Dunia teknologi saat ini sudah sangat berkembang pesat seiring dengan perkembangan zaman yang sudah mengarah kepada pemanfaatan fungsi perangkat keras secara penuh seperti halnya adalah mesin pencetak dokumen atau sering disebut juga dengan printer. Penggunaan printer sangat dibutuhkan terlebih dikalangan akademisi, perusahaan kecil, menengah, dan atas sudah sangat ketergantungan kepada printer. Untuk menghindari kebutuhan printer yang begitu banyak maka ada solusi dengan cara melakukan sharing printer dimana tidak butuh banyak printer untuk melakukan pencetakan, cukup di share saja printernya kemudian gunakan kabel jaringan dan switch serta router untuk menshare printer dalam skala yang cukup besar. Namun apabila jumlah komputer terus bertambah atau bahkan ada pengguna printer namun dokumennya ada di laptop sedangkan kabel jaringannya sudah tidak cukup maka dibutuhkanlah sebuah teknologi jaringan yang disebut wifi. Tidak banyak printer yang dilengkapi dengan teknologi ini namun dapat dilakukan dengan cara menshare printer pada laptop kemudian menggunakan technology ad hoc pada laptop untuk mensharenya melalui wifi sehingga pengguna laptop lain dapat menggunakan printer tanpa harus terhubung dengan kabel jaringan. Untuk dapat melakukan share printer dengan wifi perlu dipastikan laptop ad hoc terhubung dengan kabel jaringan sehingga dapat melakukan share printer dan menggunakan static routing protocol dari Microsoft windows agar printer dapat di share dengan beda network.Keyword : Ad Hoc, Wifi, Printer, Laptop, Static Routing

This study uses the technique of incognito data and information into a container in the form of images combined with the addition of the password by using the method of Least Significant Bit (LSB) and the method of Haar Wavelet. Testing the system by sending a message in the form of a text file and an image file with the process of the original image are transformed to wear haar wavelet divided into four zones of frequency, namely LL, LH, HL and HH. Where Bit-bit Readings are planted in a zone LL and attempted insertion of the bit of the file reading into the last bit in each byte of the image file as well as can show you back the results of the message. The results of the research, i.e. images that have been processed by the method of LSB and Haar Wavelet does not change the file size, resolution, dpi and physical form image. The advantage of this method is very simple computing, oriented computers, which need less space to store and time efficient.

Light is energy lighting that can be used to transmit data and can reduce the use of the access point for local access in a building. The purpose of this paper is to implement technology Light Fidelity (Li-Fi) on the school library. Li-Fi has a very high potential in generating the connection data delivery fast. Li-Fi is even referred to as a technology that is better or superior than Wi-Fi (Wireless Fidelity). This is due to the broad scope of the installation is wider than Wi-Fi as well as the speed of sending data that far exceeds the Wi-Fi.  Wi-Fi uses radio waves as a mediator while Li-Fi uses light as a mediator to transmit data. For installation its own Li-Fi using tools such as server, lamp driver, Li-Fi dongle, as well as the device to be connected, such as computers, smartphones, and tablets.

The development of information technology is increasing rapidly over time, making data continue to grow and develop. Data has value, meaning and benefits, if it is processed into information or for analysis needs. Along with business growth, the utilization of existing information technology is considered still lacking, because the technology only supports operational database activities. Data warehouse is present to answer the growth of businesses that require very large data, through a data warehouse the company can findout the specific needs of its customers, and the results of sales. The aim of this research is to formulate a data warehouse model that is in accordance with the results of the company's needs analysis. The methodology used in this study uses the method of analysis and design. Where in the analysis method literature studies, surveys and interviews are conducted, identifying information needed by managerial in decision making. While the data warehouse design method uses a star scheme because it is easily understood and used in the process of forming queries. The results of this study are in the form of a data warehouse model that is formed from operational data, processed in various dimensions that exist, sothat it can form a report to meet the managerial needs of information. With the existence of this data warehouse, managerial parties can analyze the reports generated from various perspectives easily
