<![CDATA[Pada Kontes Robot Seni Tari Indonesia (KRSTI), mengharuskan peserta untuk dapat membuat robot yang dapat menari secara otomatis dengan diiringi alunan musik. Tujuan penelitian ini adalah membuat robot humanoid yang dapat menari ketika musik pengiring diputar dan berhenti ketika musik berhenti. Penelitian ini menggunakan IC MSGEQ7 sebagai pengolah musik karena IC ini dapat membaca nilai frekuensi musik secara detail sebanyak tujuh frekuensi yaitu frekuensi 63Hz; 16Hz; 400Hz, 1kHz; 2,5kHz; 6,25kHz; dan 16kHz. Ketujuh frekuensi tersebut dijadikan acuan sebagai isyarat robot untuk bergerak atau berhenti. Penentuan frekuensi sebagai isyarat gerak didapat melalui sampling musik Tari Remo menggunakan perangkat lunak Matlab dengan metode FFT (Fast Fourier Transform). Isyarat gerak tersebut dikirimkan ke sistem robot melalui Modul Bluetooth HC-05. Jika sistem robot mendapat isyarat untuk bergerak maka robot akan menggerakkan servo penggerak menjadi gerakan yang serasi. Hasil yang didapat dari pengujian adalah dapat diketahui frekuensi yang sering muncul pada musik tari remo yaitu pada frekuensi 0-4000Hz. Setelah frekuensi diketahui, implementasi pada robot memperoleh hasil robot dapat menari ketika musik diputar dan robot dapat berhenti ketika musik dihentikan.At the Indonesian Dance Robot Contest (KRSTI), it requires participants to be able to make robots that can dance automatically accompanied by music. The purpose of this study is to create a humanoid robot that can dance when the accompaniment music is playing and stop when the music stops. This study uses IC MSGEQ7 as a music processor because this IC can read music frequency values in detail as many as seven frequencies namely 63Hz frequency; 16Hz; 400Hz, 1kHz; 2.5kHz; 6.25kHz; and 16kHz. The seven frequencies are used as a reference as a robot signal to move or stop. The determination of the frequency as a gesture is obtained through the sampling of Remo Dance music using Matlab software with the FFT (Fast Fourier Transform) method. These motion signals are sent to the robot system via the Bluetooth Module HC-05. If the robot system gets a signal to move, the robot will move the servo drive into a matching movement. The results obtained from testing are the frequency that often appears in Remo dance music, namely the frequency 0-4000Hz. After the frequency is known, the implementation of the robot obtains the results that the robot can dance when the music is playing and the robot can stop when the music is stopped.]]>

<![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[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.]]>
