Abstract

By conducting an analysis of the influence of solar radiation temperature on the output power of a 150 Wp Pematangsiantar solar cell whose energy source comes from renewable energy, which is the sun, it is hoped to help the community's maximum needs by obtaining it directly from solar energy, in addition to being cheap, the use of solar energy has never exhausted, the maintenance cost of Solarcell is also very reasonable and not least it does not produce pollution that can damage the environment. This research aims to find out the performance of a 150 Wp solar panel in producing electricity in the form of current, voltage and power to charge a battery with a capacity of 12 V 7 Ah. Research data collection was carried out at 08.00 WIB - 17.00 WIB. The test to determine the current, voltage and power in this study uses several components, namely a 150 Wp solar panel, solar charger controller, battery, voltmeter and ammeter Testing of a 150 Wp solar panel as an alternative energy source and data taken every hour for 9 hours. The magnitude of the current and voltage from the solar panel can be read directly. Each solar panel has a different level of efficiency. In general, solar panels on private residential solar systems have a standard temperature of 25°C (77°F), with a general temperature range between 15°C and 35°C. It is in this temperature range that solar panels perform best. The limit point for solar panel efficiency is 65°C (149°F). Above this temperature, the performance efficiency of the solar system can be disrupted due to the drop in voltage produced.

Abstract

This research aimed to analyze the influence of the Project-Based Learning (PjBL) learning model integrated with ethnoscience on student learning outcomes. The method used was a quasi-experiment with a pretest-posttest control group design. The research sample consisted of two classes of students taken randomly, where one class used the ethnoscience integrated PjBL model and the other class applied conventional learning methods. Data was collected through learning outcomes tests and analyzed using the t test to determine significant differences between the two groups. The research results show that the application of the ethnoscience integrated PjBL model provides a significant improvement in student learning outcomes compared to conventional methods. This research concludes that the integration of ethnoscience in PjBL learning can increase students' understanding and involvement, and encourage them to relate lesson material to the local cultural context.
