The RUFSA Program (Rusa untuk Fertilizer Sustainable Agriculture) is an innovative initiative that transforms Timor deer (Rusa timorensis) manure waste from a conservation breeding site in Cakura Village, South Sulawesi, into organic biofertilizer. The program, implemented by PT Pertamina Patra Niaga Integrated Terminal Makassar in collaboration with the local community, aims to reduce manure waste, support wildlife conservation, and provide environmentally friendly fertilizer for sustainable agriculture. The method involves collecting deer manure directly inside the enclosure, mixing it with water and EM4 activator, and regularly stirring to ensure sufficient oxygen supply during a 7–14 day aerobic fermentation process. This approach not only reduces organic waste and minimizes unpleasant odor but also decreases the risk of disease transmission. The resulting biofertilizer is applied to cultivate odot grass (Pennisetum purpureum cv. Mott), small trees, and ornamental plants such as bougainvillea (Bougainvillea sp.), demonstrating practical benefits for local agriculture. Economically, the program contributes to an annual saving of IDR 3,240,000 by reducing the dependency on chemical fertilizers. Beyond its economic outcomes, RUFSA also strengthens community participation in environmental management and raises awareness of the importance of sustainable practices. Furthermore, the program aligns with the Sustainable Development Goals (SDGs), particularly those related to food security, economic growth, responsible consumption and production, and terrestrial ecosystem conservation. Overall, the RUFSA Program exemplifies an integrative approach that combines conservation, waste management, and community empowerment to promote environmentally responsible and sustainable agricultural development.

This activity was carried out with a participatory and educational approach that directly involved farmer groups in technical training on making POC through simple fermentation methods using natural ingredients such as moringa leaves, rice washing water, organic waste, and local decomposers. Through this activity, farmers are taught stages ranging from the collection of ingredients, the process of shredding moringa leaves, mixing with complementary ingredients, to the correct fermentation techniques to produce high-quality fertilizer. The training is carried out by field demonstration methods, discussions, and hands-on practice, so that farmers not only gain theoretical knowledge, but also practical skills that can be applied independently. The results show a significant increase in farmers' knowledge, skills, and awareness of the importance of liquid organic fertilizer as an environmentally friendly alternative. In addition, the public's enthusiasm is getting higher after seeing real evidence that the use of POC moringa leaves is able to increase plant growth, crop quality, and reduce dependence on chemical fertilizers which are increasingly expensive and have the potential to damage the soil. This program not only provides economic benefits through the cost efficiency of agricultural production, but also has a positive impact on environmental conservation. This activity is expected to be a model of community empowerment based on local potential that can be replicated in other regions with similar conditions. The success of the program shows that simple innovations that utilize local resources, if managed well, can support sustainable agriculture and food security for rural communities.

Modern agriculture faces serious challenges such as climate change, soil degradation, and dependence on chemical fertilizers and pesticides, which negatively impact the environment and human health. To support sustainable food security, innovative and environmentally friendly solutions are required. One promising alternative is the use of endophytic bacteria as biological agents to enhance plant growth without relying on synthetic chemicals. This study aims to examine the role of endophytic bacteria in organic farming systems through a combination of laboratory tests and field experiments. The research stages include isolation and identification of endophytic bacteria from plant tissues, testing the ability of the bacteria to support plant growth in vitro, and applying it to organic farmland to evaluate resistance to pests and crop yields. The independent variable in the study is the type of endophytic bacteria, while the dependent variables include plant growth rates, pest resistance, and crop productivity. Data analysis was performed using descriptive statistics and ANOVA, followed by post-hoc tests to determine the effectiveness of the treatments. The results showed that treatments with endophytic bacteria, both singular and combined, significantly improved vegetative growth, reduced pest attacks, and increased crop yields compared to the control. The combination of bacterial isolates proved to have a stronger synergistic effect than single treatments. These findings demonstrate the potential of endophytic bacteria as natural biofertilizers and biopesticides to support environmentally friendly organic farming.
