Smoked fish is traditionally processed by fish through an open process of hot smoked. Smoked fish process in Indonesia, especially in Maluku, is still carried out traditionally with capital and small business scale so that the use of tools is still simple, besides the sanitation and hygiene of handling and processing are still low. The raw material used in this study is smoke tuna loin produced by Dusun Air Manis,Laha village. This study aims to determine the microbiological and chemical quality of the smoked fish that was produced from Dusun Air Manis, Laha village. The test parameters carried out consisted of microbiological tests: 1) Total microbes on frozen tuna loin, washing water, immersion water, bamboo, smoked racks and smoked tuna, 2) Escherichia coli test on frozen tuna loin, washing water, soaking water, smoked tuna, 3) Salmonella test on smoked tuna. Chemical analysis of smoked tuna included moisture and pH. The results showed that the total plate count (TPC), Escherichia coli and Salmonella on tuna loin smoke still met microbiological standards according to SNI 2725: 2013. Moisture of smoked tuna was 59% and still meets the quality standard according to SNI 2725: 2013 which is a maximum of 60%. The pH of smoked tuna was 5.8.
Hasil perikanan merupakan produk yang mudah mengalami kebusukan, sehingga diperlukan teknik penanganan yang cermat dan tepat untuk mempertahankan mutunya. Penelitian ini bertujuan untuk membuktikan dampak penanganan ikan layang yang dijual di pasar. Ikan layang diambil secara acak di Pasar Arumbae dan Pasar Batu Merah Kota Ambon dua kali dalam sehari yakni pada waktu pagi dan waktu sore hari. Teknik penanganan ikan diamati pada saat distribusi dan penanganan di pasar yang meliputi pembersihan, penyimpanan, peletakan ikan serta pemberian es. Jumlah cemaran mikroba pada sampel dihitung menggunakan metode total plate count (TPC). Hasil penelitian menunjukkan bahwa jumlah cemaran mikroba pada ikan yang diambil pada pagi hari lebih rendah dibandingkan pada ikan yang diambil pada sore hari. Teknik penanganan dan penjajakan ikan layang yang diterapkan oleh para pedagang di Pasar Arumbae dan Batu Merah belum diterapkan dengan baik dan belum memperhatikan sistem rantai dingin, sanitasi air, dan tempat penyimpanan ikan selama penjualan. Jumlah cemaran mikroba pada ikan layang segar di Pasar Arumbae dan Pasar Batu Merah pada pagi hari yakni 1,2x10⁴-2,6x104 CFU/g dan 1,5x104-2,6x104 CFU/g sedangkan pada sore hari yaitu 2,4x10⁴-5,0x105 CFU/g dan 4,9x104-4,6x105 CFU/g. Jumlah mikroba pada ikan layang segar di pasar tradisional Kota Ambon masih sesuai standar mutu mikrobiologi ikan segar yaitu maksimal 5x10⁵ CFU/g.
Fish processing industry produces more than 60% of byproducts include the head, bones, fins, skin, viscera and roes. Only 40% of the total body of fish that can be consumed by humans. Byproduct of the fishing industry is a source of nutrition and functional food ingredients, such as roes have a high protein content and amino acids. The aim of this study was determine the chemical composition and amino acid profile of dolphin fish roe. The proximate composition of dolphin fish roe is protein 19.16%, fat 2.05%, moisture 72.94%, ash 1.12% and 4.72 carbohydrates. There are 17 amino acids in dolphin fish roe including proline (3.32%), arginine (3.01%), serine (2.85%) and phenilalanine (2.65 %) while the smallest amino acid is cystine (0.43%), histidine (1.22%) valine (1.34%) and methionine (1.36%).
This study aims to determine the proximate and total bacterial of dry salted scad fish (Decapterus sp.)dried using a closed solar drying sistem. The research method begins with fish weed in ‘butterfly’ thenwashed using flowed water and immersed in 15% salt solution for 30 minutes. The drying method was aclosed sun drying cabinet sistem, with 3 drying racks named Rack 1, Rack 2 and Rack 3 starting from thebottom. The dried salted fish was analyzed its proximate consisting of moisture content, ash content, fatcontent and protein content, as well as bacterial tests using Total Plate Count (TPC). The results showedthat the proximate values on Rack 1, Rak2, and Rack 3 were water content of 25.58%, 20.39%, and17.80% respectively; ash content of 9.64%, 9.69% and 7.71% respectively, fat content 8.08%, 11.40%and 15.16%, respectively and protein content 53.73%, 58.10%, and 59.11%. respectively. Meanwhile,the total plate count (TPC) value of dried salted layang fish (Decapterus sp) on Rack 1, Rak2, and Rack 3was 2.73 log x CFU / g or 5.4 x 102 CFU / g, 2.74. logx CFU / g or 5.5 x 102 CFU / g, and 2.74 logx CFU / gror 5.9 x 102 CFU / gr, respectively. The best place to put fish in the dryer is on Rack 3 as this is indicatedby the low moisture content. The TPC value was still within the value limit required by the SNI.
