Content Based Image Retrieval (CBIR) is a research cluster that is very important to overcome problems related to the image search process. The development of internet technology and data communication has caused the number of multimedia images currently circulating to be very high. This study took the Color Moment method to carry out the feature extraction process. Before the feature extraction process, a segmentation process was carried out to separate the background image and the foreground image. Next, each background and front image is stored in the database. Method performance measurement is done by calculating the value of precision and recall. The test image used is the Wang dataset consisting of ten image classes. The test results show the level of recall or completeness of the images that were found to have increased significantly after using the K-Means segmentation process. But a high enough recall value decreases the value of precision or the comparison of true images with the image found overall. Precision values ​​decrease when compared to the CBIR method without running the K-Means segmentation.

The judge's interpretation of the novelty principle, where the Panel of Judges in industrial design disputes argues that an industrial design can be said to be new if it has undergone a significant change in visual appearance, meaning that the visual appearance of the two objects is very different. If not, then the modification of a product cannot be called new so that it cannot be considered as an industrial design. The problems of this research include: how is the regulation of product novelty in the registration of industrial designs in Law Number 31 of 2000 and how is the legal protection of designers against the concept of novelty of products in the legal system in Indonesia. This type of research used in discussing the problem of this research is normative legal research. The conclusions of this research are as follows: Regulations on Product Newness in the Registration of Industrial Designs in Law Number 31 of 2000, among others, are in Article 9. And legal remedies are contained in Article 54 of Law Number 31 of 2000. Legal protection of designers against the concept of product novelty In the legal system in Indonesia, among others: Preventive protection: This protection is also closely related to the awareness of the owner of the industrial design rights themselves to register their industrial designs in order to get protection from the State. Regressive protection for holders of Industrial Design Rights is protection that is carried out directly to resolve or overcome an event or incident that has occurred in the form of a violation of the right to industrial design.   Penafsiran terhadap penerapan prinsip kebaruan (novelty) oleh hakim, dimana Majelis Hakim dalam sengketa desain industri berpendapat bahwa sebuah desain industri dapat dikatakan baru apabila telah mengalami perubahan penampakan visual yang signifikan, artinya penampakan visual kedua benda tersebut menjadi sangat berbeda.
