Abstract

Ease process digital data information exchange impact on the increase in cases of copyright infringement. Audio watermarking is one solution in providing protection for the owner of the work. This research aims to optimize the insertion parameters on Modified Discrete Cosine Transform (M-DCT) based audio watermarking using a genetic algorithm, to produce better audio resistance. MDCT is applied after reading host audio, then embedding in MDCT domain is applied by Quantization Index Modulation (QIM) technique. Insertion within the MDCT domain is capable of generating a high imperceptible watermarked audio due to its overlapping frame system. The system is optimized using genetic algorithms to improve the value of imperceptibility and robustness in audio watermarking. In this research, the average SNR reaches 20 dB, and ODG reaches -0.062. The subjective quality testing on the system obtains an average MOS of 4.22 out of five songs tested. In addition, the system is able to withstand several attacks. The use of M-DCT in audio watermaking is capable of producing excellent imperceptibility and better watermark robustness.

Abstract

Dewasa ini, banyak aplikasi yang dibuat dengan melibatkan fitur multimedia. Salah satu aplikasi tersebut adalah aplikasi konferensi, yaitu komunikasi yang dilakukan oleh suatu group yang terhubung pada suatu jaringan dengan setiap anggota group dapat saling melihat anggota yang lain melaluifasilitas video yang direkam menggunakan sebuah piranti webcam. Dalam komunikasi video, dibutuhkan bandwidth yang cukup besar karena ukuran data video yang jauh lebih besar dibandingkan data suara. Untuk menyiasati hal tersebut, maka dilakukan kompresi pada video sebelum ditransmisikan. Dengan adanya kompresi, maka ukuran data video yang akan ditransmisikan menjadi lebih kecil sehingga dapat menghemat bandwidth saat transmisi data berlangsung. Dalam penelitian ini dirancang codec yang mengadopsi standar kompresi video H.264. Selanjutnya dianalisis kualitas video hasil kompresi meliputi : rasio kompresi, Peak Signal-to-Noise Ratio (PSNR), dan Mean Opinion Score (MOS). Selain itu, juga dianalisis pengaruh kompresi video terhadap kinerja aplikasi konferensi video. Dari hasil penelitian yang dilakukan, didapatkan hasil bahwa dengan adanya kompresi H.264 menghasilkan bitrate video yang rendah dengan penurunan mencapai 98.7% (1:77) hingga 99.52%(1:208) dengan PSNR minimal 30,90 dB.

Abstract

Produk digital seperti audio, image ataupun film merupakan karya intelektual yang dilindungi dan memiliki hak cipta. Banyaknya penggandaan dan klaim atas produk digital tersebut mengakibatkan pemegang hak cipta yang sebenarnya akan dirugikan. Salah satu cara untuk melindungi kepemilikan produk digital adalah dengan menyisipkan atau menyembunyikan suatu informasi, misal data pemilik hak cipta, kedalam produk digital tersebut atau yang disebut dengan digitalwatermarking. AudioWatermarking adalah suatu teknik menyisipkan atau menyembunyikan suatu informasikedalam suatu file audio. Pada penelitian ini menerapkan metode Discrete Cosine TransformsertaBCH code sebagai pengoreksi error. Sistem menghasilkan capacity yang besar yaitu 700 bps-2 kbps, perceptual quality yang cukup baik (SDG> 3.85 dan 25 dB < SNR < 56 dB) sertarobustness yang baik terhadap beberapa serangan yang umumseperti kompresi MP3, Noise, Echo dll.

Abstract

Nowadays, almost all data transaction is done through the internet because it is easy and could be accessed anywhere. The file is uploaded directly without any security or scanning making people able to upload illegal files or files that is not owned by them. This violation of copyright becomes a huge problem as it reduces the owner’s profit. That is why watermarking method is created. Watermarking is a method of embedding secret information to a host data. The information could be embedded into an audio, image or video data. This research will design an audio watermarking by combining 3 methods of transformation: Stationary Wavelet Transform (SWT), Discrete Cosine Transform (DCT), and Singular Value Decomposition (SVD). SWT separates data’s frequency into high and low. After that, DCT maps correlated high frequency data into uncorrelated coefficient. Then those coefficients will be deconstructed into three matrices u, s, and v using SVD method. Later, the s matric will be embedded with the watermark. With these methods, watermarked audio produce SNR>20dB and BER≈0,1170 in average.

