Abstract

Fish sauce is one of fish-based processed food or fishery product from fermentation process. The appearance of fish sauce is clear brown liquid and it has unique taste and flavor so many people use this as addition ingredient or spices in food to increase its taste. In this study fish sauce was made from petek fish (Leiognathus splendens) that has slow economic value and has not been used optimally. Pineapple was also added as source of bromelin enzyme. This study consisted of two phases which were pilot study and main study. In pilot study fish sauce was made by adding tempe concentration from 10%, 20%, and 30%. Then organoleptic test was done to determine the best fish sauce. The result showed that the most favorablefish sauce was made by adding 10% of tempe concentration. The characteristics of this product were as follows: the color of fish sauce was yellowish brown, its flavor was almost smelled like tempe, its taste was almost salty and its appearance was clear. In main study, tempe concentration was reduced to 5%, 10% and 15%. Organoleptic test showed that the best product was petek fish sauce by adding 15% tempe concentration. The characteristics of this fish sauce were: its color was yellowish brown, its flavor was almost smelled like tempe, its taste was almost tasty and its appearance is clear. The best petek fish sauce had 72,34% water concentration, 6,40% protein, 20,67% ash, 0,36% fat and 0,23% carbohydrate.Keywords: enzyme fermentation, fish sauce, organoleptic test, petek fish, tempe

Abstract

Bekasam is one of the fishery product fermentation by using lactic acid bacteria. Bekasam is still made traditionally by applying spontaneous fermentation that cause product’s quality inconsistent. This research aims to analyze bacteria characteristics that isolated from bekasam and predict its types based on morphology and physiology characteristics. This research consists of three steps which are material analysis, isolation, and bacteria characterization. The result of this characterization is used to predict the bacteria type based on identification key. In this research milkfish bekasam is from traditional fishery product (pengolah) in Indramayu. It is predicted that milkfish has been fermented for two (2) weeks so that bekasam can be obtained. The analysis results shows that milkfish bekasam has Na Cl concentration 3.26 %, pH 4.46 and lactic acid total 1.30 %. Bacteria isolation from bekasam is chosen 5 (five) colony which grows dominantly and have different morphology. Those colony are isolated several times  by quadrant scratch methode by using MRSA media until the pure culture can be obtained. The isolate are characterized based on morphology and physiology characteristic. Based onthe characterization result, it is predicted that isolate B1, B3, and B5 are bacteria Staphylococcus sp., isolate B2 is Erysipelothrix or Lactobacillus, and isolate B4 is family of Streptococcacea which are Streptococcus sp. or Gemella.Key words : characterization, fermentation, isolation, lactic acid bacteria, milkfish(Chanos chanos) bekasam

Abstract

Ikan merupakan salah satu sumber protein hewani yang sangat potensial untuk memenuhi kebutuhan protein. Tetapi sifatnya yang mudah rusak menyebabkan ikan kurang diminati masyarakat, untuk itu perlu diupayakan pengolahan daging ikan menjadi produk yang dapat tahan lama. Salah satu produk olahan daging ikan adalah bakso yang disinggahi menggunakan pengawet sintetik. Oleh karena itu dilakukan usaha untuk mencari alternatif pengganti bahan pengawet sintetik dengan bahan pengawet alami yaitu kitosan dan karagenan. Penggunaan sodium tripolifosfat (STPP) dalam pembuatan bakso sudah dibatasi. Oleh karena itu perlu dilakukan usaha untuk mengurangi penggunaan bahan kimia dan menggantinya dengan bahan alami yaitu karagenan. Konsentrasi kitosan yang digunakan yaitu 0%; 0,1% sedangkan konsentrasi karaginan yang digunakan yaitu 0%; 0,5% dan 1%. Perlakuan dengan konsentrasi kitosan 0,1% dan karagenan 0,5% lebih unggul dalam membentuk gel dan daya awet dengan dibandingkan perlakuan penambahan STPP 15%. Perlakuan tersebut umumnya memiliki nilai rata-rata lebih tinggi dibandingkan perlakuan penambahan STPP 0,15%. Analisis mikrobiologi bakso ikan yang dihasilkan masih di bawah SNI 01-3819-1995 selama penyimpanan 3 minggu pada suhu dingin, dan 8 minggu pada suhu beku. Nilai pH bakso ikan pada perlakuan ini selama penyimpanan suhu dingin dan beku mengalami penurunan (semakin asam).Kata kunci: bakso, karagenan, kitosan, kurisi

Abstract

Air merupakan sumber daya alam yang sangat penting dalam kehidupan manusia dan digunakan untuk berbagai kegiatan, termasuk kegiatan pertanian, perikanan, peternakan, industri, pertambangan, rekreasi, olah raga dan sebagainya. Masalah utama sumber daya air meliputi kuantitas air yang sudah tidak mampu memenuhi kebutuhan manusia yang terus meningkat dan kualitas air untuk keperluan domestik terus menurun khususnya untuk air minum. Tujuan dari penelitian ini adalah mengetahui kemampuan kitosan dalam menurunkan jumlah bakteri koliform dan konsentrasi besi di dalam air sumur dan untuk mengetahui kemampuan kitosan didalam proses pemurnian air sumur. Penelitian ini dilakukan dalam dua tahap, yaitu koagulasi dan filtrasi. Pada proses penjernihan air sumur, didapatkan hasil bahwa penurunan nilai TPC (Total Plate Count) dan konsentrasi besi yang signifikan bila dibandingkan dengan kontrol (tanpa kitosan) adalah larutan kitosan 1 ppm, dimana nilai TPC air sumur sebesar 5,6 x 103 cfu/ml dan nilai konsentrasi besi yaitu 0,08 mg/l. Pada proses filtrasi (tahap akhir), didapatkan hasil bahwa filter dengan kitosan 5 gram sudah dapat menghasilkan air dengan kualitas memenuhi syarat kesehatan, dilihat dari parameter pH, kekeruhan, kadar besi, dan bakteri koliform. Dengan nilai pH sebesar 6,7+0,01, nilai kekeruhan sebesar 4,5+0,71 NTU, kadar besi < 0,016 mg/l, dan nilai bakteri koliform 0 MPN/ml. Parameter TSS hasil pemurnian belum termasuk ke dalam air dengan kualitas memenuhi syarat kesehatan (Raini 2004). Berarti parameter TSS masih perlu diturunkan.Kata kunci: air murni, absorbsi, kitosan, koagulasi, filtrasi.

Abstract

Ikan cucut merupakan ikan yang potensi produksinya cukup tinggi namun pemanfaatannya belum optimal. Terbatasnya pemanfaatan daging ikan cucut karena adanya sejumlah urea pada daging yang mudah terurai menjadi amoniak dan menimbulkan bau pesing, sehingga ikan ini kurang disukai konsumen. Pengurangan kadar urea pada daging dapat dilakukan dengan berbagai cara, salah satunya dengan menggunakan bahan alami, antara lain taoge yang didalamnya terdapat kandungan saponin. Penelitian ini bertujuan untuk mengetahui efektivitas filtrat taoge dalam mereduksi kadar urea ikan cucut. Perlakuan yang digunakan adalah perendaman potongan daging ikan cucut pada filtrat taoge 20 ml, 40 ml, 60 ml, 80 ml, dan 100 ml dengan waktu perendaman 1, 2 dan 3 jam. Hasil penelitian menunjukkan bahwa filtrat taoge dapat digunakan untuk mereduksi kadar urea ikan cucut. Semakin tinggi volume perendam dan makin lama waktu perendaman kadar urea yang tereduksi semakin meningkat.Kata kunci: ikan cucut, saponin, taoge
