<![CDATA[Speech recognition is a technique that allows a computer system to receive input in the form of a spoken word. The words are transformed into digital signals by changing sound waves into a group of numbers and then adjusted to certain codes and matched with a pattern stored in a device. The results of the identification of spoken words can be displayed in written form and can be read by technological devices. The tool in this study was designed to be able to help people with hearing impairment so they can participate in prayer in congregation in knowing the changing movements of prayer. This tool is designed with an Arduino Nano microcontroller board as a voice processing function received from speech recognition. The results issued by this tool in the form of vibrations that will be directly felt by the user. Presentation of success will increase if the sound around the input is not too noisy. Presentation of success in the words "Allahu Akbar" reached 82%, "Sami'allahu Liman Hamidah" reached 90%, and "Assalamualaikum Warahmatullahiwabarakatuh" reached 80%.]]>

<![CDATA[One of the uses of this sound technology is controlling the speed of a DC motor. Sound in the form of a spectrum signal can be converted to digital. Digital signals can be used as a microcontroller input to adjust the speed of a DC motor using the PWM (pulse width modulation) method. The design of the tool uses the V3 voice recognition module to convert the voice into digital. A microcontroller as a voice data processor by changing the input voltage to a DC motor. Voice command to set DC motor speed. Based on the results of tests carried out in good environmental conditions, 90% of voice commands can be recognized. Meanwhile, in bad environmental conditions by 50%. Manual measurement is done by entering the input voltage from 1 volt to 10 volts. The results of the comparison show that the speed is almost the same, namely 2727 rpm for manual calculation and 2915 rpm for the whole tool. This difference occurs because the test when manually inputting the tension is not very accurate. It can be concluded that the tool is working properly and as desired. If the environmental conditions are bad only 50% can be recognized from 30 voice commands, then there is a difference in voice intonation during the training process.]]>

<![CDATA[The openness of access to information raises various problems, including maintaining the validity and integrity of data, so a network security system is needed that can deal with potential threats that can occur quickly and accurately by utilizing an IDS (intrusion detection system). One of the IDS tools that are often used is Snort which works in real-time to monitor and detect the ongoing network by providing warnings and information on potential threats in the form of DoS attacks. DoS attacks run to exhaust the packet path by requesting packets to a target in large and continuous ways which results in increased usage of CPU (central processing unit), memory, and ethernet or WiFi networks. The snort IDS implementation can help provide accurate information on network security that you want to monitor because every communication that takes place in a network, every event that occurs and potential attacks that can paralyze the internet network are monitored by snort.]]>

<![CDATA[Abu Robocon 2018 which was held in Vietnam with the theme "nem con" which means throwing a berkah ball. The Indonesia Abu Robot Contest 2018 made a throwing robot design with different pole height. The parameter that must be achieved is the optimization of the throwing mechanical drive. The thrower mechanics in the KRAI robot can use pneumatically by determining the angle of the robotic thrower. The mechanical tilt angle determines the throwing distance of the berkah ball. To find out the height of this research berkah ball will use python to display the parabolic motion. Based on the results of the study obtained the first test results with a throwing angle of 0 ˚-115 ˚ get an average value of a distance of 7.37 m, height 273.4 Cm, time 1.42 s and speed of 5.152 m / s. The results of the two test with a throwing angle of 0 ˚-95˚ obtained an average distance of 8.78 m, height 352.4 Cm, time 1.63 s and speed 5.381 m / s. It can be concluded that the mechanical tilt angle is leaned forward, the pitching results will be lower. When the angle of inclination is tilted backwards the berkah ball will soar more.]]>

<![CDATA[This research proposes a wireless communication between two dancer robots using zigbee to overcome the differences in movement between the robots in order to dance in harmony. The robotic music processor uses Audio Analyzer V2.0 which functions to get 7 frequency values for the music being played. The frequency will be processed by Arduino to determine the condition of the music on and off which will be sent to each robot via the XBee S2C module using the Zigbee method, namely with 1 master and 2 routers. The result is that the music processing system becomes more robust because it uses the Zigbee method. By using the Zigbee method, robot 1 and robot 2 can also communicate with each other because with this method, fellow routers can exchange data. The robot produced by this study can already distinguish the conditions when music is playing or muted, and between robot 1 and robot 2 can communicate with each other. Communication between robots functions so that when one of the robots is late in getting data, the other robots will wait until the late robot completes its movements so that robot 1 and robot 2 are back in sync.]]>

<![CDATA[The conventional method of drying coffee beans that depend on sunlight (drying) has a number of drawbacks, one of which is that the drying productivity takes a long time. In general, coffee drying is carried out until it reaches a moisture content of 12.5% to achieve a quality bean standard. Mathematically, the moisture content can be assessed by paying attention to the initial weight of the coffee beans and the final weight of the coffee beans. So that the use of the Load Cell sensor to read the depreciation value of the coffee bean weight on a coffee dryer powered by Hybrid Collector and LPG coffee beans. Research that has been carried out during 200 minutes of drying in a coffee dryer, the Load Cell sensor is able to read the depreciation value of the coffee bean weight by 114 grams from the initial weight of 978 grams. Therefore, it can be concluded that the final moisture content of coffee beans has reached 12.01% and the final weight of coffee beans is 864 grams.]]>
