Abstract

Background: The growing reliance on synthetic inorganic nutrient solutions in hydroponic agriculture poses significant ecological, economic, and food safety concerns, necessitating the evaluation of sustainable organic alternatives that can maintain crop productivity while reducing chemical inputs. Objective: This study determined the optimal LOF substitution ratio for inorganic nutrient solutions in Nutrient Film Technique (NFT) and Deep Water Culture (DWC) hydroponic systems, evaluating effects on plant growth, yield, leaf nitrate accumulation, and solution chemistry in lettuce (Lactuca sativa L.). Methods: A 5 × 2 factorial experiment was conducted with five LOF substitution levels (0%, 25%, 50%, 75%, 100%) across two hydroponic system types (NFT and DWC), using lettuce (Lactuca sativa L. cv. Grand Rapids). Parameters measured included plant height, leaf area index, fresh weight, dry weight, root length, chlorophyll content (SPAD), leaf nitrate concentration, and nutrient solution EC, pH, and dissolved oxygen. Results: The 75% LOF + 25% inorganic treatment (T2) produced statistically equivalent fresh weight (142.3 ± 7.1 g/plant, NFT) to the full inorganic control (148.7 ± 6.4 g/plant; p = 0.312), while reducing leaf nitrate by 34.2% and fertilizer input costs by 50.3%. Full LOF (100%) significantly reduced yield by 39.9% but achieved the greatest nitrate reduction (57.7%). Conclusion: Substituting 75% of inorganic nutrient solution with LOF is agronomically viable, economically advantageous (50.3% cost reduction), and improves food safety in hydroponic lettuce production, supporting circular bioeconomy principles in precision-managed soilless cultivation.

Abstract

This study investigates the supply chain efficiency of rice commodities in Indramayu Regency and its implications for improving farmers' profit margins. Indramayu Regency is one of Indonesia's principal rice-producing regions, yet farmers continue to receive disproportionately low returns due to inefficiencies across the supply chain, including excessive intermediary layers, high post-harvest losses, and weak market integration. This study employs a quantitative approach using survey data from 120 rice farmers and 45 supply chain actors selected through stratified random sampling. Data were collected between January and June 2024. Analytical methods include marketing margin analysis, farmer's share analysis, Supply Chain Operations Reference (SCOR) efficiency scoring, and multiple regression to identify determinants of profit margin. The results show that farmers retain only 42.6% of the final consumer price (Channel III), compared to 68.4% in the shortest marketing channel (Channel I). Supply chain efficiency scores averaged 0.73 across all actors, with rice millers recording the highest efficiency (0.87) and farmers the lowest (0.61). Regression analysis confirms that channel choice, access to milling technology, and cooperative membership significantly improve profit margins. The findings suggest that policy interventions focused on reducing intermediary dependency, strengthening farmer cooperatives, and investing in post-harvest infrastructure can substantially increase rice farmers' income in Indramayu Regency.

Abstract

Background: Climate change poses unprecedented challenges to global agriculture, threatening food security and farmer livelihoods worldwide. Climate-smart agriculture (CSA) has emerged as a transformative approach to address these challenges through practices that enhance productivity, build resilience, and mitigate greenhouse gas emissions. Objective: This study examines the comprehensive effects of CSA practices on farmer income and environmental sustainability across diverse agricultural contexts. Methods: Utilizing a mixed-methods approach with data from 384 smallholder farmers across multiple regions, this research employs multivariate regression analysis and environmental impact assessments to evaluate CSA adoption patterns and outcomes. Results: Results demonstrate that CSA adoption significantly increases farm productivity by 28-45%, farmer income by 35-52%, and reduces greenhouse gas emissions by 18-32% compared to conventional practices. Conclusion: The study reveals positive correlations between CSA intensity and household income diversity, with particularly strong effects on resource-use efficiency and climate resilience. These findings contribute to the growing evidence base supporting CSA as a viable pathway for sustainable agricultural development and provide actionable insights for policymakers, extension services, and development practitioners seeking to promote climate-resilient farming systems.

Abstract

Background: Integrated crop management (ICM) is promoted to raise rice productivity while containing production costs. Cirebon Regency, West Java, is a major rice producing area where smallholder farmers face stagnating yields and rising input prices. Objective: This study evaluated the effect of three levels of ICM implementation on rice grain yield, itemized production cost, and farm profitability under the agroecological conditions of Cirebon. Methods: A randomized complete block design with three treatments (conventional, partially integrated, and fully integrated crop management) and four blocks was carried out on 1.5 ha of coastal alluvial paddy land during the 2023 dry season using the Inpari 32 variety. Yield, agronomic variables, and itemized costs were recorded and analyzed by ANOVA followed by Tukey HSD at the 5 percent level after assumption testing. Results: Fully integrated crop management gave the highest grain yield and the lowest production cost, raising the benefit cost ratio from 1.60 to 2.44 and almost doubling net farm income relative to conventional practice. Partially integrated management was intermediate. Detailed percentage changes are reported in the results section. Conclusion: ICM is agronomically effective and economically attractive for smallholder rice farmers in Cirebon. Practically, the findings give extension services a locally calibrated cost benefit reference for site specific nutrient and water management, and show that the required investment is recovered within one cropping season. Because the trial covered one season at one site, the gains should be confirmed across seasons, varieties, and soil types before wider recommendation.
