. Freezing is a widely used preservation method to extend the shelf life of food, yet conventional freezing often produces large ice crystals that damage tissue structures and reduce product quality. This study aims to evaluate the effectiveness of ultrasound-assisted freezing technology in improving the quality of frozen food. A literature review method was employed, focusing on scientific publications from 2015 to 2025. The results show that ultrasound application, particularly High-Intensity Ultrasound (HIUS), can accelerate the freezing rate by enhancing ice nucleation and improving heat transfer efficiency. The formation of smaller and more uniformly distributed ice crystals helps preserve the structural integrity of food and reduces water loss during thawing. The effectiveness of this technology varies depending on the type of food material, temperature, duration, and ultrasound intensity. In animal-based products, it helps maintain texture and color, while in plant-based materials, it preserves moisture content and firmness. However, excessively high intensity may pose a risk of protein denaturation, especially in sensitive materials such as fish. These findings suggest that ultrasound-assisted freezing is a promising innovative solution to improve both the quality and efficiency of the food freezing process.

Efficiency problems in spatial planning at LSU Farm have a significant impact on the effectiveness of the production process. The proximity of raw material storage warehouses to sorting and packaging zones results in congestion that disrupts product flow and quality, as well as triggering backtracking and line crossings that are detrimental to materials management. To overcome this, the Activity Relationship Chart (ARC) method was applied which considers interactions between critical areas such as inbound, sort & repack, outbound, warehouse, employees, cold storage and outdoor offices. ARC's analysis compares the importance of connections between facilities for easier access and consumer convenience, as well as reducing unnecessary movements and improving quality control. The analysis results show that the sort & repack area with the highest Total Closeness Rating (TCR) value (117) is a priority in layout reorganization. Based on these findings, it is recommended that production input warehouses be positioned further away from sorting and packaging areas to maintain product quality and avoid chemical contamination, in line with improving overall operational efficiency.

Red rice is one of the most popular staple foods in Southeast Asia. In Indonesia, it is an alternative staple food to white rice, known for its high nutritional value. In addition to containing carbohydrates, fats, proteins, fiber, and minerals, red rice is also rich in anthocyanins, which function as antioxidants.
