Abstract

This study demonstrates various fuzzy-based strategies for classifying and diagnosing people with mental illnesses such as schizophrenia and bipolar disorder. The signals collected from 32 unipolar electrodes during non-invasive electroencephalogram analysis were examined to determine their key characteristics. This research uses a sophisticated fuzzy-based radial basis function neural network. Entropy analysis and analysis of variance of other statistical parameters are also used. Three hundred and twelve schizophrenic patients and 105 individuals with bipolar disorder were examined. In contrast to healthy controls, the data indicated that the patients were correctly classified. With close to 96% accuracy, the suggested method outperforms existing machine learning methods, such as support vector machines and k-nearest neighbors. Conclusion: This categorization method will enable the development of highly accurate algorithms to identify and classify various mental illnesses.

Abstract

The use of solar energy as a solar power plant (PLTS) has increasingly developed and received attention in the last few decades. BLK Sukabumi Regency has a building roof that has the potential to be used as a rooftop PLTS, so it can reduce electricity bills. This research aims to financially analyze the integration of rooftop solar PV at the Sukabumi Regency Job Training Center (BLK). In this research, planning and design of a rooftop PLTS with a capacity of 30.7 kW was carried out using Canadian Solar 320 W solar panels and an ICA Solar 30 kW inverter. The analysis results show that the construction of this rooftop PLTS requires initial investment costs of IDR 300,000,000.00 with annual operational costs reaching IDR 35,278,070.00 and total operational and maintenance costs for 20 years reaching IDR 558,453,870.40. Apart from that, this project has a Net Present Cost (NPC) value of IDR 894,907,600.00 with a payback period of approximately 12 years. After integration with Rooftop PLTS, electricity tariffs succeeded in decreasing by around 30% from IDR 900/kWh to IDR 630.64/ kWh, with a reduction in energy costs from IDR 63,370,935.00/year to 30,615,359.59/year. Based on the results of this research, the relevant suggestions are: implementing a 30 kW rooftop PLTS in BLK Sukabumi Regency as a step towards more sustainable use of renewable energy; conduct further feasibility studies to find alternative components such as solar panels or inverters that are more economical without sacrificing system performance; and consider utilizing renewable energy in other locations on a larger scale, such as government buildings or large industries, to reduce dependence on fossil energy sources.
