Abstract The objective of this work was to evaluate the influence of the use of UV-C radiation at an intensity of 0.53 KJ m-2, during strawberry (Fragaria x ananassa) cultivation, on the physicochemical and phytochemical parameters of the fruits. The used experimental design was completely randomized, in a single-factor arrangement with 11, 19, 29, and 39 UV-C applications and without UV-C application. The hue of the fruits was smaller at the end of the study period. pH varied in strawberries that received 39 applications of UV-C, and the soluble solids content differed with 19 applications. Antioxidant activity was lower in fruits with 11, 19, and 29 UV-C applications, whereas vitamin C content was lower only in fruits that received 29 applications. The use of UV-C radiation at an intensity of 0.53 KJ m-2, during strawberry cultivation, affects the physicochemical and phytochemical parameters of the fruits, but does not cause losses in their quality.

Maize is an important commodity in Indonesia and is vulnerable to maize weevil (Sitophilus zeamais) during storage which can cause a 100% yield loss. Chasew Nut Shell Liquid (CNSL) is a botanical pesticide able to control S. zeamais. Increasing CNSL efficiency and effectiveness requires additional adjuvants, such as solvents and dyes. Natural dyes addition is intended to provide seed markers. This study aimed to determine the best CNSL and natural dye formulation to control maize weevil and maintain maize seeds quality during storage. The research was conducted from August to October 2018 at the Agronomy Laboratory, Faculty of Agroindustry, Yogyakarta Mercu Buana University. The research was a single factor consisted of seven treatments with four replications arranged in a completely randomized design (CRD). Treatments were combinations of CNSL concentrations with the addition of natural dyes from suji leaf and teak leaves with one untreated control. The results of the research showed that CNSL as a seed treatment botanical pesticide could cause mortality and suppress S. zeamais populations and maintain the quality of maize seeds during storage for 12 weeks. Treatments with 20% CNSL formulation concentration and the addition of natural dyes both leaf pleomele or teak leaves could cause higher mortality and push down more populations and also could better maintain seed quality than 10 and 0% CNSL formulation concentrations.

Ensuring and improving the quality of products is currently an urgent task implemented through product quality management. In connection with the spread of the COVID-19 virus, Rospotrebnadzor recommends the use of quartz lamps when disinfecting premises. The article discusses the issue of assessing the quality of a device for home use of a quartz ultraviolet irradiator OUFK-01. In accordance with the WHO recommendations, the irradiation indicator became the main one for the study. The study was carried out using an ANOVA model with several iterations. Purpose of the study: to study the variability of the irradiance index in different UV ranges depending on the source of UV radiation (UV lamp) of the ultraviolet irradiator OUFK-01. The main advantage of the analysis of variance was used – the ability to consider the interaction of various factors. The conclusions that were formulated based on the results of analysis of variance suggest that the quality of the OUFK-01 irradiator has changed. Data processing was carried out using the MS EXCEL software package. The article provides a rationale for what is meant by “quality improvement”, namely, in order not to violate the bactericidal effect, it is necessary to reduce the UV-A and UV-B ranges to acceptable values, since the effect of UV-C rays has not been fully studied, then the irradiance should be increased to the permissible wavelength range. A comparative analysis of successively modified products showed that the quality of the device increased with the replacement of the UV lamp.
