. This research is driven by the low literacy of plastic waste management in primary education, where students tend to perceive cleanliness only as disposing of trash without having the skills for reuse. This study aims to describe the utilization of recycled plastic waste media in enhancing students' environmental awareness at MI Salafiyah Syafi’iyah through an experiential learning approach. The method employed is descriptive-analytical qualitative, with data collection techniques including direct observation, interviews, and documentation. The research implementation was carried out through three main stages: participatory waste sorting, selection of clothing pattern designs as adhesive media, and the construction of creative collages into an educational display board named "Karyaku." The results indicate that the integration of plastic waste as a learning medium is capable of transforming students' paradigms from a consumptive to a creative perspective, as well as improving their practical understanding of the 3R principles (Reduce, Reuse, Recycle). The success of this research is evidenced by the creation of aesthetic and functional visual media that not only enhances students' creativity but also fosters a sense of responsibility and sustainable environmental concern for the school ecosystem.  

The assessment of students’ academic performance in higher education is generally still dominated by conventional numerical approaches, which are less capable of representing qualitative and subjective variables such as classroom activeness and student participation. These approaches often result in evaluations that are not holistic and do not fully reflect students’ overall academic achievements. Therefore, this study aims to analyze the concept of fuzzy logic as a support tool for assessing students’ academic performance in higher education, with a case study of students at Universitas Asahan. The research method employs a descriptive qualitative and quantitative approach by applying Mamdani fuzzy logic. The input variables consist of exam scores, assignment scores, and classroom activeness, while the system output is the category of academic performance, namely sufficient, good, and very good. The sample data consist of ten active undergraduate students from Universitas Asahan. The data processing stages include fuzzification, the construction of fuzzy rules (rule base), fuzzy inference, and defuzzification using the centroid method. The results indicate that fuzzy logic is able to integrate quantitative and qualitative variables and accommodate uncertainty in academic assessment. The resulting evaluation is more proportional and realistic compared to conventional assessment methods based solely on average scores. Therefore, fuzzy logic can be considered an effective and flexible alternative approach to support student academic performance assessment systems in higher education.

Criminal responsibility is constructed through the elements of homicide offences, the assessment of mens rea, accomplice liability, and sentencing rationality grounded in individual culpability. In judicial practice, however, cases involving the killing of women are frequently framed at the outset through the labels of “honour” or “intimate relationship,” leading honour killing and intimate partner femicide to be treated as interchangeable categories. This practice shifts the assessment of intent toward the perpetrator’s narrated motive and narrows accountability to the last physical actor. This research aims to formulate, first, legal criteria and evidentiary indicators for distinguishing the two categories through a staged judicial classification test, and second, to assess the implications of such classification for the construction of intent, the attribution of responsibility to non-executing actors, and sentencing rationality through disciplined reason-giving. The study employs a normative legal method with a conceptual approach, based on library research of primary and secondary legal materials. The findings demonstrate that the core deficiency lies in the absence of an operational classification device, allowing honour narratives to displace structured mens rea analysis and to obscure the causal contributions of non-executors. The article proposes working definitions and a stepwise indicator-based test—focusing on the presence of determinative social pressure or sanctioning, provable role allocation within perpetrator networks, and prior threats framed in terms of honour restoration—and links these indicators to concrete doctrinal consequences for intent, accomplice liability, and sentencing. Through this framework, judicial reasoning is redirected from label-driven interpretation toward accountability, while restraining the use of honour as a mitigating rationale and preventing femicide patterns from being concealed by reputational narratives.

