Abstract

The need for new renewable energy sources is growing because of several problems, such as high electricity costs, frequent power outages, and dependency on fossil fuels. It's critical to come up with solutions to this problem, like using solar power. Nonetheless, to guarantee a steady supply of energy, solar panels must be well controlled. The primary goal of this study was to create a system that would use an ATmega328 microcontroller, a logger module, and an INA219 voltage sensor, along with a BH1750 light intensity sensor, to detect the voltage and intensity of light on solar panels in real time. The study technique includes the steps of system definition, design, and development using a 4D approach that has been streamlined into 3D. The system's ability to make precise measurements and store data in a readily accessible and processable manner was demonstrated by the test results. Real-time solar panel state monitoring is made possible by the system's primary ATmega328 microprocessor, and data storage in CSV format enables easy analysis. In summary, this system was success for tracking and improving energy efficiency

Abstract

The persistence of pesticide residues such as cypermethrin in water bodies has raised environmental concerns, necessitating the development of effective photocatalytic materials for their degradation. This study examines the influence of solvent-assisted magnetite synthesis on the structural, magnetic, and photocatalytic properties of Fe₃O₄/TiO₂ composites for cypermethrin degradation under UV light with a focus on a comparative approach between alkaline and acidic synthesis routes, which has not been extensively reported. Fe₃O₄ was synthesized via co-precipitation using NaOH and HCl to assess the impact of solvent conditions. X-ray diffraction confirmed the spinel-phase structure in both samples, while SEM showed finer and more uniform particles in the NaOH-derived sample. VSM analysis revealed that Fe₃O₄–HCl exhibited higher saturation magnetization (Ms = 57.98 emu/g) but lower coercivity (Hc = 0.0206 T) than Fe₃O₄–NaOH (Ms = 41.26 emu/g; Hc = 0.0241 T), indicating synthesis-dependent magnetic properties. UV–Vis analysis identified a cypermethrin absorption peak at 220 nm, which was used to monitor degradation. The Fe₃O₄–NaOH:TiO₂ composite showed superior photocatalytic activity (31.98% degradation in 90 minutes) compared to Fe₃O₄–HCl:TiO₂ (22.86%). Kinetic modeling using the pseudo-first-order equation yielded a higher rate constant for Fe₃O₄–NaOH:TiO₂ (k = 0.00172 min⁻¹; R² = 0.769), while Fe₃O₄–HCl:TiO₂ showed slower kinetics but better linearity (k = 0.00030 min⁻¹; R² = 0.9999). These results suggest that alkaline synthesis enhances particle morphology and charge transfer efficiency, improving photocatalytic performance. Therefore, Fe₃O₄–NaOH:TiO₂ represents a promising candidate for cypermethrin remediation in wastewater treatment.

Abstract. A house as a shelter for the occupants requires ventilation, both natural and artificial, to achieve thermal comfort. Openings allow air to circulate in and out of the building, thus affecting the humidity and temperature of the building. The research was located in the Type 36 Mutiara Baet Residence housing complex, in Baet Village, Baitussalam District, Aceh Besar Regency. The case study is a house facing west, east, north, and south which has openings without direct sunlight. Using a mixed method research method, which combines qualitative and quantitative models. Qualitative methods are carried out using documentation, interviews, and observation. while the quantitative method is carried out through measurements of humidity, wind speed, and temperature. Interview results showed that 70% of building occupants said that the residence they lived in felt hot so it was uncomfortable to be indoors without mechanical cooling, while the existing openings could not be maximized for natural ventilation as intended. The remaining 30% of respondents thought that openings could help reduce heat. The results of thermal measurements, the average temperature in the living room was 30.93°C, while the average temperature in the kitchen room was 30.99°C. The results of measuring the average humidity (RH%) in the living room was 46.40% and the average humidity (RH%) in the kitchen room was 46.18%. Only 20% of residential living rooms and kitchens in Mutiara Baet Residence have wind circulation, while in the other 80% of residences, the detected wind speed is 0.0 m/s, which means there is no wind movement/circulation
