      Abstract
      Dadih adalah produk susu fermentasi tradisional yang berasal dari Sumatera Barat, yang diproduksi melalui fermentasi alami susu kerbau dalam tabung bambu. Selama proses fermentasi dadih, bakteri asam laktat (BAL) mendominasi proses proteolisis. Sementara itu sudah banyak penelitian yang dilakukan pada bioaktivitas peptida namun, penelitian masih terbatas mengenai sifat antikanker yang dimilikinya. Penelitian ini bertujuan untuk menganalisis sifat antikanker pada dadih dengan dan tanpa filtrasi dadih terhadap sel kanker MCF-7. Sampel dadih didapatkan dari penjual komersial dari Kota Padang. Filtrasi dilakukan dengan menggunakan filtrasi Amicon dengan 3000 MWCO. Konsentrasi protein dari dadih dengan dan tanpa filtrasi diuji dengan menggunakan metode Lowry yang menunjukkan bahwa dadih yang di filtrasi memiliki konsentrasi protein yang lebih sedikit dibandingkan dengan dadih non filtrasi. Selanjutnya, aktivitas antikanker pada dadih dilakukan secara in vitro dengan MTT Assay yang menunjukkan bahwa nilai IC50 dari kedua sampel dianggap sebagai antikanker yang kuat. Tetapi, dadih non filtrasi menunjukkan aktivitas penghambatan yang lebih baik dibandingkan dengan dadih yang di filtrasi berdasarkan nilai IC50.
       
      Dadih is a traditional fermented milk product originating from West Sumatra, produced through the natural fermentation of buffalo milk within bamboo tubes. During fermentation, lactic acid bacteria (LAB) dominated the process by not only producing lactic acid, but also peptides from proteolysis process. While many studies were conducted on bioactivity of these peptides, limited studies were conducted on their anticancer properties. This study aimed to analyze the anticancer properties of dadih with and without peptide filtration against MCF-7 cancer cells. Dadih samples will be collected from commercial vendors in Padang. Filtration was done using Amicon filtration with 3000 MWCO. Concentration of protein from unfiltered and filtered dadih were tasted using Lowry method which indicated that filtered dadih has significant less protein as compared to non-filtered dadih. Further, anticancer activity was also done in vitro with MTT Assay which indicated that IC50 value of both samples were considered to be strong anticancer. But the non-filtered dadih exhibited better inhibition activity as compared to filtered one based on their IC50 values.
