Memainkan game merupakan salah satu cara membuang stress pikiran pada saat tertentu ketika seseorang membutuhkan. Smartphone merupakan perangkat modern yang memiliki banyak developer aplikasi, salah satunya adalah developer game. Sebelum munculnya smartphone, terlebih dahulu muncul game-centre yang banyak diminati oleh masyarakat, mulai dari muda hingga tua, dan bahkan kaum hawa pun ikut tertarik. Pacman merupakan salah satu nama game terkenal pada tahun 1980-an, yang saat ini juga dikembangkan ke platform android. Dalam penelitian ini dilakukan implementasi algoritma A* kepada NPC Ghost yang akan mengejar dan memburu pacman dalam labirin hingga nyawa pacman habis dan game over. Dilakukannya implementasi algoritma A* adalah agar ghost dapat menemukan jalur tercepat ke pacman agar permainan terasa lebih intense.

The future of a nation depends on how good the quality of education and human resources of the nation is. Higher education is an important part of the world of education that carries the responsibility in an effort to educate the nation's life. This study aims to determine the factors that influence student attitudes in choosing to continue their studies at Islamic Higher Education (PTAI). The background of this research is that there is a significant gap between PTN and PTAI enthusiasts and the lack of student interest in Islamic tertiary institutions is very interesting to be used as research study material to find out things that are considered by students in choosing PTAI. The results of the study indicate that the data used have met the assumption test of validity, reliability, adequacy and feasibility of the data so that it can be continued in the next analysis using factor analysis using PCA. All the variables contained in this study have an extraction value of more than 50%, so it can be concluded that all the variables used can explain these factors. In the "% of variance" column, because the specified eigenvalues ​​is 1, then the value to be taken has eigenvalues ​​greater than 1, there are component 1, component 2, component 3, component 4, and component 5. If you use 5 components then the total factors that can explain the variance are 20.011% + 19.692% + 15.935% + 14.632% + 10.745% = 81.015%

The need of servers is currently growing rapidly. Every company or school needs a server to store electronic data properly. As for email and Information Systems with cloud servers, it is expected to be accessible to users from anywhere. But in building a server there are several security problems that often occured, such as the server being hacked, and causing the data to be lost. From these problems, a study was made to produce a discussion of security management in a cloud server with a minimum cost that can be applied to a company or campus or another. In scanning security on the cloud server, Android authentication can be used. Each root user will log in to the cloud server, then Android authentication will send a data. Apart from android authentication, security can use firewall ip tables in the cloud server and added with SSL (Secure Socket Layer), in every data from, and, to the encrypted server.Abstrak-Kebutuhan akan server saat ini berkembang pesat. Setiap perusahaan atau sekolah membutuhkan server untuk menyimpan data elektronik dengan baik. Seperti untuk email dan Sistem Informasi, dengan cloud server diharapkan dapat diakses pengguna dari manapun berada. Tetapi dalam membangun sebuah server ada beberapa masalah keamanan yang sering terjadi, seperti server dibobol, dan menyebabkan data server hilang. Dari permasalahan tersebut, dibuat suatu penelitian untuk menghasilkan pembahasan manajemen keamanan dalam cloud server dengan biaya minimum yang nanti dapat diterapkan pada suatu perusahaan atau kampus maupun yang lain. Dalam mengeloa keamanan pada cloud server dapat digunakan authentication android. Setiap user root yang akan login pada cloud server, kemudian authentication android akan mengirimkan sebuah data. Selain dari authentication android, pengamanan dapat menggunakan firewall ip tables di cloud server dan ditambahkan dengan SSL (Secure Socket Layer), di setiap data dari, dan, ke server yang dienskripsi.

During the pandemic, many events are held online. conference registration (webinars, seminars, workshops) which basically will cause its complexity for admins if there are excess registrants or over participants from achieving the registration quota target. In addition, the admin must monitor regularly to ensure that there are no excess registrants that result in inefficient. The method used in the development of this application is the waterfall method. The purpose of this research is to build a web-based conference registration system that can make it easier for admins/organizers to manage the registration process. The results of this study the system can display the results of the recap from the admin so that the user can see the quota from the conference registration organized by the committee as well as testing of users from several tests to produce an application system that runs well.
