2) Operational Activities on Land
a. Cleaning and Weighing

Figure 3. Cleaning and weighing activity

The caught fish that have been landed are then weighed dirty.
After being weighed dirty, then the fish are cleaned of dirt or
unnecessary fish parts such as gills and entrails. After the fish
are clean, they are then weighed clean, and the weight of the
fish is recorded, for further processing.
b. Processing
Tuna fish processing activity is freezing tuna. The clean and
recorded fish are then put into the freezer. The purpose of this
stage is to prevent and slow down the process of spoilage in
tuna. Freezing is a method / method of preserving food by
freezing tuna at temperatures below freezing. With the
freezing process, the activity of enzymes and micro-
organisms becomes inhibited or can be stopped so that the
quality of tuna can be maintained. The freezing process of
tuna can preserve tuna because tuna only undergoes a very
slight quality change process during the freezing, frozen
storage, and distribution processes so that the quality value of
