The potency and challenges of sorghum development in tidal swamplands in Indonesia have yet to be well studied. Thus, our study is the first to evaluate the land suitability, economic performance, and strategies for developing sorghum in the tidal swamplands in Central Kalimantan. We use the land suitability evaluation method, a gross margin and profit analysis, a break-even analysis, and a competitive analysis as the methods for assessing the potency and utilization of sorghum in this study. As a tool for decision-making, SWOT was also used, followed by a quantitative strategic planning matrix (QSPM) analysis. The results show that 578,511 ha of arable land is suitable for sorghum development. Economically, sorghum farming can generate IDR 12,894,000 per ha with a revenue-cost ratio of 1.72; the break-even price would be IDR 2447 per kg, around 42% lower than the current market price. Sorghum is also more competitive than cassava (Q = 0.76), sweet potato (Q = 0.58), and soybeans (Q = 0.61) and less competitive than maize (Q = 1.33). Based on the QSPM analysis, five alternative strategies were obtained for developing sorghum in tidal swamplands: (1) optimization of productivity; (2) improvement in the quality of human resources for farmers; (3) facilitation of partnership cooperation; (4) application of site-specific technology; and (5) optimization of waste utilization. These strategies show that the expansion of sorghum planting has potential in the tidal swamplands and economic value for the community.

Background Sorghum has potential as a source of material for food, bioenergy, and animal feed, making it a worthy candidate for promotion. This cereal thrives in regions characterized by low moisture and dry conditions. To address the diminishing availability of arable dry land, it may be necessary to explore the cultivation of sorghum in tidal swamplands and sandy soils. Methods Twelve sorghum varieties were evaluated in tidal swamplands during the rainy and dry seasons, as well as in sandy soil during the dry season, using two levels of organic fertilizers to create six test environments. The experiments were arranged in a completely randomized block design with three replications. To choose sorghum varieties with features that closely resemble an idealized sorghum variety, the Multi-trait Genotype-Ideotype Distance Index (MGIDI) was utilized. Simultaneously, genotype plus genotype-environment interaction (GGE) biplots were employed to determine the best circumstances for choosing broadly adaptable varieties that exhibit desirable features, as well as to find varieties that thrive environmental contexts. Results Based on the MGIDI ranking on the average across environment, two varieties, i.e., Numbu and Kawali were selected. However selected varieties in each environment were differed due to significant variety-environment interaction. In terms of grain weight, the Soper 7 Agritan variety exhibits adaptability across diverse environments, while the Numbu variety likewise demonstrates versatility in various environmental conditions. When evaluating forage yield, several adaptable varieties have emerged. Tidal swamplands treated with a high application of organic fertilizer, as well as sandy soils, provide optimal environments for selecting broadly adaptable varieties that focus on both grain and forage yields. Conclusion Adaptable varieties differ for various groups of environments and different traits under consideration. Optimal environments for identifying broadly adaptable varieties varied by trait. The MGIDI proves to be a valuable tool for selecting varieties based on multiple traits. In parallel, the GGE biplots effectively identifies adaptable varieties based on individual traits.

Urban farming is a simple concept yet significantly impacts food security and food sovereignty for urban households. Indonesian context defined urban farming as cultivation practices, including food crops, vegetables, fruits, herbs, medicinal and ornamental plants, with some combination of fishes and poultry in urban areas, namely home yard, office yard, school garden, communal garden, and many more. This chapter aims to discuss five main topics related to the urban farming movement in Indonesia: (1) The dynamic of yard utilization and food provision policy; (2) The importance of urban farming in society; (3) Community perception and involvement in urban farming; (4) The impact of the pandemic on household food security and food supply chains; (5) Government strategy to sustain participatory urban farming. The sustainability of urban farming still requires government assistance and intervention, and private involvement through corporate social responsibility. The government must support infrastructure both in terms of policy and physical implementation to facilitate the establishment of a network of business partnerships between producer farmers and various market actors in a market chain to step up the era of urban farming industrialization.

Freshwater swamplands have significant potential as a food source; however, farming in these areas often suffers from limited technology, leading to suboptimal outcomes. This study aims to learn and enhance the local farming of the crop-duck bioindustry in freshwater swamplands, integrating adaptation to rainfall variability and promoting a circular economy, by implementing some technologies. This implementation is expected to improve agricultural production and farmer income. The study was conducted with 97 farming households from three farming groups and one group of female farmers across 75 hectares, involving approximately 1,000 ducks. The results revealed a shift in the planting schedule to adapt to rainfall changes, resulting in a longer growing season and increasing yields of duck egg production (14.69%), rice (350 kg/ha or 5.85%), and eggplant (11,945 kg/ha or 76.57%). The duration of duck maintenance ranged from 12-21 months, and the overall income increased by 26.1% for duck farming, 9.3% for rice, and 221.5% for eggplant. This study recommends continuing the integrated bioindustry model, which benefits farmers and supports sustainable agriculture.
