Abstract

This study is driven by the persistently low levels of students' critical thinking and decision-making skills, despite the implementation of various student-centered learning models such as Problem-Based Learning (PBL). Previous studies have focused mainly on PBL alone, with little attention to visual tools like the Vee diagram, which can enhance understanding and reasoning by helping students organize and reflect on information. However, the effectiveness of integrating the Vee diagram within the PBL framework in improving critical thinking and decision-making skills among high school students remains underexplored, indicating a research gap. This quasi-experimental study aims to evaluate the effectiveness of Vee diagram-assisted PBL compared to conventional PBL in enhancing students' critical thinking and decision-making skills. The study was conducted with 11th-grade science students at SMA Negeri 1 Lebakwangi, Kuningan. Data collection instruments included a critical thinking test (essay format), an observation sheet to assess decision-making skills, and a questionnaire to capture student perceptions of the PBL approach. Data were analyzed using the Independent Samples t-test. The results indicate that students taught using the Vee diagram-assisted PBL model demonstrated significantly greater improvement in critical thinking skills than those taught with conventional PBL. Decision-making skills were also higher in the Vee diagram-assisted PBL group. A positive and significant correlation was found between students' critical thinking and decision-making skills.

Abstract

Jamu Susut Perut is a traditional Indonesian herbal preparation widely used as a complementary therapy to support weight loss and reduce abdominal fat. It commonly contains medicinal plants such as Guazuma ulmifolia (Jati belanda), Curcuma longa (Turmeric), Zingiber purpureum (Bangle), Murraya paniculata (Kemuning), Orthosiphon aristatus (Cat’s whiskers), Gallae (Majakanis), Areca catechu (Betel nut), and Piperis folium (Betel leaf). These plants are rich in bioactive compounds including flavonoids, polyphenols, alkaloids, and saponins, which possess lipolytic, anti-inflammatory, and hepatoprotective properties that may enhance fat metabolism and lower blood lipid levels. This study aims to identify the phytochemical compounds in Jamu Susut Perut (X) using the Harborne method and to determine its toxicity against shrimp larvae (Artemia salina Leach) through the Brine Shrimp Lethality Test (BSLT). The LC₅₀ (lethal concentration 50%) value was calculated using probit analysis in SPSS and Microsoft Excel. The phytochemical screening revealed the presence of triterpenoids, quinones, flavonoids, and saponins in the herbal formulation. The toxicity test showed that Jamu Susut Perut (X) had an LC₅₀ value of 547.92 ppm, indicating toxicity to shrimp larvae since the value is below 1000 ppm. In conclusion, Jamu Susut Perut (X) contains bioactive compounds with potential pharmacological effects but also exhibits toxic properties at certain concentrations. This research provides scientific data to ensure the safe use of Jamu Susut Perut as a traditional herbal medicine for consumers.

Abstract

Collaboration skills involve planning and working together by considering multiple perspectives, actively contributing, listening, and supporting others. Collaborative activities in learning produce active learning, facilitating an exchange of knowledge and strengthening student understanding. Based on observations, the cognitive learning outcomes of students in class X-K SMAN 1 Turen regarding virus material were incomplete, with an average score of 63. The collaboration skills score is 47.6%, which falls within the beginner category. Therefore, both aspects need improvement. This study aims to improve students' collaboration skills and cognitive learning outcomes about biotechnology through the application of the Group Investigation model. This research is a Classroom Action Research (CAR) conducted in two implementation cycles. The results indicated that through Group Investigation, students' collaboration skills and cognitive learning outcomes improved. Students' collaboration skills increased from a score of 2.9 (basic) in cycle I to 3.2 (proficient) in cycle II. Cognitive learning outcomes also increased from an N-Gain value of 0.53 (medium) in cycle I to 0.74 (high) in cycle II. Based on these findings, the Group Investigation model is recommended as a practical solution for teachers to improve students' collaboration skills and cognitive learning outcomes.

Abstract

Insomnia is a prevalent sleep disorder characterized by dissatisfaction with sleep quality and duration, leading to difficulty initiating sleep, frequent awakenings, early morning waking, and impaired daytime functioning. Non-pharmacological interventions, such as the butterfly hug technique, help improve sleep quality. The butterfly hug involves self-administered positive suggestions to promote relaxation and comfort. These studies examining the effectiveness of the butterfly hug among university students are still limited; therefore, based on the aforementioned background, the researcher is encouraged to conduct this study. This quasi-experimental study employed a nonequivalent control group design. A total of 54 final-year university students were recruited and divided into two groups: an intervention group and a control group. The intervention group received butterfly hug therapy, while the control group did not. The study was conducted over 14 consecutive nights. Insomnia levels were assessed using the KSPBJ-IRS questionnaire. Data normality was assessed using the Kolmogorov-Smirnov test, which revealed a non-normal distribution (p = 0.000 < 0.05). Therefore, the Mann-Whitney U test was used for hypothesis testing. The Mann-Whitney U test revealed a statistically significant difference between the intervention and control groups (p = 0.031, p < 0.05). This finding suggests that butterfly hug therapy was effective in reducing insomnia levels in the intervention group compared to the control group. Butterfly hug therapy has a significant effect on reducing insomnia among university students and may be considered a practical non-pharmacological intervention to improve sleep quality.

