Guru sebagai ”aktor utama” dalam pembelajaran dituntut harus professional dalam bidangnya yaitu mendidik, membimbing, mengajar, menilai, mengembangkan diri, serta mengembangkan karya inovatif. Pemanfaatan teknologi yang dapat dilakukan dalam pembelajaran salah satunya adalah pengembangan multimedia pembelajaran. Pengembangan multimedia pembelajaran yang memanfaatkan teknologi dapat digunakan guru dalam mengembangkan karya inovatif untuk mendukung professionalismenya sebagai guru. Namun, tidak semua guru dapat melakukannya. Guru membutuhkan “tool” atau alat yang “mudah” yang dapat digunakan untuk mengembangkan multimedia pembelajaran yang memanfaatkan teknologi. Dengan menggunakan Visual Basic for Application (VBA) yang ada pada Ms.Power point, peneliti ingin mengembangkan sebuah “mesin” yang dapat meningkatkan performa Ms. Power point. Tujuan jangka panjang dari penelitian ini adalah untuk meningkatkan profesionalisme guru dalam bidang pengembangan karya inovatif. Dengan dikembangkannya Multimedia tersebut diharapkan dapat mempermudah kinerja guru dalam mengembangkan karya inovatif berupa multimedia berbasis TIK yang dapat digunakan guru untuk pembelajaran maupun karir sebagai Guru Profesional. Model pengembangan yang digunakan terdiri dari 4 tahap yang dikenal dengan model 4D. Hasil Penelitian ini adalah suatu produk multimedia yang dapat membantu guru dalam mengembangkan karya inovatif yang mendukung profesionalismenya sebagai guru.
This study was conducted to identify the types of students’ misconception, factors that cause students’ misconception, and to describe the problem-solving of students’ misconception in mathematical induction. The subjects of this study were 30 junior students of Mathematics Department of Faculty of Teacher Training and Education of Universitas Islam Malang, who take Real Analysis I course. With respects to the students’ performance, the results of the study showed that most students had difficulty in interpreting letter, notation, generalization, and rules application. The factors that influence the students’ algebra misconceptions in mathematical induction was the students’ lack of ability, the lack of willingness that hinder the students’ cognitive development, and the lack of learning motivation. In order to solve these problems, the researcher proposed a method called guided discovery method.
For Mathematics Education Study Program, Mathematics of Economics is a subject where Mathematics is applied in Economics. In this course, mathematical concepts and theories which have been studied in the previous semesters have to be applied in Economics that is new for the students. For this kind of subject, the lecturer has to be more creative in the class so that the lesson will be more interesting and understandable. The aim of this research is to know the improvement of learning motivation in Mathematics of Economics through the use of multimedia development using Visual Basic for Application (VBA) in the class. This multimedia is presented in the form of a game in Microsoft PowerPoint (PPt) program. Respondents of this study were 34 students of class A in the fourth semester of Mathematics Education study program of Teacher Training and Education Faculty at Universitas Islam Malang who were taking this course. This study uses a qualitative descriptive approach with data collection techniques using observation and interview techniques. The observation sheet and the interview guidelines used here are arranged based on indicators measuring learning motivation. The result shows that the use of multimedia development with VBA can improve the students’ learning motivation to study Mathematics of Economics. The recalling of mathematical concepts and theories which have been studied before can be more interesting in the form of a game, while the new Economics concepts and theories with the mathematical application inside can be understood easily in the form of competition that enhances the motivation.
The relation between cell and turbidity (cloudiness) in suspended form is studied intensively to facilitate the estimation of the cell number. A standard curve in turbidimetry has utility to compare the turbidity reading value for the determination of Saccharomyces cerevisiae cell number and using a model. A standard curve is a prospect in this issue for the cell that has an inherent inaccuracy in the method as well as spectrophotometry. This research is conducted to obtain a model for the standard curve using analysis and diagnosis of the linear regression which was measured the relative standard error (SE) value of the dependent variable by simulation of turbidity value and verification of the applied model. We obtained the smallest relative SE from one of the five datasets that resulted in less than 10% of the relative SE on the estimated cell number. Plotting all of the bivariate data resulted in a larger error on the scattered light intensity at the higher cell number value, and this characteristic was named heteroscedasticity. Application of turbidity method for cell enumeration per mL in the media was significant equal and lower coefficient variation than the result of verification by a viable method.
The study aims to investigate the relationship between the turbidity and density or the total suspended inorganic particles have been obtained many models. The live cells as the homogeneous particle are presumed to cause turbid in liquid media, and that has a linear relationship that can be utilized on the cell counting. The method for the term of clouded liquid form is the measurement based on the reflection and scattered of light, i.e., the turbidimetry. Knowledge attainment of microbial cell counting should be answered how many Nephelometric Turbidity Unit of the one cell. We work to obtain a turbidity model of cells in water-based media for the estimation of cell numbers. This paper aims to construct the computational structure on the turbidity modeling of Saccharomyces cerevisiae in pure water and to test a consistent model in liquid nutrients medium. The modeling was performed in systematized stages of the diagnostic-analysis-test; the regression assurances, the simulation of the lowest error, and the coefficient value itself of turbidity factors. We constructed an optimal analysis and diagnosis to create a computational structure of cell turbidity modeling. The measurement and stopping bivariate elimination of the simulation is a subsystem of the algorithm of obtaining and testing models. The first mathematics model is a standard curve on turbidimetry, and the second, turbidity mathematics model of cell growth in liquid nutrients medium. Both models have an equal coefficient of cell turbidity. The turbidity coefficient of cell growth time interval in the carbonyl diamide - potato dextrose broth is significant.
