Submission of information is an important thing in a system. A good system that is able to communicate to its users by conveying information correctly and clearly. In the examiner rating system found in Raharja College before the system still did not provide information about theprofile of the Thesis and Final Project students. Submitting the lack of information is felt to make the previously running system unable to communicate to its users. Therefore it is necessary to develop a student profile information system so that it can communicate to its usersclearly. After the examiner assessment system that has been developed becomes online, the student profile information system is also developed online by adding some information that can make the system more communicating to its users. Research to develop a student profile information system on the assessment of trial examiners using observational research methods, interviews and literature studies. The researcher made observations by looking at the shortcomings of the system, then conducting interviews with stakeholders, then the researchers sought similar research in order to solve the problems that had been obtained. It is expected that after being applied to the Testing Assessment system, the delivery of information regarding the profile of the Thesis trial and Final Project students can be better and clearer.

The development of information technology is growing rapidly as one of them used to interacting with other people. Information technology can connect us with others regardless of time and place. This is possible because of the existence of a container that community (forums) discussions on-line learning. However, in Higher Education of Raharja the development of discussion for learning is less developed for regular class or a class that is not a superclass or i-learning class because the manual is face to face or face to face for the discussion of learning in Higher Education of Raharja. Therefore, it can be made a formal community for container or the learning process in order to facilitate the discussion of faculty and students in the learning process outside of lecture hours that can be accessed anytime and anywhere and can provide accurate information so that the information obtained by the faculty and students to be more relevant. Discussion of web-based learning system is designed with a user friendly system so that  is easy to access and understand, facilitate communication between faculty and students, and also facilitates getting materials lecture material, as well as assist in the distribution and collection of duties and tasks quickly lecturers also can manage the values that will given to students. The methodology used is a structured analysis and development ranging from analyzing the system that runs through UML, perform elicitation, and describes the proposed system through UML. The final results are achieved from this research is the creation of a learning system that can be accessed anywhere, anytime, and always follow the lecture material information or update

Sharing data adalah proses dimana suatu data pada suatu komputer dapat digunakan oleh komputer lain dengan syarat kedua computer tersebut sudah tersambung dalam sebuah jaringan komunikasi. Agar komunikasi data bisa berjalan, dibutuhkan sebuah tools yang bernama Wireless. Oleh karenanya penelitian ini dilakukan dengan metode studi pustaka dan observasi komponen yang dibutuhkan, analisis fungsi setiap aplikasi baik yang dibutuhkan pada system computer maupun media smartphone, merancang konfigurasi system wireless dan implementasi konfigurasi system wireless serta melakukan uji-coba secara “trial and error”.   Dengan system wireless ini,  jaringan tanpa kabel yang menggunakan udara sebagai media transmisinya dapat menghantarkan gelombang elektromagnetik. Selain wireless dibutuhkan juga aplikasi pendukungnya lain seperti system operasi android yaitu Airdroid. Airdroid merupakan sebuah aplikasi Android yang memungkinkan untuk mengirim data perangkat Android tanpa kabel dengan menggunakan Perangkat komputer (PC).

Financial ratios are very important in a company, because it is the most effective way to find out financial data on a company by comparing the current financial statements of the company with the previous one.

Closing the book itself is useful to determine the company's financial position before closing, by looking at the final results of the profit and loss. It is known that the process of closing the book takes a long time with extra precision. However, this has become easier by using WBAOS (Web Based Accounting Online System) 2.0, because companies are more flexible in preparing financial statements, starting from the lane balance sheet, income statement, to the periodic cash flow, where this cash flow provides relevant information regarding cash in and out of the company.   Keywords: ​WBAOS, Financial Ratios and Book Closure.
