ABSTRAKPenelitian ini bertujuan untuk mengetahui karakteristik morfologis dan reproduksi kerbau pampangan di Propinsi Sumatera Selatan. Dilaksanakan di tiga kabupaten yaitu kabupaten OKI, Banyuasin dan Ogan Ilir selama 6 bulan. Metode yang digunakan adalah metode survei. Penarikan contoh bersifat multistage purposive sampling mulai dari penentuan kabupaten, kecamatan, serta peternak. Setelah ditetapkan tiga kabupaten lokasi sampel, akan dipilih masing-masing satu kecamatan sentra populasi yang jumlah populasinya terbanyak. Data yang dikumpulkan meliputi data primer dan data sekunder. Data yang diperoleh diolah secara matematis, disajikan secara tabulasi kemudian dijelaskan secara deskriptif, yaitu melukiskan secara sistematis fakta atau karakteristik morfologis dan reproduksi kerbau pampangan secara cermat dan faktual dari data yang telah terkumpulkan. Karakteristik morfologis kerbau pampangan adalah warna bulu hitam/hitam keabu-abuan, bentuk tubuh besar, temperamen tenang, kepala besar dan telinga panjang, tanduk ada yang tegak panjang dan melingkar ke arah belakang dan ada juga yang arah ke bawah. Bentuk ambing simetris dan berkembang dengan baik.

Abstract. Muhakka, Suwignyo RA, Budianta D, Yakup. 2019. Vegetation analysis of non-tidal swampland in South Sumatra, Indonesia and its carrying capacity for Pampangan buffalo pasture. Biodiversitas 20: 1077-1086. In Indonesia, non-tidal swampland area is 13.27 million ha, only 4 million ha has been developed with details of 2.6 million ha that managed by the public and the private sector and 1.3 million ha with government assistance. This study aims to analyze vegetation structure of non-tidal swampland in Pulau Layang Village, Ogan Komering Ilir District, South Sumatra, Indonesia and Rambutan Village, Banyuasin District, South Sumatra, Indonesia and to examine its carrying capacity for Pampangan buffalo pasture. Methods used were by the combination of direct observation, survey using plot sampling with total 50 observation plots, and measurements to determine forage production using Halls method. The results show that there 19 forage species were in two studied areas which are potential as Pampangan buffalo feed. Species with the highest Important Value Index were Purun tikus (Eleocharis .dulcis) with 89.71% and Kumpai padi (Oryza. rufipogon) with 54.08%. The production of fresh forage and dry matter in the wet season in Pulau Layang was 6.90 tons ha-1 year-1 and 1.27 tons ha-1 year-1, respectively, whereas in Rambutan they were 3.68 tons ha-1 year-1 and 0.91 tons ha-1 year-1, respectively. The production of fresh forage and dry matter in the dry season in Pulau Layang was 4.86 tons ha-1 year-1 and 0.99 tons ha-1 year-1, respectively, while in Rambutan they were 2.52 tons ha-1 year-1 and 0,71 tons ha-1 year-1, respectively. The pasture carrying capacity in Pulau Layang in the wet season was 3.66 AU (Animal Unit) ha-1 year-1 and in the dry season, it was 2.85 AU ha-1 year-1, while in Rambutan Village it was 2.61 AU ha-1 year-1 and 2.04 AU ha-1 year-1, respectively. There were six species of forage with high production, namely Kumpai tembaga (Hymenachne acutigluma) Kumpai padi (Oryza rupifogon), Kumpai minyak (Hymenachne amplexicaulis), Are bolong (Polygonum barbatum L), Bento rayap (Leersia hexandra) and Purun tikus (Eleocharis dulcis). It is estimated that there still can be added buffalo cattle as much as 0.31 AU ha-1 year-1 in Pulau Layang Village so 155 buffaloes and 0.59 AU ha-1 year-1 in Rambutan Village.709 buffaloes
An experiment was conducted to study the effects of lamtoro (Leucaena leucocephala) leaf supplementation in fermented kumpai grass (Hymenachne amplexia calis) based rations on the productivity of Bali cattle. Variables measured were dry matter and organic matter intakes, nutrient digestibility (dry matter, organic matter, crude protein, and crude fiber), body weight gain, and feed efficiency. The types of rations were: Ration A= 45% fermented kumpai grass + 40% benggala grass + 15% concentrate + 0% lamtoro leaf, Ration B= 45% fermented kumpai grass + 30% benggala grass + 15% concentrate + 10% lamtoro leaf, Ration C= 45% fermented kumpai grass + 20% benggala grass + 15% concentrate + 20% lamtoro leaf, and Ration D= 45% fermented kumpai grass + 10% benggala grass + 15% concentrate + 30% lamtoro leaf. The supplementation of lamtoro leaf up to 30% into the ration could increase (P<0.05) dry matter and organic matter intakes, and crude protein digestibility. The highest body weight gain and feed efficiency were found in Bali cattle fed ration with 20% lamtoro leaf supplementation. The level of lamtoro leaf supplementation in the ration did not affect the digestibility of dry matter, organic matter, and crude fiber. It was concluded that the supplementation of lamtoro leaf in the ration could increase dry matter, organic matter, and crude protein intakes. Addition of 20% lamtoro leaf gave the best effect on the increased body weight gain and feed efficiency in Bali cattle.
Abstract. This study was aimed to determine nutritional value of lowland tidal grass fermented by probiotic microorganisms. This study used a completely randomized design and investigated two factors, namely varieties of lowland tidal grass (kumpai tembaga (Ischaemum rugosum), kumpai minyak (Hymenachne amplexicaulis) and kumpai padi (Oryza rufipogon)) and probiotic microorganism concentration (0.3, 0.5, 0.7 and 0.9 percent). The following parameters were observed, including dried matter content, crude protein content and crude fiber content. The results showed that the use of probiotics have significant effects on crude protein content and crude fiber content. In conclusion, the use of probiotics can improve the nutritional value of grass. The best result was obtained on kumpai tembaga grass (Ischaemum rugosum) fermented with 0.7% probiotic microorganism.Keywords: nutritional evaluation, lowland tidal grass, fermentation, probiotics microorgansms Abstrak. Penelitian ini bertujuan untuk menentukan nilai nutrisi rumput tidal dataran rendah yang difermentasi menggunakan mikroba probiotik. Penelitian menggunakan rancangan acak lengkap dan mengamati dua faktor, yaitu varitas rumput tidal dataran rendah (kumpai tembaga (Ischaemum rugosum), kumpai minyak (Hymenachne amplexicaulis) dan kumpai padi (Oryza rufipogon)) dan mikroba probiotik (0,3; 0,5; 0,7 dan 0,9 persen). Parameter yang diamati meliputi kandungan bahan kering, protein kasar, dan serat kasar. Hasilnya menunjukkan bahwa penggunaan probiotik memiliki pengaruh nyata terhadap kandungan protein kasar dan serat kasar. Dapat disumpulkan bahwa penggunaan probiotik dapat meningkatkan nilai nutrisi dari rumput. Hasil terbaik diperoleh pada rumput kumpai tembaga (Ischaemum rugosum) yang difermentasi menggunakan 0,7% mikroba probiotik.Kata kunci: evaluasi nutrisi, rumput tidal dataran rendah, fermentasi, mikroba probiotik
