Feasibility of Solid Waste Tuna Loin of Yellowfin Thunnus albacares Raw Materials for The Product Diversification

Abstract

Indonesia is one country in the world exporters of tuna in the form of fresh, frozen and
processed. Tuna exported in processed form large enough to leave waste for exporting companies.
The purpose of this study was to determine a feasibility study on solid waste exported tuna loin for
raw material diversification. This research was conducted in Majene Makassar Strait. The study was
conducted using descriptive exploratory method by taking a sample of 3 times and each sample
was tested 3 times resulting in 9 times of testing for each of the observed variables. Chemical test
which includes moisture, protein, fat, ash, carbohydrates, and histamine. Microbiological test that
is E. coli, Salmonella and the total number of bacteria. Data were analyzed by descriptive qualitative
and quantitative display via Tables, Graphics and Image in the form of average value. The results
showed that the chemical solid waste tuna loin has a water content ranged from 78.34 to 78.78%,
protein content ranged from 14.32 to 16.41%, fat ranged from 1.56 to 1.66%, ash content ranged
from 5.18 to 5. 58%, carbohydrate content ranged from 1.29 to 1.34%, and histamine ranged from
2.08 to 3.21 mg / kg. Solid waste microbiologically tuna loin contains E.coli range from 1.2 to 1.9
(<2), Salmonella negative and TPC ranged from 1.4 to 1.8 x 105 kol/g. The results of chemical and
microbiological testing showed solid waste tuna loin still suitable as raw material diversification
products.
