Abstract

This study investigates the effectiveness of the experimental method, specifically using hydroponic techniques, in improving student learning outcomes in primary school science education. A quasi-experimental design with pre-test and post-test measures was employed, involving two groups of sixth-grade students from MI NU Tamrinut Thullab Undaan Kudus, Indonesia. The experimental group engaged in hands-on hydroponic activities, while the control group received traditional lecture-based instruction. The results indicate a significant improvement in the experimental group’s post-test scores (M = 89.31) compared to the control group (M = 74.33), with statistical analysis revealing a t-value of 5.85 (p < 0.05). Qualitative feedback from students further supports these findings, as they reported increased motivation and a deeper understanding of scientific concepts through the experimental method. This study highlights the potential of inquiry-based, hands-on learning to enhance student engagement and performance, especially in resource-limited educational settings. The findings suggest that integrating experimental methods into the science curriculum can significantly improve learning outcomes and should be considered in future educational reforms. However, the study's limitations, including a small sample size, indicate the need for further research to replicate these findings in diverse contexts.

Abstract

Problem-Based Learning (PBL) has been widely recognized as an effective pedagogical model for improving students’ understanding of science by encouraging active engagement, critical thinking, and problem-solving. This study aimed to analyze conceptually how the application of PBL can enhance students’ comprehension in natural science learning at the elementary school level. A library research design was employed, drawing upon books, journal articles, and relevant prior studies, which were systematically reviewed and synthesized to examine theoretical foundations, practical implementations, and empirical findings of PBL in science education. The analysis revealed that PBL facilitates higher-order thinking skills by providing authentic problem contexts that require inquiry, collaboration, and reflective learning, thereby improving students’ conceptual mastery and their ability to connect scientific principles with real-life experiences. Furthermore, PBL was shown to strengthen creativity, motivation, communication, and collaboration among learners, making it an appropriate model to prepare students with competencies aligned to 21st-century education. The novelty of this study lies in its contextualization of PBL within Indonesian elementary education, highlighting both its theoretical potential and practical relevance for improving science literacy. The findings imply that educators, curriculum developers, and policymakers should consider integrating PBL as a strategic instructional model to enhance the quality of science teaching and learning, while future studies are encouraged to validate these insights through classroom-based empirical research.

Abstract

Improving the quality of science education in primary schools has become a central concern in Indonesia, where international assessments continue to indicate lower achievement levels compared to neighboring countries, thus underscoring the importance of adopting pedagogical approaches that foster inquiry and scientific reasoning from an early age. This study aimed to analyze the urgency of implementing the scientific approach in natural science learning at the elementary school level by situating it within the framework of the 2013 Curriculum. Employing a qualitative descriptive design, data were collected from policy documents, peer-reviewed journals, and scholarly books and analyzed through thematic analysis to identify key patterns, challenges, and opportunities related to the integration of inquiry-oriented instruction. The results reveal that while the scientific approach is conceptually aligned with international standards of inquiry-based learning and has the potential to enhance student engagement and critical thinking, its implementation in Indonesian classrooms remains constrained by systemic barriers such as limited teacher preparation, insufficient resources, and exam-driven teaching practices. The discussion highlights that bridging the gap between curricular policy and classroom practice requires sustained professional development, contextual adaptation of teaching strategies, and supportive educational policies that prioritize inquiry processes over rote memorization. This study contributes to the literature by offering novel insights into the conceptual and practical urgency of the scientific approach in developing country contexts and implies that successful integration could not only improve student learning outcomes but also strengthen the foundations of scientific literacy essential for twenty-first century competencies.

Abstract

The Covid-19 pandemic has rapidly transformed global education systems, pushing institutions toward online learning. This study explores the effectiveness of WhatsApp as an e-learning tool for the Biomolecules and Metabolism course in the Tadris IPA Program at IAIN Bengkulu during the pandemic. A mixed-methods approach, including a survey and semi-structured interviews, was employed to assess students' perceptions of WhatsApp's usability, its impact on engagement, and its effectiveness in facilitating learning. The findings show that WhatsApp was widely regarded as user-friendly, cost-effective, and accessible even in areas with weak internet connectivity. A majority of students (90%) reported that WhatsApp helped reduce data usage compared to other platforms, making it a more viable option for online learning. Moreover, WhatsApp’s group chat, document sharing, and audio message features significantly enhanced student engagement and participation. This study highlights the potential of WhatsApp as an alternative e-learning tool, particularly in resource-constrained environments. The novelty of this research lies in its focus on using WhatsApp in a specialized science course, contributing to the understanding of how mobile messaging platforms can support higher education in the post-pandemic era. The results suggest that WhatsApp can be a valuable tool for improving learning outcomes in science courses, though further research is needed to address challenges related to information overload and synchronous learning limitations.
Prevalence and Patterns of Pneumonia in Histopathology of Lungs from Qurban Cattle (Bos spp.) in Lampung, Indonesia (2019): A Laboratory-Based Survey Nursafitri, Umy; Sutyarso; Susanto, Gregorius Nurgroho; Widiastuti, Endang Linirin

Abstract

Pneumonia in cattle compromises welfare and carcass value, yet abattoir-based histopathology evidence from Indonesia’s qurban context remains scarce. To estimate the prevalence of pneumonia and characterize lesion patterns in lungs from qurban cattle processed in Lampung Province (2019). A cross-sectional, laboratory study analyzed 20 bovine lungs collected opportunistically from four districts (Bandar Lampung, Lampung Timur, Pringsewu, Metro). Representative tissues were fixed in 10% neutral buffered formalin, paraffin-embedded, sectioned at 4–5 µm, and stained with hematoxylin–eosin; bright-field microscopy (≈40×–400×) classified lesions a priori as interstitial pneumonia, bronchopneumonia, or aspiration-consistent pneumonia, and annotated severity (mild/moderate), temporality (acute/chronic), and distribution (focal/multifocal). Analyses were descriptive. 13/20 (65%) lungs met histological criteria for pneumonia, while 7/20 were normal. Interstitial cases showed alveolar-septal thickening, congestion/hemorrhage, and alveolar edema; bronchopneumonia was airway-centered with peribronchiolar cuffing and suppurative/fibrinosuppurative exudates; aspiration-consistent lesions exhibited focal/multifocal cranioventral involvement with foreign particulate material and neutrophilic exudates, occasionally with multinucleated giant cells. Most lesions were mild–moderate and predominantly acute. The profile indicates a multifactorial aetiology in which upstream infectious processes and perimortem handling both contribute, underscoring the added value of histopathology over gross inspection alone. Findings support immediate refinement of slaughter procedures (restraint, incision sequence, head positioning) to reduce aspiration risk; routine integration of histopathology paired with culture/PCR into abattoir surveillance for actionable supplier feedback; and periodic, micrograph-based auditing and training to strengthen food safety, animal welfare, and biosecurity.
