Nowadays there is incompatibility with moral ethics and Pancasila values through the media. The emergence of bad behavior such as violence in the name of religion, bullying at school and outside school, student brawls, sexual harassment between school friends, theft, and bullying in the media, can become role models for children's behavior if not dealt with immediately. This study aims to analyze the effect of scientific learning based on Tri Hita Karana on the profile of Pancasila early childhood students. This study uses the experimental design for 50 early childhood children (5-6 years). Data was collected using observation guidelines that had been tested for content validity to observe the children's participation. The score data obtained for each variable was transformed to a scale of 100. The data in the form of percentages were analyzed for the normality of the data distribution and declared normal, and the linearity analysis of the regression line was declared linear. Hypothesis testing data analysis techniques apply simple regression and multiple regression. The error level used is 0.05. It was found that scientific learning based on Paluhuran, Pawongan, and Palemahan positively affected the profile of Pancasila students. Taken together, scientific learning based on Tri Hita Karana positively affects the profile of Pancasila early childhood students. It is hoped that all parties involved in the project to strengthen the profile of Pancasila early childhood students will apply scientific learning based on Paluhuran, Pawongan, and Palemahan holistically and integratively.

Electrical energy is a very complex problem for every country in the world, as well as in Indonesia in particular, with the rapid progress of the country’s industry, of course, followed by an increase in the generation of electrical energy. While the current energy generation most often comes from fossil fuels, which are increasingly depleting, the energy supply will decrease and increase sales. Therefore, every country is competing to find other energy for electrical energy generation. Renewable energy is a green energy generator whose supply is abundant and inexhaustible. Solar power plants (PLTS) are one of the green energies developed by the Indonesian government to utilize energy derived from non-fossil fuels. To support this, it is necessary to study and research to be done using the DC-DC up/down converter is expected to obtain results that can be used as a reference in the development of solar power plants (PLTS). With a DC-DC up/down converter, the voltage stabilization produced by PLTS can be stabilized by a DC-DC converter from 9 volts DC to 11.5 volts for a minimum voltage. Above 12 volts to 18 volts, up to 12 volts can be stabilized.

Abstract Boring learning is one of the causes of low student motivation. PAIKEM as a learning model is a solution to overcome these problems. This study aims to find the influence between the application of the PAIKEM model on students' learning motivation in the subject of Hindu Religious Education and Ethics at SMPN 1 Mataram This research was conducted with an Associative Quantitative approach and Ex-Post Facto method. Research data were obtained through questionnaires, observations, and documentation. Data analysis assisted by SPSS 25.0 was carried out to conduct descriptive analysis and inferential analysis which included prerequisite tests, simple regression analysis, and hypothesis testing. The study population was all Hindu students at SMPN 1 Mataram totaling 381 people. The sample used was class VIII of 137 students. The results of data analysis: the mean (average) value for the application of the PAIKEM model is 84.01 with data distribution showing that 41 students (30.37%) stated very well, 81 students (60%) stated well, and 13 students (9.63%) stated quite well. While the results of the analysis of the mean value of student learning motivation are 82.89 with data distribution showing that there are 46 students (34.07%) stating very good, 62 students (45.93%) stating good, and 27 students (20%) stating quite good. Through simple regression analysis, it was found that variables X and Y had a relationship of 33%. Based on the results of the product moment correlation test, the pearson corelation value is 0.579 with the results of Df (degrees of freedom) = n-2 or 135-2 = 133. At the 0.05 significance level, the r table value is 0.169. This means that rcount = 0.579> rtable = 0.169. So it can be concluded that Ho is rejected and Ha is accepted. From the results of this study it can be recommended to teachers to apply PAIKEM in learning. Keywords: PAIKEM Model, Learning Motivation, Students
