitations.

Conclusion
With the process of making the Design of Automatic Fiber Optic Cable Winder Using the ESP8266 NodeMCU Module, it can be concluded as follows. 1. The results of the design of this tool can operate properly. 2. The results of the design of this tool are made to facilitate and shorten the time of winding fiber optic cables more quickly and efficiently. 3.
