Leucaena KX2 termasuk tanaman pakan ternak leguminosa pohon serbaguna dan toleran terhadap serangan hama kutu loncat. Pengembangan tanaman ini untuk budidaya ataupun untuk tujuan konservasi masih belum optimal karena terbatasnya bibit. Teknik kultur jaringan merupakan alternatif teknologi yang mampu menyediakan bibit secara massal, seragam dan relatif cepat. Tahap yang harus dilakukan dalam perbanyakan bibit melalui kultur jaringan adalah multiplikasi tunas yang menjadi kunci keberhasilan teknik perbanyakan ini. Penelitian dilakukan di laboratorium kultur jaringan BB-Biogen dan Ciawi untuk induksi tunas dan multiplikasi tunas. Penelitian dilakukan dalam dua tahap (1) induksi tunas (2) multiplikasi tunas secara invitro. Hasil penelitian menunjukkan bahwa media MS dan WPM + BA 0,5 mg/lt untuk induksi tunas lebih baik dibanding pada media MS (kontrol). Kemudian multiplikasi tunas diperoleh pada media MS + BA 0,5 mg/lt + TDZ 0,03 mg/lt dengan jumlah tunas rata-rata 4,0 tunas dan jumlah daun 7 helai lebih tinggi dibanding pada media MS + BA 0,05 +TDZ 0,01 mg/lt maupun penambahan TDZ 0,05 mg/lt rata-rata 4,2 tunas dengan 6 daun. Penggunaan media MS untuk induksi dan multiplikasi tunas diperoleh tunas lebih rendah dibanding pada media WPM

The food flavor manufacture waste (called Sipramin) have a great potential to used as liquid organic fertilizer due to the nutrition contents that needed by plants. The objectives of this research were to evaluate the effect of sipramin as liquid organic fertilizer on soil condition, re-growth, and herbage productivity of Indigofera sp. For ruminants. This experiment used factorial completely randomized design; the first factor was fertilizer dosages (0, 10, 20 and 40%) and the second factor was fertilization times (30 and 15 days before harvested [dbh]). The observed variables were soil chemical and biological characteristic, re-growth and forage production, and nutritive value of Indigofera sp. for ruminants. The data were analyzed by analysis of variance. The result showed that the soil nitrogen, number of phosphate resolvability bacteria and Rhizobium sp. were significantly different (P<0.05) on 40% fertilizer dosage than the other treatments. The phosphate resolvability bacteria and available phosphate (P available) of 15 dbh were higher than 30 dbh. Sipramin fertilizer of 40% dosage improved C-organic content and carbon to nitrogen (C/N) ratio value of soil, and significantly (P<0.01) increased forage production (leaf and steam). The leaf and steam ratio of 15 dbh were higher than 30 dbh. There were significantly different (P<0.01) on number of root nodule on 40% dosage than others. The addition of 40% sipramin at 15 dbh fertilization time showed the best result to chemical and biological soil characteristic, re-growth, and productivity of Indigofera sp.

Production, quality and availability of forage one of which is determined by soil fertility and soil health. The use of chemical fertilizers (inorganic) in a period of time is one of the causes of land degradation (Kartini, 2007), application of organic fertilizers is the right step in maintaining soil fertility and soil health, and reduce the negative impact of the use of inorganic fertilizers. The study aimed to evaluate the response of regrowth and production of several species of grass to organic fertilizer conducted in a greenhouse using a completely randomized design split plot pattern 3 x 4 with three replications. The first factor (main plot / main plot) is a type of grass is Panicum maximum var. trichoglume (R1), Setaria splendida (R2), and Pennisetum purpureum (R3); The second factor (sub-plot / subplot) is a type of organic fertilizer that is without fertilizer (P0), manure (P1), compost (P2), and vermicompost (P3). The results showed that there was no interaction effect between type of grass with the type of organic fertilizer on the regrowth and production of grass Panicum maximum var. trichoglume, Setaria splendida, and Pennisetum purpureum. Treatment types of grass significant (P <0.05) on all observed variables, while the treatment of organic fertilizers only significant (P <0.05) in the variable number of tillers, number of leaves, stem dry weight, total dry weight of forage and leaf area per pot. Based on the results of this study concluded that there was no interaction effect between type of grass with organic fertilizer. The three types of grass have different productivity, highest growth in grass with vermicompost fertilizer and highest production in grass with compost fertilizer.Key words: Organic fertilizers, panicum grass, Setaria grass, elephant grass

Peranan ternak sapi sebagai sumber pangan berupa daging bagi masyarakat. Permasalahannya populasi ternak sapi di Sulawesi Utara cenderung mengalami penurunan. Lambatnya pertumbuhan populasi ternak sapi ditentukan oleh faktor eksternal diantaranya pakan. Berdasarkan pemikiran tersebut maka telah dilakukan pengkajian tentang introduksi hijauan makanan ternak sapi di Minahasa Selatan. Dasar pemikiran bahwa ternak sapi merupakan komoditas andalan sehingga pemerintah perlu mengupayakan kebijakan berkaitan dengan ketersediaan hijauan pakan ternak secara kontinyu. Hijauan Makanan Ternak (forages) merupakan bahan makanan atau pakan utama bagi kehidupan ternak serta merupakan dasar dalam usaha pengembangan peternakan. Untuk meningkatkan produktivitas ternak, salah satu faktor penting yang harus diperhatikan adalah penyediaan pakan sepanjang tahun baik kualitas dan kuantitas yang cukup. Dalam merespon kebijakan pemerintah maka di Minahasa Selatan telah dilakukan pengembangan hijauan makanan ternak sapi. Kesimpulannya, introduksi hijauan makanan ternak sangat bermanfaat bagi petani peternak dalam pengembangan ternak sapi. Berdasarkan introduksi hijauan maka perlu pendampingan bagi petani peternak untuk manajemen hijauan.
