Learning from the development of new technologies using the Internet as a monitoring medium, it can be ascertained that gps can be applied in various fields. These gps systems offer efficient improvements in vehicle monitoring and obtaining accurate and real time data. That with thedevelopment of new technologies that can be done that was the work-manual work using a computer that is Raspberry Pi. Data collection method is done by observation method, interview method and literature study, tool design method is done by using Fritzing application as a tool to design the system to be made and design of prototype to be built. But so far some are still local (Intranet), such as Infrared, Bluetooth and Wireless LAN. With the latest technology changing the local paradigm (Intranet) into IoT / Internet Protocol Based. In designing this tool required Raspberry Pi as Gps media as well as vehicle monitoring media using GPS, equipped with GPS module as a monitoring medium with ease. The creation of this tool may make it easy for vehicle owners to monitor vehicles remotely and provide reports in realtime.

The development of informatics technology offers organizations the ease of providing a new solution for the improvement of the less ideal system. SPKT (Sentral Pelayanan Kepolisian Terpadu) is the place of public complaints service regarding assistance from the police when there is a crime orcriminalization, report etc. It needs innovation in public service report system to Polresta Tangerang to be more effective or efficient. In overcoming the problem Alarm Panic Button System can provide convenience to contact the Police when there is a crime. The design of the tool begins by creating a prototype tool with a circuit consisting of several components. Then the tool assembled and embedded the script by using software Arduino Uno v3.0 which is connected with SIM Module 800L GPRS GSM Micro Sim as the part of the circuit to send the message. The message will be sent directly to Polresta Tangerang. The purpose of the study can be to provide services with an access to facilitate the publicin informing and reporting criminal or other crimes to the police about events occurring at work, home or market. So the police are able to find out earlier about the incident and then take quick action to overcome it.

Data is a very authentic evidence that need to be saved because the data are at risk of data changes by the party who wanted to misuse the data or no effect on the data. Therefore, so that no unauthorized person to change the existing data, stored or can take the data that is very important, we need a method to be able to secure and keep data. The database is used to keep data and information. The whole system stores the data in the database, so that the contents of stored data security and confidentiality must be maintained. To maintain the security of a security that is required cryptography. With the use of databases that are in can be connected to each other, Database is not just a place to store data,Computer security system is needed at this time in line with the increase use of computers in the world. So existing data security has become seriously threatened to be accessed by people who are not responsible. Computer security becomes very important at this time because it is related to the privacy, integrity, authentication and confidentiality. Thus data need to be stored by using the correct storage techniques, so that the confidentiality and security of data is maintained. Cryptographic techniques with engineering data encryption on the database is one solution that can be used to meet the confidentiality and Data Security settings. With the existence of a cryptography that includes the encryption process, the data in the database can be encoded so that unauthorized persons can not read the information, in addition to those who know the key to describing it. Security of data / information document with a cryptographic technique that uses the Blowfish algorithm chosen method for cryptographic key modernmerupakan shaped symmetric block cipher. Blowfish algorithm which can encrypt text built in text form. Encryption is done using a specific key, resulting ciphertext that can not be understood. The ciphertext can be changed back as the beginning if the decryption using the same key in the beginning when the database mengekripsi.

The integrated police service center (SPKT) is the place for managing public services in the form of receiving reports and handling the first reports and complaints from the public. The issue of technological development is also included in the criteria of police services in supporting the management of public services in order to obtain information and solve problems quickly and accurately. Therefore, there needs to be innovation in the public reporting service system in the area of Polres Kota Tangerang. The Warning Button Crime System is a tool that can make it easy for people to contact the police when a crime occurs. This tool consists of two parts, namely the transmitter side which is stored in the strategic area and the other side is the receiver stored in the police station. By utilizing the Arduino nano and uno microcontroller which is connected to the SIM 800L Module, it can function to send a message to the Polres Kota Tangerang, with the aim of being able to provide services easily to the public in notifying and reporting criminal acts or anything else to the police. So that the police are able to know more about the location of the incident correctly and can take preventive actions to overcome it. The management of changes made within this police institution can improve performance efficiently and effectively towards the achievement of objectives to ensure public security.
