      Abstract
      The objective of this research was to observe the effect of antimicrobial substrate of Lactobacillus plantarum 1A5 origin as a natural preservative on beef meatball at room temperature storage. The complete randomized design of two factors was used to analyze the effect of antimicrobial substrate microbiological characteristics of beef meatball. The treatments and control were storage at room temperature (± 280 C) with antimicrobial substrat 100 % and 0 % for 0 hour, 9 hours, and 18 hours after conditioning process. The variables were total plate count, quantitative of Staphylococcus aureus, quantitative of Escherichia coli and qualitative of Salmonella spp. The result of this research showed that there were decreasing (P<0,05) of total microbe, quantitave of Staphylococcus aureus and quantitative of Escherichia coli were decreasing (P<0,05) during room storage until 9 hours. Salmonella spp. test showed negative result.
       
      Daging merupakan pangan sumber protein hewani yang memiliki kandungan nutrisi lengkap terutama komposisi proteinnya. Diversifikasi dari produk daging salah satunya adalah dengan dibuat bakso. Daging memiliki karakteristik mudah rusak (perishable) oleh aktivitas mikroorganisme. Salah satu cara yang biasa digunakan oleh produsen bakso untuk memperpanjang umur simpan adalah dengan penambahan bahan pengawet berbahaya untuk kesehatan seperti formalin dan boraks. Konsumen sekarang sudah cenderung untuk lebih memilih produk makanan yang berpengawet alami yang tidak menimbulkan masalah kesehatan. Bahan pengawet ini berasal dari salah satu bakteri asam laktat. Bakteri asam laktat mampu menghasilkan asam laktat, hidrogen peroksida dan hasil metabolisme lain yang dapat memberikan pengaruh positif bagi yang mengonsumsi.
