Sorghum is uniquely adapted to dryland and used by the Indonesian government to optimize the utilization of dryland and increase farmers’ incomes. The objective of this study was to analyze the contribution of sorghum to increasing income and the level of welfare of dryland farmer households in Wonogiri, Central Java, Indonesia. The study was conducted from October to December 2022 using a survey method through direct interviews with purposively selected sorghum-growing farmers. A set of questions included household income and expenditure. The average total income and expenditure indicators, poverty line figures, RMW, and ERFHI were used to measure the welfare level of farmer households. The study found that the income derived from sorghum contributes 22.87% to total household income and tends to increase household income by 29.65%. According to the average total income earned, farming households were in a prosperous condition. This can be seen from the total income, which is higher than the total expenditure, the average per capita income higher than the poverty line, the average total income higher than RMW, and the value of ERFHI at 1.25. Income derived from sorghum has increased by 21.43–56.00% from less prosperous households to prosperous ones. The results of this study are expected to contribute to the existing literature on sorghum development and farmers’ income and to be a reference for policy makers in formulating poverty alleviation programs and improving the welfare of farmer households, as well as expanding sorghum development by optimizing the utilization of agroecological, economic and social resources.

The high sedimentation rate of Rawapening Lake is both an environmental challenge and a potential resource. Seedlings currently rely on single-use plastic polybags, which contribute significantly to plastic waste. The use of mineral soil as a growing medium can accelerate natural resource depletion. This study aims to evaluate the feasibility and sustainability of utilizing lake sediment as an alternative seedling media through soil block technology. An integrated Life Cycle Assessment was conducted to quantify the environmental impacts, and Multidimensional Scaling was applied to assess sustainability across environmental, technological, economic, social, and institutional dimensions. Field data from ten seedling producers using soil blocks and ten using polybags were analyzed. The results showed that soil block media reduced Global Warming Potential by 48% compared to polybags, increased phosphorus and organic matter content, and was more financially efficient, with an increase in productivity of 90.24% and a revenue cost ratio of 24.56%. Sustainability analysis classified the innovation as moderately sustainable, with the highest scores in the environmental and technological dimensions. Institutional support was identified as a limiting factor. These findings suggest that sediment-based soil block media are a viable, lower-impact alternative for seedling production, although scaling up will require policy and institutional support.

The rainfed paddy farming system faces profound vulnerabilities due to daily climate non-stationarity. This mixed-methods study in Central Java analyses daily climate signals, total rice production, and household adaptation over 25 years (2001–2025). Moving beyond simple correlation, a Principal Component Regression model integrating five climate variables and three agronomic confounders reveals a profound climate–production decoupling. The composite climate index explains only 7.9% of total production variation, while non-climate factors account for 92.1%. Physical stability is maintained through asymmetric temporal scheduling and a distinct hierarchy of responses, employing active, planned adaptations alongside passive, reactive coping. However, quantitative household evaluation reveals this tonnage stability incurs severe hidden costs; the titip gabah post-harvest system maintains a high Yield Stability Index (0.93) but yields a negative Return on Storage (−7.15%), functioning as a risk-mitigation buffer rather than a profit-maximising tool. Furthermore, climate anomalies drive the progressive alienation of traditional ethnoclimatological knowledge, forcing a cognitive shift toward hybridised decision-making. To prevent passive coping from evolving into systemic maladaptation, we propose a stratified policy framework ranging from village-level knowledge integration and Subdistrict daily risk warnings to regency-level subsidies targeted at smallholders (<0.5 ha).
