    Grain harvesting combiners’ use in Poltava region. Analysis and forecasts
    (Полтавський державний аграрний університет, 2024) Padalka, V. V.; Burlaka, O. A.; Kelemesh, A. O.; Rozhko, I. I.; Падалка, Вячеслав Вікторович; Бурлака, Олексій Анатолійович; Келемеш, Антон Олександрович; Рожко, Ілона Іванівна
    The study aims to find technical, organizational, and economic mechanisms for improving the efficiency of grain harvesters by the example of the resource potential of agricultural harvesting equipment in the Poltava region. The study relied on statistical data, including both quantitative and qualitative characteristics of grain harvesters. The information was gathered from agricultural producers in the Poltava region, regardless of the form of ownership. The data was collected through automated records kept by the agricultural machinery registration department of the State Production and Consumer Service in Poltava. The information pertains to the end of the year 2023. The following indicators and characteristics have been studied in detail: the total number of combine harvesters registered in the Poltava region and their average age since the date of manufacture; absolute quantitative indicators regarding the duration of use of grain harvesters according to agricultural machinery manufacturers as of 2023; and relative indicators regarding the duration of use of grain harvesters according to agricultural machinery manufacturers as of 2023. After conducting the statistical analysis, it was found that machines from certain manufacturers have been used for over ten years in higher percentages: John Deere (66,23 %), Fortschritt (68,75 %), Claas (72,32 %), Case (81,42 %), combine harvesters manufactured in Ukraine and post-Soviet countries (88,60 %), Volvo (91,67 %), Massey Ferguson (94,12%), Sampo (100 %), New Holland (28.1 %). In the specified category "combines older than 10 years prevail", the most commonly used combiners in the Poltava region are John Deere, Claas, Case combiners, and ones manufactured in Ukraine and post-Soviet countries. This makes up the majority of the combiner park in Poltava Region under current conditions. The national economy is currently facing the challenge of efficiently and effectively assessing the technical condition of grain harvesters, whether old or new. This has become an urgent issue that requires immediate attention. It is crucial to pay special attention to the quality of repair work done on the various units and components of these machines, ensuring that all necessary spare parts and accessories are provided.

    Waste usage as secondary resources
    (Procedia Environmental Science, Engineering and Management (P - ESEM), 2020-10) Gorbenko, O. V. ; Lyashenko, S. V. ; Kelemesh, A. O. ; Padalka, V. V. ; Kalinichenko, A.

    The current state of waste management in Poltava region is summarized in this article. In this article were determined places of accumulation and the influence of population size on the volumes of domestic solid wastes formation. Here also was analyzed dynamics of changes in the production of domestic solid wastes in rural areas and in cities. The morphological composition of domestic solid wastes was determined due to researches during 2017-2019. In the article was conducted comparative analysis of the data of changes in the percentage of components, which are part of domestic solid wastes depending on the time of year. It is determined that about 55% of the waste is the organic part of domestic solid wastes. Using certain technologies organic part of domestic solid wastes can be processed into valuable products. The technology of processing the organic component of domestic solid wastes into compost adapted to conditions of private farm households is offered in this article. Here are justified the design parameters of small-sized household chopper for compost production and are given technical conditions of machine usage the in conditions of private farm households. Here also was calculated economic feasibility of machine usage for three farm households for the purpose of processing the organic component of domestic solid wastes into compost. The costs for equipment, materials and inventory were about 2.835 thousand EUR. Costs for electricity, water, wages, etc. were 4.379 thousand EUR. The cost of production of one kilogram of compost was 0.093 EUR/kg. The payback period of the project is 9 months. The use of new developed equipment for the processing of organic component of domestic solid wastes makes it possible to reduce the ecological environmental impact to a considerable extent. In addition, the use of wastes as secondary resources makes it possible to obtain funds for private farm households.
