Abstract

ABSTRACT The design has meaning and value. It is not only point out to the object but also refers to the dif- ference meaning contained. The design has a variety of meanings therefore no singular definition will suffice to explain the whole process in design. Design can refer to the knowledge, work and discourse. The process of creating a design in that sense requires consideration of aspects of unity between form, function, meaning and value. Along with the development of science, technology, art and culture, they expanded the meaning of design started by the issues of form into value that ultimately relates to identity. Through literature study of design works from some types of products in a particular period, that every country that has its roots in traditional design were not uniform in defining or classifying designs. A variety of meanings of the design can be determined design position in tradition activities, and actualize it in a different national identity. Keywords: Education of Art, Design, Tradition, Value and Identity    ABSTRAK Desain memiliki makna dan nilai, tidak hanya mengacu pada objek tetapi perbedaan mak- na yang dikandungnya. Desain memiliki beragam arti, karenanya definisi tunggal tidak akan cukup menjelaskan seluruh proses dalam desain. Desain dapat mengacu kepada ilmu, karya maupun wacana. Proses membuat desain dalam pengertian tersebut, membutuhkan pertim- bangan aspek kesatuan antara bentuk, fungsi, makna dan nilai. Seiring perkembangan ilmu pengetahuan, teknologi, seni dan budaya, desain mengalami perluasan makna dari persoalan bentuk menjadi persoalan nilai yang pada akhirnya berkaitan dengan identitas. Melalui studi literatur karya-karya desain dari beberapa jenis produk pada masa tertentu, bahwa setiap Ne- gara yang memiliki akar dalam tradisi desain, tidak seragam dalam menentukan atau mem- buat klasifikasi desain. Dari keragaman pemaknaan terhadap desain, dapat ditentukan posisi desain dalam aktivitas tradisi, serta mewujudkannya dalam identitas nasional yang berbeda. Kata kunci: Pendidikan seni, Desain, Tradisi, Nilai dan Identitas

Abstract

Abstrak Wireless LAN adalah suatu teknologi nirkabel yang berbasis OFDM (Orthogonal Frequency Division Multiplexing) dan MIMO (Mutiple Input Multiple Output) yang dapat digunakan untuk komunikasi data. Peningkatan permintaan pengguna sistem Wireless LAN juga menyebabkan peningkatan pengembangan Wireless LAN. Standard dari Wireless LAN adalah IEEE802.11a/b/g dan IEEE802.11n yang menggunakan teknik OFDM dan MIMO untuk meningkatan laju data tanpa memerlukan tambahan bandwidth. Tujuan dari paper ini adalah untuk mengimplementasikan algoritma deteksi Sphere pada simulator WLAN 802.11n pada bagian MIMO blok decoder. Parameter yang diamati adalah nilai BER vs SNR (signal to Noise Ratio). Hasil yang diharapakan adalah kinerja yang lebih baik dibandingkan dengan algoritma deteksi linear (MMSE, ZF) dan algoritma deteksi optimal, MLD. Pada MCS 13 untuk nilai BER 10-4, hasil simulasi menunjukkan bahwa metode ZF, MMSE, MLD dan SD mencapainya pada SNR 44 dB, 42 dB, 31 dB dan 33 dB. Sedangkan pada MCS 14, keempat metode mencapai nilai BER 10-4 pada SNR 46 dB, 44 dB, 31 dB dan 33 dB. Dan pada MCS 15 akan mencapai nilai BER 10-4 pada SNR 55 dB, 53 dB, 36,5 dB dan 39,5 dB. Dibandingkan dengan MLD, algoritma deteksi Sphere akan bernilai lebih besar tetapi dengan kompleksitas yang lebih sedikit. Kata Kunci : WLAN 802.11n, MIMO, OFDM, decoding, Sphere Detektor, BER

