Abstrak Penanaman legum Indigofera dan rumput Gajah Kerdil merupakan teknologi pakan yang diterapkan dalam program UPSUS SIWAB di Sumatera Utara. Kajian bertujuan untuk mengevaluasi pemanfaatan legum Indigofera dan rumput Gajah Kerdil sebagai pakan sapi di Lokasi Demfarm yang terletak di Desa Gebang Kecamatan Pesiran Kabupaten Langkat . Metode kajian menggunakan sensus yang dilakukan pada 30 peternak sapi yang tergabung dalam kelompok ternak Sekata di lokasi tersebut. Data dianalisis secara deskriptif. Hasil kajian menunjukkan bahwa pemanfaatan legum Indigofera dan rumput Gajah Kerdil baru dapat memenuhi kebutuhan bahan kering, protein kasar dan TDN masing-masing 36,30 kg/h, 1,58 kg/h dan 20,07 kg/h. Persentase pemenuhan konsumsi bahan kering, protein kasar dan TDN masing-masing 5,82%, 27,92% dan 4,68%. Dapat disimpulkan bahwa pemenuhan nutrisi dari legum Indigofera dan rumput Gajah Kerdil masih rendah sehingga perlu dikembangkan lagi untuk mendukung peningkatan performans ternak.dan keberhasilan program. AbstractThe planting of Indigofera legumes and Dwarf Elephant grass is a feed technology applied in the UPSUS SIWAB program in North Sumatra. The study was aimed to evaluate the utilization of Indigofera legumes and Dwarf Elephant grass as cattle feed at the Demfarm Location, located in Gebang Village, Pesiran District, Langkat Regency. The method used a census conducted on 30 livestock farmers as members of Sekata group at that location. Data were analyzed descriptively. The results showed that the utilization of Indigofera legumes and Dwarf Elephant grass fullfil the needs of dry matter, crude protein and TDN were 36.30 kg/d, 1,58 kg/d and 20.07 kg/d respectively. The percentage fulfillment consumption of dry matter, crude protein and TDN were 5.82%, 27,92% and 4.68%, respectively. It can be concluded that the fulfillment of nutrition from Indigofera legumes and Dwarf Elephant grass is still low so it needs to be developed to support improvement of animal performance and program success.
