Enhancing high-order thinking abilities through disc socio-scientific issues discussion on the virus concept
Based on national and international assessments, Indonesian students' higher-order thinking is inadequate, highlighting the need for effective learning. This study aimed to explore the impact of discussion of a socio-scientific issue on the development of higher-order thinking related to the concept of viruses. A quasi-experimental design used a nonequivalent pretest and posttest control group framework. The experimental group engaged in a socioscientific issue discussion model comprising the stages of Polemic, Exploration, Action, and Conclusion (PEAK). In contrast, the control group was instructed with a constructivist learning approach with discussion, students' presentations, and teacher explanations. The experimental group included 26 males and 46 females, while the control group had 30 males and 41 females. The findings showed that the experimental group's average pretest score was 55.1, while the control group's was 60,1. After the intervention, the experimental group achieved a posttest average of 73,3, compared to 69 for the control group. The N-gain test results demonstrated higher average gain in the experimental group (x-gain 0,5) than the control group (x-gain 0,2). Additionally, the Mann-Whitney U test indicated a significant effect of the socioscientific issue discussion learning model on students' HOTS. This model offers a promising alternative to enhance students' high-level thinking.

Isolation and characterization of phosphate-solubilizing bacteria in land managed with the dusung system
Soil microorganisms play a crucial role in nutrient cycling and soil fertility, particularly through their ability to solubilize insoluble phosphate compounds. This study aims to isolate and characterize phosphate-solubilizing bacteria (PSB) on land managed under the dusung agroforestry system. Soil samples were collected from five types of land use: forests, mixed orchards, clove hamlets, nutmeg orchards, and shrubs. PSB isolation was performed using Pikovskaya medium with the spread plate method, followed by characterization of colony morphology (shape, edge, color, elevation) and Gram staining. The results showed that the highest PSB population occurred in forest land (8.3 × 10? CFU/ml), followed by mixed orchards (6.2–6.7 × 10? CFU/ml), clove orchards (5.3–5.4 × 10? CFU/ml), nutmeg orchards (3.2–5.6 × 10? CFU/ml), and the lowest in shrubs (7.1 × 10³ CFU/ml). The characteristics of PSB varied, with isolates from forests and nutmeg orchards predominantly consisting of coccus-shaped Gram-positive bacteria, while those from mixed and clove orchards were dominated by bacillus-shaped Gram-positive bacteria. The population and diversity of PSBs were influenced by the availability of organic matter, soil pH, and land management practices. These findings highlight the ecological importance of the dusung system in sustaining soil fertility and promoting ecosystem resilience.

Advances in diabetes intervention: Targeting hormonal regulation, hIAPP, glucose transport, and key enzymatic pathways
Diabetes mellitus is a chronic metabolic disorder characterized by persistent hyperglycemia resulting from impaired insulin secretion or action. This condition remains a leading cause of global morbidity and mortality and is closely associated with various metabolic complications and cancer risk. This study aimed to identify potential molecular targets and hormonal regulatory mechanisms involved in diabetes management. A systematic review was conducted by searching indexed scientific articles in databases such as ScienceDirect and Google Scholar using the keywords “diabetes,” “molecular targets,” “insulin sensitivity,” and “hormonal regulation.” The analysis identified six major molecular mechanisms contributing to improved insulin action and glucose homeostasis, involving targets such as human islet amyloid polypeptide (hIAPP), ?-glucosidase, dipeptidyl peptidase-4 (DPP-4), sodium-glucose co-transporter-2 (SGLT2), glucose transporter type 4 (GLUT4) translocation, RNA-binding proteins (RBPs), and key enzymatic pathways associated with glucose metabolism. The development of therapeutic approaches directed toward these pathways could significantly enhance diabetes control, improve insulin sensitivity, and prevent long-term complications.
Remap NHT learning model integrates scientific literacy and critical thinking to enhance students creative thinking
Students' scientific literacy skills help them analyze and evaluate each scientific subject. It is predicted that scientific literacy skills will help students improve their communication abilities as well.

