Abstract

This study aims to identify and describe the vegetative morphological characteristics of Nepenthes mirabilis and to measure the abiotic parameters of its habitat in the Lake Gegas area, Musi Rawas Regency, South Sumatra. Data collection was conducted from August 20 to 29, 2026, using a purposive sampling method across five observation stations (P1–P5) representing varying levels of canopy openness and vegetation types. Morphological parameters were analyzed qualitatively and quantitatively, while abiotic parameters were measured in-situ. The results revealed that N. mirabilis in Lake Gegas possesses diagnostic characteristics, including a stem-clasping leaf base and finely ciliated (fimbriate) margins on young leaves. The species exhibits distinct pitcher dimorphism: lower pitchers feature fimbriate wings that guide terrestrial insects, whereas upper pitchers are funnel-shaped without fimbriate wings and supported by twining tendrils for climbing. Leaves are lanceolate to oblong-lanceolate (15–40 cm long, 4–8 cm wide) ranging from light green to yellowish. External pitcher coloration ranges from light green to reddish with dark maroon spots. Abiotic measurements showed air temperatures of 29–31°C, soil temperatures of 28–29°C, relative air humidity of 68–72%, soil moisture of 71–73%, and light intensity of 0.57–0.64 lux. Remarkably, soil pH across sites was near-neutral, ranging from 6.90 to 7.20. The thriving presence of N. mirabilis on neutral substrates under stable microclimatic conditions highlights its eurytopic nature and high phenotypic plasticity. This adaptive capacity enables N. mirabilis to maintain functional carnivorous morphology and optimal growth beyond the typical acidic substrate preferences of the genus Nepenthes.

Abstract

Used disposable face masks can serve as a medium for bacterial growth and a source of environmental contamination. Ultraviolet-C (UV-C) radiation can reduce bacterial counts on used face masks, with radiation duration affecting its effectiveness. This study aimed to determine the effect of UV-C radiation duration of 0, 30, and 60 minutes on bacterial counts on used face masks. An experimental design with three treatments was used: no radiation (0 minutes), 30 minutes, and 60 minutes of radiation. Bacterial counts in four samples were determined using the plate count method on Plate Count Agar (PCA) through the pour plate method and expressed as CFU/cm². The initial bacterial counts on used masks ranged from 1.15 × 10³ to 6.16 × 10⁸ CFU/cm². After 30 minutes of UV-C exposure, bacterial counts decreased to 5.91–5.09 × 10³ CFU/cm², corresponding to a 99.486–99.999% reduction. Extending the exposure duration to 60 minutes further reduced bacterial counts to 0–4.64 × 10² CFU/cm², with reductions of 99.999–100%. UV-C exposure effectively reduced bacterial contamination on used masks, with longer exposure producing greater bacterial reduction. The 60-minute exposure was the most effective duration under the conditions of this study.

Abstract

The use of traditional medicinal plants for postpartum care remains an important aspect of local knowledge among the people of Umauta Village, although it has not been comprehensively documented through scientific research. This study aimed to identify the medicinal plant species, the plant parts utilized, and the preparation and application methods employed in postpartum care. A descriptive qualitative method with a Participatory Ethnobotanical Appraisal (PEA) approach was applied. Data were collected through field observations, semi-structured interviews, plant inventory and identification, and documentation involving 20 informants, including postpartum mothers, traditional birth attendants, family members, and healthcare workers. The findings revealed that the community uses ten species of medicinal plants from several plant families. Leaves were the most frequently utilized plant part (90%), followed by root bark (10%). The preparation methods included boiling, pounding, grating, and direct use, while the remedies were administered orally, applied topically, attached to the body, or used as herbal bathing mixtures. These medicinal plants are traditionally used to accelerate physical recovery, relieve pain, and improve blood circulation in postpartum mothers. The study highlights the significance of the ethnobotanical knowledge of the Umauta community in preserving local wisdom and its potential contribution to the development of evidence-based traditional healthcare practices.

