Intensive nickel mining activities in North Morowali Utara Regency have resulted in severe environmental degradation, including soil damage, biodiversity loss, and water pollution. This study aims to analyze the impact of sustainable integrated farming development as a reclamation strategy for former nickel mining land, and to evaluate the sustainability of this system from economic, ecological, and social perspectives. The research was conducted in Molores and Molino Villages using an exploratory qualitative approach, with data collected through interviews, field observations, focus group discussions (FGDs), and Multidimensional Scaling (MDS) analysis based on the Rapfish method. The findings indicate that the implementation of integrated farming combining agriculture, livestock, aquaculture, and organic waste processing can effectively restore soil fertility, increase household income, and enhance community resilience in food and energy. The sustainability index indicated a "moderately sustainable" status, with the highest score observed in the economic dimension. This system also reduces community dependency on the mining sector and promotes active participation in environmental conservation. Sustainable integrated farming has proven to be an effective, community-based reclamation solution and is highly replicable in other post-mining areas.

Organic waste can be processed into environmentally friendly fertilisers that support plant growth and reduce environmental pollution. This study evaluated the effects of black soldier fly frass, bioslurry, and organic compost at different application rates on the growth and biomass of water spinach (Ipomoea reptans Poir.). The experiment was conducted from November 2025 to March 2026 at PT Swen Inovasi Transfer, Bogor, Indonesia, using a completely randomised design. Treatments consisted of three organic fertiliser types applied at 0, 100, 200, and 300 g per polybag. Plant height, leaf length, number of leaves, and fresh weight were observed. Data were analysed using analysis of variance followed by Duncan’s Multiple Range Test at the 5% significance level. Fertiliser type, application rate, and their interaction did not significantly affect plant height, leaf length, or number of leaves, but significantly influenced fresh weight. The highest fresh weight of 8.40 g was obtained with 200 g frass and 200 g bioslurry treatments. These results indicate that frass and bioslurry at 200 g per polybag are promising for increasing water spinach fresh biomass.

Rapid population growth has generated significant environmental challenges, particularly in waste management, which remains a national strategic issue in Indonesia. Waste management is regulated under Law No. 18 of 2008 on Waste Management and strengthened through Presidential Regulation No. 97 of 2017, which outlines the National Policy and Strategy for Household Waste and Similar Waste Management. One approach to reducing household waste is the TPS-3R (Reduce, Reuse, Recycle) program, which emphasizes minimizing waste volumes and improving waste characteristics prior to disposal at final landfill sites (TPA). This study aims to evaluate the performance of the TPS-3R program in Bogor City in terms of its effectiveness in reducing household waste. The evaluation applied the CIPP model (Context, Input, Process, and Product). The findings show that the Context aspect is strong, as the program aligns with national regulations, has a clear legal foundation, and meets the objective of reducing waste at its source through community participation. The Input aspect is adequate but requires improvement: TPS-3R facilities generally meet basic standards; however, human resources are still limited, with managerial and technical roles often carried out concurrently, and maintenance funding remains insufficient. The Process aspect is also rated adequate: available facilities are only utilized at 50–70%, while training and capacity building for TPS-3R managers are conducted more than three times annually. Funding primarily relies on community contributions, government allocations, and revenues from recyclable products. The Product aspect shows partial success: TPS-3R facilities contribute to waste reduction and generate by-products that provide supplementary income, yet overall waste reduction targets outlined in the Regional Waste Management Strategy (Jakstrada) have not been fully met. In conclusion, optimizing both input and process components is crucial to enhance TPS-3R performance and achieve the national target of reducing waste by 30% by 2025.
