Abstract

The aims of this study is to know the performance of agricultural extension in term of developing Bali cow business and the success of farmers in developing Bali cow business in Muna regency. Those respondents in this study determined by classified random sampling by proportional technique namely 10% performance of agricultural extension taken by census. Based on result the agricultural extension categorize as good (69,13%), whereas the successful of farmer in term of Bali cow production categorized as less success (53,02%), There is unreal relationship between the performance of agricultural extension and success of farmer, whereas knowledge, skill, motivation, act, range of place of living relate real positive toward the performance of agricultural extension. Conclusions of this study are performance of agricultural extension workers in this area is included in good category, and success of farmer categorize as less success. Performance of agricultural extension relates unreal positive success of farmer. Whereas knowledge, skill, motivation, act, range of place of living relate real positive toward the performance of agricultural extension

Abstract

This study aims to investigate the effect of Science, Technology, Engineering, and Mathematics-Project Based Learning (STEM-PjBL) and discovery learning on students' problem-solving abilities. The research is a Quasi-Experiment with a Nonequivalent Pretest-Posttest Control Group Design. The participants involved are 53 students of class X from a high school in Malang, where 28 students studied with STEM-PjBL, and 25 students studied with discovery learning. This research was conducted on the subject of impulse and momentum. In this analysis, researchers have developed problem-solving tools with a particular field approach to impulse and momentum topics in order to obtain an instrument with a reliability of  0.81. This instrument collects student problem-solving data before and after learning both in the experimental class and in the comparison class. Problem-solving skills data were analyzed using descriptive statistics and inferential statistics. The results showed a significant difference in the scores of students' problem-solving abilities in the experimental class and the comparison class (p<0.05). The problem-solving ability in the experimental class (Md=78.74) was higher than the comparison class (Md=70.00). In STEM-PjBL learning, students are better trained and challenged to solve problems in everyday life. Compared to the comparison class, learning in the experimental class is more able to accommodate students' ideas and make students more interested in learning. In conclusion, STEM-PjBL has a significant positive effect on improving students' problem-solving abilities rather than discovery learning.
