A novel niobium oxychloride cluster compound, RbNb6Cl12O2 was obtained by solid state synthesis from stoichiometric mixture of RbCl, Nb2O5, NbCl5 and Nb powder, heated at 675 °C. Its structure was determined by single-crystal X-ray diffraction. It crystallizes in the monoclinic system (a = 6.8097(4) Å, b = 11.6700(9) Å, c = 12.5090(9) Å, ß = 101.337(4) °, V = 974.68(12) Å3, and Z = 2) with the space group of P21/c. The cluster framework of this compound is based on units connected via oxide ligands in the a-direction with two Nb-O linkages between adjacent clusters, which resembles intercluster bonding in Chevrel-Sergent phases. In the other two directions, the linkages occur through single Cla-a bridges. The framework generates channels where the cations Rb+ are located. This compound contains valence electron concentration (VEC) of 15 per cluster unit and therefore exhibits the paramagnetic behavior.

Publisher : Pascasarjana Universitas Negeri Medan

Water hyacinth (Eichhornia crassipes) is one of the potential feedstocks for bioethanol production due to their higher cellulose content. It needs the optimization of pretreatment to remove lignin and release cellulose and hemicellulose from lignocellulosic complex. Pretreatment was done using sulfuric acid, sodium hydroxide, and calcium hypochlorite as soaking agents. Experiment was carried out at 121 °C for 15 minutes. Pretreatment with 1% sulfuric acid decreased lignin by 6.74%, 4.0% sodium hydroxide reduced lignin content by 11.23%, whereas pretreatment with 0.3% calcium hypochlorite removed lignin by 8.30% from original lignin content lignocellulosic substrate. Therefore, sodium hydroxide pretreatment showed highest efficacy in delignification processes, followed by calcium hypochlorite, and sulfuric acid pretreatments.Keywords: Lignin reduction; Lignocellulose; Pretreatment; Water hyacinth

Mandarin berkembang pesat beberapa tahun ini, terutama setelah HSK (汉语水平考试 hàn yǔ shuǐ pínɡ kǎo shì) yang merupakan tes mengukur kemahiran berbahasa mandarin bagi para penutur asing di luncurkan (Julie Yu-Wen Chen, 2022). Sejak diluncurkan tahun 1980, Ujian Standarisasi HSK yang diperuntukan bagi penutur asing memiliki 6 level dimulai dari level dasar yaitu HSK 1 dan HSK 2 , Level menengah HSK 3 dan HSK 4 serta Level tinggi HSK 5 dan HSk 6. HSK 3 yang tergolong tingkat menengah merupakan titik awal kesulitan pembelajarn bagi siswa asing dimana penggunaan bantuan pelafalan mulai dihilangkan. Penelitian akan berfokus kepada analisis kebutuhan dalam proses melakukan pengembangan multimedia interaktif menggunakan aplikasi Lectora Inspire dengan harapan nantinya akan meningkatkan hasil test HSK 3 siswa yang selama ini belajar untuk menempuh test HSK 3. Kemampuan dan kefasihan guru dalam penggunaan peralatan multimedia dan proses pemmbelajaran yang digunakan selama ini berbasis multimedia merupakan fondasi kuat dalam pengembangan produk ke depannya. Kebutuhan siswa yang terbantu pemahamannya dalam pembelajaran HSK 3 menggunakan multimedia interaktif serta meningkatnya motivasi siswa dalam pembelajaran yang menyatakan dengan adanya multimedia interaktif membuat proses pembelajaran lebih menarik dan lebih mudah merupakan motivasi kuat dalam proses pengembangan materi pembelajaran HSK berbasis multimedia interaktif.

The Chinese language has developed rapidly in recent years, especially after the launch of the Hanyu Shuiping Kaoshi (HSK) Chinese language proficiency test. The HSK Standardization Exam intended for foreign students consists of basic levels namely HSK 1 and HSK 2, intermediate levels namely HSK 3 and HSK 4, and high levels namely HSK 5 and HSk 6. HSK 3 which is classified as an intermediate level is the starting point for learning difficulties for foreign students in where the use of pronunciation aids began to be phased out. This study focuses on analyzing the needs of developing interactive multimedia using the Lectora Inspire application to increase the proficiency of students who have been studying for the HSK 3 exam. The ability and fluency of teachers in the use of multimedia equipment and multimedia-based learning processes is a strong foundation in future product development. The results showed that the use of interactive multimedia can help students understand HSK 3 learning and increase student motivation in learning. Students stated that the existence of interactive multimedia made the learning process more interesting and easier. This underlies the development of interactive multimedia-based HSK learning materials.

Education is the foundation of nation development which is crucial in improving the quality of human resources (HR) and competitiveness in the era of globalization. This research compares the education systems of Indonesia and Singapore, which have significant differences in policies and outcomes. The method used is a literature study to analyze the challenges and advantages of the two systems. The research results show that Singapore has a structured and efficient education system, with a focus on the STEM curriculum and developing teacher quality. On the other hand, Indonesia faces the challenges of unequal access, disparities in quality between regions, and a curriculum that is less relevant. This research suggests the need for education reform in Indonesia by adopting best practices from Singapore, including improving teacher selection and training as well as infrastructure investment. Collaboration between government, educators and society is very important to realize quality and equitable education.

This study compares the education systems in Indonesia and South Korea, focusing on compulsory education policies, curriculum, learning methods, and academic pressure. South Korea emphasizes academic achievement, especially university entrance exams, and high use of technology in learning. Meanwhile, Indonesia, through the Independent Curriculum, focuses more on developing student potential, character education, and social awareness. This study uses a qualitative literature review method, analyzing various sources such as academic journals and research reports related to the education systems of both countries. Literature analysis was conducted to explore the geopolitical aspects, education structure, and academic environment of South Korea and their comparisons with Indonesia. The main focus is on education policies, technology implementation, and parental involvement in education. The study results indicate that Indonesia can adopt some of South Korea's approaches, such as better technology integration in learning and increasing the role of parents. The data were analyzed using structured content analysis techniques, which allowed researchers to identify key themes and conclude similarities and significant differences between the two education systems. This study is expected to provide valuable insights for education reform in Indonesia, especially related to improving the quality of education through technology