Abstract

COVID-19 has significantly affected Indonesia, including East Java and Jember Regency, resulting in high case rates and widespread psychological distress. Social support from RT leaders plays a crucial role in reducing stress, improving mental well-being, strengthening family resilience, and helping prevent transmission through educational, emotional, instrumental, informational, and appraisal support. This study was conducted because research on RT leaders' social support for families of COVID-19 patients and its psychological impact remains largely unexplored. The objective of this study was to analyze the social support provided by RT leaders to families affected by COVID-19. A qualitative design with a phenomenological approach was employed, involving five primary informants and five additional informants through in-depth interviews. The study was conducted from March to November 2021 in Sumbersari Village, Sumbersari District, Jember Regency. The findings of this study revealed that RT leaders played a significant role in providing informational, emotional, instrumental, and appraisal support to the families of COVID-19 patients. Such support enhanced motivation, facilitated recovery, and strengthened psychosocial resilience within the community. This research is expected to enhance families affected by COVID-19's understanding of the social support provided by RT leaders, so that both COVID-19 patients and those with other illnesses may be encouraged to improve their quality of life, particularly their health.

Abstract

Metacognitive abilities are a crucial component of the learning process, significantly contributing to the effectiveness of teaching and learning, particularly in preparing future educators. Practicums, as an integral part of science learning, provide opportunities for pre-service biology teachers to practice their metacognitive skills through the process of planning experiments, solving problems, and reflecting on the experimental results. This study aimed to investigate the metacognitive awareness of biology education students in practicum lectures. The study employed a quantitative descriptive design using a survey method, without any treatment applied to the research object. The survey focused on assessing the metacognitive awareness of biology education students during practicum sessions, categorised into two key aspects: knowledge of cognition and regulation of cognition. A total of 112 students participated in this study, selected using a purposive sampling technique. The Metacognitive Awareness Inventory (MAI) was utilised as the primary instrument for data collection. The findings revealed that the knowledge of the cognition aspect achieved an average score of 80.3, classified as high. Meanwhile, the regulation of the cognition aspect scored slightly lower at 79.7, but is still categorised as high.

Abstract

Problem-solving skills are essential competencies in biology learning, which have a broad and complex scope closely related to real-life phenomena. Students are expected not only to understand biological concepts theoretically but also to apply them in formulating solutions to contextual problems. This study aims to analyse students’ problem-solving skills in biology learning at the senior high school level. The research employed a quantitative descriptive method with a sample of 105 students from SMA Negeri 11 Makassar, selected through random sampling. The research instrument consisted of 16 essay items developed based on eight indicators of problem-solving skills proposed by Greenstein. Data were analysed descriptively by calculating the percentage of achievement for each indicator. The results show that students’ problem-solving skills fall into the low category with an average percentage of 51.62%. The highest achievement was found in the ‘identifies solutions’ indicator (57.50%), while the lowest was in the ‘evaluates solutions’ indicator (47.86%). These findings highlight students’ difficulties in identifying complex biological problems, applying systematic problem-solving steps, evaluating the effectiveness of solutions, and connecting them to real-life contexts. Therefore, students’ problem-solving skills need to be improved through innovative, problem-based, and contextual learning strategies. This study emphasises the significance of active learning approaches in ensuring that biological concepts are not only understood conceptually but also applied meaningfully to address real-world challenges.

Abstract

Water deficiency disrupts metabolic pathways and reduces plant growth. The high demand for Brassica juncea (L.) due to its nutritional value necessitates improved cultivation practices to ensure high-quality yields. Although humic acid is known to support plant productivity, studies examining its interaction with soil moisture levels in B. juncea remain limited. This study aimed to determine the optimal soil moisture level and humic acid dosage for enhancing the growth and flavonoid content of B. juncea (L.). The experiment was conducted using a Randomized Block Design (RBD) with two factors: four levels of humic acid dosage (0 g/kg, 4 g/kg, 8 g/kg, and 12 g/kg) and four watering treatments based on field capacity (FC), namely 20%, 40%, 60%, and 80%, each with four replications. Observations were made 42 days after planting, covering plant height, number of leaves, leaf area, dry weight, and total flavonoid content. Data were analyzed using ANOVA at a 95% confidence level, and significant differences among treatments were further tested using Duncan’s Multiple Range Test (DMRT). The results showed that the treatment combination of 20% FC and 12 g/kg humic acid produced the highest values for growth and flavonoid content of B. juncea L. under drought stress conditions, with plant height (23.67 cm), number of leaves (8 leaves), leaf area (1,022 cm²), dry weight (0.55 g), and total flavonoid content (0.108 mg QE/g sample).
