Abstract

Pulau Baai Port is a crucial resource used as the main sea transportation route for some commodities and goods needed by principals when traveling to or from Bengkulu. Data collection was carried out at three stations The method used to determine stations is purposive sampling. Water quality data collection was also carried out at the three stations. The fish identification method is carried out by looking at morphological characteristics to facilitate classification using the Marine Fishes of the south identification book. A total of 18 species of fish found in the waters of the City of Bengkulu landed at the port Pulau Baai namely white pomfret fish (Pampus argenteus), black pomfret fish (Parastromateus niger), mackerel fish (Scomberomorini), mujair fish (Oreochromis mossambicus), beledang fish (Trichiurus lepturus), next fish (Pleuronectiformes), manyung fish (Arius thalassinus ), kerong kerong fish (Terapon jarbua), sea cork fish (Channa striata), big eye tuba fish (Thunnus obesus), mullet fish (Moolgarda seheli), anchovies (Engraulidae), mackerel fish (Scomberomorini), beleberan fish (Opisthopterus tardoore), Cladi fish (Osphronemus goramy), Kape-kape fish (Pentaprion longimanus), Gulamo fish (Johnius trachycephalus), and Sengin fish (Eleutheronema tetradactylumThen, from the results of calculating the diversity index at these three stations, the values range from 2.46-2.07, (medium). It can be concluded that the results of the ecological analysis at the three stations have moderate diversity with a uniform composition and no species dominates.

Abstract

Fish have the potential to be contaminated with heavy metals such as lead, which can originate from human activities, industry, and ports. The Bengkulu people have a traditional processing method that is believed to reduce heavy metal content in fish through the immersion of fish in Pendap dishes using water and lemon. This study aims to observe the reduction of heavy metal content in fish during the immersion process using water and lemon juice in Pendap dishes. The research was experimental with positive and negative results and analyzed using the SPSS ANOVA test to see significant differences between treatment groups. The fish used as samples included Tongkol Sarda orentalis, Kembung Rastrelliger kanagurta, Tuna Thunnus albacares, and Tenggiri Scomberomorus Lacepède. The parts of the fish that were analyzed included the muscles, liver, and gills. All samples were exposed to Pb(NO3)2 and divided into 3 treatment groups: 1 positive control, 2 precipitated with water, and 3 precipitated with lemon juice (Citrus limon). The samples were tested using the reagents NaOH, KI, NH4OH, and HCl. Based on the research results, it was found that the application of lemon juice produced significant results in reducing Pb levels, as indicated by the negative test results.
