This study aims to determine the effect of some types of manure on growth and production of elephant grass (Pennisetum purpureum) cv. Taiwan. The expected results of this research can determine which is the type of manure suitable for the area of the former coal mines that have acid soils (marginal lands). This research using Complete Random Design with four treatments and six replications. The treatment is different source of manure which is control, cow manure, goat manure, and chicken manure. The parameters observed were plant growth including plant height, leaf width, leaf length, fresh weight production, and dry weight production. This study uses the acid soils of the former coal mine with a pH of 4.2 which is input into the polybags, seedlings of elephant grass (Pennisetum purpureum) cv Taiwan in the form of cuttings, Cow, goat and chicken dung are used as a source of manure. This research was conducted in the green house for 60 days. The results of the research obtained the data for plant height (cm) the highest Goat Manure (P2) 229.85; leaf Length (cm) the highest Goat Manure (P2) 113.10: Leaf width (cm) the highest Goat Manure (P2) 5.50; Production of Fresh Weight (gr/polybag) the highest Goat Manure (P2) 1361.67; the Production of Dry Weight (gr/polybag) the highest Goat Manure (P2) 214.28. The conclude that the manure suitable for the area of the former coal mines that have acid soils (critical area) is the manure from goat because it produces the highest growth and production than others.
The purpose of this study is to determine the quality of epididymis spermatozoa of buffalo after preservation with TALP media by adding serum with different level. The method used in this study is the experimental method and the design used is a randomized block design (RBD) with 3 treatment by adding bovine serum (0%, 5%, and 10%) and there are 6 replications as a group (repetition in the form of days). The result showed that the addition of serum into TALP diluent had a significant effect (P>0, 05) on the percentage of the motility of cauda epididymis spermatozoa of swamp buffalo after preservation which was 73, 33 in P2 10% serum and the viability is 79,167 ± 2,04 on P2 10%. This can be used as an indicator that the serum is effective in protecting spermatozoa from damages during the cryopreservation process, so by that, it would improve the quality of cauda epididymal spermatozoa of swamp buffalo. While the percentages of abnormality of cauda epididymis spermatozoa of swamp buffalo after preservation did not have a significant effect (P>0, 05). Based on the result of this study it can be concluded that the addition of 5% serum and 10% addition of egg yolk and 5% addition of glycerol will improve the quality of motility and viability and had no adverse effect on abnormalities after the preservation process at low temperature.
This research aimed to determine the fungi colonies total on the rumen content of cattle and buffaloes with the addition of leaves and oil palm fronds incubated for 7 days. Each of the contents of the rumen was added with molasses, soybean soaking water as an energy source for microorganisms, as well as the addition of oil palm fronds and palm leaves to expect the type of fungus that is expected to grow. Calculation of the total colonies fungi in the rumen contents was carried out using total plate count with the dilution method. Complete Random Design by Factorial used to analyze the statistic data. Factor A was the type of rumen content (A1 = rumen of cattle, A2 = buffalo rumen), factor B was the addition of palm fronds (B1 = only rumen contents, B2 = palm oil fronds, B3 = palm leaves, and B4 = palm oil fronds and palm leaves). The results showed that the total number of fungal colonies was significantly higher in the rumen contents of cattle with an average of 509.17 104 CFU / ml. The highest total number of fungal colonies was found in rumen contents with the addition of palm oil fronds, with an average colony number of 655.83 x104 CFU / ml, while the lowest was found in buffalo rumen contents with the addition of palm fronds and palm leaves (106.67x104 CFU / ml). The addition of oil palm fronds and palm leaves to the rumen contents did not have a different effect (p> 0.05).
Kelompok tani Sapakek Basamo merupakan kelompok tani yang bergerak dalam penggemukan sapi potong yang ada di Kelurahan Tanah Garam Kota Solok. Kelompok tani ini memiliki anggota sebanyak 25 orang dengan kepemilikan sapi masing- masing anggotanya berkisar 1-3 ekor sapi. Permasalahan yang dihadapi oleh kelompok mitra selama ini adalah pengelolaan kelompok dan usaha ternak yang masih sederhana, skala usaha yang masih kecil, dan belum mempunyai strategi dan program pengembangan usaha peternakan kelompok. Solusi yang akan diterapkan untuk mengatasi masalah mitra ini adalah melakukan penguatan kelompok baik manajemen organisasi, administrasi dan keuangan. Untuk meningkatkan pengetahuan anggota dan motivasi peningkatan pendapatan petani diperkenalkan cara menghitung analisa usaha peternakan, dimana untuk pengelolaan sebanyak 5 ekor sapi dapat memberi keuntungan sebesar Rp. 62.675.000. Kelompok mitra juga sudah dapat menyusun beberapa strategi pengembangan usaha peternakan berdasarkan identifikasi kondisi internal dan eksternal kelompok. Metode yang digunakan dalam penguatan sosial ekonomi kelompok tani ini adalah dengan penyuluhan dan FGD (Fokus Group Discussion).
Kelompok tani Garpondo merupakan kelompok tani yang bergerak dalam pembibitan dan penggemukan sapi potong unggul jenis Simmental. Permasalahan yang dihadapi oleh kelompok mitra selama ini adalah rendahnya tingkat kelahiran anak sapi denis kelamin jantan yang bisa dijadikan sebagai bakalan untuk penggemukan. Selanjutnya, hasil sampingan dari feses dan urin sapi tidak termanfaatkan untuk diolah menjadi sumber energi alternatif seperti gas bio. Solusi yang akan diterapkan untuk mengatasi masalah mitra ini adalah melakukan aplikasi inseminasi buatan dengan spermatozoa hasil sexing (jantan). Dengan ketersedian spermatozoa hasil sexing jantan dari tim pengabdian, maka aplikasi penerapan teknologi dengan inseminasi buatan akan menghasilkan kelahiran anak sapi jantan yang di inginkan oleh mitra karena nilai jual yang tinggi dan penggemukan dengan mudah. Selanjutnya melakukan pengolahan limbah peternakan seperti feses dan urin untuk pembuatan gas bio sebagai energi alternatif bagi kelompok mitra. Pembuatan gas bio ini menggunakan drum air kapasitas 1.100 liter/unit sebagai biodegester dan bisa menghasilkan gas bio yang siap dipakai oleh mitra. Ampas feses hasil fermentasi gas bio tersebut selanjutnya diolah lagi menjadi pupuk kompos yang bisa di jual kepada petani untuk tanaman pertanian dengan harga Rp. 25.000/karung. Metode yang dipakai dalam pencapaian tujuan tersebut adalah dengan penyuluhan dan praktek langsung ke lokasi mitra. Peternak juga akan dilatih dan diterapkan pembuatan fermentasi limbah pertanian sebagai alternatif pakan ternak.
