The historical method was used in the context of compiling this research because the temporal as the main discussion began in 1900 and ended in 1998. The researcher also focuses more on the environmental history approach so that this research can be used as criticism and suggestions for future policy makers. Developments designed by the authorities during the period 1900 to 1998 have sacrificed ecologically valuable assets, namely forests. The government's interest in the economic sector is believed to be the main factor in the loss of forest land in Surakarta. The city of Surakarta experienced modernization during the colonial period so that mobility in urban areas has increased. The government that has the power in development must open up new production areas to meet needs instead of economic interests. Even the autonomous rulers experienced changes in culture and traditions regarding forests because forest land was getting narrower. Forest degradation continued during the New Order era. The period of Suharto's rule made forest land in Surakarta increasingly invisible. The role of the first lady who is the son of the Surakarta area is the main factor at this time. Urban development has increased sharply with the provision of public facilities and infrastructure.

Rational use of fodder resources involves finding and introducing non-traditional types of fodder into the diet of animals. For a long time in animal husbandry, productivity stimulants have been used, which promote the process of conversion of feed nutrients into products and affect its quality.

Many years of research have shown that increasing the efficiency of bioconversion of feed nutrients into rabbit products depends on the type of diet, level, and completeness of feeding. A promising reserve for the production of rabbit products under such conditions is the use in the diets of new generation feeds that have immunomodulatory, anti-infective and other effects.

Probiotic is a biologically active supplement based on bacterial strains. Probiotics include typical representatives of the normal microflora of the large intestine of animals: bifidobacteria, lactic acid bacteria, streptococci. Probiotics are aimed at the competitive exclusion of opportunistic bacteria from the list of intestinal microflora, which distinguishes them from antibiotics.

The experiment involved a population of rabbits of meat and skin productivity. Two groups of young rabbits (females) control and experimental (4 heads each) were formed.

The basic diet for these groups was the same and consisted of compound feed PC 90 Lux, manufactured by KreMix LLC. The difference in feeding between groups of rabbits was the additional introduction to the main diet of rabbits of the experimental group of probiotics "Enteronormin Detox" produced by LLC "Agricultural Enterprise" Microbiological Systems at the rate of 0.5 g per 1 kg (according to the manufacturer's recommendations). The probiotic contained the bacteria Enterococcus spp. 1–5 × 107 CFU / g, Bacillus subtilis spp. 1–5 × 106 CFU / g, Lactobacillus spp. 1–5 × 106 CFU / g, chitosan, yeast autolysate, ground mustard, ground garlic, ground cinnamon, zeolite. Preliminary assessment of the chemical composition and quality of feed.

The use of the probiotic has improved the resistance of animals and increased preservation during the rearing period and has had a positive effect on the growing intensity and meat productivity of rabbits.

In the context of a constantly growing shortage of bedding materials, the practice of their repeated use after regeneration is becoming more widespread. However, the known methods of litter regeneration, such as biothermal composting in piles without covering or with covering the piles, have certain disadvantages and require improvement in the direction of intensifying biothermal processes and increasing the level of disinfection. Also, these methods relate mainly to the bedding of broiler chickens. The main kinetic regularities of the processes of regeneration of the used litter of other bird species have been insufficiently studied. Considering the above, the goal of our research was to develop an improved method for regenerating used turkey litter and to study its effect in comparison with known methods on the kinetics of the biothermal treatment process, chemical composition and microbial contamination of the litter. An improved method of regeneration was developed, which involved adding a special microbiological preparation to the bedding and irradiating the surface of the pile during composting with ultraviolet radiation (UVR). For comparison, the known methods of litter regeneration were used: 1K – by composting in a pile; 2K – the same and, in addition, covered the litter during composting with foil. As shown by the research results, the addition of a microbiological preparation and covering the shoulder with a film contributed to an increase in the temperature of the litter during the biothermal treatment by 1.2 – 9.4 °C (p <0.05). The addition of a microbiological preparation and irradiation of the surface of the pile with UV radiation made it possible to reduce the emission of ammonia from the litter during its regeneration by 4 – 25 mg/m2 per hour. compared with the first control option (P <0.01), while when the collar was covered with a film, it increased. The highest nitrogen content after biothermal treatment was noted in the litter, the regeneration of which was carried out in accordance with the improved method, and the lowest in the variant where the pile was covered with a film. After biothermal treatment, microbial contamination of the litter with enterobacteria inside the piles decreased in all variants: in the first control by 90 %, when the pile was covered with a film by 93 %, with the addition of a microbiological preparation and irradiation of the pile with ultraviolet radiation (improved method) by 95 %. Covering with a film, and especially irradiation of the pile with ultraviolet radiation, made it possible to significantly reduce microbial contamination of the litter and on the surface of the piles. Microbial contamination of the litter by fungal microorganisms after regeneration decreased 2.5 times – on the surface of the piles, and 5 times – inside.

In the article, the main physical and chemical properties of various samples of diesel fuel are investigated and their influence on low-temperature characteristics is evaluated. The regularities of changes in the low-temperature properties of the fuel depending on the hydrocarbon composition, as well as its effect on the injectivity of the fuelto depressant additives, have been studied. Based on the results obtained, it was concluded that the low-temperature properties of diesel fractions are best correlated with such physicochemical properties as: the latitude of the fractional composition, the boiling point of 90% and the molecular weight of the fraction. Of the presented hydrocarbonsin the composition of diesel fractions, the content of paraffins, their normality factor and the ratio of naphthenes to n-paraffins have the greatest influence. At the same time, the determining factors affecting the injectivityof diesel fractions to a pour point depressant are: the content of paraffins and aromatics, the molecular weight distribution of n-paraffins, and the width of the fractional composition.

Alternative methods and technologies for desulfurization of petroleum products in order to achieve compliance with marketable products are considered. The possibility of widespread use of unconventional desulfurization methodsallowing deep desulfurization of oil fractions is shown. A promising way to reduce the total sulfur contentin commercial petroleum products may be the combination of unconventional post-treatment methods with traditional hydrocatalytic processes. Unconventional methods, in particular wave desulfurization methods, should also be used to prepare oil for further processing at atmospheric and vacuum distillation plants.
