This study was proposed to get the solution of the Schrodinger equation with cotangent hyperbolic potential in the presence of minimal length by using the hypergeometric method. By getting the numerical results with the help of Octave software, we can analyze nonrelativistic energy. The visualization of wave function was obtained using Matlab software. The result is defined as the larger of minimal length, the width of potential V1, and the angular momentum was included, the energy is increasing as well. The larger of the width of potential V0 affected the decrease of energy in this system.

The research aims to describe the application of project based learning (PBL) models to improve learning achievement, and to find an increase in learning achievement. This study uses a quantitative descriptive research approach to the type of classroom action research. The research data were obtained using an observation sheet of student learning activeness and a job grading sheet turning students. The application of PBL uses the model proposed by Carr and Kemmis where each cycle consists of four steps, planning, action, observation, and reflection. The results showed that the increase in student learning was illustrated in the pre cycle 46% (sufficient category) increased to 60.5% (good category) in cycle 1 and again increased to 79.7% (very good category) in cycle 2. Improved learning achievement students with a minimal completeness criteria score of 61% in the pre cycle increased to 75% in cycle 1 and again increased in cycle 2 to 93.8%.