Digital transformation in higher education has reshaped learning patterns and students’ academic practices, including how they manage and complete academic tasks. On the one hand, digital learning offers flexibility and easy access to learning resources; on the other hand, it has intensified tendencies toward academic task procrastination. This study aims to analyze students’ academic task procrastination as a socially constructed reality within the context of digital learning. The research adopts a qualitative approach with a case study design conducted at IAIN Fattahul Muluk Papua. Data were collected through in-depth interviews with students and lecturers and analyzed using Peter L. Berger and Thomas Luckmann’s social construction theory, encompassing the processes of externalization, objectivation, and internalization. The findings indicate that task procrastination is externalized through flexible learning schedules, digital media distractions, fatigue with instructional methods, and academic pressure. These practices are subsequently objectivated through students’ collective experiences and social relations with lecturers, leading them to be perceived as normative behavior in digital learning. Furthermore, task procrastination is internalized as a habit and an adaptive, taken-for-granted strategy within students’ learning rhythms. This study affirms that academic task procrastination cannot be reduced to an individual problem alone; rather, it emerges from the complex interaction between technological structures, pedagogical practices, and academic social dynamics. The findings are expected to contribute to the development of more reflective and contextual digital learning policies and strategies.

This study aims to analyze the effect of Tungsten Inert Gas (TIG) welding parameter variations on the mechanical and metallurgical properties of AISI 304 austenitic stainless steel, which is widely used in construction and industrial applications due to its excellent corrosion resistance and joint strength. The research focuses on identifying the optimal welding current to minimize welding defects and enhance joint structural integrity. Welding current was varied at three levels, namely 100 A, 125 A, and 135 A, while other parameters such as welding speed, argon shielding gas flow rate, and electrode type were kept constant. Mechanical properties were evaluated through Micro-Vickers hardness testing conducted in the weld metal, Heat Affected Zone (HAZ), and base metal, as well as tensile testing to determine ultimate tensile strength and elongation. In addition, non-destructive testing using the dye penetrant method was performed to detect surface welding discontinuities. Metallographic analysis was carried out using optical microscopy following an etching process to observe grain morphology, grain size, and the formation of microstructural phases. The results are expected to demonstrate a correlation between increased heat input due to higher welding current and changes in mechanical properties and microstructure, particularly in the HAZ. This study provides practical guidance for determining optimal TIG welding parameters for AISI 304 to achieve high tensile strength, homogeneous hardness distribution, and a stable microstructure resistant to intergranular corrosion.

The development of social media has made influencer parenting content one of the important sources of reference for the younger generation in understanding parenting. This study aims to examine the meaning of influencer parenting content for the younger generation in building future parenting. The research uses a qualitative approach with a literature review method on various scientific publications relevant to the topics of influencers, parenting, and digital media. The results of the study show that the younger generation interprets influencer parenting content not only as a source of practical information, but also as a reference for values and an ideal representation of the role of parents. The process of interpretation takes place actively and reflectively, influenced by personal experiences, family backgrounds, digital literacy levels, and socio-cultural contexts. In addition, the credibility of influencers and the style of delivering content also affect the acceptance rate of the audience. Influencer parenting content shapes a parenting discourse that emphasizes emotional awareness, empathic communication, positive parenting, and concern for children's mental health. Thus, the future parenting of the young generation is understood as a dynamic, adaptive, and constantly evolving social construction, with digital media as one of the main shaping factors.

Labor productivity is a critical factor in construction project success as it directly affects time, cost, and work quality. In the Palm Vista Residence housing development project, delays in ground floor structural works indicate suboptimal human resource performance. This study aims to analyze labor productivity levels, identify factors influencing productivity, and formulate strategies to improve productivity in sloof beams, columns, and floor slab works. The research employs a quantitative approach with descriptive-analytical methods through field observations, questionnaires, and interviews. Labor productivity is measured using the work sampling method and the Labour Utilization Rate (LUR), while influencing factors are analyzed using multiple linear regression. Strategy prioritization for productivity improvement is determined using the Analytical Hierarchy Process (AHP). The results show that labor productivity is at a moderate level and is significantly influenced by work experience, managerial aspects, and coordination and planning. The priority strategies include improving worker competence and strengthening project management practices. These findings are expected to provide practical guidance for construction labor management to enhance efficiency and ensure timely project completion.

