For these, an affordable and sustainable alternative could be that of using double-grip processors.

Operating at high efficiency is one of the prerequisites of sustainable forest operations.

However, reasons such as limited business opportunities during the year may negatively affect the machine utilization rate. Coupled with high ownership costs, this results in economic sustainability problems. With this in mind, some practitioners have started to replace the traditional bucking operations conducted motor-manually at the landing with full mechanization using harvesters. T

Abstract:

Despite the increasing presence of modern mechanization, tree felling and timber processing using chainsaws still dominate forestry operations in Serbia, accounting for approximately 90% of the total harvested timber. This highlights the need for a more in-depth analysis of the ergonomic aspects of such work methods. The aim of this study was to assess the physical workload of chainsaw operators engaged in tree felling and logging processing in selection forests of beech and fir, using the OWAS method and the Lundqvist index, as well as to provide recommendations for improving these work pract

Abstract:

Bumblebees play a vital role in pollination of plants due to their large size and hairiness hence are ideal for picking up and transferring pollen. They can vibrate (‘buzz’) flowers and have no communication system but can work efficiently in tunnels as they have a better sense of direction. They are 400 times more efficient than honeybees at any pollination chore and are capable of visiting 30 to 50 flowers per minute. They are non-swarming and less aggressive than honeybees. Bumblebee generally forages during the early morning (0530-0800h) and evening (1700-1900h) time. Bumblebees are better

Abstract. Modern bioenergy crops have potential to play a crucial role in the global energy mix, especially under policies to reduce carbon dioxide emissions. The management of short-rotation willow crops involves several operations that deliver biomass for different uses. In commercial-scale operations, high-performance, mostly automated equipment is frequently used; however, in small-scale operations, smallholder farmers adapt traditional agricultural equipment to fit their needs. This study evaluated the field performance of planting and cutback operations in small-scale willow crops using

On the basis of the proposed geoenergy approach, the energy efficiency of forestry and ecosystems of the Transnistrian Moldavian Republic in a single energy unit – joules has been studied. Relevance of the study is explained by the fact that the energy crisis in the 1970s has dramatically increased interest in the problem of energy consumption and energy saving. Despite the calls and practice of energy saving over a hundred years, the specific energy costs increased by 8-10 times. All these data indicate the need to introduce energy-efficient technologies of environmental management in all sph

AbstractEfficient forest operations are essential for forest enterprises, who provide wood and numerous ecosystem services for the society. Important factors influencing the efficiency of forest operations, and thus the harvesting costs, are the level of mechanization, the harvesting method applied, the forest road network, and the training of the labourers. The cost of labour, i.e. salaries, is another important driver of harvesting costs. However, its effect on and relative importance for overall harvesting costs is poorly described in the scientific literature. Thus, this study aims to anal

Abstract:

Mechanization of forestry work is crucial in forest management, and the specific nature of the tasks performed requires reliable machines with a high level of technical readiness. Therefore, models describing the exploitation process of multi-operational machines used to obtain wood raw materials, and especially assessing the level of their technical readiness, are extremely important. For multi-tasking objects performing random activities in given time intervals, calculating readiness measures is a complex issue.

Abstract:

Globally, the demand for wood as a raw material, but also for non-wood forest products, is growing year by year. Therefore, the question arises how to sustainably use forest resources, taking into account on the one hand the constant needs of society, and on the other the existence of a sustainable ecosystem. There are many practical steps that forest management companies need to take to protect forests, while at the same time making adequate profits from the production and sale of both wood and non-wood forest products. So, theoretically, sustainable use of forests means such felling of trees

In response to the growing demand for automation and labor-saving solutions in agriculture, there has been a noticeable lack of advancements in mechanization and robotics specifically tailored for fruit cultivation. To address this gap, this work introduces a novel method for fruit recognition and automating the harvesting process using robotic arms. This work employs a highly efficient and accurate model utilizing a single shot multibox detector (SSD) for detecting the precise fruit position. Once the fruit's position is identified, the angles of the robot arm's joints are calculated using in
