Abstract

Squid is a fishery commodity that has high nutritional content. Squid ink is squid waste that has not been used optimally. The purpose of this study was to determine the chemical and organoleptic characteristics of squid ink flavoring using oven drying method. The ingredients used are squid ink and other complementary spices. The results showed that the organoleptic characteristics of the squid ink flavoring using the oven drying method had a value of appearance of 7.37 (preferred), smell of 7.12 (preferred), taste of 7.07 (preferred) and texture of 6.06 (somewhat preferred). The squid ink flavoring with the drying method was preferred by the panelists. In addition, the nutritional content of squid ink flavoring using the oven drying method is 23.15% water content and 33.53% protein content.

Abstract

Kota Bitung merupakan salah satu sentra industri perikanan di Indonesia, utamanya produk olahan tuna seperti loin beku, steak, cube, saku, dan lainnya. Berkembangnya industri pengolahan ini membutuhkan perhatian dan pengendalian serius terhadap mutu dan keamanan pangan. Tujuan penelitian yaitu untuk mengetahui kajian mutu dan keamanan pangan produk tuna loin beku. Penelitian ini dilaksanakan bulan April – Mei 2024 bertempat di salah satu Unit Pengolahan Ikan (UPI) Kota Bitung, menggunakan metode deskriptif kualitatif pada pengamatan alur proses termasuk penerapan sanitasi dan hygiene dan pengujian mutu. Hasil penelitian menunjukkan bahwa terdapat 23 alur proses pengolahan tuna loin beku yang disesuaikan dengan SNI 4104:2015 dengan menerapkan program keamanan pangan melalui penerapan GMP dan SSOP. Penanganan secara cepat, cermat, dan saniter dalam menjaga rantai dingin dilakukan di setiap alur proses. Suhu pusat produk selalu dipastikan berada di bawah 4,40 C guna mencegah pertumbuhan mikroba. Hasil uji organoleptik pada bahan baku dan produk akhir telah memenuhi persyaratan yaitu 8 untuk bahan baku dan 9 untuk produk akhir. Cemaran mikroba pada bahan dan produk akhir telah memenuhi SNI 4104:2015. Histamin pada produk akhir sebesar 1,52 ppm masih berada pada batas aman, serta penerapan suhu produk, ruangan, dan media air telah sesuai standar. Rendemen yang dihasilkan pada saat loinning, skinning, dan final trimming yaitu 80,37%, 67,77%, dan 56,77%. UPI telah menerapkan pengendalian mutu sehingga produk tuna loin beku terjamin keamanan pangannya.

Abstract

This study aims to evaluate the nutritional and microbiological profiles of fermented skipjack tuna (Katsuwonus pelamis) entrails silage based on variations in molasses addition as a candidate for value-added feed ingredients. The study was conducted from September to November 2025 at the Processing Workshop of the Bitung Marine and Fisheries Polytechnic. The skipjack tuna entrails raw material was fermented for 14 days using probiotics as a source of Lactic Acid Bacteria (LAB) with molasses added at levels of 10%, 20%, and 30%. The parameters tested included crude protein, crude fat, Total Plate Count (TPC), total LAB, and the presence of Salmonella. The results showed that increasing the molasses level tended to decrease the protein content and produced variations in crude fat values in the silage product. Microbiological activity showed that LAB was higher in the 30% molasses treatment, while TPC was relatively stable in all treatments. All samples were declared safe for because they were Salmonella-negative. Overall, fermented skipjack tuna entrails silage with a molasses level of 10% provided a more optimal nutritional and microbiological profile than other treatments, making it a potential candidate for value-added feed ingredients in supporting the sustainable utilization of fishery waste
