Security in driving is aimed at the way of driving the vehicle or the security on the vehicle itself. Vehicle assets, especially cars, that are quite expensive or luxurious assets Therefore, safety protections for such vehicles are necessary. Taxi is a valuable asset for the company. To maintain the asset, a good security system is needed. With a good security system, the asset will be protected and the investments invested will not be reduced. By using the prototype method, a tool will be made in accordance to the wishes of the user. The Encludean distance method is used to calculate the distance of the incident and the nearest police station. By using the progress of technology, the progress can be utilized to help the security of taxi owned by a company or personal (online). The purpose of this study is to create a tool that can secure the taxi and its driver of crimes that might occur. IoT (internet of things) can help to secure a taxi since it is able to locate the incident’s location precisely and accurately.

Introduction Security in driving is aimed at the way of driving the vehicle or the security on the vehicle itself. Vehicle assets, especially cars that are quite expensive or luxurious assets. Therefore, safety protections for such vehicles are necessary. Taxi is a valuable asset for the company. For that, a good security system to maintain the asset is needed. With a good security system, the asset will be protected and the investments invested will not be reduced. The taxi security system has actually been regulated in the Regulation of the Taxi Industry [1]. With the development of increasingly advanced technology nowadays, it is necessary to improve the current security system. Crime within the taxi may occur on the driver or on the passengers [2]. There are two types of taxi in Indonesia, the official taxi and the online one. Crime on taxi drivers lately is quite common, especially with the opening of the online taxi service in Indonesia. As recently, there was a robbery and murder of a taxi driver in Sukabumi. Technological progress has been developed so rapidly, as seen on its usages in the community [3, 4]. It is used ranged from the use of household appliances to mobile phones. When talking about mobile phones, there are so many applications contained in the phone, like WhatsApp, SMS and internet [5]. When talking about the internet, then the application from the internet is really vast. One of them, is by implementing the internet to control the equipment known as IoT (Internet of Things) [6, 7]. When we are talking about IoT, then there are many advantages that can be obtained from IoT [8]. Currently IoT has penetrated into all areas such as in the field of health, engineering, and security fields [9, 10]. By using IoT, a variety of devices can be communicated through the communication network. The device in question can be either smart devices or computers. By using IoT many benefits can be obtained, especially if the IoT is connected to a computer or Embedded System [11-13]. From security problems on Taxi and IoT (Internet of Things), the writers try to do a research about Smart taxi and IoT. The use of the existing mobile phone should be utilized by taxi owners to secure themselves and their assets. By using a short message via SMS or WhatsApp, one can find out where someone is located and tell the person's position. WhatsApp or SMS is a means for people to carry out communication [14, 15]. Thus, there are millions of
