Abstract

The conversion of agricultural land to non-agricultural uses poses a significant threat to food security, particularly in metropolitan buffer regions such as Bogor Regency. Rapid population growth and economic restructuring have led to a 24.5% reduction in rice field area, declining from 48,177 ha in 2003 to 36,355 ha in 2019, contributing to a regional rice deficit of 37%. This study employs a quantitative spatial approach using Geographic Information Systems (GIS), integrating Spatial Overlay, Cellular Automata (CA), and a Multi-Layer Perceptron Artificial Neural Network (MLP-ANN) to analyze land conversion dynamics and evaluate the effectiveness of spatial planning policies. The results reveal persistent conversion of rice fields, including within designated food crop zones under the Regional Spatial Plan (RTRW), indicating a misalignment between spatial planning and actual land-use dynamics. This study contributes to applied environmental science by demonstrating the value of integrated spatial modeling in assessing land-use policy effectiveness and supporting spatially informed strategies for sustainable agricultural land management and local food security.

Abstract

This study develops and evaluates an instructional model that integrates Guided Discovery Learning with Mathematical Reasoning and Proving (MRP) Tasks to support undergraduate students’ construction of mathematical proofs in Real Analysis. The research focuses on two foundational criteria in instructional development, namely validity and practicality. Expert review involving five specialists produced high Aiken V and ICC values, indicating strong conceptual coherence, structural alignment, and reliability of judgment across components of the model. Practicality was examined through one to one evaluation, small group testing, and a field implementation involving lecturers and students. Across these stages, the model received high ratings for clarity of instructional flow, readability of tasks, feasibility of classroom enactment, and support for structured reasoning processes. The findings demonstrate that the model is both theoretically sound and operationally feasible, providing a coherent pedagogical trajectory that guides learners from exploration toward formal proof construction. This study contributes a validated instructional model and establishes a foundation for future research on its effectiveness and broader applicability in advanced mathematics learning.

Abstract

This study examines the implementation of a digital supervision system based on 21st-century skills using the E-MESp 4Cs Mobile platform as an integrated evaluation–supervision model in primary and secondary schools. The research employed an applied research design within a Research, Development, and Diffusion (RD&D) framework, with a specific focus on the implementation evaluation stage. The study involved teachers, principals, and supervisors from Muhammadiyah schools across four regions, comprising an initial pilot phase in Semarang City and an expanded implementation phase in Semarang Regency, Kendal Regency, and Salatiga City. Supervision was conducted through the integration of three core components: lesson planning, instructional implementation, and student learning products, aligned with the competencies of critical thinking, creativity, collaboration, and communication. The findings indicate a recurring gap between documented instructional planning and classroom practices, while instructional implementation and student learning products based on implementation evaluation data generally demonstrated stronger performance across regions. These results suggest that effective instructional practices are not always adequately represented in formal planning documents. The study concludes that digital, data-based supervision can provide a more comprehensive and reflective representation of instructional quality compared to conventional administrative supervision. Within the scope of this implementation-focused study, the E-MESp 4Cs Mobile platform shows potential to support professional development and evidence-based supervisory practices in 21st-century education.

Abstract

Acid-base material in high school chemistry learning is often considered difficult because of its abstract nature, causing misconceptions and mere memorization in grade XI students. Social media (Instagram, YouTube, TikTok) with 139 million YouTube users and 127 million TikTok users in Indonesia has the potential as an interactive media, but has not been explored multi-platform inquiry-based. This study aims to develop an acid-base e-Module based on an integrated social media inquiry model to improve student creativity and learning outcomes. The quasi-experimental method with a Non-Equivalent Control Group Design was applied to two grade XI classes of MAN 6 Pasaman Barat. The experimental class used an e-Module with a social media link, while the conventional control. Data obtained from the validity and practicality test were analyzed using Aiken’s V formula and practicality percentages.  The validity test result showed a V value of 0.90, indicating a valid category. The analysis of the teacher practicality questionnaire showed an 86% score categorized as very practical, while the student practicality questionnaire showed an 84% score categorized as practical). The t-test yielded a sig (2-tailed) value of 0.02. Based on these results, it can be concluded that the developed e-module is valid, practical, and effective to improve students' creativity and learning outcomes.

