Abstract

Students’ success in learning mathematics can be measured from the learning process. By learning mathematics, it is expected that students can improve their thinking ability that includes the ability to reason, solve problems, communicate, and respect the usefulness of Mathematics. However, preliminary observation had showed that students’ achievement in learning mathematics is relatively low due to conventional methods of instruction. This research aims at; 1) finding out the students' responses to the application of thematically integrated learning in Mathematics, 2) finding out students’ reasoning skills in the composition of the two functions and inverse functions, and 3) finding out the effect of thematically integrated instruction in Mathematics on students’ reasoning ability. It is expected that the implementation of this learning model would improve students’ Mathematic achievement. The results demonstrate a regression equation of Y = 15.477 + 0,714X, a regression coefficient is positive of 0.714. This can be interpreted as a response to the implementation of thematic learning model thet the better it will improve students’ reasoning ability. Number R Square of 0,151. Meaning that the level of reasoning ability of students’ affected by the high and low stundents’ response to the implementation of thematic learning model 15,1%. The implementation of thematic learning model in the study of mathematics can be see from the results of the regression coefficient test showed thet significant value 0,007 < 0,05. Therefore, Ho is rejected. This result illustrates that there is a significant effect of the implementation of thematic learning model in teaching mathematics on students' reasoning ability.Keywords: Thematically Integrated Instruction, Ability, Reasoning

Abstract

As the international community pays more and more attention to environmental issues, people tend to think about how to adapt to various issues in order to progress and develop in an environmentally conscious way in this era of globalization. The increasing demand for innovative and environmentally friendly products has prompted companies to focus on creating green supply chains, and companies adopt practices that minimize environmental damage (Rehman et al., 2015), which makes this a necessary condition to address competition in global markets Businesses innovate, select companies that meet the green supply chain standards for evaluation. This research aims to get the right criteria when selecting green kaolin suppliers in the supply chain and prioritise suppliers to find out which one is the best fit for the company.Method used in this study is the BWM method for weighting criteria and assessing the performance of green supply chain-based kaolin suppliers using the PROMETHEE method. This study compares the TOPSIS and Promethee methods in their ranking and the results show that the Promethee method has accuracy and correlation with ranking values ​​ (Beniyanto & P, 2018), and can be used for qualitative and quantitative data compared to TOPSIS, but TOPSIS has the advantage that the concept is simpler and easier understood so that decision-making is faster.
