To clean the floor, it can be done manually by using a floor mop along with floor cleaning fluid, but this will result in a floor that is already clean. Still, the implementation time is long enough to interfere with the time of mothers who are office workers or manufacturers to help their husband's income. . In the process of cleaning the floor, cleaning the floor can be done until the floor is clean so that the children are comfortable playing on the floor. The process of cleaning floors can be done in various ways, either manually or automatically. To clean the floor with a large floor size more quickly, the floor is cleaned with machine power. But the range and limitations of floor cleaning machines exist. So it is necessary to make a robot that works automatically without human assistance to do the cleaning so that the job is done quickly and the area limit of the cleaning results is greater. The system will work using penggerak technology remotely using Bluetooth. This system aims to connect communication between wheeled robots and smartphones via Bluetooth communication media. From the test results, the author has successfully applied Bluetooth technology to a wheeled robot by providing instructions such as forward, backward, turn right, turn left, and stop. This robot is used to clean floors quickly and practically so that it can be done by itself.

In the era of the industrial revolution 4.0, there are very many significant changes to information technology. Advances in information technology so quickly innovate in various circles of society, thanks to this progress people can carry out all activities quickly and accurately. So that the effectiveness and efficiency of an organization or agency will be good. For example, in correspondence activities at the BKPSDM, Sukabumi Regency, initially letters were made by hand and then sent through intermediaries to certain individuals or agencies and vice versa then with the existence of information technology, correspondence activities were made easier in terms of manufacture and delivery. But with this convenience, there are still some obstacles experienced, namely the existence of data redundancy, accumulation of mail data, and the absence of multi users, this causes coordination problems in each field which has an impact on the delay in processing incoming and outgoing letters. This is because the company does not yet have a management support system to bridge correspondence activities and an unorganized reporting system. To overcome this, a suitable information system management model is needed, in this study the model used enterprise architecture with the Zachman Framework method. The focus of the problem in this research is to optimize the flow of correspondence and mail reporting activities using a website-based system as the medium. The results obtained from the Zachman Framework enterprise architecture are in the form of a blueprint or blueprint which will later be used as a reference in system implementation.

Various techniques are used to protect digital information, especially information that is kept secret from people who are not entitled to the right of access to information, one of which is the technique of steganography. Steganography technique is a technique used to secure data by inserting or hiding data into an object without changing the shape of the object; one of the objects is a digital image. The steganography technique also has several methods, namely the Spread Spectrum method. Spread Spectrum is a method of communication where information signals are spread across all available frequencies by selecting where to insert data at low frequencies and adding pseudo-noise (PN). This study secures text data with the Spread Spectrum steganography technique on digital image objects by the steps of changing the value of the RGB pixel image and text data into binary, spreading the text data, followed by key generation and the modulation process of spreading text data with the generated key results. To produce a stegano image with an RGB pixel value that changes the value of 0 to 1 value that does not affect the color reproduction of the RGB pixel image.