The energy that is stored in water can be used to generate electricity by taking advantage of the potential energy available, like the energy from waterfalls and the movement of flowing water. Micro-hydropower plants (PLTMH) are one solution to address the energy crisis, particularly in electricity. VDI 2221 is a method that German engineers use as a guideline when designing construction projects. The VDI (Verein Deutsher Ingeneure or German Engineers Association) design process involves several stages: task description, design concept determination, physical design, and detailed design. Based on the solution principle matrix table, 3 variants were obtained, each of which has criteria. Of the 3 variants that have been evaluated, variant 2 was obtained with results that met the requirements. The cost analysis table shows that the total cost for designing a prototype test equipment for a micro-hydroelectric power plant (PLTMH) based on a laboratory-scale crossflow turbine is Rp 10,032,000. This cost includes instrumentation, control and electrical panels, measuring instruments, pipe instruments, frame and casing, and unforeseen costs.

Minister of Culture Fadli Zon's controversial statement, casting doubt on the existence of mass rape in the May 1998 Tragedy, sparked a strong public reaction, particularly from victims and human rights activists. This study aims to analyze Fadli Zon's statement as a form of identity politics in the context of contemporary Indonesian politics. This research uses a descriptive qualitative method with a discourse analysis approach to public statements, media coverage, and official documents such as reports from the National Commission on Violence Against Women and the Joint Fact-Finding Team (TGPF). The results show that Fadli Zon's statement is not merely a personal view, but rather a representation of identity politics that has the potential to obscure historical truth and reinforce social polarization. The identity politics that emerged in this discourse demonstrates how political power can influence the construction of national history and marginalize minority groups, particularly Chinese women victims of sexual violence. This study emphasizes the importance of historical honesty and the moral responsibility of political elites in preserving the nation's collective memory.

This article investigates the effectiveness of cooperative learning using vocabulary flashcards in improving students’ mastery of English adjectives. The research was conducted due to students’ limited vocabulary knowledge. The objective of this article was to examine whether the implementation of a cooperative learning model supported by vocabulary flashcards could enhance students’ adjective mastery and learning engagement. A pre-experimental research design with a one-group pretest–posttest approach was employed. The participants consisted of 15 junior high school students enrolled in an English course. Data were collected through pretest, posttest, classroom observation, and a student response questionnaire. Quantitative data were analyzed using descriptive statistics and N-Gain analysis, while qualitative data were obtained from observation sheets and questionnaire responses. The findings indicate a noticeable improvement in students’ posttest scores compared to their pretest results, with the mean N-Gain score categorized as moderately effective. In addition, observation data revealed high levels of student participation during cooperative learning activities. Questionnaire results further showed positive student responses toward the use of cooperative learning and vocabulary flashcards, particularly in terms of motivation, confidence, and ease of understanding English adjectives. These findings suggest that cooperative learning combined with vocabulary flashcards can effectively support students’ vocabulary development and active engagement. In conclusion, the study provides empirical evidence that cooperative learning facilitates meaningful interaction and knowledge construction, supporting its implementation in English vocabulary instruction. However, future research is recommended to involve larger samples and comparative research designs to strengthen the generalizability of the findings.

The development of the modern business world is marked by the increasing complexity of legal relationships between business actors, involving various entities with close economic and operational interconnections. This condition creates challenges in civil dispute resolution, especially when default occurs in multi-party business agreements. This study aims to analyze the application of the joint and several liability (tangung renteng) legal construction as a business dispute resolution mechanism in the Decision of the North Jakarta District Court Number 833/Pdt.G/2024/PN Jkt.Urr. This research uses normative legal research methods with statutory, conceptual, and case approaches. The legal materials used consist of primary legal materials in the form of legislation and court decisions, as well as secondary legal materials in the form of legal books and journals, which are analyzed descriptively-analytically. The results show that the panel of judges applied the joint and several liability construction not only based on formal contractual relationships, but also on the factual and economic interconnections between the parties, such as the receipt of benefits, operational integration, and the commingling of assets between the business entity and its management. The application of this construction proves effective in expanding the basis of liability and guaranteeing the recovery of creditor's rights. However, the decision also shows limitations in proving commercial immaterial losses, which are still bound by strict civil evidence standards. This study concludes that the joint and several liability construction can be an important instrument in resolving multi-party business disputes, but clearer jurisprudential guidelines are needed to ensure legal certainty and consistency of its application in the future.

