The distance learning process is something new for students, so there needs to be an adaptation for students so that they can learn well and can absorb the material given well. Therefore, this study will analyze the percentage of interest level and motivation to learn mathematics of mathematics education study program students at Almuslim University during the Covid 19 pandemic. The method used is a case study qualitative research with a population of all students of the Almuslim University mathematics education program. Data collection techniques are using a questionnaire of student interest and learning motivation and interviews. The results obtained were that the average interest and motivation of students in taking online lectures was 66.8%. Then the average student learning outcomes during online learning was 82.36%, this indicates that the learning outcomes of the Al-Muslim University Mathematics Education Study Program students were in a good category. So it can be concluded that if the students' interest and motivation are good, it will also increase the learning outcomes obtained. The relationship between online learning and student learning interest and motivation shows a strong relationship, which is 66.1%. In addition, the relationship that the online learning process has with student interest and learning motivation shows a positive relationship, which means that if the online learning process increases better, student interest and learning motivation will also increase.
This study aims to determine whether there are differences in the learning outcomes of mathematics education students at a university in Aceh who are taught using geogebra applications with students who are taught using conventional learning methods in the transformation geometry course. This research uses a quantitative approach with a true experimental type of research. The population in this study were all students of mathematics education at Almuslim University. While the samples used were students who took the Transformation Geometry course. The sample used in this study amounted to 60 people. Furthermore, the students were divided into 2 classes, namely 20 people into the experimental class and 20 people into the control class. In the experimental class, learning uses the geogebra application and in the control class using conventional learning. The results obtained show the difference in the average learning outcomes in the two classes. The difference in learning outcomes of the two classes can be seen by using the t-test independent sample test. These results indicate that the value of Sig. (2 Tailed) < 5 % . As for the value of Sig. (2 Tailed) of 0.000. This means that H0 is rejected. Thus, it can be concluded that the average student learning outcomes on the transformation geometry material in the control class are included in the less criteria. While the average student learning outcomes on the material of transformation geometry using the geogebra application are included in good criteria.
This study aims to create a mathematical model that can be used to predict the amount of oil palm that will be produced at PT. Socfindo in Aceh Tamiang Regency in the coming period. The data used is data on the amount of oil palm that is ready to be produced every month in 2012-2015. The method used is the ARIMA method. The selection of this method is based on the data used, namely time series data. Before carrying out further testing, first, ensure that the data used meets the stationary state. From the test results, it is found that the data used fulfills the stationary state, then it is found that the MA (1) model can be used to predict the time series data. Furthermore, we obtain a model that can be used to predict the volume of oil palm production at PT. Socfindo is: Z_t = a_t-0.4096a_ (t-1) +521.57 With a_t ~ N (0; 29192.72)
Penelitian ini bertujuan untuk mengetahui kemampuan koneksi matematis siswa dengan menggunakan metode Ekspositori pada materi trigonometri kelas X di MAN 1 Bireuen. Penelitian ini menggunakan pendekatan kualitatif, dengan jenis Penelitian Tindakan Kelas (PTK). Sampel dalam penelitian ini adalah siswa kelas X IPA¹ berjumlah 25 orang siswa, semester genap tahun ajaran 2020/2021. Dari hasil tes siklus I diperoleh data siswa yang mendapatkan skor adalah 64%, sedangkan pada siklus II diperoleh 92 %. Dari hasil tersebut terjadi peningkatan sebesar 28%. Hasil observasi aktifitas guru pada siklus I adalah 82,7% meningkat menjadi 95,4% pada siklus II. Sedangkan hasil observasi aktivitas siswa siklus I adalah 84,5% meningkat menjadi 93,6% pada siklus II termasuk ke dalam kategori sangat baik. Dengan demikian kriteria keberhasilan belajar dan proses pembelajaran siklus II sudah berhasil serta hasil wawancara siswa menunjukkan bahwa siswa senang belajar matematika pada materi trigonometri melalui metode Ekspositori. Hal ini dapat disimpulkan bahwa metode pembelajaran Ekspositori yang telah dilaksanakan dapat meningkatkan kemampuan koneksi matematis siswa pada materi trigonometri kelas X IPA¹ di MAN 1 Bireuen.
The aim of this research is to provide the results of ARIMA modeling on rainfall data in Langsa City in 2017-2021. The initial stage of ARIMA modeling is the identification of data stationarity. Meanwhile, stationarity in the mean can be done with data plots and ACF forms. Identification of ACF and PACF forms from data that is already stationary is used to determine the order of the alleged ARIMA model. The next stage is parameter estimation to see the suitability of the model. The diagnostic check process is carried out to evaluate whether the residual model meets the white noise requirements and is normally distributed. The Ljung-Box test is a test that can be used to validate white noise requirements. Rainfall data forms a stationary time series. Furthermore, from the model fit test it was found that the MA(1) model was suitable for predicting the model. Meanwhile, AR(1) and ARMA(1,1) are not used to predict because they do not meet the model fit test. The model obtained with the MA(1) model is as follows, namely .
