“…Based on the performance test, although the mini tiller with Honda EGX 2.0H was heavier than the scaled mini tiller with the standard engine, the operator felt it was lighter and easier to operate the mini tiller with Honda EGX 2.0H due to the lower mechanical vibration of the powertrain and the more responsive mini tiller. Previous studies also tested the electric mini tiller's lightness and ease of operation [17,18].…”

Mini tiller is one of the agricultural machineries used for a secondary soil tillage for narrow fields. In general, it is equipped with a 4-stroke gasoline engine. Internal combustion engine is considered as one of the contributors to carbon emissions in the world, so it is necessary to find alternative energy uses. One of the famous alternative energies is electricity. Nowadays, the utilization of electrification in human life is widespread, for example, for an electric vehicle. However, the implementation of electrification in the agricultural sector has not been extensively adopted. This research investigated the performance and energy consumption of a local brand mini tiller (Cakar Baja) coupled with a Honda electric powertrain. Results showed that applying an electric mini tiller on flat and dry land can smoothly plough the soil. Furthermore, the field capacity of this electric mini tiller showed 0.11 ha/h with an effective field capacity of 0.07 ha/h. During performance testing, it showed a field efficiency of 80%, which means low energy use costs. This electric mini tiller demonstrates the opportunity to use it as future agricultural machinery for a household with a small agricultural ground.

“…Las actividades que se realizan en este sector demandan una carga física muy alta, razón por la cual en los últimos años se ha aumentado la mecanización de la agricultura [3]. Sin embargo, la exposición a la maquinaria agrícola trae consigo otra serie de riesgos como las vibraciones de todo el cuerpo [4], así como el ruido [5], que si se llegan a convertir en excesivos pueden conducir a efectos crónicos y agudos en la salud [6].…”

Como parte de las actividades que se realizan en el sector agrícola se hace uso de vehículos, por lo que se tiene contacto con diferentes agentes físicos como el ruido y las vibraciones de cuerpo entero, debido a esto el objetivo de este proyecto fue determinar la exposición ocupacional a estos agentes durante el uso del tractor, específicamente en labores realizadas en la Zona Norte de Cartago, Costa Rica. Para alcanzar dicho objetivo, se efectuó un estudio exploratorio en 13 fincas, en las cuales se cuantificaron los valores de exposición a ambos agentes, haciendo uso de un vibrómetro y audiodosímetros. Como resultado, se obtuvo que los niveles de exposición diaria a vibraciones se encuentran sobre el valor de acción en el 53,8% de los casos, y los resultados del nivel sonoro continuo equivalente (NSCE) se ubican entre los 54,8dB(A) a 75,4 dB(A), por lo que no sobrepasan el nivel de exposición ocupacional. Además, se identificaron los factores de riesgo relacionados con estos agentes, la antigüedad de la maquinaria y dispositivos colocados en el vehículo, así como los factores personales que pueden influir en la aparición de dolencias, relacionadas con la actividad laboral. Existen otros factores de riesgo en la población en estudio, asociados a las posturas adoptadas y al índice de masa corporal de los colaboradores. Se concluye que la exposición a las vibraciones en cuerpo entero, podría llegar a generar efectos a la salud a largo plazo, además, el dispositivo de acople y modelo se convierten en factores que pueden influir en la exposición.

The mechanization of agricultural operations greatly influences both the efficiency of farming operations and the health and safety of farm workers. Human exposure to working environments represents a significant hazard associated with machines and the environment. This research focuses on evaluating the ergonomic aspects of the newly developed artificial intelligence (AI)‐based cotton fertilizer applicator, aiming to assess the potential impact on workers' health, safety, and overall exertion. Ergonomic factors such as heart rate (HR), oxygen consumption rate (OCR), energy expenditure rate (EER), physiological work cost, as well as discomfort and posture during use, were assessed at three different operating speeds of the applicator. Results showed that HRs, OCR, and EER ranged from 86 to 109 beats/min, 0.44 to 0.83 L/min, and 9.3 to 17.45 kJ/min, respectively, indicating that the physical demands on workers were within manageable limits. Discomfort was predominantly noted in the palms, attributed to the necessity of controlling the applicator with both hands. Analysis of cardiac effort revealed that 93.75%, 92.70%, and 94.67% of effort was expended during work at speeds of 0.5, 0.8, and 1 km/h, respectively, with the remainder during recovery periods. The workload on the middle deltoid muscle during field operation varied between 10.15%–14.58% for left‐hand controls and 1.85%–3.5% for right‐hand controls. Statistical analysis highlighted significant differences in physiological responses among participants, with ergonomic parameters closely linked to the applicator's forward speed. The study concludes using the developed AI‐based cotton fertilizer applicator does not pose significant health risks to operators, suggesting its ergonomic design effectively mitigates physical strain.
