Penelitian dilaksanakan di kelompok sapi perah Harapan Jaya, desa Haurngombong, Tanjung Sari, Sumedang. Tujuan penelitian ialah untuk mengetahui dampak subtitusi konsentrat oleh daun kering Kaliandra dalam ransum sapi perah terhadap kuantitas dan kualitas produksi susu, perubahan bobot badan dan pendapatan peternak sapi perah di kelompok peternak sapi perah harapan Jaya anggota KSU Tandangsari, Tanjungsari, Sumedang. Penelitian menggunakan rancangan acak kelompok (RAK) empat perlakuan dan empat kelompok yang dikenakan pada 16 ekor sapi perah dengan ransum perlakuan terdiri atas R1 (rumput + 100% konsentrat), R2 (rumput + 90% konsentrat + 10% daun kering Kaliandra), R3 (rumput + 80% konsentrat + 20% daun kering Kaliandra), dan R4 (rumput + 70% konsentrat + 30% daun kering Kaliandra). Peubah yang diamati adalah kuantitas dan kualitas susu dengan analisis statistik kontras ortogonal dan pendapatan bersih usahaternak dianalisis berdasarkan anggaran parsial. Hasil penelitian memberi kesimpulan bahwa substitusi konsentrat oleh daun daun kering Kaliandra sampai 20% dalam ransum mempengaruhi kuantitas produksi susu 4% FCM tetapi tidak terhadap produksi harian, kualitas susu, dan perubahan bobot badan sapi perah serta memberi tambahan pendapatan bagi peternak sapi perah. Berdasarkan hasil penelitian maka disarankan bahwa untuk penerapan di lapangan agar produksi susu meningkat dan memberi manfaat ekonomi sebaiknya digunakan daun Kaliandra seanyak 20% sebagai pengganti konsentrat.

The research was conducted at Harapan Jaya dairy cattle group, Haurngombong village, Tanjungsari, Sumedang. The objective of the research was id study the role of kaliandra (CALLIANDRA CALOTHYSUS) dry leaf substituting the dairy cattle concentrate on; quality and quantity of milk yield, animal weight, and farmer’s income. The treatments were divided into four : R1 (rice straw + l00% concentrate), R2 (nec straw + 90% concentrate + 10% Kaliandra leaf) R3 (rice straw + 80% concentrate + 20% Kaliandra leaf), and R4 (rice Straw + 70% concentrate + 30% Kaliandra leaf). The 16 heads of dairy cattle were divided into four blocks and replicated four times each. The experiment was done based on a randomized block design for milk quantity and quality and the mean of treatment was statistically analyzed using orthogonal contrast. The farmer’s net income was analyzed based on the partial budget analysis The result showed that concentrate Substitution by Calliandra dry leaf up to 20% level affected the 4% FCM milk yield but it did not affect the milk quality and average daily gain and also raise of the farmer’s income, lt is suggested that 20% subtitution of the concentrate by Calliandra leaf is the best level to increase the milk production and to give economic use.
