Abstract

Peternak sapi potong hanya mendapatkan penghasilan tahunan ketika penjualan sapi, amun tidak memiliki pendapatan pekanan atau bulanan dari beternak tersebut. Salah satu cara untuk menigkatkan pendapatan peternak di Sipujuk Farm adalah dengan mengelola kotoran sapi yang tidak bernilai dan malah menjadi sumber polusi dan merusak lingkungan menjadi pupuk organik yang bernilai ekonomis yang dapat memberikan pendapatan rutin bagi peternak dan lingkungan juga dapat terpelihara. Peternakan sapi potong di Si Pujuk Farm menghasilkan limbah yang meliputi kotoran berupa limbah padat, cair, gas, ataupun sisa pakan. Kotoran ternak yang dihasilkan di Si Pujuk Farm belum dimanfaatkan secara optimal, diantaranya terbuang begitu saja, sehingga sering mencemari lingkungan dengan bau yang tidak sedap sehingga mengganggu kenyamanan lingkungan. Tujuan dari pengabdian ini adalah meningkatkan ekonomi dari peternak dengan cara meningkatkan nilai ekonomis kotoran sapi menjadi pupuk organik memanfaatkan mikroorganisme lokal (MOL) kuli buah. Metode yang digunakan adalah observasi, sosialisasi, pelatihan, pembinaan dan evaluasi. Berdasarkan pengabdian yang telah dilaksanakan, Sipujuk Farm sudah mendapat merealisasikan pembuatan MOL yang ekonomis dan berkualitas dari limbah kulit buah terutama kulit nenas dan memproduksi pupuk organik yang berkualitas dan dapat dijual secara komersil

Abstract

Tanaman sorgum dapat diratun atau tumbuh dan berbuah kembali setelah dipanen. Penelitian bertujuan untuk mengobservasi produksi tanaman ratun sorgum manis varietas Numbu dan CTY-33 sebagai penghasil hijauan, biji dan brix gula tinggi serta interaksinya di tanah ultisol. Penelitian dilaksanakan secara eksperimen di Kebun Percobaaan Fakultas Peternakan Universitas Andalas Padang, menggunakan  rancangan acak kelompok fola faktorial 4 ulangan. Faktor pertama adalah varietas sorgum manis varietas CTY-33 dan Numbu, faktor kedua tanaman primer dan tanaman ratun I.  Tanaman primer adalah tanaman yang berasal dari biji yang dipanen umur 100 hari.  Tanaman ratun I adalah tanaman yang tumbuh dari pangkal batang primer yang telah dipanen (84 hari setelah ratun/HSR). Pemanenan dilakukan pada fase masak fisiologi. Hasil penelitian terdapat interaksi sangat nyata (P<0.01) varietas dan peratunan terhadap tinggi tanaman, diameter batang dan lebar daun. Varietas Numbu mengasilkan tinggi tanaman tertinggi pada tanaman primer 218.12 cm sedangkan diameter batang dan lebar daun CTY-33 pada tanaman primer mengungguli Numbu dengan nilai berturut-turut 17.27 mm dan 9.07 cm. Produksi segar dan bahan kering (BK) lebih dipengaruhi oleh faktor Varietas.  Varietas Numbu menghasilkan produksi berbeda sangat nyata (P<0.01) lebih tinggi  berturut-turut 58.57 ton/ha dan 18.40 ton/ha. Terdapat interaksi sangat nyata (P<0.01) antara varietas dan peratunan terhadap Brix gula. Penurunan kadar Brix gula pada CTY-33 dan Numbu mencapai 87,36%  dan 71,24%. Dari hasil penelitian dapat disimpulkan dalam budidaya ratun varietas Numbu menghasilkan pertumbuhan yang lebih tinggi cocok untuk tujuan produksi biomasa segar dan BK, sedangkan CTY-33 lebih cocok untuk tujuan penghasil biji. Budidaya  ratun menyebabkan kandungan Brix kedua varietas menurun.

