Abstract

Pellet Compost: A Practical, Sustainable, and Circular Economy-Based Solution for Household Waste Management. One type of waste that is readily available is leaf litter. Leaf litter is a major contributor to household waste. Compostable waste has great potential to be utilized optimally to provide both economic and ecological benefits. This community service program was carried out from July to November 2025 through several stages: preparation, implementation, and evaluation. The purpose of this activity is to process organic waste into environmentally friendly pellet-based compost. Pellet-based compost is a solid organic fertilizer formed into pellets. Its shelf life is longer than loose compost. Pellet compost is drier, more visually appealing, richer in nutrients, and has a higher market value. The ingredient ratio in pellet production is a key factor that determines the quality, efficiency, and final performance of the pellets. The best ingredient ratio for pellet production between compos: tapioca flour: coconut shell charcoal: and water is 10:1:1:2. The sale of coconut shell charcoal pellets yields higher profits compared to bran and dolomite, amounting to Rp. 2,478 per piece. This approach offers a practical and sustainable solution, providing ecological benefits by reducing organic waste and supporting a circular economy in waste management. This community service initiative is expected to help the community understand how to produce pellet compost, enabling them to meet agricultural needs independently without relying on external raw materials. The program demonstrates that solving environmental issues can go hand in hand with improving the regional economy. This reflects the essence of Sustainable Development Goal (SDG) 12, which is responsible consumption and production.

Abstract

Azolla microphylla as an Alternative Source of Organic Fertilizer in Rice Cultivation on Sandy Soil Field. Rice (Oryza sativa L.) is a commodity that has high economic value in Srigading Village, Sanden District, Bantul Regency. Azolla is a water fern that has high potential as a source of organic fertilizer. The use of azolla as a source of organic fertilizer is not widely known. The partner involved in this activity is Majelis Taklim Nailul Hidayah, which is not economically/socially productive, but its main livelihood is farming, especially rice. The rice cultivation system carried out by partners so far is still based on the conventional system, which utilizes chemical fertilizers. Azolla can serve as a source of organic fertilizers, acting as a substitute for or reducing the need for chemical fertilizers, thereby reducing dependence on them. The activity aims to increase partners' understanding of utilizing azolla for organic fertilizers through azolla cultivation, which is a straightforward process. The method planned for this activity involves explaining the introduction and development of azolla, as well as practicing the technique of multiplying azolla. The stages of the activity included site surveys, hands-on azolla cultivation, and the application of azolla to rice plants in sandy soil. The results showed that the partners already knew how to cultivate azolla, how to apply azolla, and the benefits of azolla on rice growth. Azolla microphylla was cultivated in ponds lined with tarpaulins measuring 2 m x 3 m x 0.5 m, using 0.5 kg of fresh azolla seedlings. Azolla was harvested 2 weekafter sowing, with one pond producing 37.5 kg of wet azolla, representing a 75-fold increase and a productivity of 12.5 kg/m³.

Abstract

Excessive long-term use of inorganic fertilizers has contributed to the decline in soil quality in Indonesia. Therefore, the use of organic fertilizers, such as compost, is considered a more sustainable alternative to improve soil fertility and health. This study aimed to evaluate the effects of various bioactivators on compost quality and its compliance with the Regulation of the Minister of Agriculture of the Republic of Indonesia No. 7763/2024. The study employed an experimental method using a Completely Randomized Design (CRD) with one factor, namely bioactivator type (control, fungal consortium, eco-enzyme, biofilm biofertilizer, and EM4), with five replicates. The data were statistically analyzed using analysis of variance (ANOVA), followed by Duncan’s Multiple Range Test (DMRT). The results showed that the type of bioactivator significantly affected compost quality. Compost treated with biofilm biofertilizer exhibited the highest quality, with organic carbon content of 10.45%, total nitrogen of 1.36%, total phosphorus of 1.31%, and a C/N ratio of 7.68, while maintaining a near-neutral pH of 7.96. In contrast, the compost without a bioactivator (control) exhibited the lowest quality. Most treatments met the compost quality standards stipulated in the Regulation of the Minister of Agriculture of the Republic of Indonesia No. 7763/2024 for pH, C/N ratio, and NPK content (<2%); however, none met the minimum organic carbon requirement (≥15%). This was attributed to the compost being harvested three months after the composting process. As composting progresses, organic carbon tends to decrease because microorganisms decompose organic matter and oxidize carbon into CO₂. The decrease is generally greater during the early stage of composting because readily decomposable organic fractions are still abundant, whereas during the maturation stage, the rate of carbon loss slows as the remaining organic matter becomes more stable and resistant to decomposition. Overall, biofilm, biofertilizer, and the fungal consortium were the most effective bioactivators, as they produced compost with the highest quality and the closest compliance with the established quality standards.
