Abstract

Compost production in Indonesia is often hampered by conventional methods that rely on manual mixing, resulting in lengthy processing times, high labor requirements, and inconsistent compost quality. This study aimed to develop a mechanical compost mixer system featuring an innovative flow gate in a dual-brick-bin setup. The innovation is designed to improve mixing efficiency, mixture homogeneity, and energy consumption. The research was conducted in Tanjung Tebal Village, Lahat Regency, from March to June 2024, using materials such as household organic waste, animal manure, coffee husks, dry leaves, fresh leaves, and the EM4 bioactivator. The methodology investigated using a comparison of a 9HP gasoline engine and equipped with the innovative flow gate to manual methods. Parameters compared include mixing time, energy consumption, homogeneity distribution, and residual material. The results show the mechanical system reduced mixing time by up to 30% from an average of 45 minutes using manual methods to 30 minutes, mixture homogeneity increased to 95% compared to 70% with manual methods, while residual material decreased from 15% to 6%. The flow gate innovation in the dual-brick-bin system proved effective in enhancing the efficiency of the compost mixing process. Implementation of this technology has the potential to support organic waste management in rural areas, reduce environmental pollution, and promote sustainable agriculture. Further research is recommended to evaluate the system’s efficiency on a larger scale.

Abstract

The development of innovative composting systems based on appropriate technology is crucial in addressing the pressing environmental issue of organic waste management in Indonesia. This study aims to develop and test a two chamber composting system with innovative airflow gates to enhance the efficiency of organic waste processing. The system was tested using a completely randomized design with four different treatments: innovative system, standard machine, manual method, and natural method, each with three replications. The results showed that the innovative system with airflow gates achieved the fastest composting time of 20 days, with a stable pH range of 6.9-7 and optimal moisture content of 34-36%. The system also produced compost with high nutrient content, including organic carbon, phosphorus, and potassium. Additionally, the system reduced labor requirements by 93% compared to conventional methods. Soil analysis revealed that the use of compost from the innovative system significantly improved soil quality and reduced chemical fertilizer requirements by 25-50%. These findings demonstrate that the composting system with airflow gates is superior in producing high-quality compost consistently. This system also offers a sustainable solution for organic waste management in Indonesia. This innovation has great potential for widespread adoption as an effective and efficient solution for organic waste management. Further development of this system can make a significant contribution to environmental conservation efforts and agricultural productivity enhancement in Indonesia.
