Abstract

This study aimed to develop an animated video-based educational medium on the use of traditional medicinal plants for family health and to evaluate the product validity and initial user responses. The study employed a Research and Development (R&D) approach based on the Thiagarajan 4D development model. The research stages included define, design, develop, and limited disseminate. Product validity was assessed by four validators, consisting of two subject-matter experts and two media experts, while the user response test involved 72 respondents aged 18–50 years in Ternate City. Data were collected using validation questionnaires and user response questionnaires based on a Likert scale, and were then analyzed descriptively in percentage form. The results showed that the material validity reached 92% and the media validity reached 91%, both of which were categorized as very valid. User responses obtained an average score of 81.11%, indicating that the medium was positively received and feasible for use as a supporting educational tool. These findings indicate that the developed animated video met the criteria for content feasibility, language quality, visual presentation, and ease of use at the limited testing stage. Therefore, the developed medium can be used as a means of family health education.

Abstract

The epidermal growth factor receptor (EGFR) is a crucial target in the treatment of non-small cell lung cancer (NSCLC) due to its significant role in tumor cell proliferation and survival. This study investigates the potential of marine-derived compounds from soft coral (Rhytisma sp.) as EGFR inhibitors through molecular docking and pharmacokinetic predictions. Eight compounds identified via GC-MS were docked against the EGFR tyrosine kinase domain (PDB ID: 2ITY) using AutoDock Vina, with Gefitinib serving as the reference drug. The top-performing compounds exhibited binding affinities ranging from –7.0 to –7.4 kcal/mol, closely aligning with Gefitinib's affinity of –7.6 kcal/mol. Notably, 4,12,12-trimethyl-9-methylidene-5-oxatricyclo[8.2.0.0⁴,⁶]dodecane demonstrated the strongest interactions, involving critical residues such as MET793 and LYS745. Pharmacokinetic profiling conducted with SwissADME and pkCSM confirmed favorable drug-likeness and high absorption potential. Toxicity analysis using ProTox-3.0 indicated low toxicity (Class IV) and no predicted hepatotoxicity, carcinogenicity, or mutagenicity. These findings suggest that phytocompounds derived from Rhytisma sp., particularly terpenoid-based structures, present a promising scaffold for the development of EGFR-targeted anticancer drugs.

Abstract

This study aimed to examine students’ responses and compare their learning motivation in ecosystem learning after the implementation of Canva-based interactive learning media among tenth-grade senior high school students. The study employed a descriptive-comparative quantitative approach supported by qualitative data. The participants consisted of 60 Grade X students from three classes. All classes received ecosystem instruction using Canva-based interactive learning media. Data were collected through a learning motivation questionnaire, a student response questionnaire, classroom observations, and interviews. The quantitative data were analyzed using descriptive statistics and one-way analysis of variance (ANOVA), while the qualitative data were used to support the interpretation of the findings. The results showed that students generally responded positively to the use of Canva-based learning media. Students reported that Canva helped them understand ecosystem material more easily, increased their interest in learning, enhanced their enthusiasm in completing tasks, and improved classroom interaction. The statistical analysis also revealed a significant difference in students’ learning motivation among the three classes after the implementation of Canva-based learning media, with Class X-3 obtaining the highest mean score. These findings indicate that Canva-based interactive learning media have strong potential to support students’ learning motivation and create a more engaging and student-centered learning environment in ecosystem instruction. However, the extent of its impact may vary across classes depending on classroom conditions and the learning process.

Abstract

This study aims to determine the resistance status of Ae. aegypti to the deltametrin insecticide in Sumbersari Jember Village. A total of 100 2nd generation female Ae. aegypti were tested using the CDC bottle bioassay with a deltamethrin dose of 10 μg/ml and a diagnostic time of 30 minutes. Molecular detection using AS-PCR was also performed to detect kdr mutations at position 1016 of the VGSC gene. Mortality data was calculated using Ms.Excel with a confidence level of 95%. The molecular wight of the PCR product is calculated using a gel analyzer application.  The results of the CDC bottle bioassay show that the Ae aegypti population is still tolerant to the insecticide deltamethrin (91,25% in mortality rate). However, molecular analysis confirms the presence of a mutation at position 1016 of the voltage-gated sodium channel (VGSC) gene (homozygous mutation), which is known to be the primary target of pyrethroid insecticides. These findings indicate that although phenotypic resistance has not yet fully developed, the mosquito population has shown early indications of target-site insensitivity to deltamethrin, which has the potential to develop into resistance under sustained selection pressure. Further use of deltamethrin insecticide may potentially increase phenotypic resistance, namely a decrease in mosquito mortality after exposure to deltamethrin insecticide. Therefore, an integrated vector control strategy and routine monitoring of mosquito resistance status in the region are required.

