Abstract As one of the foundations in the development of technology, physics must be supported by experimental activities that are able to develop a scientist's skills, such as scientific reasoning skills. Experiments with cookbook methods that have been conducted in various experimental activities are considered not able to maximize the potential of students because it does not provide wide opportunities for students to explore. One of the solutions to develop the scientific reasoning skills of physics students is the problem solving-based experiment approach. The research was conducted by one group pretest-posstest design to 20 physics students as research sample. The research instrument used is the scientific reasoning instrument test developed by Lawson which is known as Lawson Classroom Test of Scientific Reasoning (LCTSR) and student work sheet instrument (LKM) containing problems in daily life and questions about: tools and materials, prediction, exploration, measurement, analysis and conclusions. The results show all aspects of scientific reasoning being measured, i.e. 1) conservation of matter and volume, 2) proportional thinking, 3) identification and control of variables, 4) probabilistic thinking, 5) correlative thinking, and 6) hypothetic-deductive thinking has increased. Based on the result of research can be concluded that the problem solving-based experiment can improve the scientific reasoning skills of physics students. Keywords: Problem solving, experiment, scientific reasoning skills Abstrak Fisika sebagai salah satu pondasi ilmu dalam perkembangan teknologi harus didukung dengan kegiatan eksperimen yang mampu menumbuhkembangkan keterampilan seorang ilmuwan, diantaranya keterampilan penalaran ilmiah dalam menyikapi fenomena alam. Eksperimen dengan metode cookbook yang selama ini menjamur dalam berbagai kegiatan eksperimen dipandang tidak mampu memaksimalkan potensi mahasiswa karena tidak memberikan kesempatan yang luas kepada mahasiswa untuk bereksplorasi. Salah satu solusi yang dapat menumbuhkembangkan keterampilan penalaran ilmiah mahasiswa fisika dalam bereksperimen ialah pendekatan problem solving-based experiment. Penelitian dilakukan dengan desain one group pretes-postes design kepada 20 mahasiswa fisika sebagai sampel penelitian. Instrumen penelitian yang digunakan ialah instrumen tes penalaran ilmiah yang dikembangkan oleh Lawson yang dikenal dengan nama Lawson Classroom Test of Scientific Reasoning (LCTSR) dan instrumen lembar kerja mahasiswa (LKM) berisi permasalahan dalam kehidupan sehari-hari dan pertanyaan arahan mengenai: alat dan bahan, prediksi, eksplorasi, pengukuran, analisis dan kesimpulan. Hasil penelitian menunjukkan semua aspek penalaran ilmiah yang diukur, yaitu 1) kemampuan konservasi materi dan volume, 2) berpikir proporsional, 3) identifikasi dan kontrol variabel, 4) berpikir probabilistik, 5) berpikir korelatif, dan 6) berpikir hipotetik-deduktif mengalami peningkatan, sehingga dapat disimpulkan bahwa problem solving-based experiment mampu meningkatkan keterampilan penalaran ilmiah mahasiswa fisika.

Taijiquan is a traditional Chinese sport that is classified as a moderate exercise. Recent studies have evaluated the effectiveness of Taijiquan in substance abuse rehabilitation. Objective. To test the rehabilitation effect of Taijiquan exercise in patients with amphetamine (ATS) drug dependence. Methods. The effect of Taijiquan intervention was tested by parallel control experiment: Taijiquan group (n = 38) and control group (n = 38). The factors between the experimental groups were the group (Taijiquan group and the control group), and the factors within the group were the test time (before and after intervention). Repeated measurement analysis of variance was used to compare the two groups, and the factors that may affect the results were included in the covariance. Results. Taijiquan exercise promoted the balance control ability of ATS dependent patients ( p = 0.014 , η2 = 0.064), increased the overall sense of health ( p = 0.029 , η2 = 0.100), vitality ( p = 0.030 , η2 = 0.056), and mental health ( p = 0.016 , η2 = 0.061), improved trait anxiety ( p = 0.028 , η2 = 0.053), and reduced drug craving ( p = 0.048 , η2 = 0.048). Conclusion. Taijiquan exercise is beneficial to the physical and mental recovery of dependent patients, and the physical and mental benefits of exercise may have an effect on drug craving, which is of the most important significance for addicts to quit drugs and prevent relapse. The study is registered on the Chinese Clinical Trial Registry (No. ChiCTR1800015777).

Six Sigma Approach

The objective of this research was to reduce defects in the forming process of fired clay floor tiles by modifying the parameter settings of the influential factors using the Six Sigma approach. The current process had 152,871.16 DPPM (Defect Parts per Million). The main cause of this problem was the rough surface problem in the forming process. The five steps of the Six Sigma quality improvement approach were exercised in this research, i.e. define, measurement, analysis, improvement, and control phases, respectively. This research started by studying in details of the production process to find relevant factors that could cause a rough surface defect. The main factors were selected and analyzed by Failure Mode and Effect Analysis (FMEA). After that, the settings of each factor were discovered by applying the Design of Experiment (DOE) approach. The results showed that the appropriate settings were the sieve size of pan mill setting to 18 Mesh and the size of sieve holes at pan mill setting to be uniformly distributed. It is found that the defect was reduced to 49,151.14 DPPM, which is 67.85% of the defect before the improvement.

The noise caused by rail corrugation seriously affects the operation quality of metro vehicles. In this work, the rail corrugation, interior noise and wheel–rail noise of a metro line were tested, and the test results were compared with those after two kinds of treatments. The results show that rail corrugation is the main cause of the abnormal interior noise. The interior noise in many sections exceeds the limit, where clear rail corrugations from 31.5~63 mm are found. When the train passes through the rail corrugation section, the interior noise shows a clear increase, and the maximum increase is higher than 25 dB(A). After increasing the lateral stiffness of the track and rail grinding, the interior noise is reduced by 11.4 dB(A). After a long renovation time, the interior noise is effectively equal to that when the renovation was completed. The research results of this work can provide a reference for rail corrugation treatment and noise control.

At present, there are a large number of quality improvement techniques, making it difficult for companies to decide which to apply. In this research, the paste preparation area of ​​a ceramic tile manufacturing company was studied, and the result of this stage is directly reflected in the quality of the final product. The general objective was to apply the Six Sigma methodology in the paste preparation process of a ceramic company; likewise, to evaluate the measurements of the variables that intervene in the paste preparation area of ​​the productive process of a ceramic company and the causes that affect the quality. The application of the six sigma methodology requires the application of statistical tools because the term sigma represents the standard deviation of a distribution and is key to know its variability (Sharma, Bhardwaj, & Kumar, 2013). The implemented methodology is the one proposed in the DMAMC cycle: Design, Measurement, Analysis, Improvement, and Control or DMAIC (Define, Measure, Analyze, Improve, and Control). The critical quality variables were established for each of the three stages of the pasta preparation area: raw materials, grinding, and atomization. The data obtained in the technological tests were organized in tables and graphs, to analyze the results qualitatively and quantitatively, using Minitab and SPSS. As a result, the evaluation of the paste preparation area is obtained, as well as the processing capacity of the different variables of the raw material stage, which exceeds 95%, except for the variables of loss by fire and viscosity. As for the grinding stage, the variable viscosity (Z = 1.45), with a processing capacity equivalent to approximately 85%. There are statistically significant differences. Finally, the variables of the atomization stage have a higher process capacity, 98%.
