Abstract

This research was motivated by the anxiety of students of mathematics education study program towards HOTS mathematics problems. This anxiety affected the quality of their thought processes. Therefore, the purpose of this study was to analyze the thought processes of students with anxiety feeling about HOTS math problems based on Mason's work phases, namely entry, attack, and review. This research was a qualitative descriptive research. The datas in this study were obtained from mathematics anxiety questionnaire, HOTS mathematics test and interviews. Based on the analysis of the data collected, it could be concluded that students with high levels of anxiety fulfill the phase “entry“ only on aspect “want”, the phase “attack” was only in the aspect ”try”, but did not meet the phase “review”. Students with moderate levels of anxiety met the phase “entry” at aspect “know”, “want” and “introduce”, phase “attack” on the aspect “try” and “maybe”, but did not meet the phase “review”. Students with low anxiety levels met the phase “entry” at aspect “know”, “want” and “introduce”, the phase “attack” on the aspects “try”, “maybe” and “introduce”, but also does not meet the phase “review”.

Abstract

Farmers are concerned about the problem of drought in agriculture because it will disrupt the production system and cause losses. In 2015, the Indragiri Hulu area experienced a drought on 273 hectares of agricultural land. This area is part of the Indragiri River Watershed in Riau Province. To prevent the impact of future droughts, forecasting is required. The level of drought is influenced by rainfall, so the Seasonal Auto Regressive Integrated Moving Average (SARIMA) method is used to model rainfall data. In addition, the Standardized Precipitation Index (SPI) is also used to analyze the drought index. After the analysis, it was found that the best model in forecasting is SARIMA model (1,0,1)(2,1,1)12 with an average residual square of 18.0175, and the drought index in the Indragiri watershed is currently included in the  "Normal" category. The results of this forecasting are expected to assist the Riau Province National Disaster Management Agency in anticipating and mitigating the impact of future drought disasters.

Abstract

Padang city has been in the red zone (high risk) and orange zone (medium risk) against the transmission of the Covid-19 virus for several months. This is due to the lack of community discipline in complying with health protocols. The existence of the Andalas University Hospital Laboratory in Padang City which has the tools to issue the SWAB test results also results in data being obtained very quickly and data collection is more accurate. To predict the number of new cases of Covid-19 patients, research on forecasting is necessary. One method that can be used is the Seasonal Autoregressive Integrated Moving Average method or abbreviated as SARIMA. This method was chosen because the data shows a weekly seasonal pattern. The data used are daily data from 2 August 2020 to 6 January 2021 obtained from the Padang City Health Office . The results showed that the SARIMA (0,1,1) (0,1,1) 7 model is the best model with parameter estimates that are significantly different from zero, so that it fulfills the white noise assumption with a Means Squared Error value of 3.46731. Forecasting results for the next month show that cases of Covid-19 patients are still fluctuating, ranging from 20 to 66 people. For this reason, efforts from the local government of the City of Padang are needed in disciplining the community so that the conditions of Padang City can immediately turn into a green (safe) zone from Covid-19.

Abstract

This research is motivated by the weak mathematical communication skills of students in participating in mathematics learning. It is known that during the learning process, students are unable to express their opinions, and their mathematical communication skills are weak, requiring appropriate learning models to improve students' mathematical communication skills in mathematics learning. This study aims to determine the effect of the auditory intellectual repetition learning model on students' mathematical communication skills in mathematics, particularly in the statistics material in class X SMAN 14 Padang. The type of research is Quasi Experiment (quasi-experiment), and the research design used is Nonequivalent Control Group Design. The experimental class was treated using the auditory intellectual repetition learning model, while the control class used conventional methods. Based on the research results, the Mann Whitney U test analysis showed a value of 0.001 < 0.005. Therefore, it can be concluded that H0 is rejected and H1 is accepted, which reads “there is a significant influence of the learning model on students' mathematical communication skills in mathematics subjects in statistics material in class X SMAN 14 Padang.”
