      Abstract
      Penelitian ini bertujuan untuk menganalisis efektifitas teknologi proteksi pada berbagai sumber asam lemak tak jenuh dalam mencegah proses biohidrogenasi asam lemak tak jenuh dalam sistem rumen. Penelitian dilakukan menggunakan teknik fermentasi secara in vitro dengan Sapi Peranakan Ongol berfistula sebagai donor inokulum cairan rumen. Penelitian dilakukan dengan menggunakan rancangan faktorial dengan faktor A adalah perlakuan proteksi (Tanpa proteksi, Mikroenkapsulasi dan Sabun kalsium) serta faktor B adalah jenis sumber asam lemak tak jenuh yaitu minyak wijen, minyak kanola dan flaxseed. Parameter yang diukur adalah kecernaan bahan kering (KCBK), Kecernaan Bahan Organik (KCBO), dan N-NH3. Hasil penelitian menunjukkan bahwa proteksi asam lemak menggunakan teknologi proteksi dengan mikroenkapsulasi pada ketiga jenis minyak yang diuji nyata meningkatkan (P<0,05) nilai pH rumen, dan konsentrasi amonia rumen dibandingkan dengan metode sabun kalsium. Nilai kecernaan bahan kering dan bahan organik tidak berbeda antar perlakuan. Dapat disimpulkan bahwa poteksi asam lemak tak jenuh dengan mikro enkapsulasi lebih efektif meningkatkan aktifitas fermentasi rumen.
       
      The research was aimed to investigate the effectiveness of several protection strategies on unsaturated fatty acid from plant to prevent from rumen biohydrogenation. This experiment was conducted by using in vitro fermentation technique and used fistulated Ongole Crossbreed as a rumen donor. The design of experiment was a factorial block design with 2 factors i.e. protection strategy (no protection, microencapsulation, Calcium-soap) and source of unsaturated fatty acid (wijen oil, canola oil, flaxseed oil). Ammonia concentration were measured at 4 h incubation, while dry matter and organic matter digestibility, and fatty acid profile were measured at 48 h incubation. The results show that all plant oil (wijen oil, canola oil, flaxseed oil) which protect by using microencapsulation increased (P<0,05) rumen pH, and ammonia concentration. Dry matter and organic matter digestibility did not different among treatments. It was concluded that plant oil protection by using microencapsulation more effective to increase rumen fermentation activity than calcium-soap technology.