Abstract

Abstrak   Teknologi sel femto pada LTE (Long Term Evolution) dapat meningkatkan kualitas sinyal di dalam ruangan karena penempatan stasiun pemancar sel femto yang berada di dalam ruangan. Dengan berkurangnya jarak antara stasiun pemancar, dalam hal ini yaitu FAP (Femtocell Access Point) dengan UE (User Equipment) maka kualitas sinyal di dalam ruangan diharapkan membaik. Namun, dengan digunakannya sel femto, timbul fenomena interferens antara sel makro dan sel femto, juga interferens antar sel femto.Kualitas sinyal (SINR) pada pengguna (downlink) baik dari sel femto atau sel makro akan dikaji berdasarkan perhitungan link budget dengan memperhitungkan fenomena interferens yang mungkin terjadi menggunakan perangkat lunak LabView2009. Dari hasil simulasi rugi propagasi indoor sel femto  memiliki nilai yang lebih rendah dari sel makro sebesar  85,8137dB sedangkan sel makro 144,4035dB. Nilai SINR sel femto downlink ketika tidak ada pengaruh dari sel makro, nilai SINR maksimum adalah 36,0838 dB dan nilai SINR terkecil adalah 20,0865 dB dan ketika terdapat sebuah sel makro dan FAP yang melayani pengguna berada di ruang lingkup sel makro tersebut maka nilai SINR terbesar menjadi hanya 23,3947 dB sedangkan SINR terkecil adalah 20,0863dB.   Kata kunci: femtocell, LTE, link budget, interferens, SINR. Abstract Femtocell LTE (Long Term Evolution) technology can increase signal coverage at indoor environment because the deployment of the femtocell base station is in the building. With a distance reducement between a femtocell base station (usually called FAP, Femtocell Access Point) with a user equipment (UE), the signal quality hopefully will be better. But, the deployment of femtocell emerges interference phenomenon between macrocell and femtocell, also interference between femtocells itself.Quality cues (SINR) at the user (downlink) from both femto cell or macro cell will be assessed by taking into account the link budget calculation possible interference phenomena using software LabView2009. From the results of simulations of indoor propagation loss femto cells have a lower value than the macro cells at 85.8137 144.4035 dB dB while the macro cell. Value SINR downlink femto cell when there is no influence of the macro cell, the maximum value is 36.0838 dB SINR and SINR value and the smallest is 20.0865 dB when there is a macro cell and FAP serving users are in the scope of the macro cell, the value SINR largest being only 23.3947 dB while the smallest SINR is 20.0863 dB.   Keywords: femtocell, LTE, link budget, interfernce, SINR.

Abstract

Wireless LAN is wireless technology that can be used for voice and data communication. The increase of user requirement in Wireless LAN system caused the development of Wireless LAN increasing too. Standard of Wireless LAN is IEEE802.11a/b/g and IEEE802.11n use OFDM and MIMO technique for increase data rate without additional bandwidth. The purpose of this final project is to design physical layer of transmitter wireless LAN system to obtain gigabit throughput. Wireless LAN that we used now can produce rate up to 600 Mbps. So we expect this design of wireless system can increase data rate into gigabit throughput. The design of this system organized from arrangement of block diagram into preamble and data field. The data field, same as the previous standard, 802.11n consists of block scrambler, encoder parser, FEC encoder, interleaving, constellation mapper, spatial mapper, IFFT, cyclic shift, guard interval inserter and windowing. Whereas the preamble consists of legacy preamble is L-STF, L-LTF and L-SIG that have same format with previous standard in order to the output of transmitter 802.11ac can be compatible to 802.11a/n. Then, very high throughput preamble is added to this system as a preamble for 802.11ac. From the experiment result, we get the conclusion that wireless LAN 802.11ac is formed based on the previous standard 802.11a and 802.11n which have same frequency 5 GHz. Then, for 802.11ac we duplicate bandwidth from 40 MHz to 80 MHz and apply phase rotation. For the software verification backward compatibility, we determine the parameters 100 iteration, use MCS (Modulation Coding Scheme) 64-QAM and 4 transmit antenna. As the result the 802.11ac transmitter can be recognized by 802.11a/n receiver and it can be shown as decreasing of SIG Error rate for SNR range 0-20 dB.

