Abstract

Cryptography is used to protect the contents of information from anyone except those who have the authority or secret key to open information that has been encoded. Along with the development of technology and computers, the increase in computer crime has also increased, especially in image manipulation. There are many ways that people use to manipulate images that have a detrimental effect on others. The originality of a digital image is the authenticity of the image in terms of colors, shapes, objects and information without the slightest change from the other party. Nowadays many digital images circulating on the internet have been manipulated and even images have been used for material fraud in the competition, so we need a method that can detect the image is genuine or fake. In this study, the authors used the MD4 and SHA-384 methods to detect the originality of digital images, by using this method an image of doubtful authenticity can be found out that the image is authentic or fake.Keywords: Originality, Image, MD4 and SHA-384

Abstract

E-Raport application is an effort to control the quality of assessment, given the limitations of existing resources and qualifications. Value data in E-Raport is a matter of confidentiality that is very guarded to avoid irresponsible parties. One solution to the problem above is to encode the e-raport database record so that the value data can be maintained and confidentiality protected. One of the algorithms that can be applied is the Double Data Encryption standard (2DES). By applying the 2DES algorithm the value data in the E-Raport application is protected from other irresponsible parties and the assessment system can run well and the value data can only be accessed by users who are has access rights to process the data value.Keywords: Value Data, E-Raport, Cryptography, 2DES algorithm

Abstract

Steganography is the science and art of hiding (embedded) information by inserting secret messages in other messages. Steganography in the field of information technology is highly developed, namely for digital devices. Information or messages that can be hidden varies, as can messages that are embedded objects. Variations of messages that are normally subject to insertion objects are text messages, picture messages, audio messages, and video messages. The steganography method used is the Modulus Function (MF) method. This method can insert more messages into pixels that have high contrast values. The research conducted is applying the Modulus Function (MF) method for inserting messages into image files. Based on the test results, it can be concluded that by using the Modulus Function (MF) method, the capacity of the image to insert a message is smaller than the image size, the processing time in this method is quite fast, the image quality after inserting a message has good quality, but this method is also still good. has disadvantages, because it is not resistant to manipulation and in some images are still detected by the matlab application.Keywords: Steganography, Implementation, Modulus Function (MF), Image file.

Abstract

Tinter is the person in charge of installing window film on building windows or car windows. A tinter must have some specific criteria set by the company. To increase motivation and quality of a tinter's work, the company routinely holds the selection of the best tinter each year. However, the selection of the best tinter made at this time is still not completely in accordance with the specified criteria and in the end the selection is based on the assessment of the company's leadership. It is feared that it will cause divisions between tinter who feel that the selection is unfair or not objective and does not conform to procedures. For this reason, a decision support system is needed for the selection of the best tinter. Decision support system used is to use the Additive Ratio Assessment (ARAS) method because this method is a multi criteria decision making method based on the ranking concept.Keywords : Tinter, System, Decision, SPK, Additive Ratio Assessment, ARAS

Abstract

Desain pengontrolan daya resistif menggunakan mikrokontroler dengan TRIAC adalah topik utama penelitian ini. Sakelar TRIAC dihubungkan antara sumber AC dan beban, sehingga aliran daya dapat dikontrol dengan memvariasikan tegangan efektif yang diberikan ke beban. Pengontrol kecepatan motor induksi tiga fase, kontrol pencahayaan, dan pemanas industri sering menggunakan teknik ini, yang disebut sebagai regulasi tegangan AC. Untuk memahami prinsip kerja sistem ini, diperlukan eksperimen dengan modul kontrol Daya. Penggunaan TRIAC berbasis mikrokontroler sebagai objek penelitian untuk desain pengontrolan daya resistif melibatkan simulasi rangkaian pemicu TRIAC dengan mikrokontroler AT89S51. Prinsip kontrol daya resistif dengan TRIAC adalah mengatur aliran daya ke beban dengan menunda sudut pemutusan thyristor. Mikrokontroler AT89S51 berperan sebagai pengontrol utama, mengambil keputusan berdasarkan informasi dari sensor zero-crossing detector. Pengujian dilakukan dengan menambahkan lampu sebagai beban. Temuan percobaan menunjukkan bahwa mengubah tegangan pemicu berdampak pada tegangan output, yang pada akhirnya mempengaruhi variasi kecerahan lampu dan peningkatan arus output. Berdasarkan analisis, sudut pemutusan menurun seiring dengan naiknya tegangan output thyristor. Hubungan antara perubahan tegangan output dan penyesuaian sudut pemutusan thyristor sangat penting untuk aplikasi kontrol daya. Untuk mencapai pengaturan daya resistif yang efisien dengan menggunakan TRIAC, pembahasan ini juga menekankan pentingnya komponen seperti mikrokontroler dan sensor zero-crossing detector.

Abstract

Each lecturer has a different way of teaching, some are preferred by students and some are not liked by students. A lecturer is required to improve his performance in teaching and imparting the knowledge he has to his students, so there are several requirements that are used as criteria in determining the best lecturers including Doc Scopus, Position, Competence, Age, and Warning Letters. So that in this study a money system was made using a decision support system that could determine the best lecturers during the covid-19 pandemic. In its determination, data such as criteria, weights and alternatives are needed. So, in this study using the OCRA (Optional Competitiveness Rating Analysis) method to determine the Best Lecturer through data such as alternatives and criteria, it can be concluded that the second alternative (A2) is Kennedi as the best Lecturer with the best preference value of 3,837.