The maritime transport sector plays a vital role in international logistics, including the transport of special cargo such as live cattle, which requires specific administrative and operational handling. PT. Bahari Eka Nusantara Belawan Branch, as a ship agency company, is responsible for ensuring the smooth flow of ship services from arrival to departure at the Port of Belawan. This study aims to analyze the flow of agency management for special cattle cargo on the vessel MV Gloucester Express and to identify the coordination efforts carried out with relevant agencies to ensure service efficiency. The method used in this research is descriptive qualitative with data collected through field observations and literature studies. The results show that the agency flow involves three main stages: pre-arrival, arrival, and departure, with a focus on strict animal health documentation and coordination with the Quarantine Office. The study concludes that while the process generally runs well, administrative precision and real-time communication with the authorities are critical factors in preventing delays in unloading live cattle.

This study critically examines the emerging phenomenon of celebrity preachers as a significant form of religious commodification within the realm of digital da’wah. The rapid proliferation of social media has fundamentally transformed how religious messages are disseminated, with platforms like YouTube, Instagram, and TikTok becoming primary channels. Utilizing a quantitative methodology that combines comprehensive literature studies with online questionnaires distributed to social media users, this research investigates public perceptions regarding digital da’wah practices and high-profile preachers. The findings reveal a commodification process characterized by three key aspects: the tailoring of content to suit market preferences, the shift of audiences into active consumers, and the strategic construction of public images by preachers to sustain popularity. While respondents value the accessibility of digital da’wah, they strongly emphasize the necessity of ethical boundaries to preserve its spiritual essence. Consequently, digital da’wah requires sincerity, scholarly integrity, and moral responsibility to remain an authentic medium for Islamic teachings.

This article examines the role of context and underlying assumptions in the formulation of econometric models for economic policy analysis. While econometric models are widely employed to support policy decisions, their construction is often treated as a purely technical process, overlooking the contextual factors that shape variable selection, model specification, and interpretation of results. This study explores how institutional settings, policy objectives, and behavioral considerations influence the assumptions embedded in econometric modeling. By drawing on policy documents, academic literature, and illustrative cases from applied economic research, the article highlights how implicit assumptions may affect the validity and relevance of econometric outcomes. The analysis emphasizes that econometric models are not value-neutral tools but are shaped by theoretical choices and contextual judgments made during their formulation. Understanding these dimensions is crucial to avoid misinterpretation of empirical findings and to enhance the usefulness of econometric analysis in policymaking. The study contributes to the methodological discussion in applied econometrics by encouraging greater transparency and reflexivity in model construction, particularly in the context of economic policy evaluation.      

PT Adhi Karya (Persero) Tbk is a State-Owned Enterprise (BUMN) in Indonesia that operates in the construction industry. PT. Adhi Karya (Persero) Tbk. was awarded the contract for the Yogyakarta-Bawen toll road construction project, Package 1, Section 1. Construction safety is a very important aspect in the project. The toll road construction project involves work at heights, especially on erection grider work. Erection grider work is a high-risk job, so construction safety must be guaranteed. If construction safety is not guaranteed in the work environment, workers will be more careful in working to reduce risks so that work slows down. This can reduce work productivity. However, when safety is guaranteed, workers will feel safe to work so that it can increase work productivity. This study aims to determine the effect of construction safety (X) on work productivity (Y). The data collection method was carried out by distributing questionnaires to 30 respondents of erection grider workers. Data processing used the Structural Equation Modeling–Partial Least Squares (SEM PLS) method with SmartPLS 4.0 software. The results of data processing showed that construction safety had a significant influence on work productivity with a t-statistic value of 7.329 and a p-value of 0.000.  

