Abstract

Alasan penulis untuk melakukan penelitian ini dikarenakan Pada abad 21 ini teknologi informasi dan komunikasi berkembang dengan pesat, dan mempunyai banyak dampak dalam aspek kehidupan. Salah satunya berdampak bagi pelaku foreign exchange (forex).Para pelaku foreign (trader) sebenarnya dapat lebih mudah dalam memantau fluktuasi dengan memanfaatkan teknologi yang canggih pada saat ini, tanpa harus membuang waktu untuk selalu memantau melalui Website. Sayangnya, belum ada trader yang mempunyai ide untuk membuat aplikasi ini pada mobile phone android. Oleh karena itu penulis mempunyai ide untuk merancang aplikasi yang melakukan pemantauan dengan memanfaatkan aplikasi android dan autonomous agent berbasis JADE (JAVA Agent Development Environtment). Pada penelitian ini, penulis menawarkan kemudahan kepada trader. Karena nantinya Trader hanya akan menginputkan rule pemantauan yang berisi kode valuta, jenis transaksi, kondisi dan nilai yang diinginkan. Saat rule pemantauan terpenuhi maka trader akan mendapatkan notifikasi pada Smartphone Android yang digunakan, Pemanfaatan aplikasi tersebut dapat memberikan waktu luang para trader untuk mengerjakan pekerjaan yang seharusnya dikerjakan tanpa membuang waktu untuk melakukan pemantauan fluktuasi valuta asing secara langsung, tanpa takut kehilangan informasi.Keywords : Valuta asing, Android, Autonomus Agent, Framework JADE

Abstract

AbstrakGauss menguraikan tiga teori untuk menyelesaikan persamaan linier. Dimana teori tersebut diturunkan dari metode eleminasi penjumlahan, pengurangan dan subsitusi. Kendala yang ditemukan dikelas adalah mahasiswa lambat memahaminya, sehingga diperlukan modifikasi metode Gauss yang dapat menerangkan dan menjembatani peralihan dari metode eliminasi ke metode Gauss.Peralihan yang dapat dilakukan adalah dengan menggabungkan dua teori Gauss/Operasi Baris Elementer yaitu dengan menggabungkan mengalikan sebuah baris dengan bilangan k ≠ 0 dari matrik A yang disebut Operasi Tipe II dan dengan menambahkan sebuah baris i dengan mengalikan k ≠ 0 pada baris yang lain dimana i ≠ j dari matrik A disebut Operasi tipe III menjadi satu yaitu dengan menambahkan k1 ≠ 0 kali baris ke i dengan k2 ≠ 0 kali baris ke j dimana i ≠ j dari matrik A yang disebut sebagai Modifikasi Operasi Tipe III.Modification of Gauss Method or the Elementary Row Operations System Solutions of Linear Equations of 3 Variables and 3 EquationsAbstractGauss outlines three theories to solve linear equations. The theory derived from the Elimination Method such that addition, reduction and aubstitution. Problems were found in class is a slow student to understand it, so that the necessary modifications Gauss method that can explain and bridge the transition from Elimination Method to Gaussian Method.Transition to do is to combine the two rule of Gaussian Method / Elemantary Row Operations by the incorporation multiplying a row with number k ≠ 0 of matix A so-called Operation Type II and by adding a row i by multiplying k ≠ 0 on the other row where i ≠ j of matrix A is called Operation Type III into one by adding k1 ≠ 0 times row i with k2 ≠ 0 times row j where i ≠ j of matrix A is referred to as Modification Operation Type III.

Abstract

This paper is a study of students’ perception onto UNAI online system. The data for students’ perception is obtained from questioners filled through online by students. The objective of the study is to see how well UNAI online system perceived by students. The study was conducted during the odd semester 2021/2022. The population was 1636 students, and samples taken randomly was 105 students. The questioner consists of 6 parameters of perception: benefit of online system, usage simplicity, friend support, facility completeness, usage interest, dan usage frequency. The study shows that based on individual regression analysis, the benefit, simplicity, friend support, facility completeness significantly have a significant effect on interest to use the online system, and the interest to use the online system has an effect on usage frequency. However, on simultaneously regression analysis among the four parameters, only two parameters (the perception of benefits and facility completeness) have a significant effect on students’ interest using the online system. Based on cross tabulation analysis, faculty of education students have better perception on UNAI online system compared to other faculty students, senior students have better perception compared to other batches, and female students have better perception than male students. The findings of the study imply that the facility of online system, in terms of network, bandwidth, computer facility, and learning resources need to be accomplished in order to improve the students’ academic achievement during the online learning era due to covid-19 pandemic.

Abstract

Internet services and technology are rapidly expanding in terms of complexity, design, management, and operation leading to an increase in the number of connected devices, and the traffic on the network has increased very rapidly in recent years. Also, emerging new service developments and the use of high mobility and server virtualization, cloud computing, and the Internet of Things are being developed resulting in a network architecture that is currently very limited in capabilities. Software Defined Network technology is a new concept in designing, managing, and implementing network architecture by separating the control system from the forward system on network equipment. Software Defined Network allows the network to dynamically adjust the environment to simplify management and increase network scalability through the simple implementation of additional network components and services. Therefore, higher requirements are put forward to improve network performance and eventually network control becomes increasingly complex, inconsistent, and inflexible. Network performance can be affected by many factors, such as network configuration, number of requests, and network management methods

Abstract

The model built using the data mining process can be used to make predictions from the data. The model can be built using a datasheet that contains data that is processed from the process. One implementation of the model in data mining is the prediction of a disease such as diabetes. In this study, a data mining model was developed using the k-NN algorithm and data normalization was carried out. The normalization method used is Z-Score and Min-Max. The research methodology is carried out by first determining the datasheet, selecting the data mining model and dividing the datasheet into datasheets into training data and data testing and evaluating the performance of the model created. The process of modeling using python programming. The data mining process uses a classification model using the k-NN algorithm. The datasheet used is a public datasheet, namely the diabetes datasheet which consists of 768 records and 8 attributes. The results of this modeling show that the normalization process can provide better accuracy values. The model developed without normalization produces a value of k=5 with an accuracy of 70%, normalization with the Z-Score method produces a value of k=21 with an accuracy of 72%, normalization with Min Max produces a value of k=3 with an accuracy of 74%. The recommended model is k-NN mode with a value of k=3.
