Abstract

Background: Textbook analysis is very important to assess the quality and suitability of the book. A teacher needs to analyze textbooks so that students can quickly understand the material being taught and read. This study aims to analyze the aspects of scientific literacy presented in the tenth-grade Biology textbooks used at SMAN 1 Kutacane, specifically in the topic of Biodiversity, as contained in two instructional materials: first book, Biology for Public High School/Islamic High School Grade 10 (Merdeka Curriculum, Erlangga publisher), and second book, Biology for Public High School/Islamic High School Grade 10 (Grafindo publisher). Methodology: The research used a descriptive qualitative content analysis method, measuring and comparing the percentage scores of four dimensions of science literacy: Scientific thinking; science as an investigative process; science as a product of knowledge; and the interaction between science-technology, and society. Data were collected from both textbooks and analyzed by calculating the percentage scores for each dimension. Findings: The results showed that Textbook I (Erlangga) had a higher percentage score than Textbook II (Grafindo). The highest dimensions in both books were "science as a way of thinking" (Book I: 61.25%; Book II: 52.50%) and "science as an investigative process" (Book I: 62.50%; Book II: 53.12%). The dimension with the lowest score was "science-technology-society interaction" (Book I: 55.00%; Book II: 48.75%). This book analysis provides empirical evidence about the importance of balancing science literacy dimensions and the need to develop textbooks that improve students' comprehensive science literacy. Contribution: This study provides a comparative insight into how different high school biology textbooks represent dimensions of scientific literacy, offering empirical guidance for improving the balance and depth of literacy components in future textbook development

Abstract

Background: The level of science literacy among junior high school students regarding the human respiratory system remains low, as abstract concepts are difficult to grasp due to the limited learning media provided by teachers. This study aims to develop science literacy-based flipchart media to improve the scientific competence of eighth-grade students at MTsS Al-Washliyah Sei Langgei. Methodology: Using the Research and Development (R&D) framework, the study followed the 4D sequence of Define, Design, Develop, and Disseminate. Subject and media experts, science educators, and 24 students from seventh grade participated in this research. Data collected through expert validation forms, teacher and student practicality questionnaires, and pretest–posttest assessments. The data were analyzed quantitatively through validation percentages and N-Gain to assess effectiveness, as well as qualitatively through descriptive narratives of the comments and suggestions of experts and teachers. Findings: The results showed that the flipchart was highly valid (subject matter experts 96.43%; media experts 98.44%), highly practical (teachers 96.59%; students 98.13%), and effective (N-Gain 0.71). Contribution: These findings confirm that science literacy-based flipcharts are effective in improving students' conceptual understanding and scientific skills, facilitate teachers in delivering material, and can be used as an alternative medium and reference for the development of other science learning media

Abstract

Observations carried out at Senior High School of SMA Ar Rahman found that students' critical thinking abilities were still low, especially in the respiratory system material. The aim of this research is to determine the effect of the problem based learning model on students' critical thinking abilities through practicum on respiratory system material. The samples used were second grade class (XI-MIPA 1) as the experimental-class and XI-MIPA 2 as the control-class. The quasi-experimental research uses a posttest only control design. The variable measured is students' critical thinking abilities obtained from the pretest-posttest scores tested by the t-test. Student practicum activities, student responses, and teacher responses were analyzed using percentage qualitative descriptive analysis. The results showed the average critical thinking ability score for the experimental class was 76.93 while the control was 65.67. The results of the t-test show that there is a significant influence between biology learning using the Problem Based Learning model on students' critical thinking abilities at SMA Ar Rahman High School. The implication is that implementing the PBL model in respiratory system material can serve as an effective pedagogical alternative for educators on SMA Ar Rahman high school to foster higher-order thinking skills in students, which are essential in addressing 21st-century learning challenges. This study provides empirical evidence for the development of a biology learning model based on Problem-Based Learning (PBL) integrated with practicum activities

