Abstract

Tujuan dari penelitian ini adalah untuk menganalisis penerimaan user pada sistem informasi rumah sakit dengan menggunakan variabel Kegunaan yang Dirasakan (Perceived Usefullness), kemudahan yang dirasakan (Percieved Ease of Use) dan variabel sikap pengguna (Atittute toward Using) yang ada pada TAM (Technology Acceptance Model). Sampel pada penelitian ini berjumlah 66 responden. Data diperoleh menggunakan kuesioner yang telah diuji validitas dan reliabilitasnya, kemudian dianalisis dengan teknik regresi linier berganda. Hasil analisis persamaan regresi ke-1 menunjukkan variabel Perceived Usefullness (X1) memiliki pengaruh signifikan terhadap variabel Attitute toward Using (Y) dengan t hitung sebesar 6,551 dengan signifikansi p = 0,000 (<0,05). Variabel Percieved Ease of Use (X2) berpengaruh signifikan terhadap variabel Attitute toward Using (Y) dengan t hitung 1,988 dengan signifikan p = 0,011(<0,05). Hasil analisis persamaan regresi ke-2 menunjukkan bahwa variabel X1 dan X2 secara bersama-sama berpengaruh signifikan terhadap Attitute toward Using (Y) karena nilai statistik F Hitung = 59,712 dengan signifikansi p = 0,000(<0,05).Kata Kunci — Sistem informasi, Perceived Usefulness, Perceived Ease of Use, Attitude Toward Using, TAMThe purpose of this study is to analyze user acceptance in hospital information systems using Perceived Usefulness, Perceived Ease of Use, and Atittute toward Using variables in TAM (Technology Acceptance). Model). The sample in this study amounted to 66 respondents. Data obtained using questionnaires that have been tested for validity and reliability, then analyzed by multiple linear regression techniques. The results of the analysis of the 1st regression equation show that the Perceived Usefulness variable (X1) has a significant influence on the Attitute toward Using (Y) variable with t count of 6.551 with significance p = 0.000 (<0.05). The variable Percieved Ease of Use (X2) has a significant effect on the Attitute toward Using (Y) variable with t count 1.988 with a significant p = 0.011 (<0.05). The results of the analysis of the second regression equation show that variables X1 and X2 together have a significant effect on Attitute toward Using (Y) because the statistical value F count = 59.712 with significance p = 0.000 (<0.05).Keywords — Information System, Perceived Usefulness, Perceived Ease of Use, Attitude Toward Using, TAM

Abstract

the number of motorized vehicles increases every year, especially private vehicles and is not offset by inadequate access until the road becomes more crowded, even traffic jams occur, especially during public holidays and national holidays. for example, during eid holidays there is a density of traffic flow when going back and forth every year, with the development of current technology the density of traffic flows that occur can be calculated so that it will be easier to anticipate in the future. but in this study only will examine the parameter values that cause the vehicle to occur density and accumulation, because it can be developed with parameter values so that the results can be obtained efficiently in solving traffic density. From the results of the anfis method, efficiency is obtained, namely on h-1 and h days of 2014, and 2017 can use Parameters with magins of 6,3% and 4,32%, while 2015 and 2016 can use parameters with margins 1,79% and 0,79%. and for the h + 1 day of 2014, 2016, and 2017, it is more efficient to use parameters with margins 1,4% and only parameters in 2015 which have the efficiency value using parameters with margin -6,17. anfis application in this calculation can be developed in a prediction system.

Abstract

The development of communication is increasingly rapid which does not escape from various threats such as eavesdropping or data theft, because that security aspect of data security is now very calculated. Various ways have been done to secure data that contains confidential information. One method used is to scramble the data into unclear content, so that when tapped it will be difficult to find out the actual information content. Encryption techniques by changing and randomizing the original form of data are called cryptography. Vigenere cipher is one type of classical cryptography algorithm that is popular and often used. This Vigenere cipher uses a substitution technique in encrypting the message where each plaintext character in the message will be encrypted into another character in the ciphertext based on the key used. One Pad algorithm is one algorithm that has perfection when encrypting and decrypting it. The basic concept of the One Time Pad algorithm is almost the same as the Vigenere algorithm, except that in this algorithm the key is generated randomly. In this paper, we will explain how to strengthen Vigenere cipher by modifying Vigenere ciphers. Modifications are carried out by applying One Time Pad encryption generated from the key and the next key generation technique using Vigenere encryption continues so that the key used for the coding will be different from the key used previously. With the use of this method, the connection between plaintext and ciphertext will become less and more difficult to solve cryptanalis.Keywords: Cryptography, Modification, Vigenere Cipher, One Time Pad, and Cyber Security.

Abstract

Several new Islamic banking products have been created as a result of the increasing popularity of Islamic banking in Indonesia. Due to the technical advances made possible by the globalization era, all operations, including transactions, can be carried out easily and practically. One of the sharia banks that offers mobile banking services is Bank Syariah Indonesia. BSI Mobile still occupies the 49th position in the banking category according to statistics taken from Google Playstore, while other institutions are already in the top 20 positions. 5 linguists will annotate or manually label the app's 55,416 user-submitted reviews and ratings. 13568 review and rating data collected by app users after annotating or labeling and eliminating duplicate data will be used in this research. In the early stages of the sentiment analysis process, case folding, punctuation mark re-moval, stop word removal, and stemming were carried out on review and rating data. The Support Vector Machine (SVM) approach is used to evaluate training data and data testing using stemmed findings. In this study, the results of the training and precision tests were each worth 87.309%, and the results of the training and memory tests were both worth 86.958%. The training accuracy value is 85.87%, the projected sentiment analysis results have an accuracy rate of 85.87%, and the training results and precision testing are each worth 86.958%.

Abstract

Intercomparison of mass quantities is an activity to compare performance between laboratories ofmass quantities and reference laboratories which produces intercomparative data in the form ofconventional mass values and uncertainty values. Clustering of weights was carried out to obtain ananalysis of the laboratory’s participants management. The analysis carried out is very dependent on theaccuracy of the cluster. Clustering using self-organizing maps algorithm, and the results are tested for thelevel of homogeneity within the cluster and the level of heterogeneity between clusters using the icdrate value.The clustering of intercomparison’s data using the self-organizing maps method resulted in an icdratevalue of 0,0713 for an artifact of 1000 g and an icdrate of 0,2889 for an artifact of 200g