Abstract

This study aimed to evaluate the effects of nanopriming using Padina minor nanoparticles on the germination parameters and early seedling growth of Kopay chili pepper (Capsicum annuum L.) seeds, as well as to assess the physiological responses and enzyme activities associated with nanopriming treatment. The experiment was arranged in a completely randomized design (CRD) with five treatments: no priming, hydropriming, and nanopriming at concentrations of 100, 150, and 200 ppm, each with five replications. The observed parameters included time to germination emergence, germination potential, vigor index, root length, shoot length, and the activities of amylase and catalase enzymes. Data were analyzed using analysis of variance (ANOVA) at the 5% significance level, followed by Duncan’s Multiple Range Test (DMRT). The results showed that nanopriming significantly accelerated germination emergence and increased root length, with the best response observed at 100 ppm. However, the treatment did not have a significant effect on germination potential, vigor index, shoot length, or the activities of amylase and catalase during the early germination phase. Thus, Padina minor nanopriming contributes to the improvement of specific early growth parameters, particularly those related to germination speed and root development.

Abstract

This study aimed to evaluate the effects of the dosage and application frequency of chicken bone meal on the growth of water spinach (Ipomoea reptans L.). The experiment employed a factorial design within a completely randomized design (CRD) consisting of two factors, namely chicken bone meal dosage and application frequency. The observed parameters included plant height, number of leaves, and plant dry weight. The results showed that both the dosage and application frequency of chicken bone meal significantly affected the growth of water spinach. A dosage of 60 g produced the highest dry weight, reaching 20.76 g, compared with 6.10 g in the control treatment, while an application frequency of once per week resulted in better plant growth. The interaction effect indicated that the A3B1 combination produced the best growth performance, with dry weight reaching 24.97 g. Therefore, the application of chicken bone meal at an appropriate dosage and frequency can optimize the growth of water spinach.

Abstract

This study aimed to examine the feasibility and effectiveness of a booklet on the rare flora and fauna of the Toba Caldera as instructional material for biodiversity topics. The study employed a Research and Development (R&D) approach using the 4D model, which consists of the Define, Design, Develop, and Disseminate stages. The feasibility of the booklet was assessed based on expert validation, teacher responses, and student responses, while its effectiveness was evaluated using the Mann–Whitney test and N-Gain analysis. The feasibility results indicated that the booklet was categorized as very good based on expert validation. Teacher responses were also rated very good, with a score of 96.25%, and student responses in each trial likewise fell within the very good category. The effectiveness test conducted on students at SMAN 1 Lumban Julu showed an N-Gain value of 0.68, which was categorized as moderate. The Mann–Whitney test indicated a significant difference in ecological literacy knowledge between the experimental and control classes on the posttest, with a probability value of 0.00 < 0.05. In addition, students’ biodiversity ecoliteracy knowledge reached 86.64%, which was classified as high. Therefore, the developed booklet is effective in improving students’ ecological literacy knowledge and is feasible for use as a supplementary teaching material in biodiversity learning by utilizing local potential as a learning resource.

Abstract

This study examines gender-based differences in preservice biology teachers’ perceptions of ethnoscience-based learning, with particular attention to its potential to support equitable learning experiences. Grounded in the perspective of culturally responsive pedagogy, ethnoscience-based learning is assumed to foster inclusivity by integrating local knowledge into science instruction. This study employed a quantitative explanatory design with a cross-sectional approach, involving 28 participants selected through convenience sampling. Data were collected using a validated Likert-scale questionnaire measuring perceived learning quality, suitability to students’ ability levels, and learning motivation. The data were analyzed using descriptive statistics and an independent-samples t-test. The results indicate that ethnoscience-based learning was generally perceived positively, with a moderate-to-high overall mean score (M = 2.98 on a 4-point scale). Male (M = 3.13) and female (M = 2.91) participants reported similarly favorable perceptions. However, the independent-samples t-test revealed no statistically significant difference between the two groups (p = 0.116 > 0.05). These findings suggest that perceptions of ethnoscience-based learning tend to be consistent across gender groups, although such results should be interpreted cautiously given the limited sample size. From a gender perspective, the absence of significant differences in perception indicates a comparable level of perceived learning experience among male and female students, rather than confirming the full realization of gender equity. The findings highlight the potential of ethnoscience-based learning as an inclusive instructional approach, while also emphasizing the need for further investigation using broader samples and more comprehensive indicators of equity, such as participation, access, and learning outcomes. This study contributes to the growing discourse on culturally responsive and gender-sensitive practices in science teacher education
