Hidroponik adalah sistem bercocok tanam menggunakan media cair dan nutrisi-nutrisi yang diperlukan untuk pertumbuhan tanaman. Keuntungan bercocok tanam dengan hidroponik yakni tanaman tidak merusak tanah, tidak membutuhkan tempat yang luas, tanpa pestisida atau obat hama yang merusak tanah, mempercepat pertumbuhan dan menjaga kualitas tanaman. Penelitian ini menggunakan perbandingan konsentrat dan fodder jagung yakni P1 (100:0), P2 (60:40), P3 (75:25) dan P4 (0:100). Hasil penelitian menunjukan bahwa kuantitas susu pada hari ke-1, ke-2 dan ke-3 menunjukkan P4 berbeda nyata (p<0,05) dengan P1, P2, dan P3. Hal ini menunjukkan penurunan kuantitas susu pada P4 dan kuantitas susu terbanyak pada P1 dan P3. Simpulan penelitian perlakuan pemberian fodder jagung 25% dan konsentrat 75% serta perlakuan konsentrat 100% dapat meningkatkan kuantitas susu kambing Sapera.

Analisis kelayakan usaha berdasarkan kriteria kelayakan investasi meliputi Net Present Value (NPV), Net Benefit Cost Ratio (Net B/C), Internal Rate Return (IRR), Payback Periode (PP) dan R/C Ratio untuk analisis efisiensi produksi. Hasil penelitian menunjukkan besar pendapatan rata-rata per tahun sebesar Rp.141.669.425, dengan rata-rata penerimaan sebesar Rp.898.382.687 yang bersumber dari hasil penjualan susu, pedet jantan, sapi afkir, pejantan, sapi laktasi dan pupuk kandang. Berdasarkan hasil penelitian usaha layak untuk dijalankan karena semua kriteria investasi mampu dicapai, memiliki NPV>0 yaitu Rp.181.016.633, Net B/C>0 yaitu 1,15, IRR sebesar 12,3% lebih besar dari tingkat diskonto yang digunakan dan PP selama 7,2 tahun. Efisiensi produksi dinyatakan sudah efisien karena nilai R/C>0 yaitu 1,18.
Sapi Rambon merupakan salah satu sapi lokal Indonesia. Tahun 2017 populasi sapi Rambon mengalami penurunan. Salah satu upaya pelestarian sapi lokal adalah melalui peningkatan populasi sapi dan inseminasi buatan. Faktor penentu keberhasilan perkawinan salah satunya adalah libido tinggi dan kualitas semen. Motilitas spermatozoa dan viabilitas spermatozoa adalah salah satu indikator fertilitas spermatozoa dan kualitas semen. Penelitain ini adalah penelitian deskriptif. Penelitian ini bertujuan untuk mengetahui motilitas dan viabilitas semen segar sapi Rambon di Desa Kemiren Kecamatan Glagah Kabupaten Banyuwangi. Semen pada penelitian ini di tampung menggunakan vagina buatan dari 6 ekor sapi Rambon jantan. Pemeriksaan motilitas spermatozoa dan viabilitas spermatozoa dilakukan di klinik Linawati Banyuwangi. Hasil pada penelitian ini disajikan dalam bentuk tabel. Parameter penelitian ini adalah motilitas dan viabilitas spermatozoa sapi Rambon. Hasil pemeriksaan motilitas spermatozoa sapi Rambon 83,3±4,1% dan viabilitas spermatozoa sapi Rambon 86,7±2,3%. Kesimpulan dari penelitian menunjukan bahwa motilitas dan viabilitas spermatozoa sapi Rambon baik dan memenuhi syarat semen beku untuk inseminasi buatan.
Background and Aim: Antimicrobial resistance, especially antibiotic resistance, is one of the most severe public health challenges. Antibiotic resistance occurs when bacteria avoid and fight the mechanism of action of antibiotic drugs. This study aimed to determine the resistance of Escherichia coli from the milk of Ettawa crossbreed dairy goat at Blitar Regency, East Java, Indonesia, with the antibiotics streptomycin, sulfonamides, and trimethoprim. Materials and Methods: A total of 34 milk samples of Ettawa crossbreed dairy goats were used in this study. The initial stages of this research included tests of the physical properties, isolation, and identification of E. coli. Then, the E. coli isolates were tested for antibiotic resistance using the Kirby–Bauer method. Results: The results showed that all samples were positive for E. coli. The physical properties of milk, namely, color, odor, flavor, and consistency, were normal. The results of the alcohol test showed normal acidity, and the specific gravity of goat milk met the criteria, with an average specific gravity of 1.0295 g/mL. The results of the antibiotic resistance test showed that 4 (12%) samples were resistant to streptomycin, 5 (15%) to sulfonamide, and 3% to trimethoprim. Conclusion: The prevalence of E. coli from Ettawa crossbreed dairy goats in Blitar Regency, East Java, Indonesia, was 100%. Furthermore, this E. coli isolate exhibited resistance to antibiotics streptomycin, sulfonamides, and trimethoprim. The use of antibiotics in the dairy goat industry in Indonesia should be controlled to prevent the spread of resistant E. coli from animals to humans through the food chain and prevent the emergence of multidrug-resistant E. coli.
Background:The conservation of Bali bulls, the Indonesian native breed of cattle, is crucial for cattle breeding in Indonesia. To guarantee the spread of Bali bulls through artificial insemination the quality of the frozen semen must be high. To this end, using an extender material in addition to semen increasing spermatozoa's survival during cryopreservation is important. Green tea extract (GTE) can be used as cryoprotectant because its high antioxidant activity can help avoid reactive oxygen species formation.Methods: Semen of five Bali bulls from the National Artificial Insemination Center at Singosari, Indonesia was collected routinely twice a week. First, fresh semen inspection was performed to determine the feasibility of using Bali bulls as animal samples. The extender used in this study was Tris-based egg yolk. The divided samples into four treatments: T0 (no GTE added to the extender), T1 (0.05 mg GTE plus 100 mL extender), T2 (0.10 mg GTE plus 100 mL extender), and T3 (0.15 mg GTE plus 100 mL extender). The semen freezing process was conducted according to standard procedures and sperm quality parameters, i.e., sperm motility, viability, abnormalities, and membrane integrity observed pre-freezing and postthawing.Results: There were significant differences in total motility, progressive motility, viability, and integrity membrane of Bali bull sperm at both pre-freezing and post-thawing after adding GTE into the extender. In contrast, there were no differences in abnormalities among treatments. Conclusion:Adding GTE at a 0.15 mg into 100 mL Tris-based egg yolk extender can improve the quality of cryopreserved Bali bull sperm.
