Abstract

General Background Pesticide manufacturing plays a critical role in supporting agricultural productivity, yet complex production systems frequently generate operational waste and product defects. Specific Background PT XYZ produces multiple pesticide variants, with powder pesticides showing the highest defect proportion during the October 2024–September 2025 period, indicating inefficiencies within the production process. Knowledge Gap Despite recurring defects and extended lead time, systematic waste identification and structured failure risk prioritization had not been comprehensively applied in this production context. Aims This study aimed to identify dominant waste types, evaluate process performance, and formulate improvement recommendations using Lean Six Sigma integrated with Failure Mode and Effect Analysis. Results The analysis identified defects, waiting, transportation, and environmental health and safety as dominant wastes. Lead time was reduced from 763.11 minutes to 681.38 minutes through the elimination of non-value-added activities. Process performance showed an average DPMO of 37,519.68 with a sigma level of 3.28, alongside an increase in Process Cycle Efficiency from 59.55% to 66.69%. FMEA results indicated the highest Risk Priority Numbers were associated with non-standard product weight and product clumping caused by operator inconsistency and suboptimal machine performance. Novelty This study presents an integrated application of Lean Six Sigma and FMEA to map waste sources and prioritize failure risks within a pesticide powder production system. Implications The findings provide structured improvement recommendations, including operator training, standardized machine settings, and routine maintenance, offering a data-driven reference for manufacturing process optimization in similar industrial settings. Highlights: Defect-related losses constituted the largest proportion of inefficiencies in the studied manufacturing flow. Quantitative performance metrics demonstrated measurable reductions in processing time and defect opportunity rates. Risk prioritization revealed machine condition and operator consistency as dominant contributors to quality deviation. Keywords: Pesticides, Waste, Lean Six Sigma, FMEA

Abstract

Ecological thinking has increasingly emerged as a central paradigm in contemporary architectural theory, driven by escalating environmental degradation, climate change, and the growing recognition of complex interactions between the built environment and natural systems. Despite the expansion of green and sustainable architecture discourse, prior studies often remain fragmented, focusing separately on environmental performance, materials, or digital tools, without integrating ecological theory, architectural heritage, and technological innovation into a coherent framework. This study aims to systematically examine the evolution of ecological thinking in architectural theory and to clarify its role in shaping sustainable and adaptive design paradigms. The research adopts a qualitative methodology based on systematic literature review, historical–theoretical analysis, and comparative evaluation of architectural paradigms, drawing on peer-reviewed journal articles, theoretical monographs, and recent studies on sustainability, biomimicry, and digital design technologies indexed in major academic databases. The findings reveal a clear paradigm shift from mechanistic and form-oriented architectural models toward holistic, system-based, and interactive ecological approaches, in which architecture is understood as an adaptive component of broader environmental, cultural, and technological systems. The results also demonstrate that digital tools such as Building Information Modeling, data-driven design, and artificial intelligence increasingly support ecological thinking by enabling life-cycle analysis, adaptive responses, and integrative decision-making. The novelty of this study lies in synthesizing ecological theory, traditional architectural knowledge, and contemporary digital technologies into an integrated theoretical perspective, rather than treating them as isolated domains. The implications suggest that ecological thinking should be positioned not merely as an environmental strategy but as a foundational architectural paradigm, informing theory development, guiding sustainable design practice, influencing policy on the built environment, and reshaping architectural education toward interdisciplinary and ecologically grounded curricula.Keywords : Ecological Architectural Theory, Sustainable Design Paradigms, Systems-Based Design, Biomimetic Architecture, Digital Design TechnologiesHighlight : Ecological thinking redefines architecture as integrative systems linking environmental, cultural, technological, and social dimensions. Architectural paradigms shift empirically from mechanistic models toward holistic, adaptive, and system-based ecological frameworks. Digital technologies actively support resource-aware, responsive design, strengthening ecological integration across architectural practice.

Abstract

General Background: Elementary IPAS learning requires instructional approaches that foster active student engagement and meaningful understanding, yet classroom practices frequently remain teacher-centered. Specific Background: The use of audio visual learning media aligned with student characteristics has been identified as a strategic approach when supported by teacher creativity in instructional design and classroom implementation. Knowledge Gap: Despite extensive use of audio visual media in primary education, empirical examination of teacher creativity in utilizing such media and its statistical association with IPAS learning outcomes remains limited. Aims: This study aims to analyze the relationship between teacher creativity in audio visual media utilization and student learning outcomes in fourth-grade IPAS instruction. Results: A quasi-experimental one-group pretest–posttest design involving 30 students demonstrated a significant increase in mean scores from 54.50 to 83.37, with a moderate N-Gain value of 0.63. Paired sample t-test results indicated a statistically significant difference (p < 0.05). Correlation and linear regression analyses revealed a strong association (r = 0.783), with teacher creativity accounting for 61.3% of variance in learning outcomes. Novelty: This study provides empirical measurement of teacher creativity dimensions—critical thinking, alternative thinking, auditory, and visualization—in the context of audio visual media utilization in primary IPAS learning. Implications: The findings underline the importance of systematically developing teacher creativity in designing and managing audio visual learning media to support improved instructional quality in elementary IPAS education. Highlights • Significant score progression observed between pretest and posttest IPAS assessment• Teacher creativity dimensions show strong statistical association with student achievement• Visualization dimension demonstrates the highest contribution among creativity components Keywords Teacher Creativity; Audio Visual Learning Media; IPAS Learning Outcomes; Elementary Education; Quasi Experimental Study
