Abstract

Blue Swimming Crab (Portunus pelagicus) has a calcium content of 19.97% which can be fortified in biscuit products. The purpose of this study was to understand the impact of using crab shell flour in biscuits on panelist preferences. The study was conducted from July to August 2024 at the Fisheries Product Processing Laboratory, Faculty of Fisheries and Marine Sciences, Padjadjaran University. The method used in this study was experimental using Friedman data analysis consisting of 4 treatments and 20 replications in the form of semi-trained panelists on organoleptic parameters, namely appearance, aroma, taste, and texture and chemical parameters, namely calcium content, water content, ash content, protein content, fat content, and carbohydrate content. The results of the hedonic test proved that the addition of 5% crab shell flour was the most preferred treatment, with an average appearance value of 7.9; aroma 8.2; taste 8.1; and texture 8.1. Based on chemical analysis of the most preferred treatment, namely the addition of 5% crab shell flour produced a calcium content of 1.98%; water content 2.11%; ash content 3.45%; protein content 12.35%; fat content 9.91%; and carbohydrate content 72.18%.

Abstract

The Bojongsoang Wastewater Treatment Plant (IPAL) in Bojongsoang District, Bandung Regency, West Java, is a facility that processes wastewater from the city of Bandung. In the IPAL pond, there are Nile tilapia that live there and can serve as bioindicators of water quality. However, these fish are utilized by the surrounding community through fishing and netting for consumption and sale. This study aims to determine the safety level of Nile tilapia (Oreochromis niloticus) meat in the Bojongsoang IPAL based on the content of heavy metals Cu and Zn. The research was conducted from May to October 2024. The method used is a survey method with purposive sampling technique conducted at four pond sample collection locations. The accumulated heavy metal content in the Nile tilapia meat from the Bojongsoang IPAL Treatment Pond is as follows: Cu (0.1649 mg/kg, 0.1199 mg/kg, 0.1896 mg/kg, 0.1825 mg/kg) and Zn (2.5308 mg/kg, 1.9651 mg/kg, 2.3628 mg/kg, 2.5125 mg/kg). The levels of these heavy metals are still below the maximum limits set by Ditjen POM RI in 1989, indicating that the Nile tilapia meat collected from the Bojongsoang IPAL Treatment Pond is still safe for consumption based on its Cu and Zn heavy metal content.