The study was quasi-experimental since it employed a non-equivalent pretest-post-test control group design and included 122 eleventh-grade students at SMAN 4 Soppeng during the 2023/2024 academic year. The participants were divided into three groups. An essay test assessed every variable. The findings indicated that (1) there was a significant correlation between scientific literacy skills and creative thinking skills; (2) there was a significant correlation between Critical thinking skills and creative thinking skills; and (3) there was a significant correlation between scientific literacy skills and Critical thinking skills. The regression equation showed Y= 0,228*X1+0.995*X2+21,645. Based on the findings, it can be concluded that Remap-NHT can be utilized to improve students' scientific literacy, communication, and creative thinking skills, all of which are demonstrated to be connected.
Study of dogania subplana aclimatization in the turtle learning center university of bengkulu
The forest softshell turtle (Dogania subplana) is a species increasingly threatened by habitat destruction and overexploitation. This study aims to identify the acclimatization process of D. subplana in an artificial environment, specifically, an aquarium at the Turtle Learning Center (TLC). The research was conducted over 30 days from July to August 2024. Observations were made on daily behavior, body temperature, and health condition, individual biometric measurements, and environmental (abiotic) parameters. The results showed that daily behaviors such as feeding, basking, and hiding occurred regularly, indicating the species' ability to adapt to a new environment. The turtles experienced an increase in body weight, while growth in carapace length and width was very slow. The body temperature of D. subplana varied in accordance with the surrounding environmental temperature, reflecting its dependence on ambient conditions. Some individuals experienced minor health issues, such as fungal infections, but the majority remained active and healthy. Environmental factors such as temperature, humidity, pH, dissolved oxygen, total dissolved solids, and light intensity were within ranges conducive to acclimatization. These findings suggest that the aquarium at the TLC is quite effective as an ex situ conservation facility in supporting the adaptation process of D. subplana outside its natural habitat.

Integrating STEM education and socio-scientific issues: Impacts on student creativity
Creativity is an essential 21st-century skill that students must develop to solve real-life scientific and environmental problems. This study aims to determine the effect of the STEM-Socio Scientific Issues learning model on students' creativity in the concept of organic waste management. Students' creativity is measured based on four indicators according to Torrance, namely fluency, flexibility, originality, and elaboration. This study uses a quasi-experimental method with a non-equivalent control group design. The research subjects consist of two classes at Muhammadiyah High School in Sukabumi City. Data were collected through creativity tests in the form of pretest and posttest essay questions that had been validated and reliability-tested. The results showed that the STEM-SSI learning model significantly improved students' creativity, particularly in the aspects of fluency (N-Gain 0.4031), flexibility (0.3029), and originality (0.3017), with a moderate category. However, on the elaboration indicator, the control class achieved a slightly higher N-Gain score (0.3574) compared to the experimental class (0.3396), indicating that this aspect has not developed optimally in STEM-SSI learning. Nevertheless, since three out of four creativity indicators showed significant improvement in the experimental class, it can be concluded that STEM-SSI learning can enhance students' creativity, particularly in terms of fluency, flexibility, and originality.

Community structure and exploitation pressure of giant clam in dedap island-abang waters batam
The community structure of Tridacnidae in the shallow coral waters of Dedap Island, Batam, has been analysed through a quantitative approach to reveal ecological dynamics and exploitation pressures from the surrounding communities. This study employed transect methods and ecological index analysis, including Shannon-Wiener diversity (H?), evenness (E), and Simpson's dominance (D) across five observation stations. The results indicate a high dominance of Tridacna crocea in locations with low exploitation pressure, whereas T. maxima and T. squamosa, which are still hunted by the local population, exhibit limited abundance. Pearson correlation revealed that dissolved oxygen (DO) has a strong positive relationship with H? and E, and a negative relationship with D, while temperature showed an inverse relationship. The integration of ecological analysis with socio-ecological factors revealed that anthropogenic exploitation pressures also shape community structure spatially. This study offers a holistic approach to the conservation management of Tridacnidae based on community participation and habitat zoning, while simultaneously addressing gaps in ecological and social research in the coral reef areas of western Indonesia.

Correlation of cognitive learning outcomes and creativity in PjBL with culturally responsive teaching
Learning in the 21st century emphasizes higher-order thinking skills, particularly creativity and cognitive ability. However, observations in biology learning indicate that students’ creative thinking and conceptual understanding remain low, especially in biotechnology material. This study aims to determine the correlation between cognitive learning outcomes and creativity through the implementation of the Project-Based Learning (PjBL) model with the Culturally Responsive Teaching (CRT) approach. The research employed a quantitative correlational design involving 72 students of Grade X at SMA Negeri 1 Depok, Sleman, Yogyakarta. Data on creativity were collected using a validated creativity rubric, while cognitive learning outcomes were obtained from post-test scores. Data were analyzed using the Pearson product-moment correlation test with SPSS. The results showed that there was no significant correlation between cognitive learning outcomes and creativity (r = 0.090; p = 0.455 > 0.05). This finding suggests that an increase in cognitive learning outcomes does not necessarily lead to an increase in creativity. Thus, although the implementation of the PjBL-CRT approach contributed positively to students’ learning experiences, cognitive and creative abilities tended to develop independently. These results suggest the need for further learning strategies that explicitly integrate creative processes into cognitive learning tasks in biotechnology education.

