<p>Rice price volatility in Indonesia remains a critical issue, affecting both consumer affordability and farmer profitability. Despite government interventions, significant price fluctuations continue, driven by regulatory changes, macroeconomic factors, supply chain inefficiencies, and climate-related disruptions. The implementation of Permentan No. 31/2017 modified rice classification standards, potentially altering market price structures and consumer purchasing behavior. This study aims to analyze the dynamics of rice prices in Indonesia in 2023, focusing on the impact of government regulations, seasonal supply variations, and external economic pressures. It examines how Permentan No. 31/2017 influenced rice price differentiation, as well as the effectiveness of BULOG’s price stabilization efforts in mitigating price volatility. This research adopts a quantitative approach, utilizing secondary data from BPS Indonesia. Monthly price trends for Premium, Medium, and Low/Non-Quality rice were analyzed from January to December 2023. A comparative assessment was conducted to examine price disparities before and after regulatory adjustments, as well as the correlation between seasonal supply cycles and price fluctuations. Findings indicate that rice prices remained stable in the first half of 2023 but surged significantly between August and December. Premium rice peaked at IDR 13,371.54 per kg, Medium-quality rice reached IDR 13,011.56 per kg, and Low/Non-Quality rice increased to IDR 12,381.31 per kg in October. The narrowing price gap between Premium and Medium rice in early 2023 suggests that regulatory changes influenced classification and market pricing.&nbsp; The study highlights the complex interplay between agricultural regulations, macroeconomic factors, and environmental risks in shaping rice price volatility. While Permentan No. 31/2017 affected price differentiation, broader market pressures drove significant instability. Future research should focus on strengthening domestic rice production efficiency, improving supply chain resilience, and enhancing government intervention strategies. Further exploration of the link between rice price inflation and household food security, as well as adaptive strategies for climate-resilient rice farming, will be crucial for ensuring long-term stability in Indonesia’s rice market.</p> <p><strong>Keywords:</strong> Rice price volatility, agricultural regulations, supply chain inefficiencies, , food security, rice classification</p>

<p>Turmeric (Curcuma longa L.)is a multifunctional plant, functional food and its production is quite high in Indonesia, but turmeric processing is very limited and the shelf life of processed products in the form of juice is low so it is easily damaged. This study aims to evaluate the combined application of Pulsed Electric Field (PEF) and Low Temperature Long Time (LTLT) treatment for producing turmeric juice that effectively eliminates microorganisms while preserving the color, aroma, and nutritional content of the final product. The goal is to achieve a commercially sterile turmeric juice in compliance with the Indonesian National Standard (SNI). Two sterilization methods were tested: (1) LTLT followed by PEF, and (2) High Temperature Short Time (HTST) followed by PEF. The Total Plate Count (TPC) after treatment was 3.0 × 10⁴ CFU/mL. The most effective method for meeting SNI sterility standards was the HTST + PEF combination, with a TPC of 0.3 × 10⁴ CFU/mL achieved at 75°C for 9 seconds. The HTST + PEF method demonstrated superior effectiveness in producing turmeric juice that meets commercial sterility standards while maintaining product quality. This study provides an efficient and practical approach for communities and industry to process turmeric juice using rapid methods that ensure safety, retain quality, and comply with SNI standards.</p>
