Abstract

This study aims to describe the results of self-assessment in PBL-based learning of mechanical wave material to evaluate students' abilities in carrying out PBL learning activities. This type of research is a mixed-method study with two research methods, namely quantitative and qualitative, and then conclusions are drawn. The data from this study are the results of the pre-test and post-test of critical thinking skills, Self-Assessment assessments. The results of applying self-assessment in PBL-based learning were analyzed to determine the impact on PBL-based learning achievements. Additionally, the pre-test and post-test results of critical thinking skills were analyzed using the Wilcoxon Signed Rank Test to identify significant differences in average and n-gain. From this study, PBL-based Self-Assessment using an assessment instrument in the form of an assessment sheet showed that it could be used optimally in evaluating students' abilities in carrying out PBL learning activities. With the highest student completion in the cycles of “conducting individual and group investigations” and “analyzing and evaluating the problem-solving process,” as many as 91.6% or 33 students.

Abstract

Effect of Soaking Duration Bulb in 75% Old Coconut Water on Growth and Yield of Bima Brebes Shallot (Allium cepa L.): Plant Height, Leaf Count, Bulb Number, Bulb Diameter, and Bulb Weight. Shallot production in Central Kalimantan in 2021 decreased from the previous year due to the lack of application of growth regulators by farmers in addition to fertilizing. The provision of growth regulators from coconut water is one effort to increase crop production. Coconut water contains minerals and growth hormones that are very much needed by plants. Similar research has been conducted previously with 75% young coconut water, but the administration with old coconut water has not been carried out, so it becomes the basis for the research. This study aims to determine the effect of the duration of soaking shallot bulbs of the Bima Brebes variety in 75% old coconut water on the growth and yield of bulbs. The study was conducted in July-October 2023, located in Menteng Village, Palangka Raya City. This study used a 75% concentration of old coconut water with 5 different treatment levels based on a completely randomized design method with 8 replications. Observations and data collection included plant height, number of leaves, number of bulbs, bulb diameter, and wet weight of bulbs. The data obtained were analyzed using Analysis of Variance (ANOVA) and Least Significant Difference (LSD) with the help of SPSS software. The results of the ANOVA and LSD tests showed that soaking shallot bulbs in old coconut water had a significant effect on the number of bulbs (p value = 0.02 <0.05) with P2 = 10.13 and bulb weight (p value = 0.02 <0.05) with P2 = 8.10 g. The results of the analysis of plant height, number of leaves, and bulb diameter had no effect. Soaking shallot bulbs in old coconut water for 4 hours was quite optimal in increasing the number of bulbs and wet weight of bulbs compared to other treatments. Soaking the bulbs for 4 hours was able to increase the number of bulbs by 131% and the weight of bulbs by 169% so that these findings can be applied by shallot farmers in increasing bulb yields. The success rate of this study was greatly influenced by factors and constraints such as high humidity and low sunlight intensity, which can affect bulb development

Abstract

Profiling Self-Regulated Learning and ICT Utilization among Chemistry Education Students in the Digital Era. In the digital era, chemistry education faces dual challenges: fostering students’ self-regulated learning (SRL) while optimizing the use of information and communication technology (ICT). This study aims to profile the levels of SRL and the extent of ICT utilization among chemistry education students, providing insights into how both aspects intersect in supporting academic success. A descriptive quantitative design was employed, involving 26 third-year chemistry education students at Universitas Negeri Makassar. Data were collected through two instruments: an SRL questionnaire covering dimensions of goal setting, planning, time management, learning strategies, self-monitoring, motivation, and self-reflection, and an ICT utilization questionnaire addressing access to digital resources, use of learning applications, participation in online discussions, digital collaboration, and creativity in ICT-supported chemistry learning. Responses were analyzed using descriptive statistics and thematic analysis of open-ended items. The results revealed that students’ SRL abilities ranged from moderate to high, with notable strengths in goal setting, planning, and reflection, but persistent challenges in time management and independent study. In contrast, ICT utilization was consistently high across all dimensions, showing strong reliance on digital resources and collaborative tools. A comparative analysis indicated that students rely more on external ICT support than on internal self-regulatory strategies. The study concludes that while ICT integration in learning is robust, strengthening SRL remains essential to balance technology use with sustainable learning autonomy. These findings suggest the need for instructional designs that deliberately embed SRL-enhancing components into ICT-based learning, aligning with the demands of the digital era and the pursuit of quality education

Abstract

A Systematic Review of Critical Thinking Assessment Instruments in Junior High School Science Education: Trends, Effectiveness, and Challenges. This systematic literature review, conducted using the PRISMA method, synthesizes research on the development of critical thinking assessment instruments in junior high school science education between 2016 and 2025. Secondary data were obtained through the Publish or Perish application with sources from Google Scholar, keywords include science learning, assessment instruments, and critical thinking. By analyzing 7 peer-reviewed national journals, the study evaluates the validity, reliability, and effectiveness of these tools in enhancing students' critical thinking skills. The findings highlight diverse assessment models, their impact on student learning outcomes, and the challenges faced by educators in implementing these tools. This review offers recommendations for improving the design and application of critical thinking assessments in science curricula.

Abstract

Integration of Local Wisdom in the Conservation of Seaweed (Kappaphycus alvarezii) in Tanjung Village, Pamekasan, Madura. Seaweed cultivation (Kappaphycus alvarezii) is the primary source of livelihood for the coastal communities of Tanjung Village, Pamekasan, Madura. This study aims to examine the role of local wisdom in seaweed conservation, including traditional practices that support the coastal ecosystem. The research employed a qualitative approach using semi-structured interviews conducted with 15 key informants, including seaweed farmers, traditional leaders, and village officials. This was followed by a Focus Group Discussion (FGD) with 10 participants from seaweed farmer groups to confirm data and collectively discuss conservation and local wisdom issues. The collected data were analyzed using thematic analysis techniques to establish the relationship between traditional practices and the sustainability of seaweed. The study indicates that the local wisdom practiced by the Tanjung Village community, such as sasi rules (a traditional prohibition system) and traditional planting methods, contributes significantly to the conservation of Kappaphycus alvarezii seaweed. This local wisdom not only preserves the availability of seaweed resources but also strengthens social cohesion within the community. The integration of local wisdom with modern technology has the potential to enhance the effectiveness of conservation and seaweed productivity. Recommendations for advancing the cultivation of Kappaphycus alvarezii in Tanjung Village include: Collaboration between modern science and traditional practices is necessary to develop environmentally friendly and productive cultivation techniques, and the development of a community-based conservation model involving traditional leaders, farmers, and village officials is crucial for sustainable seaweed resource management.
