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

This research uses a quantitative approach. This study aims to determine the increase in problem-solving skills using the Problem-Based Learning Model, which is better than what is taught through conventional learning assisted by Video Learning in Elementary Schools. The type of research used in this research is experimental. Data collection techniques in this study were carried out through tests, namely pre-tests and post-tests, in the form of problem-solving ability tests and observations of the learning. The pre-test was carried out before the learning took place, and the post-test was carried out after the learning took place on both experimental and control groups. This instrument consists of test questions to measure students' problem-solving abilities. Data were analyzed by comparing student scores obtained from student results before and after being treated with conventional learning. The study results concluded that the obtained t-table value could be written as follows; t-table with a significance level of 5% = 1.303 < t-count = 2.076 for t-count or ha is accepted and ho is rejected. This video-based PBL model is suitable for learning mathematics in elementary schools.
