In management education and psychology there are certain concepts that cannot bewell defined and then various discussions arise about the true meaning of the concept.Concepts such as management intelligence, personality, attitudes, interests, ambitions, socialprejudice and social status are hypothetical constructs that are not available in operationalmethods that can directly measure them. Concepts such as intelligence, personality, attitudes,interests, ambitions, social prejudice, social status are hypothetical constructs that are notavailable operational methods that can directly measure them. This study aims to determine thebackground of the use of Structural Equation Modeling (SEM), understanding SEM, basicconcepts of SEM: constructs, manifest variables, validity, reliability, factor analysis, polycoriccorrelation, causal relationships, LISREL: Linear Structural Relationship, SEM procedures :definition of variance and covariance, model specifications, model identification, modelestimation, model formation, model compatibility test, model specification, LISREL programoutput.

The development of company's business area will have implications for the development of computer network infrastructure as a means of exchanging data and information between regions. As a company that continues to develop its business area, PT. Timur Raya Lestari requires a computer network infrastructure that is adaptive to the development of the number of branch offices. The company's computer network currently uses the Static Routing method in determining the interconnection path between Routers connecting the head office and branch offices. The development of a dynamic company must be accompanied by the development of a dynamic network infrastructure as well. Development of a network infrastructure that continues to develop requires Dynamic Routing Protocol. In this study, it was simulated the use of EIGRP as Dynamic Routing Protocol for PT. Timur Raya Lestari. From the simulation results using Cisco Packet Tracer software, it can be seen that there is a stable interconnection, both for existing networks plan and planning for adding networks on new branch offices.

The need to access data remotely is a person's need to be more efficient in doing a job. Currently there are many remote access application programs, one of which is TeamViewer by utilizing the internet public network. By installing a TeamViewer program on a client and server computer someone can do data work and repair remotely as long as it is connected to the internet. To be able to do remote access, of course, a client must already know the user and password from the server computer. The disadvantage of TeamViewer is that other people will easily remote access data simply by entering the user and password that the computer has on the server. To overcome this problem, VPN technology is used with the PPTP protocol where only the IP address of the client that has been registered on the proxy device can access data on the server. VPN allows clients to connect to the server privately through public networks. To find out the performance of the VPN network that is built, QoS (Quality of Service) parameter analysis is needed which includes delay, jitter, throughput and packet loss. From the results of the tests carried out, the results of QOS with an index of 3.75, which if converted to the standard TIPHON, VPN network at STMIK STIKOM Indonesia has a satisfactory quality.

Student graduation data is a data that is important to the College, especially for the Faculty as well as the courses in question. Acquisition of knowledge in a database (a number of large data) commonly referred to as data mining. This research aims to analyze the student’s graduation predictions that can be done on a fourth semester using Multilayer Perceptron (MLP) classifier which available in WEKA software implementations. Then do the testing and performance comparisons of MLP against Naïve Bayes classification, IBk and Tree J48. Cross Validation and Percentage Split are used as the testing procedure in this research. The parameters in the process of testing using correctly classified instances and Root Mean Squared Error (RMSE). On the mode of Cross Validation, MLP has better performance compared to all contender methods with accuracy of J48 81.82% and the value of the smallest RSME i.e. 0.273. On a Percentage Split MLP mode has the same accuracy value with Naïve Bayes i.e. 92.31%, and the value of the RMSE on the MLP of 0.182.

Interkoneksi antar lokasi jaringan komputer (site-to-site network) sangat diperlukan dalam kaitannya dengan pengembangan organisasi. Pengembangan organisasi baik perusahaan swasta maupun instansi pemerintah umumnya berimplikasi kepada penambahan atau perluasan wilayah kerja. Dengan wilayah kerja yang semakin luas, tentunya akan membutuhkan fleksibilitas dalam proses komunikasi data antar wilayah. Untuk menunjang fleksibilitas komunikasi data antar wilayah, jaringan komputer harus dibangun menyesuaikan dengan kebutuhan organisasi tersebut. PT. Sab’a System Solution merupakan sebuah perusahaan swasta yang memperluas wilayah kerja hingga ke Semarang. Jarak yang jauh antara kantor pusat di Jakarta dengan kantor cabang di Semarang, membutuhkan infrastruktur jaringan komputer yang tepat agar kedua site dapat saling terhubung dan dipergunakan dalam komunikasi data. Solusi yang paling efektif dan efisien untuk menghubungkan kedua site tersebut adalah dengan menerapkan site-to-site Virtual Private Network (VPN) dan remote-access VPN untuk menunjang kebutuhan komunikasi bagi mobile user. Dalam penelitian ini, analisa, perencanaan dan desain VPN dilakukan menggunakan software simulator, sekaligus juga untuk menguji efektifitasnya jika nantinya diterapkan pada interkoneksi site-to-site. VPN yang di desain dalam penelitian ini dipadukan dengan IP Security (IPSec) sebagai protokol penunjang keamanan VPN tunnel, ketika data ditransmisikan melalui jalur publik/internet. Dari hasil pengujian, menggunakan software simulator, komunikasi data antar site bisa berjalan dengan lancar serta data telah terenkripsi dengan aman ketika melintasi jalur publik/internet.

Learning process should be an interesting process, especially for kids in elementary school. There are many methods has delivered to make the kids going fun to learn any new thing. Information and Communication Technolgy (ICT) could been involved to the learning process. ICT-based learning tools that used to help teachers and parents are developed in this research.   Astronomy is one of the fields of science which is generally taught in schools as a part of natural science subject. In this study, authors developed an astronomy learning application’s named Belajar Astronomi that comes as a supplement study material for elementary students. This Astronomy Learning application is designed to be a tool for students to study astronomy independently. Belajar Astronomi’s application developed with the Visual Basic programming language in Microsoft Visual Studio 2010 using Waterfall methods, to make sure Its functionality and usefulness. The application is equipped with images, text, and videos that can help students to learn astronomy more easily, Its also equipped with quizzes as training materials that can help students in sharpening their knowledge in Astronomy subject.

DHCP Server as part of the network infrastructure in charge of distributing host configurations to all devices has the potential to be controlled. If the DHCP Server is successfully controlled, all network devices connected to the server can potentially be controlled. From the observations made at PT. Rekayasa Engineering found a vulnerability in the DHCP Server that has the potential to experience DHCP Rogue or DHCP Spoofing, where the client will fail to communicate with the authorized DHCP Server, as well as open the door for attackers to enter the network. For this reason, DHCP Snooping and DHCP Alert methods are implemented. DHCP Snooping will ensure that every data traffic has been filtered and directed to the registered interface. Meanwhile, the use of DHCP Alert is required in monitoring data traffic during the Discover, Offer, Request, and Acknowledge (DORA) process. In the tests performed, DHCP Snooping and DHCP Alert managed to anticipate attacks that tried to placed DHCP Rogue on the network infrastructure. DHCP Alert, configured on the proxy router, ensures that the DORA process can only occur between an authorized DHCP server and a client. DHCP Snooping test also shows that communication from clients can only be replied to by Trusted DHCP Server. The existence of DHCP Snooping and DHCP Alert makes the host configuration fully controlled by the authorized DHCP Server.
