Abstract

This study examines the performance comparison of silicon and perovskite as semiconductor materials in photovoltaic solar cell technology. Silicon is known for its long-term stability, consistent power conversion efficiency, and well-established manufacturing infrastructure. However, its high-temperature, energy-intensive production process raises concerns about cost and environmental impact. In contrast, perovskite offers high power conversion efficiency, tunable material structure, and low-temperature fabrication, but faces major challenges in environmental stability and lead-related toxicity. A literature-based approach was applied, analyzing experimental and simulation data to evaluate key parameters such as energy bandgap, efficiency, carrier mobility, and thermal durability. The analysis indicates that combining both materials in tandem configurations presents a promising strategy for developing more efficient, flexible, and environmentally friendly photovoltaic systems

Abstract

The fermentation process of tempe embus with conventional methods is highly dependent on weather conditions and requires heat energy (temperature) 25°C - 35°C within 36 - 48 hours. This research aims to stabilize the heat energy and reduce the fermentation process time to get quality tempeh production results in a short time. The research method used is the experimental method by making an automatic temperature and humidity controller and testing its performance. This tool works using the DHT22 sensor and ESP32 microcontroller as the control center. Temperature automation is done with two conditions that are used to regulate lights and fans. If the fermentation temperature is lower than the setpoint, the lower light and upper light turn on, if the temperature rises, the upper light turns off and the fan turns on, to keep the temperature within the pre-set setpoint value. This research shows that the temperature and humidity control device operates stably in the temperature range of 32°C to 35°C. At these temperature conditions, the fermentation process runs stably. At that temperature condition, the fermentation process of tempe embus lasts 16 hours, with testing of color, taste, and smell for the best quality category Tempe.

Abstract

Electrical insulators are vital components in power transmission and distribution systems. The performance of insulators is significantly influenced by environmental conditions, including humidity, pollution, and temperature, as well as their material composition. This study reviews several recent scientific publications related to the performance of ceramic, polymer, and composite insulators under various environmental conditions. The analysis indicates that environmental contamination significantly reduces insulator performance, whereas industrial and agricultural waste-based materials, such as rice husk ash (RHA) and fly ash, offer considerable potential as innovative, environmentally friendly solutions. Experimental and simulation methods play a crucial role in understanding the electrical characteristics of insulators.
