Sustainability Analysis of Milkfish Aquabusiness Management on Sumbawa Island: A Bioecology, Technology, and Economic Approach

Abstract

For more than three decades, the coastal communities have utilized the coastal land of Sumbawa Island for aquaculturing milkfish (Chanos chanos). . This research was conducted in three regencies, that is, Sumbawa, Dompu, and Bima from June to October 2018. The data collection employed the method of dependent-survey and the techniques comprised dialogue, observation, and documentation. The data management of the whole attributes employed various statistical and non-statistical equations. The sustainability analysis of the management dimensions made use of the technique of Rapid Appraisal (RAP); in this study, RAP for milkfish aquabusiness or Rapmilkfish (three dimensions, thirty-eight attributes). The results of the Rapmilkfish Analysis reveal that the sustainability score of the dimension of bioecology is 77.80% (Sustainable), technology 55.96% (Quite Sustainable), economic 47.48% (Less Sustainable), and the number of sensitive attributes is 12 (31.58%). It can be concluded that the level of application of milkfish aquaculture technology is classified as environmentally friendly and positively correlated to the sustainability of natural resources (bioecology).