Abstract

Background: In universities, the availability of bacterial growth media, which is typically synthetic media such as Nutrient Agar (NA), is extremely important for microbiology practicum activities. Nevertheless, in eastern Indonesia, such as Papua, the high cost of commercial media, the reliance on distribution from outside the region, and the limited budget and laboratory facilities frequently present obstacles to access. Currently, there is a significant lack of research on the use of Papuan local food resources as an alternative medium for bacterial growth. Consequently, further research is required to address this gap. The objective of this investigation is to investigate the potential of taro (Colocasia esculenta), a local source of Papuan carbohydrates, as the foundation for the development of an alternative medium for the growth of Escherichia coli bacteria. This is due to the amylose content of 20–25% and amylopectin of 75–80%, which have the potential to serve as an energy source for bacteria. Method: The media was made from taro extract formulated with the addition of agar, glucose, and MSG, then sterilized and inoculated with E. Coli bacteria. The data were analyzed using the parameters of the number of colonies (CFU/mL) with the ALT calculation standard, as well as a descriptive comparison between the control medium (NA) and the taro media. Results: The Taro alternative media is capable of supporting bacterial growth at a rate of 8.3 × 10⁶ CFU/mL, which is approximately 75.5% of the NA media's capacity of 11 × 106 CFU/mL. Although the color of the colonies differs slightly, the morphological characteristics of colonies growing in alternative media are similar to those of colonies in NA media in terms of shape, elevation, size, and edges. Conclusions: These findings indicate that taro has significant potential as a substitute for microbiological media that is based on local resources.  Not only does the utilization of this medium offer practical and cost-effective solutions for laboratory activities, but it also promotes educational independence and innovation that are rooted in local knowledge in restricted regions.  The implications of this research provide opportunities for laboratory independence in the 3T area and promote the utilization of local wisdom for sustainable microbiology research and education

Abstract

Background: Soil contamination occurs when chemical produced by humans pollute and alter the natural conditions of the soil. Contamination caused by heavy metals is very dangerous and can cause harm to the life of organisms through the food chain.  This study aims to determine the effectiveness of biochar and Bacillus sp in reducing Cd heavy metal levels. This study used contaminated soil with Cd levels of 2.59 ppm, pH 7.52, C-organic 1.30%, and CEC 18.35 Cmol/kg. Methodology: The research method used a factorial randomized block design with 2 treatment factors, each consisting of 3 levels: the first factor is biochar dosage, comprising B0 (without biochar), B1 (biochar 20 tons/ha, and B2 (biochar 40 tons/ha) and the second factor is bacterial concentration, comprising C0 (without Bacillus sp), C1 (Bacillus concentration 105), as well as C2 (Bacillus concentration 108). Further analysis if there are different ANOVA results, the BNJ 5% Test will be performed. Findings: the results showed that the combination of biochar 40 tons/ha with bacillus 105 (B2C1) was able to reduce Cd heavy metal levels by 52% over a 4-week incubation period, in addition to reducing heavy metal levels, it also increased soil pH. Cations that are on the surface of the biochar will exchange ions with heavy metals in the soil. Carboxyl –COOH functional groups found in biochar can be released as H+ ions, forming complexes with heavy metal ions and heavy metal ions will be bind to the surface of Bacillus sp. cells containing carboxyl groups, renderingthe the heavy metals unavailable.  Contribution: this study reveals the combination of biochar and Bacillus, where biochar provides an optimal microbial habitat, thuereby increasing remediation efficiency. In addition to knowing the interaction between organic materials with heavy metals and the development of natural and sustainable remediation

