      Abstract
      Pemanfaatan pakan pada ternak ruminansia sering terkendala oleh rendahnya degradasi serat di dalam rumen. Penelitian ini bertujuan mengevaluasi pengaruh inokulasi mikroba selulolitik dan suplementasi rumput laut terhadap kecernaan nutrien, populasi mikroba, dan profil metagenom bakteri rumen secara in vitro. Penelitian menggunakan rancangan acak kelompok dengan tiga perlakuan dan lima kelompok, yaitu kontrol, inokulasi mikroba selulolitik, serta kombinasi inokulasi mikroba selulolitik dengan 2% Ulva lactuca dan 2% Gracilaria verrucosa. Perlakuan berpengaruh nyata (P<0,05) terhadap populasi protozoa serta kecernaan NDF, ADF, dan selulosa, serta berpengaruh sangat nyata (P<0,01) terhadap KCBK dan KCBO. Penambahan rumput laut meningkatkan kecernaan NDF, namun belum optimal meningkatkan KCBK dan KCBO. Analisis metagenom menunjukkan keberadaan bakteri pendegradasi serat pada seluruh perlakuan. Dapat disimpulkan inokulasi mikroba selulolitik berpotensi meningkatkan pemanfaatan pakan berserat melalui perubahan komunitas mikroba rumen.
       
      The utilization of fibrous feed in ruminants is often constrained by low fiber degradation in the rumen. This study evaluated the effects of cellulolytic microbial inoculation and seaweed supplementation on nutrient digestibility and the rumen bacterial metagenome in vitro. A randomized block design with three treatments and five blocks was applied: control, cellulolytic microbial inoculation, and inoculation combined with 2% Ulva lactuca and 2% Gracilaria verrucosa. Treatments significantly affected (P<0.05) protozoal population and the digestibility of NDF. ADF. and cellulose. while dry and organic matter digestibility were highly affected (P<0.01). Seaweed supplementation improved NDF digestibility but showed limited effects on dry and organic matter digestibility. Metagenomic analysis revealed fiber-degrading bacteria in all treatments. Overall, cellulolytic microbial inoculation may enhance fibrous feed utilization by modifying the rumen microbial community.
