Abstract:
This study aims to find out (1) the POGIL learning model effective on mathematical communication skills. (2) conventional learning models are effective against mathematical communication skills. (3) the difference between the POGIL learning model and the conventional model of mathematical communication skills. This research is quasi-experimental research with the research design of The Nonequivalent Posttest Only Control Group Design. The population in this study is all students of grade VII MTS Negeri 02 Kerinci. This study's sample consisted of an experimental class and a control class selected by a random sampling cluster. The research instrument is a test f mathematical communication ability, and the data is analyzed using one-sample t-test statistics and independent t-test samples. This study shows that (1) the POGIL learning model is effective on mathematical communication skills. (2) conventional learning models are ineffective against mathematical communication skills. (3) there is a difference between the POGIL learning model and the conventional model of mathematical communication skills.

Abstract:
Queuing is an activity where parties are waiting to get service. A queuing process starts from the time of arrival to the time of service. Queuing problems are often encountered in everyday life, including in Langsa City Hospital, especially in the cardiac clinic, which has the most patients. The majority of patients in the queue system are elderly (elderly), so good service is needed considering the physical condition of patients who have entered a vulnerable age. The queuing system analysis aims to determine the average number of patients waiting in the system and the length of service at the heart clinic of Langsa City Hospital. In addition, the queue system analysis can help the Langsa City Hospital design an operational service system so that the service process can run optimally. The queue structure model used is a single channel-single phase with the discipline type First In First Out (FIFO). From the queue model analysis results obtained, the cardiac poly care system has an average number of patients waiting at most occurs in the period 08.00-10.00, namely 14 people with a waiting time of about 56.28 minutes. This time is the busy working hour at cardiac poly with a busyness rate of 93%. From the simulation results with two servers using the same model, a busy rate of 50% was obtained with a reduction in the number of people waiting by 12.8 people with a waiting time of about 1.2 minutes.

Abstract:
North Sumatra is one of the endemic areas of tropical diseases, one of which is filariasis. Filariasis or elephantiasis is a disease transmitted through mosquitoes and can cause permanent physical disability for sufferers. In 2015, there were 127 filariasis sufferers. This number has increased to 164 patients in 2017. As a prevention effort, the government provides mass treatment for people living in endemic areas of the disease. Therefore, this study aims to determine the model of spread and the effect of treatment on these communities. This study uses an SEIR model consisting of susceptible humans (S_h), infected humans (E_h), infected humans (I_h), and immune humans (R_h). The data used is data on filariasis sufferers in North Sumatra in 2010-2019, obtained from the North Sumatra Health Office. The data were analyzed based on the equilibrium point, stability, basic reproductive ratio, and numerical simulation. The results showed that based on the SEIR model, filariasis treatment could suppress transmission in endemic areas.

Abstract:
Lack of independent learning is the background of this research. The research objective was to determine how independent student learning was after applying the Think Pair Square type of cooperative learning model. Qualitative descriptive is a type of research using an instrument in the form of an independent learning questionnaire. The subjects in this study were class XI RPL B students of SMK Negeri 1 Bukit Sundi who were registered in the 2019/2020 school year. Based on data analysis with data descriptions, it was found that student learning independence for each indicator was at a percentage of more than 59%. With strong criteria. So, it can be concluded that the students' learning independence is strong after applying the Think Pair Square cooperative learning model.

Abstract:
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)

Abstract:
The Miquel theorem is a theorem that applies to a triangle, namely the inner Miquel theorem and the outer Miquel theorem triangles—then developed on the quadrilateral. As of this writing, it is developed in any of the pentagons. Miquel's theorem development in any pentagon is divided into two cases, namely in the convex and non-convex pentagons. This process begins with the construction of the inner Miquel point in any triangle using the GeoGebra application. While proving the internal Miquel theorem for any pentagon uses a simple concept, namely the concept of circles and cyclic rectangles so that five circles intersect at a point called the inner Miquel point at any pentagon.

Abstract:
Mathematics is an essential subject to study so that it must be pursued in its implementation and possible. The existence of the covid-19 pandemic requires all learning activities to be carried out online. But in practice, online learning experiences several obstacles, especially in learning mathematics. For this reason, the purpose of this study is to describe the constraints in the online-based mathematics learning process (e-learning). This study uses a descriptive method with a qualitative approach. The subjects in this study were students of class VIII SMPN 1 Rawamerta. The research instrument was in the form of a student response questionnaire regarding online-based learning (e-learning), which consisted of seven closed questions and four open questions. Data collection was carried out by distributing the google link form to the student response questionnaire to the research subject. Data analysis was carried out descriptively by testing the validity of the data through triangulation techniques. The results showed that students' obstacles in online-based mathematics learning (e-learning) were technical and personal constraints. Technical constraints are in the form of an unstable internet network, internet quota, and teacher explanations that are not heard clearly. In contrast, unique constraints are the lack of students in understanding the learning material and feeling lazy to take online-based mathematics learning.

Abstract:
The computer 1 learning outcomes of the second-semester students of the Mathematics Education study program are low because the instruments used have not used instructional videos. A solution is needed in the form of the use of instructional videos. This study wanted to see whether or not there was an effect of instructional videos on the learning outcomes of computer 1. The quasi-experimental method used in this study was that the class A was the experimental class and class B was the control class. The sampling technique used is the saturated sampling technique, where all populations are used as research samples. The average similarity test was used in analyzing quantitative data, while the qualitative data were analyzed descriptively. The average similarity test results utilizing the t-test show where the value of tcount > ttable that 2,56 > 2,015, so it can be concluded that there is an effect of the use of instructional videos on computer 1 learning outcomes second-semester students of the mathematics education study program 2019/2020.
