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.

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh penggunaan bafkenu (Kleinhovia hospita) dalam ransum komplit sebagai penganti rumput alam terhadap kandungan serat kasar serta kecernaan in vitro bahan kering dan bahan organik. Rancangan yang digunakan adalah rancangan acak lengkap ) dengan 4 perlakuan dan 4 ulangan yaitu R0= Ransum komplit terdiri dari 70% hijauan rumput alam + 30% konsentrat; R1= Ransum komplit terdiri dari 70%hijauan (85% rumput alam + 15% daun bafkenu) + 30% konsentrat; R2= Ransum komplit yang terdiri dari 70%hijauan (70% rumput alam +30% daun bafkenu) + 30% konsentrat; dan R3= Ransum komplit yang terdiri dari 70%hijauan (55% rumput alam + 45% daun bafkenu) + 30% konsentrat. Analisis data menggunakan analysis of variance (ANOVA) dan uji BNT. Hasil penelitian menunjukkan bahwa perlakuan berpengaruh nyata (P<0.05) terhadap kandungan serat kasar , tetapi tidak nyata (P>0,05) terhadap kecernaan in vitro bahan kering serta bahan organik. Pada tingkat substitusi rumput alam dengan daun bafkenu 45% dari proporsi hijauan 70% dalam ransum komplit adalah paling baik dilihat dari bahan kandungan serat kasar meskipun memberikan nilai kecernaan bahan organik dan kecernaan bahan kering yang relatif sama dengan perlakuan lainnya The purpose of this study was to determine the effect of using bafkenu (Kleinhoviahospita) leaves in complete rations as a substitute for natural grass on crude fiber content and in vitro digestibility of dry matter and organic matter. The design used was a completely randomized design with 4 treatments and 4 replications, namely R0 = complete ration consisting of 70% natural grass forage + 30% concentrate; R1 = Complete ration consisting of 70% forage (85% natural grass + 15% bafkenu leaves) + 30% concentrate; R2 = Complete ration consisting of 70% forage (70% natural grass + 30% bafkenu leaves) + 30% concentrate; and R3 = complete ration consisting of 70% forage (55% natural grass + 45% bafkenu leaves) + 30% concentrate.. The data were analyzed using analysis of variance and if it had a significant effect, it was continued with the BNT test. The results of statistical analysis showed that the treatment had a significant effect (P<0.05) on crude fiber content, was not significant (P>0.05) while the in vitro digestibility of dry matter and organic matter At the level of substitution of natural grass by bafkenu leaves, 45% of the proportion of 70% forage in complete rations was the best in terms of crude fiber content even though it provide the same digestibility of organic matter and dry matter digestibility as other
ABSTRAK Penelitian ini bertujuan untuk mengetahui pola pertumbuhan dan perkembangan morfologi Rumput Kume (Sorghum plumosum var. Timorense) dan Bothriochloa pertusa yang ditanam secara monokultur maupun campuran. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan empat perlakuan dan tiga ulangan. Keempat perlakuan tersebut SPM = Sorghum plumosum monokultur, SPC= Sorghum plumosum campuran, BPM= Bothriochloa pertusa monokultur, BPC=Bothriochloa pertusa campuran. Parameter yang diukur terdiri dari jumlah rumpun, tinggi tanaman, jumlah daun, panjang daun dan lebar daun. Hasil analisis statistik menunjukkan bahwa pertumbuhan dan perkembangan morfologi rumput Kume (Sorghum plumosum var. Timorense) dan Bothriochloa Pertusa yang ditanam secara monokultur maupun campuran menunjukkan perbedaan yang sangat nyata (P<0,01) terhadap jumlah rumpun, tinggi tanaman, jumlah daun, panjang daun dan lebar daun. Disimpulkan bahwa introduksi rumput S. plumosum menunjukkan pengaruh kearah yang tidak baik pada pertumbuhan dan perkembangan morfologi dari rumput B. pertusa. Hal ini dapat dibuktikan tidak terjadi perubahan pada pertumbuhan rumput B. pertusa ketika ditanam campur dengan rumput S. plumosum jika dibandingkan rumput B. pertusa ditanam secara monokultur pada beberapa tingkatan umur. This study aims to determine the growth pattern and morphological development of kume grass (Sorghum plumosum var. Timorense) and Bothriochloa pertusa grown in monoculture or mixed. The experiment used a Complete RandomIzed Design (RAL) with four treatments and three repeats. The four treatments were SPM = Sorghum plumosum monoculture, SPC = Sorghum plumosum mixed, BPM = Bothriochloa pertusa monoculture, BPC = Bothriochloa pertusa mixed. The parameters measured are number of clumps, height, the number of leaves, the length and the width of the leaves. The result of statistical analysis showed that the growth and morphological development of Kume grass (Sorghum plumosum var. Timorense) and Bothriochloa Pertusa grown monoculturally or mixed show very significant differences (P<0.01) to the number of clumps, plant height, number of leaves, leaf length and leaf width. It was concluded that the introduction of S. plumosum grass showed an adverse influence on the growth and morphological development of the B. pertusa. It can be proven that there is no change in the growth of B. pertusa grass when it is mixed with S. plumosum grass when compared to B. pertusa grass grown in monoculture at several age levels. Keywords: Sorghum plumosum, Bothriochloa pertusa, morphology.
