Kajian Potensi Pemanfaatan Limbah Sisik Ikan Dari Usaha Ikan Tangkap Laut (Studi Kasus Pasar Kota Bengkulu)

Abstract

The potential utilization of fish by-products from fishery processing businesses in the form of fish scales can still be utilized for various synthetic products. Fish scales contain 29.8 – 40.9% protein; fat content 0.1-1%, mineral content 30.0-36.8%, collagen 37.5%, with the content of these protein compounds, fish scales can produce active compounds such as chitosan, collagen and gelatin. Bengkulu City is an area that has a major contribution to the province Bengkulu, with a total production of 46,145 tons of marine catch per year (KKP, 2020). This research aims to determine the potential of fish scales produced from fish processing activities in Bengkulu City based on the yield of fish scales per total weight of fish. Snapper, grouper and pomfret are the three types of marine capture fisheries could produce the highest production volume in Bengkulu City. Based on the research conducted, it was found that the yield of snapper scales resulted in the highest yield of fish scales, was 5.2% per total weight, with the results of the yield, it was known that fish scales could be utilized and potentially reprocessed into new products. The results of interviews with fish processing entrepreneurs in one of the largest markets in Bengkulu City (Panorama Market), it is known that every day the fishery product processing can produce 20-50 kg of snapper, so if this related to the yield of fish scales with the amount of fish production, it is known that Snapper scales have high potential to be used to provide additional income for fisheries entrepreneurs. The fish scale waste obtained can be reprocessed into useful products such as gelatin, chitosan, and collagen. Gelatin is used as a food additive, chitosan is used as a natural preservative, and collagen is used as an additive in food or pharmaceutical products.

Edukasi Pemanfaatan Limbah Hasil Perikanan Pada Kelompok PKK Di Negeri Passo Kecamatan Baguala, Kota Ambon

“…Pengelolaan limbah yang ramah lingkungan merupakan solusi yang baik sehingga limbah tersebut dapat dimanfaatkan lebih lanjut. Umumnya, limbah hasil perikanan terdiri dari limbah cair berupa darah, lendir dan lemak sedangkan limbah padat berupa tulang, kepala, insang, sirip, kulit, sisik dan isi perut (Ifa et al, 2018); (Elvina & Utami, 2022).…”

“…Menurut (Katun et al, 2015) secara kimia limbah padat tuna loin memiliki kadar air berkisar 78,34-78,78%, protein 14,32-16,41%, lemak 1,56-1,66%, abu 5,18-5,58% dan karbohidrat 1,29-1,34%. Beberapa hasil penelitian menyebutkan bahwa limbah berupa kepala, tulang, isi perut dapat diolah menjadi tepung sebagai bahan baku untuk pakan ternak (Indrastuti et al, 2022), daging merah dan tetelan dijadikan bahan baku produk diversifikasi (Katun et al, 2015), kulit ikan dapat dijadikan kerupuk (Indrastuti et al, 2022), sisik dijadikan bahan baku farmastika seperti kolagen, gelatin dan kitin kitosan (Talumepa et al, 2016); (Ifa et al, 2018); (Elvina & Utami, 2022), dijadikan lem (Sari et al, 2017); (Mariani et al, 2020) atau bahan kerajinan souvenir (Ifa et al, 2018); (Arina et al, 2019).…”
