The low productivity of sugarcane in various regions, especially in production centers, has caused domestic sugar production to fluctuate and unable to meet national sugar needs. That is thought to be due to the inefficient use of inputs by sugarcane farmers, lack of access to capital and information, resulting in farmers being unable to provide the latest technology for sugarcane cultivation. The research objective was to analyze the performance of the sugar cane business in Malang Regency by measuring its technical analysis using the Data Envelopment Analysis (DEA) approach. This research was conducted using a survey method of 50 respondent sugarcane farmers in Malang Regency with the multistage random sampling method. The average total technical efficiency (TE CRS) of sugarcane farmers in Malang Regency is 0.766, the average value of pure technical assessment (TE VRS) is 0.829, and the average efficiency scale is 0.926. Farmers who are technically efficient at optimal scale (CRS) of 18% and 82% are not yet at optimal scale. Farmers who are not at an optimal scale are in an IRS condition of 50% and DRS condition of 32%. The result of correlation analysis shows that land areas as a control variable significantly affect the relationship between technical analysis and income, which shows a solid and positive value is 0.415.

Objective to study the adherence to the principles of rational nutrition by representatives of various professional groups living in the Russian Federation and the Republic of Tajikistan. Material and methods.The study was conducted using a questionnaire-survey method among 543 mental workers of the Samara region and 158 students of the Avicenna Tajik State Medical University (Republic of Tajikistan), followed by statistical processing of the data. Results.Violations of the principles of rational nutrition are commonin various professional groups of the working-age population, including among students of a medical university. According to anthropometric studies, 61% of the surveyed workers were overweight and obese; in the group of students this indicator was only 8%, 29% of students were underweight. Violations of nutrition regimen were found among 31.1% of employees and 38% of students. Factor analysis of the actual nutrition of workers revealed 5 types of nutrition models characterized by a stereotype of eating behavior due to the consumption of certain foods and beverage. The regression analysis confirmed the relationship between the risk of obesity and adherence to types 2, 4 and 5 of nutritional models; an individual's adherence to nutritional model type 3 reduced this risk. In the group of the surveyed, the deterioration of the diet quality was revealed due to the excessive consumption of high-calorie foods, "fast food", sweet carbonated drinks, as well as insufficient consumption of vegetables, fruits, fish. The correlation analysis established the relationship between the body mass index and complaints presented by the survey participants concerning the cardiovascular, digestive, endocrine and musculoskeletal systems. The study identified the most common alimentary-dependent pathologies among students such as gastritis, chronic pancreatitis, and chronic cholecystitis. Conclusion.The revealed violations of the principles of rational nutrition, the nutritional status, form the risks of development of the gastrointestinal tract diseases, metabolic disorders and cardiovascular pathology. The results obtained indicate the need of preventive measures in relation to the adherence to the principles of rational nutrition, creating awareness in various professional groups of the population, including students of medical universities in different states.
