Abstract

Differences in Students' Mathematical Concept Understanding Ability Using Problem Based Learning (PBL) Learning Methods With Expository Learning Methods. On the Material System of Linear Equations of Two Variables in Class VIII SMP Negeri 8 Pematangsiantar. This study aims to determine the difference in the ability to understand mathematical concepts of students using the Problem Based Learning (PBL) learning method with the expository learning method on the material of a two-variable linear equation system. The population in this study were all eighth grade students of SMP Negeri 8 Pematangsiantar . sampling , the experimental class research sample was obtained as many as 32 students. The instrument used was a learning outcome test in the form of description questions that had been carried out at SMP Negeri 8 Pematangsiantar. From the results of the study, the average pretest result = 30.29 and the average posttest result = 34.9. Then the homogeneity of the data was tested by using the homogeneity test of variance F hit = 1.77 < F (0.05; 29:30 = 1.89 with a confidence level of = 0.05 meaning the sample is homogeneous because F hit is not in the critical area. From the calculation results of the t hit price = 1.86 for = 0.05 and v = 59 and table = 1.67 it turns out that t hits are in the k-point area, because 1.86> 1.67. So it can be concluded that student learning outcomes are good Using Problem Based Learning Methods With Expository Methods on Materials Two Variable Linear Equation System (SPLDV) in Class VIII SMP Negeri 8 Pematangsiantar.

Abstract

This study aims to improve students' mathematics learning outcomes with the Learning Based Learning Model in the 2013 T.A 2021/2022 Curriculum. This research is a classroom action research conducted in two cycles. Each cycle consists of 4 stages, namely: planning, implementation, observation, and reflection. The subjects of this study were fourth grade students, totaling 35 people consisting of 15 males and 20 females. The object of research is the result of students' mathematics learning. Data were analyzed using descriptive statistics. The results showed that the Problem Based Learning learning model can improve the mathematics learning outcomes of fourth grade students in the 2013 Curriculum. This is known from the pre-cycle student learning outcomes with an average score of 60.50 and learning completeness of 42.85% in the low category. In the first cycle, the results experienced an average value of 68.85 and 51.42% learning completeness which was in the sufficient category. The research was continued in the second cycle and obtained an average score of 80.35 and a learning completeness of 82.85% which was in the high category and had met the criteria for indicators of research success. So, it can be concluded that the application of the Problem Based Learning learning model can improve students' mathematics learning outcomes.

Abstract

Based on the phenomenon that often occurs in the fifth grade of elementary school in mathematics, there are students' difficulties in understanding these subjects. In the study, there were several problems that students tended to be passive, only a small number of students were active in participating in learning. The process of learning mathematics in class V SD Negeri 015906 Lubuk Palas tends to be not optimal. This is because students do not understand the material and some students are not able to work on various questions so that student learning outcomes are still low. The purpose of this study was to improve the learning outcomes of fifth grade students in mathematics. The results of the study by applying the drill method to the fifth grade mathematics subject in the first cycle, obtained 43.47% of students who completed. in the second cycle the student learning outcomes who completed as much as 65.21% completeness learning outcomes have increased by 21.74% and have met the KKM standard 70 reaching 65.21% at the end of the cycle. From the results of this study, it can be seen that student learning outcomes have increased, it can be concluded that learning by optimizing the drill method can improve student learning outcomes in mathematics for fifth grade students at SD Negeri 015906 Lubuk Palas.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh kualitas pelayanan pembelian online shopee terhadap minat beli konsumen. Populasi dari penelitian ini adalah warga di Kelurahan Tong Marimbun Pematang Siantar dan dalam menentukan sampel yaitu melalui rumus lemeshow. Jenis penelitian yang digunakan dengan menggunakan pendekatan kuantitatif, dengan teknik pengumpulan data menggunakan kuesioner. Dalam penelitian ini uji penelitian yang digunakan adalah validitas, reabilitas, analisis korelasi, analisis deskriptif, regresi linear sederhana, uji-t dan koefisien determinasi. Hasil kuisioner yang telah di uji validitas dan reliabilitas, selanjutnya dilakukan uji normalitas data sebelum dilakukan analisis data. Teknik analisis data menggunakan teknik regresi sederhana. Dengan menggunakan program Statistical Product and Service Solution (SPSS). Hasil penelitian menunjukkan bahwa hipotesis yang diajukan diterima karena menujukkan hasil uji hipotesis positif dan signifikan. Berdasarkan pengujian yang dilakukan menggunakan Uji Parsial atau Uji-t. Koefisien regresi atau t-tabel adalah sebesar 4,636 > t-hitung untuk variabel kualitas pelayanan tabel yaitu 1,65845dan mengartikan adanya pengaruh kualitas pelayanan terhadap minat beli konsumen, dan signifikansinya yaitu 0,000 < 0,05, maka Ho ditolak dan Ha diterima. Hasil koefisien determinasi pada penelitian ini yaitu sebesar 0.173 artinya kualitas pelayanan pembelian online shopee berpengaruh positif dan signifikan terhadap minat beli konsumen sebesar 17,3%.
