Abstract

Abstrak LTE merupakan teknologi evolusi dari GSM yang dikembangkan oleh 3GPP dan disebut sebagai salah satu teknologi pra-generasi keempat (4G). Implementasi LTE di Indonesia sendiri masih belum menyuluruh dan baru diterapkan di beberapa kota besar saja, namun frekuensi untuk menggelar LTE sudah disediakan, salah satunya pada frekuensi 1800 MHz. Sebelum menggelar teknologi LTE perlu dilakukan perencanaan jaringan untuk mengetahui jumlah eNodeB yang dibutuhkan. Pada Tugas Akhir ini dilakukan perencanaan jaringan LTE FDD 1800 MHz menggunakan perangkat lunak Atoll. Perencanaan yang dilakukan menggunakan metode perencanaan cakupan dengan studi kasus di Kota Semarang. Untuk mendukung hal tersebut ditentukan model propagasi yang sesuai untuk perencanaan ini, yaitu model COST-231 Hata. Hasil dari simulasi menunjukkan bahwa jumlah eNodeB yang dibutuhkan dalam perencanaan adalah sebanyak 152 site dan 453 sel agar area Kota Semarang tercakupi oleh RS dan SINR minimal sekurang-kurangnya 95%. Hasil lain didapatkan bahwa jumlah pelanggan yang dapat mengakses jaringan hingga ke daerah indoor didapatkan sebanyak 98,7% untuk bandwidth 5 MHz, 97,1% untuk 10 MHz, 95,9% untuk 15 MHz, dan 94,8% untuk 20 MHz. Pada bandwidth 20 MHz kapasitas sel dan throughput sel yang dihasilkan adalah yang paling besar dengan beban sel sebesar 50,53% untuk downlink dan 18,84% untuk uplink, dan throughput sel yang dihasilkan sebesar 34.633 kbps untuk downlink dan 9.591 kbps untuk uplink. Kata kunci: LTE, perencanaan cakupan,  Atoll  Abstract LTE is technology evolution of GSM that developed by 3GPP as one the 4G technology.

Abstract

Tujuan artikel ini adalah menjelaskan perang gender yang tercermin dalam novel karya pengarang- pengarang perempuan Indonesia dari generasi Ayu Utami. Perang gender adalah ?dendam abadi? pengarang-pengarang perempuan terhadap pengarang laki-laki yang, sampai sekarang, mengeksploitasi tubuh perempuan dengan besar-besaran dan memaksa mereka untuk membaca tubuhnya sendiri dari sudut pandang laki-laki. Melalui teks erotis sebagai bahasa ekspresi, pengarang perempuan mampu menulis tubuh mereka dengan sudut pandangnya sendiri. Abstract: This paper has the objective of explaining the gender struggle implied in the novels of Indonesian female authors of Ayu Utami generation. The gender struggle is female author?s ?eternal enmity? towards male authors who, up till now, have greatly exploited woman?s body and force them to read their own body from the male point of view. Through erotic texts as the language of expression, female authors are able to write their body with their own point of view. Keywords: gender struggle, female authors, Ayu Utami generation

Abstract

This paper presents the analyzed Monopole Antenna for Ultrawideband with a rectangular patch design using bevel technique at a frequency of 3.1 – 10.6 GHz. The fabricated antennas with dual bevel angles have a very compact width and length of 40 mm x 33 mm respectively and a groundplane width of 13 mm. To get bandwidth improvement on monopole antennas can be applied to the bevel angle on the patch. So, to get the best antenna design, 3 optimizations of antenna size changes were carried out during the simulation, that is optimization of patch length, patch width and bevel angle. Variation of patch length and width is used to change the frequency range and variation of bevel angle to increase bandwidth. From each change, the best result is taken. The experiment obtained the best simulation result of antenna and then fabricate it. From the measurement results on the fabricated antenna, the lowest S11 value is -24.6 dB, gain 2.6 dBi at a frequency of 5 GHz and radiation pattern is omnidirectional. The optimization process using the bevel technique has been proven to be successful in shifting the frequency range by around 600 MHz and increasing the bandwidth by about 4% or 30 MHz.

Abstract

The requirement of wireless access networks and user equipments to support coexistence of many communication standards and frequency bands poses challenge on antenna to be broadband and small. The application of half-cut technique to broadband printed monopole with microstrip feeding worsens the resulted antenna’s impedance. To improve the half-cut antenna impedance mathing, two methods were investigated in this paper: (1) monopole and ground extension, (2) the application of microstrip line transformer and ground extension. The first approach only produces limited improvement, whereas method #2 can enhance the return loss significantly. The application of the second approach potentially produces antenna pair that has low mutual coupling, good return loss, and small size. Considering its radiation pattern, the antenna is suitable for diversity and MIMO. Its application in broadband microwave-photonic access point need special arrangement due to radiation null at 5 GHz band at right side.DOI:http://dx.doi.org/10.11591/ijece.v3i5.3376

Abstract

The recent progress of dimension scaling of electronic device into nano scale has motivated the invention of alternative materials and structures. One new device that shows great potential to prolong the scaling is junctionless FET (JLFET). In contrast to conventional MOSFETs, JLFET does not require steep junction for source and drain. The device processing directly influence the performance, therefore it is crucial to understand the role of gate processing in JLFET. This paper investigates the influence of gate material and process on subthreshold performance of junctionless FET, by comparing four sets of gate properties and process techniques. The result shows that in terms of subthreshold slope, JLFET approaches near ideal value of 60 mV/decade, which is superior than the SOI FET for similar doping rate. On the other hand, the threshold value shows different tendencies between those types of device.

Abstract

Non-planar structures have been identified as promising structure for next device generation in the nanoelectronic era. However, the continuous device dimension scaling into nano regime eventually requires more sophisticated model due to the limitation of the existing models. A model for non-planar MOSFET structure was elaborated in this paper, especially for device with pillar structure, using analytical approach. The concern of channel shape and structure were discussed as well. The result shows the shift in subthreshold characteristic in the channel with recessed channel model. The charge sharing is suspected as one of the key parameter in the shift of performance in the recessed region.
