Limitation of feed and low nutrient consumption in dry season cause a longer period of cattle fattening. The problems can be overcome by applying a cheaper and easier technology namely feed conservation technology. Method applied were extension, training, and mentoring. The result showed that the farmers’ participation were very active refers to their present and questiones raised deal with the materials presented. The highly participation also found during the training and mentoring since the feed conservation technology was an innovative activity and high benefit. The activities result were two units of representative model cattle cage due to clean and hygienic aspects, one unit of feed storage, 400 kg corn straw silage, 300 kg rice straw ammoniation, and 100 kg concentrate.
Tujuan penelitian ini untuk mengetahui pengaruh umur panen terhadap produksi bahan kering dan komposisi kimia hijauan pada pertanaman campuran Sorghum plumosum, Botriochloa pertusa dan Pueraria phaseoloides. Penelitian ini menggunakan rumput Kume (Sorghum plumosum var. timorense), Suket putihan (Botriochloa pertusa) dan Tropikal kudzu (Pueraria phaseoloides). Metode penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 3 perlakuan dan 3 ulangan yaitu Pp40= S. plumosum + B. pertusa + P. phaseoloides dipotong pada umur 40 hari, Pp60= S. plumosum + B. pertusa + P. phaseoloides dipotong pada umur 60 hari dan Pp80= S. plumosum + B. pertusa + P. phaseoloides dipotong pada umur 80 hari. Variabel yang diukur ialah produksi bahan kering, kandungan bahan organik, protein kasar, serat kasar dan bahan ekstrak tanpa nitrogen. Hasil analisis statistik menunjukkan bahwa pertanaman campuran Sorghum plumosum, Botriochloa pertusa dan Pueraria phaseoloides berpengaruh sangat nyata (P<0,01) terhadap produksi BK, kandungan SK, PK dan BETN serta berpengaruh nyata (P<0,05) terhadap kandungan BO. Disimpulkan bahwa pertanaman campuran Sorghum plumosum, Botriochloa pertusa dan Pueraria phaseoloides pada umur panen 80 hari menghasilkan produksi bahan kering, kandungan BO dan SK tertinggi namun menghasilkan kandungan PK dan BETN yang rendah. Umur panen terbaik pertanaman campuran yaitu pada umur 60 hari karena kandungan SK hijauannya rendah dan kandungan proteinnya masih dalam taraf memenuhi kebutuhan ternak ruminansia. The purpose of this study was to determine the effect of harvest age on dry matter production and forage chemical composition in mixed crops of Sorghum plumosum, Botriochloa pertusa and Pueraria phaseoloides. This research used Kume grass (Sorghum plumosum var. timorense), Suket putihan (Botriochloa pertusa) and Tropical kudzu (Pueraria phaseoloides). The research method used a completely randomized design (CRD) with 3 treatments and 3 replications, namely Pp40 = S. plumosum + B. pertusa + P. phaseoloides were cut at 40 days of age, Pp60 = S. plumosum + B. pertusa + P. phaseoloides were cut at the age of 40 days. 60 days old and Pp80= S. plumosum + B. pertusa + P. phaseoloides were cut at 80 days old. The variables measured were dry matter production, organic matter content, crude protein, crude fiber and extracts without nitrogen. The results of the analysis showed that mixed cropping of Sorghum plumosum, Botriochloa pertusa and Pueraria phaseoloides had a very significant effect (P<0.01) on BK production, SK, PK and BETN content and significantly (P<0.05) on BO content. It was concluded that mixed cropping of Sorghum plumosum, Botriochloa pertusa and Pueraria phaseoloides at 80 days of harvest resulted in dry matter production, highest BO and SK content but low PK and BETN content. The best harvest age for mixed crops is at the age of 60 days because the content of SK forage is low and the protein content is still at the level of meeting the needs of ruminants.
This study aims to determine the effect of banana skin fermentation time using yeast Saccharomyces cerevisiae on concentration of VFA, N-NH3 and pH of rumen fluid in vitro. The method used in this study is an experimental method using a Completely Randomized Design (CRD) with 4 treatments and 3 replications. The treatments are P0 = banana skin flour without fermentation; P1 = Banana skin flour fermented for 7 days; P2 = Banana skin flour is fermented for 14 days; P3 = Banana skin flour fermented for 21 days. From the research conducted, the average value of VFA (mM) P0 = 87.98 ± 0.73; P1 = 130.96 ± 1.04; P2 = 131.74 ± 1.04; P3 = 133.03 ± 0.98; average NH3 (mM) P0 = 5.94 ± 0.67; P1 = 11.51 ± 0.56; P2 = 11.81 ± 1.33; P3 = 12.50 ± 1.20 while the average pH concentration P0 = 6.77 ± 0.06; P1 = 6.97 ± 0.06; P2 = 6.87 ± 0.15; P3 = 6.97 ± 0.06. Variance analysis (ANOVA) results showed that the treatment had a very significant effect (P <0.01) on VFA and N-NH3 concentration, and no significant effect (P> 0.05) on pH levels. The conclusion of this research is the fermentation of banana skin using yeast Saccharomycess cerevisiae with different length of time tends to increase the concentration of VFA and N-NH3. While the pH concentration increases during the fermentation period of 7 days and 21 days. Keywords: Banana skin, Long Fermentation, Saccharomycess cerevisiae, VFA, and N-NH3. Penelitian ini bertujuan untuk mengetahui pengaruh lama fermentasi tepung kulit pisang menggunakan khamir Saccharomyces cerevisiae terhadap konsentrasi VFA, N-NH3 dan pH cairan rumen secara in vitro.

