INTRODUCTION Effective management of time and cost is universally acknowledged as a cornerstone of successful construction project delivery. In the field of civil infrastructure development, projects are typically constrained by limited resources, demanding strict adherence to schedule and cost frameworks to ensure optimal outcomes (Kerzner, 2. From an ideal perspective, construction management techniques such as Critical Path Method (CPM). Program Evaluation and Review Technique (PERT), https://jurnaledukasia. EDUKASIA: Jurnal Pendidikan dan Pembelajaran. Vol. 7, 1 (January-June, 2. 334 of 344 Earned Value Management (EVM), and other integrated scheduling tools are designed to provide systematic frameworks for planning, monitoring, controlling, and adjusting project performance across the life cycle (PMI, 2. When applied rigorously, these methods enable early identification of variances, facilitate corrective actions, and contribute to predictable delivery within budget and timeline commitments (Project Management Institute, 2. In theory, the integration of these techniques should yield measurable improvements in schedule adherence and cost control outcomes that are critical for infrastructure projects including river embankments, flood control systems, and other water-related developments. Despite these theoretical underpinnings, empirical observations from recent studies reveal persistent challenges in achieving ideal time and cost performance outcomes across construction For instance, evaluations of large dam construction projects using Earned Value Analysis have frequently shown schedule delays and cost overruns, with Schedule Performance Indices (SPI) and Cost Performance Indices (CPI) deviating significantly from planned values (Musyarofah et al. , 2. Similarly, projects combining structural reinforcement with complex hydrological requirements often encounter unforeseen obstacles such as delayed material deliveries, limited labor productivity, and logistic constraints factors that contribute to extended project durations and higher expenditures (Musyarofah et al. , 2. In flood control infrastructure specifically, delays in land acquisition and preparatory works have been empirically linked to deteriorated time and cost performance, indicating that site-specific socio-economic factors remain critical determinants of outcomes (Topan et al. , 2. The application of construction management techniques in river embankment and flood control projects has been underscored in studies focusing on hydraulic infrastructure. For example, analyses of flood control and embankment reinforcement works show that risks associated with weather conditions, addendum costs, and changes to field conditions significantly affect both time and cost performance metrics (Yuliana & Rani, 2. Some projects have adopted CPM and EVM methods to measure variances and forecast final cost and duration, yet these evaluations often highlight suboptimal performance, with corrective measures applied only reactively rather than proactively (Salsabila et al. , 2. Such findings suggest that even though construction management techniques are being utilized, their effectiveness in ensuring schedule and budget compliance varies widely across project types and contexts. This observation raises critical questions about the appropriateness of existing application models and the extent to which they address the unique operational dynamics of river embankment development projects. River embankment projects in particular present a unique set of complexities that differentiate them from conventional building construction or transportation infrastructure works. Unlike standard horizontal construction projects, river embankment developments must respond to hydrologic variability, environmental permitting requirements, soil mechanics challenges, and potential flood incidents during execution. These factors impose dynamic risks and interdependent constraints that complicate time and cost performance predictability. However, despite these complexities, the construction management literature has traditionally focused on generalized project environments, with limited research dedicated specifically to river embankment scenarios (Syah Putra et al. , 2. Moreover, current empirical studies that do engage with such hydraulic projects often emphasize descriptive performance assessments without offering rigorous comparative evaluations of alternative management techniques or adaptive solutions that could mitigate observed inefficiencies. The research gap becomes particularly evident when considering the lack of comprehensive analytical research that critically compares the efficacy of different construction management techniques . CPM vs. EVM vs. hybrid approache. within the specific context of river embankment While prior studies have documented variances in SPI and CPI values, few have interrogated the underlying causal mechanisms such as risk management integration, real-time Ramadhana Agung Pratama.

