<![CDATA[In doing microwave transmission interference and attenuation effects , not so much propagation Line Of Sight. Therefore it takes a computation and checking of a transmission network that values ??of interference does not greatly effect the availability value is supposed to be, there are several ways to avoid or even eliminate interference case is to replace the sub-band and change the polarization of the antenna system microwae. On the transmission network owned by Axiata PT.XL Banten there is a case of interference, namely the link Panimbang Hop-Labuan-Cigeulis due to using the same frequency and the same sub-band. RF Scanning seen from the results that the link is indeed indicated interference. Therefore, by using software pathloss 5.0 will be able to do an analysis of a link or network terinterferensi. so as to reduce and resolve a case interference occurs, and the value of a link availability can be well worth it. Optimization is done there will be a change of the ODU or replace the antenna polarization between vertical or horizontal. Optimization to do is replacing frequency channel that was using 1h (high) - 1l (low) the frequency is 7747.70 MHz-8059, 02 MHz, to frequency channel 3h (high) - 3l (low) the frequency is 7807.00 MHz-8118.32 MH. By doing this method interference value will be lost. Then after the optimization of the value of availability to 99.99993%.]]>

<![CDATA[In wireless communications, demand to provide high-speed data services with good performance raises new techniques to increase spectrum efficiency and improved signal quality due to frequency selective fading. OFDM is a multi-carrier technique can be used to accommodate all these requirements. But in its development, this OFDM still has some weaknesses such us still large PAPR values and lack of power spectral efficiency improvements, OWDM used to overcome these deficiencies. In OWDM, inverse wavelet packet transform (IWPT) is used to generate the transmitted symbol on the transmitter and the forward wavelet packet transform (WPT) will restore the transmitted data symbol on the receiver. The OWDM system will divide the frequency band into several sub-bands that independent and isolated spectral called subchannelization. From the test simulation obtained OWDM give some things that can be compared with OFDM. In PAPR reduction, OWDM lead in reducing the PAPR. In OWDM case, the smallest PAPR value is produced in small-order wavelet, Coiflet, use few sub-bands and QPSK modulation.]]>

<![CDATA[The problems on the Coupled Tank control level is the existence of disturbance in the flow that supplies tank would make unstability response, so it could happen the cross interaction between input and output. PI control is an attractive option when the formulation of the proposed method to the Coupled Tank TITO system. PI control has the ability to maintain a steady state value of the response of the disturbance. In this study, it use Decoupling in cross interaction processes for every tank. Coupled Tank on TITO system can changes transfer function to SISO, so it can minimize the effect of interactions. The good way to design a model is consider the state on that plant, so the desired control model capable save non-linearity from TITO system. The simulations show value of percent overshoot (Mp), settling time (Ts) and steady state error (Ess), of the state of each system was 0%, 38 seconds, and 0.22%.]]>

<![CDATA[Harmonic is one of sinusoidal components, one wave period from which having multiple frequency of its fundamental frequency one, leading to electrical power quality problems. Harmonic distortion in term of voltage and current ones, generally is due to non linier impedance. Energy saving lamp is one of example of it. This research was done by performing studies in harmonic voltage and harmonic current from four different brands of energy saving lamp having power rating of 8 watt, 16 watt, and 20 watt and uses IEEE Standard of 519-1992 as a reference in determining maximum limitation voltage and current harmonics. The result of the tests were showed that total harmonic distortion (THD) voltage at each different brand of energy saving lamp having power rating of 8 watt, 16 watt, and 20 watt did not exceed the IEEE 519-1992 maximum limitation of 5%. While total harmonic distortion (THD) current at each different brand of energy saving lamp having power rating of 8 watt, 16 watt, and 20 watt had exceed result range exceeding 71,2%.]]>

<![CDATA[Teknik steganografi BPCS (Bit-Plane Complexity Segmentation) merupakan salah satu teknik steganografi yang cukup baru. Salah satu proses penting dalam Teknik Steganografi BPCS adalah proses penghitungan nilai kompleksitas suatu bit-plane. Nilai kompleksitas dihitung dengan melihat seberapa banyak pergantian bit yang terdapat dalam sebuah bit-plane. Jika bit-plane tersebut memiliki nilai kompleksitas yang tinggi, maka bi-plane tersebut dikategorikan sebagai bit-plane noise yang tidak mengandung informasi yang berharga pada gambar. Klasifikasi bit-plane yang menggunakan himpunan cripst (noise dan tidak) tersebut tidak adil, dimana sebuah perbedaaan nilai yang sedikit saja akan mengubah secara signifikan status dari bit-plane tersebut. Penelitian ini mencoba untuk menerapkan prinsip himpunan fuzzy untuk mengklasifikasikan bit-plane menjadi kedalam tiga buah himpunan yaitu informatif, informatif sebagian, dan noise region. Klasifikasi bit-plane kedalam himpunan fuzzy terebut diharapkan dapat menggolongkan bit-plane secara lebih objektif dan pada akhirnya daya tampung gambar terhadap pesan dapat ditingkatkan dengan dengan menggunakan inferensi fuzzy mamdani untuk mengambil keputusan bit-plane mana yang akan digantikan dengan pesan berdasarkan klasfikasi bit-plane yang tersedia dan ukuran pesan yang akan disisipkan.]]>
