The state of agricultural digitalisation in HungaryReview

Dániel Fróna

Res. Agr. Eng., 2024, 70(1):1-12 | DOI: 10.17221/15/2023-RAE  

In recent years, the concept of digitalization has gained increasing attention in the field of agriculture. The adoption of digital technologies such as sensors, drones, and precision farming tools has the potential to revolutionize how agricultural production is carried out, leading to increased efficiency, productivity, and sustainability. This study examines the current state of digitisation and the use of digital tools in agriculture among Hungarian farmers. The uptake of digitalisation has been slow, and more comprehensive policies and strategies are needed to improve progress. The study shows that while there are positive developments, such as...

Enhancing melon yield through a low-cost drip irrigation control system with time and soil sensorOriginal Paper

Thawatchai Thongleam, Kriengkrai Meethaworn, Sanya Kuankid

Res. Agr. Eng., 2024, 70(1):13-22 | DOI: 10.17221/20/2023-RAE  

Drip irrigation is a highly efficient method for watering crops, as  it delivers water directly to the roots and minimises wastage due to evaporation or runoff. This paper presents the development and implementation of  a low-cost drip irrigation control system that uses both time- and soil sensor-based approaches. The system’s efficiency was compared through a field experiment of melon growing, divided into three categories and four replications using a completely randomised design. The treatments include: T1 [time-based irrigation (TBI)], T2 [soil moisture-based irrigation (SMI)], and T3 [hand watering irrigation system...

Fabrication and performance test of a multipurpose ohmic heating apparatus with a real-time data logging system based on low-cost sensorsOriginal Paper

Diang Sagita, Dadang Dayat Hidayat, Doddy Andy Darmajana, Ari Rahayuningtyas, Hari Hariadi

Res. Agr. Eng., 2024, 70(1):23-34 | DOI: 10.17221/21/2023-RAE  

Ohmic heating is an emerging technology currently in high demand for application in various processes. In this research, a prototype of a multipurpose ohmic heating apparatus was successfully designed, fabricated, and tested. This apparatus was designed based on low-cost and versatile sensors and components available worldwide. Three independent chambers could be operated parallelly and individually with different treatments. Parameter data, i.e., voltage, electrical current, the temperature of heated material and environmental humidity-temperature, could be recorded by an embedded data logging system. The sensor had been tested and validated by comparing...

Energy and carbon dioxide emission analysis of a batch-mode paddy drying process in a rotary dryerOriginal Paper

Dewi Qurrota A’yuni, Dede Kurniawan, Muhammad Pradhipta Irwanda Prayoga, Andri Cahyo Kumoro, Mohamad Djaeni, Agus Subagio

Res. Agr. Eng., 2024, 70(1):35-42 | DOI: 10.17221/32/2023-RAE  

The rice drying process in a rotary dryer gives the benefit of producing uniformly dried rice in a short drying time. This work investigated a rotary dryer's efficiency and heat consumption at various temperatures (40, 50, and 60 °C) and capacities (10, 20, 30, and 40 kg). When loaded with 10 to 30 kg of rough rice and operated at 60 °C, the dryer produced dry rice with 14% w.b. moisture content for less than 3 hours. The energy efficiency and consumption were evaluated based on the experiment and theoretical analysis. According to the observation, a high temperature significantly shortened drying time. Thus, the total energy...

Comparison of experimental and numerical results on flow uniformity of seeds transmitted from the studded feed rollerOriginal Paper

Mustafa Gokalp Boydas

Res. Agr. Eng., 2024, 70(1):43-52 | DOI: 10.17221/34/2023-RAE  

Studded feed rollers are widely used in seed metering units of seed drills. The flow evenness is an important indicator of the performance of studded feed rollers. With this research, the effects of studded feed rollers with different stud numbers (27, 36, and 45 studs) on flow evenness were investigated both in the laboratory and by simulation in case of using different ground speeds (1.5, 2, and 2.5 m·s–1). While the experiments were carried out on the seed drill model prepared in the laboratory, the simulation was done with the Rocky DEM software program. In the laboratory and simulation studies, it was determined that...

Reconstructed military machine for unique field testing of agricultural machinery capabilitiesOriginal Paper

Detailed performance testing of agricultural machinery is very important in determining its value in use. These measurements cannot be limited to laboratory tests, such as braking the power take-off (PTO) shaft of  a tractor or performing dynamic tests of implements in a soil bin. Field tests are the ultimate way to test the capabilities of agricultural machinery. However, during such field tests, there are many parameters that can interfere with and affect the test results, such as inhomogeneity of the soil and tyre characteristics. In order to minimise these effects as much as possible, Hungarian University of Agriculture and Life Sciences (MATE)...
