As a plant that is easy to grow, banana tree (Musa spp.) is an abundant tree in tropical countries. Banana tree is only able to bear fruit once in its lifetime and the waste of banana pseudo-stems are also existed in a large number. The cellulose content in the banana pseudo-stems can be utilized as a source of raw material for the manufacture of nanocellulose. This study aims to develop teaching strategy which introduce the process of nanocellulose isolation from banana pseudo-stem through a dissolve method using ionic liquid. The research method is the content analysis using the content validation format as the research instrument. The isolation process involves several school chemistry concepts as such as water evaporation, hydrolysis process, factors influencing reaction rate, intermolecular interaction, and colloid. Thus, this context has a potential to be integrated into school chemistry learning. Beside it, this context also has a potential to introduce the principles of green chemistry except catalysis principle.

Entering the digital era, communication and information technology continues to experience development. Therefore the development of these technologies must be adopted and utilized for educational purposes. The availability of teaching materials in the sample environment under study is still very limited, existing learning resources are still general in nature and still contain concepts with conventional formats. The purpose of this study was to determine the need for website-based learning for vocational students. The research sample was taken using Purposive Sampling as many as five Chemical Engineering students. Data collection is done by semi-structured interview methods, unstructured observation and field documentation to determine the urgency of the need for web-based teaching materials. The research instrument was the researcher herself with the help of interview guides. The collected data is then analyzed using Miles and Huberman's analysis theory, then triangulated to find out its validity. Based on the triangulation results from the three data, students are very interested in web-based learning. This research is expected to provide recommendations to policy makers to be able to meet the needs of web-based teaching materials for vocational students to improve their learning outcomes.

Various separation techniques for separation of technetium-99m (99mTc) from molybdenum-99 (99Mo) are being developed to overcome the drawbacks of using 99Mo from neutron activation technique. Ionic liquids (ILs) were used in many extraction processes in metal separation due to their high selectivity. In this research, two benzotriazolium-based ionic liquids were used as co-extractant in 99mTc/ Mo separation process via liquid-liquid extraction. 1-octyl-3-methyl-benzotriazolium iodide ([MeOcBtu]I) and 1-octyl-3-methyl-benzotriazolium bis (trifluoromethanesulfonyl) imide ([MeOcBtu]TF2N) were successfully synthesized and analyzed by FTIR, 1H-NMR and 13C-NMR. Extraction processes were conducted in various organic solvents, pH, and extraction time without/ with ionic liquids addition. The data of ratio between 99mTc distribution coefficient compared to Mo distribution coefficient showed that the addition of ionic liquids exhibited significant improvement of separation factor. The separation factor of extraction using conventional water immiscible solvent ranged between 0 – 8 and increased to 30 – 600 as ILs were added. The optimum conditions which achieved highest separation factor were pH 14 using [MeOcBtu]I-chloroform. Benzotriazolium-based ionic liquid potential to be developed as extractant in the separation of 99mTc from 99Mo. Keywords: Ionic liquids, benzotriazolium, technetium-99m, molybdenum, liquid-liquid extraction.

The problem in this research is that students are more familiar with the application of metallic bonding than its concept. This is because the characteristics of the concept are abstract concepts with real context. It makes students more interested in studying the phenomenon but lack to explain the concept and some students show misconception. Therefore this research aims to design learning sequences of metallic bonding topics using the framework model of educational reconstruction (MER). This sequence considers the students’ and scientists’ conception. Considering the initial conception of students in designing learning sequences provides benefits for students. Through MER, learning sequences begin by analyzing student conceptions through semi-structured interviews and concept maps designed by students. Scientific conception analysis is done through concept analysis of several text books that are often used in learning. There are three criteria of students’ conception they are prefer to scientist conception, misconception, and incompetence. Based on the three criteria, learning sequences are produced with the aim to bringing students' conceptions toward scientific conceptions.
