The energy crisis is one of the major challenges facing the world today, triggered by over-reliance on fossil energy sources, rapid population growth, and the threat of climate change. One technology that attracts attention is supercapacitors. The purpose of this study was to determine the effect of carbon activation using KOH with varying concentrations on electrical conductivity as a supercapacitor electrode. By using dehydration method, carbonization at 500℃. The chemical activation process is treated with variations in KOH concentration of 6M, 7M, 8M with physical activation in a furnace at 750℃. The test results of conductivity and density values show that the comparison with the increase in KOH concentration results in an increase in conductivity of 0.1012 S/m, 0.1694 S/m, and 0.3282 S/m. Accompanied by a decrease in density of 9.8810 A/

North Sulawesi is in a complex tectonic interaction which is the relative movement of three Eurasian macro plates, the Pacific plate, the Philippine plate, and the Maluku Sea microplate. The active tectonic movement results in high earthquake activity in the region of North Sulawesi and its surroundings. This results in the importance of accurate earthquake parameter information, one of which is by conducting research on local wave velocity. The purpose of this study is to determine the velocity of 1D P waves and relocate the earthquake hypocenter and determine the correction stations in North Sulawesi and surrounding areas with coordinate boundaries 0.17166°S- 2.742781°N and 119.5212°E- 125.5067°E using the Couple Velocity-Hypocenter method with Velest software. The results of simultaneous inversion processing are carried out until the 50th iteration which obtains the wave velocity fluctuates at several depths but in general, the denser layers of the earth's compilers will increase the wave velocity, the improvement of the RMS from an average of 1.71 to 0.49 and the correction of the stations obtained is at intervals of 0.39 to 20.91.

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.
