ABSTRAK Pupuk cair yang memanfaatkan bahan organik seperti urin yang difermentasi dan zat pengatur tumbuh dapat memberikan tambahan unsur hara yang diperlukan rumput untuk tumbuh. Upaya perbaikan kualitas rumput gajah dapat dilakukan dengan pemberian pupuk daun “organik”, dengan memperhatikan dosis pemberiannya. Tujuan penelitian ini adalah menentukan dosis pemberian pupuk daun “organik” yang tepat untuk mendapatkan kualitas hijauan yang maksimal. Materi penelitian ini meliputi pupuk daun “organik” dan bibit rumput gajah dalam keadaan pols, dengan rata-rata panjang perpols adalah 10 cm. Penelitian menggunakan metode percobaan dengan menggunakan rancangan acak lengkap (RAL) dengan 4 perlakuan dan masing-masing perlakuan menggunakan 5 kali ulangan. Perlakuan yang diberikan adalah P0 (kontrol), P1 (5% pupuk daun “organik”), P2 (10% pupuk daun “organik”) dan P3 (15% pupuk daun “organik”). Hasil penelitian ini menunjukkan bahwa perlakuan pemberian dosis pupuk daun “organik” yang berbeda memperikan pengaruh yang sangat nyata (P<0,01) terhadap kandungan Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), selulosa, hemiselulosa, lignin, kecernaan in vitro bahan kering dan kecernaan in vitro bahan organik rumput gajah. Berdasarkan penelitian ini pemberian dosis 15% pupuk daun “organik” menunjukkan hasil yang paling baik.Kata kunci: komposisi kimiawi. pupuk daun organik, rumput gajah, , kecernaanABSTRACTLiquid fertilizers using organic ingredients such as bio urine can provide additional nutrients to optimize the grow of grass. Efforts to improve the quality of elephant grass can be done by providing this organic fertilizer by calculating the dosage given. The purpose of this study was to determine the appropriate dosage of “organic” leaf fertilizers to obtain maximum forage quality. The research material used were “organic” leaf fertilizers and elephant grass seedlings in a state of pols, with an average length of each pols is 10 cm. The research method is experiment using a completely randomized design (CRD) which consisted of 4 treatments and 5 repetitions. The treatments given in this study were P0 (control), P1 (5% “organic” leaf fertilizers), P2 (10% “organic” leaf fertilizers) and P3 (15% “organic” leaf fertilizers). The results of this study indicate that the implementation of different dosages of “organic” leaf fertilizers had significant effect (P <0.01) on the content of Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), cellulose, hemicellulose, lignin, dry matter digestibility (in vitro) and organic matter digestibility (in vitro) of elephant grass. Based on this study, 15% dose of “organic” leaf fertilizers showed the best results.Keywords: chemical compounds, digestibility, elephant grass, organic leaf fertilizers

The problem that often comes by farmers is a shortage of feed in the dry season; one of the technologies that can be used is silage. Carrot straw (CRS) can be used as a silage material because of its abundance and nutritional value, which is good for the livestock. The purpose of this study is to know about the differences in the provision of feed additives, i.e., Lactobacillus casei-A, Lactobacillus plantarum, and Lactobacillus casei-B of the composition of CRS  silage. Making silage by means of CRS was weighed, CRS was placed on a tray and added with feed additives based on experimental treatment, CRS was mixed thoroughly, stored, and closed in a laboratory-scale silo then placed at 26-28oC. CRS was given with three different feed additive treatments: CRS + 0.01% Lactobacillus casei-A, CRS + 0.01% Lactobacillus plantarum, CRS + 0.01% Lactobacillus casei-B. Ensiling was carried out for 21 days in four replications for each treatment, and each replication was made in duplicate. Statistical analysis after the data was obtained was using the SAS University application specification 4.0 red hat (64-bit) with code, and the difference between the treatment means (P<0.01) was determined using Duncan’s Multiple Range Test (DMRT). This study resulted that the different types of use of lactic acid bacteria had a significant effect (P<0.01) on organic matter content (OM), crude fiber content (CF), extract ether content (EE), nitrogen-free extract (NFE), neutral detergent fiber (NDF) and acid detergent fiber (ADF). This study concludes that the difference in the provision of feed additives affects the chemical composition of carrot straw silage. To sum up, Lactobacillus casei-A has a good value on NFE while Lactobacillus casei-B has a good value on OM, CF, EE, NDF, and ADF.

Permasalahan rutin yang kerap dialami peternak di Desa Tlekung, Kec. Junrejo, Kota Batu adalah sulitnya memenuhi kebutuhan pakan hijauan disaat musim kemarau. Di satu sisi, Desa Tlekung berdampingan dengan lereng Gunung Panderman, yang didalamnya terdapat hutan dengan potensi hijauan sebesar 141.636 ton per tahunnya. Lahan hutan sanggup memasok kebutuhan pakan hijauan disaat musim penghujan, namun hijauan menjadi kering dan langka pada musim kemarau. Akibatnya, peternak mengupayakan pemenuhan kebutuhan pakan pada musim kemarau melalui penggunaan jerami padi. Walaupun demikian, cadangan jerami hasi penanaman di lahan sawah di Desa Tlekung tidak mencukupi untuk memenuhi kebutuhan pakan. Usaha dalam mengatasi kekurangan pakan di musim kemarau dilakukan dengan membeli jerami padi dari luar kecamatan. Upaya ini bukanlah solusi yang tepat guna dalam mengatasi kekurangan hijauan, karena nilai nutrisi yang terkandung dalam jerami padi tidak dapat mencukupi kebutuhan hidup sapi dan domba. Tujuan yang ingin dicapai dalam program pengabdian ini adalah untuk mengenalkan, meningkatkan kesadaran dan memotivasi peternak agar mampu serta berkeinginan untuk menerapkan teknologi ensilase, guna menghasilkan silase sebagai cadangan pakan hijauan disaat musim kemarau. Berdasarkan hasil tahapan evaluasi yang telah dilakukan, tingkat keberhasilan dapat melebihi target kriteria keberhasilan yang telah dilakukan. Secara umum, peserta menyatakan penyelenggaraan pelatihan adalah hal yang penting dan dibutuhkan, dimana peserta menyatakan memahami materi yang diberikan, mampu mempraktekkan pembuatan silase, serta sebagian peserta akan mengimplementasi pembuatan silase. Dengan demikian, kegiatan pendampingan ini dapat dikatakan berhasil, karena mampu meningkatkan pengetahuan dan kemampuan peserta dalam mengikuti kegiatan pengabdian.
