The Cost

This work describes a strategy to reduce the cost associated with poor quality, by reducing the parts per million defects by Defining, Measuring, Analyzing, Implementing and Controlling (DMAIC) the production process. The method uses a combination of principles of Six Sigma applications, Lean Manufacturing and Shanin Strategy. The process has been used in analyzing the manufacturing lines of a brake lever at a Connecticut automotive components manufacturing company for reducing the cost associated with the production of nonconforming parts. The analysis was carried out with the help of the data collected on nonconformance parts and the application of phase change rules from DMAIC (+). Data analysis was carried out on statistical process control softwares, MINITAB and SPC XL 2000. Although, the problem of tight bushing existed on only one line of the brake lever assembly, this problem solving approach has solved the tight bushing problems on all assembly and alternates lines in a time- and cost-effective way.

Solving Strategy

This study was an Action Research which was conducted because the student’s achievement on Mathematics  were still lower than The Minimum Achievement Criteria (KKM). The research was conducted to see whether the Systematic Problem Solving Strategy could improve the student’s learning achievement. The aim of the research was to improve the student’s comprehension on Algebra Limit Function subject In Mathematics, so their learning achievement also improved significantly. The research participants were the students of grade XI IPS 2 SMAN 1 Kerinci. The researcher was helped by a collaborator who was a Math Teacher at the same school. The study was done in two cycles with four stages, (a) Planning (b) Action (c) Observation (d) Reflection. The result of data analysis showed that the student’s average score in cycle 1 was 69 (65%). It became higher in cyle 2 to 83 ( 85%). There was significant improvement seen from the result of cycle 1 compared to cycle 2. It could be concluded that the implementation of Systematic Problem Solving Strategy on Algebra Limit Function subject improved the student’s learning achievement significantly. Therefore, it was suggested to Math Teachers to apply the strategy in teaching  as the alternative solution particularly in Algebra Limit Function subject

Metacognitive Ability

Seeing the differences in the results of several previous studies on metacognitive abilities in problem solving, researchers are interested in examining students' metacognitive abilities in problem solving in terms of gender differences. This problem is important to study because it aims to determine the implementation of the metacognitive abilities of male and female students in problem solvingThe purpose of this study was to determine the metacognitive ability of male and female students in problem solving using TIMSS questions at SMP Al-Falah Pesanggrahan Jangkar for the 2020/2021 academic year. This type of research is descriptive qualitative. The subjects of this study were one male student and one female student from class VII SMP AL-Falah Pesanggrahan who had the same mathematical ability. Data collection techniques in this study were interviews, mathematical ability tests and TIMSS questions. Data analysis in this study was analyzed on each data collection technique. The results of data analysis showed that there was no difference in metacognitive ability in problem solving between male and female students. The metacognitive abilities of male and female students have been used well in problem solving. Both of them can explain their thinking process in every stage of problem solving.   Keywords: Metacognition Ability, Problem solving, TIMSS questions, Mathematical Ability, Gender Difference.

<p class="AbstractEnglish"><strong>Abstract:</strong> This study aims to determine the interaction/influence of the application of the project based Double Loop Problem Solving learning model in improving Critical Thinking Skill and student Interpersonal Skill. This research is in the form of quantitative research and the sample used in this study is one class taken using Saturated Sampling techniques. The research class was treated using a project-based Double Loop Problem Solving learning model. The independent variable in this study is a project based Double Loop Problem Solving learning model, while the dependent variable is Critical Thinking Skill and student Interpersonal Skill. There are 2 kinds of data analysis techniques, namely data analysis techniques about Critical Thinking Skills and data analysis techniques about student Interpersonal Skills. The analysis of the hypothesis test of this study used the T-Test with a significance level of 5%. T-Test Criteria are as follows, Ho is accepted / H1 is rejected if T count is smaller than T table and Ho is rejected / H1 is accepted if T count is greater than T table. From the results of the TT-test for the first dependent variable Critical Thinking Skill T count = 18.77 and T table = 1.782, because T count is greater than T table, Ho1 is rejected, meaning that there is interaction/influence on the implementation of project based Double Loop Problem Solving learning model in improving Critical Thinking Skill. While the results of the T test for the Interpersonal Skill dependent variable obtained T count = 12.33 with T table = 1.782, because T count is greater than T table, Ho2 is rejected, meaning that there is interaction / influence on the application of Double Loop Problem Solving based learning models to improve Student Interpersonal Skills.</p><p class="AbstractEnglish"><strong>Abstrak:</strong> Penelitian ini bertujuan untuk mengetahui interaksi/pengaruh penerapan model pembelajaran <em>Double Loop Problem Solving </em>berbasis<em> project</em> dalam meningkatkan <em>Critical Thinking Skill</em> dan <em>Interpersonal Skill</em> mahasiswa.

In this chapter we review the history of mathematics-based approaches to problem solving. The authors suggest that while the ability of analysts to deal with the extremes of data now available is leading to a new leap in the handling of data analysis, information processing, and control systems, that ability remains grounded in the work of early pioneers of statistical thought. Beginning with pre-history, the paper briefly traces developments in analytical thought to the present day, identifying milestones in this development. The techniques developed in studies of computational intelligence, the applications of which are presented in this volume, form the basis for the next great development in analytical thought.
