Abstract

Abuse is not only done to copy or distribute data but also to the digital copyright labels. There is a way to protect data by inserting or hiding a piece of certain information, namely a watermarking technique. In this paper, we propose audio watermarking with Quantization Index Modulation (QIM) method as an embedding process combined with Compressive Sampling (CS), Discrete Sine Transform (DST) and QR decomposition. Binary image is used as a watermark inserted in host audio. DST is used for transformation process from time domain to frequency domain, while QR is used to decompose onedimension matrix into two-dimension matrix. Meanwhile, CS is used to obtain the compressed watermark file which is done before the embedding process. QIM method is used to embed the watermark file to the audio host file. Simulation results indicated that the proposed audio watermarking technique has good robustness against some attacks such as Low Pass Filter (LPF), resampling and linear speed change. In addition, it provides good performance in terms of imperceptibility with Signal to Noise Ratio (SNR) > 20 dB and capacity C = 689 bps.

Abstract

Circulator merupakan perangkat elektronik yang memiliki fungsi penting pada suatu sistem pemancar dan penerima gelombang frekuensi radio (RF), di mana magnet permanen dapat berfungsi sebagai pengarah gelombang (waveguide). Penelitian ini bertujuan untuk menggantikan magnet permanen barium ferit (BaFe12O19) yang umumnya digunakan pada circulator dengan magnet permanen berpengikat (bonded) neodymium besi boron (NdFeB). Bahan baku yang digunakan adalah serbuk NdFeB crashed ribbon dengan menggunakan metode pengepresan green-compact yang divariasikan pada tekanan 25, 50, 75, dan 100 kg.cm-2 dan dilanjutkan proses pemanasan pada temperatur 200 C selama 60 menit. Karakterisasi sifat magnet dilakukan dengan Permagraph, diperoleh nilai intrinsik optimum dari sampel 100 kg.cm-2 , induksi remanen (Br) = 5,37 kG, koersifitas (HcJ) = 4,74 kOe, produk energi maksimum (BHmax) = 2,39 MGOe, dan densitas (ρ) = 4,89 gr.cm-3 . Hasil pengukuran kuat medan permukaan (B) dengan Gauss-meter menunjukkan nilai 800 G. Magnet dengan karakteristik optimum diterapkan pada circulator kemudian dikarakterisasi dengan Vector Network Analyzer dan menghasilkan voltage standing wave ratio (VSWR) = 1,354, isolasi = -17,165 dB dan kerugian penyisipan = -0,200 dB pada titik kerja 3,00 GHz, sehingga magnet berpengikat (bonded) NdFeB ini dapat diterapkan pada S-band circulator yang bekerja pada rentang frekuensi 2,00-4,00 GHz.

Abstract

Wireless sensor networks consisting of sensor nodes can be used as an effective tool for collecting data in various situations. Nodes are usually placed randomly in an area to perform sensing and monitor various parameters related to environmental conditions in various locations. One of the major problems in wireless sensor networks is developing energy-efficient routing protocols that have a significant impact on the overall life of sensor networks so it is important to make energy savings in these limited energy sources to extend network life. This paper proposes a hardware design and Low-Energy Adaptive Clustering Hierarchy (LEACH) routing protocol configuration for power saving by utilizing cluster head selection mechanism. The cluster head selection process is performed periodically based on LEACH algorithm enables the node to have the best lifetime responsible for communication between the nodes and the server as well as the effort to save energy consumption of limited energy sources to extend network life. So that makes the process of sending information more effective and optimal. The system has been able to display data information along with the position of nodes in the web server with an average of 42 seconds of computing time in a rotation of the system so that it can be done 85 times in 1 hour. The system is able to provide real-time information with a throughput of more than 1.052 Kbps and packet loss of no more than 6.7%. In addition, energy savings can up to 6.5% of the existing energy in a lithium battery.

Abstract

Perkembangan budi daya ikan yang menggunakan keramba jaring apung (KJA), saat ini tersebar di berbagai waduk dan danau di seluruh Indonesia, saat ini tumbuh pesat dan menjadi andalan pendapatan daerah. Selama ini monitoring kualitas air dilakukan secara manual, yaitu melakukan pengukuran kualitas air di tempat budidaya ikan tersebut. Selain memerlukan waktu yang lama, biasanya budi daya ikan tersebut berada jauh dari pusat kota. Dalam makalah ini akan dijelaskan desain dan realisasi sistem monitoring kualitas air dan peringatan dini secara real-time yang terintegrasi. Sistem ini telah diterapkan secara khusus untuk memantau parameter suhu, DO (dissolved oxygen) dan pH di sentral budidaya ikan di Waduk Cirata. Tujuannya adalah memantau kualitas air secara real-time, bisa diakses di mana saja dan sekaligus mencegah kematian ikan secara massal yang disebabkan oleh terjadinya up-welling dengan menggunakan sistem peringatan dini. upwelling terjadi apabila nilai suhu menurun drastis mencapai 25 derajat celcius lalu nilai DO menurun sampai 2,38 mg/L. Di sisi lain, data dari stasiun pengukuran yang dikumpulkan di stasiun perantara dapat diakses atau dikirimkan ke stasiun pengendali dengan menggunakan sistem telemetri. Hasil dari penelitian ini memperlihatkan suatu sistem monitoring kualitas air untuk memantau parameter suhu, DO dan pH sekaligus peringatan dini terjadinya upwelling. Sistem ini untuk mendukung pembudidayaan ikan di danau-danau di Indonesia.
