Abstract

Anthropogenic activities such as land conversion and illegal logging have triggered massive degradation of mangrove canopies, reduced blue carbon stocks, and triggered secondary succession in the form of opportunistic-invasive vegetation invasions such as Nypa fruticans. Conventional field survey-based monitoring faces significant geographical and cost constraints. This study aims to synthesize the development of spatio-temporal satellite data methodologies, identify research gaps in remote sensing sensors, and formulate a monitoring framework for degraded mangroves through several databases. This narrative literature review for the period 2016–2026 was conducted through inclusion and exclusion criteria-based screening of Google Scholar, ScienceDirect, and SpringerLink databases, with 45 selected scientific articles analyzed using qualitative-thematic synthesis techniques. The synthesis results indicate that the integration of long-term temporal data (Landsat and Sentinel-2) on the Google Earth Engine (GEE) platform with machine learning algorithms (such as random forest) is very reliable in tracking canopy damage trajectories. Spatial reconstruction successfully mapped the chronology of Nypa fruticans expansion through three main phases: initiation after upstream disturbance, aggressive colonization of open canopy gaps, and dominance of homogeneous monoculture formations. In conclusion, the use of cloud computing-based time-series satellite imagery is effective in monitoring the dynamics of degradation and opportunistic vegetation expansion chronologically. Future research should focus on multi-sensor data integration architecture (Sentinel-1 optical and radar synergy) and the validation of high-resolution drones to develop a verified early warning system for coastal restoration and carbon balance to support the achievement of SDGs 13 and 15.

Abstract

Contextual biology learning requires locally based learning resources that are easy to apply in research activities. One local resource is coconut water, which contains nutrients and natural growth hormones to support plant growth. This study aims to determine the effect of coconut water on the growth of Aloe vera plants and to identify the optimal concentrations of coconut water for different growth parameters, as a locally based biology learning resource. The method used was a completely randomized experimental design with five coconut water concentration treatments (20%, 40%, 60%, 80%, and 100%) and five replicates per treatment. The growth parameters observed included the number of leaves, leaf height, and root length over a four-week period. The data were analysed using ANOVA and Duncan's post hoc test at the 5% significance level. The results showed that coconut water significantly affected Aloe vera growth (p < 0,05). The 80% concentration produced the highest number of leaves (5,35 leaves), the 100% concentration produced the highest leaf height (11.50 cm), and the 60% concentration produced the greatest root length (3.95 cm). These findings indicate that different growth parameters responded optimally to different coconut water concentrations. These findings suggest that coconut water can serve as an affordable, locally available resource for biology education, enabling students to conduct experimental investigations into plant growth while developing skills in observation, measurement, data analysis, and scientific reasoning.

Abstract

Earthworms are important organisms in the soil ecosystem that play a role in improving soil structure and accelerating the decomposition of organic matter. This study aims to analyze the relationship between soil moisture and the abundance of earthworms (Lumbricus sp.) in the Coban Putri area, Batu City. The method used is descriptive quantitative with a field survey approach through a quadratic plot technique in 30 observation plots divided into three locations based on the distance from the waterfall. Soil moisture was measured using a soil moisture meter with an index scale of 1-10, while the abundance of earthworms was calculated based on the number of individuals in each plot measuring 50x50 cm with a depth of 20 cm. The results showed an average soil moisture of 6.2 and an average abundance of earthworms of 3.5 individuals per plot. Locations near the waterfall had the highest humidity (7-8) with 3-6 individuals of worms per plot, while locations far from the waterfall had the lowest humidity (4.5-5.5) with only 1-3 individuals of worms per plot. Spearman's correlation analysis showed an r value of 0.277 with a p value of 0.139, indicating a weak positive relationship between soil moisture and earthworm abundance and not statistically significant. Soil moisture plays a role in supporting earthworm presence, but their abundance is also influenced by other environmental factors, such as soil pH, temperature, and organic matter content.

