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.

Abstract

The use of conventional plastics, which are difficult to degrade, has caused serious environmental problems, necessitating alternatives in the form of biodegradable plastics (bioplastics). Biofilms are anticipated to address social issues in line with the 12th SDG goal, namely the management and reduction of packaging waste generated daily. By utilizing abundant local cassava starch, the produced biofilms are anticipated to possess good mechanical properties and low water absorption, making them a potential eco-friendly alternative for food packaging while supporting the use of local resources. This study aims to develop cassava starch-based biofilms as environmentally friendly packaging by optimizing the formulation of carboxymethyl cellulose (CMC) and glycerol. The research employs cassava starch as the primary matrix, CMC as a filler to enhance mechanical properties, and glycerol as a plasticizer to improve the flexibility of the biofilm. The research methods include cassava starch extraction, mixing of materials with stirring and heating, and drying the gel into a biofilm. The biofilm's characteristics were analyzed through tensile strength and elongation tests. The results showed that the formula with a cassava starch concentration of 15 grams, 1% CMC, and 6% glycerol yielded the highest tensile strength value of 1.56 MPa, meeting the Japanese Industrial Standard (JIS) for edible films (≥ 0.392 MPa). The best elongation value reached 199.6%, demonstrating excellent flexibility according to JIS and Indonesian National Standards (SNI). This study indicates that the appropriate combination and concentration of materials can produce biofilms with the potential to replace conventional plastics, support environmental sustainability, and optimally utilize local resources
