Abstract

The aim of this paper is to find out empirically the relationship between readiness to learn mathematics and mathematics learning achievement in grade VII MTs Al-Masthuriyah Jakamulya, South Bekasi. This study uses a descriptive method with a survey technique in the form of a correlation study. The sample was taken from class VII-3 consisting of 34 students with purposive sampling technique. The research results obtained indicate that there is a positive relationship or correlation between learning readiness and mathematics learning achievement. This can be shown by the correlation coefficient rxy  = 0,863 and the regression equation  3,11+1,02x is obtained. The coefficient of determination shows that r2= (0,863)2=0,7448, which means that the contribution of the influence given to the learning readiness variable on the learning outcome variable in mathematics is 74.48%. The conclusion of this study is that there is a positive relationship between students' readiness to learn mathematics and learning outcomes in the chapter related to rectangular shapes for 7th grade students of MTs Al-Masthuriyah Bekasi Selatan.

Abstract

Mathematical models are often used to describe phenomena in the field of biology, such as the spread of infectious diseases, one of which is HIV/AIDS. The prevention of HIV/AIDS is through education on the dangers of HIV/AIDS, and ART treatment for HIV positive individuals to increase immunity. The purpose of this study is to analyze the dynamic mathematical model of the transmission of HIV/AIDS with ART treatment and education. This research is a literature study. This study develops the SITA model, by including compartments of susceptible individuals who are aware of the spread of HIV/AIDS and add several parameters to the model. Based on the mathematical model used, two equilibrium points are obtained, namely the disease-free equilibrium point and the endemic equilibrium point, the basic reproduction number and stability analysis around the stability point. Based on the data used, a simulation of the transmission of HIV/AIDS was obtained at both equilibrium points. The stability analysis shows that the disease-free equilibrium point is locally asymptotically stable if R01.

Abstract

Penelitian ini bertujuan untuk menerapkan analisis trend pada peramalan harga eceran rata-rata beras di kota Padang. Data yang digunakan adalah data harga eceran rata-rata beras di Kota Padang pada Juli 2020 – Desember 2021. Analisis trend merupakan suatu metode analisis yang ditujukan untuk melakukan suatu estimasi atau peramalan pada masa yang akan datang. Variabel penelitian yang digunakan pada ini adalah harga eceran rata-rata beras pada periode tertentu sebagai variabel terikat dan periode waktu dalam bulan sebagai variabel bebas. Ada tiga jenis model trend yang digunakan pada penelitian ini yaitu trend linier, trend kuadratik dan trend eksponen. Tingkat kesalahan dalam peramalan diuji dengan menggunakan mean absolute percent error (MAPE). Berdasarkan hasil perhitungan MAPE diperoleh model peramalan harga eceran rata-rata beras terbaik, yaitu menggunakan model trend kuadratik dikarenakan model trend tersebut mempunyai tingkat kesalahan paling kecil.
