The topic that is currently being discussed is Covid-19. Covid19 is a disease caused by the corona virus, which was first identified in the city of Wuhan, China. This disease has spread throughout the world, including Indonesia. In this regard, the Indonesian government issued a policy as an effort to break the chain of the spread of the corona virus. However, this encourages the emergence of various kinds of public responses. One of them is Twitter users, there are pros and cons responses from the community in responding to government policies and causing problems, namely the difficulty of knowing positive, neutral or negative responses given by the community.

Abstract

Wireless networks / hostspot using wave or signal transmission media. Waves or signals emitted from a device called an access point having a particular frequency. Signal beam is formed a circular pattern in which the antenna from the access point to the source signal. In a wireless network signal is captured and used a computer to be able to communicate with each other. PING technique is a method to double check the connection by sending data packets from the sending computer to the destination computer. This process can be seen from the travel time required to transmit data packets. So there is some problems how to convert time obtained from the PING into the distance. Algorithm Jawa can be used to convert units of time-based PING the wireless LAN / hostspot into the distance. Basically, two computers that are in a wireless LAN / hostspot will form a triangular pattern. This pattern will be used algorithm jawa to determine the distance between two computers within the wireless LAN / hostspot by utilizing modifications pythagorean theorem for isosceles triangular pattern and the large angle of 400.

Abstract

Synchronization is the process of setting the course of several processes at the same time. Synchronization builds upon students' academic value table STTA Yogyakarta by comparing records for the records in the database. If there is a difference in the academic value of the table the different values will be returned as the value of the original with comparing by using the master database. Record based table synchronization is expected to address the security system on the database and provide security guarantees a safe and comfortable.Authentication is a process by which a user is identified by the server before the user using the network. In the process, the user is requesting access rights to the server to use a network. Authorization is the allocation of what services are entitled to be accessed by the user on the network. Authorization is done when the user has been declared eligible to use the network. Accounting is a process performed by the server to record all user activity in the network, such as when the user starts using the network, end user when the connection to the network, how long the user using the network, how much data is accessed from the network user.The results of the implementation of synchronization using a table based record system security authentication, authorization, accounting changes that may prevent the occurrence of data in a database, optimizing the use of stored, and enhance security systems at the database STTA center of Yogyakarta.

Abstract

Development of the world's information and communication technology-based growing rapidly. The development of these technologies has given rise to another dimension in human life, namely the need for computer use. Application of machine vision applications where a computer has the ability to understand the data in the form of image and make decisions based on data obtained from a real object, in this case is generated through the capture image from webcam.            The images (digital images) of a real object through a webcam can be done in many ways capture the object. In this research object retrieval using an object of activity is captured on the webcam through the motions of objects. Digital image acquisition is performed with the tool in the form of software (Obtion Remote Version 1.0). Obtion (Object Detection) method works with the system of comparison between that time frame the previous frame captured by the camera at the time of recording the object. Comparison of the difference in the frame will be accommodated in a place that will be used to support the execution of an object by counting the number of pixels that exceed the value of the difference in number of field values with regulator frame to frame changes in the location of the object motionObtion Remote Version 1.0 will take a digital image of the object with trigger object motion detection performed. Digital image acquisition (capture the object with a webcam) will be done automatically if the object has been successfully detected. The detected object will be stored automatically in the directory are executed as a digital image storage.
