Abstract

The study of fish nugget snike (Awaous melanocephalus) with the substitution of tempe has beendone. Four formulations of nike and tempe ratio were observe, i.eformula A1 (100% nike: 0% tempe) A2(75% nike: 25% tempe), A3(50% of nike: 50% tempe), and A4 (25% of nike: 75% tempe). Organoleptic assesment was done to obtain the most preferred formula. Assesment on the effect of tempe to the shelf life of nugget, where also conducted. Quality parameter estimated were TPC, TBA, TVBN, and pH. Data were analyzed using a completely randomized design, faktorial 4x3 dan 3x ulangan, treatments was test educing Annovawith 0.05, for significant effect testedusing Duncan's multiple rangetest (DMRT). The result showed that the most preferred formulation by the panel ists wasthe formula A2. The longest shelf life was the formula A4, which up to 20 days of storage. TBA value also shown the same results as of TPC, the lowest TBA(0057 mg malonaldehid/100 g samples) until 20 days of storage

Abstract

Research on the mercury (Hg) content in oilfish (Ruvettus pretiosus) and escolar (Lepidocybium flavobrunneum) has been carried out, which aims to examine and assess the quality of the fish based on Hg content. Measurement of Hg performed using the analysis procedures in accordance with the Indonesian National Standard (SNI 01-2354-2006). The results showed that Hg measured in all fish samples in which its amount varies based on the size and place, and is influenced by the size (weight) of the sample. Furthermore, it can be concluded that the smaller the size of the fish sampled, then the lower the content of Hg, and the size (weight) >11 kg, the two types of fish that have bad quality where it is not safe for consumption, because it contains Hg higher than the safety limit set by the Government of Indonesia (0.5 ppm). Penelitian tentang kandungan merkuri (Hg) pada ikan oilfish (Ruvettus pretiosus) dan escolar (Lepidocybium flavobrunneum) telah dilakukan, yang bertujuan untuk menelaah dan menilai mutu kedua jenis ikan tersebut terhadap kandungan Hg. Pengukuran Hg dilakukan menggunakan prosedur analisis sesuai dengan Standar Nasional Indonesia (SNI 01-2354-2006). Hasil penelitian menunjukkan bahwa Hg terukur pada semua sampel ikan di mana jumlahnya bervariasi berdasarkan ukuran dan tempat, serta dipengaruhi oleh ukuran (berat) sampel. Selanjutnya dapat disimpulkan bahwa semakin kecil ukuran ikan sampel, maka makin rendah kandungan Hg, dan pada ukuran (berat) >11 kg, kedua jenis ikan tersebut memiliki mutu yang tidak baik di mana tidak aman untuk dikonsumsi, karena memiliki kandungan Hg lebih tinggi dari batas aman yang ditetapkan oleh Pemerintah Indonesia (0,5 ppm).

Abstract

This research aims to determine the effect of Caulerpa racemosa seaweed extract-ice to the quality of scad fish  (Decapterus spp.). The quality was measured by Total Volatile Bases (TVB-N), pH, and Total Plate Count (TPC), using 2 (two) treatments: seaweed extract concentration ( 75%, 50%, 25%, and 0%) and storage time (0, 5, 10, 15, and 20 days). The results showed that the TVB-N values ranged from 28.98 mg N/100 g (extract conc. 75%) to 34.34 mg N/100 g (extract conc. 0%) for the 20 days. The highest pH values for 20 days were obtained by concentration  0% i.e. 6.39, followed by 50% (6.34), 25% (6.31) and 75% (6.25). The highest TPC value at the 20th day was 8.1 x 106 cfu/g for 0% and the lowest was 3.1 x 103 cfu/g for 75%. Analysis of variance showed that the interaction of Caulerpa racemosa seaweed extract ice concentration and storage time has a significant effect on TVB-N, pH, and TPC value of scad fish. Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan es ekstrak rumput laut Caulerpa racemosa terhadap mutu ikan layang (Decapterus sp.), melalui uji Total Volatile Base (TVB-N), pH, dan Total Plate Count (TPC) dengan menggunakan dua perlakuan yaitu persentase ekstrak rumput laut (A): 75%, 50%, 25%, 0% dan lama penyimpanan (B): 0 hari, 5 hari, 10 hari, 15 hari, dan 20 hari. Nilai TVB-N berkisar antara 28,98 mg N/100 g (75%) sampai 34,34 mg N/100 g (0%) pada hari ke-20. Nilai pH tertinggi pada hari ke-20 diperoleh dengan perlakuan es ekstrak rumput laut 0% yaitu 6,39, diikuti dengan perlakuan 50% (6,34), 25% (6,31), dan 75% (6,25). Nilai TPC ikan layang tertinggi pada hari ke-20 adalah 8,1 x 106 cfu/g dengan perlakuan 0% es ekstrak rumput laut dan terendah yaitu 3,1 x 103 cfu/g pada perlakuan es ekstrak rumput laut 75%. Analisis sidik ragam memperlihatkan bahwa nilai TVB-N, pH, dan TPC menggunakan persentase es ekstrak rumput laut dan lama penyimpanan serta interaksi antara keduanya memberikan pengaruh yang sangat nyata.
