Appropriated artwork refers to the practice of using pre-existing objects or images into new works of art with little or no significant changes to the original form. This trend developed into the Pop Art movement, where one of the characteristic features was the use of images from mass media, as seen in the works of Andy Warhol, including the transformation of Campbell's soup cans into iconic works of art. Although widely appreciated, this work has drawn criticism regarding copyright infringement, raising the question: where do one artist's rights draw on another? To what extent is the appropriation of copyright protected works considered legal without violating the rights of the original creator?
The research results show that the two legal systems differ significantly in the aspects of exclusive rights, moral rights, protected works, exceptions, and duration of protection. The challenge in understanding fair use lies in determining the boundaries between the rights of one artist and another. The fair use doctrine assesses four main factors: the purpose and character of the use, the nature of the original work, the proportion of the work used, and the impact on the market. Courts in the US often favor fair use if elements of transformation are identified, measuring the extent to which the appropriated work carries elements of originality or new creativity. Indonesia could consider adopting the fair use doctrine by adapting the concept through ministerial regulations or other implementing regulations.

The purpose of this study is to examine the legal standing of testaments that forgo a spouse's right to inherit in the event of their death. This study is necessary because, while everyone has the right to draft a testament according to their desires, this does not absolve the contents of the testament from being based on applicable laws and regulations. This study was carried out utilizing a doctrinal and statutory method in a normative juridical manner. The study concludes that a testator's intentions are free to be included in a will; nonetheless, the Indonesian Civil Code governs the legitimacy of Legitieme Portie. Thus, if a testament is written by a spouse whose marriage has entered into a marital agreement to separate assets, and its contents eliminate the longest-living spouse's inheritance rights, then that will not violate the rights of the longest-living spouse because it is based on Article 914 of the Indonesian Civil Code that the husband or wife does not have Legitime Portie. In the meantime, a testament written by a spouse whose marriage did not result in a marital agreement that separates assets only applies to the portion of the maker's assets; in other words, the longest-living spouse still receives a share as part of the joint assets in marriage. 

Every person experiences disagreements, conflicts, issues, and confrontations in their lifetime. Nobody wants to get into a disagreement with someone else. Each business actor, particularly in economic activities, should always be prepared for the possibility of disagreements that may arise at any point in the future. Here, the business actor will select the form of dispute resolution that best fits their requirements. This study employed a normative juridical research methodology that combines a doctrinal and statutory regulation approach. This study concludes that arbitration is a non-litigation dispute settlement mechanism. With its many benefits, arbitration plays a big part in settling business conflicts.