Abstract

Bojongsari Village (Bojongsoang District) is a village located in Bandung regency. The village has a low Human Development Index (HDI). The village has a high open unemployment rate. The village of Bojongsari has a relatively low growth rate of living eligibility (based on data obtained from Bojongsari village). The training for the youths of Karang Taruna in the village of Bojongsari, especially for those who still do not get a job is a solution offered in order to reduce the number of open and underemployed unemployment in the region. The trainings that have been carried out include enhancing the ability to use computers, office applications (word, excel, and powerpoint), and Windows applications and networks in both villages. It is expected that with this training, unemployment will decrease and increase the HDI of both villages. The implementation of community service is evaluated monthly and a roadmap has been developed to improve the HDI of these two villages as a model for other villages in Bandung regency.

Abstract

Artificial Intelligence (AI) is a system developed to learn and apply human intelligence. Some technologies produced from the development of Al are face recognition and web scraping. Face recognition is used for identifying or verifying the identity of an individual using their face. The result of a face recognition process can be used to collect information on the internet with a web scraping technique. This paper proposes a face recognition model and web scraping system using You Only Look Once (YOLO) object detection method and Request library written in Python. The face recognition model performed fine-tuning in two hyperparameters, which are learning rate and step training. The proposed model for face recognition is using custom datasets that contain 8000 images divided into 5 classes and evaluated using the Mean Average Precision (mAP) performance parameter, while the web scraping system is evaluated using the precision rate parameter. From the test results, the best configuration was obtained at a learning rate of 0.0001 and step training of 10K. The highest mAP that is achieved is 0.90 with a recall and precision value of 0.75 for each, while the average precision rate is 0.87. The results of this paper are expected to contribute to the development of biometric security technology.

Abstract

data in an image file is needed by its owner to set his ownership in a logo as a watermark embedded in the image file. Hiding the logo in the image was done in several methods. One of the method is domain transform using 2D-DCT in which data is embedded in  frequency domain of the image. First, the host RGB image is converted to certain color space. The available and chosen color spaces are RGB, YCbCr or NTSC. The layer in which the watermark is embedded also can be selected. The available choices are 1st layer, 2nd layer, 3rd layer, 1st & 2nd layer, 2nd & 3rd  layer, 1st & 3rd layer and all layers.  After the selected layer of image in certain color space is transformed in block based to frequency domain by DCT, one bit watermark is embedded on the AC coefficient of each block such a way that the bit is represented by specific value called delta in a zigzag and vary length of pixel. The vary parameters optimized by Genetics Algorithm are  selected color space, selected layer, block size, length of pixel to be embedded by one bit watermark, and delta. Bit “1” is represented by +delta, and bit “0” is represented by –delta in vary length of pixel after zigzag. The simulation result performs that GA is useful to search the value of parameter that produces controllable the combination between robustness, invisibility and capacity. Thus, GA improves the  method by determining the exact value of parameter achieving BER, PSNR and payload.

Abstract

The industrial revolution 4.0 greatly impacts the learning curriculum, especially at the vocational and higher education levels. They are required to play an active role in the success and acceleration of the implementation of industry 4.0. Higher Education becomes a kind of place for preparation or training for human resources (HR) to provide skills that are directly related to the application and development of applications that support industry 4.0. In order to support the government's efforts, the community service team at Telkom University and the Telkom Jakarta Institute of Technology actively participated in collaborating with SMK Nagrak Purwakarta. This community service focuses on bridging productivity between departments in Nagrak Vocational School such as the Food Crops and Horticulture Agribusiness (ATPH) department and the network computer engineering department (TKJ) so as to produce the right cultivation, namely Internet of Things (IoT) based aquaponics. This activity consists of making modules and video tutorials for students and teachers, designing sensors and devices, and making monitoring applications on smartphones to monitor aquaponic plants. The sensor designed consists of a PH detection sensor in the air and an oxygen sensor installed in the school's aquaponics garden. The students and teachers were enthusiastic in participating in workshops regarding IoT materials. Not only getting material, students and teachers then do direct practice to make aquaponics and monitor temperature. Based on a survey of the results of this community service implementation, teachers and students are very satisfied and enthusiastic about and hope that community service activities can be carried out on an ongoing basis.