Abstract

Background: Coral reef ecosystems in tropical waters are highly productive and biodiverse, with sea cucumbers (Holothuroidea) serving essential ecological functions as detritivores, contributing to nutrient cycling, sediment bioturbation, and substrate quality. Despite their ecological and economic significance, data on the community structure and density of sea cucumbers in Abang Island remain scarce. This study aimed to assess the species composition, density, and ecological patterns of Holothuroidea in the tropical waters of Abang Island, Batam. Methodology: Field surveys were conducted using a transect-quadrat method, with environmental parameters (temperature, salinity, pH, dissolved oxygen) measured in situ. Findings: Five species were recorded: Holothuria leucospilota, H. atra, H. scabra, H. fuscocinerea, and H. pardalis. Species composition was dominated by H. leucospilota at Station 1 and H. fuscocinerea at Station 2. The highest density was 0.130 ind/m² for H. leucospilota at Station 1, and 0.150 ind/m² for H. fuscocinerea at Station 2. Community analysis showed greater diversity at Station 1 (H′ = 1.07) but higher dominance at Station 2 (D = 0.691). Pearson correlation indicated that salinity and temperature were the most influential factors affecting abundance, varying by habitat type. These results suggest that habitat characteristics, particularly substrate and vegetation, shape species distribution in small island ecosystems. Contribution: This study provides the first baseline data on sea cucumbers in Abang Island, offering novel insights into the linkage between environmental parameters and species-specific distribution patterns, and supporting conservation and sustainable management of these ecologically and economically valuable resources

Abstract

Background: Red ginger (Zingiber officinale var. rubrum) is a variant of Z. officinale distinguished by its elevated levels of phenolic compounds—particularly gingerols, shogaols, and zingerone—that exhibit potent anti-inflammatory and analgesic effects. Topical formulations enable localized drug delivery, reducing systemic exposure and minimizing adverse effects commonly associated with oral nonsteroidal anti-inflammatory drugs (NSAIDs). Methodology: Dried red ginger rhizomes were powdered and extracted with 70% ethanol via maceration. The concentrated extract was incorporated into a white soft paraffin–lanolin base to produce ointments containing 5%, 10%, and 15% w/w extract. The formulations were assessed for physicochemical stability, including organoleptic characteristics, pH, spreadability, adhesion, and homogeneity. Anti-inflammatory activity was evaluated using the carrageenan-induced paw edema model in Wistar rats (n = 6 per group), with blank base and diclofenac sodium ointment (1% w/w) serving as negative and positive controls, respectively. Findings: All ointments exhibited stable physicochemical properties within pharmacopeial acceptance limits (pH 5.2–5.9; spreadability 5.6–6.4 cm; adhesion >1 s). In vivo, red ginger ointments significantly reduced paw edema in a dose-dependent manner (p < 0.05). The 15% formulation achieved 60.8% inhibition (0.47 ± 0.05 mL at 5 h), comparable to diclofenac ointment (0.48 ± 0.06 mL; p = 0.71). Contribution: The study establishes that red ginger retains pharmacological activity when formulated into a topical base, confirming its potential as a stable, safe, and effective phytopharmaceutical for localized inflammation management. These findings support further preclinical and clinical studies toward its development as a natural alternative to synthetic topical NSAIDs

Abstract

Background: Diadema setosum is a key species in maintaining coral reef stability through its role in controlling algal growth. However, exploitation for consumption and trade of its gonads by coastal communities has generated anthropogenic pressures that threaten population sustainability. This study aims to assess the population structure and utilisation pressure on   D. setosum in the shallow coral ecosystem of Dedap Island, Batam City. Methodology: Observations were carried out at five stations using a 50-metre belt transect method with 5×5 m quadrat plots. Data were analysed through descriptive statistics to determine density and distribution, while correlation and regression analyses were applied to examine the influence of environmental parameters (temperature, dissolved oxygen, salinity, and pH). Structured quantitative interviews with local fishermen were conducted to obtain information on harvesting practices. Results: The population density ranged from 0.180 to 0.292 ind/m², with a clustered distribution pattern observed at stations farther from human activity. Regression results indicated that temperature significantly increased density, while dissolved oxygen and pH had significant negative effects. Fishermen reported daily harvesting during low tide with yields of 2–3 kg of gonads per person. These findings demonstrate exploitation pressure on D. setosum, underscoring the need for ecosystem-based management. Contribution: The novelty of this study lies in integrating ecological surveys with socio-economic data, offering comprehensive insights for locally adapted conservation strategies.
