Abstract

Rice is one of the most important staple crops in Indonesia. Rice is the main source of food for the majority of Indonesia's population, including the Stabat area, which is a small town part of Langkat Regency, North Sumatra Province. Rice itself needs water to grow and develop, and is a plant that is no stranger to pests in the form of birds, mice, javelin, and so on. In dealing with pests, farmers in Stabat usually still use traditional methods by installing scarecrows and using pesticides to kill the pests. The work carried out by always going to the fields takes up a lot of energy and time from farmers. The University of North Sumatra Community Service Team offers a solution, namely making tools to protect rice plants from pests (javelin, aphids, caterpillars, mice, fungi) using pest detection sensors to help farmers in caring for rice to maintain the quality and quantity of rice through spraying pests to reduce losses incurred by farmers, especially during the harvest period. Solar energy-based pest control tool to improve the quality of rice plants to reduce losses. Farmers can also reduce the spraying of rice pests using chemicals so that soil fertility is maintained

Abstract

The contamination of wastewater by synthetic dyes such as Methyl Red poses serious environmental and health risks, necessitating effective remediation methods. This study investigates the synthesis and characterization of hybrid bionanocomposites composed of polycaprolactone (PCL), rice husk ash (RHA), and titanium dioxide (TiO2) nanoparticles for the efficient degradation of Methyl Red (MR) dye. The composites were prepared using a co-precipitation method for the incorporation of nano-RHA and TiO2. Characterization of the bionanocomposites was conducted through scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), and photodegradation tests. XRD analysis, using the Scherrer equation, revealed crystallite sizes ranging from 19.01 nm (composite S0) to 27.25 nm (composite S2). FTIR spectra showed characteristic absorption peaks corresponding to Ti–O (669.29 cm⁻¹), Si–O (970.19 cm⁻¹), and C–H (2960.73 cm⁻¹) bonds. The photodegradation results indicated a significant improvement in dye adsorption, with the highest degradation efficiency observed in composite S1, achieving 93.55% degradation after 45 hours of UV irradiation. The degradation efficiencies of S0, S1, and S2 were found to be 87.1%, 93.55%, and 25.81%, respectively, under the same conditions. The incorporation of TiO2 and RHA in PCL significantly enhanced its photocatalytic activity. This study demonstrates the potential of these bionanocomposites as sustainable materials for textile wastewater treatment
