Fruits and vegetables are essential for global nutrition and economic growth, yet they are among the most perishable food commodities, contributing to major postharvest losses worldwide. Freeze drying is widely recognized as a superior preservation method that maintains the structural integrity, nutritional value, and sensory quality of fresh produce. Despite its advantages, freeze drying is energy-intensive, posing challenges for cost-effectiveness and sustainability in large-scale applications. This review explores the freeze drying process in detail, highlighting the critical operational parameters such as freezing rate, chamber pressure, shelf temperature, and sample thickness, that influence both product quality and energy consumption. Additionally, the role of cryoprotectants in preserving bioactive compounds during drying is discussed. By identifying optimization strategies for these parameters, this study aims to support the development of more energy-efficient and economically viable freeze drying systems for the fruit and vegetable processing industry.

The global expansion of ultra-processed meat products (e.g., sausages, nuggets) faces dual challenges: microbiological safety risks from conventional thermal processing and rising consumer demand for clean-label, nutritious options. High-Pressure Processing (HPP) emerges as a promising non-thermal technology to address these concerns by inactivating pathogens while preserving sensory and nutritional quality. However, its industrial adoption is hindered by significant energy efficiency and scalability constraints. This systematic literature review synthesizes recent research to critically analyze these barriers. Methodologically, we conducted a Systematic Literature Review (SLR) using databases such as Scopus, ScienceDirect, Web of Science, and PubMed, focusing on studies related to High-Pressure Processing (HPP) applications in ultra-processed meats. Our analysis reveals that HPP consumes 2.5–3.2 kWh/kg up to 26× more energy than thermal pasteurization primarily due to hydraulic system demands and adiabatic heat dissipation during batch cycling. Scalability limitations stem from batch-based processing (3–7 min/cycle), vessel size constraints (<500 L), and capital costs reaching $2.5 million per unit, resulting in only 18% adoption by large-scale manufacturers. Energy recovery inefficiencies and product matrix variations (e.g., lipid-protective effects in emulsified meats) further exacerbate these challenges. Emerging solutions include semi-continuous systems (35% throughput increase), pulsed HPP protocols (18% energy reduction), and solar-hybrid installations (40% emission cuts), though economic viability remains problematic. We conclude that while HPP offers unparalleled safety and quality benefits, its scalability and energy intensity require coordinated innovations in process engineering, renewable energy integration, and cooperative industry models to achieve sustainable implementation.

The utilization of rice straw as a renewable energy resource has received growing attention in the context of regional energy security and carbon emission reduction, particularly in Central Java, Indonesia. This review explores the potential of rice straw as a feedstock for bioethanol production, emphasizing its primary lignocellulosic components—?-cellulose, hemicellulose, and lignin—and key conversion stages, including pretreatment, hydrolysis, fermentation, and purification. In addition, the performance of various technologies for converting bioethanol into electricity is critically examined. Among these, Direct Ethanol Fuel Cells (DEFCs) are identified as the most efficient, offering conversion efficiencies of 40–60% and notable environmental advantages over conventional ethanol-fueled combustion generators. The findings suggest that the integration of high-efficiency conversion technologies with the region’s abundant rice straw resources could represent a strategic pathway toward a more sustainable and low-emission regional energy system.

Effective interpersonal communication by teachers supports learning through empathetic, argumentative, and ethical verbal and nonverbal approaches, building students’ motivation, trust, and engagement in an inclusive learning environment. This study aims to understand the interpersonal communication of Islamic Religious Education teachers in establishing positive relationships to support students' academic success. This research uses a qualitative descriptive approach with a case study design to explore interpersonal communication between Islamic Education teachers and students through participatory observation, in-depth interviews, and documentation. Data were analyzed using the Miles, Huberman, and Saldana method, which includes data reduction, presentation, and conclusion drawing. Data validity was maintained through source and method triangulation, member checking, and peer discussions. The results indicate that teachers’ interpersonal communication strategies involve a harmonious blend of verbal and nonverbal communication. Teachers deliver material through lectures, advice, and praise, while reinforcing messages with facial expressions and gestures. Values such as empathy, openness, support, positive attitudes, and equality form the foundation for building strong emotional connections with students. Supporting factors such as extended learning time and school programs also strengthen communication. Despite challenges like large class sizes and negative student perceptions, adaptive and empathetic strategies successfully create a positive and inclusive learning atmosphere.
