This study aims to determine the effectiveness of the PhET (Physics Education Technology) Simulation model of Problem Based Learning on the process and student learning outcomes in the Parabolic Motion material of Class X IPA of SMA Negeri 1 Remboken. This study was an experimental study with a population of Grade X students of Natural Sciences at SMA Negeri 1 Remboken, and a sample of 25 students was taken, with a pre-experimental one-groub pretest- posttest design. Data were analyzed from the results of the posttest, as well as from the assessment of science process skills and affective assessment criteria both 66% -79% and very good 80% - 100%. In the hypothesis test obtained tcount> ttable then H1 is accepted and H0 is rejected, meaning the average student learning outcomes using the Problem Based Learning model assisted by PhET simulation media is greater than the KKM. Based on the data obtained an average posttest score of 80.24 while the KKM determined from the school is 75. So it can be concluded that the Problem Based Learning model, assisted by PhET (Physics Education Technology) simulation media is effective on the process and learning outcomes of student physics.

Central Sulawesi is located between the boundaries of tectonic plates which are interconnected with one another. Some tectonic plates are located near Central Sulawesi, including the Indo-Australian plate, the Pacific plate, and the Eurasian plate. The interaction of these plates causes the formation of subduction and fault lines as locations that have the potential to become the center of an earthquake. Earthquakes at scale specific strength can cause infrastructure damage and fatalities. This has led to the importance of erecting earthquake resistant buildings based on the characteristics of ground motion which is Peak Ground Velocity and Ground Motion Prediction Equation method. The purpose of this study is to see the pattern of the relationship between Peak Ground Velocity and earthquake parameters, make an empirical equation of Peak Ground Velocity predictions and see the gorund motion in the Luwuk area with coordinate 2,5 °LS – 1,5°LU dan 119°BT - 127°BT used the Peak Ground Velocity and Ground Motion Prediction Equation method. The result shows the pattern is directly proportional to the relationship between earthquake parameters and the Peak Ground Velocity, and for the empirical equation obtained is log (PGV) = -3.8873 + 1.026975 x M – 1.34171 x log (R +17).

The mathematical model for paratrooper motion is formed based on Newton's Second Law where the change in momentum in a system is equal to the resultant force acting on it. This research is an experiment with analytical descriptive method, which aims to show which method is most effective for the root solution of the equation in determining the drag coefficient (c) of the parachutist's motion numerically using the graph method, the method for two, the false position method, the Newton- Raphson and the Secant method. Numerical analysis using Borland Delphi 7 program and data processing using Microsoft Excel program. The results showed that the graph method is only limited to determining the estimated value for the lower and upper limits that will be used in the method of the two-way method, the false position method, the Newton-Raphson method and the Secant method. It turns out that the Secant method is a more effective method in determining the drag coefficient (c) of the parachutist's motion, because there are only 4 iterations to obtain a c value of 16.8345.

The study is conducted with the ability to representation in understanding the concept of interference and diffraction. The purpose of this research is to map the ability of student representation. The types of representations used in this research are verbal representation, visual representation, and mathematical representation. Research is conducted using analytic descriptive methods. The study was conducted in the Manado state university physics department during the V semester of the 21-student physics education course. The data-gathering techniques use essays which consist of verbal, visual, and math. By research, it was found that the ability to the student was divided into three categories that were the singular representation category, the dual representation category, and the complex representation category. Data analysis shows a 9.5% for single representational ability category, 47.6 % category double representational ability, and 42.9% category complex representational ability. Therefore, a student's dual capacity of representation is more dominant than a single representation and complex representation

Physics learning is currently still dominated by teacher centered that the principle of learning interaction is oriented to the transfer of knowledge. The research do to determine the application of discovery learning models in improving student learning outcomes. This research was conducted at SMP Negeri 2 Kotamobagu for the subject of light and optical devices. The research method used was the classroom action research model of Jhon Elliot. Data collection was performed on 20 students of class VIII. Data analysis uses percentages based on mastery learning references. The results obtained showed that the application of discovery learning models can improve student learning outcomes and this is seen from the average value of the class. At meeting I the average value was 62, at meeting II 71.25 and at meeting III reached 80.25. The percentage of mastery learning also shows the same thing where at the first meeting the value of completeness percentage 65%, at meeting II 85% and at meeting III reached 100%. The results of this study concluded that the discovery learning model was suitable for use in learning physics in class VIII junior high school on the topic of light and optical devices

The development of technology is increasingly fast, spurring us to be more technology literate, includingin the field of education. This research was conducted to find out how effective the PBL model, based onmultimedia in improving science process skills and student learning result on uniform circular motion,compared to conventional learning. This study uses an experimental method with a pretest-posttest controlgroup design, and data collection techniques use multiple choice questions. The study population was allclass X IPA and with the Simple Random Sampling technique, obtained research samples. Class X IPA 1 asa control class and Class X IPA 3 as an experimental class. Before do the hypothesis test, a normality testand a homogeneity test are first performed. From the results of descriptive analysis, the average value of thecontrol class is 32 and the experimental class is 33. After being given treatment, an average value of controlclass 62 and the experimental class is 79. As for the science process skills, students experience an increasein each assessment indicator. So the use of PBL models based on multimedia, is effective in enhancingscience process skills and student learning result on uniform circular motion.

Activation of rattan charcoal is carried out to increase pore size and formfunctional groups. In this study, activated carbon from rattan has been made withdifferent activation times. The research objective was to determine the pore size andfunctional groups contained in the activated carbon of rattan with an activation time of 5hours and 10 hours. The solution used to activate rattan activated carbon is KOH 10 mlcharcoal 10 grams with a burning temperature of 1500C. The results of rattan activatedcarbon were characterized using SEM and FTIR to see the pore size and functionalgroups. The activated carbon sample of rattan with the activation time of 5 hours had apore size that was not too large and only a few were formed and the sample of 10 hoursof activation time had a large pore size. The samples for 5 hours and 10 hours ofactivation have the same functional groups, namely O-H, C-C, C-O, C-H.
