Abstract

By product Muarenesox talabon swim bladders can be used as a raw material for desperately needed in the food, biomedical, pharmaceutical, and cosmeceuticals industries. The aims of the research were to observed the histological and determine chemical characteristics of swim bladder including proximate and amino acids; extraction of acid soluble collagen and determine the characteristics of collagen including proximate, pH, heavy metals, microbial, amino acids, functional groups, molecular weights, and thermal stability. The morphology of cunang swim bladder consists of outer, middle, and inner layers containing collagen fibers; 33.67±0.71%wb and protein whichwere dominated by three amino acids that were glycine, proline, and alanine. Pretreatment by 0.1 M NaOH for 8 hours (K1T4) and acid extraction by 0.25 M acetic acid for 72 hours (M1T3) was the best treatment yielding 14.51± 0.43% of collagen; having 12.12±0.04% wb of moisture; 88.54 ± 0.08% wb of protein; 1.31±0.23% wb of fat; 0.17±0.03% wb of ash. Not detected any heavy metals (Pb, Hg, As, Cd). Acidity pH was 4.31 and negative of E. coli and Salmonella. The main amino acids detected were glycine 241.06 mg/g; proline 88.73mg/g; and alanine 86,98 mg/g; FTIR spectra were revealed the presence of triple helix structures; electrophoresis patterns consisted of 136 kDa of mol weight of α1 and 117 kDa of mol weight of α2 were characterisedto be type I collagen; which had Tmax of 195.59ºC and ΔH 7.8113 J/g. Keywords: acid extraction, swim bladder, collagens, thermal stability

Abstract

Proses produksi garam di Provinsi NTT selama ini, khususnya di UD. Abraham, Desa Oli’o, Kabupaten Kupang, yaitu menggunakan metode konvensional. Metode konvensional yang diterapkan melalui proses penguapan (evaporasi) air laut dengan memanfaatkan panas dari sinar matahari. Polusi sampah   plastik   menjadi   ancaman terhadap kondisi laut saat ini yang secara global produksinya semakin meningkat drastis setiap tahunnya. Beberapa penelitian telah dilakukan terkait mikroplastik pada air dan garam membuktikan adanya cemaran atau kandungan partikel mikroplastik. Tujuan dari penelitian ini adalah untuk mengetahui kandungan mikroplastik pada air bahan baku dan partikel garam “krosok”. Metode yang digunakan dalam penelitian adalah pengujian terhadap keberadaan, kelimpahan dan bentuk mikroplastik. Data penelitian dianalisis secaradeskriptif kuantitatif. Hasil penelitian membuktikan bahwa adanya cemaran mikroplastik pada semua sampel air tambak (K1, K2, K3, K4, K5, K6) dan partikel garam “krosok” (GK) dengan total kelimpahan bentuk fragmen (70 partikel/g), fiber (46 partikel/g) dan film (36 partikel/g). The salt production process in NTT Province so far, especially at UD. Abraham, Oli'o Village, Kupang Regency, namely using conventional methods. This method is applied through the evaporation process of sea water by utilizing heat from sunlight. Plastic waste pollution is a threat to current marine conditions, whose global production is increasing drastically every year. Several studies have been carried out regarding microplastics in water and salt, proving the presence of contamination or the content of microplastic particles. The aim of this research is to determine the microplastic content in raw material water and "krosok" salt particles. The method used in the research was testing the presence, abundance and form of microplastics. Research data was analyzed quantitatively descriptively. The research results prove that there is microplastic contamination in all pond water samples (K1, K2, K3, K4, K5, K6) and "krosok" salt particles (GK) with a total abundance of fragments (70 particles/g), fiber (46 particles/g) and film (36 particles/g).

Abstract

Ikan tongkol (Euthynnus affinis) merupakan inang bagi berbagai jenis parasit metazoa, yaitu parasit monogenea, digenea, acantocephala dan nematoda. Anisakis sp. merupakan parasit dari kelompok nematoda, yaitu penyebab penyakit yang mempunyai hubungan dengan inangnya. Tujuan penelitian ini adalah menentukan prevalensi dan derajat infeksi kontaminasi parasit Anisakis sp. pada ikan tongkol yang didaratkan di tempat pelelangan ikan (TPI) Kota Oeba-Kupang. Metode penelitian yang digunakan adalah metode deskriptif komparatif. Uji laboratorium digunakan untuk identifikasi dan prevalensi parasit Anisakis sp. mengacu pada SNI 2332.6:2015. Hasil penelitian menunjukkan parasit Anisakis sp. paling banyak ditemukan pada usus ikan tongkol sebanyak 21, hati 17, lambung 13, dan pada gonad sebanyak 7 parasit. Perhitungan prevalensi pada ikan tongkol dari 8 sampel positif terinfeksi parasit Anisakis sp. dengan nilai 20% yang termasuk dalam kategori sering (often). Ikan tongkol yang didaratkan di TPI Oeba-Kota Kupang positif terinfeksi parasit L3 Anisakis sp. tipe I pada 8 dari 40 sampel. Derajat infeksi pada ikan tongkol sebesar 7,25 individu parasit per ikan yang termasuk kategori rendah.

Abstract

Ecosystem-based marketing strategy in tuna fisheries management that focuses on implementing sustainability principles in marketing and managing fisheries resources. This research aims to identify effective strategies for marketing tuna products by considering ecological and social impacts, as well as ensuring the long-term sustainability of fisheries resources. The method used in this research involved analysis of primary and secondary data, which included interviews with key stakeholders in the tuna fishing industry and analysis of related literature. Research findings show that integrating marketing strategies with an ecosystem-based approach can increase the added value of tuna products, expand market access, and support conservation efforts. In conclusion, implementing an ecosystem-based marketing strategy not only supports environmental sustainability but also provides economic benefits for fishing industry players. Therefore, this approach is recommended as a model for developing a more sustainable fishing industry in the future
