Abstract

Application of security systems to oversee the security of a location using cameras is an alternative that is often chosen. Rather than hiring the services of many security officers, put the cameras in various corners of the place are more economical with less security officer and a camera operator. Job duration of camera operators on average for 6 hours to 8 hours, during this period the operators are required to oversee the monitors in the room. With the long work duration, operator attention is decreased so that the supervision task insufficient. There is no a supervisor for camera operator performance, so operator supervisor technology in real-time is made. By detecting the position of sitting or standing and face detection, then the attention of operators can be detected. Position detection of sitting or standing on this system using HSV color conversion to selecting pixels containing skin color as a value threshold, image Thresholding, and white pixel calculations from the top image and the bottom image. For human face and eyes detection used Haar Cascade Classifier Algorithm. This algorithm can detect the tilt angle of each face up to 15áµ’. The output of the system is the sound of the buzzer, indicates that the operator under the conditions of being out of attention. The system can detect the sit or stand condition with 100% accuracy, for face and eyes detection to determine the condition of attention of 98.33% accuracy.

Abstract

Audio recording is one of the multimedia files that are often encountered today. One example is the sound recording that can be used as evidence in the trial of the law. The proof of sound recording is supported by UU No 11 Tahun 2008 Pasal 5 ayat 1 regarding information and electronic transactions that stated : "Electronic information and / or electronic documents and / or prints are legal evidence". Therefore, sound recording is very important to be kept secret from an unauthorized party. This study focuses on the aspect of confidentiality. This research implements SPECK algorithm to encrypt audio recordings. DHKE is also implemented as a public key exchange algorithm. Execution time encryption and decryption is performed by using various files extension and the duration of different audio recordings. The time of encryption and decryption of each file extension is slightly different. The execution time difference of encryption and decryption is less than 23 seconds. The results show that the file extension does not affect the execution time. The execution time is affected by the size of the file, whichs mean the bigger the size of the file, the longer the execution time.

Abstract

Internet era at this time has developed a technology called Internet of Things as known as IoT. Where IoT is able to transmit data automatically from computer to computer without the initiation from humans. However, with size and number of data that increased will be transmitted make IoT devices performance has a negative result. Efforts are being made to overcome these problems, namely the need for a system that is able to manage devices and can monitor and maintain availability of IoT devices. One way is to make an IoT device monitoring system that aims to monitor when there is a disruption to the device. By implementing the MQTT protocol which is a protocol that implements the publish-subscribe mechanism and runs on the application layer. The MQTT protocol can process the send and receive of messages to manage and monitor according to the user's wishes, because the send and receive of messages by predetermined topics. Based on results rather than testing, the MQTT protocol has a smaller resource requirement than the UDP protocol and has a smaller data packet size than the SNMP protocol. The IoT device monitoring system that uses the MQTT protocol also has a small delay of 0.008634 sec and a throughput value of 9.2 MBit / sec. So that the system can run on low bandwidth and high latency.
