This study aims to assess the efficacy of a model innovation in enhancing both the quality and quantity of salt production in the Lekok District, Pasuruan Regency. The innovation involves integrating salt production with grouper cultivation within the crystallization house. The salt production process in this innovation utilizes filters to expedite the precipitation of impurities from seawater, which serves as the raw material. Data collection took place during both the dry and rainy seasons. In the dry season, the salt produced using a filter achieved the highest quality, designated as K1, whereas the salt produced without a filter was of K2 quality. In the rainy season, filtered and unfiltered production yielded salt of K3 quality. Nevertheless, this represents a significant advancement since salt production was previously impeded during the rainy season due to adverse weather conditions. The Return on Investment (ROI) for salt production is approximately 106.46%, and according to the Cost Benefit Environment Analysis, the salt production process is environmentally friendly. Consequently, implementing salt production innovations in the crystallization house, and utilizing filters, holds promise for augmenting the income of coastal communities in the Lekok District, Pasuruan Regency.