Abstract

Since Hertz and Marconi, antennas have became increasingly important to our society until now they are indispensable. They are everywhere: at home and workplaces, on cars and aircraft, also in ships and satellites. So far most used antenna is an antenna with a single polarization, the horizontal polarization or vertical polarization only. The advantage of circular polarization is the radiation of antenna can be well received by the vertical receiving antenna or horizontal receiving antenna. The purpose of this research is to design and build a circular polarized antenna. Then the values of the parameters measured using Hewlett Packard 8656B Signal Generator as a transmitter and Hewlett Packard 8901A Modulation Analyzer as a receiver. Both measuring devices were used to determine the frequency and power generated by the antenna. SX-1000 SWR meter as a measuring VSWR and analog VU meters are used to determine the signal strength of the antenna. The result shows that the antenna works well on a predetermined frequency (144 MHz), has omni directional radiation pattern and its VSWR is 1.09. The result of the antenna radiation can also be well received, using vertical and horizontal polarization antenna. VU meter shows that the highest value when antenna used as transmitter is 10 μV and 11 μV when antenna is used as receiver antenna. Keywords: Antenna, vertical polarization, horizontal polarization, circular polarization.

Abstract

Breast cancer is the most common kind of cancer suffered by women. Mammography has been a common method for early detection of breast cancer. Recently mammograms are examined manually, so it demands good knowledge, intuition, and experience in this particular field. In many cases the breast normal tissue can hide malignant so that it can’t b seen on the mammogram. With image processing tissue into mammogram image can be effored to know location. Much methode are used in digital image processing. Methode is used in this final task is texture analysis. Based on that methode, this simulation program is made for identification tissue into mammogram image using wavelet Haar methode. Data about mammogram image any 42 image are get from Telogorejo Hospital Semarang. This program simulation is started with reading image processing and then continued to ROI (region of interest) process, in image from ROI used image enhancement quality with median filter to strech the contrast, after that texture analysis is used to get coefficient from that image. The classification is started with the decomposition process to obtain the wavelet coefficients which then counted the energy and entropy values of each images and then incorporated to database. The next process is comparing the energy and entropy between images which will be classified with the images on the database. The final step is to find Euclidean distance to show that the tested images is one of the class on the database. From the 42 sample observed, the testing result image after ROI and enhancement show that it has recognition rate 86% and testing result without image enhancement show recognition rate at 50%. The observed with using image enhancement ang wavelet Haar from 14 normally image, 13 image can identified, from 20 masses image, 15 can identified, from 8 microclasification image, 7 can identified. The observed without image enhancement and wavelet Haar is using 10 image analyzed by doctor. from 2 normally image, 1 image can identified, from 6 masses image, 2 can identified, from 2 microclasification image, 2 can be identified as microclassification.

Abstract

Provision of broadband communications services in High Altitude Platform Station (HAPS) is a new idea and worthy to be discussed. One is the application of OFDM transmission technique as a medium for digital modulation in HAPS. HAPS is a new technology in the telecommunications sector at an altitude of 18-50 km (the stratosphere) and used to serve the broadband wireless access (BWA) and other multimedia devices. HAPS technology has advantages that can cover the lack of terrestrial and satellite technology. Performance of OFDM transmission technique in which a HAPS channel Rician channel can be evaluated by looking at the effect of K-factor. K-factor is the dominant signal power ratio (Line Of Sight) with multipath signal power. In real conditions on the ground, the received power is a combination of the dominant signal power and multipath signal power. The increase in elevation angle between the HAPS platform with user terminals resulted in the increasing value of K-factor and the influence that affected the performance of OFDM systems multipath fading. Effect of K-factor can be identified by computer simulation. Effect of K-factor observed by looking at the value of Bit Error Rate (BER) on the system to the value of signal to noise ratio (SNR) by varying the bitrate and frequency doppler. The results showed that the increasing value of K-factor at the same bitrate the smaller the resulting BER. This shows the better performance of OFDM systems. Meanwhile, the OFDM system performance deteriorated over increasing Doppler frequency. This is because the increasing value of K-factor at the same Doppler frequency resulting more BER value. Keywords: HAPS, OFDM, K-factor, BER, bit rate, Doppler frequency.
