Abstract

The cement industry is an important sector in infrastructure development, where the quality of clinker determines the final quality of the product. This study evaluates the application of T² Hotelling's and Generalized Variance (GV) multivariate control charts to clinker data based on three main variables: FCaO, C₃S, and C₃A at PT XYZ. The results show that C₃S has the highest variance in phase I and II (2.61 and 2.53), while FCaO has the lowest variance (0.10 and 0.06). All three variables had mean values within the specification limits, although there were still extreme values outside the limits. Assumption tests showed that the data was not multivariate normally distributed, but it was still assumed to be normal for control analysis purposes. In the wet season, the standard deviation decreased from 1.552 to 1.252, and in the dry season from 1.170 to 1.029, indicating a decrease in variability although the process is not yet fully under statistical control. Capability analysis shows that the dry season process is more stable, with most parameters having multivariate values that exceed the threshold. Compared to the wet season, the dry season process showed more consistent performance and was able to meet production quality standards.

Abstract

Partial Least Squares is increasingly used as an alternative to covariance-based SEM due to its flexibility in handling non-normal data, small sample sizes, and complex models, as well as its ability to operate under different inner weighting schemes. However, empirical studies rarely compare these weighting schemes, even though they may influence measurement validity and structural interpretations. This study applies PLS-SEM using both the path and factor weighting schemes to evaluate their performance in modeling child malnutrition. Child malnutrition remains a major public health concern, as it is driven by the interaction of socioeconomic, food security, parenting, and access to basic services. The study estimates and evaluates measurement and structural models using PLS under path and factor schemes. The findings show that both schemes produce acceptable measurement and structural models, but the path scheme yields more consistent indicator significance and more stable structural relationships, while the factor scheme is more sensitive to weaker indicators, leading to some nonsignificant loadings and paths. The results suggest that although both weighting schemes are suitable for exploratory analysis, the path weighting scheme provides more robust and interpretable results for explaining child malnutrition, highlighting the importance of weighting scheme selection in applied PLS-SEM research.

Abstract

The students’ low ability on mathematical literacy caused by teachers’ monotonous learning process and lack of students’ participation in teaching and learning process. This research aims to determine if Missouri Mathematics Project (MMP) is able to improve students’ mathematical literacy ability more effectively than direct learning model. In addition, the researcher explores how gender affects the effectiveness of MMP. The gender contribution here is what the differences of male and female students’ mathematical literacy ability are. The approach used in this research is quantitative research and the method is quasi-experimental having design of non-equivalent controlled group design. There are 70 students of grade X as sample consisting 35 students in experimental classes and 35 students in controlled classes (simple random sampling technique). The data taken in this research through mathematical literacy written test as the instrument and documentation. The analysis technique used is a two-way analysis of variance. The research results shows that students who are taught using the MMP model have significant effect on mathematical literacy ability than the students who are taught using direct learning.  Female students’ mathematical literacy ability is better than the male students’ ability. There is a correlation between learning model and gender differences on mathematical literacy ability. Both male and female students’ mathematical literacy ability who are taught using MMP learning model is higher than male and female students’ ability who are taught using direct learning model Thus, MMP can be implemented as an alternative learning model to develop students' mathematical literacy ability. Kurangnya kemampuan literasi matematis dikarenakan oleh proses pembelajaran yang lebih monoton pada guru serta minimnya keaktifan siswa dalam proses pembelajaran. Studi ini untuk mengetahui apakah MMP (Missouri Mathematics Project) lebih efektif dalam mengembangkan literasi matematis daripada pembelajaran langsung. Selain itu, akan diekplorasi bagaimana gender mempengaruhi efektifitas MMP. Kontribusi gender yang dimaksud yaitu bagaimana perbedaan kemampuan literasi matematis antara laki-laki dan perempuan. Metode penelitian yang digunakan adalah kuantitatif dengan desain quaisy experimental. Sebanyak 70 siswa kelas X yang dijadikan sebagai sampel yang terdiri dari 35 kelas eksperimen dan 35 kelas kontrol (teknik simple random sampling). Instrumen penelitian dilakukan melalui tes literasi matematis, dan dokumentasi. Teknik analisis data menggunakan analisis varians dua jalur. Penelitian tersebut menemukan bahwa siswa yang diajar dengan model pembelajaran MMP memiliki literasi matematis lebih baik dibandingkan siswa yang diajarkan menggunakan pembelajaran langsung. Kemampuan literasi matematis siswa perempuan lebih tinggi daripada laki-laki. Terdapat interaksi antara MMP dengan perbedaan gender terhadap kemampuan literasi matematis. Kemampuan literasi matematis siswa laki-laki yang menerapkan MMP lebih tinggi dibandingkan dengan yang menerapkan pembelajaran langsung. Kemampuan literasi matematika siswa perempuan dengan menerapkan MMP lebih tinggi dibandingkan kemampuan siswa yang menerapkan pembelajaran langsung. Sehingga, MMP dapat dijadikan alternatif model pembelajaran untuk mengembangkan kemampuan literasi matematis siswa.