Analisis data yang dikumpulkan menggunakan Analisis Of Variance (ANOVA). Hasil eksperimen menyatakan bahwa dari perlakuan yang digunakan berpengaruh tidak nyata (P>0,05) terhadap, VFA, N-NH3 dengan pH In-vitro. Dari hasil penelitian dapat disimpulkan, dedak sorgum mampu mensubsitusi jagung sampai pada level 75% dalam konsentrat.
Penelitian bertujuan untuk mengetahui pengaruh penggunaan kombinasi ekstrak serat buah lontar dan ekskreta ayam terhadap pemanfaatan serat pada ternak kambing yang mengkonsumsi rumput Bothriochloa pertusa. Ternak yang digunakan adalah kambing kacang jantan sebanyak 4 ekor yang berumur 6-8 bulan dengan berat badan awal rata-rata 12,2kg (KV=17%). Metode yang digunakan adalah percobaan dengan Rancangan Bujur Sangkar Latin (RSBL) dengan 4 perlakuan dan 4 ulangan yang terdiri dari BP = hay rumput Bothrichloa pertusa 40% + lamtoro 30% + konsentrat 30%, BPS = hay rumput Bothrichloa pertusa 40% + lamtoro 30% + konsentrat 20% + ekstrak buah lontar 10%, BPFA = hay rumput Bothrichloa pertusa 40% + lamtoro 30% + konsentrat 20% + ekskreta ayam 10%, dan BPSFA = hay rumput Bothrichloa pertusa 40% + lamtoro 30% + konsentrat 20% + ekstrak buah lontar 5% + ekskreta ayam 5%. Parameter yang diukur terdiri dari konsumsi dan kecernaan serat kasar, konsentrasi VFA(volatile fatty acid) rumen, dan glukosa darah. Hasil penelitian ini menunjukan bahwa penggunaan kombinasi ekstrak buah lontar dan ekskreta ayam tidak berpengaruh nyata (P>0,05) terhadap konsumsi dan kecernaan serat kasar, kadar glukosa darah, namun cenderung meningkat (P=0,08) konsentrasi VFA rumen. Disimpulkan bahwa penggunaan kombinasi ekstrak buah lontar dan ekskreta ayam tidak mempengaruhi konsumsi dan kecernaan serat kasar, kadar glukosa darah tetapi cenderung meningkatkan konsentrasi VFA pada ternak kambing yang mengkonsumsi rumput Bothriochloa pertusa. This study aims to determine the effect of using a combination of lontar fruit extract and chicken excreta on fiber utilization in goats that intake Bothriochloa pertusa grass. The livestock used were 4 male peanut goats aged 6-8 months with an average initial body weight of 12.2 kg (KV=17%). The experiment with design with Latin Square Design with 4 treatments and 4 treatments which consisted of BP = Bothrichloa pertusa grass hay 40% + lamtoro 30% + concentrate 30%, BPS = Bothrichloa pertusa grass hay 40% + lamtoro 30% + 20% concentrate + palm fruit extract 10%, BPFA = Bothrichloa pertusa grass hay 40% + lamtoro 30% + 20% concentrate + chicken excreta 10%, and BPSFA = Bothrichloa pertusa grass hay 40% + lamtoro 30% + 20% concentrate + lontar fruit extract 5% + chicken excreta 5%. The parameters observed were crude fiber intake and digestibility, intake of digestible crude fiber, VFA concentration rumen(volatile fatty acid) and blood glucose levels. Results showed that combined of lontar fruit extract and chicken excreta had no real effect (P>0.05) on crude fiber intake and digestibility, blood glucose consentration. But it tends to increase (P=0.05) at concentration of VFA rumen. It was concluded that the combination of lontar fruit extract and chicken excreta have no increase the of crude fiber intake and digestibility, blood glucose consentration but tends to increase at VFA concentration in goats that intake Bothriochloa pertusa grass.
