Abstract

The entry of microplastic waste into pond waters come from household and fishing activities. This study aims to identify the presence of microplastics in milkfish in the Pedaleman Village pond by considering the type, color, and size of microplastics and to determine the polymers structure found in the digestive tract of milkfish. A total of 24 samples were collected directly from the pond in March to April 2023. The fish were measured for length (cm) and weight (g), and then dissected to remove the organs including digestive tract and muscle. The organs were then destroyed and microplastics were identified using microscope stereo. The fish organs were destroyed using 10% KOH after wet weight was measured. The sample were incubated for 24 hours until the organic matter was destroyed. Then, filtered using Whattman 42 paper and dried in an oven. The types of microplastics found in milkfish were fibers, films, and fragments. Fragment were the most abundant type of microplastics, followed by fiber and film. The fiber had a variety of colors, while the fragments are only found in black. The types of microplastic polymers found in milkfish intestines were polyethylene (PE), polytetrafluoroethylene (PTPE), Polymethyl methacrylate (PMMA), and nylon.

Abstract

Common carp strain Sinyonya (Cyprinus carpio) is a freshwater fish that has high economic value. The development of fisheries cultivation business has caused an increase in demand for feed and raw materials so that feed prices become uncompetitive. Therefore, it is necessary to find alternative local feed raw materials. Plant protein source that has the potential to be developed is the indigofera (Indigofera zollingeriana) which has a protein content of 28.98‒36.62%, crude fiber 8.49‒17.40%, and fat 3.3%. This study was aimed to evaluate the use of indigofera leaf flour as a feed raw material on the digestibility of common carp. This study applied the completely randomized design experimental method containing four diet treatments and three replications, namely A (control), B (30% non-fermented indigofera leaf meal), C (30% fermented indigofera leaf meal), D (30% soybean meal). Common carp with an average body weight of 5.87±0.90 g were kept in aquariums (60 × 40 × 40 cm3) with a density of 10 fish per aquarium and fed three times a day at satiation for 30 days of maintenance. The results showed that the use of indigofera leaf flour fermented using A. niger mold had a significant effect (p<0.05) on total digestibility with a value of 53.7%, protein digestibility of 84.88% and energy digestibility of 70.60% in common carp. This study also showed that indigofera leaf flour fermented using A. niger mold could reduce crude fiber in feed from 5.21% to 2.98%.

Abstract

Plastic waste discarded into the environment can easily enter water bodies. One as such for an example is the milkfish farming ponds in Kasemen Subdistrict, which have become a dumping ground for household waste. This has led to the entry of plastic waste into the pond waters, which can be degraded into microplastics. This study aims to identify the content and abundance of microplastics in fish and other fish parts such as: flesh, intestines, stomach, gills, water, and sediment, as well as to measure the water quality in the milkfish farming ponds in Kasemen Subdistrict, Serang City, Banten Province. A total of 12 milkfish were collected from 6 stations, with 2 fish taken from each station using the random sampling method across 6 hectares of the farming ponds. The quantity and types of microplastics identified in the samples were analyzed using descriptive statistical analysis with software brand Meiji Techno. The results showed that the milkfish farming ponds in Kasemen Subdistrict were contaminated with microplastics, found in the fish's flesh, gills, intestines, stomach, water, and sediment. The microplastics identified were fiber, film, and fragment types. FTIR test results indicated that the microplastics found were made of polypropylene (PP) polymer.

Abstract

Carp is a valuable freshwater fish that thrives in various temperatures and water conditions, making it suitable for cultivation in diverse regions to satisfy community needs for animal protein. However, one of the primary challenges in carp farming is the high cost of commercial feed, which can contribute up to 91.2% of total production expenses. Thus, identifying affordable alternative protein sources is essential. Indigofera zollingeriana, a protein- and amino acid-rich plant, shows potential as an alternative to traditional feed ingredients like soybean meal. This study examines the effectiveness of using Indigofera as a feed ingredient for Sinyonya carp (Cyprinus carpio). The research applied a Completely Randomized Design with 5 treatment groups, each with varying Indigofera zollingeriana concentrations: TDI 0, TDI 25, TDI 50, TDI 75, and TDI 100. Findings revealed that Indigofera-based feed significantly boosted absolute growth and daily growth rate of the fish, although it did not influence feed efficiency or survival rate. The optimal concentration was determined to be TDI 75, or 75% Indigofera. Water quality remained favorable for the fish throughout the study.

Abstract

This research was conducted in Domas Village, Pontang District, Serang Regency, Banten Province, which is a milkfish farming pond. The purpose of this study was to analyze the abundance of microplastic particles in milkfish, identify the characteristics of microplastic particles in milkfish and identify the types of polymers that make up microplastics. This study aims to provide information about microplastics in milkfish in Domas Village which can be used as a development of science about microplastic pollution. The methods used in sampling are purposive sampling and descriptive analysis in identifying microplastics. The results showed that milkfish samples, sediment and water had been contaminated with microplastics of fiber, film and fragments with different abundances at each station. The highest abundance of microplastics in meat organs had a value of 14 particles/ind of film type at station 2, the highest abundance in water came from film type with a value of 5 particles/ml, and the highest abundance in sediment came from film type with a value of 6 particles/g. The results of the FTIR test conducted showed that there were 2 types of polymers, namely polycarbonate (PC) and acrylonitrile butadiene styrene (ABS). Keywords: FTIR; Microplastic; Milkfish
