Abstract

By increasing of users/devices number, Coded Random Access mechanism is suitable to enable successful access wireless successfully on super dense network. Problem of using Coded Random Access is stopping set appears. Stopping set is a harmful structure, where no other way for some trapped users in a set to be decoded. Stopping set is affected by degree distribution. This paper presents probability experiment of stopping set on Coded Random Access for Internet of Thing (IoT). It uses MATLAB R2016a as tool proving. The result of this research is used as performance networking prediction of future IoT. The results confirm that this research has a highly accuracy opportunity and becomes so practical. Then, a new graph stopping set is found on the result of simulation. The number of user/device randperm, ˄(x) and G affect the probability of stopping set on CRA for IoT network. More G approaches 1, the more number of stopping sets too appear and vice versa. For probability of stopping set on Coded Random Access, if G more keeps from 1, so occetence of stopping set on CRA prpbability is smaller. On the other side, if G gets closer to 1, so appearance of stopping set on CRA, probability is bigger.Keyword : Super Dense-Network, Coded Random Access, Stopping Set.

Abstract

Sistem LTE dan EGSM dalam Alokasi frekuensi di Indonesia berada pada spektrum frekuensi yang berdekatan. Hal ini berpotensi menyebabkan terjadinya gangguan interferensi antara kedua sistem. Penelitian ini berfokus pada meminimalisasi interferensi antara downlink LTE(base station LTE sebagai interferer) terhadap uplink EGSM (base station EGSM sebagai korban interferensi) menggunakan teknik pemisahan kanal. Interferensi ini berpotensi menurunkan kualitas penerimaan sinyal pada base station EGSM. Pada penelitian ini dilakukan analisa untuk mengetahui potensi adanya interferensi antara sistem LTE dan EGSM pada pita frekuensi 800 MHz dengan melakukan simulasi menggunakan software SEAMCAT. Hasil yang diperoleh untuk menghilangkan interferensi yang terjadi pada sistem LTE dan EGSM adalah dengan penambahan guard band, dengan jarak terbaik didapatkan pada jarak 4 km dengan tingkat C / I  ≥12 dB pada zona lingkungan URBAN dan jarak 5 km pada lingkungan zona SUB URBAN

Abstract

Microstrip Antenna is widely developed and used in modern telecommunications equipment because of its advantages. Microstrip antenna is also used in 5G development which is expected to increase communication capacity and also be able to provide very large data rates. The frequency used in 5G is 28, 38, and 78 GHz. However, the 5G network with high frequency has a weakness: transmitted waves are vulnerable to weather because of their dense waveform. Therefore, the multiband is used to support different frequencies in one antenna. Furthermore, antenna reconfiguration is used to set the antenna to work on a different frequency and adjust different radiation patterns depending on the needs without changing the form of the antenna. This paper proposes the dual-band frequency reconfigurable antenna with RT Duroid 5880 as its substrate using PIN diodes placed between the main patch and secondary patch element and simulated on CST software for 28 GHz and 38 GHz with two conditions, ON and OFF. Both simulated and measured results show that the antenna can work well as intended. During the OFF condition, the antenna only works at 38 GHz, while in the ON condition, the antenna works at 28 GHz and 38 GHz, respectively.

Abstract

Brain is the important part as a control center, coordination and controling the human body. Inside the brain can be noticed that there are activity and abnormalities of the brain work. Every single person has activity or abnormalities brain work. It can happen to children with autism. Children who have an autistic symptoms occur due to distrubance of complex and variation of the brain function. A brain waves recorder or Elektroesefalogram can see and read the brain work activity. elektroesefalogram is a test that is used to know the electrical activity of the brain to detect whether there is a brain abnormality or not. This research designs a prototype EEG equipment especially to record children with autistic symptoms. The choosen participants in this research are chosen by seeing the result of CAST questionnaire that contains 37 questions. The recording in this research is used by using a particular sensor which is electrode, that is installed on the scalp and connected to computer/laptop. Using 4 electrodes in the lobes that are determined as a benchmark. The result of the recording can be displayed directly by MATLAB on a connected computer.Keywords : Autism, EEG, CAST, electrodes, Electroensephalogram, MATLAB.

Abstract

One part of forensic anthropology involves investigating skeletal remains to identify corpses, and many of these remains were found incomplete, burned, broken, or destroyed, making investigation challenging. This study aims to use the pelvis and femur to identify the gender of skeletal remains. The pelvis and femur have previously been proven to be accurate indicators of a corpse's gender. The identification process is done through the measurement of the subpubic angle of the pelvis and the angle taken straight down from the top of the femur to the patella and then straight up. The two measurements were combined using the principal component analysis (PCA) method into two attributes on the x and y axes. These attributes were later used as data for the machine learning model design. The design process consisted of an Artificial Neutral Network (ANN) design model and Support Vector Machine (SVM) design model combined into a hybrid machine learning system. The ANN and SVM hybrid machine learning were tested with acquired data. The result of the test using the confusion matrix showed 83.33% accuracy, which is categorized as "good classification" based on Area Under the Curve (AUC).

Abstract

As one of the processes of patient care, diagnosis, and monitoring are the most important steps in the medical field. Sleep apnea is a problem that affects about 25 million Americans, and 80% of them go untreated because it is not identified. Monitoring has a big role in making patient treatment decisions. So this research aims to produce a wearable resonator mask that can work as a breathing rate monitor. The proposed resonator will use the relative humidity generated during the respiration process. The resonator uses a textile jeans material that is flexible, comfortable, and fits on a mask. Testing is carried out in 3 different positions; lying down, sitting, and standing. There is a difference in the percentage of RH produced from each position based on the difference in the frequency range produced. The proposed resonator operates well at 3.9 GHz.

Abstract

Due to the advancement of telecommunication platform, users are now demanding high performance application. Propagation models play a vital role in the characterization and design of wireless and mobile communications networks. However, if they are utilized in a different environment than the one they were formulated for, propagation path-loss models may produce unacceptable deviation in predictions. Nowadays every mobile service provider continues to build a telecommunications tower with little regard for its impact on the area function. This paper presents the cellular network planning in the district of Bukit Raya, Pekanbaru. From the field survey, there are found sixty-two (62) cell sites. This number is extremely large compared to the calculated one. From the theory, only twenty-five (25) cell sites are required. Thus, it was found inappropriate deployment cell sites.

Abstract

Nowadays, most antenna researchers over the world are focusing on the design of the antenna for the fifth generation (5G) application (indoor and outdoor). High intensive research on 60 GHz antenna for high data rate indoor communication is becoming a trending topic. The high propagation loss at this band is the most challenging. The antenna needs to have higher gain to overcome the loss. Such antenna designs have been proposed recently. This paper, a new MIMO 2x4 patch rectangular antenna operating at 60 GHz is designed for Wi-Gig application. The rectangular patch antenna has 1.75 mm x 1.54 mm of size, printed on Rogers Duroid RT 5880 substrate, the dielectric constant of 2.20 and loss tangent of 0,0009. The antenna was designed and simulated using CST simulation software. The simulated return loss showed a very consistent characteristic. The return loss reached −30 dB at 60 GHz. The broad bandwidth obtained is 4.3 GHz concerning -10 dB. The omnidirectional radiation pattern with 13.4 dBi of gain is obtained. This antenna meets the Wi-Gig requirement.
