Optimalisasi Produktivitas Ternak pada Lahan Suboptimal melalui Aplikasi Probiotik
Get PDFWiryawan, I. K. D. (2023). Optimization of livestock production at suboptimal lands through the application of probiotics. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 756-763). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Livestock development at suboptimal lands is less productive due to nutrition and environmental stress. Nutrition stress is caused by nutrients deficiency, toxin or antinutrients content of feed, whereas environmental stress is caused by improper livestock managements. Application of probiotics is one alternative that can be used to reduce the negative effects of nutrition and environmental stress. Probiotics supplementation in ruminants can be applied in calves as well as in adult cattle. Probiotics application in calves could reduce mortality rate due to diarrhea caused by pathogen or environtmental stress. Supplementation of probiotics in adult cattle could reduce the metabolic disorders such as acidosis, and methanogenesis. In addition, livestock development at suboptimal lands often uses feeds or forages containing toxins or antinutrients. Probiotic supplementation has the ability to reduce the toxins/antinutrients content in the feed which is beneficial to prevent its negative effects. Probiotic supplementation in chicken enhanced the productivity through the inhibition of pathogen infection. Based on our research, the livestock production at suboptimal lands can be optimized through the application of probiotics

(Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-11 Tahun 2023, Palembang 21 Oktober 2023. (pp. 104-109). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).One of the coconut diversification products is Virgin Coconut Oil (VCO), which is not only used for food but also for health/medicine. In the crude VCO filtering process stage, it can be done using adsorbent materials, but the selection of adsorbents needs to be selective regarding halal elements. Carbon-based coconut stem sawdust waste can be processed using the pyrolysis method to produce charcoal as a bioadsorbent in the VCO filtration process. This research aimed to characterize charcoal resulting from pyrolysis of coconut sawdust waste. Pyrolysis was carried out in a simultaneous pyrolysis reactor operated at a temperature of 400 oC, time 2.5 hours, flow rate of inert gas (Argon) 2 liters/minute. Characterization of charcoal products is carried out using proximate analysis. The characteristics of charcoal obtained are Ash Content 4.11%, volatile matter 16.85%, fixed carbon 76.57%, total sulfur 0.02%, gross calorific value 7229%. Based on this characterization it can be seen that the fixed carbon content is quite high and the sulfur content Very low or nil indicates that the charcoal resulting from pyrolysis of coconut trunk sawdust has the potential to be used as a bioadsorbent material in the VCO purification process
