Abstract

ABSTRAK Dendeng ikan dapat terkontaminasi oleh berbagai spesies kapang kontaminan. Dendeng ikan merupakan salah satu produk olahan ikan yang banyak disukai oleh masyarakat dan banyak diproduksi sebagai industri rumah tangga dalam rangka diversifikasi produk ikan. Apabila spesies-spesies kapang kontaminan dapat menghasilkan mikotoksin, maka dapat membahayakan kesehatan para konsumen dendeng Ikan. Penelitian ini bertujuan untuk: 1) meneliti spesies-spesies kapang kontaminan yang dapat bertahan hidup pada ikan yang telah diawetkan menjadi dendeng ikan 2) mengetahui jumlah koloni tiap spesies kapang kontaminan pada dendeng ikan; 3) mengetahui spesies kapang kontaminan yang paling dominan pada dendeng ikan. Sampel dendeng Ikan dibuat dengan menggunakan bahan baku ikan kembung lelaki (Rastreiliger canagurta). Dendeng ikan disimpan dalam suhu ruang selama 1-3 hari. Sampel dendeng ikan yang telah disimpan selama 6x24 jam sebanyak 10 gram dihaluskan dan dilarutkan dalam 90 ml larutan air pepton 0,1%, sehingga diperoleh suspensi dengan tingkat pengenceran 10-1 kemudian suspensi diencerkan lagi dalam larutan air pepton 0.1% pada tingkat pengenceran 10-2, 10-3, 10-4, 10-5, 10-6. Suspensi pada masing-masing tingkat pengenceran dinokulasikan pada medium Czapek’s Agar sebanyak 0,1 ml dan diinkubasikan pada suhu 25°C selama 7x24 jam. Selanjutnya dilakukan penghitungan jumlah koloni tiap spesies kapang kontaminan, isolasi tiap spesies kapang kontaminan, pengamatan morfologi koloni, deskripsi ciri-ciri mikroskopis, serta identifikasi tiap spesies kapang kontaminan. Hasil penelitian ini menunjukan bahwa, 1) Dalam sampel dendeng ikan yang diperiksa ditemukan 5 genus yang meliputi 17 spesies kapang. Kelima genus kapang tersebut ialah Aspergillus, Peniciilium. Fusarium, Cladosporium, dan Genicularia 2) Jumlah koloni tiap spesies kapang kontaminan pada dendeng ikan berkisar antara 0,13x104 cfu/g sampai 3,20x107 cfu/g sampel; 3) Spesies kapang kontaminan yang paling dominan pada dendeng ikan ialah Penicilium paraherquei yang berjumlah 3,20x10 cfu/gram sampel. Sehubungan dengan hal tersebut, maka keberadaan speies-spesies kapang kontaminan pada dendeng ikan perlu mendapat perhatian agar dendeng ikan tetap aman untuk dikonsumsi.   Kata kunci: Kapang kontaminan, dendeng ikan, mikoflor

Abstract

Teknik dasar yang harus dikuasi pada saat melaksanakan penelitian secara molekuler adalah isolasi DNA genom. Isolasi DNA bertujuan untuk memisahkan DNA dari komponen lainnya seperti lipid, protein, dan polisakarida. Secara umum, tahapan isolasi DNA untuk berbagai bahan adalah sebagai berikut : lisis sel atau jaringan yang efektif, denaturasi kompleks nukleoprotein, dan inaktivasi nuklease. Akan tetapi bahan yang berbeda akan membutuhkan metode yang berbeda juga. Salah satu jaringan yang sulit untuk dilakukan isolasi DNA adalah jaringan hewan.Jaringan hewan memiliki lemak dan protein yang sangat banyak sehingga dapat mengkontaminasi DNA itu sendiri.Tahapan lisis adalah tahapan penting yang mempengaruhi kesuksesan isolasi DNA hewan. Terdapat berbagai macam cara yang dapat dilakukan untuk melisiskan sel dan jaringan. Pada penelitian ini dilakukan perbandingan proses lisis dengan 4 perlakuan yang berbeda yakni lisis dengan menggunakan teknik Sambrook (1987) dimana jaringan di inkubasi dengan suhu 55 oC selama 12 jam, lisis dengan dengan metode Penggerusan yakni menggunakan mortar dan prestel, lisis dengan suhu 65 oC dalam inkubasi selama 2 jam, dan lisis dengan suhu 80 oC dalam inkubasi selama 10 menit. Setelah tahapan lisis selesai, ke empat perlakuan di ekstraksi dengan metode organik (Phenol Chlorofom Isoamyl Alcohol25 : 24 : 1), DNA kemudian cuci dengan menggunakan ETOH 70% dan pelet DNA dilarutkan dengan menggunakan buffer TE. Hasil menunjukkan bahwa teknik Sambrook menunjukkan hasil yang lebih baik, berikutnya metode inkubasi 65 derajat selama 2 jam yang menunjukkan hasil baik, sementara metode lisis dengan mortar dan prestel, maupun dengan inkubasi 80 derajat selama 10 menit tidak menunjukkan hasi yang baik akibat terjadi kerusakan DNA.