Electronics learning in higher education continues to face various challenges, particularly in the provision of interactive learning media capable of concretely and engagingly visualizing the form, characteristics, and working principles of electronic components. The limitations of conventional learning media often result in abstract learning processes, which in turn lead to a low level of student understanding of basic electronics concepts. This study aims to develop the AMPERE as an innovative and technologically relevant interactive learning medium. The research employed R&D approach using the Borg & Gall model, which includes the stages of needs analysis, design, product development, validity testing, and limited implementation. The AMPERE application was developed using marker based AR technology, in which a smartphone camera detects markers to display and interact with 3D electronic component objects in real time. The results indicate that the AMPERE application achieved a high level of validity, with a score of 0.88 from subject-matter experts and 0.84 from media experts, and was therefore deemed suitable for use as a learning medium. The small-group trial results showed a practicality level of 82.07%, while the practicality test during the implementation stage reached 85.67%. These findings demonstrate that AMPERE is effective in enhancing learning interactivity and assisting students in understanding the form, function, and working principles of electronic components through smartphone-based digital visualization. Theoretically, these results are consistent with constructivist learning theory, which emphasizes active knowledge construction through direct experience and interaction with learning objects.

Autonomous decision-making systems increasingly rely on complex artificial intelligence models to operate in dynamic and safety-critical environments. While these models provide strong predictive capabilities, their black-box nature limits transparency, trust, and accountability. This study proposes a structured research methodology for integrating Explainable Artificial Intelligence (XAI) into autonomous decision-making systems. The research adopts a conceptual–analytical approach to develop an explainability-oriented framework that embeds transparency across perception, decision-making, and action execution stages. The methodology includes literature-driven problem identification, conceptual framework construction, classification and mapping of XAI methods, and formulation of explainability evaluation criteria. The results demonstrate that effective explainability in autonomous systems requires a hybrid integration strategy, combining in-model transparency with post-hoc explanation mechanisms. A structured mapping of XAI techniques to autonomous system components and a conceptual decision-flow diagram are presented to illustrate explainability integration. The findings highlight that layered and context-aware explainability enhances system interpretability, supports human oversight, and improves safety relevance without compromising autonomous operation. This study contributes a reusable methodological foundation for the design and evaluation of explainable autonomous systems, offering practical guidance for future empirical validation and real-world deployment in safety-critical applications.

Semantic interoperability remains a major challenge in large scale distributed information systems due to heterogeneous data schemas, diverse contextual interpretations, and the dynamic nature of distributed environments. Traditional metadata-based interoperability approaches are often insufficient to address these challenges, as they lack semantic expressiveness and adaptability. This study proposes a context aware knowledge graph framework to enhance semantic interoperability across heterogeneous distributed systems. The research adopts a design-oriented methodology involving requirement analysis, knowledge graph construction, ontology modeling and alignment, context aware semantic representation, and semantic reasoning. A prototype implementation is developed to evaluate the effectiveness of the proposed framework through interoperability scenarios and cross-system semantic queries. The results demonstrate that the proposed approach significantly improves semantic alignment accuracy, query precision, and recall compared to conventional metadata-based solutions. The explicit integration of contextual information and ontology-based reasoning enables adaptive semantic interpretation and reduces ambiguity across systems. Overall, the findings confirm that combining knowledge graphs with ontology modeling and context aware mechanisms provides a robust and scalable solution for improving semantic interoperability in complex distributed information systems.

Corporate crime in the natural resources sector is a legal phenomenon that has a broad impact on state finances and public interests. This article analyzes the legal case of tin trade corruption involving PT Timah Tbk, a state-owned enterprise managing a strategic commodity. This study aims to examine the construction of corporate crime and the legal implications of state financial losses arising from deviant trade practices. The research method used is normative legal research with a juridical-analytical approach through a review of laws and regulations, legal doctrine, and relevant legal facts. The results of the study indicate that tin trade corruption is a systemic corporate crime integrated into the company's policies and business mechanisms, so that criminal liability cannot be limited to individuals alone. The resulting state losses are multidimensional, including fiscal losses, loss of potential revenue, and violations of the principle of state control over natural resources. This study emphasizes the importance of strengthening corporate criminal law enforcement to maintain the integrity of state-owned enterprises and protect state interests.
