Judul: Effect of E. faecalis probiotics supplementation from Maggot H. illucens on In Vitro Digestibility and rumen Fermentability
Abstrak: Tujuan penelitian ini adalah untuk menguji pengaruh suplementasi probiotik E. faecalis yang berasal dari maggot H. illucens dengan level yang berbeda secara in vitro berdasarkan kecernaan dan fermentabilitasnya dalam rumen. Penelitian ini menggunakan rancangan acak kelompok dengan 3 perlakuan dan 4 ulangan. Perlakuan terdiri dari P0 (tanpa suplementasi probiotik), P1 (suplementasi probiotik 0,5%), dan P2 (suplementasi probiotik 1%). Parameter yang diukur meliputi nilai pH, Ammonia (NH3), VFA(volatile fatty acid) total, VFA parsial, produksi gas metan (CH4), populasi bakteri, populasi protozoa, koefisien cerna bahan kering (KcBK) dan koefisien cerna bahan organik (KcBO). Hasil menunjukkan bahwa setiap perlakuan tidak berpengaruh nyata terhadap nilai pH, Ammonia (NH3), VFA parsial, CH4, populasi bakteri, populasi protozoa, KcBK dan KcBO, namun suplementasi probiotik E. faecalis 0,5% berpengaruh nyata dalam menurunkan nilai VFA total. Berdasarkan hasil penelitian dapat disimpulkan bahwa suplementasi probiotik E. faecalis asal maggot H. illucens pada level 0,5% dan 1 % belum dapat bekerja secara optimal terhadap fermentabilitas dan kecernaan rumen. Suplementasi probiotik E. faecalis pada level 0,5% dan 1% tidak mengganggu aktivitas fermentasi di dalam rumen., The study aimed to examine the effect of supplementation of E. faecalis probiotics from maggot H. illucens with different levels on in vitro digestibility and rumen fermentability. This study used a randomized block design (RBD) with 3 treatments and 4 replicates. The treatments were P0 (diet without probiotic), P1 (diet supplemented with 0.5% probiotics), and P2 (diet supplemented with 1% probiotics). Parameters on this research are pH value, NH3 (ammonia), total VFA (volatile fatty acid), partial VFA, methane gas production (CH4), rumen protozoa population, rumen bacterial population, dry matter digestibility (DMD), and organic matter digestibility (OMD). The results showed that each treatment have no significant effect on pH value, NH3 (ammonia), partial VFA, CH4, rumen protozoa population, rumen bacterial population, dry matter digestibility (DMD), and organic matter digestibility (OMD), but supplementation of 0.5% probiotics E. faecalis had a significant effect on reducing total VFA. It can be concluded that Supplementation of probiotic E. faecalis from maggot H. illucens at the level of 0.5 and 1% has not been able to work optimally on rumen fermentability and digestibility. Supplementation of probiotic E. faecalis at the levels of 0.5% and 1% did not interfere with the fermentation activity in the rumen.

Judul: Efektivitas Pemberian Probiotik Cair pada Taraf Berbeda terhadap Fermentasi dan Kecernaan in vitro Ransum Sapi Potong
Abstrak: The aim of this experiment was to study the effect of liquid probiotic supplementation at different levels on in vitro fermentation and digestibility of beef cattle ration. The fermentability experiment used factorial randomized block design 3x4 with four replicates. Factor A was beef cattle ration without or with liquid probiotic supplementation at different levels: A1=control ration, A2=A1 + 0.1% (vw-1) liquid probiotic, and A3=A1 + 0.2% (vw-1) liquid probiotic. Factor B was incubation periods: 0, 1, 2, and 3 hours. The digestibility experiment used randomized block design with three probiotic treatments (A1, A2, A3) and four replications. The result showed that NH3, total VFA concentrations, bacterial population and digestibility were influenced by liquid probiotic supplementation at different levels. Incubation time influenced pH and those variables except digestibility; however, these treatments did not produce significant effect on degradability, protozoa and microbial protein synthesis. The result of polynomial orthogonal test showed that A3 is the optimal treatment.

Abstrak: Perkembangan kota Jakarta dari waktu ke waktu sangatlah cepat, sehingga menyebabkan kota-kota tua banyak yang tergusur untuk dijadikan daerah baru yang lebih modern. Apabila hal tersebut tidak ditanggulangi secara dini maka keberadaan Kota Lama Jakarta akan hilang. Hal inilah yang melatar belakang untuk dilakukan tindakan perlindungan dan revitalisasi kawasan bersejarah Sunda Kalapa.
