Abstract

Semut Leptothorax acervorum memiliki karakteristik kehidupan sosial, diantaranya pembagian peran, keharmonisan, dan kompetisi betina-betina dalam perebutan hak reproduksi di koloninya. Kompetisi yang mematikan ini terjadi baik sesama gyne maupun gyne dengan pekerja. Berdasarkan fenomena yang terjadi pada koloni semut Leptothorax acervorum akan dibangun model matematika. Model ini dibentuk dengan membagi populasi semut menjadi tiga kompartemen, yaitu gyne, pekerja, dan jantan pada populasi Leptothorax acervorum. Fenomena yang menarik seperti kompetisi-kompetisi yang terjadi pada semut Leptothorax acervorum dianalisis dan kestabilan koeksistensi juga akan ditunjukkan secara analitik. Selanjutnya, untuk melihat pengaruh kompetisi terhadap koeksistensi dalam koloni akan ditunjukkan dengan simulasi numerik.

Abstract

Mathematical communication is a very important aspect that students must have if they want to succeed in their studies, so that mathematical communication really needs to be developed among students. In mathematical communication students can express ideas by communicating their mathematical knowledge both orally and in writing in the form of algebraic explanations, pictures, digrams or other mathematical models. This research aims to describe the level of students' abilities in mathematical communication. This research is a descriptive research with a quantitative approach. The results of the study revealed that overall the number of students who had written mathematical communication skills in the very good category reached 23.4%, the good category reached 19.1%, the fairly good category reached 25.5%, the less good category reached 21.3%, the bad category reaches 10.6%, and the average value of mathematical communication skills is in the pretty good category.

Abstract

A quality learning process is influenced by the learning model used. A learning process that only listens to the teacher's explanation, does assignments, and focuses on books causes learning activities to become passive and there is a lack of student interaction. This has an impact on student learning outcomes. One model that involves students in learning is the Search, Solve, Create, and Share (SSCS) model. This research aims to determine the improvement in junior high school students' learning outcomes after implementing the SSCS learning model. This type of research is quantitative using Experimental Quasi. The subjects of this research were one experimental class, namely VIII-3, and one control class, VIII-4, SMP Negeri 3 Aceh Besar, each with 33 students. Data collection techniques use tests. The research results showed that the increase in learning outcomes for experimental class students was higher than that of the control class. The experimental class achieved 100% of the indicators of learning success/completion, namely ≥75% of students achieved a KKM ≥75 and there was an increase in student learning outcomes. The N-Gain test results show an increase in the moderate criteria, namely the experimental class is 0.69 and the control class is 0.49. Based on the results of the analysis, it can be concluded that the learning outcomes of students taught using the SSCS learning model are higher than the learning outcomes of students taught using the conventional learning model.
