Abstract

Science learning at the MTs level still often faces the problem of low student learning outcomes because the learning process tends to take place conventionally, is less interactive, and has not fully encouraged active student involvement. This condition is also found in grade VIII students of MTs Darul Ulum, where most of the students have not reached the completion of learning in science subjects. This study aims to analyze the application of quartet card media in improving the science learning outcomes of grade VIII MTs Darul Ulum students, describe the application process, and identify students' responses to the use of the media. The research uses the Classroom Action Research approach which is carried out in two cycles, with stages of planning, action implementation, observation, and reflection. The research subjects amounted to 22 students in grade VIII. The research instruments included learning outcome tests, observation sheets, structured interviews, and documentation. The results showed that student learning completeness increased from 18 percent in pre-action to 40 percent in cycle I and 86 percent in cycle II. In addition, students show a positive response in the form of increased enthusiasm, cooperation, and activeness during learning. Thus, quartet card media has proven to be effective in improving science learning outcomes while improving the quality of the learning process in a more active, fun, and meaningful way

Abstract

This research is motivated by the low learning activity of students in science learning at MTs Darul Hikam which is shown by the dominance of the use of conventional methods centered on teachers, so that students are less involved in asking questions, discussing, answering questions, and expressing opinions. This research aims to increase student learning activity through the application of the Jigsaw-type Cooperative Learning model in science learning. The method used is Classroom Action Research with a two-cycle design, and each cycle includes the stages of planning, implementation of actions, observation, and reflection. The subjects of the study were 25 students of class VIII C MTs Darul Hikam, while the data were collected through observation, interviews, documentation, and questionnaires, then analyzed qualitatively and quantitatively. The results showed that students' learning activity gradually increased from 38.83 percent in the first cycle of the first meeting to 54.67 percent in the second meeting, then increased again to 80.3 percent in the second cycle of the first meeting, and reached 91.83 percent in the second meeting. In conclusion, the application of the Jigsaw model is effective in increasing students' learning activity in science learning. The novelty of this research lies in the focus on measuring multidimensional learning activity in the context of madrasah tsanawiyah, while the implications show that the Jigsaw model is feasible to be applied as an innovative strategy to create more participatory, collaborative, and meaningful science learning

Abstract

This study aims to examine the economic and environmental determinants of coconut farmers’ income in Simeulue Regency by analysing land area, selling price, labour, and damaged trees as independent variables, with farmers’ income as the dependent variable. This study employs a quantitative method based on multiple linear regression analysis of primary data collected through questionnaires and interviews with 97 coconut farmers selected using the Slovin formula, supplemented by secondary data from relevant institutions. The results indicate that all variables simultaneously influence farmers’ income; however, when analysed individually, land area and labour have a positive and significant effect, the selling price shows a positive effect, and damaged trees have a negative but non-significant impact on income levels. These findings imply that owning larger landholdings and utilising labour efficiently can help increase farmers’ income, whereas pest-damaged trees remain a major challenge for boosting productivity. Therefore, efforts such as improving land management, optimising labour use, maintaining price stability, and implementing sustainable pest control are crucial for improving the welfare of coconut farmers in Simeulue Regency.

Abstract

The reliability of electric vehicle charging connectors depends on correct seal installation, since the seal protects the interface from dust and moisture. This study developed an IoT-enabled cyber-physical assembly system integrating fiber-optic and photoelectric sensors, a programmable logic controller, pneumatic actuation, a Raspberry Pi edge gateway, and a human-machine interface. The system was evaluated on an industrial production line using the same connector model, machine, operating procedure, and inspection criteria as the baseline. The baseline rejection rate, drawn from routine production records before implementation, was 19.18%. After calibration, 600 consecutive connectors were assembled during a continuous five-hour validation run, with manual inspection by experienced quality personnel serving as the reference standard. The post-implementation rejection rate fell to 2.80%, an 85.41% relative reduction (16.38 percentage points), yielding a production yield of 97.17%. The detection system achieved 99.50% accuracy, 88.89% precision, 94.12% recall, 99.66% specificity, and a 91.43% F1-score. Average cycle time was 30 seconds per unit, with a repeatability error of ±0.10 mm across 30 repeated press-depth measurements. These results indicate improved defect prevention, assembly consistency, and traceability under the evaluated conditions, with remaining defects mostly outside the seal-sensing scope.

Abstract

Student engagement is a crucial factor in academic success, as it reflects students’ behavioral, emotional, and cognitive involvement in the learning process. However, academic demands often lead to stress, anxiety, and burnout, which may reduce students’ engagement. One psychological factor that has the potential to enhance student engagement is self-compassion, defined as the ability to treat oneself with kindness, recognize failure as part of the shared human experience, and maintain balanced awareness of personal difficulties. This study aims to systematically review the role of self-compassion in student engagement among university students. A Systematic Literature Review (SLR) approach was employed following the PRISMA 2020 guidelines. Data were collected from the Scopus and Taylor & Francis databases using the keywords “self-compassion,” “student engagement,” and “higher education.” Of the 46 articles initially identified, 18 met the inclusion criteria and were included in the analysis. The findings indicate that self-compassion positively contributes to psychological well-being, emotion regulation, resilience, and academic motivation while reducing burnout, anxiety, and fear of failure. Furthermore, self-compassion was found to function as both a mediator and a moderator in the relationship between various psychological factors and student engagement. These findings suggest that self-compassion serves as an important psychological resource that supports students’ academic involvement. Therefore, integrating self-compassion development into counseling services, character-building programs, and technology-based interventions may represent an effective strategy for enhancing student engagement in higher education.

