Mount Tampusu, Minahasa Regency, North Sulawesi has geological conditions that are influenced by the geothermal system. Where the geothermal system has plate movement that affects it, one of which is the convergent plate movement, where two plates collide with each other, resulting in the potential for surface manifestation. This study aims to analyze the surface structure and discharge area or commonly referred to as geothermal manifestations based on the density of straightness and surface manifestations. The structure on the surface was analyzed by lineament density using the FFD method. It is assumed that the fracture or fault is associated with geothermal areas which are mostly difficult to identify because they are covered by surface manifestations. Faults and fractures are the pathways for the movement of hot fluids because they are assumed to be weak fields so that they can be clues to the location of the discharge area or manifestation. Based on the FFD and Remote Sensing Methods collaborated with satellite image data, the surface density and its relationship with the discharge area in the study area were known. Where there are 64.45 straight ridges and valleys in the area with density values ranging from 1.6 to 4.6.

The increasingly difficult educational challenges and needs in today's modern world require interactive learning. The research was conducted to know students' critical thinking skills (CTS) in the kinetic gas theory material. Another goal is, as an initial observation, to develop learning methods with guided inquiry learning models assisted by android-based 3D modules in kinetic gas theory material. The research population was all class XI students at Tuban 2 Public High School in 2022/2023 as majoring in Mathematics and Natural Sciences. The research was conducted in 5 classes with the same distribution of questions and questionnaires. As secondary data, the researcher added several articles relevant to the research. The results of this study using several questions on kinetic gas theory material for class X1 were that students needed to be more able to answer each question with indicators of critical thinking. The student's obstacle in answering the questions lies in the need for more understanding of kinetic gas theory material and the not yet maximal use of the method in the current teaching and learning process. The resulting inquiry learning in the future will change the CTS of Tuban 2 Public High School students in the kinetic gas theory.
