Abstract

Even though phytoremediation is considered a green technology for remediating heavy metals, there are some problems with the application of this technology, particularly when it comes to managing the biomass that is used. So, processing biomass needs to be given a lot of attention. This study outlined the utilization of extracts obtained from the hyperaccumulator plant Brassica oleracea var. alboglabra to synthesize nickel oxide nanoparticles. Subsequently, the nanoparticle underwent testing to determine its suitability as an absorbent for heavy metals, specifically lead, as well as its efficacy as an antifungal agent against Fusarium sp. strain. The characterization of nickel oxide nanoparticles involved several measurements, such as scanning electron microscopy analysis, high- and low-resolution transmission electron microscopy, energy dispersive spectroscopy, X-ray diffraction, and hysteresis curve acquisition. The research findings indicate that the extract from hyperaccumulators can be utilized for the synthesis of NiO, which exhibits an absorption capacity exceeding 98% and serves as an efficient antifungal agent against Fusarium sp. pathogens. The approach utilized in this study not only prioritizes "green" and sustainability factors but also takes into account the economic aspects associated with the items being manufactured. The research has important implications in two areas. Firstly, it demonstrates the utilization of natural resources (B. oleracea var. alboglabra) in the production of nickel oxide, which serves as a safer and more eco-friendly substitute for dangerous chemicals. Furthermore, it aids in the advancement of novel techniques for effectively managing biomass hyperaccumulators.

Abstract

The International Criminal Court (ICC) was established to uphold accountability for the most serious crimes such as genocide, war crimes, and crimes against humanity through the principle of complementarity. However, this idealism often clashes with global political dynamics, especially when dealing with superpowers. This study examines the practice of United States hegemony over the ICC through sanctions policies, specifically the implementation of Executive Order 13928 targeting ICC officials related to the investigation of war crimes in Afghanistan and Palestine. Using a qualitative approach based on literature studies, the study finds that the United States' sanctions policy is a form of unilateral coercion and a manifestation of American exceptionalism that strengthens the politics of impunity. These sanctions not only threaten the independence of the ICC apparatus but also have a domino effect on the ICC's legitimacy, authority, and ability to carry out its mandate effectively. These findings indicate that international justice mechanisms remain vulnerable to geopolitical intervention, necessitating the strengthening of legal structures and international cooperation to ensure the ICC can operate without political pressure from powerful states.

Abstract

This research is motivated by the increasing potential for violations of trade secrets by business actors, particularly in the MSME sector, related to information of economic value in the technology and business sectors that is kept confidential. This study aims to understand the legal regulations regarding NDAs as an instrument for protecting trade secrets in Indonesia and Azerbaijan. This research uses normative legal methods and data obtained through library research, analysis of statutory regulations, studies of NDA violation cases in Indonesia, and literature related to the implementation of NDAs in Azerbaijan. The results show that in Indonesia, NDAs are not specifically regulated by law, but have legal force based on the principle of freedom of contract as stipulated in Article 1338 of the Civil Code. Meanwhile, in Azerbaijan, the implementation of NDAs is more effective due to support from government policies and legal institutions that assist MSMEs in maintaining the confidentiality of business information. These findings suggest that strengthening regulations and legal awareness regarding the use of NDAs is necessary to optimize the protection of trade secrets for MSMEs in Indonesia.