Abstract

The Etawa Dairy Goat Farming Program is one of the Economic Sector programs of UPZ BAZNAS PT Semen Padang by distributing a grant of 42 Etawa crossbred goats (ECG) to seven underprivileged Heads of Families (KK). UPZ BAZNAS PT Semen Padang chose dairy goats because they have high economic potential. Challenges in raising dairy goats include feed management, livestock health, and poor maintenance techniques. The dairy goat maintenance system in the community is traditional. Poor feed quality impacts production, reproduction, and livestock health. To make the dairy goat grant effective, assistance is needed to guide farmers on feed, health, and maintenance so that goat farming can benefit farmers and become a family business unit. The Faculty of Animal Science Service Team and students of the Animal Science Study Program at Universitas Andalas carry out community service activities from July to November 2024. The community service activities method includes surveys, counseling, and activity evaluation. After the community service activities, improvements were seen in feed management, and farmers became skilled at handling scabies in livestock. Based on the community service activities that have been carried out, it can be concluded that farmers' knowledge about dairy goat maintenance management has increased. Farmers are skilled at treating scabies with traditional medicine because it is effective and more economical.

Abstract

Brown Midrib (BMR) sorghum is a mutation-derived variety with low lignin and high non-structural carbohydrate content, potential as a ruminant forage. The ratoon system allows for repeated harvesting without replanting, thus providing an efficient forage supply. This study aimed to evaluate the agronomic characteristics and biomass productivity of BMR mutant sorghum in primary plants, the first and second ratoon. The study was conducted experimentally using a randomized block design with three treatments (primary, first ratoon, and second ratoon plants) and four replications. The parameters observed included agronomic components (plant height, number of tillers, stem diameter, and leaf size), stem sugar value (Brix), proportion of plant structures (stems, leaves, and panicles), panicle production, forage production, and livestock carrying capacity. The results showed that plant height was not significantly different (P>0.05) between primary and ratoon plants, while stem diameter and leaf size decreased gradually from the first to the second ratoon. The Brix value showed a highly significant difference (P<0.01), with the highest value in the first ratoon and the lowest in the second ratoon. The proportion of stems and leaves decreased in the second ratoon, whereas the proportion of panicles and panicle production increased significantly (P<0.01). The highest forage production was obtained in the second ratoon at 52.08 tons/ha, while the total production of the three harvests reached 112.28 tons/ha with a carrying capacity of 8.8 AU/ha. From the results of this study, it can be concluded that the ratoon system does not reduce the biomass productivity of BMR mutant sorghum and can maintain agronomic quality until the second ratoon. With its high production potential and good regrowth ability, BMR mutant sorghum is worthy of development as a sustainable forage source in ruminant livestock farming systems.

Abstract

HIGHLIGHTS- Bacillus sp. probiotics can replace 100% inorganic phosphate fertilizer.- Sorghum stem diameter strongly correlates with juice volume.- Juice yield was not affected by phosphorus dose or Bacillus sp. colony size.- Sorghum juice sugar content reached 11.77–12.75% Brix.- Phosphate-solubilizing bacteria improved phosphorus availability in ultisol. ABSTRACTThis study was conducted to observe the effects of phosphate-solubilizing bacteria (PSB) combined with different phosphorus fertilizer levels on the juice characteristics of the BMR sorghum mutant line. The research was carried out at the Edufarm of the Faculty of Animal Science, Andalas University, Padang, using a randomized block design (RBD) with four treatments and four replications. The treatments were as follows: P0 = Urea + KCl + 0% TSP + PSB; P1 = Urea + KCl + 50% TSP + PSB; P2 = Urea + KCl + 75% TSP + PSB; and P3 = Urea + KCl + 100% TSP (control). The PSB used was obtained from Waretha Probiotics, consisting of Bacillus sp. culture at a dose of 10 mL per planting hole, equivalent to 10⁷ cfu/g. The parameters measured were sugar content (%Brix), volume of stem juice (mL), and the correlation of various parameters with stem juice volume. The results showed that the application of probiotic Bacillus sp. and different dosages of phosphorus fertilizer did not result in significant differences for all parameters (P > 0.05). Sugar content and juice volume ranged from 11.78 to 12.75 (%Brix) and 188.75 to 218.5 (mL/stem), respectively. The correlation coefficient analysis indicated significant positive correlations between stem diameter (r = 0.575*) and fresh stem weight (r = 0.504*) with the volume of sorghum stem juice. It was concluded that the application of PSB from Bacillus sp. can replace phosphorus fertilizer, producing sugar content and juice yield comparable to the 100% P fertilizer treatment. A correlation was observed between stem diameter and fresh stem weight with stem juice volume. PSB was found to play a crucial role in increasing phosphate availability to plants. The implications of this research include the potential production of forage sorghum with high Brix content for ruminant energy and Water-Soluble Carbohydrates (WSC) for silage production.
