Abstract

Highlight Research New method to synthesis nano chitosan from Vannamei shrimp with high Deacetylation Degree Nano chitosan from Vannamei shrimp can adsorb heavy metal Fe up to 81.35% Shrimp shells as an alternative adsorbents for Fe   Abstract Shrimp cultivation produces shrimp wastes in several forms, including shells from the molting process. Shrimp shell waste can be used as a source of nano chitosan. Many researches have used nano chitosan for various applications, one of which is to adsorb heavy metal pollution. This present study aimed to extract chitosan from shrimp shells and investigate the ability of nano chitosan to adsorb Fe metal. The research began by isolating chitin and chitosan from shrimp shells through deproteinization, demineralization, and deacetylation. The obtained chitosan was afterward characterized using Fourier Transform Infrared (FTIR). Furthermore, the glassy ionic method was used to synthesize nano chitosan. Nano chitosan was characterized using a scanning electron microscope (SEM), and the Fe metal adsorption ability was measured using Atomic Absorption Spectroscopy (AAS). The FTIR results showed that the synthesized shrimp shells had successfully formed chitin compounds with the appearance of the C-O-C functional group, while the chitosan compounds with the appearance of O-H and N-H groups. The SEM characterization showed that nano chitosan with a size of 173.71 nm was successfully formed with identical morphology in the form of a flat (spherical), elongated, and irregular position. The nano chitosan was able to absorb Fe solution up to 81.35%. Therefore, nano chitosan from the shrimp shells is suitable as an adsorbent of heavy metal Fe.

Abstract

Graphical Abstract Highlight Research Tuban (Indonesia) aquaculture commodities are surveyed. Aquaculture diversity in Tuban are consisted of 5 fields, namely rice field ponds, floating net cages, freshwater ponds, and brackish aquaculture ponds Aquaculture commodities in Tuban consist of 11 families and 14 species of the main aquatic production. Cyprinus carpio or common carp is one of the commodities cultivated in four different aquacultures. Abstract Fishery is a sector expected to overcome the food crisis. Indonesia is one of the leading countries in high volumes of fishery production in most of its areas, including the Regency of Tuban in East Java Province. The area of Tuban Regency is 1,839.94 km2 with the coastline covers 65 km and a sea area of 22,608 km2. This study aims to provide information regarding aquaculture production, diversity, and distribution in Tuban.  This study used a survey method in collecting fishery commodity data directly from aquaculture areas. The results of this study showed that the highest production came from the brackish water with a value of 32.46% (13,561.79 tons), followed by rice field pond (27.79% or 11,612.45 tons), freshwater pond (25.76% or 10,764.62 tons), floating net cage (13.97% or 5,836.59 tons), and marine (0.1% or 5.67 tons). Aquaculture biodiversity in Tuban consisted of 11 families and 14 species of the main aquatic produces, such as Cyprinidae (Cyprinus carpio, Barbonymus gonionotus, Parastromateus niger), Clariidae (Clarias bathracus), Pangasiidae (Pangasianodon hypophthalmus), Penaeidae (Penaeus monodon, Litopenaeus vannamei), Channidae (Channa striata), Cichlidae (Oreochromis niloticus, Oreochromis mosammbicus), Osphronemidae (Osphronemus gourami), Serranidae (Epinephelus), Lutjanidae (Lutjanus), and Chanidae (Chanos chanos). Cyprinus carpio or common carp is fish cultivated in four different aquacultures, namely rice field pond, floating net cages, freshwater ponds, and brackish aquaculture ponds. Unfortunately, the diversity and production of marine aquaculture has not been improved even though Tuban has large marine areas.
