Modeling Data Containing Outliers using ARIMA Additive Outlier (ARIMA-AO)

The aim this study is discussed on the detection and correction of data containing the additive outlier (AO) on the model ARIMA (p, d, q). The process of detection and correction of data using an iterative procedure popularized by Box, Jenkins, and Reinsel (1994). By using this method we obtained an ARIMA models were fit to the data containing AO, this model is added to the original model of ARIMA coefficients obtained from the iteration process using regression methods. This shows that there is an improvement of forecasting error rate data.Comment: 13 page

Effect of Animation and Review Video Making (Arvima) in Non-classical Learning Model on Independent Learning and Students' Learning Outcome

The non-classical learning model used in this study was a jigsaw type cooperative learning model with the assignment treatment of making learning material video which is expected to make it easier in finding knowledge in teaching materials, with the creativity of students' forming skills. The purpose of this study are to determine: (a) the effect of animation video and review video making in non-classical learning model on the ability to learn independently of students of the chemistry education study program at USN Kolaka, (b) the effect of animation video and review video making in non-classical learning model on the ability of spatial independence of students in the chemistry education study program at USN Kolaka, and (c) the effect of animation video and review video making in non-classical learning model on the learning outcome of students in the chemistry education study program at USN Kolaka. This research was a quasi-experimental research (quasy experiment) with a posttest only research design. The research population was students in the IV and VI semester of Chemistry Education Study Program. The instrument used was a questionnaire of learning independence, spatial ability and learning outcome

Analysis of the Relationship Between Learning Independence and Students` Creative Attitude Towards Learning Outcomes in Chemistry Learning

This study aims to describe the description of learning independence, students' creative attitudes, and the relationship between learning independence and students' creative attitudes towards learning outcomes in class X chemistry learning at SMA Negeri 6 Palu. This research was conducted from April to June 2021. The research method used was descriptive research. The sampling technique is purposive sampling. The population in this study were all students of class X with a total of 90 students, the samples used were students of class X IPA 2 SMA Negeri 6 Palu in the academic year 2020/2021 as many as 30 students. The research instrument used in this study was a learning independence questionnaire and a creative attitude questionnaire compiled using a Likert scale, and using MID learning outcomes in semester 2 of chemistry class X IPA 2. Based on the results of the study, there were 3 categories of descriptions of independent learning and creative attitudes students are high, medium and low. The results of the calculation of the correlation coefficient between learning independence and student learning outcomes are low (rcount) 0.260. The relationship between creative attitudes towards student learning outcomes is moderate (rcount) 0.457 at the moderate level. Based on these data, it can be concluded that the creative attitude of students to support learning success is more positive than student learning independence. The results of this study are expected to be a source of information regarding the relationship between learning independence and students' creative attitudes towards learning outcome