Variation of morphological response of cayenne pepper cultivars to phenoxaprop-p-ethyl herbicide
In the cultivation of cayenne pepper (Capsicum frutescens L.), there is a problem with weeds. The use of herbicides for weed control can also trigger phytotoxic reactions in cultivated plants. The purpose of this study was to determine the morphological response of various cultivars of cayenne pepper to exposure to the Phenoxaprop-p-ethyl herbicide. This study employed a completely randomized design. The research data were analyzed using ANOVA and Kruskal-Wallis statistical tests. The study's results revealed a strong biphasic (hormesis) response pattern, where a dose of 55 g/L triggers growth, while a dose of 110 g/L causes phytotoxicity. .
Effect honje forest fruit juice administration on hemoglobin levels following mercury chloride treatment in mice
Exposure to mercury chloride (HgCl?) is known to induce oxidative stress, which negatively affects the hematological system, including a decrease in hemoglobin levels. This study aims to analyze the effect of honje fruit juice (Etlingera hemisphaerica), known for its high antioxidant content, on hemoglobin levels in mice (Mus musculus) exposed to mercury chloride. This study used an experimental method involving several groups of mice, namely group K1 (control), group K2 (given honje fruit juice), and group K3 (injected with mercury and given honje fruit juice). Hemoglobin levels were measured using a Sahli tube. The results showed that honje fruit juice significantly increased hemoglobin levels in mice exposed to mercury chloride compared to the control group. These findings indicate that the antioxidant content in honje fruit can help reduce the toxic effects of mercury chloride on the circulatory system. Therefore, honje fruit juice has the potential to be developed as a natural therapeutic agent in efforts to mitigate the toxic effects of mercury chloride.

BioDiv-Web: Integrating structured project-based learning with citizen science to enhance critical thinking and environmental literacy
The escalating global biodiversity crisis underscores the critical need for effective educational strategies that promote environmental awareness and competencies. This research and development study addresses this imperative by designing and evaluating "BioDiv Web," an innovative e-learning platform for biodiversity education. The platform synergistically integrates the Structured Project-Based Learning (SPjBL) model with a Citizen Science Project (CSP) approach to create an authentic and scaffolded learning environment. Developed using the Lee and Owens model, the product was validated by experts and deemed highly valid (e.g., material validation: 100%) and practical (average score: 92%) based on trials with students. A quasi-experimental study involving 70 tenth-grade students was conducted to assess its effectiveness. The experimental group exhibited significantly higher learning gains compared to the control group. The results demonstrated moderate effectiveness, with normalized gain scores of 0.68 for critical thinking skills and 0.65 for environmental literacy. One-way ANCOVA analysis confirmed that these improvements were statistically significant (p < 0.001). The findings affirm that the BioDiv Web platform is a robust, practical, and effective digital tool for enhancing senior high school students' critical cognitive and affective learning outcomes in biodiversity education.

Ethnobotany of spice plants among the community of emparu baru village, dedai district, sintang regency
The people of Emparu Baru Village still maintain local wisdom, including the traditional use of herbs and spices as cooking spices. However, this local wisdom is still passed down orally and has not been documented in writing. This study aims to identify and document the diversity of spice plants used by the Dayak Desa community in Emparu Baru Village, Dedai District, Sintang Regency. The research employed a qualitative descriptive method with an ethnobotanical approach. The results show that the Dayak Desa people possess extensive knowledge of various types of local spice plants, including rhizomes, leaves, tubers, fruits, seeds, and others. This traditional knowledge not only plays an important role in maintaining the resilience of local species but also holds great potential to be developed as a valuable source of information for efforts to conserve plant biodiversity. Based on the ethnobotanical study of spice plants, it can be concluded that there are 42 plant species from 25 families used as spices for cooking. These spices are derived from various plant parts, including fruits, stems, seeds, flowers, leaves, young leaves, bark, rhizomes, tubers, bulbs, and shoots.
