Abstract

The Mentawai Islands, located west of mainland West Sumatra, are part of popp Sumatra Province. The Mentawai people are the indigenous people of the islands and are renowned for their traditional healing practices, practiced by the "gadai mulaggek" (sagei mulaggek). Few published studies on Mentawai plant medicine have been published, most of which indicate that Zingiberaceae is one of the most widely used families. This study examines the traditional knowledge of Zingiberaceae among the Mentawai people of Saumanagnyak Village. Shamans or "gadai mulaggek" were interviewed directlly to obtain firsthand information about treatments using plants from the Zingiberaceae family. This study indicates that six species of Zingiberaceae are used in traditional Mentawai medicine

Abstract

Boon Pring Andeman Ecotourism Area is a developing nature-based tourism destination characterized by bamboo forests, lakes, and natural water sources. However, the ecological quality of this area has not yet been comprehensively evaluated. Bioindicators, particularly aerial insects, can be used to assess ecosystem conditions because they are sensitive to environmental changes. This study aimed to identify the diversity of aerial insects across four habitat types in the Boon Pring Andeman area, namely the bamboo forest, lakeside area, mahogany forest, and mixed forest; to determine insect groups with potential as bioindicators; and to evaluate ecosystem quality. Insects were sampled through field surveys and identified at the family level. The results recorded 23 insect families distributed across the four study sites. Among them, the family Papilionidae showed potential as a bioindicator of ecosystem quality, although further studies are needed to confirm its reliability. Analysis of ecological indices, including the Shannon–Wiener diversity index, evenness index, and species richness index, showed variations among the four habitats, indicating differences in ecological conditions within the Boon Pring Andeman ecosystem.

Abstract

Cattle manure is an organic waste with high moisture content that can slow down decomposition and produce unpleasant odors. Improving composting efficiency can be achieved by adding Trichoderma sp. as a bioactivator. This fungus produces cellulolytic enzymes that accelerate the breakdown of organic matter while promoting water evaporation. This study explored the application of starter incubated on cattle manure substrate and commercial inoculum applied directly, each with three dosage variations (42 g, 38 g, and 10 g) per reactor. The observed parameters included moisture content, pH, and temperature on days 0, 8, and 14 to evaluate the dynamics of the decomposition process. The results are expected to provide preliminary information on the effectiveness of Trichoderma sp. in reducing the moisture content of cattle manure and to serve as a basis for the development of organic waste management technologies through bioconversion.

Abstract

This study aims to analyze the effect of the Project Based Learning (PjBL) model on students’ learning activities and learning outcomes in the Excretory System topic. The study was motivated by the low level of student engagement and learning outcomes associated with teacher-centered instruction, which limits conceptual understanding. A quantitative approach with a quasi-experimental Control Group Design was employed. The sample consisted of an experimental class receiving PjBL instruction and a control class receiving conventional instruction. Data were collected through classroom observations and pretest–posttest assessments. Statistical analyses included the Shapiro–Wilk normality test, Levene’s Test for homogeneity, and Independent Samples t-Test at a 0.05 significance level. The normality test indicated that activity data were normally distributed in the control class (Sig. = 0.329) and experimental class (Sig. = 0.097). Homogeneity testing confirmed equal variances for learning activities (Sig. = 0.623) and learning outcomes (Sig. = 0.506). Hypothesis testing revealed significant differences in learning activities (t = -2.811; Sig. = 0.006) and learning outcomes (t = -5.580; Sig. = 0.000). The experimental class achieved higher mean scores than the control class. These findings indicate that Project Based Learning positively influences student engagement and academic achievement

Abstract

Citronella (Cymbopogon nardus) is rich in absorbing flavonoids, and its precious geraniol is superior, none can be compared. Despite having a number of well-known cultivars of citronella in Indonesia with unique bioactive potential, the expression profiles of genes and geraniol profile content across these plants remain unknown. Here we report on the relative expression of crucial biosynthetic and regulatory genes involved in geraniol production, analyzed in relation to β-carotene levels and geraniol content measured from five different Indonesian citronella cultivars. Gene expression was quantified using real-time quantitative PCR (RT-qPCR), targeting nine genes: CnDXS, CnIDI, CnGPPS, CnGES, CnLIS, CnUGT, CnMYB, CnGEDH, and CnGDP. Geraniol content was determined according to High Performance Liquid Chromatography (HPLC). Citrona 1 Agribun and Citrona 2 Agribun showed higher expression of the upstream biosynthetic genes (CnGES, CnGPPS) and the regulatory gene CnMYB for which showed also good linearity with highest geraniol 24.71 mg/L and 26.35 mg/L, respectively. These results demonstrate a positive expression levels and geraniol content, highlighting the transcriptional complexity in citronella geraniol biosynthesis. The conclussion, suggest possible molecular candidates for enhancing contents in biofortification scenarios (e.g., selective breeding or genome editing) for essential oil quality.

Abstract

This study examined the effect of Cooperative Integrated Reading and Composition (CIRC) assisted by mind mapping on students’ problem-solving skills in the context of environmental change. A quasi-experimental non-equivalent control group design was conducted with 74 tenth-grade students at a senior high school in Garut, Indonesia. The experimental group received CIRC combined with mind mapping, while the control group experienced teacher-centered instruction. The results showed no significant difference at the pre-test stage, indicating comparable initial abilities. However, the experimental group demonstrated significantly higher post-test scores, with a very large effect size (Cohen’s d = 1.31). A dimensional analysis revealed that the intervention enhanced students’ ability to clearly identify environmental problems, explain cause and effect relationships, and predict ecological consequences. The most substantial improvement was observed in generating and justifying solutions, where students produced more feasible, creative, and scientifically grounded responses. These findings suggest that integrating CIRC with mind mapping effectively supports the development of higher-order problem-solving skills. This approach promotes deeper analytical thinking and equips students to address complex socioscientific issues, highlighting its value as an innovative strategy in biology education

Abstract

Developing students’ numeracy literacy is an important goal in science education, particularly for understanding environmental phenomena that require data interpretation and quantitative reasoning. However, classroom learning often provides limited opportunities for students to analyze environmental issues using scientific evidence and numerical information. This study aimed to develop ASICC-based student worksheets integrating Socio-Scientific Issues (SSI) on environmental change topics to strengthen students’ numeracy literacy. The study employed design research using a development study approach based on Tessmer’s formative evaluation model, consisting of preliminary study and formative evaluation stages, including self-evaluation, expert review, one-to-one evaluation, small group evaluation, and field testing. The participants were 36 tenth-grade students at SMA Negeri 1 Prambon. Data were collected through observations, interviews, and expert validation sheets and analyzed using descriptive quantitative methods. The validation results indicated that the developed worksheets were categorized as valid to very valid, with scores of 73%, 98%, and 93% from experts and practitioners. Learning activities structured through the ASICC stages encouraged students to analyze environmental issues, interpret data, and formulate evidence-based solutions. These findings suggest that ASICC-based worksheets integrated with SSI have the potential to strengthen students’ numeracy literacy in environmental change learning.
