The Effect of Concept Sentence Learning Model on Students' Learning Outcomes

This study aims to determine the influence of using the Concept sentence learning model on the learning outcomes of Tamansiswa Pematangsiantar Middle School students. The method used in this study is an experimental method with a randomized control group pretest-posttest design. The research was carried out in three stages, namely the preparation stage, the implementation stage, and the final stage. Data analysis was carried out quantitatively, namely descriptive and comparative. The data analysis technique used is descriptive analysis and inferential statistical analysis. Data testing was carried out in two stages, namely the analysis requirements test (normality test and homogeneity test), and hypothesis testing was carried out by statistical t-test. Research data were analyzed using SPSS version 21.0. From the results of the study, the average value of the post-test for the experimental class was 88.68, while the average post-test for the control class was 85.13. From the results of testing the hypothesis obtained tcount (2.338) > ttable (1.992), then Ho is rejected and Ha is accepted meaning that there is a significant influence of applying the Concept Sentence learning model to student learning outcomes at Tamansiswa Pematangsiantar Middle School. It was concluded that there was an effect of applying the Concept Sentence learning model to the learning outcomes student of senior high school Tamansiswa Pematangsiantar

The Effect of Multimedia Utilization on Increasing Students Learning Outcomes

This study aims to determine the effect of using multimedia on improving student learning outcomes on excretory system material in class XI SMA YPK Pematangsiantar. The total population of 64 people consisting of 2 classes and samples were taken by random assignment so that 2 classes were obtained, namely the control class (XI-3) 32 people and the experimental class (XI-1) 32 people. The control class was treated without using multimedia power point and the experimental class was treated using multimedia power point. Data analysis was carried out by finding the average (, standard deviation (S) and hypothesis testing (t test) at the significance level = 0.05. From the results of the study, the average post-test for the control class was 88 and the experimental class was 90.13 with a difference in learning outcomes of 2.13. From the results of hypothesis testing (t test) obtained tcount (2.790) > ttable (1.99) at a significance level of 0.05 and degrees of freedom (dk) = 62, then Ho rejected and Hais accepted, meaning that there is an effect of using multimedia power point to improve student learning outcomes on the material of the human excretory system in class XI SMA YPK Pematangsiantar. It was concluded that there was an effect of using multimedia on improving student learning outcomes in the material of the human excretory system of class XI SMA YPK Pematangsiantar

Analysis of Lettuce (Lactuva Sativa L) Farming Efficiency, Jaranguda Village, Merdeka District, Karo Regency

The research aims to know the effect of factors of production on the production of lettuce farming, to determine the level of technical, allocative, and economic efficiency of the use of production factors of lettuce farming and to determine the level of profit that can result from lettuce farming. The reason for choosing the area was because the majority of the population were cultivating lettuce plants. The results showed that: the influence of production inputs (seeds, fertilizers, pesticides, labour and land area) significantly influence the production of lettuce farming. The level of efficiency in the use of production factors (seeds, fertilizers, pesticides, labour and equipment) has not been technical, price, and economically efficient. Net income per farmer amounted to Rp. 2,608,062.,63, per month amounted to Rp. 869,354. 21 when compared to the UMK of Rp. 2,829,558, the income of lettuce farming in the study area was relatively low
