Abstract

Cohesion and coherence are pivotal aspects of academic writing. Although the analysis of these elements in academic texts has garnered considerable attention from researchers worldwide, there remains a notable paucity of studies focused on the research backgrounds of student texts, particularly with respect to their educational level. This study sought to explore how the effective utilization of Theme-Rheme structures can enhance the overall clarity and organization of students’ research backgrounds. Employing a qualitative content analysis approach inspired by Krippendorff (2004), this study meticulously scrutinizes fifty samples of academic papers to discern the prevalence and variations of Theme-Rheme patterns and their impact on the logical flow of information. The thematic structure formulated by Halliday & Matthiessen (2004/2014) and the thematic progression framework by Bloor & Bloor (2004) were instrumental in analyzing the data. The findings reveal that students utilize a variety of theme types in their research backgrounds. The unmarked theme is the most prevalent, accounting for 55% in undergraduate theses (UT), 54% in master's theses (MT), and 59% in doctoral dissertations (DD). Following this, the textual theme is utilized at rates of 30% in UT, 34% in MT, and 31% in DD. The marked theme appears less frequently, comprising about 13% in UT, 11% in MT, and 8% in DD, while the interpersonal theme is rarely employed, with an approximate usage of 2% across all educational levels. This study sheds light on the significance of Theme-Rheme structures in academic writing and offers valuable insights for educators and students alike, who are striving to enhance the quality of their academic papers.

Abstract

Despite the widespread adoption of Lean Manufacturing (LM), its effectiveness in the food industry remains underexplored, particularly regarding the integration of the Quality System (QS). The purpose of this research is to compare QS placement and LM implementation strategies in the food industry. This study utilized a comparative approach, analyzing empirical data from four food processing companies in Indonesia over six months, employing qualitative methods (expert interviews, document analysis) and quantitative analysis. Response Surface Methodology (RSM) with the Box-Behnken design was applied for optimization, while Principal Component Analysis (PCA) identified key variables influencing Lean Manufacturing success. Two implementation strategies were compared: phased implementation with a separate Quality System (Companies A and B) and simultaneous implementation with an integrated Quality System (Companies C and D). The findings revealed that Company A achieved the highest performance, with 88% in 5S and 85% in Just-In-Time (JIT), followed by Company B with 80% in JIT and 75% in 5S. In contrast, companies C and D exhibited lower performance. PCA results indicated that PC1 (80.40%) was associated with on-time delivery and sales growth, whereas PC2 (14.47%) was linked to rejection factors. Companies A and B excelled in PC1, while Companies C and D were more dominant in PC2. These findings suggest that phased implementation of LM tools is more effective than simultaneous application. This research not only addresses a critical gap in the literature but also provides practical insights for food industry practitioners seeking to enhance operational efficiency through Lean Manufacturing.
