Abstract
One of the important seafoods in the food consumption of humans is shrimp. Although shrimp contains proteins that are needed by the human body, sometimes it contains toxins. This is due to environmental factors or catching processes that may use toxins. Therefore, the community should take precautions when consuming shrimp. White shrimp (Litopenaeus vannamei) is one type of shrimp that is preferred because of its delicious taste. The purpose of this research is to develop a computerized system for poisonous white shrimp detection. The category of white shrimps consists of two kinds, i.e., fresh white shrimps that are caught in a natural way (class A), and poisonous white shrimps that are caught by using toxin (class B). The features used are RGB colors (red, green, and blue) and texture (energy, contrast, correlation, and homogeneity). A similarity-based classification is performed by the k-Nearest Neighbor (k-NN) algorithm. The experiment was conducted on a dataset consisting of 90 white shrimp images. The holdout validation method was used to evaluate the system. The original dataset was divided into two parts, whereby 60 images were used as training samples and 30 images were used as testing images. Based on the evaluation results, it can be concluded that the classification accuracy is 73.33%. The benefit of the developed system is to help the community in selecting good and safe white shrimps.
Highlights
Indonesia is one of the largest shrimp producing countries in the world
Research Methodology This study aims to develop a poisonous shrimp detection system for white shrimp variants
The system consisted of two subsystems, namely class builder subsystem that is intended to form a knowledge database, and classification subsystem that is used to classify the unknown shrimp categories
Summary
Indonesia is one of the largest shrimp producing countries in the world. About 77% of the global shrimp production is produced by Asian countries, including Indonesia. The achievement is largely sourced from shrimp commodities, which is US$997 million [1]. Litopenaeus vannamei (see Figure 1), is one of the best-selling shrimps and is in great demand due to its taste, and it is often offered as the main menu at restaurants. White shrimps are fast growing in Indonesia and have several advantages over other types of shrimp as they have a fast growth cycle. The shrimps are usually caught in several ways: (1) by natural means such as nets and non-toxic baits; or (2) by toxins, for example, decis, tuba, and other toxins
