Ikhsan Assiddiq U.P. masagus162181001@std.trisakti.ac.id Syah Alam syah.alam@trisakti.ac.id Indra Surjati indra@trisakti.ac.id <p>Polar code has been proven to obtain Shannon capacity for Binary Input Discrete Memoryless Channel (BIDMC) and its use has been proposed as the channel coding in 5G technology.&nbsp; However, its performance is limited finite block length, compared to Turbo or LDPC codes.&nbsp; This research proposes the use of various CRC codes to complement Polar codes and analyses the performance based on Block Error Rate (BLER) to <em>E<sub>s</sub>/N</em><sub>0</sub> (dB).&nbsp; The CRC codes used are of degrees 11 and 24, with 3 different polynomial generators for each degree. The number of bits in the information sequence is 32. The list sizes used are 1, 2, 4, and 8. Simulation results show that the concatenation of CRC and Polar codes will yield good BLER vs E<sub>s</sub>/N<sub>0 </sub>performance for short blocks of codeword, with rates 32/864 and 54/864. &nbsp;Concatenating CRC codes with Polar codes will yield a BLER performance of 10<sup>-2</sup> with E<sub>s</sub>/N<sub>0</sub> values of -9 to -7 dB when CRC codes of degree 11 is used, depending on the SC list used. The use of CRC codes of degree 24 enables a BLER performance of 10<sup>-2</sup> with E<sub>s</sub>/N<sub>0</sub> values of -7 to -6 dB when the SC list used is 1 or 2.&nbsp; The use of CRC codes of degree 24 combined with SC list with sizes 4 or 8 will improve the BLER performance to 10<sup>-2</sup> with E<sub>s</sub>/N<sub>0</sub> values of -8 to -7.5 dB.</p> 2020-09-27T00:00:00+00:00 ##submission.copyrightStatement## https://ejournal.st3telkom.ac.id/index.php/infotel/article/view/475 Evaluation of the e-Learning Utilization as a Learning System in Higher Education Institution 2020-09-27T12:20:49+00:00 uswatun hasanah uswatun@stmikbumigora.a.c.id <p>E-learning has been applied to support the effectiveness of learning activities at STMIK BumigoraMataram. But in reality, its utilization is still not optimal. This is based on the very low number of its active users. Meanwhile, an evaluation of the problem has also not been carried out. Evaluation of the use of e-learning is formulated into a model based on the TAM (Technology Acceptance Model) model, while SEM (Structural Equation Modelling) is used for analysis. Based on the measurement analysis in this study, it was found several factors that most influenced the effectiveness of the implementation of e-learning, namely the usage tutorial for users, ICT facilities related to the Ease of accessing the internet network. While the structural analysis, it was discovered, factors attitude towards the use and perception of usefulness is strongly correlated to the actual use factors. Mean, the actual use is a real condition of the use of e-learning measured by the frequency and duration of time in the use of the technology which is influenced by the user's belief in accepting the existence of e-learning in STMIK Bumigora and user beliefs related to the benefits when using it. Therefore, attitudes toward the use and perception of usefulness are the main determining factors in measuring the frequency and duration of time of e-learning use.</p> 2020-09-27T12:20:49+00:00 ##submission.copyrightStatement##
