Abstract

Combination herbal or polyherbal offers advantages by synergizing multiple plants to address health issues more effectively. Meniran and turmeric are traditionally used medicinal plants with notable pharmacological activities due to their bioactive compounds. This study investigated the curative effect of a meniran-turmeric extract combination on immunocompetent cells, particularly NK and CD8 cells, and on liver histopathology in mice administered 7,12-dimethylbenz[a]anthracene (DMBA). Female BALB/c mice (Mus musculus) were injected subcutaneously with DMBA at 45 mg/kg body weight (BW) in the mammary gland area and maintained for eight weeks. They were then treated with a 1:1 meniran-turmeric extract combination for two weeks at doses of 100, 300, 900, and 1,800 mg/kg BW, followed by liver and immune cell analyses. The results showed a lower CD8+ T-cell population in extract-treated groups (17.53±1.13%-19.79±1.51%) compared with the DMBA group (20.92±4.74%). Conversely, NK+ cell populations increased after extract treatment (0.33±0.01%-0.56±0.13%) compared with DMBA alone (0.27±0.02%). Liver histopathology indicated that extract combination administration did not cause more severe damage than that observed in the DMBA group. An extract combination of meniran and turmeric could modulate the immune system, particularly NK and CD8 cells, in mice injected with DMBA. In addition, the study indicated that the combination of meniran and turmeric extract might play a role as an antihepatotoxic agent. This research could serve as a consideration for future studies developing a combination formulation of meniran and turmeric.

Abstract

The purpose of this study is to investigate how biotechnology education focuses on learning implementation, student activities, Science Process Skills (SPS), field constraints, student responses, and to identify future research directions. The study employs descriptive quantitative research involving students at the junior high school Unesa. The data is gathered through observation, test and questionnaire. The data are analysed descriptively. Based on what the observer thought, the data showed that learning went very well. It's mostly made up of talking between students and teachers, like asking questions and having conversations. At most, problem-solving and data collection skills were learned, but things like media, classroom, and time management were not. Student responses were positive to the SETS model, but their understanding of scientific work and evaluation questions needed to be improved. These potentially affect the priority research agenda, which focuses on technology integration, teacher training, contextual learning, interdisciplinary approaches, and the integrated biotechnology of SETS. The study concludes that SETS model learning was carried out very well and received a positive response from students, with active interaction between students and teachers, especially in verbal interaction and SPS, such as formulating problems and data collecting.

Abstract

The current challenge is requiring teachers to be able to implement authentic assessments that support in-depth learning. One of the tools in this implementation is assessment. The problem is that the partner, the MGMP Science Teachers of MTs in Tuban Regency, is not yet accustomed to implementing authentic assessments that support in-depth learning and therefore requires training and mentoring. Based on this, training and mentoring are needed to implement assessments that support in-depth learning. Through this activity, it is hoped that partners can improve their skills in implementing authentic assessments that support in-depth learning. The implementation method is divided into four stages, namely preparation, material presentation, training and mentoring, and evaluation. Participants in this PKM activity were 67 MTs science teachers in Tuban Regency. The results of the mentoring and training showed that (1) there was an increase in the PKM participants' understanding regarding authentic assessments based on pre- and post-test scores; (2) the level of skills of the training participants in planning and implementing authentic assessments was still lacking (thus, more intensive mentoring for participants regarding planning and implementing authentic assessments was needed); and (3) the training participants showed a positive response to the PKM activity.

Abstract

Science literacy in Indonesia is still low based on PISA results, so learning innovations such as the IBSC model of collaborative inquiry are needed to train students' scientific thinking, communication, and collaboration skills. This study aims to analyze the effect of implementing the ecosystem-based Investigation Based Science Collaborative (IBSC) learning model on improving junior high school students' science literacy in food chain and food web material. This study used a quantitative approach with a pre-experimental one-group pretest-posttest design, conducted at SMP Negeri 32 Surabaya in class VII-C with 30 students as samples. The instruments included an observation sheet on the implementation of learning, a science literacy test (pretest-posttest), and a student response questionnaire. Data analysis used the Shapiro-Wilk normality test, Wilcoxon test, N-gain, and descriptive analysis. The results showed that the implementation of IBSC learning was very good, with a percentage of 95.63% in the first meeting and 97.22% in the second meeting. Students' science literacy increased significantly (sig. <0.001), with an average N-gain score of 0.72 (high category), where 68% of students reached the high category and 32% reached the medium category. Improvements were seen in the indicators of explaining scientific phenomena (N-gain 0.69), developing investigation plans (N-gain 0.83), and interpreting data/evidence (N-gain 0.73). Students' responses to active and collaborative learning were highly positive (>85%). In conclusion, the ecosystem-based IBSC model effectively improves students' science literacy through an investigative and collaborative approach, which is applied to the development of meaningful and contextual science learning. This study recommends the sustainability of the IBSC model with a focus on data analysis and expansion of research subjects.
