Abstract

This research aimed to determine how the reading, identifying problem, constructing solution, solving problem, reviewing and extending problem solution (RICOSRE) learning model integration with collaborative mind mapping affects students’ information literacy in higher education institutions. This quasi-experimental study used a pretest-posttest non-equivalent control group design. There were 40 multiple-choice questions selected to assess student information literacy. All instruments have been validated and are reliable. The data were collected from 100 participants who were college students enrolled in the environmental pollution course of the biology education degree program at Siliwangi University, Indonesia. To analyze the research data, analysis of covariance (ANCOVA) was used at a 5% level of significance, followed by the least significance difference (LSD) test. The ANCOVA results showed that the RICOSRE-CMM learning model impacted students’ information literacy. LSD scores were significantly different in terms of students’ information literacy. It can be concluded that the RICOSRE-CMM model could enhance each component of information literacy as these components have been integrated into the learning model syntax, which involves a series of information discovery and analysis processes during group work to find a solution to a problem.

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.
