Abstract

In the era of the industrial revolution 4.0, the education system has used technology to assist the learning process. Technology-based learning makes it easy for students and teachers to carry out learning activities. However, teachers have not been able to optimally develop students' potential, low student learning outcomes and low problem-solving abilities in students. Problem solving ability is very important for a student in learning science. Problem-solving skills in science learning are the main key to training students' scientific thinking in solving phenomena in science. So, it is necessary for a teacher to improve the learning model for those who are able to develop students' problem solving abilities. Problem solving learning is a learning model based on problem solving. In addition, the problem solving learning model helps teachers to be more creative in carrying out the teaching and learning process. This study aims to analyze the effect of problem solving learning models on students' problem solving abilities in science learning.

Abstract

The initial study that we carried out regarding the Kwanyar sub-district area, Bangkalan, East Java, shows the need to optimize land productivity and analyze the potential for farming to build the welfare of the people of the Kwanyar subdistrict. Preliminary spatial data analysis related to the topography as a result of Digital Elevation Model (DEM) data processing shows that: the Kwanyar sub-district is dominated by flat slopes (0-8°) compared to the northern region of the Kwanyar sub-district, while runoff water analysis shows a low flow coefficient (0- 0.25) which means that most of the Kwanyar area has low absorption capacity and a high potential for stagnant water. In addition, the Kwanyar region has a Regosol soil type. Regosol soil has a coarse texture and low organic matter, which makes it unable to properly hold water and minerals for plants, so it tends to be infertile. The initial study then became the basis for this research.
