Abstract

Selama ini cara pengawetan ikan tradisonal biasanya dilakukan dengan  pengasapan tetapi saat ini sudah dikembangkan metode pengawetan lain yaitu menggunakan metode pengasapan asap cair. Asap cair yang digunakan dalam penelitian ini adalah asap cair dari “waa sagu” dengan konsentrasi 5% + garam 5% dan direndam selama 10 menit, jenis ikan yang digunakan yakni ikan tuna (Thunus sp). Daging ikan tuna direndam dalam asap cair dan disimpan selama 10 hari pada suhu kamar. Penelitian ini bertujuan untuk untuk mengetahui mutu mikrobiologis (total plate count) ikan tuna asap yang direndam dengan asap cair  “waa sagu” selama penyimpanan suhu kamar.. Hasil analisa total bakteri pada ikan tuna asap masih memenuhi syarat SNI serta aman dan layak untuk dikonsumsi. Asap cair dari “waa sagu” dapat memperpanjang masa simpan ikan tuna selama 10 hari pada suhu kamar. Asap cair mempunyai sifat antibakteri lebih mudah diaplikasikan dan lebih aman dari asap konvensional dan fraksi tar yang mengandung hidrokarbon aromatik telah dipisahkan, sehingga produk asap cair bebas polutean dan karsinogen.

Abstract

The raw materials used for tempe production are highly diverse. In addition to soybeans, tempe can also be produced from seagrass seeds (Enhalus acoroides) using tempe starter culture. To accelerate fermentation, additional starters in the form of rice flour and wheat flour were used. This study aimed to determine the characteristics of tempe made from Enhalus acoroides seeds using rice flour and wheat flour starters in combination with soybean tempe flour. The ratio of soybean tempe flour to wheat flour (A1) and rice flour (A2) was 1:3. The combined starter was added at 20% of the total weight of seagrass seeds. The research employed an experimental method. The parameters analyzed included appearance, taste, aroma, and texture for subjective evaluation, and moisture content, protein, fat, ash, carbohydrate, calcium (Ca), iron (Fe), and lead (Pb) for objective analysis. The results showed that the use of wheat flour and rice flour starters combined with soybean tempe flour produced tempe with varied sensory values and chemical compositions. The sensory evaluation of Enhalus acoroides tempe yielded appearance scores ranging from 3,12 to 3,87 (like to very like), taste scores of 3,18-3,20 (like), aroma scores of 3,0-3,3 (like), and texture scores of 3,7-3,8 (very like). The chemical composition included moisture content ranging from 56,04-59,73%, ash 0,52-0,96%, fat 0,85-1,3%, protein 1,52-2,92%, carbohydrate 35,53-40,63%, calcium (Ca) 0,15-0,77 mg/L, iron (Fe) 8,22-8,73 mg/L, and lead (Pb) 0,002-0,125 mg/L. The use of rice flour starter contributed the most to the sensory characteristics, moisture, fat, protein, and iron content of tempeh, while the wheat flour starter was more dominant in increasing ash, carbohydrate, and calcium levels. The lead (Pb) content was also found to be below the maximum permissible limit, indicating that the tempeh produced in this study is safe for consumption.
