Document interception is the most feared thing by communication network users at this time. Currently, documents are very easy to be stolen, because the level of security of the document itself is often forgotten so that advanced security is needed in securing the document. One of the documents that will be secured is a PDF (Portable Document Format) file because the advantage is that it can be opened on any computer or even a smartphone without any changes to the data or contents. However, since the conversion from PDF to Word, many files have been manipulated so that PDF is very important to be safe. The increase in data theft, data piracy, and misuse of the data resulted in losses for the owner of the data, information, and documents. Cryptography is a good solution in securing data, cryptography has two techniques, namely encryption, and decryption where encryption is to change the data to be not understood while decryption returns the original data. There are many cryptographic algorithms such as Rijndael, Serpent, Twofish, MARS, RC6, MRC6, RSA, and others, Rijndael algorithm supports key lengths of 128 bits, 192 bits, and 256 bits. Lock length and block size can be selected independently. The encryption and decryption tests were carried out using the Android platform with the implementation carried out on an image measuring 300 x 300 pixels. Rijndael algorithm has image encryption speed is 174% faster. So, it can be concluded that the Rijndael Algorithm has advantages in doing encryption and decryption very quickly and better.

Salim Ivomas Pratama Tbk is a company engaged in processing palm oil into cooking oil packaging. In determining the amount of packaged cooking oil production, it is still manual so that the results are still not optimal, therefore to determine the amount of packaged cooking oil production to meet market demand that fluctuates and does not remain constant from time to time, an alternative is needed that can overcome the problem. One solution to overcome the problem of the amount of production is to use a decision support system with a fuzzy Tsukamoto approach. The author designed a Decision Support System in Determining Cooking Oil Production at PT. Salim Ivomas PratamaTbk Using the Fuzzy Tsukamoto Method. The program used is Visual Basic 2010 and uses Microsoft SQL Server 2008 as the database. With this system, it is expected that PT.

At present, in the world of work there are three generations that color the workforce, namely baby boomers born in 1943-1960, generation X 1961-1979 and generation Y 1980-1994. Generation Y is an individual born in the development of information technology and a high level of education so that Generation Y is very achievement-oriented, hard-working and will strive to achieve success but Generation Y has a tendency to move around at work, lack of work commitment so that this causes companies to experience difficulties in determining the performance commitment of generation Y if this continues it will have an impact on the sustainability of a company, so we need a certainty factor method to determine the work commitment of generation Y. from research that has been done by taking one sample by applying the certainty factor method produced that one of the Y generation has a commitment to the feeling of love in an organization that raises the willingness to stay and foster social relationships and appreciate the value of relationships with the organization because it has become a member or ganisasi (Affective commitment)

Keamanan data merupakan hal yang sangat penting dalam menjaga kerahasiaan informasi terutama yang berisi informasi sensitif yang hanya boleh diketahui isinya oleh pihak yang berhak saja.Salah satu cara untuk meningkatkan keamanan data adalah denganMenggunakan teknik kriptogtafi yang mencakup proses enkripsi dan deskripsi Kriptografi mempunyai tiga unsur penting Yaitu pembangkit kunci, enkripsi dan deskripsi. Dalam kriptografi di kenal algoritma block chiper yang didalamnya terdapat AES-128 merupakan bagian dari Modern Symmetric Key Cipher, algoritma ini menggunakan kunci yang sama pada saat proses enkripsi dan deskripsi sehingga data yang kita miliki akan sulit dimengerti maknanya. Teknik algoritma tersebut digunakan untuk mengkonversi data dalam bentuk kode-kode tertentu, tujuan agar data yang tersimpan tidak bisa di baca oleh siapa pun kecuali orang-orang yang berhak. Saat ini tidak adanya penerapan keamanan data pada sistem absensi karyawan di Balai Penelitian Sei Putih menyebabkan mudahnya data dimanipulasi oleh orang yang tidak berhak. Sehingga dengan penerapan algoritma AES-128 diharapkan dapat meningkatkan keamanan data absensi dan mampu melindungi data dan sistemnya dengan mengenkripsi dan mendeskripsi data absensi sehingga bisa di peroleh keaslian data sebenarnya

Queuing simulation is very much needed by Sat. Then the Deli Serdang Police because the number of queues every day is very long making it difficult for Sat Then to serve applicants for a driving license (SIM). Judging from the length of the queue every day, Sat Then the Deli Serdang Police need a system that can make it easier for Sat Lantas to determine the most efficient time in queuing. Because currently the system being used is still very manual, thus making the prospective driver's license (SIM) applicant become bored waiting to be served even though the facilities provided by the Sat Lantas are quite adequate. So to overcome the long queues every day, a queue simulation is needed to solve the problem of the fastest time in queuing using the exponential method.
