Because solar energy has so many benefits all year round, it can be a cost-effective energy source when used, especially since it is so abundant globally. to produce electricity by converting sun energy. The equator-based nation of Indonesia boasts an abundance of solar energy resources, with an average daily solar radiation intensity of about 4.8 kwh/m2. However, there is an abundance of solar-based energy sources that can be utilized. Especially in Lolo Wano Village, where the intensity of solar radiation is quite high, it is an option to develop a Solar Power Plant (PLTS) as a solution to electrical energy needs. In order to specifically identify the class of unknown object labels, classification techniques are employed since they are able to identify models that distinguish between different data classes or data ideas. In the meantime, the Naïve Bayes algorithm takes into account multiple factors that will influence a decision's final result in order to forecast future opportunities based on data that has already been collected. The information utilized comes from observations made by the LOLO WANO VILLAGE PLTS Community (PLTS). The data gathered from the satisfaction survey will be divided into two categories: training data and testing data. The testing data's accuracy will be evaluated using the output of the training data model. The classification findings demonstrate that, with the maximum level of accuracy at 87.50%, the Naïve Bayes algorithm is appropriate for gauging student satisfaction with online learning.

The quality of welfare is an important indicator in assessing the social and economic development of a region, including in East Java, which has the second largest population in Indonesia. This study aims to analyze the factors that influence the quality of welfare in East Java in 2023, focusing on variables such as average food and non-food expenditure, the number of poor people, average years of schooling, life expectancy, and open unemployment rate. Data from the Central Bureau of Statistics shows that the percentage of poor people reached 10.35% and the open unemployment rate was 4.33%. The factor analysis method was used to identify the relationship between these variables and ensure the assumption of multivariate normality before the analysis was conducted. The results of the data characteristics analysis showed that all quality of life factors had asymmetrical distributions, with medians that were not centered, and outliers in the food and non-food expenditure data. Testing the assumptions of factor analysis indicated that the data met the requirements of multivariate normal distribution, dependence, and adequacy for further analysis. From the factor analysis, two new significant components were found, namely social and economic education and population and education. These findings provide important insights into the main dimensions affecting people's welfare in East Java, which can form the basis for the development of more effective socioeconomic policies.
