The purpose of this study was to determine the effect of teaching aids PBL learning model on student learning outcomes Static Fluid material class XI Science. Researchers used two classes namely, the experimental class numbered 24 students and the control class numbered 24 students. Both classes were given tests so that researchers could know the initial abilities of students, then each treatment was given. The experimental class uses the PBL model assisted with teaching aids, the control class uses the conventional model. After being tested for the second class posttest, it was obtained tcount> t table = 9.077> 2.01174. So, through this study, researchers can conclude the learning outcomes of the Experimental class using the Problem Based Learning model assisted with props larger than the Control class using the Conventional learning model.

This research is quasi-experimental research aimed at determining whether Jigsaw's collaborative learning has a positive effect on the learning outcomes of Grade X SMK Negeri 2 PINRANG (on straight motion material) students. The research design was "Pretest-Posttest Control Group Design". The variables in this study are the learning model and the learning outcomes. The independent variable in this study is cooperative jigsaw learning and direct learning, while the dependent variable is student learning outcomes. The population in this study were all grade X SMK NEGERI 2 PINRANG students. The sample in this study consisted of two classes, namely Class X APH1 as the experimental class and Class X APH2 as the control class with the sampling technique by random sampling. There are 12 students in class X APH1 and 12 students in class X APH2 in each class. The results of the analysis show that the mean of the experimental class is 75 and the control class is 42.5 with a standard deviation of 9.29 and 15, respectively. The results of the SPSS analysis using the t-test show that the value of t => is t table = 6.38> 1.717144. Therefore tcount> ttable means that H0 is rejected and H1 is accepted.

This study aims to determine the effectiveness of using the Reciprocal learning model on critical thinking skills and student learning outcomes. This research was conducted at SMA N 1 Likupang North Minahasa. In this study, the sample was taken using a total sampling technique with class X MIA II as the research sample in a one group pretest posttest design. The instrument in this study used cognitive description tests in the form of pre-test and post-test to measure student learning outcomes and non-tests in the form of observation sheets to observe students' critical thinking skills during learning. The results of the study were calculated using the paired sample t-test from the results of the pretest posttest sig <0.001 and the n-gain test with an n-gain score of 0.66 and an n-gain percent value of 66.92. Then the average value of the observations in the form of a percentage of the initial critical thinking ability of 0.88 is included in the less active category and the final critical thinking ability of 2.53 is included in the active category. And the results of this study concluded that H_a was accepted, meaning that the use of the Reciprocal learning model was effective in improving students' critical thinking skills and learning outcomes

North Sulawesi is one of the areas that has had a fairly high level of seismic activity that has occurred, due to the position of North Sulawesi Island which is located close to the earthquake source. One of the parameters of an earthquake that can be calculated is the earthquake hypocenter.Determining the hypocenter of an earthquake is very important in the world of seismology. The Modified Joint Hypocenter Determination (MJHD) method was carried out for relocation of the earthquake hypocenter. To find out how the results of the Hypocentrum Location Correction using MJHD and the tectonic pattern of the Sulawesi Sea Plate subduction zone. . The results of relocation using the MJHD (Moodifide Joint Hysopcentrum) method showed better and more accurate data quality seen from the residual value (RMS) before (≥1 s) and after relocation (≤1 S). Based on the seimicity results of relocation using the MJHD method, it was found that the earthquake clusters were concentrated at a shallow depth of the range of 20 - 80 km. At a depth of 250 - 300 and a distance of 400 km, there is a seimic gap so that earthquakes rarely occur in this zone.

Cooling water has a role in the process of condensing steam from the turbine to the condenser. Cooling water has an effect on maintaining the vacuum pressure in the condenser, so that the steam going to the condenser is maximally condensed. This study aims to determine the effect of variations of the cooling water temperature on the efficiency and performance of the turbine.. The research begins by reviewing the turbine conditions and turbine specifications including the surrounding environment. The higher the cooling water temperature, the greater the efficiency achieved. When the cooling water temperature is 29.14℃ the turbine efficiency value is 72% with the turbine performance value achieved is 627.568 kJ/kg. When the cooling water temperature is 30.43℃ the turbine efficiency achieved is 80% with the performance value achieved is 570,994 kJ/kg. The results also show that the higher the cooling water temperature, the turbine performance value will decrease and vice versa if the cooling water temperature decreases, the turbine performance value will increase.

North Sulawesi has a fairly large geothermal potential, this is evidenced by the emergence of several types of geothermal manifestations, one of which is in the village of Tempang. The purpose of this study was to determine the microstructure of rocks and the types of rocks contained in the rocks in the manifestation area in the village of Tempang. The method that will be used in this research is to analyze in the laboratory using SEM-EDX and FTIR. The results showed that the mineral content and types of minerals around the geothermal manifestation in the form of steaming ground had 3 mineral elements, namely oxygen, silica, and aluminum. The percentage results from EDX for sample 1 contained Oxygen (O) 43.72%, Silica (Si) 54.12%, and Aluminum (Al) 2.16%. For sample 2, the content of oxygen (O) is 51.10% and silica (Si) is 48.90%. This is in accordance with FTIR measurements obtained that the mineral type of steaming ground rocks in Tempang Village is Quartz (SiO2).

This research was carried out to determine the application of project-based learning models with contextual approaches to the material of the equilibrium of rigid objects to student learning outcomes. The method used in this study is an experiment with the design of one grub pretest-posttest design. The research sample amounted to 25 learners. The data analysis in this study used SPSS 25. From the results of the data analysis obtained an average pretest value of 30.55 and a posttest value of 91.29. The results of the hypothesis test using the Test-t paired sample test obtained a sig value. (2-tailed) is 0.000<0.05. So the data shows that there is an increase in student learning outcomes using a project-based learning model with a Contextual approach. Thus it can be concluded that the average score of the results of learning physics learners who are given treatment by using the application of project-based learning models with a contextual approach is higher than the average physics learning outcome when not given treatment.
