Abstract

This study aims to analyze the creative thinking skills of primary education’s prospective teachers in science learning. This study uses a descriptive survey to obtain quantitative data without special treatment. The population is students of PGSD Universitas Islam Raden Rahmat for the 2022/2023 academic year who program science courses (125 students). The sample was selected by random sampling technique, which was 84 students. Creative thinking skills are measured by an essay test totaling 8 questions that refer to indicators of fluency, flexibility, originality, and elaboration. The data was analyzed descriptively by calculating the percentage of each indicator to be further adjusted to the level of creative thinking indicator. The results show that students' creative thinking skills is still low in all indicators and included in the non-creative level.  Creative thinking skills on the 'fluency' indicator received ‘enough’, while 'flexibility', 'originality', and 'elaboration' were still at the 'low' and 'very low'.

Abstract

Giving bacteria to microalgae culture can increase the growth of microalgae. Giving aeration can increase oxygen levels in the culture. Good culture conditions can optimize microalgae growth, so the biomass obtained is also higher. The amount of microalgae biomass is directly proportional to the amount of lipids produced. This study aims to determine the effect of the aeration period and the addition of potential bacteria on the growth and lipid profile of Chlorella vulgaris. The aeration periods were 6, 12, 18, and 24 hours. The bacteria used in the co-culture treatment of this study were indole acetic acid (IAA) producing bacteria, amylolytic bacteria, and nitrogen-fixing bacteria from the exploration and identification of several lakes in East Java. Microalgae C. vulgaris co-cultured with IAA, amylolytic and nitrogen-fixing bacteria were given aeration for 6 hours, 12 hours, 18 hours and 24 hours (in different treatment bottles). Microalgae treatment without giving bacteria is done only by giving aeration for 6 hours, 12 hours, 18 hours, and 24 hours (in different treatment bottles). The results showed that there was effect of the aeration period, the culture type, and the interaction between the aeration period and the addition of bacteria on the growth and lipid profile of C. vulgaris. The highest average cell density of C. vulgaris on day 16 was TBA18 mono-culture treatment with an aeration period of 18 hours (26.95 x 106 cells/mL), and BTA co-culture treatment without aeration (12.75 x 106 cells/mL). The harvested biomass of C. vulgaris was used for lipid profile assays. The results of the GC-MS test of TBA18 and BTA treatment showed that the two samples had the same six main compounds but different concentrations. The six compounds are oleic acid, palmitoleic acid, ?-linolenic acid, linoleic acid, stearidonic acid and myristic acid.

Abstract

This study aimed to determine the effect of science, technology, engineering, and mathematics project-based learning (STEM-PjBL) on the collaborative problem solving (CPS) of preservice teachers (PSTs). The pretest-posttest non-equivalent control group design was employed. A total of 72 PSTs enrolled in plant physiology course participated in this study. Self-assessment and project were used to evaluate PSTs’ CPS skills. Self-assessment scores were analyzed by analysis of covariance (ANCOVA), while project scores were analyzed by the Mann-Whitney U test. The results of self-assessment indicated that STEM-PjBL enhances CPS skills, particularly in social regulation, task regulation, and knowledge building. The results of the team’s problem-solving skills in completing the project did not differ between the two groups. But the result of integrated STEM skills showed that the STEM-PjBL group was better at integrating STEM disciplines into their project. This study highlights the importance of interdisciplinary projects in a PjBL environment that can be adopted by teacher preparation programs for enhancing PSTs’ CPS skills as well as gaining knowledge of STEM integration.
