Abstract

Abstract—Decision Support Systems help decision making to solve very unstructured problems and complex. Every decision-making process always results in one final choice. In the application of decision support systems often use the Analytical Hierarchy Process (AHP) method. AHP can solve complex problems where many criteria are taken. In addition to the application of DSS, the authors also analyze the effect of implementing Decision Support Systems in an institution using simple linear regression. Simple linear regression is used to determine the effect of independent variables on the dependent variable. From several research reviews in Indonesia, many have applied the Analytical Hierarchy Process (AHP) method to assist in the decision support process. These institutions / organizations are active, in the fields of Academic, Private, Hospital, Tourism, and Government. This study found the results of the evaluation of the desktop-based AHP system development to be the most dominant with a figure of 58% where in government projects the largest was 48%. Keywords: Decision Support Systems, Analytical Hierarchy Process, AHP, Information System, Simple linear regression.

Abstract

The combination OFDM (orthogonal frequency division multiplexing), and pulse shaping are expected to reduce the effects of Inter Carrier Interference (ICI) and error occurred. This study aimed to compare the performance of OFDM without pulse shaping nd OFDM with pulse shaping Improved Sinc Power (ISP) pulse through Frequency Selective Fading channel, in terms of BER (bit error rate) vs. Eb/No (energy per bit to noise power spectral density ratio). This study implemented simulation using Matlab R2018a. The results of the simulation OFDM with ISP pulse system performance has better results than OFDM without pulse shaping. In the transmission Frequency Selective Fading channel, to reach 10-1 BER value in OFDM with ISP pulse was required Eb/No of 2 dB. While the OFDM without pulse shaping systems required Eb/No 10 dB. Keywords — OFDM, Pulse Shaping, ICI, ISP pulse, Frequency Selective Fading.

Abstract

Sebagian besar masyarakat Bali mampu berkomunikasi menggunakan bahasa Bali, akan tetapi hanya sedikit orang Bali yang mampu dan mengerti tata penulisan Aksara Bali. Hal ini terjadi karena tata cara penulisan Aksara Bali aturannya cukup kompleks. Diperlukan cara-cara yang inovatif untuk menarik minat masyarakat dalam mempelajari Aksara Bali, salah satunya dengan memanfaatkan teknologi informasi. Penelitian ini membahas desain perangkat lunak SMS dengan translasi text Aksara Bali. Dalam pembuatan desain perangkat lunak ini terdiri dari beberapa tahapan, yaitu: pengumpulan data dan literatur, identifikasi permasalahan, desain dan perancangan sistem, serta implementasi dan pengujian. Hasil desain translasi text Aksara Bali pada perangkat lunak SMS berupa: perancangan proses translasi text Aksara Bali, perancangan proses pegiriman SMS, dan perancangan proses penerimaan SMS. Sedangkan desain antar muka translasi text Aksara Bali pada perangkat lunak SMS berupa desain antarmuka pengiriman dan penerimaan SMS.

Abstract

CDMA technique has been successfully employed to implement high capacity mobile networks with optimum channel bandwidth utilization. The two most coveted criteria for the spreading codes used in such network are, the number of codes in the set and the code orthogonality, in order to ensure accommodation of large number of users and as well as minimal interference between the users. Walsh code has proved to be a popular orthogonal code, whereas m-sequence, Gold code and Kasami code have established themselves as popular non-orthogonal binary codes. Small set Orthogonal Kasami code has been proposed and evaluated by researchers for CDMA applications. In this paper the authors report the design of hybrid orthogonal large set (HOLS) code for synchronous CDMA systems. The HOLS code was evaluated in a synchronous CDMA system over different channel conditions. The authors also demonstrate that the BER performance of the HOLS code is comparable to that of the existing orthogonal codes, but outperforms Gold and large set Kasami code sequences. The HOLS code sequence is also shown to outperform the existing code sequences in the number of cells it can support. In terms of multiple access interference (MAI), the cross-correlation function (CCF) of the HOLS code sequence is comparable to that of Walsh and orthogonal small set Kasami codes, and much better than those of Gold and large set Kasami code sequences. HOLS code sequence has comparable auto-correlation function (ACF) with that of Gold, large set Kasami and orthogonal small set Kasami code sequences and a much better ACF than that of Walsh code sequence.

Abstract

Access to intranet and internet networks in the campus area requires a number of Wi-Fi devices to cover the coverage area of Udayana University. The Wi-Fi service is expected to be used for VoIP applications in the context of wireless communications. The IEEE 802.11g standard specifies an outdoor service range of 140 m and an indoor service range of 38 m. From research conducted in the engineering faculty area, the quality of VoIP service uses Wi-Fi with range of 25 m. In this research, the design of Udayana University campus Wi-Fi needs using Atoll application with IEEE802.11g standard at 140 m, 38m and 25m ranges. The results obtained to cover Udayana University campus area require Wi-Fis: 7 units for range 140 m, 98 units for range of 38 m and 225 units for range of 25 m

Abstract

The characteristics of wireless channel are determined by multipath propagation. The transmitted signal will be scattered so that it produces fading. Fading influenced by multipath component will cause delay spread which damages the signal. Thus, spread spectrum technology is used by using a bandwidth that is greater than the original signal. The objective of this study was to determine the effect of the number of multipath components on orthogonal variable spreading factor (OVSF) codes on multipath fading channels viewed from values and Bit Error Rate (BER) graphs versus Energy Bits per Noise (Eb/No). This study would compare the performance of OVSF code communication system on multipath channels by varying multipath components of 4, 8, 12, 16 and the length of OVSF codes used of 16, 8 and 4. The simulation results showed an increase in BER values when the number of multipath components was added. The more the number of multipath components used, the more the number of reflected signals that will interfere with the desired signal in the receiver. The length of the OVSF code influences the performance of the OVSF code on the multipath fading channel, because each code has a different processing gain value that is affected by the length of the code used