Abstract

The topic of biodiversity is broad and abstract, requiring visual media to bridge scientific concepts with students' real-life experiences at school. This descriptive qualitative study aims to describe students' responses to the use of posters in science learning on this topic. Data were collected through semi-structured interviews with five students purposively selected based on their level of classroom activity out of a total of 14 students participating in the learning process. Data analysis was conducted through data condensation, data presentation, and conclusion drawing, combined with thematic coding. The results showed that students responded very positively to aspects of visual appeal, ease of understanding, relevance to everyday experiences, and increased conceptual understanding. However, students were also critical of the intensity of repeated poster use, particularly regarding the issue of paper waste. All informants were proven to be able to re-explain the concepts of genetic diversity, species, ecosystems, and threats to biodiversity to their peers, indicating an understanding level of AP.

Abstract

Osmosis and diffusion require submicroscopic reasoning that connects chemistry and biology, making these concepts prone to misconceptions among pre-service teachers. This study identified interdisciplinary submicroscopic misconceptions about osmosis and diffusion among Chemistry Education students. A quantitative descriptive survey was conducted using a 15-item four-tier questionnaire administered online to 40 students (17 from class A1 and 23 from class A2). Responses were categorized as understanding the concept, misconception, guessing, or not understanding the concept, based on the correctness of answers and reasons and on confidence levels. The aggregate analysis covered all 15 items (504 responses). Results showed that 61.1% of responses reflected conceptual understanding, 21.6% misconception, 7.9% guessing, and 9.3% no understanding. In addition, 69.4% of students held a misconception on at least one item. Misconceptions were more common for osmosis (25.3%) than for diffusion (17.2%). Prominent misconceptions included viewing equilibrium as a static state, misrelating the net movement of water to changes in potato mass, and believing that osmosis occurs actively. Students were highly confident (92.1% on Tier 2 and 89.3% on Tier 4), even when their answers were wrong, and 78.0% of misconception responses were inconsistent across tiers. These findings indicate that instruction should emphasize the particle model, the dynamic nature of equilibrium, and the connections between chemistry and biology concepts

Abstract

The Indonesian Government's Free Nutritious Meals (Makan Bergizi Gratis; MBG) Program generates kitchen waste that may cause environmental problems if not properly managed. This study aimed to analyze the utilization of MBG kitchen waste for biogas production and evaluate its operational performance. The study was conducted using a 2,000-L biogas digester fed with kitchen waste from the Tamanagung Community Nutrition Service Unit (Satuan Pelayanan Pemenuhan Gizi; SPPG), Cluring, Banyuwangi, Indonesia. The waste was fed at 10 kg/day at a waste-to-water ratio of 1:1, with an inoculum consisting of 20 kg of cattle manure and 20 L of water. The start-up period lasted seven days, followed by 12 days of biogas production and utilization monitoring. The volume of utilized biogas was determined based on the average flow rate recorded every 10 min during stove operation. The results showed an average utilized biogas volume of 500 L/day, with an average flow rate of 5.90 L/min and an average stove operating time of approximately 85 min/day. The average operating pressure reached 80 mbar. These results indicate that MBG kitchen waste can be converted into biogas in quantities sufficient for direct use as an energy source. This utilization demonstrates the potential of MBG waste management for energy recovery and the implementation of a circular economy

Abstract

Collaborative skills are essential for pupils to master in 21st-century learning; however, their application in classroom practice has not yet been optimised. This study aims to describe the collaborative skills of Year 10 pupils through the implementation of a Problem-Based Learning (PBL) model supported by an educational board game at SMAK Sint Carolus Kupang. This is a descriptive study employing data collection techniques such as observation, interviews and documentation. Data analysis was conducted using triangulation to ensure data validity, utilising an interactive analysis model comprising data reduction, data presentation and drawing conclusions. The results of the study indicate that the students’ collaborative skills improved. In the first session, the students’ collaborative skills fell within the range of 50–100, with some still in the ‘fair’ category, whilst in the second session, they predominantly improved to the ‘good’ to ‘very good’ categories (71–100), characterised by increased engagement, a more equitable division of roles, and improved joint decision-making skills. Group observation results also showed an increase in scores from the range of 80–92 in the first session to 88–100 in the second session. It can therefore be concluded that the implementation of the PBL model, supported by educational board games, has a positive impact on improving pupils’ collaborative skills at SMAK Sint Carolus Kupang.