Abstract

This study applies an integrated multi-media approach (river water–sediment–shallow groundwater) to assess heavy metal contamination (Pb, Cu, Cd, Fe, and Hg) along the Batang Ayumi River within the influence zone of the active Batu Bola landfill, a setting rarely evaluated in an integrated manner. Samples were collected from four stations (upstream control to downstream) and analyzed using atomic absorption spectrophotometry (AAS). Fe and Pb emerged as the most responsive indicators of landfill influence: Fe increased downstream and was reflected by accumulation in sediments, while Pb showed greater mobility in river water and nearby wells, suggesting transfer from surface transport to shallow groundwater. Cu peaked upstream, whereas Cd and Hg were relatively stable but detectable across media. Although concentrations remained below applicable standards, the spatial patterns indicate persistent environmental pressure that could intensify without improved controls. By integrating evidence across water, sediment, and groundwater, this study clarifies plausible heavy-metal migration pathways from landfill leachate—surface-water transport, sediment retention, and infiltration toward shallow aquifers—supporting targeted leachate management and long-term multi-media monitoring.

Abstract

Surabaya City has a lot of problems with the environment because of excessive urbanization and industrial activities, which include soil, air and water pollution. Among the pollutants of particular concern is heavy metal pollution. One method that can be tried in environmental remediation is phytoremediation, which is the use of plants to restore the environment. The present study focuses on identifying plants in Surabaya that have the capacity to function as heavy metal phytoremediation agents. The present study employs a purposive sampling method in conjunction with a line transect method. The results indicate that 34 plant species possess the capacity to function as effective heavy metal phytoremediation agents. A comprehensive review of the extant literature revealed ten types of heavy metal pollutants with the potential to be accumulated by heavy metal phytoremediation plants in the city of Surabaya, namely Pb, Hg, Cu, As, Fe, Al, Cr, Cd, Zn, and Ni. The diversity index (H') of 2.628, categorized as moderate, and the evenness index of 0.745, categorized as high evenness, indicate that the optimization of phytoremediation plant use can still be maximized by implementing sustainable planting activities as an effective strategy in controlling environmental pollution in large cities such as Surabaya.

Abstract

The development of eco-friendly cosmetics using local bioresources like Uncaria gambir Roxb. (gambir) holds strong promise for sustainable innovation. This study formulates and evaluates a catechin-based solid shampoo enriched with purified gambir extract, aiming to enhance product stability. A 14-day storage test was conducted at 20 °C and 40 °C using three types of packaging: translucent plastic, aluminum foil, and amber glass. Visual observations revealed that higher temperatures, especially in translucent plastic, accelerated color degradation due to catechin instability. Amber glass was the most effective in preserving the shampoo’s original color. Further, aqueous stability was assessed through two wet-use simulations: soaking (full immersion in distilled water) and dipping (partial immersion daily over four days). The shampoo maintained physical integrity during both tests, showing no softening or structural deformation. However, water discoloration increased over time, indicating catechin release and oxidation. The extent of browning was influenced by the pH of the water, suggesting that both environmental pH and oxidative exposure affect catechin behavior during use. These results demonstrate the solid shampoo’s physical resilience and moderate color stability under thermal and aqueous stress. While catechin oxidation is unavoidable, its rate can be mitigated through optimal packaging and pH management. The gambir-based solid shampoo shows potential as a natural, environmentally friendly personal care product, although further formulation refinement is needed to improve color retention during storage and use.

Abstract

Birds are powerful biodiversity indicators due to their wide distribution and responsiveness to environmental pressures. Building on prior reviews, we synthesize methodological advances to update the Multi-species Bird Index (MSI) field. This study recaps limitations like European/breeding-season biases and uncertainty gaps while integrating recent studies that expand analytical rigor. Advances in passive acoustic monitoring, remote sensing, and trait-based models now improve species selection and reduce detectability errors. We translate these into practical guidance for policy application and a research agenda emphasizing seasonal completeness. The synthesis underscores birds’ role as decision ready barometers and provides a blueprint for robust monitoring. Birds serve as premier biodiversity barometers due to their cosmopolitan distribution and sensitivity to anthropogenic pressures. However, traditional Multi species Bird Indicators (MSIs) often suffer from significant Europe-centric and breeding-season biases that limit their global policy impact. This study synthesizes recent methodological breakthroughs to update the MSI framework. We evaluate the integration of Passive Acoustic Monitoring (PAM), high-resolution remote sensing (ALS LiDAR), and trait-based selection criteria into standard monitoring protocols. Our synthesis reveals that combining automated sensor networks with hierarchical Bayesian models effectively mitigates detectability errors and fills critical data gaps in under-represented regions. Furthermore, linking avian indicators with carbon sequestration and equity metrics allows for more robust prioritization of Nature based Solutions (NbS). We provide a practical blueprint for next-generation indicators that emphasize seasonal completeness and statistical rigor. By shifting from retrospective reports to forward-looking policy tools, these refined barometers can more accurately track progress toward global biodiversity targets.
