Weeding activities in rice cultivation are manual labor that requires bending, squatting, and stooping for relatively long periods of time and is performed repetitively. These conditions can cause musculoskeletal disorders (MSDs) in farmers. This study aims to identify the location and level of musculoskeletal complaints in weeders using the Nordic Body Map (NBM) instrument. The study design uses a quantitative descriptive approach with a cross-sectional method. The study respondents were active rice farmers who weeded manually and were selected through purposive sampling based on inclusion cr

The process was developed through three main stages: cellulose extraction, conversion of cellulose to sorbitol using MnLaFeO₃ photonanocatalytic, and conversion of sorbitol to iodohexane using two types of reactants—HI and a combination of NaI, H₂SO₄, HCOOH, and ethanol. The main control variables in the sorbitol conversion process are the type of reactant, reaction temperature, and reaction time. The experimental results showed that the use of a combination of NaI, H₂

This study develops and optimizes a MnZnFe₂O₄ photonanocatalytic process under UV irradiation to convert cellulose into sorbitol. Three key process variables—catalyst mass (0.5–1.0 g), UV energy (60–125 J/s), and exposure time (30–60 min)—were evaluated and optimized using Response Surface Methodology, Genetic Algorithm, and Particle Swarm Optimization. The optimum operating conditions were achieved at 1.0

Therefore, the development of low-cost, efficient technologies is required to provide a safe, pollution-free water environment. The attapulgite surface was used in this study because it has a good absorbent surface for removing bromocresol purple dye from its aqueous solutions. Because attapulgite has a high absorption capacity, it can be used to remove pollutants in both its normal and modified states. Factors affecting adsorption were studied, such as the
Read MoreGroundwater quality in some villages of Thoubal and Kakching districts, Manipur, India, were assessed to check viability for irrigation during the 2024 pre-monsoon season. Twenty groundwater samples were examined for physicochemical parameters, including total alkalinity (TA), electrical conductivity (EC), total hardness (TH), major cations Ca2+, Mg2+, Na+, K+, Cl- and anions SO42-, CO32- and HCO3-. Parameters assessed included Residual Sodium Carbonate (RSC), Percent Sodium (%Na+), Sodium Adsorption Ratio (SAR), Magnesium Hazard (MH), Kelly’s Ratio (KR), Permeability Indices (PI), Potential
