<![CDATA[ABSTRACT – The purpose of this research is to make CNC which has 2 functions in 1 system. By utilizing a USB serial for communication between a computer and a microcontroller. To operate CNC, the program is designed using LabVIEW software, the program will convert images into G-Code and send G-Code into the CNC system to do the plotter or laser engraving process. CNC plotter can make an image pattern on paper with a ballpoint pen automatically. Whereas CNC Laser Engraving can make a engraving on wood by utilizing laser heat, laser heat will erode the surface of the wood automatically. In designing multi CNC, 2 stepper motors are used as the axis actuator , and for the ballpoint pen drive uses a servo motor. The laser used for wood engraving uses a 500 mw laser diode. Based on the test results in this study, the program at LabVIEW can convert images into G-Code lasers, then the program send G-Codes into a CNC system, as the result CNC can process laser engraving on wood as well as set the thickness of the engraving as the need. The ideal feedrate is 50-500 mm / minute and the maximum is 2000 mm / minute. On the other hand, CNC Plotter is able to print a square shape image with the smallest size of 2 mm x 2 mm, and the circle with the smallest diameter of 2 mm with a 100% accuracy rate. The maximum dimensions of images that can be done by Multi CNC are 300 mm x 300 mm. Keywords – Multi CNC, LabVIEW, G-Code, Microcontroller.]]>

<![CDATA[The use of fingerprint machine as access attendance data has been widely used, both by the organization and the company. In the application, each attendance data is stored on the fingerprint machine, then the data can be withdrawn with various systems and processed further. Sometimes, some application developers use existing applications for the process of retrieving attendance data manually or with existing applications then done data processing with the application that has been created. Manual processing is usually done by retrieving data using storage media such as flashdisks and then exporting the data to the database. In addition, you can use the method by utilizing the facilities provided by simple Object Access Protocol and ZKEM control. In the research comparing the performance of both facilities in sending attendance data from the fingerprint machine to the database. The performance measured is the speed of data transmission and the accuracy of the amount of data transmitted by the fingerprint machine. The results obtained in this research that the delivery of attendance data using Simple Object Access Protocol and ZKEM control have the same data accuracy. Meanwhile, in terms of time delivery ZKEM control can send data 50% faster than using Simple Object Access protocol.]]>

<![CDATA[ABSTRACT – The use of JPEG image formats is increasing along with the increase in digital photo production triggered by the emergence of smartphones and the development of social media. Even in 2017 it is predicted that each person will produce 1,600 digital photos in one year. This makes JPEG files play an important role in digital forensic processes so that many JPEG file identification and recovery methods are developed. This paper attempts to look at the process of identifying and recovering JPEG files with the Signature-Based Carving method, the simplest carving method, with a Finite State Automata (FSA) diagram model, a basic algorithm model in computational theory. The FSA model that was created was then tested using data in the form of a disk image made publicly available from DigitalCorpora.org. The result is that the FSA model can identify and recover JPEG files with the Signature-Based Carving method with certain terms and conditions, including unfragmented, full headers and footers, and no thumbnail or embedded JPEG files in the JPEG file.]]>

<![CDATA[Hadoop is an open source and java based software framework. Hadoop consists of two main components, namely MapReduce and Hadoop Distributed File System (HDFS). MapReduce consists of Map and Reduce which are used for data processing, while HDFS is a places or directory where data can be stored. In carrying out a job that is not uncommonly diverse in its execution characteristics, a proper job scheduler is needed. There are many job schedulers that can be selected to matching job characteristics. Fair Scheduler uses a scheduler where the principle is to ensures that jobs will get the same resources as other jobs, with the aim of improving performance in terms of Average Completion Time. Hadoop Fair Sojourn Protocol Scheduler is a scheduling algorithm in Hadoop that can do scheduling based on the size of jobs provided. This study aims to compare the performance of the two schedulers for Twitter data characteristics. The test results show the Hadoop Fair Sojourn Protocol Scheduler has a better performance than the Fair Scheduler both from handling average completion time of 9.31% and job throughput of 23.46%. Then the Fair Scheduler excels in the task fail rate parameter of 23.98%.]]>
