Implementasi Metode Winter untuk Forecasting Pertumbuhan Jumlah Penduduk: Studi Kasus Wilayah Provinsi NTB

This research aims to analyse the acceleration of population growth based on gender in West Nusa Tenggara Province (NTB) using the Forecasting system by constructing the winter's method in the shape of the Multiple Forecasting System (G-MFS) based on Matlab by calculating the period indicator for accuracy to find time series data in the year 2020-2029. At the simulation stage, researchers used the population and gender ratio data in NTB Province in 2009-2019. The method used in conducting research is to use the winter's method. The evaluation of Forecasting results is done by calculating the average error value using the Mean Absolute Percentage Error (MAPE) method. From this study obtained the most optimal parameter value on male data namely ʌ, β and γ sequential values of 0.9, 0.5 and 0.9 while in female data, the value of ʌ, β and γ respectively, 0.2, 0.1 and 0.5. Then with the value of the parameter obtained MAPE value in male data of 1.7785% and in female data of 0.89034%.

Kemampuan Komunikasi Matematika: Studi Komparasi Pembelajaran Number Head Together (NHT) dan Media Power Point (PPT)

This research is a quasi-experimental study that aims to determine the comparison of students' mathematical communication abilities with the cooperative learning model of the NHT and PPT media in class VII SMP Negeri 02 Ngabang. The population in this study were all students of class VII SMP 02 Ngabang consisting of 3 classes. The sample in this study was taken by using the Random Sampling Cluster technique. Class VII A as class I experimental class with 24 students and class VII B as a experimental class II with 24 students. The instruments used were pretest and posttest in the form of description. Data analysis uses the t test with a significance level of 5%. The results showed the average posttest for the NHT class was 72.5 and the average posttest for the PP class was 66.666. From the posttest hypothesis test results obtained t hitung> t tabel (1.9522> 1,667). Because t_hitung> t_tabel, H_0 is rejected and H_a is accepted. This means that students' mathematical communication skills taught with the NHT are better than using Power point media.

Construct 2 Berbasis Android Sebagai Bahan Ajar Relasi dan Fungsi

This research and development uses the ADDIE model which includes 5 steps namely analysis, design, development, implementation, and evaluation. The results of this study are android-based M-learning teaching materials assisted by Construct 2 on the subject matter of relations and functions. This teaching material gets an assessment in the valid category with an average value of 3.40 in the material experts and includes a valid category with a value of 3.54 in the media expert. In small-scale trials followed by 3C and 5D classes with 10 students each getting an average score of 3.47 with very interesting criteria. In the large-scale field trial which was attended by 30 students of 3E grade the average score of attractiveness was 3.57 and grade 5C with an average of 3.38 with very interesting criteria. Effect size test results in class 3E with 0.56 results and in class 5C of 0.57 with moderate criteria. Based on these results it can be concluded that the Android-based M-learning teaching material is assisted by construct 2 on the material of the relation and the function is feasible and effective to be used as a learning aid.

Implementasi Interpolasi Newton Gregory pada Model Matematika Penyebaran Virus Corona di Indonesia

The purpose of this study is to analyze the development of pandemics in all regions of Indonesia. the method used is the Newthon Rapshon interpolation method, to determine the percentage of the development of the corona virus spread in Indonesia and the method using a qualitative method by analyzing and describing data that has been simulated. The results obtained are predictions of covid-19 cases that occur in May, June, July until August, ie in those months there will be an increase in all cases that occur about this pandemic namely positive patients, recovered and died will continue to increase with a positive final conclusion> cured = died and obtained pn (x) = 2 for patients cured, pn(x) = 0 for cured and dead patients, in this study found pn(x) = 0 because the vaccine for this pandemic has not been found so the possibility of recovery and death has not been obtained its MAPE value, but an increase in cases of recovery is predicted to continue to occur as well as cases of death.
