Abstract

Chlorophyll-a in waters is one of the important factors that determines the primary productivity/fertility of waters. Chlorophyll-a measurements can be carried out in two ways, namely conventionally by direct measurements in the field and modernly by using remote sensing technology. The aim of this research is to determine variations in the distribution of chlorophyll-a in the waters of the Ombai Strait. The data used in this research is monthly level 3 climatology data from 2003–2022 from the Aqua-MODIS (Moderate-Resolution Imaging Spectroradiometer) satellite using a remote sensing and geographic information system approach. The results of this research were that the highest chlorophyll-a concentration was found in coastal areas and the lowest concentration was found in offshore waters. According to the monthly distribution of chlorophyll-a, the highest concentration was recorded in July with values ranging from 0.251-10.486 mg/m3 with an average of 0.566 mg/m3 and the lowest concentration was recorded in November with values ranging from 0.158-2.151 with an average of 0.427 mg/m3.

Abstract

One of the fish handling techniques needed to maintain fish freshness is the cold chain application. Cold chain system is very important to be applied in the post-catch handling process to extend the fish rigor mortis phase. Fishermen and fishmongers are people who play an important role in maintaining fish freshness. The purpose of this study was to determine the fresh sardine organoleptic quality after catching until reaching consumers or initial selling. The method used is a survey method through on board direct fish handling activity observation conducted by fishermen and fishmongers at selling locations, as well as fish organoleptic tests using score sheets for fresh fish with observations based on transit time starting from fishing vessel after catching, collectors, fishmongers to the first consumers. Organoleptic quality measurement of sardine taken from fishmongers in Atapupu waters showed that sardine quality fitted for consumption with an organoleptic value of >7.
