Abstract

Data-based planning training is carried out online based on various sources which can be used to carry out or prepare an agenda for future activities and budgets. The data-based planning training activity was carried out online for two days. This implementation started with the experience of the school principal sharing his experience with the education unit in planning and compiling activities and making budgets at the school, then the facilitator provided reinforcement for data mining from the independent teaching platform (PMM ), Education Report Card Platform as well as through data sourced from the North Sumatra Education Quality Assurance Center (LPMP). Then the facilitator reflects on the training on the material that has been explained. On the second day of implementation, each educational unit grouped to discuss and fill in the evaluation sheet, then carried out identification, reflection and improvement in planning activity plans and preparing budgets for the unit, then apart from that, the educational units held discussions to make follow-up plans starting from the date, unit involved and the media used. Next, reflect on your experience at school, then work on an evaluation worksheet that is synchronized with the Identification worksheet, then a reflection worksheet and a fix worksheet, then the education unit finishes working on an activity plan that comes from several data and can prepare a budget that is planned for the long term.

Abstract

The development of the world of information technology is very fast lately influential in all aspects of life. Kriprografi is a science based on mathematical techniques to deal with information security such as confidentiality, data integrity, and entity authentication. Affine Cipher or Affine password is a substitution cipher that is specifically for encryption or decryption per character. Therefore, Affine's password includes the stream cipher cryptographic algorithm. Steganography is a way of hiding the contents of a data in a cover of media or other digital data that cannot be predicted by ordinary people so as not to arouse suspicion from those who see it. The steganography image file has the same number of pixels as the original image file and there is no color difference between the two. The size of the steganography image file will increase, according to the length of the hidden message plus 6 bytes, in the form of 1 byte EOF and 5 byte message length. The End Of File (EOF) method is a technique for inserting data at the end of a file. When opened with a photo editor application, both images have the same pixel size, namely 240 x 238, and do not change color. In this test, what changes is the size of the image file, ie the initial size of the image is 49.132 bytes, changes to 49.145 bytes, or there is an addition of 13 bytes
