Abstract

Agriculture is one of the key aspects of a nation’s survival. In support of the Astacita Program of the President and Vice President of the Republic of Indonesia, which aims for food self-sufficiency, this research focuses on the topic of food security. In practice, food security faces several challenges, such as production that does not meet quality standards and very low productivity levels. One example is the cultivation of Kalimantan honey bees. Honey is one of Kalimantan’s natural resources that is highly beneficial for enhancing the human immune system. According to the Indonesian National Standard (SNI) 8664:2018, the acceptable water content in honey should be less than 22%. However, in reality, the water content in honey often exceeds 22%, reaching up to 27%. The purpose of this research is to reduce the water content in honey so that its shelf life can be extended to six months, making it suitable for export. This study employs an Internet of Things (IoT) approach, involving the stages of planning, analysis, design, implementation, testing, and evaluation. The research produced a device capable of reducing the water content of  Trigona honey (27%) to meet SNI standards within 5 hours, Cerana honey (43%) within 7 hours, and Dorsata honey (30%) within 9 hours. The use of this device proved effective in lowering honey’s water content to below 22%, in compliance with SNI standards, which means the honey becomes more durable, marketable, and exportable. This research is expected to contribute to strengthening food security in the city of Balikpapan.

Abstract

This study aimed to optimize the ultrasonic–cellulase extraction (UCE) method for recovering polyphenolic compounds with high antioxidant activity from pineapple peel waste. Pineapple peel is an abundant agro-industrial byproduct containing valuable phenolic compounds with potential applications in functional foods. The extraction process was optimized by varying several parameters, including the solvent-to-sample ratio (10–50 mL/g), enzyme concentration (5–25%), pH (3–7), temperature (30°C–70°C), ultrasonic amplitude (30–70%), and extraction time (30–150 min). The optimal conditions were achieved at a solvent-to-sample ratio of 50 mL/g, enzyme concentration of 15%, pH of 6, temperature of 50°C, ultrasonic amplitude of 70%, and extraction time of 120 min, yielding the highest total phenolic content of 37.80 ± 4.21 mg GAE/g. Comparative analysis showed that the UCE method produced higher polyphenolic content (28.04 ± 1.08 mg GAE/g) and stronger antioxidant activity (IC₅₀ = 9.27 µg/mL) than enzyme-assisted extraction (EAE) or ultrasonic-assisted extraction (UAE) alone. These findings confirm the synergistic effect of ultrasonic cavitation and enzymatic hydrolysis, which enhances the release of bioactive compounds. This study highlights UCE as an effective, green, and energy-efficient technology for transforming pineapple peel waste into natural antioxidants, contributing to sustainable food processing and environmental conservation.
