Vehicle Security System using Short Message Service (SMS) as a Danger Warning in Motorcycle Vehicles

— Security system to alert and warn when a vehicle is stolen. This tppl aims to provide information to vehicle owners when a vehicle is in danger by sending coordinate points using SMS (Short Message Service) and can be displayed right with the Google Maps application to make it easy for vehicle owners to track or know the position of the vehicle. Vehicle safety system using SMS (Short message Service) and GPS (Global Positioning System) based on microcontroller and displayed with this smartphone utilizing technology that can make it easier for users to use, namely: (1) neo 6 GPS module, (2) the minimum microcontroller system circuit in Atmega Arduino uno module, (3) SIM GSM 800L module, (4) Smartphones, (5) as well as google maps applications and (6) SMS (short message service) which are already smartphones. Making software (software) this tool uses the C programming language and uses the MIT App Inventor Application.


INTRODUCTION
Private vehicles are valuable assets for everyone. Each vehicle owner usually has a way, each to protect the vehicle from damage or loss, with many cases of motor vehicle in Indonesia making the vehicle owner to always be vigilant [1]- [5]. Moreover, the missing vehicle will be difficult to find, one reason is the difficulty to track the whereabouts of the vehicle during the theft.
Various vehicle owner's efforts to improve the safety of motorbike vehicles that are being parked, both in the public parking area and on the home page, so as not to easily trigger theft. Then the author will discuss the results of a vehicle safety system research that can send a warning to the owner of a motorcycle vehicle if the motorcycle is stolen [6]- [9]. Besides that the device is equipped with GPS so the owner can see or know the position of the motorcycle vehicle [10]- [13].
Referring to the background of the problem, the formulation of the problem of this research is how to implement a security system on a motorcycle [14]- [17]? How do you get the results of testing on a motorcycle security system? The purpose of this study is to produce a tool that is able to track the location of a lost vehicle with a GPS module neo 6 and can produce a software design of a tool that can display the location of the vehicle in the form of a map on the google maps application on the smartphone of the vehicle owner (user) [18]- [20].
Referring to the problem formulation and research objectives, this study aims to create a vehicle safety system using SMS as a hazard warning on motorcycle vehicles.

II. METHODS
The making of this security system was carried out in the Net Centric Computing laboratory in the Informatics Engineering Study Program at UIKA Bogor and the testing was carried out at the UIKA Campus in Bogor.
The initial stage of this research is to make it easier for vehicle owners to track down stolen or lost vehicles. The diagram in Figure 1 explains the workflow of analysis, design, implementation, and testing. This needs analysis will require a tool allowance that will make it easy to resolve existing problems.

B. Design a. Hardware Design
Make a series of tools that will be used on each device in accordance with the design that will be built in the vehicle safety system.

b. Software Design
This stage makes C programming language which will be used to input the sim 800L module The GPS neo 6 to produce output on the vehicle security system.

C. Implementation
The process of implementing everything that has been designed both software and hardware design.

III. IMPLEMENTATION
The test results are divided into several sections including: 1. Testing Module Sim 800L 2. Testing Module GPS neo 6 3. Testing configuration the GPS 4. Testing the SMS application using the app inventor.
5. Testing the entire tool.

Test Results Module Sim 800L
a. Testing module Sim 800L In this test carried out aiming to test whether the module sim 800L work in accordance with the specifications that have been applies [21], [22]. As shown in the Figure 2. In the picture above is a test of the module sim 800L aims to send a hazard warning message when the vehicle is on.

b. Module Sim 800L voltage test results
This system is run requires a voltage from the microcontroller to function properly, her is a table of module sim 800L test results. From the test results in the Table 1, it can be analyzed that the module sim 800L will be active when the voltage of the microcontroller.

Testing Module GPS neo 6
This stage is to find out whether the GPS neo 6 is functioning properly or not and can receive GPS signals or not, like the  In Figure 5 this is the result of testing the Module GPS neo 6 aims at whether the coordinates are accurate or nit, and therefore requires this test [23]- [27].

Testing GPS Configuration
This test is conducted to determine whether GPS after being installed on a motorcycle vehicle can function optimally, with the voltage through the battery of motorcycle. The result is shown in Figure 6 and Figure 7.

Testing the SMS application using the app inventor
Inventor application is a tool to create fun applications from this tool, because it is based on visual block programming, so we can create applications without any source code. The Figure 8 is an SMS application that is connected to arduino, Module Sim 800L and Module GPS neo 6 [28]- [30]. In Figure 9 is the result of using the Inventor app that is connected to the module sim 800L and GPS neo 6.

Overall tool testing
Test results for the entire tool. The results of testing the delay time, the farther the distance between applications with provider will result in greater delay time, this is because the distance traveled by the data sent from the server to the SMS  Figure 10 and Figure 11.

IV. CONCLUSION
Based on the results and discussion, the following conclusions can be drawn. The hardware manufacturing of the vehicle security system using SMS as a hazard warning on motorcycle vehicles was successfully made with arduino uno supported by the software inside and combined with several series of mutual support. The making of this software uses a programming language C system that is made to work well.
