BACKGROUND AND OBJECTIVES: Sago plant is a valuable source of raw material for the processing industry and every part is very useful for food and shelter. Moreover, by-products of the Sago processing industry are useful as animal feed and liquid waste which has not been widely used. There are limited studies on the use of Sago by-products and sustainability of Sago palm smallholder industry. Therefore, this study aimed to assess sustainability of Sago palm smallholder industry in Simeulue Regency and identify the values of each attribute in the four impacting dimensions.METHODS: This study was carried out through the direct interview method, using a questionnaire containing 35 attributes related to 4 dimensions, namely 8 attributes of economy, 12 environmental, 10 social, and 5 technological. The data were obtained from 5 entrepreneurs of Sago palm smallholder industry in Simeulue Regency, out of a total of 7 active Sago processing factories. Subsequently, the data were analyzed using Multidimensional Scaling method with rapid appraisal software. Sustainability status and leverage attributes were analyzed by Monte Carlo analysis and alternating least-squares algorithm.FINDINGS: The results showed that the general sustainability indicators in Sago palm smallholder industry had an average value of 46.03 percent. This assessment was based on the value for the economic dimension of 45.56 percent, environmental dimension of 27.89 percent, social dimension of 55.65 percent, and technological dimension of 55.03 percent. Furthermore, it was found that techniques in several processing stages or use of liquid waste, cultivation skills, and technology process contributed to sustainable development. This study provided information that production factors needed to be improved for sustainability of Sago palm smallholder industry in terms of economy and environment. However, the use of solid and liquid wastes had not been optimally used.CONCLUSION: In the economic dimension, an improvement in production factors such as the cultivation of Sago plant is important because it only relies on plant that live naturally. Furthermore, it is important to increase the use of Sago pulp as animal feed to improve the substitution of commercial rations usage, and facilitate sustainability value of the economic dimension. Meanwhile, in the environmental dimension, there should be study and socialization on the processing or use of liquid waste. This can help in addressing air and water pollution. In the social and technological dimensions, Sago farmers need to be equipped with cultivation skills to increase the value of this dimension. In conclusion, Sago palm smallholder industry in Simeulue Regency needs to be facilitated from upstream to downstream and sustain plant cultivation, and process Sago commodities using technology while suppressing negative effects on the environment.

Rapid urbanization has brought environmentally, socially, and economically great challenges to cities and societies. To build a sustainable city, these challenges need to be faced efficiently and successfully. This paper focuses on the environmental issues and investigates the ecological approaches for planning sustainable cities through a comprehensive review of the relevant literature. The review focuses on several differing aspects of sustainable city formation. The paper provides insights on the interaction between the natural environment and human activities by identifying environmental effects resulting from this interaction; provides an introduction to the concept of sustainable urban development by underlining the important role of ecological planning in achieving sustainable cities; introduces the notion of urban ecosystems by establishing principles for the management of their sustainability; describes urban ecosystem sustainability assessment by introducing a review of current assessment methods, and; offers an outline of indexing urban environmental sustainability. The paper concludes with a summary of the findings.
