Abstract

Based on BPS data in 2019, around 90% of Indonesians consume rice as the main product of their carbohydrate needs. With the fourth most populous country in the world, Indonesia's rice consumption in 2021 will reach 31.50 million tons. Indonesia's rice production is currently not able to supply the needs of domestic rice consumption. Therefore, the Indonesian government chose to import rice for supply the needs of domestic rice consumption. Forecasting method can help the government to reduce uncertainty about the future of rice productivity. This research will discuss the comparison of the forecasting results of fuzzy timeseries using chen and cheng models in forecasting rice productivity in Indonesia. The comparison based on the percentage of eror or in this research the MAPE value is used as an indicator. The MAPE value obtained using chen model is 18% and using cheng model is 12%. The result of data analysis found that the MAPE value using cheng model is smaller than using chen model. It means that the cheng model is more appropriate used in forecasting data of  Indonesia productivity rice. However the chen and cheng models both give good forecasting result because the MAPE value is less than 20%

Abstract

It is the role of teachers to increase the quality of learning. When the instructor wants to increase the quality of learning, reflective practice is an option. However, instructors' current practice of learning reflection is based only on classroom action research and is primarily concerned with enhancing learning models rather than paying attention to student replies. As a result, prospective mathematics teachers must be able to engage in reflection techniques based on didactical design research that emphasizes student reactions. This study employs a descriptive qualitative technique, with the subjects being Mathematics Education students at the University of Majalengka who are enrolled in the Kapita Selekta Mathematics course. Students experience translating scientific, mathematical knowledge into mathematics ready to be taught in schools based on the study findings. Every step in the process of becoming a mathematics teacher has an impact on pedagogical content understanding

Abstract

This research was a case study research with a qualitative approach. The subject of this study was 6 class VIII students of SMPN 1 Kota Malang. The instruments of this study were cognitive quest conflict test sheets, general interview instructions, validation sheets, and record tools. The data obtained in the form of the results of the subject's work, interview data on the subject, and field notes. The results of this study indicated that cognitive conflict of students with instrumental understanding in solving comparison problems occurs when: (1) students determine the formula matching the problem and (2) students do algorithmic calculations. Student cognitive conflict when determining the appropriate comparison formula was the awareness of the contradiction between the answers obtained from applying a comparison formula worth the concept of a reverse value comparison. Student cognitive conflict when performing algorithmic calculations were (a) awareness that the initial scheme is to simplify the comparison of the number of people, tables and days was incorrect because it cannot be applied to solve all problems of comparison and (b) awareness that the calculation scheme was looking for multiplication patterns the known comparison cannot be applied because it produces an answer that was not an integer