Vol. 7, 1 (January-June, 2. 335 of 344 monitoring, stakeholder communication flows, and adaptive decision frameworksAithat determine why some techniques perform better than others in complex infrastructural settings. Additionally, there is limited evidence on how predictive scheduling models and cost forecasting tools can be effectively customized for embankment projects, which often involve cyclical environmental constraints and multi-phase construction sequencing. Consequently, existing literature exchanges descriptive findings for prescriptive insights, leaving practitioners with ambiguous guidance on optimal management strategies tailored to these project types. Given this backdrop, it is necessary to formulate specific queries that can guide a focused investigation into time and cost performance under varying construction management paradigms. Therefore, this study seeks to address the following core questions: . How do different construction management techniques influence schedule adherence and budget control in river embankment projects, as measured by standard performance indices such as SPI and CPI? . To what extent do integrated risk management practices and real-time performance tracking contribute to improved outcomes in embankment development contexts? Operationally, this research will quantify time and cost variances against planned baselines using recognized performance metrics, and compare the relative effectiveness of selected techniques in moderating those variances throughout project The primary objective of this study is to evaluate time and cost performance in river embankment development projects through the application of various construction management techniques, and to determine which approaches yield superior performance results when faced with typical execution Secondary objectives include identifying key risk factors that influence project outcomes and proposing methodological adaptations to enhance management practices. By doing so, this research aims to generate actionable insights for project managers, policymakers, and industry stakeholders engaged in hydraulic infrastructure implementation. METHODS Design This study employed a Research and Development (R&D) design integrated with a quasiexperimental approach. The R&D design was selected because the primary objective of the study was to develop an Android-based learning media for Islamic Cultural History and subsequently evaluate its effectiveness in improving studentsAo learning outcomes.

Student response analysis demonstrates a strong level of acceptance and perceived usefulness. Learners reported that the Android-based media facilitated independent learning, increased attention during instructional activities, and reduced cognitive overload commonly experienced in text-dominated history lessons. Importantly, students perceived the integration of multimedia elements such as images, animations, and interactive quizzes as enhancing comprehension rather than serving as mere visual This finding is critical because it indicates that the media functioned as a cognitive support tool rather than a distraction, reinforcing its pedagogical practicality in real classroom The effectiveness of the Android-based learning media was further examined through comparative analysis of studentsAo learning outcomes before and after its implementation. Statistical analysis of pretest and posttest scores reveals a substantial improvement in studentsAo cognitive The post-intervention scores were consistently higher than pre-intervention scores, indicating that students demonstrated stronger mastery of historical concepts, chronological reasoning, and contextual understanding after engaging with the media. The normalized gain (N-gai. analysis places this improvement in the medium-to-high effectiveness category, suggesting that the learning gains were not incidental but systematically attributable to the instructional intervention. This improvement reflects the mediaAos capacity to transform abstract historical narratives into concrete and meaningful learning experiences. During the implementation phase, student responses revealed that usability and pedagogical design play a decisive role in determining whether digital media can be meaningfully adopted in classroom practice. The positive student perceptions indicate that the media functioned not merely as a technological novelty, but as a genuine learning support tool. This reinforces the importance of practicality and learner acceptance as key indicators of instructional feasibility in educational technology research. From a critical perspective, the observed learning gains can be interpreted as evidence of improved cognitive processing facilitated by multimedia learning principles embedded in the Android-based The structured sequencing of content, combined with interactive reinforcement through quizzes, appears to have supported both knowledge retention and conceptual transfer. Unlike conventional lecture-based instruction, which often positions students as passive recipients of information, the developed media promoted active engagement by allowing learners to control pacing, revisit materials, and immediately test their understanding. This shift in learning dynamics is significant, as it aligns with constructivist learning theory, where learners actively construct meaning through interaction with learning resources. Moreover, the results suggest that the effectiveness of the media is closely linked to its contextual The integration of Islamic Cultural History content within a digital platform familiar to studentsAo daily technology use enhanced motivational aspects of learning. Rather than perceiving history as a static and memorization-heavy subject, students engaged with it as an interactive and exploratory experience. This finding challenges the assumption that learning difficulties in historical subjects are primarily content-related. instead, it underscores the role of instructional media design in shaping studentsAo learning outcomes.
