Abstract

Socializations are generally conducted to improve the societies’ knowledge, learning skill simultaneously with character building and empowerment by illuminating the topics which are relevant to their needs (Ibrahim, Thomas and Fine, 2003; van den Ban and Hawkins, 1999). Mardikanto (1987) stated that socialization can increase the society’s participation on development, especially on chemistry awareness community development. Chemistry is a branch of science which studies about composition, structure, properties and change of matter. Chemistry is generally known as abstract science so that result the chemo-phobia and cause lower chemistry learning interest, especially on students (Leong Suk Yee and Lay Yoon, 2014). This research studies about the advantages of chemistry socialization toward the society in developing affective chemistry domain on students and community. This research quantitatively analyzes 159 data which are purposive randomly gathered from 159 participants (junior and high school students, youth organization, and students of equivalency school). The results show that socialization toward the society develops chemistry affective domain on students reaches 40% - 71% by classifying the relevant examples from daily life, explaining the topic and good responding in discussion, motivating the society and developing the arguments as the conclusion. The achievement of chemistry affective domain on society reaches 75% by accepting the topics of socialization in a good manner, following the suggestions and directions during the socialization, arranging some questions about the topic and interesting on advantages of socialization. The socialization toward the society can be the alternative of learning method to develop the chemistry affective domain. Keywords: education; chemistry affective domain; chemophobia.

Abstract

The need for clean water is a necessity to sustain human life. This need will continue increasing in line with the human population growth, but it is not balanced by appropriate wastewater treatment to preserve the clean water stock. Zirconia and titania-based membrane technology is a promising technology in water and waste treatment processes because it is able to produce a good and stable quality of water against chemical reactions, high temperatures, and mechanical stress. This study aims to literature study-based analyze the capability of synthesis, characterization, and application of a membrane that combines zirconia and titania (Zr1-xTix)O2 with Al2O3 as a substrate for domestic wastewater treatment. The discussion describes the method of zirconia.titania membrane application to support its performance in domestic wastewater treatment.

Abstract

The purpose of this study is to examine how students see studying green chemistry using a culturally integrated project-based learning (PjBL) approach. This study used a qualitative descriptive methodology and was carried out at Don Bosco High School in Jakarta. A saturation sampling strategy was used to choose a sample of 35 tenth-grade science students. Students' written reflections after the PjBL exercises and observations made during the learning process were used to gather data. Data reduction, data presentation, and conclusion drawing were the phases of data analysis. The study's findings show that students' perspectives of studying chemistry have changed from being initially seen as challenging and abstract to being more relevant and significant. While some difficulties with group cooperation were still noted, the majority of students showed active involvement and positive responses throughout the learning process, as evidenced by increased interest, curiosity, and participation in project activities. More than half of the students selected the composting project as their final result, and they were able to connect it to actual environmental problems, especially how organic waste is managed in everyday life and cultural customs. These results show that the use of culturally integrated PjBL promotes collaborative and relevant learning experiences in addition to giving students a more practical understanding of green chemistry principles. As a result, this teaching approach helps students develop more favorable opinions of chemistry and strengthens the link between scientific ideas and practical applications.
