Abstract
Abalon (Haliotisasinina) is a marine animal that is classified in shellfish and belongs to the class of gastrophoda, family haliotidae. It is one of the mainstays of NTB and national ethnofauna as marine commodities for export. The existence of these snails has provided an important role for the economy of coastal communities not only eaten or sold in the local market but also exported to several Asian countries, Europe and the United States. Thus, the growth of Abalone is very important to know quickly so that the process of abalone cultivation becomes more effective. Abalone growth is a logistical problems, Abalone growth can be observed through changes in weight, length and biomass. this study focused on the growth of abalone length as a continuation of previous research. The length of Abalone is also one of the parameters of successful cultivation and marketing. It should be noted that knowing the growth of Abalone is quiteslows so this also becomes an interesting phenomenon to study. Slow growth is certainly one of the economic problems because it is related to the time of marketing or harvesting. One way to know quickly the growth of abalone is to construct the mathematical modelso that based on the results of analyzing the model can be known the optimal length and time of harvesting. The mathematical model constructed in this case is the Von Berlatanffy model as a generalization of the Verhulst logistics model. Based on the results of analysis of the model obtained the growth of the length of the Abalone reaches a maximum of 12 cm at the age of 80 months. However, harvesting at that age is less effective because it will require more maintenance costs so that the optimal harvesting time is 26 months with an abalone length of 8 cm and the length is said to be the optimal length because it meets national or international market standards.Abalon (Haliotisasinina) is a marine animal that is classified in shellfish and belongs to the class of gastrophoda, family haliotidae.