Abstract

This study aims to analyze the structure of macrobenthos communities in the freshwater ecosystem of the Mencerit River, East Lombok based on an ethnoecological approach. The study used a quantitative descriptive method with an ethnoecological approach through direct observation and interviews with local communities. Sampling was carried out at four observation stations using a purposive sampling method with three replications at each station. The data collected included the type and number of macrobenthos, water quality parameters, and the results of interviews with the community regarding river conditions and the presence of aquatic fauna. The results showed that 173 macrobenthos individuals were found with a total abundance of 14.42 individuals/m² consisting of 9 species, with the dominant species being Pomacea canaliculata, Radix rubiginosa, and Tarebia granifera. The diversity index (H’) value of 1.98 is classified as moderate, while the dominance index (C) of 0.17 indicates low dominance, so the condition of the river ecosystem is still relatively stable. The EPT value of 2 and the EPT ratio of 13.87 indicate that the water quality is still quite good. The conclusions of this study indicate that the Mencerit River ecosystem is relatively stable with good water quality, supported by the high level of ecological knowledge of the local community in maintaining the sustainability of the aquatic environment through traditional practices.

Abstract

The utilization of Moringa oleifera L., leaf extract as a natural plant biostimulant has attracted considerable attention; however, its effect on the early growth of Allium cepa L., sprouts remains unclear. This study was conducted to assess the effect of Moringa oleifera L., leaf extract on plant growth of Allium cepa L., sprouts and to explore its potential as a local-potential-based biology learning resource. This research applied an experimental approach using a completely randomized design with four different concentrations of moringa leaf extract (25%, 50%, 75%, and 100%) with six replications. The observed parameters were leaf number and plant height at 5, 8, 11, and 14 Days After Planting (DAP). Data were analyzed using one-way Analysis of Variance (ANOVA) at a 5% significance level. The results indicated that different concentrations of moringa leaf extract had no significant effect on the number of leaves (F = 0,080; p = 0,970) or plant height (F = 1,114; p = 0,367) of Allium cepa L., during the 14-day observation period. Nevertheless, the experimental procedure provides a practical and locally relevant learning resource for teaching plant growth and development concepts as well as scientific inquiry skills in biology education.

Abstract

Public demand for premium meat is rising, driving increased consumption of Wagyu and Meltique beef. This study aimed to determine the effect of consuming Wagyu and Meltique beef on cholesterol levels in male mice (Mus musculus). Male mice were selected due to their physiological, anatomical, nutritional, pathological, and metabolic similarities to humans, as well as their common use in cholesterol research. A total of 25 male mice were used in this study, which was conducted from March to April 2026 at the Veterinary Medicine Laboratory (RSHP) of Mandalika University of Education (UNDIKMA). Cholesterol levels were assessed by collecting blood from the tail vein of treated mice on days 7, 14, 21, and 28 using heparinized capillary tubes. Cholesterol levels were measured periodically and analyzed using a one-way ANOVA test. The results indicated that the consumption of both Wagyu and Meltique beef was associated with increased cholesterol levels in male mice. In the Wagyu group, levels rose from 81.22 mg/dL in the first week to 102.00 mg/dL in the fourth week, while the Meltique group saw an increase from 98.33 mg/dL to 123.22 mg/dL over the same period. The study concluded that the consumption of Wagyu and Meltique beef had a significant effect on increasing cholesterol levels in male mice (Mus musculus).

Abstract

Traditional medicinal plants represent a vital component of local wisdom passed down through generations, yet most remain scientifically undocumented. Unlike previous studies on medicinal plant identification that typically concluded at the species inventory stage, this research offers a novel contribution by integrating findings on local medicinal plants into a scientifically validated booklet, thereby enabling its immediate use as an educational resource. This study aimed to identify the medicinal plant species utilized by the community in Gunungsari District, West Lombok Regency, and to assess the validity of the booklet developed based on these findings. An exploratory descriptive method employing both qualitative and quantitative approaches was used. Data were collected from eight villages randomly selected from the sixteen villages in Gunungsari District (Bukit Tinggi, Penimbung, Mekarsari, Jeringo, Ranjok, Kekait, Kekeri, and Taman Sari) through field observations, structured interviews with eight traditional healers (belian) representing each village, and a literature review. The results revealed that the community utilizes 29 species of medicinal plants from various families. The most frequently used plant parts were leaves (48%), followed by rhizomes (28%), flowers (14%), fruits (10%), and stems and roots (3% each). The dominant preparation method was a combination of techniques (62.07%), followed by boiling (34.48%) and pounding (3.45%); the Zingiberaceae family was the most represented group. The developed booklet was deemed highly valid by three validators a subject matter expert, a media expert, and a linguist achieving an average validity score of 88.17%, making it suitable for use as a local wisdom-based educational resource for the community and learners. From a scientific perspective, the results of this study provide baseline ethnobotanical data on medicinal plants in Gunungsari District; these data can serve as a reference for further phytochemical and pharmacological research and as a model for developing educational materials based on local wisdom that can be implemented in other regions.

