Sutamin 36A, 57126, Surakarta Indonesia 2Department of Chemistry, Universitas Sebelas Maret, Ir. Sutami 36A, Surakarta, 57126, Indonesia Abstract Nanocrystal formulation has limited stability due to a crystal growth particularly formulated into a nano suspension. Therefore, the stabilization of formulation could be conducted by a solid nanocrystal formulation. This present study purposed to formulate the nanocrystal of naringenin, a poor water-soluble bioflavonoid, and incorporated into mesoporous soluble carrier. Naringenin nanocrystal was prepared through a solvent evaporation technique by entrapping the solvent containing naringenin, polymer, and surfactant into a mesoporous carrier. A22 full factorial design was applied to study the effect of Kolliphor EL and Kolliphor P188 as surfactant and polymer, respectively. The solvent was eliminated by evaporation. Furthermore, the solid material was characterized by kinetic solubility, vibrational spectroscopy, thermal analysis, powder x-ray diffraction, and morphological analysis. The results indicated that the naringenin loaded into mesoporous and nanocrystal was obtained. It was confirmed by those characterizations. The naringenin nanocrystal was obtained around 300-500 nm. Increasing the polymer and surfactant concentrations reduced the nanocrystal size. In addition, those parameters inhibited precipitation during supersaturation.

Students^ learning obstacles to the law of conservation of mass material are important to analyze because the material of the law of conservation of mass is fundamental and is related to other chemical materials. The method used in this study is a qualitative descriptive method. The instrument used is the respondent^s ability test and interview guidelines. The research was carried out in a private school in Bandung with the research subject of 27 students of class XI science who had studied the concept of the law of conservation of mass. The findings of this study found that learning obstacles occur because students have misconceptions about the concept of mass, and students are not able to apply the law of conservation of mass in chemical calculations. Students assume that the mass of solid is heavier than the mass of liquid and that the mass of gas involved in chemical reactions is not taken into account.

Chemistry Teacher and Pre-service Chemistry Teacher Views: Can Social Media be Used as Chemistry Learning Media? Ari Syahidul Shidiq1, Sri Yamtinah1, Hayuni Retno Widarti2, Mawardi3 1 Chemistry Education Study Program, Universitas Sebelas Maret, Indonesia 2 Chemistry Education Study Program, Universitas Negeri Malang, Indonesia 3 Chemistry Department, Universitas Negeri Padang, Indonesia Abstract Chemistry learning should be able to integrate contextual chemistry problems and present the sophistication of 21st-century learning technology. Social media, as a product of 21st-century technology, has the potential to be used as chemistry learning media. Therefore, this study aims to investigate the views of chemistry teachers and pre-service chemistry teachers toward the potential use of social media as chemistry learning media. The Purposed-designed survey method that involved 76 chemistry teachers and 109 pre-service chemistry teachers as respondents were used in this study. A total of 40 question items were developed and distributed online using a google form to respondents. Based on the results of the survey conducted, it is known that during online and offline chemistry learning, respondents are accustomed to using YouTube as chemistry learning media. In addition, Instagram is the social media most widely owned by pre-service chemistry teachers, while Facebook is the social media most commonly owned by chemistry teachers. Other results reveal that most respondents have the same screen time, which is more than 4 hours daily. This screen time is used by respondents for entertainment and looking for news information on social media. With this long screen time that has not been used for the learning process, it can be a promising opportunity to use social media as chemistry learning media. This study is expected to be a reference for developing social media-based chemistry learning to increase student motivation and achievement Keywords: Chemistry Learning, Chemistry Teacher Views, Social Media, Instagram Share Link | Plain Format | Corresponding Author (Ari Syahidul Shidiq)
