Abstract

Has done research for the purpose of to determine Has done research for the purpose of to determine the relationship between the understanding of the concept of students with the ability to solve problems of Newton's laws class X student of SMA Negeri 1 Angkola Barat in the academic year 2017, the second, to determine how much stronger relationship understanding of the concept with the ability to solve problems of Newton's laws class X SMA Negeri 1 Angkola Barat in the academic year 2017, the third, to know how big contribution to the understanding of the concept of the ability to solve problems of newton's laws of class X student of SMA Negeri 1 Angkola Barat in academic year 2017. This research was conducted in SMA Negeri 1 Angkola Barat with the population of all students in class X IPA at SMAN 1 Angkola Barat and a sample was taken 30 students of class X IPA 2 by using purposive sampling mehtod. Research using correlation method and data were analyzed by statistical methods. The study used a data collection tool that tests Understanding Concepts and Problem Solving Ability Test Physics. The study used data collection tool is calibrated through validity and reliability test. The results of the study there is a relationship between students' understanding of the concept with the ability to solve problems of Newton's laws of class X student of SMA Negeri 1 Angkola Barat Academic Year 2017. After koefien consult with the correlation table "r" of Pearson Product Moment, turned out rhit > rtab. Both at the level of 0.01 (1%) and 0.05 (5%), ie 0.975> 0.361 and 0.975> 0.463. While, testing the significance turns thit > ttab ie 23.44> 1.9958. While, the contribution of variable X to variable Y by 95.06%.

Abstract

This study discusses the improvement of the ability to form physics hypotheses of class XI students of SMA 3 Sibolga through the Mastery Learning model in statistical fluid material. This type of research is a Classroom Action Research (CAR) consisting of 2 cycles. The research subject was class XI IPA 2 which tested 30 people. Learning Tools used in this study are Learning Implementation Plans (RPP), Teacher's Guidebook (BPKS), Student Worksheets (LKS), Test Instruments, Observation Sheets, and activities. While the test used is an essay form test that has been tested with the reliability of the first cycle test of 0.74 with a high level of reliability and the second cycle test of 0.89 with a high level of reliability. And both tests each have 5 valid questions. The results showed that the test results formulated the students' hypotheses by applying the Mastery Learning model in the first cycle obtained a fairly good percentage of 66.67% and in the second cycle increased to 83.32% with the indicators succeeding in getting 80%. Then for the results of observations of activities in the first cycle obtained levels of student activity of 69.63% "Enough" and in the second cycle there was an increase in student activity to 88.63% "Good", Indicators of achieving activities in cycle II also produced 80%.

Abstract

Currently the development of science and technology is very rapid in supporting human activities both in the fields of industry, agriculture, education, health, and so on. The people of Sibiobio village who tend to farm and are still lacking in utilizing the development of science and technology, especially in the fields of agriculture and education, need training activities. Given the importance of the role of science and technology in improving the welfare of the community, one of the goals of this community service is to improve human resources in the village. This service activity is carried out by conducting a survey first to find out the main problems in the area. Then an agreement was made on the time of the activity, and the main targets in the implementation of this training activity were Naposo nauli Bulung (NNB) and several village and community officials. Training activities are carried out by providing material with powerpoints, carrying out demonstrations, as well as direct practice or training to participants. Indicators of success in this training activity are the participants' responses to the activities, participants' understanding of the material and the use of science and technology, behavior change, and improvement in organization. Based on the evaluation, it was concluded that the participant's response was very high and it was hoped that there would be activities again with different topics. The participants became more aware of how to use it and some NNBs were able to develop science and technology to support their daily activities. Based on this, indirectly also changing the behavior of the participants and changing a monotonous organization to be useful with many activities to be carried out.
