Learning media is a medium used in teaching and learning activities. As is known, the world is currently experiencing a Covid-19 pandemic so teaching and learning activities are carried out online. One of the media that can be used as distance learning is a web blog. Web blogs are chosen because they do not require a lot of money to create and can be combined with other media such as YouTube. This study aims to produce a web blog as a distance learning media for graphic design study programs. Because the lecture material uses more application practice, the web blog and YouTube media are very appropriate to use. This is in accordance with the results of the questionnaire distributed to graphic design students in semester 3 and 5 of STEKOM University regarding the use of a web blog. From 38 respondents and after being calculated based on existing references, the final score was 88.42% so that this web blog was in the "very good" category and could be used as a reference.

SMK Negeri 11 Semarang is a school that has four competency skills, namely Graphic Preparation, Graphic Production, Multimedia, and Animation. Every time they enter the beginning of the school year, school socialization and skills competencies are carried out to new students through the Student Orientation Period, using the lecture method from each of the Head of Skills Competencies. Researchers have created an attractive and informative audio-visual presentation media, packed with docudrama stories, namely documentary films. The results of validation tests conducted by expert experts and users show that the documentary films that have been developed by researchers fall into the very good criteria with a percentage of 93.75%. In addition, through the use of the 228 new students as respondents, it can be concluded that the documentary film developed by the author falls into the good criteria with a percentage of 61%.

Photography copyright works in Istagram are regulated in Article 40 paragraph (1) letter k of Law number 28 of 2014 concerning Copyright. The background of this research is that the public does not understand the element of copyright protection in every photographic work uploaded on Instagram social media. When someone downloads a photographic work without the permission of the owner of the work, even though this has often been done, from a legal standpoint there will be legal consequences and even lead to sanctions. The problem is whether the state provides protection for photographic copyrighted works and what are the legal consequences if the download is done without permission. The method used in this research is normative juridical, namely research based on secondary data, which is then analyzed qualitatively and presented in a qualitative form.The results show that the state has protected photographic copyright works, through Article 1365 jo 1367 KIHPer, Article 25 of Law No. 19 of 2016 concerning Electronic Information and Transactions, Article 40 paragraph (1) letter k and Article 59 of Law No. 28 of 2014 concerning Copyright and Joint Regulations of the Minister of Law and Human Rights and the Minister of Communication and Information Technology No. 14 of 2015 and No. 26 of 2015. The legal consequence is that if a person makes a download without permission, under Article 113 of the Copyright Law, he can be sentenced to a maximum of 4 years in prison and / or a maximum fine of 1 Billion, based on Article 48 of the ITE Law, imprisonment of 8 - 9 years and / or 2 M.           Keywords: Legal Protection, Copyright, Photography, Social Media

The purpose of this study is to determine the protection of consumers who use cosmetics that are not registered with the BPOM, the legal consequences for cosmetic business actors who do not register their product distribution permits with BPOM and the solution. The research method used was normative juridical, with a descriptive analytical research specification. Obtaining data using secondary data through library research and interview techniques as a complement to secondary data which is then analyzed using descriptive qualitative methods. From the research results, it is concluded that the legal consequences for cosmetic business actors who do not register their product distribution permits with BPOM are administrative sanctions and criminal sanctions in accordance with Articles 45, articles 60 and 62 of the Consumer Protection Law Number 8 of 1999, Article 47 Paragraph (2) Regulation of the Food and Drug Supervisory Agency Number 12 of 2020, Article 20 of Minister of Health Regulation Number 1175 / Menkes / Per / XII / 2010 concerning Cosmetic Notifications, Articles 98, 106, 196 and 197, UUN Number 36 of 2009 concerning Health. The solution to this problem is that before distributing the cosmetic products it produces, business actors are required to register their products with BPOM in advance, so that there are no complaints, lawsuits and even criminal sanctions.           Keywords: Consumer Protection, Cosmetics, Distribution license, BPOM

The transformation of objects in computer graphics is very closely related to the factor of scale and rotation. Both are often a challenge in the introduction of objects through numerical features in digital images. Feature processing techniques that can overcome these problems such as Distance - Angle signature that is invariant to the scale and rotation factor. From the results of experiments conducted on 5 types of geometric shape images which amounted to 15 data with scale and rotation factors obtained the results that the Angle Signature can be applied well on all data. Inequality in the signature plot images obtained is due to the lighting conditions and background objects that are not uniform, which occurs in the image of a circle for all three types.

In the daily use of technology, humans cannot be separated from the internet as a need to exchange information. People at this time spend more time in front of computer screens, laptops, even smartphones to find out information, send data to some of their friends. One of the information that is often sought or sent is a file. Apart from that, image files are files that are much searched for and sent, and many also contain important information in them. Image file security is of course very important so that unauthorized parties do not hack or manipulate information from the image. There is a way to secure information so that it does not leak to unauthorized parties, namely by using cryptography and steganography. By combining these two methods, you can maintain the confidentiality and security of a file, especially image files. In this study the algorithm and method used is the AES cryptographic algorithm (Advanced Encryption Standard) 256 and the LSB (Least Significant Bit) steganography method. Data integrity needs to be tested to ensure that the encryption and decryption processes are running properly. Data integrity testing uses the SHA-1 method. Likewise, the image quality after insertion will experience a decrease in quality. To evaluate this, it is necessary to test using the PSNR method. From the results of data integrity testing by comparing the hash value of the decrypted image file with the original image file, there is no difference. So this shows that the encryption and decryption process was successful. While in testing using the PSNR method, the average PSNR value is 44.14086 dB and with an average error value of 2.830403 dB, which means there is a small decrease in quality. From the implementation and testing results, it can be concluded that the AES 256 cryptographic algorithm and the steganography method LSB can be implemented in maintaining the confidentiality and security of secret messages.
