BACKGROUND AND OBJECTIVES: Food estate initiative is an Indonesian government program designed to achieve food security though the cultivation of strategic commodities on large-scale agricultural land. Despite being controversial due to the scale of land use and budgetary requirements, the viability of the program has been questioned by critics pointing to the failure of a similar initiative in the past. In other words, there is widespread pessimism regarding sustainability of food estate program. Therefore, this study presents a new approach to farming sustainability investigation, assessing seven aspects including economy, society, environment, institutions, technology, market, and culture. The objective was to compare the value and status of sustainability as well as design land use planning strategies.METHODS: Respondents of the questionnaire were 50 food estate farmers, selected from Pollung sub-district, as well as 50 non-food estate farmers from Dolok Sanggul and Lintong Nihuta Sub-districts. Multiaspect Sustainability Analysis software was used to conduct data analysis with Multidimensional Scaling approach. Primary data was collected through interviews using questionnaires and seven aspects analyzed include economic, social, environmental, institutional, technological, marketing, and cultural, with several factors. In addition, a total of 45 indicators were used to compare sustainability of farms, including 7 economics, 6 social, 9 environmental, 5 institutional, 7 technological, 5 marketing, and 6 cultural.FINDINGS: The results showed that in Food Eestate farming, sustainability value for economic aspects was 47.57, social 50, environmental 72.22, institutional 50, technological 50, market 53.4, and cultural 33.33. On the other hand, sustainability value of non-Food Eestate farming estate was 33.29 for economic, 47.17 for social, 77.78 for environmental, 56.6 for institutional, 42.86 for technological, 36.6 for market, and 41.67 for cultural aspects. The overall sustainability value of Food Eestate farming was 50.93, which was slightly higher than non-food estate score of 48. Improving all aspects in the third scenario is the most favorable approach for improving farming sustainability. Based on the results, 12 sustainability indicators were found to be relevant for designing land use planning strategies. These indicators had different implications for stakeholders in improving sustainability.CONCLUSION: Sustainability value of food estate farming exceeded that of non-Food Eestate but both were in the moderate category. Higher sustainability scores were recorded in economic, social, technological, and marketing aspects for Food Eestate farming, while higher scores were found in environmental, organizational, and cultural aspects for non-food estate . This study recommended implementing land use strategies such as multiple cropping for Food Eestate farming, and crop rotation for non-food estate. To implement the strategy for Food Eesrare farming, the government needed to increase fertilizer subsidies, provide agricultural insurance, relevant technology, extension services on land leases, agricultural sustainability, and water management. For non-food estate farming, the recommendations included providing capital loans, extension services on land tenure, agricultural sustainability, land conversion, inorganic fertilizer dosage, and weed management.

BACKGROUND AND OBJECTIVES: Sorghum is a grain-producing commodity with the seeds being a food source, while the leaves, stems, and bran serve as animal feed. The productivity depends on the specific variety, environment, infrastructure, and technology used. Sorghum cultivation in Indonesia is carried out primarily using agroforestry or monoculture. Despite not being as popular compared to rice and corn due to the prevalence of these staples in Indonesian diets, sorghum has the potential to replace corn because its cultivation is easier and the results are more profitable. Therefore, this study aimed to determine sustainability index and potential of sorghum for food and feed by identifying dimensions and attributes that influence sustainability.METHODS: This study was conducted at Raji, Demak, Central Java, Indonesia in 2023. Data were collected through focus group discussions and structural questionnaires consisting of 28 attributes associated with environmental, social, economic, and technological dimensions. Multidimensional scaling method and Rapfish software were used for data analysis. Monte Carlo analysis was used to ascertain sustainability level and attributes leverage, as well as check errors and variations in assessment.FINDINGS: The results showed that sustainability index of sorghum for food and feed was 79.67, categorized as very sustainable. Analysis across four dimensions showed that the social dimension had the highest (83.80) sustainability index, followed by the technological (82.28), economical (77.46), and environmental (75.15) dimensions. A total of 12 attributes were found to greatly affect sustainability. These included land availability, the efficiency of water used, the prevention of natural resource exploitation, motivation level, minimal interference with primary agricultural activities, community acceptance, productivity, sales profit level, ease of sale and cultivation, tools availability, and technological sensitivity.CONCLUSION: Sustainability index of sorghum for food and feed was categorized as very sustainable with a value of 79.67. This index consisted of the environmental (75.15), social (83.80), economical (77.46), and technological dimensions (82.28). The average productivity at the study site was 6-7 tons per hectare, with a production potency of 300-350 tons per year. Additionally, the potency of sorghum stover production was 471.8 ton per year of dry matter and could be used as feed for 163 animal units per year
