Abstract

Sarimukti landfill serves as a waste disposal site. Leachate generated from waste accumulation is discharged through pipelines into multiple retention ponds. This study aims to assess contamination levels in leachate deposits by analyzing the magnetic properties and morphology of magnetic minerals collected from four retention ponds, along with measurements of pH, EC, and TDS in the pond water. Magnetic susceptibility values range from 37.4 – 409.5 (×10⁻⁸) m³/kg, indicating ferrimagnetic mineral dominance. The  values range from 0.81% - 5.96%, where  >2% is often associated to pollutant-contaminated soils. A negative correlation between  and  suggests a minor contribution of superparamagnetic grains from pedogenesis. Scanning Electron Microscopy - Energy Dispersive Spectroscopy (SEM-EDS) analysis identifies spherule and hedral magnetic mineral shapes, with O and Fe as dominant elements and minor Ti, indicating magnetite and titanomagnetite presence. Other elements, including C, Mg, Al, Si, K, Ca, and Mn, likely originate from anthropogenic sources.

Abstract

This study aims to explore the effectiveness of Inquiry-Based Learning (IBL) integrated with the local culture of Hem Re Yegokhe in improving the critical thinking skills of elementary school teacher candidates in a multicultural area. Using an explanatory sequential mixed methods design, this study began with a quantitative pretest–posttest measurement using an instrument based on the five dimensions of the California Critical Thinking Skills Test (CCTST), and continued with qualitative exploration through interviews and observations. A total of 173 students were divided into experimental and control groups. The results showed that the integration of the IBL approach and local cultural practices significantly improved critical thinking skills, especially in the dimensions of interpretation, analysis, and inference. The dimensions of evaluation and explanation experienced a more moderate increase, which was associated with the limited time of the intervention. Thematic analysis supported the quantitative findings and emphasized the role of cultural context in encouraging deep reflection and contextual awareness. The findings also revealed a gap in achievement between students from 3T and non-3T areas, indicating the need for scaffolding strategies and strengthening intercultural competence and social empathy. This study provides an empirical contribution to the development of a locally relevant and socially inclusive cultural-based pedagogical model. Implications include strengthening teacher education curricula, lecturer training, and policies that support the integration of local knowledge as a learning resource. Further research is recommended to be conducted longitudinally, develop culturally based assessment instruments, and explore other cultural practices as learning contexts.

Abstract

The learning environment plays a crucial role in shaping students' motivation, especially in mathematics, a subject that often triggers anxiety and demands high reasoning skills. This study aims to analyze the influence of the learning environment's physical, social, and emotional dimensions on students' motivation to learn mathematics at SMPN 4 Siborongborong, a rural school with unique challenges. Using a quantitative explanatory approach with a cross-sectional design, data were collected from 30 eighth-grade students through adapted and validated instruments: the What Is Happening In this Class? (WIHIC) questionnaire for learning environment and the Academic Motivation Scale (AMS) for learning motivation. Data were analyzed using multiple linear regression with SPSS version 25. The findings reveal that the emotional dimension of the learning environment significantly affects students' motivation (β = 0.347; p < 0.05), while the physical and social dimensions do not show statistically significant effects. The model explains 53.2% of the variation in learning motivation, indicating a strong relationship between the learning environment and student motivation. The results underscore the importance of fostering a favourable emotional climate in the classroom to enhance engagement and reduce math-related anxiety. These findings contribute to developing evidence-based strategies to improve mathematics learning outcomes in rural educational settings.

Abstract

This article aims to explore the challenges and opportunities of implementing green data centres in Indonesia, focusing on regulatory influences, technological advancements, financial implications, and competitive advantages. Primary research was conducted through interviews with key stakeholders, including data centre providers, regulatory experts, energy suppliers, members of the data centre association, representatives from training institutions, and climate and energy economists. Secondary research drew from academic papers, published articles, and industry reports to supplement the findings. The study identified significant challenges in transitioning to green data centres in Indonesia. Key issues include the state electricity company PLN’s reliance on coal for electricity and the limited availability of renewable energy power plants, despite the country’s abundant renewable energy resources. Financial obstacles were noted, such as high initial capital expenditures (Capex) for advanced cooling systems and generators, and high operational expenditures (Opex) for electricity and fuel. However, the adoption of green technologies can reduce long-term Opex by improving energy efficiency. Regulatory gaps and the absence of targeted incentives further complicate the transition to green data centres. Adherence to international standards can provide a framework for sustainable practices, but there remains a significant talent gap in the data centre industry. Strategies to overcome these challenges include adopting renewable energy through Renewable Energy Certificates (RECs), implementing advanced cooling technologies, and utilizing energy-efficient servers and Data Center Infrastructure Management (DCIM) tools. Collaborating with suppliers who meet green criteria is also critical. Transitioning to green data centres offers a competitive edge by attracting clients with green targets and reducing emissions. However, higher initial costs may deter providers, making long-term financial planning essential. This study provides valuable insights for governments and industry stakeholders, emphasizing the importance of sustainable data centre development as part of Indonesia’s journey toward a greener economy.

Abstract

This study aims to analyze the morphological diversity and phylogenetic relationships of six species from the Annonaceae family at the Purwodadi Botanical Garden using a phenetic approach. The background of this research is based on the importance of character-based identification to support taxonomy, conservation, and plant classification within the Annonaceae family, which is known for its high diversity. The research began with field exploration and specimen identification, followed by morphological characterization focusing on stem, leaf, petiole, and flower traits. Data acquisition was conducted by direct observation and measurement using tools such as calipers, rulers, and color tables. The morphological data were analyzed using Hierarchical Cluster Analysis and Principal Component Analysis (PCA) with SPSS 25.00 software to determine phylogenetic relationships among the species. The results revealed two major clusters: the first includes Mitrephora polyprena, Stelechocarpus burahol, Orophea enneandra, and Polyalthia bullata, with a similarity index of 73.2%, and the second consists of Annona muricata and Miliusa horsfieldii, with 59.3% similarity. PCA results indicated that leaf width, leaf length, petiole length, leaf color, and stem surface were the most influential morphological traits. These findings demonstrate that the phenetic approach is effective for analyzing phylogenetic relationships and can contribute to conservation strategies and biodiversity management.

Abstract

Inflammation is the body's physiological response to harmful stimuli, such as infection and trauma, which can lead to tissue damage. The long-term use of synthetic anti-inflammatory drugs has adverse side effects, so safer alternatives to natural ingredients are needed. This study aims to test the anti-inflammatory activity of ethanol extract gel preparations of star fruit leaf (Averrhoa bilimbi L) in mice (Mus musculus). The method used is the method of carrageenan induction on the soles of the feet of mice to observe the effects of inflammation. Gel preparations were administered in various concentrations (5%, 10%, and 15%) and compared with negative controls (gel base) and positive controls (sodium diclofenac). The results showed that the preparation of star fruit leaf extract gel was able to significantly inhibit swelling at concentrations of 10% and 15%. This activity is thought to come from the content of flavonoids and tannins in star fruit leaves which are known to have anti-inflammatory effects. This research provides a scientific basis that star fruit leaf gel preparations have potential as an alternative to natural anti-inflammatory drugs.
