      Abstract
      Maggot (Hermetia illucens) merupakan insekta yang berpotensi dijadikan sebagai probiotik karena memiliki kandungan antimicrobial peptide (AMP) yang mampu menghambat pertumbuhan bakteri patogen pada saluran pencernaan inang. Masa simpan merupakan hal yang harus diperhatikan supaya menjaga kualitas suatu produk. Penelitian ini bertujuan menganalisis viabilitas probiotik fermentasi maggot yang diberi pengaruh lingkungan khususnya suhu dan lama waktu penyimpanan. Penelitian ini menggunakan 48 sampel probiotik fermentasi maggot, terdiri dari 12 perlakuan dan 4 ulangan yang dianalisis menggunakan Rancangan Acak Lengkap (RAL) pola faktorial yang terdiri dari 2 faktor. Faktor I merupakan perlakuan lama waktu penyimpanan dengan taraf B1: bulan ke-1, B2: bulan ke-2, dan B3: bulan ke-3. Faktor II merupakan suhu penyimpanan dengan taraf yaitu S1: 4°C, S2: 28°C, S3: 38°C, dan S4: 48°C. Parameter yang diamati yaitu kualitas fisik, populasi mikroba, total asam tertitrasi (TAT), dan zona hambat. Hasil penelitian menunjukkan adanya penurunan pada viabilitas probiotik seiring dengan lamanya penyimpanan. Masa simpan bepengaruh pada nilai total asam dan populasi bakteri asam laktat tapi tidak pada populasi mikroba lainnya dan zona hambat.
       
      Maggot (Hermetia illucens) is an insect that has potential to be used as a probiotic because it contains antimicrobial peptide (AMP) which can inhibit the growth of pathogenic bacteria in the digestive tract of the host. Shelf life is something that must be considered to maintain the quality of a product. This study aimed to analyze the viability of maggot probiotics which are influenced by the environment, especially temperature and storage time. This study used 48 maggot probiotic samples, consisting of 12 treatments and 4 replications which were analyzed using a completely randomized design (CRD) factorial pattern consisting of 2 factors. First factor was long storage time treatment with levels B1: 1st month, B2: 2nd month, and B3: 3rd month. Second factor is storage temperature with levels S1: 4°C, S2: 28°C, S3: 38°C, and S4: 48°C. The parameters observed were physical quality, population of microbes, titratable acidity (TA), and antimicrobial activity of maggot probiotics. The results showed that there was a decrease in the viability of probiotics along with the length of storage. Shelf life has an effect on the total acid and lactic acid bacteria, but has no effect on the population of other microbes and antimicrobial activity.