Abstract

Students' low scientific literacy is evidenced by instruction that remains teacher-centered, a lack of connection between the material and real-life contexts or local culture, and suboptimal initial student proficiency (with pre-test averages of 52.00 for the experimental class and 52.75 for the control class). One alternative approach that can be implemented is the Culturally Responsive Transformative Teaching (CRTT) model based on Ngome local wisdom. This study aims to determine the effect of the Ngome-based CRTT model on students' scientific literacy regarding the topic of ecosystems. The study employed a quasi-experimental design, specifically a non-equivalent control group design. Data were collected via scientific literacy tests. The experimental class utilized the Ngome-based CRTT model, while the control class underwent conventional instruction. Data were analyzed using ANCOVA following the fulfillment of prerequisite analysis tests. The analysis results indicate that the CRTT model had a significant effect on students' scientific literacy, with a significance value of 0.000 (p < 0.05) and an F-value of 30.219. The average scientific literacy score in the experimental class rose from 52.00 to 84.25, whereas in the control class, it increased from 52.75 to 73.50. Thus, the Ngome-based CRTT model positively influences the improvement of students' scientific literacy regarding ecosystem material.

Abstract

Enhancing students' cultural literacy is crucial amidst the currents of globalization that are causing shifts in local cultural values. Conventional teaching methods are considered inadequate for meaningfully integrating local culture into the learning process. Therefore, instructional innovation is needed to combine local wisdom with a deep learning approach specifically, through "ethno-deep learning." This study aims to determine the impact of ethno-deep learning on students' cultural literacy. A quasi-experimental method with a post-test-only control group design was employed. The study population consisted of all Grade X students at SMA Islam Al Azhar NW Kayangan, North Lombok Regency, during the 2025/2026 academic year. A saturated sampling technique was used, meaning the entire population served as the sample; this comprised two classes: a treatment group of 20 students and a comparison group of 20 students. Data collection instruments included a cultural literacy questionnaire and an observation sheet to monitor the implementation of instruction. The data were analyzed using the Mann-Whitney U test to determine whether there was a significant difference in cultural literacy between the treatment and comparison groups. The analysis revealed significant differences between the groups across all dimensions of cultural literacy: understanding cultural complexity, knowledge of one's own culture, and cultural concern. This was evidenced by a Mann-Whitney U test significance value of 0.000 (Sig ≤ 0.1), leading to the rejection of the null hypothesis (H0) and the acceptance of the alternative hypothesis (H1). The study concludes that ethno-deep learning significantly influences students' cultural literacy. This approach proved effective in enhancing students' understanding, awareness, and concern regarding culture through a learning process that is contextual, meaningful, and student-centered.

Abstract

Biology learning on the material of mitosis cell division stage is often considered difficult by students, because the concept is abstract and occurs at the microscopic level. Therefore, learning media are needed that are able to visualize the concept in a concrete, interesting, and meaningful way. This study aims to develop visualization of biology learning in the form of Sasak creative dance art on the material of mitosis cell division stage, as well as to determine the feasibility of the media and students' responses to the developed media. This study uses the Research and Development (R&D) method with a simplified Borg & Gall development model. The product was validated by six validators consisting of biologists, dance experts, and Sasak cultural experts, then tested on a limited basis to 30 biology education students who have studied mitosis material using a purposive sampling technique. The results showed that the media obtained a Content Validity Index (CVI) of 0.836 with a valid category, while the average value of Aiken's V in the biology, art, culture, and general aspects, were 0.800; 0.733; 0.933; and 0.878, indicating that the media meets the eligibility criteria for use as a learning medium. Furthermore, students responded positively to the developed media, perceiving it as helpful in understanding the concept of mitosis and potentially increasing learning interest through visual and kinesthetic learning experiences. Therefore, biology learning visualization in the form of Sasak creative dance is suitable for use as an alternative learning medium that integrates biological concepts with local cultural wisdom.
