This study aims to identify the problems faced by students in implementing learning. This study used a quantitative approach with a survey method, involving 30 students from two high schools in Yogyakarta. Data were collected through questionnaires about students' learning difficulties, interests, and needs for learning media. The results showed that 96% of the students considered chemistry as a difficult subject to understand because of the abstract nature of the material. As many as 64% of the students felt bored due to the uninteresting presentation of the material, while 72% of the students indicated the need for varied learning methods and interactive learning media to facilitate understanding. The results of the study showed that an innovation was needed to support chemistry learning activities to make learning more active and enjoyable so that it does not lead to student boredom. The developed virtual laboratory media provides flexible, safe and economical simulation of chemical experiments. This application is designed to be accessible without an internet connection using an Android device, allowing students to learn anytime and anywhere. The use of this virtual lab is expected to increase students' motivation, understanding of concepts, and learning experience.

The influence of the development of Science and Technology (IPTEK) on the world of education, so that both teachers and students are required to always adapt to existing developments. Technology is the result of knowledge originating from the world of education therefore the world of education should utilize technology to increase efficiency in learning. Chemistry among students is still considered material that is difficult to understand. One of its attractions is the abstract nature of chemical material. Chemistry learning does not only include theoretical learning but also includes practical activities. This research was carried out to determine the effect of using a virtual laboratory on students' skills during direct practicum. The method used in this research is a quantitative method that uses a lot of numbers, starting from data collection, interpretation of the data and presentation of the results. A total of 52 students in class XI, Department of Mathematics and Natural Sciences at SMA Negeri 1 Sliyeg. Presenting the results in the form of a representative table will increase the reader's level of understanding and make it easier to access information. Virtual laboratories help students understand the practical process. Based on the results of data analysis obtained from filling out the questionnaire, it was found that 78.8% or the majority of students answered agreeing that the virtual laboratory had an effect on increasing pH testing. This proves that the use of virtual laboratories can be a way out so that when doing direct practicum students do not experience difficulties and the practicum runs more effectively.

The development of technology today makes humans coexist with technology. Many human activities can be carried out through the internet network. One of them is the presence of the metaverse which is a technology that contains virtual interactions, digital objects, and decentralized humans from various platforms. Metaverse is used by many people as a medium for buying and selling transactions. Metaverse users generally sell their products in the form of NFTs. Various well-known brands have started promoting their products through the metaverse. The emergence of well-known brands in the metaverse is an opportunity for irresponsible parties to infringe brand rights. As was the case in Ryder Ripps v. Yuga Labs. Pollution, imitation, obscuration, and so forth of well-known trademarks are carried out by irresponsible parties. One of them is the doctrine of Trademark Dilution. Trademark dilution is the unauthorized use by other parties that can weaken the quality or characteristics of a trademark. This makes the question of how the protection of trademarks in the virtual space of the metaverse and what legal action can be taken when there is a violation of trademark rights. Not many countries have regulated the protection of digital trademarks specifically against trademark dilution, as well as Indonesia. This research will be conducted using a non-native juridical approach method with legal sources in the form of laws and regulations, international agreements, theories, and legal rules. The focus of this research is how metaverse with the platform in it can protect the trademark with the terms and conditions agreement of account users in the platform. The result of this research is that brands can be protected against infringement of rights to the brand as well as brand dilution by referring to the terms and conditions of account users listed in the platform. In addition, the legal action that can be taken is to file a lawsuit as determined by the platform and the removal of related content.

Pendidikan vokasi mengutamakan keterampilan siswa, menekankan pembelajaran langsung, dan menyelenggarakan proses pembelajaran teoritis secara lebih efektif. Untuk memenuhi kompetensi mereka di bidang jaringan komputer, banyak Sekolah Menengah Kejuruan (TKJ) memfasilitasi siswa bekerja menggunakan peralatan jaringan secara langsung. Sayangnya cara ini tidak terlalu efisien untuk mengajar di Laboratoriun Jaringan, terutama jika ukuran kelasnya sangat besar ataupun terkendala keterbatasan peralatan/ sarana jaringan komputer.  Tujuan dari kegiatan "Pengabdian Masyarakat Dosen Pulang Kampung IPB" yang dilaksanakan di SMKS 5 Bhinneka Karya Boyolali ini adalah memberikan pilihan praktis dan murah untuk melakukan kegiatan praktikum jaringan komputer dengan cara membuat "Laboratorium Jaringan Virtual". Solusi yang diberikan telah membantu mengatasi masalah keterbatasan perangkat keras dan aksesibilitas yang ada di laboratorium jaringan. Laboratorium Jaringan Virtual memberi siswa kemampuan untuk menerapkan instance virtual perangkat jaringan secara nyata.

Virtual laboratories can provide real learning experiences through computer-aided simulations and activities. Virtual laboratory is rapidly developing its use in science learning because it is proven to provide significant benefits to the process and results of science learning during the pandemic. The limitations of laboratory facilities in genetics learning at the unkhair Biology Education Study program have encouraged the development of virtual practicum strategies and their use in genetic learning with modified free inquiry strategies on the topic of the structure and function of genetic material and reproduction of genetic material. The purpose of this study was to analyze the effectiveness of virtual laboratories based on student perceptions of the use of virtual laboratory applications and to describe and compare these perceptions with the use of laboratory reality and relevant previous research results. There are five aspects of perception surveyed, namely innovation, motivation, effectiveness, benefits, and presentation of practical procedures. This research method uses a quasi-experimental research design for the characteristics and effectiveness of using virtual laboratories and real laboratories in the Genetics course at the Biology Education Study Program, Khairun University, Ternate on the topic of DNA isolation, chromosomes and mitosis. The results of this study indicate that: the characteristics of Blended Learning practicum in the Genetics course in 4th semester students of Biology study program are: 1) instruction-based practicum; 2) practicum based on data collection and reporting of practicum results; 3) practicum based on proof of concept. The effectiveness of the implementation of genetics practicum in laboratory reality and virtual laboratories based on the perception of student responses is more likely to choose reality laboratories than virtual laboratories. The effectiveness of the implementation of genetic practicum based on the results of the practicum report is known to be not significantly different between the results of the practicum in reality and in the virtual laboratory.
