Abstract

This study aimed to analyze the physicochemical characteristics of soils across different land uses in Jatiroke Village, West Java. Twenty-four surface soil samples were collected from rice fields, plantations, residential areas, and a temporary waste disposal site (TPS) using a stratified random sampling design. Parameters measured included soil color, texture, temperature, pH, electrical conductivity (EC), and total dissolved solids (TDS) through field and laboratory analyses. Principal Component Analysis (PCA) was applied to evaluate parameter relationships and identify dominant drivers of variability. Results showed that rice fields exhibited the highest salinity, primarily linked to the application of nitrogen- and potassium-based fertilizers, while TPS soils were affected by leachate containing organic and inorganic contaminants. Residential areas maintained near-neutral pH and low salinity, and plantations displayed intermediate variability. Descriptive traits such as color and texture varied across land uses but did not strongly differentiate soil conditions. PCA confirmed EC and TDS as the dominant differentiating factors, with pH and temperature contributing secondary variation. These findings demonstrate that fertilizer use and waste leachate are the main causes of elevated soil salinity, emphasizing the importance of monitoring EC and TDS for sustainable land management.

Abstract

This study explores the effectiveness of integrating Argument-Driven Inquiry (ADI) with Science, Technology, Engineering, and Mathematics (STEM) education to improve high school students' argumentation skills on the topic of the human respiratory system. This study was conducted at MTs Negeri 2 North Lampung, using a quasi-experimental design with a non-equivalent group design. The population consisted of 166 students spread across five different classes. From this population, samples were taken, namely students in class VIII 1 as the experimental group and students in class VIII 3 as the control group, through a cluster random sampling technique. The research instrument was a 10-question essay test that had been validated to assess students' argumentation skills. The N-Gain data of the argumentation skills of both classes were shown to be normally distributed. Based on the homogeneity of the data obtained, both had homogeneous variances. Data were analyzed using an Independent Samples t-test and effect size calculation. The results showed that the experimental class achieved a significantly higher increase in argumentation skills compared to the control class (0.46 vs. 0.29, p < 0.05). The large effect size (1.26) confirmed the model's substantial impact. Student feedback was overwhelmingly positive (82.50%). Based on the evidence, it can be concluded that the ADI-STEM learning model effectively improves students' argumentation skills and fosters 21st-century skills by aligning scientific practices with interdisciplinary learning.

Abstract

This study aims to observe Gram-positive bacteria in eco-enzymes produced from the fermentation of peatland plants in Central Kalimantan and to analyze their potential as biotechnology learning resources for developing students’ scientific explanation skills. The research employed a descriptive qualitative method through eco-enzyme preparation, bacterial identification using Gram staining, and analysis of the role of observational results in the learning context. The findings revealed four Gram-positive bacteria, namely Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, and Lactobacillus bulgaricus. The presence of these bacteria demonstrates the active involvement of microorganisms in the fermentation process, which can serve as a concrete example for students to understand biotechnology concepts. These results emphasize that bacterial identification outcomes are not only scientifically valuable but also hold potential as contextual learning resources that support the development of scientific explanation. Through these observational results, students can practice constructing claims, presenting evidence, and connecting them with scientific reasoning. Therefore, this study concludes that exploring Gram-positive bacteria in eco-enzymes derived from peatland plants has the potential to enrich biotechnology learning while simultaneously developing students’ scientific explanation skills.

Abstract

Photothermoelectric (PTE) conversion integrates photothermal and thermoelectric effects, where light irradiation generates a temperature gradient that induces voltage through the Seebeck effect. This study examines the influence of annealing treatment on the structural, morphological, and optical properties of ZnO/SiO₂/Si thin films for PTE applications. ZnO films were synthesized on SiO₂/Si substrates modified via a hydrothermal process, with samples prepared under two conditions: without annealing and with annealing at 700, 1000, and 1100°C. X-ray diffraction (XRD) analysis showed that the unannealed sample had low crystallinity and small grain size, while annealed samples exhibited improved crystallinity and grain growth consistent with the wurtzite ZnO phase. Scanning electron microscopy (SEM-EDX) revealed that annealing transformed irregular, porous structures into more compact and uniform grains, with elemental composition approaching the stoichiometric Zn:O ratio. UV–Vis spectroscopy indicated that annealing broadened the absorption range (330–1100 nm) and reduced defect-related absorption. The enhanced crystallinity and optical absorption imply improved photothermal and thermoelectric potential. Overall, optimizing annealing temperature effectively enhances the light–heat–electricity conversion capability of ZnO/SiO₂/Si thin films for photothermoelectric device applications.

Abstract

The Mataram University campus has shade trees in almost all area units, some of which are still quite ideal and some of which show problems with tree architecture deviations, such as trunk declivity and canopy inclination, which can cause the risk of tree fall. This study was conducted to analyze the distribution of tree fall risk based on tall, trunk declivity and canopy inclination on the Mataram University campus. The sample area was taken using the purposive sampling method and then sampling trees in each sample area unit using the quarter method. Tree variables observed were tall, trunk declivity and canopy inclination. The data were processed respectively to produce tree tall, trunk declivity, and canopy inclination classes. These data were then further analysed in an integrated manner to produce a value of tree-fall hazard risk. These tree-fall hazard values were interpreted into 5 categories, namely not hazardous, somewhat hazardous, quite hazardus, hazardous, and very hazardous. The results show that of the 108 shade trees on the Mataram University campus, 38.01% of the trees were in categories requiring immediate attention or action (moderately hazardous to very hazardous). Zone 1 was the only zone with the highest risk (0.93% very hazardous).

Abstract

Digital transformation in healthcare is a crucial strategy for improving the quality of maternal care in Indonesia, particularly in efforts to reduce the Maternal Mortality Rate (MMR). This study aims to design a digital system architecture for the 2024 MCH Handbook as a means of documentation, early detection, and alarm for pregnancy danger signs that is adaptive to island regions. The research method uses a descriptive qualitative approach with the Framework TOGAF (The Open Group Architecture Framework) as the basis for system design. Data were collected through digital literacy and accessibility questionnaires for pregnant women, in-depth interviews with health workers, as well as Focus Group Discussion (FGD) activities and expert validation from the fields of midwifery, public health, and information technology. The results showed that the digital literacy level of pregnant women was quite good in the information awareness dimension (52.38%), but still low in the information evaluation and application dimension. System accessibility was assessed as high (>50%) in terms of device availability and compatibility. Stakeholders expressed a strong need for a digital MCH Handbook system with danger alarm features, visit reminders, and a simple interface. The expert validation results obtained an average Aiken's V value of 0.88 (valid category), indicating that the system design is clinically, technically, and policy-wise feasible. The developed digital system architecture for the 2024 MCH Handbook is able to address field needs, support local innovations such as SMART ULING , and align with the national agenda for Digital Health Transformation . This system has the potential to be an effective solution to accelerate early detection of pregnancy risks, strengthen the integration of maternal services, and support efforts to reduce maternal mortality in island regions.
