Abstract

In Indonesia, 23-48 million tons of food waste are generated annually, causing economic losses of IDR 213-551 trillion or around 4-5% of GDP. Food waste offers potential for valorization into products like animal feed, organic fertilizer, and biofuel but faces challenges such as technological limitations, high costs, and safety concerns. This study examines the safety of food waste-derived products for human and animal use, focusing on applications in animal feed, the food industry, cosmetics, bio-refinery, and organic fertilizers. Key processes include contaminant removal and safety assessments, though limited studies address physicochemical, microbiological, and toxic contaminant evaluations. Identified gaps in Indonesian regulations, particularly regarding safety standards, highlight the need for clearer guidelines and support for eco-friendly technologies. Enhancing these frameworks can ensure the safe and sustainable valorization of food waste.

Abstract

The increasing volume of waste in urban areas such as Yogyakarta is not supported by adequate public awareness or effective waste management systems. This study aims to design and evaluate the performance of an IoT-based portable waste incinerator as an efficient and feasible solution for household and community use. The prototype was developed using an iterative design approach with recycled materials and low-cost IoT components. Test results show that the device maintains a stable combustion temperature of 600–800 °C and achieves an average waste volume reduction of 85%. SO₂ emission levels remain below 120 ppm, meeting environmental safety standards. The IoT monitoring system, using an ESP8266 module and DHT22 sensor, enables real-time tracking of temperature and ash accumulation and provides automatic alerts for maintenance. Financial analysis indicates that production costs can be reduced by approximately 40%, resulting in an estimated unit price below IDR 4,000,000. Market validation across five locations in Yogyakarta shows an 85% interest rate and a satisfaction score of 4.2/5. Overall, the IoT-based portable waste incinerator demonstrates technical reliability, environmental efficiency, and market viability.
