IMPROVING THE QUALITY OF BLACK COTTONSEED OIL WITHOUT RE-CIRCULATION INTO THE FUZA FRYING SYSTEM
type: item
description: The refining of black cottonseed oil is often complicated by the presence of impurities such as phospholipids, free fatty acids, pigments, and suspended solids. Conventional processing involves re-circulating the sediment (fuza) back into the frying system, which increases energy consumption and negatively affects oil quality. This study proposes an alternative approach that eliminates fuza re-circulation by integrating physical separation, centrifugation, and chemical refining methods. The results demonstrate improved oil quality, reduced acidity, and enhanced economic efficiency. The proposed method offers a sustainable and industrially viable solution for modern oil processing plants.

OPTIMIZATION OF EXTRACTION AND PURIFICATION METHODS FOR BLACK COTTONSEED OIL
type: item
description: Black cottonseed oil, characterized by its high content of gossypol and dark pigments, presents significant challenges for industrial food applications. This study focuses on the optimization of extraction and purification processes to maximize oil yield while minimizing toxic impurities. Using Ultrasound-Assisted Solvent Extraction (UASE), we evaluated the influence of temperature, solvent-to-solid ratio, and extraction time. The results indicate that an optimized temperature of 55°C and a ratio of 10:1 provide a maximum yield of 22.45%. Furthermore, a multi-stage purification protocol involving phosphoric acid degumming and alkali neutralization reduced the gossypol content by 98.2%. This research provides a technical framework for transforming crude black cottonseed oil into a high-quality, safe edible product, balancing efficiency with chemical safety standards.

DEVELOPMENT OF AN IOT-ENABLED CLOUD PLATFORM FOR MEASURING SPECIFIC ENERGY CONSUMPTION IN MANUFACTURING SYSTEMS
type: item
description: The rapid evolution of Industrial Internet of Things (IoT) technologies has provided new opportunities for enhancing energy efficiency in manufacturing systems. This study presents the design and implementation of a scalable, cloud-based IoT platform specifically engineered to monitor and analyze specific energy consumption (SEC) in manufacturing environments. Given that industrial sectors in developing economies, such as Uzbekistan, often exhibit energy intensities significantly higher than global benchmarks, the development of localized, low-cost monitoring solutions is imperative. The proposed system integrates high-precision electrical sensors (PZEM-004T), microcontroller units (ESP32) for edge data processing, and a centralized cloud-based dashboard for real-time visualization and analytics. The research methodology involves the deployment of the platform within a medium-scale manufacturing facility to evaluate its performance in tracking SEC—defined as the energy required to produce a single unit of output. Statistical analysis of the collected data reveals that real-time visibility into energy use patterns allows for the identification of non-productive energy peaks and operational inefficiencies. Results indicate that the system achieves a measurement accuracy of 98.5% compared to commercial laboratory-grade meters, while offering a cost reduction of nearly 70% in hardware expenditure. Furthermore, the discussion highlights how the platform supports decision-making for energy-saving interventions, potentially reducing total energy costs by up to 15%. This research contributes to the regional literature on Industry 4.0 transition in Central Asia, providing a practical framework for digitalizing energy management in local industrial contexts.

ADSORPTION BEHAVIOR OF MOLYBDENUM IONS ON A CPVC-BASED ANION-EXCHANGE SORBENT: KINETIC, ISOTHERMAL, AND MECHANISTIC ASPECTS
type: item
description: This study examines the adsorption behavior of Mo(VI) ions on a chlorinated polyvinyl chloride (CPVC)-based sorbent under static conditions at various concentrations and temperatures. Kinetic results revealed rapid initial uptake followed by a slower approach to equilibrium, suggesting a two-stage adsorption mechanism. Adsorption capacity increased slightly with increasing temperature, indicating improved ion mobility and diffusion. Equilibrium analysis revealed that the process conforms to the Langmuir isotherm model, confirming monolayer adsorption on a homogeneous surface. Thermodynamic parameters revealed that the adsorption process is spontaneous and endothermic, with increasing disorder at the solid–solution interface.

DETERMINATION OF THE CRITICAL MICELLE CONCENTRATION IN SURFACTANT SOLUTIONS
type: item
description: This study investigates the determination of the critical micelle concentration (CMC) and cloud point of synthesized surfactants, which are key parameters governing their physicochemical behavior in aqueous solutions. Surfactants, due to their amphiphilic nature, exhibit the ability to reduce surface tension and form micelles beyond a certain concentration threshold. The CMC was determined using surface tension measurements via the Du Noüy ring method, while the cloud point was established through controlled heating of surfactant solutions. Experimental results showed a decrease in surface tension with increasing concentration until a plateau region corresponding to micelle formation was reached. The synthesized surfactants demonstrated varying CMC and cloud point values, indicating differences in molecular structure and hydrophilic–lipophilic balance (HLB). Among the samples, PAVMS exhibited the highest surface activity, while PAVKM showed favorable characteristics for applications at lower temperatures due to its low CMC and cloud point. The findings highlight the importance of molecular structure in surfactant performance and provide a basis for selecting efficient and environmentally sustainable surfactants for industrial applications.
