The utilization of local feedstuffs is a cost-effective strategy to reduce production expenses in animal husbandry. Enhancing the nutritional quality of these feedstuffs through fermentation presents a viable approach. This study investigates the efficacy of cellulolytic bacteria in degrading fiber in three local feed materials: duckweed (Lemna minor), water hyacinth (Eichornia crassipes), and lamtoro (Leucaena leucocephala). We employed a completely randomized block design with feed types as the block and levels of starter culture as treatment. Pediococcus pentosaceus, identified for its cellulase enzyme production with a clear zone of 4 cm on starch media, was utilized as the starter culture. The experimental procedure involved spraying Pediococcus pentosaceus onto duckweed, water hyacinth, and lamtoro, followed by incubation. The results indicated that Pediococcus pentosaceus effectively produced cellulolytic enzymes and significantly reduced crude fiber in duckweed by 18.18%, in water hyacinth by 9.17%, and in lamtoro by 4.23% (p < 0.05). Additionally, the crude protein content increased in all samples: by 4.69% in duckweed, 2.71% in water hyacinth, and 2.13% in lamtoro (p < 0.05). Among the treatments, the optimal outcome was achieved with 3 ml of Pediococcus pentosaceus. This study demonstrates the potential of Pediococcus pentosaceus for improving the nutritional profile of local feedstuffs through fermentation.

The PURPOSE of the work is to determine the mass-flow characteristics of working substances and energy indicators of an installation based on a CO2 cycle with a two-stage pressure increase (Allam cycle) during oxygen combustion of methanol.

METHODS. A research methodology is presented in which the mass-flow characteristics of working substances are determined based on the reactions of combustion and synthesis of methanol and electrolysis of water. These reactions are basic for ensuring operational processes in the installation. The method is based on the molar ratios of substances participating in reactions under stoichiometric conditions. Using the thermodynamic parameters of the cycle being implemented and at a given installation power, the consumption of the working fluid, the share of carbon dioxide renewal in the cycle, the amount of methanol produced in the synthesis unit, the amount of fresh methanol, the amount of hydrogen produced in the water electrolysis unit and the amount of oxygen are determined, necessary to ensure fuel combustion processes. At the same time, the amount of commercial hydrogen is determined. Electricity consumption for own needs is determined using regulatory methods and data from equipment manufacturers.

RESULTS. The article shows that with similar values of thermal efficiency of CO2 cycles based on oxygen combustion of methane and methanol, the amount of carbon dioxide removed from the cycle for disposal is 11% less. It has been shown that a CO2 cycle operating on methanol is capable of producing commercial hydrogen simultaneously with electricity generation. The specific electricity consumption for hydrogen production is 22% less than for its production without combination with the CO2 cycle.

The article describes to eliminate possible errors in the supply of cylinders with sulfur hexafluoride and cylinders with carbon tetrafluoride to high-voltage substations for refueling switching devices such as high-voltage switches, voltage transformers, etc. Conduct an analysis of possible erroneous supplies of the two above-mentioned gases at the substation. Make an analysis of possible residuals (or shortfalls) of gas cylinders after refilling. Make an assumption about the reasons for the appearance of possible residues. Give recommendations for overcoming possible problems. Make the appropriate calculations. Propose a formula (table) for recalculating the consumption of both types of gases. Make a table for calculating the actual values of the number of supplied cylinders, related to the discreteness of the volumes of the cylinders and the switching devices themselves. Draw appropriate conclusions and make recommendations. To achieve this goal, a method was used to calculate the state of an ideal gas using software for working with spreadsheets. The article reflects the relevance of the topic and discusses the features of refueling high-voltage SF6 equipment in various climatic conditions (below minus 40-49°F). An analysis of typical ratings of high-voltage switches used at highvoltage substations was carried out. A graph is presented for converting the molar fraction (contributing to pressure) of gases into the mass fraction. A sample calculation of the number of cylinders is presented for two commonly encountered volumes of switching devices and fortyliter gas cylinders for several standard cylinder filling ratios. Presumptive conclusions are presented regarding the assessment of real errors when sending gas cylinders for refilling switching devices. The article offers an understanding of the sequence of problems associated with incorrect calculations and a complete methodology for calculating the correct volumes (mass) of gas depending on the actual types of devices used, depending on the volume of supplies pieces of equipment.

Global warming is one of the most pressing environmental issues of the 21st century, with far-reaching impacts ranging from extreme climate change to threats to biodiversity and human life. The increase in the average temperature of the atmosphere and oceans, driven by human activities, particularly greenhouse gas emissions such as carbon dioxide, methane, and nitrous oxide, exacerbates this situation. Negative effects such as polar ice melting, rising sea levels, and ecosystem disruptions threaten the survival of many species. Growing global awareness of the importance of understanding and addressing global warming has led to various initiatives, including scientific competitions focused on global warming. These activities aim to educate the public and promote innovation in finding sustainable solutions to this environmental problem. In these competitions, the role of judges is crucial in evaluating the quality and relevance of the scientific works submitted by participants. Through community engagement carried out by the Management Study Program of Universitas Bunda Mulia in collaboration with SMA Kristen Tunas Bangsa Sunter Jakarta Utara, this competition successfully inspired and nurtured young generations in facing the challenges of global warming. The event included presentations, discussions, and Q&A sessions aimed at developing creative ideas and making a real contribution to global efforts in combating global warming.