Abstract

Artificial intelligence (AI) has played a crucial role in improving the efficiency and accuracy of financial data management in the accounting field through process automation, big data analysis, and faster and more precise decision-making. This research aims to analyze the perception of accounting students in Indonesia towards the application of artificial intelligence (AI) in the digital transformation of accounting. Using a descriptive quantitative method with a survey of 163 respondents, the results showed that the majority of students understood that AI has been applied in companies and got information from the internet and social media. They agree that AI can automate routine tasks, increase efficiency, and minimize errors in the accounting process. However, the study also revealed concerns regarding potential workforce reductions, over-reliance on technology, and data security risks and skills gaps that could exacerbate social inequality. These findings highlight the importance of improving student competencies and attention to social, ethical, and security aspects in the application of AI so that its benefits can be utilized optimally and responsibly in the digital era.

Abstract

This study formulates a container rental development strategy for subcontractors operating in state-owned shipyards in Surabaya. A mixed-method design was applied through tenant questionnaires, interviews with internal managers, expert judgement, and document review. The strategic formulation process integrated the IFE, EFE, IE, SWOT, BCG, and QSPM matrices in sequential stages: identifying internal and external factors, determining the business position, generating alternative strategies, comparing business-unit portfolios, and prioritizing the most attractive strategy. The IFE score of 2.84 indicates that the company has a moderate-to-strong internal position, while the EFE score of 2.70 shows a moderate response to external opportunities and threats. The IE Matrix places the company in Cell V, suggesting a Hold and Maintain orientation. SWOT analysis generated market penetration and product development as the most relevant alternatives, while BCG analysis indicated a declining portfolio condition that requires more active market action. The QSPM result shows that market penetration obtained the highest Total Attractiveness Score of 5.07, compared with 4.72 for product development. Therefore, market penetration is recommended through digital promotion, responsive customer service, simplified rental procedures, and customer expansion.

Abstract

Dissimilar steel joints are increasingly employed in demanding engineering structures, yet repeated thermal cycles during multi-pass welding can generate complex microstructural heterogeneity and localized mechanical-property gradients that affect structural integrity. This study investigates the relationship between cumulative welding thermal history, microstructural evolution, local property variation, and tensile fracture behavior in multi-pass dissimilar steel joints. An experimental laboratory design integrated controlled multi-pass welding, metallographic characterization, microhardness mapping, transverse tensile testing, fracture-location analysis, and fractographic examination to establish process–structure–property relationships. The results revealed pronounced microstructural and hardness variations across the weld metal, fusion boundaries, heat-affected zones, and base materials due to unequal thermal histories and repeated reheating. Tensile fracture occurred preferentially within or adjacent to mechanically heterogeneous transition regions rather than consistently within the weld centerline or maximum-hardness zone, demonstrating the critical influence of local strength–ductility mismatch and deformation compatibility. The study concludes that tensile performance cannot be adequately explained by average strength or peak hardness alone. An integrated pathway linking thermal history, microstructural evolution, property gradients, strain localization, and fracture behavior provides a stronger mechanistic framework for evaluating joint integrity and optimizing multi-pass welding procedures for reliable dissimilar steel structures under demanding industrial service conditions.

Abstract

Water-quality deterioration requires timely and reliable monitoring, yet conventional laboratory-based approaches often face limitations in cost, sampling frequency, spatial coverage, and response time, particularly in resource-constrained environments. This study aimed to design, calibrate, and validate a low-cost Internet of Things sensor instrumentation system for continuous real-time water-quality monitoring. An experimental engineering design integrated multi-parameter sensing, embedded processing, wireless communication, laboratory calibration, reference-based comparison, field validation, data-transmission assessment, and threshold-based alert evaluation. The results demonstrated strong calibration performance across monitored parameters, although field accuracy varied according to sensor type and environmental conditions. Temperature and pH exhibited comparatively stable performance, whereas turbidity and dissolved oxygen showed greater field-related measurement variability. The system maintained high data completeness and communication reliability while successfully capturing short-duration water-quality changes that periodic sampling could potentially miss. Field validation confirmed that strong laboratory calibration alone did not guarantee equivalent performance under natural environmental conditions. The study concludes that low-cost IoT instrumentation provides a promising fit-for-purpose platform for continuous surveillance, temporal pattern detection, and early warning when supported by rigorous calibration and field validation. The proposed end-to-end framework strengthens the development of scalable, reliable, and context-sensitive water-quality monitoring systems for environmental management.

Abstract

Floating-house settlements (rumah lanting) in Kampung Awang Landas remain an adaptive form of water-based housing but face physical deterioration, limited basic services, and weak policy recognition. This study examined the physical transformation of rumah lanting and identified management priorities using a sequential exploratory mixed-methods design. Qualitative exploration involved 15 informants, comprising 12 floating-house residents, two government officials, and one community elder. The subsequent assessment covered all 18 floating-house units and used Analytic Hierarchy Process (AHP) judgments from three purposively selected experts. Qualitative and observational findings were used to formulate four AHP criteria and 16 subcriteria. The results showed that 50.0% of units were in moderate condition and 27.8% were in poor condition, with the most extensive material transformation occurring in roofs and walls. AHP synthesis ranked Institutional and Government Policy as the highest-priority criterion (0.378), followed by Technical-Infrastructure (0.293), Economic-Livelihood (0.206), and Socio-Cultural and Local Wisdom (0.123). The highest-ranked subcriteria were Policy Direction (0.146), Floating-House Legality and Land Tenure Status (0.112), and Basic Utilities (0.098). The study proposes the PPAI framework, comprising Policy, Physical, Access, and Institutional dimensions, as an evidence-informed planning framework for context-sensitive floating-house settlement management in Kampung Awang Landas.
