Some Infiltration Capacity Unit of Land in Manado State University as Lectures References

Abstract

This study aims to 1) explore concepts and processes of the science of infiltration in a place that varies (slope and vegetation plants) at UNIMA 2) designing concepts and processes of the science of infiltration as lecture references. This study was carried out in June 2019 at the land of the State University of Manado. This study uses explorative research. The results of a measurement of infiltration are the land that has slope 10 0 and dampness 20% as well as in the dominance of grass has the highest rate of infiltration whereas the land that has the texture of the solid land (clay) and nothing plants has the lowest rate of infiltration. Exploring facts in the infiltration can be connected with concepts and processes of science in the form of a matrix. Designing concepts and process science of infiltration such as the material relating to infiltration, the description of the concepts of science on infiltration, and using 3 procedures of explorative in worksheets as a reference in learning processes and practical work in land science courses. The conclusions are concepts and process science of infiltration of covering physics (gravitation, capillarity, the collision on the ground, the mass of raindrops, the mass of the land, the intensity of light, free fall, the dampness of the land), chemistry (the content of rainwater chemicals, heat energy, soil pH), biology (evaporation, kinds of roots, hydrology). It can be in the form of a matrix as well as design concepts and process science of infiltration such as material and worksheets as lecture references inland science courses.

“…Clay soil is a type of soil that quickly saturates in wet conditions and have tight pores (Stanturf and Schoenholtz, 2019). If it rains hard enough will result in the infiltration process running slowly so that it will cause puddles of water on the surface (Mamonto et al, 2020).…”
