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

BACKGROUND AND OBJECTIVES: Substantial quantities of livestock waste and organic pollutants, such as nitrogen and phosphate, which pose environmental risks are generated from agriculture activities. A combination of paunch manure and rice straw is used as organic fertilizer. Therefore, this study confirmed sustainability of organic fertilizer from paunch manure and rice straw waste.METHODS: Data were collected through focus group discussions and the closure of questionnaires which contained 29 attributes related to environmental, economic, social, and technological dimensions. The data collected was analyzed using the Multidimensional Scaling method, Rapfish software, and Monte Carlo analysis to ascertain the level of sustainability status and leverage attributes, and examine scoring errors and variations.RESULTS: Sustainability index for organic fertilizer production was 74.55 percent. The result showed that the method contributed to the growth of sustainability in various operational phases, including the processing and commercialization of organic fertilizer. According to analysis of the four dimensions, the environmental dimension held the highest leverage value at 90.1 percent, followed by social, economical, and technological dimensions at 70.50 percent, 63.69 percent, and 73.93 percent, respectively. This study identified seven leverage attributes that are very influential to sustainability of organic fertilizer production. These include water use and raw material efficiency, potential business scale increase, market absorption, the potential for public unrest, the manager or worker level of expertise in the manufacture of organic fertilizer as well as the process used to determine its quality and output.CONCLUSION: The proposed inquiry conducted within the context of this study identified the pivotal factors that influenced organic fertilizer supply framework as the quality, quantity, and market absorption of organic production. As a result, the o use of agricultural waste as a valuable addition to a perfect social, economical, and technological development system needs to be encouraged. The study is significant because it offered information about the viability of producing organic fertilizer in Indonesia, which the government and other stakeholders may use to guide their policies and programs.
